FORWARD In March 2001, the National Institutes of Health issued the following warning: "The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading."1 Furthermore, because of the rapid increase in Internet-based information, many hours can be wasted searching, selecting, and printing. Since only the smallest fraction of information dealing with irritable bowel syndrome is indexed in search engines, such as www.google.com or others, a non-systematic approach to Internet research can be not only time consuming, but also incomplete. This book was created for medical professionals, students, and members of the general public who want to know as much as possible about irritable bowel syndrome, using the most advanced research tools available and spending the least amount of time doing so. In addition to offering a structured and comprehensive bibliography, the pages that follow will tell you where and how to find reliable information covering virtually all topics related to irritable bowel syndrome, from the essentials to the most advanced areas of research. Public, academic, government, and peer-reviewed research studies are emphasized. Various abstracts are reproduced to give you some of the latest official information available to date on irritable bowel syndrome. Abundant guidance is given on how to obtain free-of-charge primary research results via the Internet. While this book focuses on the field of medicine, when some sources provide access to non-medical information relating to irritable bowel syndrome, these are noted in the text. E-book and electronic versions of this book are fully interactive with each of the Internet sites mentioned (clicking on a hyperlink automatically opens your browser to the site indicated). If you are using the hard copy version of this book, you can access a cited Web site by typing the provided Web address directly into your Internet browser. You may find it useful to refer to synonyms or related terms when accessing these Internet databases. NOTE: At the time of publication, the Web addresses were functional. However, some links may fail due to URL address changes, which is a common occurrence on the Internet. For readers unfamiliar with the Internet, detailed instructions are offered on how to access electronic resources. For readers unfamiliar with medical terminology, a comprehensive glossary is provided. For readers without access to Internet resources, a directory of medical libraries, that have or can locate references cited here, is given. We hope these resources will prove useful to the widest possible audience seeking information on irritable bowel syndrome. The Editors

CHAPTER 1. STUDIES ON IRRITABLE BOWEL SYNDROME Overview In this chapter, we will show you how to locate peer-reviewed references and studies on irritable bowel syndrome.
The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and irritable bowel syndrome, you will need to use the advanced search options. First, go to http://chid.nih.gov/index.html. From there, select the “Detailed Search” option (or go directly to that page with the following hyperlink: http://chid.nih.gov/detail/detail.html). The trick in extracting studies is found in the drop boxes at the bottom of the search page where “You may refine your search by.” Select the dates and language you prefer, and the format option “Journal Article.” At the top of the search form, select the number of records you would like to see (we recommend 100) and check the box to display “whole records.” We recommend that you type “irritable bowel syndrome” (or synonyms) into the “For these words:” box. Consider using the option “anywhere in record” to make your search as broad as possible. If you want to limit the search to only a particular field, such as the title of the journal, then select this option in the “Search in these fields” drop box. The following is what you can expect from this type of search: •
Irritable Bowel Syndrome: Still Far from a Positive Diagnosis Source: Digestive Diseases and Sciences. 37(2): 164-167. February 1992. Summary: A scoring system has been proposed for the positive diagnosis of irritable bowel syndrome (IBS) where more than 44 points excluded organic digestive disease. This article reports on a study that attempted to determine the usefulness of this scoring system in a different setting. Patients (1257) consecutively referred to the authors' medical division were admitted to the study and 270 of these, complaining of abdominal symptoms, were scored on the Kruis system method. The positive predictive value and the sensitivity of the system did not appear to be adequate. The negative predictive value and the specificity gave higher results, but did not identify 11 cases of organic

Irritable Bowel Syndrome
digestive diseases. The authors conclude that the scoring system may be useful only as a first step in a diagnostic flow chart. 4 tables. 5 references. (AA-M). •
Antibiotic Use, Childhood Affluence and Irritable Bowel Syndrome (IBS) Source: European Journal of Gastroenterology and Hepatology. 10(1): 59-62. January 1998. Contact: Available from Rapid Science Publishers. 400 Market Street, Suite 750, Philadelphia, PA 19106. (800) 552-5866. Summary: Antibiotics cause well-defined short-lived disturbances in bowel habits. There is evidence to suggest that antibiotics may play a role in the pathogenesis of irritable bowel syndrome (IBS). This article reports on a study that consisted of a survey examining the relationship between drug use and other epidemiological correlates of IBS. Subjects were 421 people (46 percent male, mean age 47 years) attending a general practice health screening clinic. Subjects were interviewed by a research nurse and completed a previously validated questionnaire. IBS symptoms were said to be present if abdominal pain with two or more Manning criteria symptoms occurred more than once a month over the previous 6 months. Results showed 48 subjects with symptoms of IBS. The following were strongly related to its presence: antibiotic use, female sex, childhood living density of less than 1 person per room, and a manual occupation for the father. The use of nonsteroidal anti-inflammatory drugs, H2 antagonists, or other types of medication was not greater in this group. The authors conclude that antibiotic use is associated with IBS and call for further research into this association. In addition, privileged childhood living conditions were also an important risk factor consistent with an allergic etiology for IBS. 2 tables. 12 references. (AA).

Diarrhea-Constipation-Pain: When is It Irritable Bowel Syndrome? Source: Consultant. 41(8): 1089-1091, 1095-1096. July 2001. Contact: Available from Cliggott Publishing Company. 55 Holly Hill Lane, Box 4010, Greenwich, CT 06831-0010. Summary: Central to the diagnosis of irritable bowel syndrome (IBS) are the symptoms of abdominal pain and disordered defecation of at least 3 months' duration. This article helps physicians determine when the symptoms of diarrhea, or constipation, or pain are indeed due to IBS. Either diarrhea or constipation can predominate, although the defecation pattern may vary from day to day in some patients. In the absence of evidence of more serious disease, diagnosis is based largely on the results of a thorough history and examination. For most patients, general screening tests include a complete blood cell count, erythrocyte sedimentation rate, serum chemistry panel, stool guaiac test, and stool examination for ova (eggs) and parasites. For patients older than 50 years, flexible sigmoidoscopy, colonoscopy, or barium enema may be indicated. Management of IBS consists of patient education and reassurance; dietary modification, including increased fiber intake in patients with constipation; and in some cases, judicious use of medications or psychological interventions. 2 tables. 35 references.

Summary: Few data are available to evaluate health related quality of life (HRQOL) of people with irritable bowel syndrome (IBS). This article reports on a study that evaluated and compared the impact of IBS on HRQOL using previously reported HRQOL data for the United States general population and for people with selected chronic diseases. Using the SF 36 Health Survey, the authors compared the HRQOL of IBS patients (n = 877) with previously reported SF 36 data for the general U.S. population and for patients with gastroesophageal reflux disease (GERD), diabetes mellitus, depression, and dialysis-dependent end stage renal disease (ESRD). On all 8 SF 36 scales, IBS patients had significantly worse HRQOL than the U.S. general population. Compared with GERD patients, IBS patients scored significantly lower on all SF 36 scales except physical functioning. Similarly, IBS patients had significantly worse HRQOL on selected SF 36 scales than patients with diabetes mellitus and ESRD. IBS patients had significantly better mental health SF 36 scale scores than patients with depression. The authors conclude that IBS patients experience significant impairment in HRQOL. Decrements in HRQOL are most pronounced in energy and fatigue, role limitations caused by physical health problems, bodily pain, and general health perceptions. 3 figures. 4 tables. 44 references. •
Symptomatic Presentations of the Irritable Bowel Syndrome Source: Gastroenterology Clinics of North America. 20(2): 235-247. June 1991. Summary: Functional gastrointestinal disorders have no reliable physiologic, biochemical, or structural markers, therefore, they must be defined by their symptoms. This article discusses the classification of functional bowel disorders and describes the symptoms, particularly those of irritable bowel syndrome (IBS). Possible mechanisms underlying the symptoms are also mentioned. Disorders discussed include psychological disorders, IBS, burbulence, functional constipation, functional diarrhea, and unspecified functional bowel disorder. 1 figure. 2 tables. 71 references.

[email protected]. Summary: High fiber diet supplementation is commonly used in irritable bowel syndrome (IBS), although it poses several management problems. Partially hydrolyzed guar gum (PHGG) has shown beneficial effects in animal and human studies, but its potential role in IBS symptom relief has not been evaluated. This article reports on a study that investigated PHGG in IBS patients and compared it to a wheat bran diet. Abdominal pain, bowel habits, and subjective overall rating were longitudinally evaluated in 188 adults IBS patients (138 women, 49 men) for 12 weeks. Patients were classified as having diarrhea predominant, constipation predominant, or changeable bowel habits and were randomly assigned to PHGG or wheat bran. After four weeks, patients were allowed to switch group, depending on their subject evaluation of their symptoms. Significantly more patients switched from fiber to PHGG (49.9 percent) than from PHGG to fiber (10.9 percent) at four weeks. Per protocol analysis showed that both

Irritable Bowel Syndrome
fiber and PHGG were effective in improving pain and bowel habits, but no difference was found between the two groups. Intention-to-treat analysis showed a significantly greater success in the PHGG groups (60 percent) than in the fiber group (40 percent). In conclusion, improvements in core IBS symptoms (abdominal pain and bowel habits) were observed with both bran and PHGG, but the latter was better tolerated and preferred by patients, revealing a higher probability of success than bran and a lower probability of patients abandoning the prescribed regimen. 3 tables. 43 references. •
Psychophysiological Factors Associated with Irritable Bowel Syndrome Source: Gastroenterology Nursing. 17(2): 61-67. September-October 1994. Summary: In this article, the author reviews the psychophysiological factors associated with irritable bowel syndrome (IBS). The author addresses gastrointestinal neuroendocrinology; the effects of stress on gastrointestinal motility; and the nursing implications related to this syndrome. The mechanisms underlying the etiology of IBS remain to be elucidated. However, the author suggests that IBS is a stress-induced syndrome that involves the complex interactions between external or internal stressors, the central nervous system, and the enteric nervous system. 1 figure. 1 table. 44 references.

Serotonin-Transporter Polymorphism Pharmacogenetics in Diarrhea-Predominant Irritable Bowel Syndrome Source: Gastroenterology. 123(2): 425-432. August 2002. Contact: Available from W.B. Saunders Company. 6277 Sea Harbor Drive, Orlando, FL 32887-4800. (800) 654-2452. Website: www.gastrojournal.org. Summary: Irritable bowel syndrome (IBS) affects approximately 15 percent of adults, causes abdominal pain, discomfort, and altered bowel habits, and predominantly affects women. This article reports on a study of the use of serotonin (5HT) receptor antagonists in women with diarrhea- predominant IBS (DIBS). 5HT undergoes reuptake by a transporter protein (SERT). In the study, 30 patients (15 men, 15 women) with DIBS received 1 milligram twice a day of alosetron for 6 weeks; colonic transit was measured by scintigraphy at baseline and at the end of treatment. Results showed that SERT polymorphisms tended to be associated with colonic transit response; there was a greater response in those with long homozygous than heterozygous polymorphisms. Age, gender, and duration of IBS were not significantly different in the three groups (long, short, heterozygous). The authors conclude that genetic polymorphisms at the SERT promoter influence response to a 5HT antagonist in DIBS and may influence benefit to risk ratio with this class of compounds. 3 figures. 1 table. 57 references.

[email protected]. Summary: Irritable bowel syndrome (IBS) consists of various subtypes; it is unknown whether these subtypes share a common pathophysiology. Evaluation of motor and sensory function of the rectum using a barostat may help to explore a common pathophysiological background or differences in pathophysiology in subtypes of BIS.

This article reports on a study in which authors evaluated compliance, tone, and sensitivity of the rectum, in both fasting state and postprandially (after a meal), using a computerized barostat in 15 patients with diarrhea-predominant IBS (IBSD), 14 patients with constipation-predominant IBS (IBSC), and 12 healthy controls. Rectal compliance was decreased in both IBS groups compared with controls. The perception of urge was increased only in IBSD patients, whereas pain perception was significantly increased in both IBS groups. Spontaneous adaptive relaxation was decreased in IBSD patients. Postprandially, rectal volume decreased significantly in the controls and in IBSD patients, but not in IBSC patients. In conclusion, both rectal motor and sensory characteristics are different between IBSD and IBSC patients. Therefore, testing of rectal visceroperception, adaptive relaxation, and the rectal response to a meal may help distinguish groups of patients with different subtypes of IBS. 5 figures. 2 tables. 23 references. •

[email protected]. Website: www.blackwell-science.com. Summary: Irritable bowel syndrome (IBS) is a chronic, relapsing disorder of brain-gut regulation that can have disabling symptoms that significantly affect daily life. Recent advances in different aspects of IBS have led to a need to reassess the overall management of this common, complex disorder. Important areas include: first, the heterogeneity of symptom patterns and the role of specific diagnostic symptom criteria for use in both clinical practice and in clinical research; second, the growing interest in the potential interaction between 'peripheral' and 'central' pathophysiological mechanisms; and third, the development of new and effective drugs designed to target specific receptor systems in the enteric nervous system. This review article covers each of these aspects and emphasizes an approach to the management of patients based on pathophysiological considerations. 1 figure. 2 tables. 15 references.

[email protected]. Summary: Irritable bowel syndrome (IBS) is common in Caucasians and Japanese persons, but its epidemiology has not been studied in urbanized Chinese populations. This study compares diagnostic criteria and explores the epidemiology of IBS in Hong Kong Chinese. In all, 964 subjects from public housing and 334 subjects from private housing were recruited for face-to-face interviews in Shatin, Hong Kong. A structured questionnaire was used to measure the prevalence of IBS. The prevalence of IBS, based on the Rome II criteria, was 3.6 percent in men and 3.8 percent in women. Men with IBS had significantly lower vitality scores on the SF-36 scale than the controls and women with IBS had significantly lower mental health scores than controls. The authors conclude that IBS is quite prevalent in Hong Kong Chinese and the quality of life of subjects with IBS is significantly affected. 3 tables. 35 references.

Use of Antidepressants in Irritable Bowel Syndrome Source: Practical Gastroenterology. 26(3): 13-14, 19-20, 22-23, 27. March 2002. Contact: Available from Shugar Publishing. 12 Moniebogue Lane, Westhampton Beach, NY 11978. (516) 288-4404. Fax (516) 288-4435. Summary: Irritable bowel syndrome (IBS) is the most common bowel disorder seen in gastroenterology practice. IBS is characterized by a pattern of waxing and waning abdominal pain, bloating, and disturbance of bowel habits. This article describes the rationale for the use of antidepressants in IBS, the results of clinical trials, suggested treatment plan, and directions for future research. The authors note that IBS is a complex biopsychosocial disorder whose precise pathophysiology is unknown, although it is generally accepted that abnormal brain-gut interactions play a major role. At the time of clinical presentation, about 50 percent of IBS patients have a definable psychiatric disorder. Psychosocial stressors have been demonstrated to have an important modulatory role in IBS, affecting not only the illness experience but also health care seeking behavior and the clinical outcome. Antidepressants represent an attractive therapeutic approach for the treatment of IBS, not only for their psychotropic effects, but also for their neuromodulatory and analgesic properties. However, there is still a lack of well-designed, appropriately powered, randomized clinical trials examining the use of antidepressants in IBS. 1 figure. 4 tables. 51 references.

Irritable Bowel Syndrome: Streamlining the Diagnosis Source: Postgraduate Medicine. 102(3): 197-198, 201-204, 207-208. September 1997. Contact: Available from McGraw-Hill, Inc. 1221 Avenue of the Americas, New York, NY 10020. (612) 832-7869. Summary: Irritable bowel syndrome (IBS), a common gastrointestinal disorder, is the condition for which patients are most often referred to gastroenterologists. Symptoms may be distressing enough to cause avoidance of work and social activities. Stress often exacerbates symptoms, and sensory abnormalities are common in patients with the disease. In this article, the authors describe how careful history taking and physical examination can avoid the overuse of diagnostic testing and point to the most effective treatment. Differential diagnosis for IBS includes consideration of many common gastrointestinal illnesses, including parasitic infections, salmonellosis, celiac sprue (gluten intolerance), chronic pancreatitis, Crohn's disease, ulcerative colitis, peptic ulcer disease, colon cancer, Campylobacter jejuni infection, and endometriosis. A strong physician-patient relationship at the time of IBS diagnosis improves the patient's ability to cope with the disease and reduces the number of subsequent office visits. The physician needs to involve the patient as a collaborative partner in the decision-making process and to avoid extensive invasive procedures if there is no firm indication for them. The patient's concerns and fears need to be addressed. Dietary changes, specifically elimination of troublesome foods, such as sorbitol, alcohol, caffeine, fats, legumes, sugar and, in lactose-intolerant patients, milk products, may benefit IBS patients. Relief of colonic spasm may be obtained with short-acting anticholinergics and other antispasmodic medications. Loperamide may also prove to be beneficial, especially in reducing post-meal diarrhea. Antidepressants are now being evaluated as potential therapeutic agents for IBS.

Does a Physically Active Lifestyle Improve Symptoms in Women with Irritable Bowel Syndrome? Source: Gastroenterology Nursing. 24(3): 129-137. May-June 2001. Contact: Available from Williams and Wilkins. 351 West Camden Street, Baltimore, MD 21201-2436. (410) 528-8555. Summary: It has been proposed that physical activity moderates physiological or psychological responses to chronic conditions. This article reports on a study undertaken to determine if women with a chronic functional gastrointestinal (GI) disorder (irritable bowel syndrome, or IBS) had less active lifestyles than healthy controls. The study also tested whether active women with IBS had less severe recalled or daily reports of GI, psychological, and somatic symptoms than inactive women with irritable bowel syndrome. Questionnaires were used to measure GI and psychological distress and somatic symptoms in 89 women who participated in the study. A daily symptom and activity diary was kept for one menstrual cycle. Women with IBS were significantly less likely to be active (48 percent) than control women (71 percent). Within the IBS group, active women were less likely to report a feeling of incomplete evacuation following a bowel movement than inactive women, yet active women did not have less severe recalled psychological or somatic symptoms than inactive women. Active women with IBS reported less severe daily somatic symptoms, which were accounted for by a lower level of fatigue, but not daily GI or psychological symptoms. These results suggest that physical activity may produce select symptom improvement in women with IBS. 4 tables. 55 references.

[email protected]. Website: www.blackwell-science.com. Summary: Opioids change gut motility and secretion, causing delayed intestinal transit and constipation. Endorphins play a role in the constipation troubling some patients with irritable bowel syndrome (IBS); hence naloxone, an opioid antagonist, may have a therapeutic role. This article reports on a study undertaken to assess the efficacy and safety of an oral formulation of naloxone in IBS patients with constipation. The randomized, double-blind, placebo-controlled trial included 25 patients with IBS (constipation-predominant and alternating types) who received 8 weeks of treatment with naloxone capsules, 10 milligrams twice daily, or identical placebo. Adequate symptomatic relief was recorded in six of 14 on naloxone and three of 11 on placebo. Whilst the differences were not significant, improvements in severity gradings and mean symptom scores for pain, bloating, straining and urgency to defecate were greater with naloxone than placebo for all parameters. In addition, quality of life assessments improved to a greater extent in patients taking naloxone. The authors conclude that preliminary results suggest that naloxone is well tolerated and beneficial in patients with irritable bowel syndrome and constipation. A larger clinical trial is needed to provide sufficient statistical power to assess efficacy. 4 figures. 2 tables. 29 references.

Double-Blind Study of Nicardipine in Irritable Bowel Syndrome Source: European Journal of Gastrenterology and Hepatology. 3(2): 181-184. February 1991. Summary: Previous studies have suggested that calcium antagonists inhibit colonic motility and therefore may have therapeutic potential in irritable bowel syndrome (IBS). This article reports on a double-blind cross-over trial of the calcium antagonist nicardipine in 62 patients with IBS. Nicardipine significantly decreased whole gut transit time in constipated patients, but there was no effect on transit time in those with diarrhea, or on those with an alternating bowel habit. However, significant effects on general well-being, abdominal pain, abdominal distension or bowel habit were not observed. The authors conclude that this study suggests that nicardipine does not have a useful therapeutic effect in irritable bowel syndrome. 1 figure. 2 tables. 19 references. (AA-M).

Anxiety and the Irritable Bowel Syndrome: Psychiatric, Medical, or Both? Source: Journal of Clinical Psychiatry. 58(supplement 3): 51-61. 1997. Contact: Available from Physicians Postgraduate Press, Inc. P.O. Box 752870, Memphis, TN 38175-2870. Summary: The association between the irritable bowel syndrome (IBS) and psychiatric disorders is well-known to most clinicians, but the nature of the relationship is far from clear. There is an increased prevalence of psychiatric illness in IBS patients and an increase in IBS in psychiatric patients. Whether this association exists outside of treatment-seeking populations (i.e., in people with IBS who do not seek treatment) has not been well investigated. This article selectively reviews the existing literature regarding the association of IBS and psychiatric illness in both patient and nonpatient samples. The author presents a model of the brain-gut interaction, and offers a discussion of the practical implications of this model for treating individuals with IBS. The author considers patients with IBS and general anxiety disorder (GAD), panic disorder, posttraumatic stress disorder (PTSD), social phobia, and mood disorders. The treatment model suggests that, even in patients without psychiatric disorders, neuroactive medications may be a useful tool in improving functioning in individuals whose functional GI disorders have not responded to standard, conservative measures. Appended to the article is a discussion between three physicians on the concepts presented. 2 figures. 2 tables. 51 references. (AA-M).

[email protected]. Website: www.blackwell-science.com. Summary: The efforts of clinical researchers, lay organizations and pharmaceutical companies have increased the public profile of irritable bowel syndrome (IBS) and made it a respectable diagnosis. Diagnostic symptom criteria encourage a firm clinical diagnosis, which is the foundation of a logical management strategy. This article reviews the treatment of IBS, emphasizing that any plan of patient care begins with education. Reassurance that no structural disease threatens should be tempered with the reality that symptoms are likely to recur over many years. Patients expect diet and lifestyle advice, even if this is not specific to irritable bowel syndrome. Only a few of those with IBS see doctors, and even fewer see specialists. Therefore, the treating physician should ascertain the reason for the visit, the patient's fears and the presence of any comorbid illness, such as depression, that might require treatment in its own right. No drug treatment is useful for all of the symptoms of IBS, and many patients require no drug at all. If used, drugs should target the predominant symptom. Most patients with IBS need psychological support. Reassurance, discussion, and relaxation techniques can be provided by the family doctor. In all cases, successful treatment depends on a confident diagnosis and the strength of the doctor-patient relationship. 1 figure. 3 tables. 100 references.

Health-Related Quality of Life and Health Care Costs in Severe, Refractory Irritable Bowel Syndrome Source: Annals of Internal Medicine. 134(9 Part 2): 860-868. May 1, 2001. Contact: Available from American College of Physicians. American Society of Internal Medicine. 190 North Independence Mall West, Philadelphia, PA 19106-1572. Website: www.acponline.org. Summary: The irritable bowel syndrome (IBS) may lead to considerable impairment of health related quality of life (HRQOL) and high health care costs. It is not clear whether these poor outcomes directly result from severe bowel symptoms or if they reflect a
12
Irritable Bowel Syndrome
coexisting psychiatric disorder. This article reports on a study undertaken to determine whether bowel symptom severity and psychological symptoms directly influence HRQOL and health care costs. The cross sectional survey took place at secondary and tertiary gastroenterology clinics and included 257 patients with severe IBS who did not respond to usual treatments and who were recruited for a trial of psychological treatment. Predictors were abdominal pain, entries in a diary of 10 IBS symptoms, and measures of psychological symptoms. Outcomes were inability to work, HRQOL, and health care and productivity costs. Abdominal pain occurred on average 24 days per month and activities were restricted on 145 days of the previous 12 months. The mean Hamilton depression score was 11.3 plus or minus 6.1. The physical component summary score was low and the patients had incurred high health care costs over the previous year. Global severity and somatization scores on the Symptom Checklist, abdominal pain, and Hamilton depression scores independently contributed to the physical component score, but only psychological scores were associated with disability due to ill health. These variables did not accurately predict health care or other costs. History of sexual abuse was not an independent predictor of outcome. The authors conclude that both abdominal and psychological symptoms are independently associated with impaired health related quality of life in patients with severe IBS. Optimal treatment is likely to require a holistic approach. Since health care and loss of productivity costs are not clearly associated with these symptoms, alleviation of them will not necessarily lead to reduced costs. 2 figures. 3 tables. 28 references. •
Irritable Bowel Syndrome in Twins: Heredity and Social Learning Both Contribute to Etiology Source: Gastroenterology 121(4): 799-804. October 2001. Contact: Available from W.B. Saunders Company. 6277 Sea Harbor Drive, Orlando, FL 32887-4800. (800) 654-2452. Website: www.gastrojournal.org. Summary: The irritable bowel syndrome is a chronic functional gastrointestinal disorder characterized by abdominal discomfort or pain that beings with a change in the frequency or consistency of stool (diarrhea or constipation), that is relieved by defecation, and that is present in the absence of other diseases that could explain the symptoms. Heredity has been suggested to explain the finding that irritable bowel syndrome (IBS) tends to run in families. This article reports on a study undertaken to assess the relative contribution of genetic and environmental (social learning) influences on the development of IBS by comparing concordance rates in monozygotic (identical) and dizygotic (fraternal) twins to concordance between mothers and their children. Questionnaires soliciting information on the occurrence of more than 80 health problems, including IBS, in self and other family members were sent to both members of 11,986 twin pairs. The authors' analysis is based on 10,699 respondents representing 6,060 twin pairs. Concordance for IBS was significantly greater in monozygotic (17.2 percent) than in dizygotic (8.4 percent) twins, supporting a genetic contribution to IBS. However, the proportion of dizygotic twins with IBS who have mothers with IBS (15.2 percent) was greater than the proportion of dizygotic twins with IBS who have co-twins with IBS (6.7 percent). Logistic regression analysis showed that having a mother with IBS and having a father with IBS are independent predictors of irritable bowel status; both are stronger predictors than having a twin with IBS. Addition of information about the other twin accounted for little additional predictive power. The authors conclude that heredity contributes to development of IBS, but social learning (what an individual learns from those in his or her environment) has an equal or greater influence. 1 figure. 2 tables. 18 references.

[email protected]. Website: www.blackwell-science.com. Summary: The medical understanding of the pathophysiology of irritable bowel syndrome (IBS) has evolved from a motility disorder to a more integrated understanding of enhanced motility and visceral hypersensitivity associated with brain gut dysfunction. This article reviews recent work that supports an integrated approach to managing IBS. Psychosocial factors contribute to the predisposition, precipitation, and perpetuation of IBS symptoms and affect the clinical outcome. Newer brain imaging techniques (MRI, PET) may help physicians understand the relationship between altered emotional states with pain enhancement and other gastrointestinal symptoms. The author recommends diagnosis using symptom based (e.g., Rome) criteria and a conservative approach. A careful history will identify the need for diagnostic studies and treatments as determined by the nature and severity of the predominant symptoms. Treatment is based on an effective relationship between physician and patient and a combined pharmacologic and behavioral approach. For most patients with mild symptoms, dietary and lifestyle changes are usually sufficient for treatment. Newer medications acting at the 5-HT receptor may help reduce pain and bowel dysfunction. For more severe pain, antidepressants may be considered. 1 figure. 2 tables. 90 references.

[email protected]. Website: www.blackwell-science.com. Summary: The oral administration of the drug tegaserod causes gastrointestinal (GI) effects resulting in increased gastrointestinal motility (movement of contents through the GI tract) and attenuation of visceral sensation. This article reports on a study undertaken to determine the long term safety and tolerability of tegaserod in patients with irritable bowel syndrome (IBS) with constipation as the predominant symptom of altered bowel habits. The multicenter, open label study included 579 patients. Of these, 304 (53 percent) completed the trial. The most common adverse events, classified as related to tegaserod for any dose, were mild and transient diarrhea (10.1 percent), headache (8.3 percent), abdominal pain (7.4 percent), and flatulence (5.5 percent). Forty serious adverse events were reported in 25 patients (4.4 percent of patients) leading to discontinuation in 6 patients. There was one serious adverse event, acute abdominal pain, classified as possibly related to tegaserod. There were no consistent differences in adverse events between patients previously exposed to tegaserod and those treated for the first time in this study. The authors conclude that tegaserod appears to be well tolerated in the treatment of patients with constipation-predominant IBS. The adverse event profile, clinical laboratory evaluations, vital signs, and electrocardiogram recordings revealed no evidence of any unexpected adverse events, and suggest that treatment is safe over a 12 month period. 1 figure. 4 tables. 23 references.

need for the physician to establish a therapeutic relationship. Because of their safety and frequent placebo effect, a trial of fiber supplements is reasonable in all patients with IBS. The author discusses the treatments for patients in whom diarrhea predominates; those in whom pain, gas, and bloating predominate; and those in whom constipation is the primary problem. The author notes that, in all cases of IBS, regardless of the predominating symptom, the use of antidepressants, anxiolytics, and psychotherapy may be indicated for patients with associated affective disorders. 1 figure. 4 references. •

Irritable Bowel Syndrome Defined by Factor Analysis: Gender and Race Comparisons Source: Digestive Diseases and Sciences. 40(12): 2647-2655. December 1995. Summary: This article describes a study to examine the applicability across subgroups of the Manning criteria commonly used to diagnose the irritable bowel syndrome (IBS). A 22-item symptom questionnaire was administered to male and female African-American and Caucasian adults (n=1344). Consistent with the findings of a previous factor analytic study, three of the six Manning symptoms (loose stools and more frequent bowel movements with onset of pain, pain relieved by defecation) formed a cluster corresponding to the IBS in all subgroups. The researches conclude that the three core Manning symptoms have equal applicability to both genders and to African-Americans as well as to Caucasians. They are useful symptoms criteria for the diagnosis of IBS when used in conjunction with medical evaluation. 1 figure. 2 tables. 18 references. (AAM).

Diagnosis and Treatment of Irritable Bowel Syndrome Source: American Family Physician. 55(3): 875-880. February 15, 1997. Summary: This article discusses the diagnosis and treatment of irritable bowel syndrome (IBS), a common disorder characterized by symptoms of abdominal pain with diarrhea and or constipation. IBS is associated with significant disability and health care costs. The authors advocate a practical approach to diagnosis utilizing the symptombased Rome criteria. Management of patients has been helped by recent findings relating to the pathophysiology of the disorder. Dysregulation of intestinal motor functions, sensory functions and central nervous system functions is currently believed to be the basis for IBS symptoms. Symptoms are a result of both abnormal intestinal motility and enhanced visceral sensitivity. Psychosocial factors can affect the illness experience and the clinical outcome. The authors stress that an effective physicianpatient relationship is required for a successful outcome. Individualized treatment

American Gastroenterological Association Medical Position Statement: Irritable Bowel Syndrome Source: Gastroenterology. 112(6): 2118-2119. June 1997. Summary: This article presents guidelines to help physicians in the diagnosis and management of patients with irritable bowel syndrome (IBS). These guidelines were developed from a comprehensive review of the medical literature pertaining to IBS. The IBS is a combination of chronic or recurrent gastrointestinal (GI) symptoms not explained by structural or biochemical abnormalities, which is attributed to the intestines and associated with symptoms of pain and disturbed defecation and or symptoms of bloating and distension. The authors note that psychological stress exacerbates GI symptoms in everyone, but to a greater degree in patients with IBS. IBS adversely affects health-related quality of life, including impairment of physical and psychosocial function, disability, work absenteeism, and physician visits. A physical examination and the following studies are recommended for routine evaluation: complete blood count; sedimentation rate; chemistries; stool for ova, parasites, and blood; and flexible sigmoidoscopy or colonoscopy or barium enema with sigmoidoscopy if older than 50 years. The treatment strategy is based on the nature and severity of the symptoms, the degree of physiological disturbance and functional impairment, and the presence of psychosocial difficulties affecting the course of the illness. Patients with mild symptoms usually respond to education and reassurance and simple treatments not requiring prescription medication. A smaller proportion of patients with moderate symptoms have more disability and require pharmacological treatments directed at altered gut physiology or psychological treatments. 1 table. 1 reference.

[email protected]. Website: www.blackwell-science.com. Summary: This article reports on a literature review undertaken with three objectives: to compare the health related quality of life (HRQoL) of patients with irritable bowel syndrome (IBS) with that of health controls; to compare the HRQoL of irritable bowel syndrome patients to those with other diseases; and to examine therapy-associated changes in HRQoL of IBS patients. Searches of all English and non English articles from 1980 to 2001 were performed in MEDLINE and EMBASE and two investigators performed independent data abstraction. Seventeen articles met the selection criteria. Thirteen studies addressed objective number one; 11 of these studies showed a significant reduction in HRQoL among IBS patients. Of these, only one study was considered of high quality. Four studies addressed objective number two, none of which was considered to be high quality in addressing this objective. Four trials (three of high quality) addressed objective number three. One of these showed that symptomatic improvement with Leupron compared to placebo was accompanied by an improvement only in the comparative health domain of the HRQoL. The second study reported significant positive changes in HRQoL after 12 weeks of cognitive behavioral therapy. The third report of two placebo controlled studies indicated significant improvement with alosetron on most domains of IBS quality of life assessment instruments. The authors conclude that there is reasonable evidence for a decrease in HRQoL in patients with moderate to severe IBS. HRQoL in IBS patients is impaired to a degree comparable to other chronic disorders such as GERD and depression. A therapeutic response in IBS related pain has a corresponding improvement in HRQoL. 4 tables. 34 references.

Summary: This article reports on a study in which National Ambulatory Medical Care Survey data were used to compare health care resource utilization and frequency of physician visits for irritable bowel syndrome (IBS) with other functional and organic gastrointestinal (GI) disorders. IBS accounted for more than four million ambulatory office visits between 1997 and 1999. A substantial proportion of these IBS visits were by female patients, and a high percentage of the visits were to a gastroenterologist. IBS visits frequently included diagnostic or screening tests and mentions of medications. This evidence suggests that patients with IBS require considerable medical attention, which incurs substantial costs. The emergence of effective medications, as well as education of both patients and providers, may reduce resource utilization associated with IBS and facilitate the delivery of quality health care to patients. 4 figures. 3 tables. 9 references.

Sleep Disturbance Influences Gastrointestinal Symptoms in Women with Irritable Bowel Syndrome Source: Digestive Diseases and Sciences. 45(5): 952-959. May 2000. Contact: Available from Kluwer Academic/Plenum Publishers. 233 Spring Street, New York, NY 10013-1578. (212) 620-8000. Fax (212) 807-1047. Summary: This article reports on a study that evaluated the association between sleep disturbance and gastrointestinal symptoms in women with and without irritable bowel syndrome (IBS). The study also examined the role of psychological distress in this relationship. Women with IBS (n = 82) reported considerably higher levels of sleep disturbance compared with controls (n = 35), using both retrospective 7 day recall and daily diary recall for two menstrual cycles. The authors used daily diary data to estimate the association between sleep disturbance and gastrointestinal symptoms, both across women (i.e., whether women with high average sleep disturbance have higher average gastrointestinal symptoms) and within women (i.e., whether poorer than average sleep on one night is associated with higher than average gastrointestinal symptoms the following day). The regression coefficients for the across women effect are large and highly significant in both groups. The regression coefficients for the within woman effect are considerably smaller and statistically significant only in the IBS group. These regression coefficients showed little change when daily psychological distress or stress was controlled for, the one exception being the coefficient for the across women effect in the IBS group, which decreased substantially but still remained highly significant. Because it is possible that gastrointestinal symptoms could, in fact, cause poor sleep, the authors also fitted the temporally reversed model to evaluate the association between gastrointestinal symptoms on one day and sleep disturbance that night. The authors conclude that their results are consistent with the hypothesis that poor sleep leads to higher gastrointestinal symptoms on the following day among women with IBS. 1 figure. 2 tables. 41 references.

Abdominal Pain and Irritable Bowel Syndrome in Adolescents: A Community-Based Study Source: Journal of Pediatrics. 129(2): 220-226. August 1996. Summary: This article reports on a study to determine the prevalence of gastrointestinal (GI) symptoms, including abdominal pain in a community-based population of adolescents; whether a subgroup of these subjects have symptoms resembling irritable bowel syndrome (IBS); and whether anxiety and depression are more commonly found in adolescents with IBS-type symptoms compared with unaffected adolescents. The study included 507 subjects; abdominal pain was noted by 75 percent of all students. The pain occurred weekly in 13 to 17 percent of the subjects and was severe enough to affect activities in approximately 21 percent. IBS-type symptoms were noted by 17 percent of high school students and 8 percent of middle school students who reported abdominal pain. Anxiety and depression scores were significantly higher for students with IBS-type symptoms compared with those without symptoms. Eight percent of all students had seen a physician for abdominal pain in the previous year. These visits were correlated with abdominal pain severity, frequency, duration, and disruption of normal activities but not with anxiety, depression, gender, family structure, or ethnicity. 3 tables. 23 references.

Contact: Available from American College of Physicians. American Society of Internal Medicine. 190 North Independence Mall West, Philadelphia, PA 19106-1572. Website: www.acponline.org. Summary: This article reports on a study undertaken to evaluate the efficacy of pharmacologic agents (drugs) for irritable bowel syndrome (IBS). The study featured an electronic literature search (1966 to 1999) and a manual search of references from bibliographies of identified articles. Studies chosen for inclusion were randomized, double blind, placebo controlled, parallel or crossover trials of a pharmacologic intervention for adult patients; the studies had to report outcomes of improvement in global or IBS specific symptoms. Seventy studies met the inclusion criteria. The most common medication classes were smooth muscle relaxants (16 trials), bulking agents (13 trials), prokinetic agents (6 trials), psychotropic agents (7 trials), and loperamide (4 trials). The strongest evidence for efficacy was shown for smooth muscle relaxants in patients with abdominal pain as the predominant symptom. Loperamide seems to reduce diarrhea but does not relieve abdominal pain. Although psychotropic agents were shown to produce global improvement, the evidence is based on a small number of studies of suboptimal quality. Other treatment options, including psychotropic drugs, 5 hydroxytryptamine (5 HT) receptor antagonists, peppermint oil, and Chinese herbal medicine, require further study. 3 tables. 109 references.

Summary: This article reports on the development of recommendations for the diagnosis and management of irritable bowel syndrome (IBS) for European doctors delivering primary medical care. These recommendations can be adapted by local medical groups according to their language, custom, and health care systems. The workshop, planned by a steering committee, was attended by 21 general practitioners and gastroenterologists from Europe. After a state of the art symposium, four working groups considered the following aspects of IBS management: what to tell the patient, diagnosis, non medical treatment, and psychosocial management. Current and future drug management was reviewed by the steering committee. The process permitted a unique dialog between general practitioners and gastroenterologists, in which it was necessary to reconcile the specialists' emphasis on thoroughness with the practical, epidemiological, and economic realities of primary care. The recommendations emphasize education of the patient, a positive symptom based diagnosis, dietary and lifestyle advice, psychological support, and a critical analysis of current specific psychological and pharmacological (drug) treatments. Patient education should be tailored to the patient's ideas, fears and expectations and should take into account their understanding of their IBS symptoms. The information can include the following elements: the symptoms are real, not imagined or merely psychological; IBS is chronic and fluctuates in severity and duration; factors that trigger symptoms are multiple and vary among patients and over time; the mind-gut link explains how stress, emotions, perceptions and thoughts can affect the symptoms; and the symptoms are not life threatening. The recommendations remind readers that some symptoms cannot be explained by IBS and should trigger further diagnosis; these include: fever, anemia, bleeding from the gut, significant weight loss, family history of cancer or inflammatory bowel disease, recent change in bowel habit, over 45 years of age, and physical findings (e.g., an abdominal mass). 2 tables. 48 references. •

Summary: This article reviews current knowledge on irritable bowel syndrome (IBS), the most common disease diagnosed by gastroenterologists and one that affects about 20 percent of all people at any one time. IBS can be diagnosed positively on the basis of an established series of criteria and limited exclusion of organic disease. Symptoms

fluctuate, and the overall prevalence rate is relatively constant in Western communities. Ten percent of patients present to their physicians. The illness has a large economic impact on health care utilization and absenteeism. IBS is a biopsychosocial disorder in which three major mechanisms interact: psychosocial factors, altered motility, and or sensory function of the intestine. Management of patients is based on positive diagnosis of the symptom complex, limited exclusion of underlying organic disease, and institution of a therapeutic trial. If patient symptoms are intractable, further investigations are needed to exclude significant motility or other disorders. Symptomatic treatment includes fiber for constipation, loperamide for diarrhea, and low-dose antidepressants or infrequent use of antispasmodics for pain. The authors note that new pharmacological agents, psychotherapy, and hypnotherapy are being evaluated for their use in treating IBS. 5 figures. 6 tables. 109 references. (AA-M). •

Contact: Available from Lippincott Williams and Wilkins Publishers. 12107 Insurance Way, Hagerstown, MD 21740. (800) 637-3030. Fax (301) 824-7390. Summary: This article reviews recent research in irritable bowel syndrome (IBS). The authors note that converging evidence from investigations of the peripheral and central aspects of bidirectional brain gut interactions is beginning to shape a pathophysiological model of IBS and related functional gastrointestinal (GI) disorders. This neurobiological model includes alterations in autonomic, neuroendocrine, and pain modulatory mechanisms. The frequent association of IBS and other functional GI disorders with comorbid affective disorders and the temporal association of symptom exacerbation with psychosocial or physical stressors are consistent with alterations in the neurobiological mechanisms underlying the central stress response. The author discusses work in the area of alterations in central nervous system responses of the brain, neuroendocrine responses, autonomic dysfunction, and altered viscerosomatic sensitivity; peripheral modulators of visceral sensitivity; symptom based diagnosis; and affective disorders and psychosocial stressors. Depression and anxiety are the most common comorbid affective disorders in IBS. Classification of functional disorders according to these evolving biological markers holds the promise of a rational treatment design for subgroups of patients in the future. Renewed interest in drug development for IBS treatment has resulted in the development of diagnostic instruments for assessing the impact of symptoms on quality of life and in the development of compounds (drugs) undergoing clinical evaluation. 53 references (16 annotated).

Psychologic Considerations in the Irritable Bowel Syndrome Source: Gastroenterology Clinics of North America. 20(2): 249-267. June 1991. Summary: This article reviews recent studies regarding the psychological considerations in the irritable bowel syndrome (IBS). Topics covered include the self-selection hypothesis; diagnostic criteria; the psychologic symptoms and personality traits associated with IBS; learned illness behavior; the role of psychologic stress; psychologic treatment of IBS, including education and reassurance, managing fears and misconceptions, and scheduling return appointments; the use of antidepressant medications; and the role of psychotherapy, including behavior therapy and hypnosis. The authors conclude that psychologically-oriented treatments have a role in the management of IBS, even in patients who do not have a psychiatric disorder. 5 figures. 1 table. 51 references.

Questions and Answers: Food Allergy and Irritable Bowel Syndrome; Elective Appendectomy During Abdominal Surgery Source: JAMA. Journal of American Medical Association. 265(13): 1736, 1738. April 3, 1991. Summary: This brief article, one of a regular series of questions and answers, addresses two issues of interest to digestive diseases professionals. The first exchange discusses the possible role of food allergy in triggering or exacerbating irritable bowel syndrome (IBS). The responding author discusses the difference between food allergy and IBS, mentions research support for this hypothesis, and concludes that food allergy as a contributing factor in the pathogenesis of IBS is valid. The second exchange involves elective appendectomy during abdominal surgery. The responding author notes that there is little, if any, morbidity and that there is apparent benefit gained from incidental appendectomies, provided certain contraindications are taken into account. 7 references.

Summary: This consensus document reviews the current status of the epidemiology, social impact, patient quality of life, pathophysiology, diagnosis, and treatment of irritable bowel syndrome (IBS). Current evidence suggests that two major mechanisms may interact in IBS: altered gastrointestinal motility and increased sensitivity of the intestine. However, other factors, such as psychosocial factors, intake of food, and prior infection, may contribute to its development. Management of patients is based on a positive diagnosis of the symptom complex, careful history and physical examination to exclude risk factors for organic disease, and, if indicated, investigations to exclude other

disorders. Treatment choices include dietary fiber for constipation, opioid agents for diarrhea, and low-dose antidepressants or infrequent use of antispasmodics for pain, although the evidence basis for efficacy is limited or in some cases absent. Psychotherapy and hypnotherapy are the subject of ongoing study. Treatment should be tailored to patient needs and fears. Patient and physician education, early identification of psychosocial issues, and better therapies are important strategies to reduce the suffering and societal cost of IBS. 2 figures. 9 tables. 236 references. •

Box 50480, Boulder, CO 80322-0480. (800) 627-0484 or (303) 604-1464. Summary: This continuing education article reviews the nursing care for patients with irritable bowel syndrome (IBS). The authors note that it is now believed that IBS has a basis in visceral hypersensitivity (of the bowel wall) and abnormal gut motor function, possibly caused by anomalies in the gut brain connection. The syndrome is neither life threatening nor associated with the development of gastrointestinal diseases such as cancer, but IBS accounts for a significant number of medical visits and prescribed medications, as well as lost work time and reduced productivity. The syndrome tends to manifest with either diarrhea or constipation or with an alternating pattern of the two. Other common symptoms include mucus in the stool, a sensation of incomplete evacuation, looser or more frequent stools with pain, and relief of abdominal pain after defecation. It has been postulated that there are differences related to sex in motility patterns, symptom and psychological profiles, pain sensitivity, and access to health care. No one factor appears to be responsible for the symptoms in all patients with IBS. Diet, stressful events, and psychological distress may also exacerbate symptoms in vulnerable patients. Diagnosis of IBS occurs by exclusion; there is no biologic marker. Therapy usually focuses on the patient's predominant symptoms and can include patient education and reassurance, nonpharmacologic interventions, and pharmacologic (drug) interventions. One sidebar explores the connection between emotional (sexual) abuse and IBS, notably assessing the effect of self blame and self silencing. A posttest for receiving continuing education credits is appended to the article. 3 figures. 1 table. 50 references.

Summary: This editorial serves as an introduction to a series of articles on irritable bowel syndrome (IBS). The authors note that major events have occurred in the last five years that demonstrate the role of heightened sensation to visceral pain in patients with IBS. This work has been followed by a rapidly enlarging body of knowledge using PET scanning and functional MRI imaging to detect alterations in brain activation in IBS patients. The authors emphasize that IBS does not occur in a biological vacuum, i.e., patients who seek treatment for IBS are more psychologically disturbed than patients with IBS who do not choose to seek medical care, and patients with functional GI disorders are more likely to have suffered physical or sexual abuse than patients with structurally originated GI conditions. It has become clear that gender, psychosocial trauma, concomitant psychiatric disorders, and a patient's health beliefs all can influence

the acceptance of, adherence to, and improvement on a treatment regimen for IBS. The development of psychotherapeutic approaches, improvements in our understanding of the impact of gender and family history on treatment response, and the importance of screening for psychological disorders and psychosocial stress are all now recognized as key elements of optimal treatment. The series of articles (published in the same journal issue) reviews recent developments in the treatment of IBS using serotonergically active agents, antidepressants and antispasmodics, as well as the psychosocial dimensions that have an impact on optimal care of patients with IBS. 4 references. •

[email protected]. Website: www.blackwell-science.com. Summary: This review article summarizes the clinical evidence to support current therapies in irritable bowel syndrome (IBS). In patients with constipation predominant IBS, fiber is indicated at a dose of at least 12 grams per day. Loperamide (and probably other opioid agonists) are of proven benefit in diarrhea predominant IBS; loperamide may also aid continence by enhancing resting anal tone. In general, smooth muscle relaxants are best used sparingly, on an as needed basis, since their overall efficacy is unclear. Psychotropic agents are important in relieving depression and are of proven benefit for pain and diarrhea in patients with depression associated with IBS. Further trials with selective serotonic reuptake inhibitors (SRRIs) are underway. Psychological treatments, including hypnotherapy are less widely available but may play an

important role in pain relief. The author concludes that current therapies targeted on the predominant symptoms in IBS are moderately successful. However, therapies are needed to more effectively relieve this syndrome, not just symptoms. 1 figure. 3 tables. 60 references. •

[email protected]. Website: www.blackwell-science.com. Summary: This review article updates previous overviews of placebo controlled double blind trials assessing the efficacy and tolerance of smooth muscle relaxants used to treat irritable bowel syndrome (IBS). A total of 23 randomized clinical trials were selected for meta analyses of their efficacy and tolerance. Six drugs were analyzed: cimetropium bromide (five trials), hyoscine butyl bromide (three trials), mebeverine (five trials), otilium bromide (four trials), pinaverium bromide (two trials), and trimebutine (four trials). The total number of patients included was 1,888, of which 945 received an active drug and 943 a placebo. The mean percentage of patients with global improvement was 38 percent in the placebo group (n = 925) and 56 percent in the myorelaxant group (n = 927). The percentage of patients with pain improvement was 41 percent in the placebo group (n = 568) and 53 percent in the myorelaxant group (n = 567). There was no significant difference for adverse events. The authors conclude that myorelaxants are superior to placebo in the management of IBS. These drugs showed significant efficacy on the global assessment despite a high placebo effect (38 percent global improvement), with a range of difference from 31 percent for cimetropium to 11 percent for hyoscin. The efficacy was also significant and in the same range for pain relief, as well as for abdominal distension relief, although lower. There was no significant difference for transit abnormalities, diarrhea, or constipation. 4 figures. 1 table. 37 references.

[email protected]. Website: www.blackwell-science.com. Summary: Variation in the characteristics of irritable bowel syndrome (IBS) patients recruited for clinical trials from different sources could affect their response and the generalizability of trial results. This article reports on a study undertaken to describe and compare the characteristics of three different groups of IBS patients recruited into a 'mock clinical trial.' The authors enrolled 245 irritable bowel syndrome patients from three sources: 121 patients from British primary practitioners; 72 patients from California newspaper advertisements; and 52 from a California gastroenterologist's practice. The authors obtained demographic, clinical, and Hospital Anxiety and Depression (HAD) Scale data for each patient. Most patients were young to middle aged women; in all three groups, the majority reported symptoms for longer than 5 years. Subject characteristics varied among the groups. Typically, primary care patients were anxious, smokers, and daily alcohol drinkers who had sought care recently for IBS and had tried antispasmodic drugs. Their symptoms were intermediate in severity between

27
those of the other two groups. Advertisement subjects were the oldest, most highly educated, most often depressed, and were least likely to have sought care recently for symptoms, which were almost uniformly only moderate in severity. Gastroenterologist patients tended to be anxious and had nearly all sought care recently for symptoms, which were the most severe and most likely to include all three pain related Rome I criteria. The authors conclude that recruitment methodology affects important characteristics of an IBS study group. Trial reports should describe as completely as possible the recruitment method and the relevant subject characteristics to aid clinicians in deciding how the results might apply to their patients. 1 table. 26 references. •

This article discusses the definition, clinical features, epidemiology, causes and pathogenesis, diagnosis and differential diagnosis, treatment, and prognosis of IBS in the elderly. The authors stress that more study is needed, particularly in the areas of pathophysiology of IBS in the aged, investigation of personality, psychiatric symptomatology, mental state, and functional status in the elderly with IBS, and in documenting the prevalence and incidence of this phenomenon. 6 tables. 125 references.

Summary: Women with bowel disease commonly report that their symptoms worsen in relation to their menstrual cycle. This article reports on a study undertaken to determine the nature of gastrointestinal (GI) symptoms correlating with the menstrual cycle in women with inflammatory bowel disease and irritable bowel syndrome (IBS). This retrospective study involved 49 women with ulcerative colitis, 49 women with Crohn's disease (CD), 46 women with IBS, and 90 healthy community controls. Participants were interviewed using a questionnaire that included information on general health, medication history, pregnancy, and premenstrual and menstrual symptoms. Premenstrual symptoms were reported by 93 percent of all women but statistically more often by patients with CD. Patients with CD were also more likely to report increased GI symptoms during menstruation; diarrhea was the symptom reported most often. All disease groups had a cyclical pattern to their bowel habits significantly more than controls. Cyclical symptoms included diarrhea, abdominal pain, and constipation. The authors conclude that the prevalence of menstruation related symptoms is high and appears to affect bowel patterns. The physiological and clinical effects of the menstrual cycle should be taken into consideration when assessing disease activity. 3 figures. 2 tables. 13 references. (AA-M).

Project Title: A CASE CONTROL STUDY OF INTERSTITIAL CYSTITIS Principal Investigator & Institution: Warren, John W.; Professor; Medicine; University of Maryland Balt Prof School Baltimore, Md 21201 Timing: Fiscal Year 2003; Project Start 18-SEP-2003; Project End 31-AUG-2007 Summary: (provided by applicant): Interstitial cystitis (IC) is a chronic bladder disease manifested by severe bladder pain and urinary frequency and urgency. Using criteria established by the NIDDK, the diagnosis can be made by objective visible findings at cystoscopy. However, IC remains a disease of unknown etiology, inconvenient diagnosis, and unclear natural history. Women comprise 90% of IC cases for unknown reasons. Patients report less life satisfaction than those with end stage renal disease. Identification of risk factors is a proven method for providing clues to pathogenesis of a disease, yet a properly designed study of IC with incident cases, appropriate controls, and attention to disease onset date has never boon performed. Herein we propose such a study comprising national samples of incident IC cases and age and gender matched controls with rigorous attention to onset dates of symptoms. By telephone interview and medical record review, we will identify risk factors for IC and reveal non-bladder syndromes associated with IC. In this group of recent onset cases where a convenient diagnostic test would be most useful, we will test the utility of antiproliferative factor, a urinary factor discovered by Susan Keay of our group. We propose then to follow this well-investigated cohort of IC cases to initiate a natural history study of the disease. This project will allow us to test several hypotheses: 1. That certain features that precede onset of IC symptoms, e.g., bacterial cystitis, distinguish IC cases from controls matched for age and gender, and may be risk factors for the disease. 2) That patients with IC have higher prevalences of certain non-bladder syndromes, e.g., irritable bowel syndrome, than do matched controls. 3) That urine APF, HB-EGF, and/or EGF are sensitive and specific diagnostic markers for IC in patients with symptoms of <=12 months. 4) That patients with IC have remissions and that certain clinical features, e.g., bacterial cystitis at disease onset, are prognostic factors for remissions.

Physicians arrive at an lBS diagnosis following a protocol that uses standard endoscopic tests to exclude structural or biochemical abnormalities, a physical examination and a symptom questionnaire. This inefficient process leads to an enormous use of healthcare resources estimated at 3.5 million office visits and 2.2 million prescriptions at a direct and indirect cost of $29 billion annually. Our objective is to develop an easy to use, low cost breath test to diagnosis lBS. The test developed by Metabolic Solutions (MSI) is based on the principle that lBS patients malabsorb fructose. In preliminary studies MSI has demonstrated a novel technology using a carbon 13 tracer and unlabeled fructose to identify individuals with lBS by whether or not they can absorb the administered fructose. This is the first test to assay fructose malabsorption directly from the small intestine and correlate it to the diagnosis of LBS. The proposed test will significantly reduce national health care expenditures because proper diagnosis will lead to fewer office visits, more prudent use of drugs and better general health and well-being for a large number of Americans.

Project Title: A TWIN STUDY OF CHRONIC FATIGUE SYNDROME IN SWEDEN Principal Investigator & Institution: Pedersen, Nancy L.; Karolinska Institute Tomtebodavagen 11F Stockholm, Timing: Fiscal Year 2001; Project Start 15-AUG-2001; Project End 31-JUL-2004 Summary: Despite considerable research, fundamental questions about CFS remain at best partially answered. These questions include its definition, validity, the degree to which it results from genetic versus environmental factors, the nature of the substantial comorbidity observed with other conditions, and the basis of the female preponderance. The overarching aim of this project is to shed light on a number of basic questions about CFS via a large, population-based classical twin study. First, we will collect data on approximately 32,000 adults aged 42-65 years (13,000 complete twin pairs) who are members of the population- based Swedish Twin Registry for persistent fatigue, several overlapping conditions (fibromyalgia, irritable bowel syndrome, tension headache, allergy/eczema, generalized anxiety disorder, and major depression), and a detailed medical history. Second, the medical records of all twins who appear to have CFS-like illness and a subset of those with "CFS-explained" will be requested via an efficient

Irritable Bowel Syndrome
national retrieval system. Following expert review, these individuals will be classified in regard to the CDC CFS criteria. Obtaining these unique data will allow us to address a set of critical questions regarding CFS. First, we will estimate the prevalence of CFS and its common comorbidities (fibromyalgia, irritable bowel syndrome, tension headache, allergy/eczema, generalized anxiety disorder, and major depression) in one of the largest samples yet studied. Second, we will use a variety of multivariate techniques to derive an empirical typology of prolonged fatigue and to assess how this typology compares to the CFS definition. Third, we will quantify the genetic and environmental sources of variation for CFS and its comorbid conditions. Fourth, critically, we will examine the influence of gender on these sources of variation. Finally, we will analyze the patterns of comorbidity between CFS and fibromyalgia, irritable bowel syndrome, tension headache, allergy/eczema, generalized anxiety disorder, and major depression using multivariate twin analyses and thereby to estimate the extent of overlap between the shared and unique genetic and environmental sources of variation. In concert with other twin studies being conducted by the investigators and their collaborators, we hope to hasten progress in understanding the etiology of CFS by parallel studies in multiple populations. The current proposal has several unique aims and represents a costeffective means to extend this work in an epidemiological sample that is arguably the best twin registry in the world.

Project Title: ALPHA-2 ADRENERGIC CONTROL OF COLONIC FUNCTION IN IBS Principal Investigator & Institution: Camilleri, Michael L.; Professor of Medicine and Physiology; Mayo Clinic Rochester 200 1St St Sw Rochester, Mn 55905 Timing: Fiscal Year 2001 Summary: Our hypotheses are that alpha-2 adrenergic mechanisms modulate colonic sensation in health and in patients with irritable bowel syndrome associated with increased frequency of bowel movements and urgency; and that lower doses of the alpha-2 agonist, clonidine, are required to reduce colonic sensation in IBS compared to health; these antinociceptive effects are achieved without altering colonic compliance or motor function in patients with irritable bowel syndrome. The specific aims of the study are to study the alpha-2 adrenergic modulation of colonic compliance, tone and sensation in healthy human volunteers; to study the alpha-2 adrenergic modulation of gastrointestinal and colonic transit time in healthy human volunteers; and to study the alpha-2 adrenergic modulation of colonic transit, tone, compliance, and sensation in patients with well-characterized autonomic function who have irritable bowel syndrome associated with increased frequency of bowel movements and/or urgency.

Project Title: AUTONOMIC CONTROL OF BODY WEIGHT AND FEEDING Principal Investigator & Institution: Powley, Terry L.; Distinguished Professor; Psychological Sciences; Purdue University West Lafayette West Lafayette, in 479072040 Timing: Fiscal Year 2002; Project Start 01-JAN-1980; Project End 30-NOV-2006 Summary: The proposed project continues a programmatic investigation of the neural mechanisms of feeding and body weight regulation. The long- range goal of the project is a comprehensive functional neuroanatomy of energy homeostasis. For the immediate future, the proposed experiments concentrate on a series of structure-function analyses of the vagus nerve. Extensive evidence has established that the vagus, the Xth cranial
Studies
31
nerve, is critically involved in controlling ingestion and body energy regulation. Presently, however, continued progress in analyzing vagal mechanisms involved in ingestive behavior and physiology is seriously limited by a lack of fundamental structural information about the vagal projections to the gastrointestinal tract. Hence, the immediate goal of the project is the completion of a series of promising analyses that are characterizing the morphological types, regional topographies and functions of vagal projections linking the brain and GI tract. The first aim is to complete a series of experiments on vagal afferent, or sensory, endings in the alimentary canal. This aim includes characterizing structurally and then classifying afferent terminals in the mucosa and submucosa of the GI tract. It also includes developing topographic maps of the concentrations of these chemo-, osmo-, thermo- and mechano- receptors throughout the GI tract. The second aim is to characterize the patterns and timetables of regeneration of each of the different types of vagal projections to the GI tract. These experiments will also correlate the newly identified patterns of structural plasticity with recovery of function. The third aim is to extend our structure-function analyses by screening mutant mice with selective afferent vagal ablations for potential alterations in feeding behavior. Inventories of the different vagal endings, surveys of their terminal distributions, and characterizations of the plasticity in these vagal projections produced by damage or mutation will yield information needed to design, guide and interpret both experimental and surgical manipulations of the autonomic nervous system and GI tract. The program outlined also will extend our understanding of major neural mechanisms implicated in metabolic and digestive diseases including obesity, eating disorders, anorexia, disorders of swallowing, diabetes, vagal dysfunction, autonomic neuropathies, visceral pain, irritable bowel syndrome, and peptic ulcers.

Project Title: BIOMECHANICS OF ESOPHAGEAL WALL AND VISCERAL SENSATION Principal Investigator & Institution: Mittal, Ravinder K.; Professor of Medicine; Veterans Medical Research Fdn/San Diego Foundation of San Diego San Diego, Ca 92161 Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 30-JUN-2005 Summary: (provided by applicant): The biomechanical properties of the esophagus have relevance to its motor and sensory function. These properties have been studied in the animals and humans by several investigators using various techniques. However, there are limitations with each of these techniques. We have developed a novel system of balloon ultrasonography that measures esophageal pressure, radius and wall thickness simultaneously, in vivo, in humans. Our technique, therefore, allows accurate measurement of the wall stress, strain and elastic modulus (wall rigidity) on a continuous time basis. Our preliminary data show that in normal subjects there is a close temporal correlation between increase in intraluminal pressure and esophageal wall thickness, which allows the esophagus to maintain a low wall stress. Patients with motility disorders of the esophagus have a thicker esophageal muscularis propria compared to normal subjects. We hypothesize that difference in the biomechanical properties of the esophageal wall between normal subjects and patients is the reason for impaired esophageal transport and dysphagia in patients with motility disorders of the esophagus. The current understanding is that hypersensitivity of the esophagus is the cause of esophageal pain. Patients with presumed esophageal pain respond to distension of the esophagus at lower balloon volumes than normal subjects. The site of esophageal hypersensitivity may be at either the peripheral (esophageal wall) or at the central level (CNS). The latter is currently the favored site. The differences in the
32
Irritable Bowel Syndrome
biomechanical properties of the esophageal wall in patients and normal subjects may result in different wall stress and strain in response to the same volume of distension. We hypothesize that differences in the biomechanical properties of the esophagus may be the reason for a hypersensitive esophagus. The specific aims of our studies are: 1: In vitro validation of the novel technique of balloon-ultrasonography. 2: To determine biomechanical properties of the esophagus in normal human subjects using balloon ultrasonography and to determine the relationship between esophageal pain and its biomechanical properties. 3: To define the abnormalities of muscularis propria thickness in patients with primary motility disorders of the esophagus. 4: To determine the biomechanical properties of the esophageal wall in patients with a normal and thick muscularis propria and its relationship to esophageal hypersensitivity. 5: To study biomechanics of the esophageal wall in patients with esophageal dysphagia. We believe that our observations have important implications in understanding the mechanisms of esophageal motor and sensory function in healthy and diseased states. Furthermore, the principles discussed in the esophagus may be applicable to the understanding of visceral hypersensitivity seen in irritable bowel syndrome and other functional disorders of the GI tract.

Principal Investigator & Institution: Robinson, Michael; Clinical & Health Psychology; University of Florida Gainesville, Fl 32611 Timing: Fiscal Year 2003; Project Start 15-MAR-2003; Project End 31-DEC-2006 Summary: (provided by applicant): This project is designed to investigate the neural mechanisms of placebo analgesia. An innovative placebo protocol that assesses the placebo response to both visceral and cutaneous pain stimulation will be employed. Functional Magnetic Resonance Imaging (fMRI) will enable the characterization of brain mechanisms involved in placebo analgesia in a clinical population which experiences visceral pain as part of their clinical syndrome. This project will capitalize on previous work with Irritable Bowel Syndrome (IBS) patients where differential brain activation was demonstrated to visceral and cutaneous pain stimuli. In this same population a powerful and reliable placebo response to specific expectancy response sets has been demonstrated. The proposed project will combine these protocols to obtain brain images of IBS subject during natural history, placebo, and active agent (rectal lidocaine) conditions. It is anticipated that results will show that the placebo response will selectively activate specific brain regions. Neural activity (as measured by rCBF) will be greater in natural history conditions as compared to placebo conditions in the following brain regions: - lateral and/or medial thalamus, somatosensory areas 1 and 2, insular cortex, anterior cingulate cortex (ACC), posterior cingulate cortex (PCC), and prefrontal cortex. Furthermore, placebo mechanisms that operate primarily through attenuation of nociceptive signals at lower nervous system levels (spinal cord) will be evidenced by decreased thalamic, somatosensory, ACC, and PCC activation. Previous research indicates that expectancy and desire for pain relief will significantly predict the pain reduction from placebo. It is anticipated that these measures will also be associated with the above described brain activation patterns. By comparing the placebo conditions to the rectal lidocaine condition, brain and central nervous system related mechanisms versus peripheral (receptor site) related mechanisms will be differentiated.

Project Title: BRAIN/PELVIC VISCERA INTERACTIONS IN PSYCHIATRIC DISEASE Principal Investigator & Institution: Valentino, Rita J.; Professor; Children's Hospital of Philadelphia 34Th St and Civic Ctr Blvd Philadelphia, Pa 19104 Timing: Fiscal Year 2001; Project Start 05-SEP-1998; Project End 31-AUG-2003 Summary: A striking feature of mood and anxiety disorders is their frequent coexistence with functional bowel disorders, such as irritable bowel syndrome. Conversely, psychiatric symptoms are prevalent in subjects diagnosed with functional bowel disorders, which occur in 10-20% of adults. These clinical observations implicate neural substrates linking the brain and gastrointestinal tract in pathology that is prevalent in the adult population. In the current application, a specific circuit linking the forebrain and gastrointestinal tract is proposed. It is proposed that Barrington's nucleus, via divergent projections to the brain noradrenergic nucleus, locus coeruleus (LC) and autonomic parasympathetic nuclei, is in a position to co-regulate brain noradrenergic activity and autonomic parasympathetic activity and thereby coordinate forebrain activity with gastrointestinal function. The proposed aims will provide anatomic and functional evidence for this hypothesis: The specific aims are: (1) Identify regions of the gastrointestinal tract that are linked to the LC via Barrington's nucleus. Transsynaptic tracing (using pseudorabies virus) from the colon, cecum and bladder will be combined with retrograde tract tracing from the LC to determine whether Barrington's LCprojecting neurons also project to preganglionic neurons innervating these organs; (2) Characterize the physiological impact of Barrington's sacral spinal-projections on colon function. Barrington's nucleus has been studied only with regard to its role in micturition. Its projections to the sacral parasympathetic nucleus suggest that it also regulates distal colon function. This hypothesis will be tested by characterizing the effects of selective chemical stimulation of Barrington's nucleus on colonic intraluminal pressure: (3) Determine the role of Barrington's LC-projections in arousal elicited by colon or bladder distension. Colon and bladder distension increase LC discharge and produce arousal as indicated by forebrain electroencephalographic (EEG) activation. The hypothesis that forebrain arousal elicited by colon or bladder distension is mediated by Barrington's projections to the LC will be determined using micro infusion of drugs to selectively inactivate the LC or Barrington's nucleus. Together, these AIMS will begin to elucidate the anatomy and functions of a novel circuit that it is in a position to coordinate forebrain and gastrointestinal activity; a circuit that could play a role in the prevalent disorders that are characterized by a coexistence of psychiatric and gastrointestinal symptoms.

Principal Investigator & Institution: Greenwood-Van Meerveld, Beverly; Scientific Director; Oklahoma Foundation for Digestive Res Digestive Research Oklahoma City, Ok 73104 Timing: Fiscal Year 2001; Project Start 30-SEP-2000; Project End 28-FEB-2003 Summary: Irritable bowel syndrome (IBS) symptoms are due in part to alterations in visceral sensation. IBS symptoms are frequently exacerbated by stress and anxiety, which suggests a link between cognitive and peripheral autonomic activity. The amygdala has been implicated as a key limbic structure involved in anxiety and activation of the hypothalamic-pituitary-adrenocortical axis. It has been demonstrated that administration of glucocorticoids in the area of the amygdala increases anxiety in rats. Furthermore, rats genetically predisposed to heightened levels of anxiety display a hypersensitive response to colonic distention. The PI hypothesizes that manipulation of amygdala function by glucocorticoids induces colonic hypersensitivity through modulation of spinal neuronal activity. The PI proposes to modulate anxiety by manipulating amygdala function directly with corticosterone and specific glucocorticoid antagonists to determine mechanisms by which the CNS regulates visceral sensitivity. Visceromotor reflexes in response to colorectal distention will be used to determine visceral hypersensitivity in rats with normal and "hypersensitive" colons. It is proposed that chronic stress resulting in elevated glucocorticoid levels could, through the amygdala, modulate the function of critical spinal neurons involved in the colonic stimuli. To further explore the mechanisms involved the PI will modulate amygdala function with glucocorticoids and its effect on spinal cord neuronal activity. Recordings will be made from rat lumbosacral spinal nerves in response to colonic distention following treatment with corticosterone or specific antagonists delivered to the amygdala. This R21 proposal will develop collaborations among scientists in GI neurophysiology, pharmacology, and neuroendocrinology.

Principal Investigator & Institution: Raybould, Helen E.; Associate Professor; Clinical Research Center; University of California Davis Sponsored Programs, 118 Everson Hall Davis, Ca 95616 Timing: Fiscal Year 2001; Project Start 01-AUG-1989; Project End 31-AUG-2004 Summary: Nutrients in the intestinal lumen initiate changes in motor function of the gastrointestinal tract. Intestinal lipid acts via a cholecystokinin A receptor- (CC.-AR) and a vagal afferent-dependent pathway. The hypothesis to be tested is that intestinal lipidinduced inhibition of gastric motility is dependent on absorption of lipid by enterocytes, formation and release of chylomicrons and apolipoprotein A-IV (apoA-IV), release of CCK. by apo A-IV and CCK acting on CCK-ARs on intestinal afferent nerve terminals. To test this hypothesis, studies are proposed to determine that: (1) inhibition of gastric emptying by lipid in the intestinal lumen depends on chylomicron formation and release of apo A-IV; (2) release of CCK in response to lipid is dependent on chylomicron formation and release of ap A-IV; (3) activation of vagal afferents in response to intestinal lipid is dependent on release of apo A-IV and CCK-AR activation and (4) to demonstrate the expression of CCK-AR on neuronal elements in the stomach and duodenum and their functional regulation by CCK. The role of chylomicron formation in lipid- induced inhibition of gastric emptying or motility and release of CCK will be determined in rats using the surfactant pluronic L81. Postabsorptive chylomicron products in mesenteric lymph will be given intra-arterially to demonstrate their effectiveness to inhibit gastric motility and act via a CCK-AR- and vagal capsaicindependent pathway. The role of apo A-IV in inhibition of gastric motility and CCK release in response to lipid will be determined by in vivo immunoneutralization, removal of apo A-IV from chylous lymph by immunoprecipitation, and by exogenous administration of apo A-I. Lipid-induced inhibition of gastric emptying and release of CCK will be measured in apo A-IV over-expressing and apo A-IV knockout mice. CCK secretion from STC-1;cells will be measured in vitro to determine that apo A-IV acts direct on endocrine cells. Intestinal vagal afferent fiber discharge will be measured in response to intestinal perfusion of lipid and exogenous administration of apo A- IV acts directly on endocrine cells. Intestinal vagal afferent fiber discharge will be measured in response to intestinal perfusion of lipid and exogenous administration of apo A-IV and determine that both of these responses are CCK-AR- dependent using the CCK-AR antagonist devazepide. A direct effect of Cck on vagal afferents innervating the gastroduodenum will be determined by measuring calcium fluxes in response to CCK in nodose neurons in vitro. The cellular sites of expression and origins of Cck-ARs will be determined in immunohistochemical studies using antisera raised to different regions of the rat CCK-AR in tissue from intact, extrinsically denervated or capsaicin treated rats The co- localization of CCK-AR with other enteric neuropeptides, and with neuronal and endocrine CCK will be determined in double labeling experiments. The functional regulation of Cck- Ars in the stomach and duodenum will by investigated using exogenous and endogenous CCK and devazepide. These studies address sensory transduction in the gastrointestinal tract which is important in the regulation of normal digestive function. There is evidence that sensory function of the intestine is altered in pathological conditions such as inflammatory bowel disease, irritable bowel syndrome and obesity. A greater understanding of these sensory mechanisms will help in understanding the pathophysiology of these diseases.

Project Title: COGNITIVE APPROACHES TO MODIFYING HUMAN PAIN PERCEPTION Principal Investigator & Institution: Bushnell, M. Catherine.; Professor; Mc Gill University James Admin. Bldg., Room 429 Montreal, Pq H3a 2T5 Timing: Fiscal Year 2002; Project Start 10-SEP-2002; Project End 31-AUG-2006 Summary: (provided by applicant): The vast majority of analgesic research has focused on pharmacological agents, addressing particularly the peripheral and spinal cord mechanisms of opioid and anti-inflammatory therapy. It is now recognized, however, that a variety of modulatory mechanisms exists in the nervous system, and more importantly, that many of these endogenous pathways can be accessed through cognitive manipulations. The proposed research investigates a number of cognitive factors that modulate pain perception, examines their interrelationships, and explores possible cerebral mechanisms underlying their action. Study 1 will test the hypothesis that emotional context influences pain perception independent of attentional factors. Psychophysical studies in normal human subjects will employ cross-modality attention tasks, hedonically charged olfactory stimuli (to modify emotional context), and noxious heat as a painful stimulus. Functional magnetic resonance imaging (fMRl) will subsequently examine cerebral activation associated with these cognitively activated pain-modulatory systems. Study 2 will test the general hypothesis that cognitive modulation of pain perception is more pronounced for visceral than for cutaneous stimuli, as suggested by clinical evidence indicating a strong influence of emotional state on chronic visceral pain, such as the pain of irritable bowel syndrome or non-cardiac chest pain. This study will address the issue experimentally, using psychophysical and fMRl testing to compare directly the influence of emotional context and/or attentional state on sensory and affective aspects of visceral and cutaneous pain perception in normal human subjects. Finally, based on recent suggestions of gender dissimilarities in endogenous pain-modulatory systems, we will examine, in the above studies, sexrelated differences in the modulatory influences of emotional context and attention on both the sensory and affective dimensions of pain perception. The influence of a patient's cognitive state on pain has been largely ignored in western medicine. Results of the proposed studies may help educate both physicians and patients about cognitive effects on pain and guide future development of cognitive strategies for pain control.

Evidence from studies of phenomenology, comorbidity, family history, and pharmacologic treatment response suggest that fibromyalgia may be associated with major mood disorder, and possibly to a proposed group of conditions known as affective spectrum disorders. Prior psychiatric research has demonstrated that major mood disorder is highly familial. Family history studies provide a method by which to assess how medical disorders co-aggregate in families and, therefore may share a common risk factor or pathophysiologic mechanism. To date, few studies have explored the morbid risk of major mood disorder (and other proposed affective spectrum disorders) in probands with fibromyalgia and their first- degree relatives. All of these studies have used the family history method, which entails interviewing probands regarding their knowledge of psychiatric illness in relatives. Although most of these studies have provided important preliminary data suggesting an association between fibromyalgia and major mood disorder, this method has been demonstrated to be less sensitive in detecting illness in relatives than direct interview (the family interview method). In order to provide further evidence of a relationship between fibromyalgia and major mood disorder, we propose to study the prevalence of psychiatric and rheumatologic disorders in probands with fibromyalgia and their firstdegree relatives as compared to probands with rheumatoid arthritis and their relatives using the family interview method. In addition to assessing the degree of co-aggregation of these disorders within families, we will also study the occurrence of other conditions within the proposed group of affective spectrum disorders in relation to fibromyalgia, and the association between the severity of fibromyalgia symptoms and the presence of major mood disorder within families.

The primary goal of this core is to facilitate collaboration, education about, and performance of GI clinical trials, human physiological studies, and health service studies in digestive diseases. The traditional focus of the core has been the investigation of peptic diseases and upper GI physiology, including secretion, motility, and hormonal regulation. This focus has been broadened to include the study of other important gastrointestinal illnesses such as complicated ulcer disease, gastroesophageal reflux disease (GERD), Barrett's epithelium, GI hemorrhage, non-ulcer dyspepsia, Helicobacter pylori infection, pre-cancer conditions (gastritis, polyposis, and ulcerative colitis), and inflammatory bowel disease. An overriding theme of the core is the study of the physiology of visceral pain which may be associated with all of these disorders. The importance of this area in GI diseases is highlighted by the impact of GI symptoms on quality of life and demand for health care services. With this in mind, the core has greatly expanded the study of neuroenteric diseases such as irritable bowel syndrome (IBS), non-ulcer dyspepsia, and non-cardiac chest pain. The specific goals of this core are to provide CURE investigators, trainees, and their collaborators with access to: (1) a quality clinical research unit for performance of GI clinical research at a low cost, (2) utilization of fully equipped endoscopy units for GI clinical and physiologic research studies, (3) laboratory services for GI secretory tests, GI motility and pH testing, and H. pylori assessments (ELISA, C-14 breath testing, and histopathology), (4) teaching of clinical research techniques and consultation about study design, data management, statistical analysis, and routine outcomes, (5) tissue and clinical data banks of patients with selected GI diseases (the largest data bases are for GI hemorrhage and functional GI disease), (6) consultation about conducting health services research including design of studies, cost assessments, quality of life instruments, effectiveness studies, and modeling cost-effectiveness studies, (7) specialized equipment for GI studies (such as equipment for ablating Barrett's epithelium or endoscopic ultrasound instruments), (8) psychophysiology and GI motility laboratories for the study of neuroenteric diseases, and (9) utilization of a brain imaging unit for the study of neuroenteric diseases. The instruments and personnel required for these services and functions are expensive, so that sharing them among various investigators in a core is cost effective and promotes collaboration.

In phase one, 260 patients will be randomized to a 3 week three arm RCT comparing: 1. sham needle treatment (a validated sham acupuncture placebo device) given in the context of a patient-practitioner interaction 'augmented' with positive cognitive, emotional and symbolic interactions, 2. identical sham given within a 'limited' contextual interaction, 3. a no treatment control. The primary question tested is whether the 'nonspecific' effects across the two sham device arms and the no treatment arm behave monotonically in a manner analogous to 'dose dependence' i.e. is 'augmented' arm > 'limited arm' > wait-list natural history. This trial also allows us to answer whether 1. the placebo effect in IBS can be enhanced, i.e., does an 'augmented' placebo intervention elicit a greater placebo effect than a 'limited' placebo intervention and 2. whether the 'limited' placebo intervention elicits a greater placebo effect than natural history arm with any 'non-specific' effects attendant to being in a no-treatment control. To maintain ethical norms, phase two will continue the same context, but sham acupuncture will seamlessly be switched to verum acupuncture to explore acupuncture's efficacy in IBS. In addition, a second parallel qualitative study will follow 27 additional patients (whose outcome data will be excluded from the larger study's analysis) through the same three arms; the study will use interviews to explore the relationships between patients' interpretations and understandings (what anthropologists call 'meaning') of IBS, and their responses to placebo and verum treatment.

Project Title: FUNCTIONAL BOWEL DISORDERS IN CHINESE MEDICINE Principal Investigator & Institution: Berman, Brian M.; Director; Family Medicine; University of Maryland Balt Prof School Baltimore, Md 21201 Timing: Fiscal Year 2003; Project Start 22-SEP-2003; Project End 31-MAR-2005 Summary: (provided by applicant): This application is for a Planning Grant for International Centers for Research on Complementary and Alternative Medicine (PICRC) in response to RFA AT-03-002. The goal of planning phase activities is to begin creation of the Functional Bowel Disorders and Traditional Chinese Medicine Research Group, with the participation of consortium members of three universities, The University of Maryland Center for Integrative Medicine, the Chinese University of Hong Kong, and the University of Illinois at Chicago Program for Collaborative Research in the Pharmaceutical Sciences. The consortium will develop a grant application for an International Center for Research on Complementary and Alternative Medicine (ICRC) to be submitted during the two-year planning phase, which will request funding to support three pilot projects related to irritable bowel syndrome and three cores: a Pharmacologic Core, a Data Management, Analysis, and Coordination Core, and an Administrative Core. The projects to be proposed will include 1) a rat model irritable bowel syndrome treatment trial using acupuncture and herbs, 2) a human pathophysiology pilot study on the effect of TCM on cerebral cortical activation and visceral sensation to rectal distension in IBS patients and non-IBS volunteers, and 3) Phase I and II clinical trials of TCM treatment in diarrhea-type IBS patients. Pilot studies in the animal model, standardization and authentication of the herbal preparation, and the techniques of human rectal distension in the functional MRI environment will be conducted in the planning phase to facilitate the projects to be proposed.

Project Title: GDNF IN THE ENTERIC NERVOUS SYSTEM Principal Investigator & Institution: Xia, Yun; Anesthesiology; Ohio State University 1960 Kenny Road Columbus, Oh 43210 Timing: Fiscal Year 2003; Project Start 30-SEP-2003; Project End 30-JUN-2008 Summary: (provided by applicant): This is a proposal for a KO8 Mentored Clinical Scientist Development Award for a physician scientist who holds an M.D. and Ph.D. in Physiology. The applicant aims to acquire the skills and conceptual knowledge necessary for conducting research on the nervous system of the digestive tract. This requires advanced training in electrophysiological methods, fluorescent immunohistochemistry and molecular biology to be obtained during the 5-year tenure of the Award. A lifelong career as a clinician scientist in an academic medical center is the applicant's goal. The proposed research is in the new and rapidly developing field of neurogastroenterology. The focus in this proposal on the enteric nervous system as a "brain-in-the-gut" addresses an important aspect of neurogastroenterology that is related to functional gastrointestinal disorders. Functional gastrointestinal disorders are believed to reflect neuropathic changes in the enteric nervous system that may be manifest as the irritable bowel syndrome (IBS), nonulcer dyspepsia or non-cardiac chest pain. The research is directed to understanding the role of glial derived neurotropic factor (GDNF) in the enteric nervous system. GDNF came to scientific and clinical life as a promising treatment to reverse neuronal degenerative changes in the brain that lead to Parkinson's disease. GDNF is a protective factor for neurons in the brain and peripheral nervous system. Mutations in the GDNF gene leads to Hirschsprung's disease in animals and humans. Parkinsonian patients in recombinant GDNF therapy trials experienced IBS-like diarrhea and cramping abdominal pain. Human trials showed evidence of a prokinetic action on gastrointestinal transit. The general scientific aim of the proposed work is to understand how GDNF works in the "brain-in-the-gut" to alter motility and secretory functions. The investigative work is based on results of pilot/feasibility studies that show significant actions of applied GDNF on both neuronal excitability and neurotransmission. Experimental protocols are designed to: 1) determine the action of GDNF on electrical and synaptic behavior of neurons in the enteric nervous system; 2) identify the morphological types of enteric neurons on which GDNF acts; 3) determine the localization and distribution of GDNF receptors in the enteric nervous system; 4) identify subtype/s of GDNF receptors that mediate its action on enteric neurons; 5) investigate factors that influence gene expression for the GDNF receptors in enteric neurons.

Project Title: GRADUAL EXPOSURE TREATMENT FOR IRRITABLE BOWEL SYNDROMEN Principal Investigator & Institution: Decola, Joseph P.; Psychology; University of California Los Angeles 10920 Wilshire Blvd., Suite 1200 Los Angeles, Ca 90024 Timing: Fiscal Year 2001; Project Start 01-APR-2001 Summary: The most commonly used non-medical treatment for Irritable Bowel Syndrome (IBS) is a combination of traditional stress management techniques and nonspecific cognitive therapy methods. This general approach is used to treat patients with divergent target symptoms (i.e., constipation and diarrhea). A limitation of this approach is that the treatment is not derived from a clear theoretical model that identifies a specific process underlying the disorder or treatment. The present study is based on a strong theoretical model that offers specific predictions and treatment

methods. The model assumes that hypervigilance and hypersensitivity to internal sensations in the gut are the critical perceptual mechanisms underlying IBS. These perceptual filters are the result of learning and conditioning processes and can be reversed with a cognitive-behavioral treatment that incorporates gradual exposure to internal sensations. Subject recruitment will be limited to IBS patients with diarrhea as the predominant symptom and the treatment will be implemented with a multiple baseline across subject design. The treatment will consist of several phases: education about the role of learning in the development of IBS symptoms; relaxation training; cognitive restructuring for overestimation and catastrophization errors; exposure to the feared internal sensations; and exposure to avoided situations. The goal of this treatment is to reverse the hypersensitivity and hyperviligance through gradual exposure to these stimuli. The broad objective of this research is to enhance the treatment for IBS and to test the predictions of this theoretical model. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: INTERGENERATIONAL TRANSMISSION OF ILLNESS BEHAVIOR Principal Investigator & Institution: Levy, Rona L.; Professor; None; University of Washington Seattle, Wa 98195 Timing: Fiscal Year 2001; Project Start 01-APR-1999; Project End 31-MAR-2003 Summary: U.S. health care costs may reach $2 trillion by the year 2000. Over- utilization is one of the major reasons given for rising health care costs. Illness behavior patterns, including health care utilization and disability days, run in families, and parental modeling and reinforcement have been proposed as likely mechanisms to explain family aggregation patterns. However, studies of parental reinforcement of illness behavior have been limited by retrospective reports from adults about their childhood experiences. The first aim of this study is to assess the way parents respond to their children's somatic complaints and to assess the relationship of parental reinforcement and modeling to various measures of illness behavior in their children. The long term goal is the development of an intervention model for prevention or reducing inappropriate illness behavior. A second aim is to determine whether the effects of modeling and reinforcement are independent of the psychosocial variables of family stress, competence, and parent and child psychological symptoms in determining child illness behavior. The proposed study will focus on gastrointestinal illness behavior in the children of adults with irritable bowel syndrome (IBS). Subjects will consist of children aged 8-16 years whose mothers have sought care for IBS from a defined managed care (HMO) population, control children whose mothers have sought care for asthma. All families will be randomly selected from the same population. For the IBS and non-IBS controls, questionnaire, interview and diary data will be obtained from parents and children on illness behavior, reinforcement, psychological symptoms, stress coping, and beliefs about illness, and school attendance data will be obtained from the schools. For all subjects, data will be collected from the HMO database on number, cost, type, and diagnosis for all parent and child health care visits. Data from the HMO and schools will be obtained prospectively for two years after entering the study and retrospectively for the two years prior to entering the study.

Project Title: MECHANISMS AND MODULATION OF VISCERAL PAIN Principal Investigator & Institution: Gebhart, Gerald F.; Professor and Chair; Pharmacology; University of Iowa Iowa City, Ia 52242 Timing: Fiscal Year 2001; Project Start 01-JUL-1983; Project End 30-JUN-2005 Summary: (adapted from applicant's abstract): Visceral pain, particularly visceral hyperalgesia such as is associated with the functional bowel disorders like irritable bowel syndrome, is poorly understood. Because functional bowel disorders are characterized by increased sensitivity to gastrointestinal stimulation, pain and discomfort, they represent a visceral hyperalgesia. Increasing interest over the past decade or more has contributed significant knowledge about visceral pain mechanisms. The current application proposes to build on this base of knowledge to develop and characterize models of visceral hyperalgesia that relate closely to clinical conditions typified by irritable bowel syndrome. Specifically, this proposal will focus on examination and characterization of peripheral contributions to the development and maintenance of visceral hyperalgesia. The first aim will be to develop appropriate models of irritable bowel syndrome and contrast those models with a model of colonic inflammation/colitis. It is hypothesized that changes in the excitability of visceral sensory fibers contribute significantly to development of visceral hyperalgesia and the second aim of this proposal will be in vivo electrophysiological examination of pelvic nerve afferent fiber excitability. Because increases in excitability of pelvic nerve sensory fibers must arise from changes in the function of ion channels or receptors in their cell bodies and terminals, the third aim of this proposal is to study the excitability of identified colon sensory neurons. These aims are a logical extension of the current project and will continue important investigations into the mechanisms of visceral hyperalgesia. The proposed experiments comprise a quantitative study of visceral hyperalgesia, pelvic nerve sensory afferent fibers and colon sensory neurons that will lead to better understanding of the mechanisms responsible for visceral hyperalgesia.

Project Title: MECHANISMS OF CHRONIC VISCERAL HYPERALGESIA Principal Investigator & Institution: Al-Chaer, Elie D.; Professor; Internal Medicine; University of Texas Medical Br Galveston 301 University Blvd Galveston, Tx 77555 Timing: Fiscal Year 2001; Project Start 05-APR-2001; Project End 31-MAR-2005 Summary: Visceral hyperalgesia is a hallmark of the irritable bowel syndrome (IBS), an extremely common disorder, affecting up to 15 percent of the US population with a major socioeconomic impact. Our understanding of the hyperalgesia in functional pain syndromes such as lBS lags behind our knowledge of the mechanisms of other types of visceral pain that are mechanically-induced or caused by inflammatory reactions mainly because of the lack of a valid animal model. Recently, it was shown that functional abdominal pain can be modeled in animals. Colon irritation (CI) in neonatal but not adult rats, can cause a long lasting visceral hyperalgesia that persists long after the initial injury has resolved. In this study, the central hypothesis is that persistent colonic hyperalgesia, residual to neonatal colon irritation, is associated with central neural sensitization maintained by an interactive exchange of information between the spinal cord and thalamus. HYPOTHESIS 1: There exists a postnatal window of time when

minimal colon irritation can induce permanent changes in the nervous system that leads to chronic visceral hyperalgesia. SPECIFIC AIM] will define this window of time in postnatal development using noxious mechanical distension or chemical irritation of the colon to cause chronic visceral hyperalgesia. HYPOTHESIS 2: The persistent visceral hyperalgesia residual to neonatal CI is maintained by central plastic changes in neuronal sensitivity. SPECIFIC AIM 2 will demonstrate with immunocytochemistry and electrophysiology, that the chronic visceral hyperalgesia is associated with neuronal sensitization in the spinal cord and the thalamus. HYPOTHESIS 3: The sensitization is maintained in part by neuronal mechanisms involving glutamatergic and peptidergic processes. SPECIFIC AIM 3 will determine if blockade of glutamate or neurokinin receptors by specific antagonists will reduce the central sensitization. HYPOTHESIS 4: The central sensitization is maintained by an intact dorsal column (DC) participating in a feed-forward dynamic exchange of information between the dorsal horn of the spinal cord and the thalamus. SPECIFIC AIM 4 will demonstrate, using electrophysiology and behavior studies, that the sensitization is mediated by an intact DC-thalamus communication that maintains thalamic sensitization and amplifies spinal neuronal sensitivity via descending pathways. The long-term objective of the proposed study is to define the neurophysiological correlates of chronic visceral hyperalgesia and hence to identify novel therapeutic targets for the relief of pain in patients with functional bowel disorders.

Project Title: MECHANOTRANSDUCTION IN INTESTINAL SMOOTH MUSCLE CELLS Principal Investigator & Institution: Farrugia, Gianrico; Mayo Clinic Rochester 200 1St St Sw Rochester, Mn 55905 Timing: Fiscal Year 2001; Project Start 01-SEP-1997; Project End 31-DEC-2002 Summary: Mechano-gated ion channels provide a mechanism for cells to respond directly to changes in their environment and are involved in several key cellular functions including cell division, regulation of volume, muscle tone and muscle.hypertrophy. Neurons, cardiac, and vascular smooth muscle cells have mechano-gated ion channels. However, the presence and significance of mechano-gated ion channels in gastrointestinal smooth muscle is unknown. The objective of this proposal is to establish the physiological importance of mechano-gated ion channels in single human and canine jejunal circular smooth muscle cells. The Preliminary data obtained by the PI suggest that membrane stretch, increase in cell volume, and cytoskeletal manipulation modulate the whole cell current in human and canine jejunal circular smooth muscle cells. Based on these preliminary data the working hypothesis of this proposal is that mechano-gated ion channels are present on smooth muscle cells and that activation of the channels results in changes in ionic flux and membrane potential, ultimately resulting in changes in intestinal contractility. There are three specific aims: (1) to determine if a change in shape or size of human and canine jejunal circular smooth muscle cells activates mechano-gated channels; (2) to determine which ion channel or channels underlies the increase in whole cell current evoked by a change in cell size or shape; and (3), to determine if regulation of mechano-gated ion channel open probability is dependent on the cellular cytoskeleton. The development of a dissociation technique for obtaining healthy human small intestinal smooth muscle cells by the PI will enable the use of patch clamp recordings and immunofluorescent techniques to address the three specific aims. The demonstration of mechano-gated ion channels in gastrointestinal smooth muscle will provide a novel pathway by which small intestinal

smooth muscle cells can directly and appropriately respond to changes in their environment. Activation of mechano-gated ion channels may be of physiological significance in the smooth muscle response to changes in intraluminal pressure in normal digestion, and of pathophysiological significance in inflammatory or obstructive diseases such as Crohn's disease and strictures and in irritable bowel syndrome where mechano-gated ion channels may be overexpressed.

Project Title: MEDIAL PAIN INPUTS TO MONKEY ANTERIOR CINGULATE CORTEX Principal Investigator & Institution: Vogt, Brent A.; Neuroscience and Physiology; Upstate Medical University Research Administration Syracuse, Ny 13210 Timing: Fiscal Year 2004; Project Start 01-DEC-2003; Project End 30-NOV-2008 Summary: (provided by applicant): Anterior cingulate cortex is the most frequently activated cortex in human pain studies and is comprised of perigenual and midcingulate regions. Nociceptive information passes through the midline and intralaminar thalamic nuclei, however, links between the spinothalamic tract and spinoreticulothalamic system to the midline nuclei has never been made directly to cingulate cortex. A case of irritable bowel syndrome with severe visceral pain shows alleviation of symptoms with psychotherapy and reduced midcingulate and increased anterior insular activity. Two hypotheses guide these studies: Functions of perigenual areas 32, 25, 24a-c and midcingulate areas 32' and 24a'-d are driven by different midline thalamic inputs and these nuclei conduct parallel circuits for nociception and stress. Each animal will receive horseradish peroxidase either in the spinal cord or dorsocaudal medullary reticular nucleus, and three fluorescent dextran amine retrograde tracers in contralateral cingulate and/or insular areas followed by reactions for 4 antibodies. Specific Aim #1 will evaluate the immunoarchitecture of the midline and dorsocaudal medullary nuclei with a neuron-specific antibody and antibodies for neurofilaments and calbindin. #2 will determine the projections of the midline nuclei to perigenual, midcingulate, and insular cortices with multiple fluorescent tracers that have the same uptake, transport, and signal properties. #3 will evaluate the topography of inputs to the midline nuclei with anterograde horseradish peroxidase following cervical spinal cord injections. #4 will assess the topography of inputs to the midline nuclei with horseradish peroxidase in the dorsocaudal medullary nucleus. #5 will evaluate overlap of dopamine-13 hydroxylase in each of the midline nuclei with inputs from spinothalamic and medullary nuclei to determine the overlap of nociceptive and stress circuits in the thalamus. These studies will provide the first evidence for differential projections of the midline thalamus to limbic cortex and the extent of spinothalamic, medullary, and locus coeruleus overlap in the medial thalamus and modulatation of sensory, affective, and motor domains of pain processing in anterior cingulate and insular cortices. The mechanisms of medial pain system processing will be identified and this will help interpret human imaging studies and assist in developing objective cdteria and therapies for treating the psychiatric consequences of chronic pain.

Timing: Fiscal Year 2003; Project Start 01-AUG-2003; Project End 31-JUL-2005 Summary: (provided by applicant): Risk factors for pancreatic cancer are not well established. The goal of this pilot study is to investigate the relation between medical history, medication use and pancreatic cancer in a case-control study based on medical record abstraction and electronic laboratory and pharmacy data. Our specific aims are: 1. To investigate the relation between medical conditions and pancreatic cancer risk, focusing on: a. Diabetes mellitus, including disease duration, therapy, and glycemic control. b. Pancreatic inflammation, including acute and chronic pancreatitis. c. History of peptic ulcer disease and/or infection with Helicobacter pylori (H. pylori). d. History of cholecystectomy and/or cholelithiasis. 2. To investigate the relation between the use of medications and pancreatic cancer, focusing on nonsteroidal anti-inflammatory drugs, cholesterol lowering agents including HMG-CoA reductase inhibitors and acid suppressive medications including histamine receptor antagonists and proton pump inhibitors. As a secondary specific aim we propose to examine additional medical conditions and medications in order to generate hypotheses for future studies of the epidemiology and prevention of pancreatic cancer. These include evaluation of medical conditions such as irritable bowel syndrome, allergies and asthma as well as medications including immunosuppressive medications and angiotensin converting enzyme inhibitors. To meet these specific aims we propose to conduct a case-control study of pancreatic cancer comprised of 250 newly diagnosed cases and 1,000 controls in the defined population of Group Health Cooperative, a large health maintenance organization. Data on prior medical conditions and medications will be collected through abstraction of traditional and computerized medical records, including electronic laboratory and pharmacy data. Study strengths include the availability of uniformly collected, long-term medical and pharmacy data and the availability of data on important covariates, including smoking. The proposed study will provide a unique opportunity to investigate the role of medical conditions and medications in pancreatic tumorigenesis and to generate new insights into the mechanisms that result in pancreatic cancer.

Project Title: MULTICENTER TRIAL OF FUNCTIONAL BOWEL DISORDERS Principal Investigator & Institution: Drossman, Douglas Arnold.; Medicine; University of North Carolina Chapel Hill Office of Sponsored Research Chapel Hill, Nc 27599 Timing: Fiscal Year 2001; Project Start 30-SEP-1995; Project End 31-AUG-2003 Summary: The primary aim of this study is to compare the efficacies of clinical treatments for the group of chronic, painful functional bowel disorders (FBD) that predominantly affect women. Secondary aims include 1) determination of demographic, psychosocial, physiologic and symptomatic predictors of clinical improvement and 2) analysis of significant relationships among physiologic markers of FBD, psychosocial status, symptoms and treatment effects. The Principal Investigator and his colleagues propose to compare cognitive-behavioral psychological treatment with antidepressant drug therapy (desipramine) and education/attention placebo in over 300 women. Interrelationships between psychological and physiological factors on the development, clinical expression and treatment of FBD have long been recognized, but this is the first large-scale study designed both to isolate therapeutic effects, and to investigate interactions among physiologic measures, psychologic and sociodemographic factors, severity of symptoms, and therapeutic improvement including quality of life. In the proposed plan of research, at least 300 female patients (aged 18- 65) with FBD (irritable bowel syndrome, painful constipation and/or functional abdominal pain) will be

Irritable Bowel Syndrome
enrolled in clinics at UNC-Chapel Hill and Toronto, Canada. A severity index will determine recruitment into the group of moderate FBD (200 patients) and severe FBD (100 patients). Each group will be randomized into the three treatment arms (cognitivebehavioral treatment, desipramine, and education/attention placebo), treated over a 12week period, and followed for one year. Outcome measures will include symptoms (standardized abdominal pain, stool form, and frequency) using diary cards, daily functional status (Sickness Impact Profile), depression (HAM-D), and psychological distress (SCL-90), physiological measures (enhanced rectal motility and visceralsensation), and health care use. Multivariate statistical methods with a hierarchical design will be applied to the data to assure maintenance of statistical power over multiple tests of overlapping groups. The results of this study may significantly improve an understanding of this complicated syndrome that lowers the quality of life and economic productivity of large numbers of women. The clinical impact of the study, in providing physicians with scientific evidence of the efficacy of treatments of FBD that are commonly used in practice, may be significant. This study may provide clinicians with predictors of success among types of FBD patients and types of therapy that will improve symptoms and quality of life and reduce the health care costs associated with this common syndrome, while improving patient-physician satisfaction.

Project Title: NEUROCHEMICAL MECHANISMS OF VISCERAL PAIN Principal Investigator & Institution: Traub, Richard J.; Associate Professor; Oral & Craniofacial Biol Scis; University of Maryland Balt Prof School Baltimore, Md 21201 Timing: Fiscal Year 2003; Project Start 01-AUG-1999; Project End 31-MAY-2007 Summary: (provided by applicant): Irritable Bowel Syndrome (IBS) is characterized by abdominal pain in the absence of pathology. Epidemiological studies further show IBS is reported most often in menstruating women compared to post-menopausal women or men suggesting gonadal hormones could be a contributing factor. It was recently hypothesized that the pain of IBS could result from sensitization of visceral afferent fibers or hyperexcitability of dorsal horn neurons. Recent data suggests a role for spinal NMDA receptors in processing noxious and innocuous visceral stimuli and NMDA receptors in the brain are modulated by estrogen. The long-term goal of this application is to examine the effects of estrogen on spinal NMDA receptor-mediated processing of noxious and innocuous colorectal stimuli. We hypothesize that estrogen increases activity at spinal NMDA receptors in the absence and presence of colonic inflammation leading to colorectal allodynia and hyperalgesia. This modulation may result from alterations in NMDA receptor subunit composition or second messenger mediated phosphorylation. Using our model of colorectal distention (CRD), we will test these hypotheses by examining the effects of estrogen replacement in ovariectomized rats on visceral sensory processing in the spinal cord in the absence and presence of colonic inflammation, in the following specific aims: 1) Determine the effects of estrogen on responses to transient innocuous, noxious and inflammatory colorectal stimuli. Behavioral, immunocytochemical and electrophysiological studies will test the hypothesis that estrogen facilitates responses to CRD in the absence and presence of colonic inflammation. 2) Characterize the effects of estrogen on subpopulations of visceroceptive projection neurons using retrograde tract tracing and immunocytochemical localization of Fos expression. This will test the hypothesis that estrogen alters the percentage and segmental distribution of supraspinal projection neurons that respond to CRD in the absence and presence of colonic inflammation. 3) Determine if NMDA receptor-mediated modulation of viscerosensory processing is

affected by ovariectomy and estrogen replacement. This will test the hypothesis that the modulation of responses to CRD by estrogen is due to altering activity at NMDA receptors. 4) Determine the mechanism(s) through which estrogen modulates CRDevoked NMDA receptor activity in the absence and presence of colonic inflammation. This will test the hypothesis that estrogen alters NMDA receptor subunit composition and/or modulates second messenger-mediated phosphorylation of tile NMDA receptor.

Project Title: NEUROIMMUNE MECHANISMS OF VISCERAL HYPERALGESIA Principal Investigator & Institution: Pezzone, Michael A.; Medicine; University of Pittsburgh at Pittsburgh 350 Thackeray Hall Pittsburgh, Pa 15260 Timing: Fiscal Year 2001; Project Start 15-APR-1999; Project End 31-JAN-2004 Summary: The applicant for this Mentored Clinical Scientist Development Award is currently completing a Fellowship in Gastroenterology and Hepatology at the University of Pittsburgh Medical Center. During his training to obtain combined M.D. and Ph.D. degrees under the mentorship of Bruce Rabin, M.D., Ph.D., the candidate investigated extensively the neural and neuroendocrine mechanisms of stressor-induced immune alterations int he rat, focusing specifically on stress-activated CNS pathways that may modulate lymphocyte function. In these studies, the candidate identified stress-activated neurons in the rat CNS by using c-FOS expression as a marker of neuronal stimulation following acute footshock and conditioned stress. To further his career in academic medicine and to further develop his expertise in neuro-immune interactions and stress, the candidate has designed this research proposal to assess the roles of stress and intestinal inflammation in the development of visceral hyperalgesia in the gut. This model of colonic inflammation (trinitrobenzenesulfonic acid in ethanol) appears to be propagated by cells of the immune system and is subsequently modulated by stress. Understanding the pathophysiologic roles of these factors in the sensitization of gastrointestinal afferents will help further provide important information regarding the etiology and clinical course (including relapse) of painful bowel disorders such as irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD). Methods encompassing intestinal electrophysiology, neuropharmacology, histology, and mast cell growth factors will be used to evaluate, in a hapten- induced model of colonic inflammation, the chemical dialog between afferent nerves and inflammatory/immune cells is likely to contribute to the sensitization of gastrointestinal afferents in pathological conditions such as IBS and IBD. This dialog may be modulated by activity in autonomic pathways to the gut and/or by chemicals released from the pituitary gland during stress. Combining these new skills with those previously acquired, the applicant will be well-suited to study a variety of gastrointestinal disease states in addition to characterization of the neuroimmune mechanisms of visceral hyperalgesia.

nervous system, the Interstitial Cells of Cajal (intestinal pacemaker cells), and sympathetic innervation to the gut. In addition, the principal investigator will use a recently described imaging technique (diolistic labeling) to examine intestinal smooth muscle, and perform functional motility analysis in mutant mice. The long-term objective of these experiments is to identify novel mutations that affect intestinal motility. These studies are important because defects in intestinal innervation and motility cause significant morbidity and mortality. Medical problems associated with abnormal intestinal motility include Hirschsprung's disease, intestinal pseudoobstruction, and irritable bowel syndrome.

Project Title: NK CELL ACTIVITY AND IBS ACROSS THE MENSTRUAL CYCLE Principal Investigator & Institution: Motzer, Sandra A.; Assistant Professor; Biobehavioral Nursing and Health Systems; University of Washington Seattle, Wa 98195 Timing: Fiscal Year 2001; Project Start 01-APR-2000; Project End 31-MAR-2003 Summary: The purpose of this study is to compare natural killer (NK) cell percentage and activity across the menstrual cycle in women with and without irritable bowel syndrome (IBS). NK cells are unique amongst immune cells because their percentage and activity vary in response to many emotional, cognitive and physiological stressor (e.g., anxiety, depression, perceived lack of personal control, bereavement, and exercise). Cognitive/emotional stressors are often experienced by persons with chronic health disturbances. Further, NK function many be amenable to change with interventions targeting distress in normal persons, ill persons, or their caregivers. This study will compare a sample of women with a chronic health disturbance Further, NK function may be amenable to change with interventions targeting distress in normal persons, ill persons, or their caregivers. This study will compare a sample of women with a chronic health disturbance, IBS, with control women without chronic gastrointestinal (GI) symptoms. Differences in physiological arousal and immune function will be examined within the context of menstrual cycle phase. This study is innovative in that it is designed to examine the relationship between stress-related psychological and physiological variables and immune function within the context of menstrual cycle phase in 2 groups of women, one symptomatic without an identified underlying inflammatory component but with evidence of physiological arousal (HPA axis and SNS activation) and another as control. Prior research by others has documented elevated stress hormone levels in women with IBS. Preliminary data suggest innate immune function differs in women with and without symptomatic IBS. Specific aims are to: 1) describe the levels of specific immune function markers across menstrual cycle phases, and test for cycle phase and group difference sin normally menstruating women with and without IBS; 2) extend and affirm the work of others by describing levels of stress and ovarian hormones, and self-report distress across 3 menstrual cycle phases, and by testing for cycle phase and group differences in these variables; and 3) examine the relationship of immune function to measures of physiological arousal, physical and psychological distress, and ovarian hormones during each menstrual cycle phase. Descriptive and correlational statistical and repeated measures ANOVA will be used in data analysis. If a relationship exists between chronic distress and NK cell function, there would be important clinical implications for identifying women at risk for experiencing chronic distress, and for developing and testing interventions targeting distress reduction in vulnerable populations.

Project Title: NON-ADDICTING CANNABINOID MEDICATIONS Principal Investigator & Institution: Malan, Thomas P.; Anesthesiology; University of Arizona P O Box 3308 Tucson, Az 857223308 Timing: Fiscal Year 2003; Project Start 01-AUG-2003; Project End 31-MAY-2006 Summary: (provided by applicant): As a physician, I see many patients with medical conditions for which adequate therapy is not available. CB2 cannabinoid receptorselective agonist medications may prove useful in treating some of these disease states. One is moderate-to-severe pain, where the use of opioid medications, the most effective therapy, is often limited due to concerns over addiction. In addition, opioids prescribed as analgesics are subject to diversion and abuse. We have shown that CB2 receptorselective agonists produce strong antinociceptive effects in animal models, suggesting that they may be useful as analgesic medications for humans. Unlike cannabinoids with agonist activity at CB1 receptors, CB2 receptor-selective agonists are predicted not to produce the rewarding properties associated with drug abuse, since CB2 receptors are not found in the CNS. By reducing the need for opioids, CB2 receptor-selective medications would diminish the problem of addiction with its severe individual and social costs. CB2 receptor-selective agonists, however, are likely to have important medical applications beyond analgesia. In this proposal, we hypothesize that CB2 receptor-selective agonists will be useful in the treatment of the prevalent and challenging problems of urinary incontinence; irritable bowel syndrome, inflammatory bowel disease and visceral hypersensitivity; and opioid resistant neuropathic pain. Our goal is to combine state-of-the-art chemistry and biology to develop CB2 receptorselective agonists as medications. Aim one will test the hypothesis that CB2 receptorselective agonists will have therapeutically desirable properties beyond analgesic effects. We will explore the activity of CB2 receptor-selective agonists in experimental models relevant to urinary incontinence; inflammatory bowel disease and other conditions associated with sensitization or increased activity of C-fibers. We will also test the hypothesis that CB2 receptor-selective agonists will not produce a withdrawal syndrome or provide reward. Aim two will use a lead optimization strategy to improve the medicinal properties of AM1241, our structural lead compound. This will be accomplished by a structure-activity relationship study involving the systematic manipulation of each of the molecule's pharmacophoric groups using drug design principles. Novel compounds will be evaluated for their affinity at and selectivity for CB2 cannabinoid receptors in vitro and for desired properties in vivo. The successful completion of these aims will provide physicians a therapeutic option that may provide relief for patients with difficult medical conditions and decrease the use of opioids, minimizing opportunities for abuse.

Project Title: NORADRENERGIC DYSFUNCTION--A MODEL OF FIBROMYALGIA PAIN Principal Investigator & Institution: Jasmin, Luc; Neurological Surgery; University of California San Francisco 500 Parnassus Ave San Francisco, Ca 94122 Timing: Fiscal Year 2001; Project Start 01-JUL-1999; Project End 30-JUN-2003 Summary: The goal of this project is to develop a rat model of fibromyalgia pain which could provide the basis for future research into this complex disease. The difficulty in finding an etiology for this painful condition is in part because fibromyalgia is not a discrete or unique disease, but patients also a display number of different symptoms in addition to the widespread tenderness, including fatigue, sleep disturbances, headaches,
50
Irritable Bowel Syndrome
gastrointestinal symptoms, etc. As such, fibromyalgia overlaps conditions such as Chronic Fatigue Syndrome, Irritable Bowel Syndrome, tension and migraine headaches. These conditions share several features, including a female predominance, initiation or exacerbation in response to several different types of "stressors", and response to similar types of pharmacologic and non-pharmacologic modalities (e.g. tricyclic drugs, aerobic exercise). A dysfunction of the noradrenergic system, the basis for the proposed model, presents a unifying explanation for many seemingly disparate findings in fibromyalgia by accounting for the neuroendocrine and autonomic abnormalities, in addition to the chronic pain. Our guiding hypothesis is that in fibromyalgia, chronically decreased noradrenergic input to the spinal cord facilitates substance P release and subsequent hyperalgesia (decreased threshold for pain). This hypothesis is based on both clinical evidence of decreased noradrenaline and increased substance P in the spinal cord of fibromyalgia patients, as well as evidence from basic research demonstrating that acute decreases in spinal noradrenaline allow for greater release of substance P and sustained hyperalgesic effects of this neurotransmitter. These alterations in turn result in greater expression and redistribution of the substance P receptor in the spinal cord, contributing to the chronicity of the hyperalgesia. In the female rat, we will apply a novel technique of selective immunolesion of brainstem noradrenergic input to nociceptive areas of the spinal cord. The first aim will test the hypothesis that lowered nociceptive thresholds in rats with decreased spinal noradrenaline depend on substance P neurotransmission. This hypothesis will be tested by determining the contribution of spinal SP neurotransmission in alterations of nociceptive behavioral and neuronal responses to noxious and innocuous stimuli. The second aim will test the hypothesis that chronically decreased spinal noradrenaline chronically increases basal levels, and facilitates evoked release of substance P, by measuring levels of substance P in the CSF, primary afferent neurons, and spinal cord, both basal and following noxious and innocuous stimulation. In the third aim, we will test the hypothesis that decreased spinal noradrenaline facilitates stimulus-induced increased expression and redistribution of the substance P receptor (NK1 receptor) in the spinal cord by measuring basal and noxious stimulus-induced alterations in the expression of this receptor.

Project Title: NOVEL DRUG DISCOVERY TOOLS FOR DEPRESSION AND ANXIETY Principal Investigator & Institution: Nanda, Steven A.; Promoter Neurosciences, Llc 505 S Rosa Rd, Ste 52 Madison, Wi 53719 Timing: Fiscal Year 2003; Project Start 01-AUG-2003; Project End 31-JAN-2004 Summary: (provided by applicant): Stress is a significant factor that can precipitate, exacerbate, and maintain psychopathology. The corticotropin-releasing factor (CRF) system has been implicated in mediating the stress response and linking it to psychopathology. Over-activity of the CRF system is implicated in depression, anxiety, and perhaps other stress-related disorders such as irritable bowel syndrome. Abundant preclinical evidence indicates that treatments targeting this system offer a promising approach for treating certain neuropsychiatric, as well as, other stress-related physical illnesses. Promoter Neuroscience (PNS) has developed intellectual property related to the promoter sequences of the CRF family of genes and is developing screening tools for drug discovery. PNS has demonstrated the feasibility of using cell cultures transiently transfected with CRF system promoter reporter constructs as high throughput screening tools. The proposed studies will further develop PNS's proprietary technologies and

help accelerate the discovery of compounds capable of altering expression of the CRF system. To improve this technology and to make a drug-screening tool relevant to humans, we will transfer our technology to human cortical neuronal cultures, which are derived from a brain region that naturally expresses CRF receptors and has been implicated in mediating the psychopathology. One set of cells will be transfected with constructs containing the human CRF receptor 2a (CRF2a) promoter driving expression of the Lucifer's reporter gene. Separate cortical neuronal cultures will be stably transfected with constructs containing the luciferase reporter gene under control of the human CRF receptor 1 (CRF1) promoter. Studies will characterize the basal levels of expression from the stably transfected cultures. To begin to explore potential new therapeutic approaches, expression from the stably transfected cultures will be monitored following treatment with compounds known to activate several different intracellular pathways. Activation of these intracellular pathways will lead to stimulation of transcription factors that bind to putative cis-regulatory elements identified within the CRF1 and CRF2a promoter regions. The stably transfected human cortical neuronal cultures will provide models relevant to human brain function that will provide PNS with the potential to discover new drugs that regulate CRF receptor expression.

Project Title: ORWH: SCOR ON SEX AND GENDER FACTORS AFFECTING WOMEN'S * Principal Investigator & Institution: Greenspan, Joel D.; Associate Professor; Basic Dental Sciences; University of Maryland Balt Prof School Baltimore, Md 21201 Timing: Fiscal Year 2002; Project Start 20-SEP-2002; Project End 31-AUG-2007 Summary: (provided by applicant): This multidisciplinary SCOR is devoted to the study of the mechanisms of chronic or persistent pain with specialized focus on 1) sex-related factors that influence pain, and 2) painful clinical conditions that demonstrate a high prevalence in women. The Center's research program is diverse, and ranges from molecular studies to systems physiology studies to clinical studies. Our working model is that research on pain has clearly shown that a person's sex is an important factor in determining their perception of, and response to, painful stimulation and pathological pain. Several physiological and psychological mechanisms have been proposed to account for these sex differences, yet many hypotheses remain to be adequately tested. This SCOR would direct its efforts to evaluating physiological models of sex-related pain differences, including the influence of gonadal hormones. Additionally, this Center would evaluate pathophysiological models of chronic pain conditions that are more prevalent in women, focusing on temporomandibular joint disorders (TMD) and the visceral pain associated with conditions such as irritable bowel syndrome (113S). This Center would facilitate the transfer of basic scientific knowledge to the study of persistent pain in humans, and ultimately to the development of new methods of diagnosing and treating these conditions in the general population. One clinical and two basic science projects constitute the scientific basis of the application. The two principal objectives of this SCOR are: 1) To elucidate the underlying mechanisms associated with sex differences in persistent pain of deep muscle and visceral origin. Human and animal studies will explore hypothesized physiological mechanisms of sex differences in pain, including opioid receptor expression, peripheral nociceptor sensitivity, CNS sensitization, and CNS ascending/descending modulation, as well as the influence of gonadal steroids on these mechanisms. All three projects address this objective. 2) To explore the neural basis of temporomandibular disorder (TMD) pain, with special

Irritable Bowel Syndrome
emphasis upon sex-related hypotheses. TMD is the major persistent orofacial pain condition of deep tissue origin. It shows a large prevalence in women of childbearing age. The pathophysiology of TMD is poorly understood, but several hypotheses based on sex-related factors have been proposed. Two of the proposed projects (#1and #3) direct efforts explicitly to evaluate such hypotheses. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: P2: SEX DIFFERENCES IN THE COLONIC RESPONSES TO STRESS: ROLE OF CRF PATHWAYS Principal Investigator & Institution: Tache, Yvette F.; Professor; University of California Los Angeles 10920 Wilshire Blvd., Suite 1200 Los Angeles, Ca 90024 Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-AUG-2007 Summary: Stress is implicated as the causative or complicating factor of symptoms of several diseases including altered bowel habits and visceral hyperalgesia in Irritable Bowel Syndrome (IBS) patients. Our previous work as well as other studies show that the activation of corticotropin-releasing factor (CRY) receptors mediates various stressors-induced alterations of gut motor function and that CRF1 receptor is mostly involved in the colonic response. Recent evidence also suggests a role of this pathway in stress-relatcd colonic hypersensitivity to colorectal distention. Despite the greater prevalence of stress-related IBS symptoms in women, most of the experimental knowledge of the effects and mechanisms of stress on gut motor alterations and visceral hyperalgesia derives from studies performed in male rodents. The overall goal of the proposal is to characterize the neuroanatomical and biochemical substrata underlying for sex-related differences in stress-induced colonic responses (motility and visceral pain) in rats. Based on presence of estrogen responsive elements on the CRF gene and its modulation by estrogen in the hypothalamus, we will test the hypothesis that estrogeninduced modulation of CRF signaling pathways contributes to the enhanced colonic responses of female rodents to stress. In the specific aim 1, we will build on our data preliminary data and characterizes sex-related differences in stress-induced colonic motor activation and visceral hyperalgesia using psychological and visceral stressors in model of IBS. We will assess with the newly developed CRF1 and CRF2 selective receptor antagonists the role of activation of CRF receptors in stress-related colonic responses in female rats and modulation by sex hormones. In specific aim 2, we will define the sex-related differential activation of brain, spinal and enteric circuitry induced by stress, particularly at neuronal sites involved in autonomic and pain modulation and known to express estrogen receptors using Fos expression as a marker of neuronal activation. Double labeling will be used to identify the presence of estrogen receptors and identified CRF and/or oxytocin and noradrenergic neurons. Specific Aim 3 will determine the modulation of CRF and CRF1 gene transcription by estrogen at specific sites involved in the colonic responses to stress. The regulation of rat and human CRF and CRF1 receptor promoter activity by estrogens will be further investigated in naive and transfected cells. These studies using functional, neuroanatomical, neurochemical and molecular approaches in rodent model will provide new insight on the interactions between estrogens and CRF pathways as it relates to the visceral response to stress and the underlying mechanisms at the levels of gene regulation and will have relevance to the pathophysiology of stress-related exacerbation of IBS.

Principal Investigator & Institution: Chang, Lin; University of California Los Angeles 10920 Wilshire Blvd., Suite 1200 Los Angeles, Ca 90024 Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-AUG-2007 Summary: Studies support a prominent role of stress in irritable bowel syndrome (IBS). The principal branches of the general stress response are the hypothalamic-pituitaryadrenal (HPA)axis and the sympathetic nervous system (SNS). The overall hypothesis of this Project is that females and males differ in their HPA axis responsiveness and SNS activation, particularly under stress conditions, and that these differences will help explain the greater vulnerability of females to develop chronic stress-related conditions such as IBS. Furthermore, these sex-related differences in the HPA and SNS are reflected in differences in colonic mucosal immune modulation which in turn relates to the higher prevalence of colonic visceral hypersensitivity in female IBS patients. We will study four subject groups: female IBS patients, male IBS patients, female controls and male controls. In Aim 1, we will test the hypothesis that under basal conditions, males have greater HPA (ACTH, cortisol) and general SNS (cardiosympathetic and sympathoadrenal) activity but females may have greater SNS activity to the pelvic organs. Specifically, we will compare HPA responsiveness in males and females using HPA axis challenge tests, biomathematical modeling analysis to characterize the diurnal rhythm of ACTH and cortisol, and estimate chronically enhanced SNS output to the colon by measuring tissue NE levels and alpha 2-receptor density in colonic biopsies. In Aim 2, we will test the hypothesis that under stress conditions, males show greater general measures of plasma HPA (ACTH, cortisol) and SNS activity (cardiosympathetic, catecholamines and skin conductance) responses to a visceral stressor (flexible sigmoidoscopy) and a psychological stressor (Trier social stress test) compared to females. In Aim 3, we :will test the hypothesis that symptomatic IBS patients have: altered plasma and mucosal cytokine production which differ in females and males and are related to sex-related differences in visceral pain perception. We will measure plasma and colonic mucosal cytokine markers, and perceptual responses to rectal balloon distension to determine if visceral sensitivity is associated with mucosal and plasma immune markers. The combination of experimental approaches should improve our understanding of the sex-related differences in stress response mechanisms underlying functional pain syndromes.

Project Title: P4: SEX DIFFERENCES IN CRF, NORADRENERGIC FUNCTION AND OXYTOCIN IN CATS WITH IC Principal Investigator & Institution: Buffington, Charles A.; Professor; University of California Los Angeles 10920 Wilshire Blvd., Suite 1200 Los Angeles, Ca 90024 Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-AUG-2007 Summary: The long-term goal is to exploit a naturally occurring bladder disease in domestic cats (Feline Interstitial Cystitis - FIC) to gain a better understanding of a painful bladder disorder in humans called interstitial cystitis (IC), and by extension other pelvic pain syndromes. This is because many patients with IC also have IBS and other neurovisceral disorders that predominantly affect women, and appear to be exacerbated by stress. The studies proposed here are designed to further investigate the causes of these neurological alterations in controlled studies of cats diagnosed with IC and healthy cats. The studies are needed to elucidate the significance of the underlying
54
Irritable Bowel Syndrome
neurological abnormalities present in human patients with IC. They also are intended to guide the choice of subsequent studies toward the primary systems involved in IC, with the eventual goal of identifying rational treatments of IC in human beings. The overall objective of this proposal is to test the hypothesis that interactions between CRF, sex hormones and the alpha-2 adrenoceptor (alpha2-AR) play a role in the sex difference in stress-responsiveness of cats with FIC. The rationale for the proposal is based on 1) clinical evidence that females are more prone to develop IC than males (intact males in cats), 2) the gap in knowledge in factors that may account for such sex differences due to the paucity of experimental data in this field, 3) evidence from our recent studies pointing to a role of alpha2-AR dysfunction in cats with IC, and 4) existing evidence that urothelial and alpha2-AR function can be modulated by testosterone, estrogen, and oxytocin. By studying a natural occurring animal model of IC which shares many features with a rat model of IBS, and with the respective human patient populations, we will be able to assess the role of sex hormones on the expression of these diseases.

Project Title: POPULATION BASED TWIN STUDY OF CHRONIC FATIGUE SYNDROMEN Principal Investigator & Institution: Sullivan, Patrick F.; Associate Professor; University of Washington Seattle, Wa 98195 Timing: Fiscal Year 2001 Summary: Despite considerable research, fundamental questions about CFS-like illness remain at best partially answered. These questions include its definition, validity, the degree to which it results from genetic versus environmental factors, and the nature of the substantial comorbidity observed with other conditions. The overarching aim of this Project is to shed light on a number of basic questions about CFS via a large populationbased classical twin study. First, we will screen approximately 13,000 same-sex twin pairs who are members of the Mid-Atlantic Twin Registry for the lifetime presence of CFS-like illness (and several overlapping conditions such as fibromyalgia and major depression). Second, all twins who screen positive and a subset of twins who screen negative will be directly and blindly interviewed. The interviews will collect information about CFS symptoms, psychiatric disorders, stress life events, and medical history, and medical history. We will obtain additional standardized medical data via the subject's physician(s). Third, all screening, direct interview and medical data will be independently reviewed by three of the study investigators to determine the certainty than an individual meets criteria for "presumptive CFS" plus approximations of the Centers for Disease Control, British, and Australian CFS case definitions. Obtaining these unique data will allow us to address a set of critical questions regarding CFS-like illness. First, using the direct interview data will allow us to address a set of critical questions regarding CFS-like illness. First, using the direct interview data, we will use multivariate techniques to derive and empirical typology of prolonged fatigue and to assess how this typology compares to the major CFS case definitions to answer the question: "Is there a point of rarity that distinguishes the common symptom of fatigue from case definitions of CFS"? Next, we will quantify the role of genetic predisposition and environmental sources of variation from different definitions of CFS-like illness. This will allow us to address 2 important questions. Because the degree to which a complex and idiopathic condition is heritable is an important validator, we can address the question: "Do these definitions yield similar or different estimates of heritability?" In addition, examining the extent to which liability to CFS- like illness is due to additive genetic, shared environmental, and individual-specific environmental precipitating

55
effects will yield glimpses into the fundamental nature of CFS. Finally, using multivariate twin analyses, we address the question: "To what extent to the genetic and environmental sources of variation of these other conditions overlap with CFS?"

Project Title: PRESYNAPTIC MECHANISMS IN THE INTESTINE Principal Investigator & Institution: Galligan, James J.; Professor; Pharmacology and Toxicology; Michigan State University 301 Administration Bldg East Lansing, Mi 48824 Timing: Fiscal Year 2001; Project Start 01-SEP-2000; Project End 30-JUN-2004 Summary: Presynaptic mechanisms are an important means for neurotransmitters, hormones, paracrine substances and drugs to modulate the activity of myenteric nerves and gut motility. Despite the clear importance of presynaptic mechanisms in regulating neurotransmission in the myenteric plexus, little is known about the details of these mechanisms. The proposed studies are designed to characterize these mechanisms. Electrophysiological methods will be used to study excitatory synaptic transmission between myenteric neurons in acutely isolated preparations of guinea pig intestine and between guinea pig myenteric neurons maintained under tissue culture conditions. These studies will investigate the contributions of acetylcholine (ACh) acting at nicotinic cholinergic receptors and ATP acting at P2X purine receptors, to fast excitatory synaptic potentials (fEPSPs) during long trains of stimulation. As nicotinic receptors desensitize quickly, it is anticipated that ACh will be the predominate transmitter early while ATP will predominate later in the train of activity. Presynaptic mechanisms controlling the release of these two important transmitters will also be investigated. These studies will focus on channels which provide the calcium needed for transmitter release and the presynaptic receptors which facilitate their release. The facilitatory effects of 5-HT4 receptor activation on fEPSPs mediated by ACh and ATP will be investigated. In addition, these studies will investigate the contribution of 5-HT3 and 5-HT4 receptors to excitation of enteric sensory nerve terminals. The role of presynaptic nicotinic acetylcholine receptors (nAChRs) in controlling the release of the slow synaptic transmitters, substance P/neurokinin A will also be investigated. These latter studies will attempt to establish that there are presynaptic nAChRs on the terminals of sensory neurons and that ACh released from sensory neurons facilitates SP/NKA release and enhances slow excitatory synaptic transmission. There are many disorders of gut motility which have their basis either directly or indirectly in alterations in enteric neurotransmission. These disorders include gastroesophageal reflux disease, the irritable bowel syndrome and chronic intestinal pseudo-obstruction. It is anticipated that these studies will provide new insights into mechanisms of synaptic transmission in the gut which could lead to the development of new and effect drug treatments for motility disorders.

Project Title: PSYCHOPHYSIOLOGY OF IRRITABLE BOWEL SYNDROMEN Principal Investigator & Institution: Whitehead, William E.; Professor of Medicine; Medicine; University of North Carolina Chapel Hill Office of Sponsored Research Chapel Hill, Nc 27599 Timing: Fiscal Year 2001; Project Start 01-JUL-1993; Project End 30-NOV-2002 Summary: The irritable bowel syndrome (IBS), which is characterized by abdominal pain and altered bowel habits, is the most common gastrointestinal disorder, affecting 9.4 percent of the population. Fifty to 60 percent of IBS patients report pain at
56
Irritable Bowel Syndrome
abnormally low volumes of rectal distention, suggesting that visceral hyperalgesia may be the mechanism for IBS. A cognitive behavioral model is presented which accounts for increased pain sensitivity in IBS by two hypotheses: (1) Two cognitive traits--selective attention on gastrointestinal sensations and attribution of disease significance to these sensations--are the mechanisms by which stress and other factors influence pain perception. (2) Childhood social learning in the form of increased attention for somatic complaints and modeling of sick role behavior by parents, is the most important determinant of selective attention and disease attribution. The differential recall of previously memorized words, depending on their content, will be used to develop a test for selective attention. Words describing gastrointestinal sensations plus control words describing respiratory sensations and neutral words will be tested for a prior probability of recall by healthy subjects. Then IBS patients, patients with lactose malabsorption (an enzyme deficiency producing chronic gastrointestinal symptoms similar to IBS), patients with asthma, and healthy controls will memorize these words, and 15 minutes later will be tested for recall. Other techniques for assessing selective attention which will be compared to the recall task are the Stroop Color Test and recognition of words in the above categories presented briefly by a tachistoscope. The test of disease attribution will be developed by presenting the same gastrointestinal and respiratory sensations and asking subjects to rate whether they could be symptoms of disease. After developing valid and reliable measures, new samples of IBS patients, lactose intolerant patients, and controls will complete these tests of reinforcement and modeling of gastrointestinalrelated sick role behavior and tests of rectal distention pain thresholds. A subsequent study will determine whether experimental stress increases pain sensitivity and progressive muscle relaxation decreases pain sensitivity in IBS patients, and whether these psychological influences on perceptions are associated with changes in selective attention to gastrointestinal sensations.

Project Title: RECURRENT ABDOMINAL PAIN IN CHILDREN Principal Investigator & Institution: Shulman, Robert; Pediatrics; Baylor College of Medicine 1 Baylor Plaza Houston, Tx 77030 Timing: Fiscal Year 2002; Project Start 01-AUG-2002; Project End 30-APR-2007 Summary: (provided by applicant) Ten to 17 percent of children between the ages of 4 and 16 years meet the criteria for recurrent abdominal pain (RAP) a condition that accounts for at least 5 percent of all pediatric office visits and often leads to significant disability (e.g., school absence). From 30-60 percent of children with RAP will go on to experience similar pain as adults leading to the suggestion that RAP and irritable bowel syndrome (IBS) may be the same syndrome at different developmental stages. Similar to IBS, 20-68 percent of children reporting abdominal pain also experience alterations in bowel patterns (constipation and/or diarrhea). Although the cause(s) of RAP (as well as IBS) are unknown, factors contributing to the symptom experience, including health care seeking, are likely to include both physiological and psychosocial. The relationships among physiologic abnormalities, psychological makeup, and parental responses/behaviors in RAP are largely unexplored (undefined). To study the contributions of these sets of factors and their potential interplay, we propose to compare three groups of children: those with RAP who are referred to tertiary medical attention (RAP-GI); who have RAP but do not seek medical attention beyond their pediatrician (RAP-Ped); and those who do not have RAP symptoms (Controls). Our Specific Aims are to describe and compare among these children (ages 7-10): 1) GI symptoms (abdominal pain and bowel patterns) and functional disability (pain

interfering with activity, school absences) using retrospective and prospective symptom measures; 2) autonomic nervous system function (spectral and non-spectral analysis of heart rate variability and urine catecholamines); 3) child and parent pain coping skills, parent modeling and reinforcement of illness behavior; and 4) psychological distress (anxiety, depression, and somatization). Children will be recruited from pediatric practices in Houston. This proposed interdisciplinary study will be the first in children to examine concurrently both physiologic and psychosocial factors related to RAP, and its functional consequences, and to compare these to a sample of children with RAP who do not seek tertiary medical attention. Because so many children with RAP are identified as having IBS when they reach adulthood, this study may provide insight into the developmental progression of this disorder. These data could be used to develop guidelines for use by health care providers to intervene early with children who have this common complaint in order to prevent health care seeking behavior with its attendant financial and emotional cost.

Project Title: REGULATION OF IMMUNOSUPPRESSIVE MOLECULES IN IBD Principal Investigator & Institution: Jobin, Christian; Assistant Professor; Medicine; University of North Carolina Chapel Hill Office of Sponsored Research Chapel Hill, Nc 27599 Timing: Fiscal Year 2003; Project Start 30-SEP-1993; Project End 30-JUN-2008 Summary: (provided by applicant): A single layer of intestinal epithelial cells (IEC) protects the host from the toxic luminal environment. These cells are in close proximity with lamina propria immune cells and likely communicate with each other by direct contact and/or secretion of soluble mediators. Interestingly, the mucosa of the distal ileum and colon is constantly exposed to a complex microbial flora, yet no pathological inflammation occurs in normal hosts. This suggests that IEC gene expression must be tightly regulated to avoid overreaction to ubiquitous luminal bacterial products, yet be able to transiently respond to environmental pathogens. Although the repertoire of proinflammatory molecules synthesized by IEC has been identified, little is known about how these cells regulate coordinated expression and suppression of these genes. In addition, the intracellular signaling pathways associated with IEC gene expression are still poorly understood. Finally, the kinetics and distribution of NF-kappaB-activated cells during the course of an intestinal inflammatory process is currently unclear, much less during treatment intervention. We have shown that the NF-kappaB pathway regulates expression of a number of proinflammatory cytokines and adhesion molecules in IEC. Interestingly, native IEC and most transformed colonic cell lines show a unique IkappaBa phosphorylation and degradation process that distinguishes these cells from other cell lineages. Our hypothesis is that normal lEC have a unique NF-kappaB signaling pathway which buffers their cellular responses to the aggressive luminal environment. This hypothesis will be tested by addressing the following SPECIFIC AIMS: 1) Dissect the unique IkappaB/NF-kappaB signal transduction in transformed and native IEC following stimulation with environmentally relevant cytokines and commensal bacteria and explore mechanisms of suppression of this pathway by TGFbeta 2) Determine the physiological role of NF-kappaB in acute and chronic intestinal inflammation and tissue repair by using kappaB-green fluorescence protein transgenic mice with experimental colitis in combination with selective inhibition of the NF-kappaB pathway. Our ultimate goal is to prevent the onset and relapse of inflammatory bowel diseases (IBD) by manipulating key regulatory signaling proteins involved in central inflammatory pathways.

Project Title: RISK FACTORS FOR ENDOMETRIOSIS Principal Investigator & Institution: Hunter, David J.; Director; Epidemiology; Harvard University (Sch of Public Hlth) Public Health Campus Boston, Ma 02460 Timing: Fiscal Year 2001; Project Start 03-AUG-2001; Project End 31-JUL-2003 Summary: (provided by applicant): Endometriosis, the third leading cause of gynecologic hospitalization in the United States, remains one of the most enigmatic gynecologic pathologies. Endometriosis is defined as the presence of endometrial tissue outside of the uterine cavity. These implants respond to the hormonal cues of the menstrual cycle and "bleed" as they would in the uterus. The consequence is the development of adhesions, scarring, and painful inflammation. Signs and symptoms include dysmenorrhea, dyspareunia, infertility, dysuria, and irritable bowel syndrome.The effects of the disease can be physically and mentally debilitating with frequent misdiagnoses and poor treatment options. Its prevalence among U.S. women has been estimated to be approximately 10%, [the] time from onset of symptoms to laparoscopically confirmed diagnosis is estimated to average between 6 and 11 years. To date, the etiology of endometriosis remains unknown and few epidemiologic studies exist. Using data on 2,690 laparoscopically confirmed incident cases of endometriosis collected from the Nurses' Health Study II, an ongoing, prospective cohort study that began in 1989, the applicant proposes a study to assess the following hypotheses: a) Women with menstrual characteristics of younger age at menarche, longer time to menstrual regularity, or shorter menstrual cycle length are at higher risk of endometriosis. b) Women with a low waist-to-hip ratio are a higher risk of endometriosis. c) Women with a higher body mass index at age 18 are at lower risk of endometriosis. d)Women who were born with a greater birthweight are at higher risk of endometriosis. All analyses will control for other known and suggested risk factors for endometriosis such as oral contraceptive use and cigarette smoking. The applicant will have more than 90% power to evaluate the above hypotheses. These analyses will be the first prospective data with adequate power to evaluate this important and understudied cause of morbidity among premenopausal women.

Project Title: SELECTIVE CRF ANTAGONISTS FOR BOWEL DISORDERS Principal Investigator & Institution: Grigoriadis, Dimitri E.; Neurocrine Biosciences, Inc. 10555 Science Center Dr San Diego, Ca 921211100 Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 01-MAY-2003 Summary: (Applicant's abstract): Corticotropin releasing factor (CRF) controls the anterior pituitary secretion of adrenocorticotropin and other propiomelanocortin products. CRF also coordinates the endocrine, behavioral and autonomic responses to stress. The long-term objectives of this proposal are to establish that selective corticotrophin releasing factor receptor subtype 1 (CRF1) antagonists will have therapeutic implications in irritable bowel syndrome (IBS) characterized by altered bowel movement and visceral hypersensitivity. The specific aims will be: 1) to demonstrate specific tissue localization of CRF1 receptors in the colon; 2) to identify and synthesize centrally acting vs. peripherally acting high affinity CRF1 receptor nonpeptide antagonists; and 3) to examine both centrally acting and peripherally acting CRF1 antagonists in models of stress-related colonic motor stimulation and visceral hypersensitivity in rodents for potential utility in IBS. This will be achieved using novel

Based on the co-morbidity between anxiety/depression and IBS and stress-related onset or enhanced IBS symptomatology, these pre-clinical studies will provide the key information needed to pursue a novel therapeutic approach for IBS using Neurocrine CRF1 receptor antagonists and to further develop this therapeutic approach in Phase II studies.

Project Title: SEX DIFFERENCES IN VISCERAL PAIN: INFLUENCE OF GONADAL STEROIDS Principal Investigator & Institution: Murhpy, Anne Z.; Univ of Maryland, Baltimore Baltimore, Md Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-AUG-2007 Summary: Irritable bowel syndrome (IBS), a common gastrointestinal disorder characterized by abdominal pain and a change in bowel habits, will affect up to 20% of the general population. Epidemiological studies have established that females are 2-5x more likely to suffer from IBS in comparison to males. A defining characteristic of IBS is severe gastrointestinal pain. Surprisingly, while an extensive body of research has been conducted examining the neural mechanisms underlying visceral pain, these studies have been conducted exclusively in males. Thus, it is not known how visceroceptive information is processed within the CNS of females. Similarly, the impact of gonadal steroids on visceral pain is also not known. Behavioral studies in Aim 1 will characterize the sex differences and influence of gonadal steroids on visceral pain. Our preliminary data indicate that there are profound sex differences in the visceral motor reflex, an indicator of visceral pain following noxious colorectal distention. Our data further show that the sexually dimorphic response to noxious visceral stimulation is estrogen dependent. Anatomical studies proposed in Aim 2 will test the hypothesis that sex differences in the organization and activation of the spinoparabrachial circuit provide the anatomical substrate for the dimorphic response to noxious visceral stimulation. Studies using acute somatic stimuli have reported that morphine produces a significantly greater degree of analgesia in males versus females, and our preliminary studies indicate that morphine alleviation of visceral pain is also sexually dimorphic. Studies proposed in Aim 3 will test the hypothesis that morphine produces a significantly greater degree of analgesia in males in comparison to females in a model of visceral pain. Immunocytochemical and molecular studies proposed in Aim 4 will test the hypothesis that opioid receptor expression within the lumbosacral spinal cord is sexually dimorphic. The influence of gonadal steroids on opioid receptor expression will also be examined. Together, these studies will begin to elucidate the neural mechanisms underlying sex differences in visceral pain. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: SLOWING OF TRANSIT - THE THIRD ENTERIC FUNCTION OF 5HT Principal Investigator & Institution: Lin, Henry C.; Director Gastrointestinal Motility Progr; Cedars-Sinai Medical Center Box 48750, 8700 Beverly Blvd Los Angeles, Ca 90048 Timing: Fiscal Year 2003; Project Start 01-SEP-2003; Project End 31-AUG-2006 Summary: (provided by applicant): In order to optimize nutrition, the movement of a meal through the small intestine must be precisely controlled to ensure that there is

Irritable Bowel Syndrome
adequate time to complete the time-demanding steps of digestion and absorption. Abdominal pain, nausea, bloating, diarrhea and malnutrition are the consequences of impaired control of intestinal transit. After a fat-containing meal, inhibitory feedback mechanisms are activated by the proximal and distal small intestine as the jejunal and ileal brake, respectively. In contrast to this focus of the postprandial gut to slow transit, much of the research efforts over the past 100 years have been directed at the peristaltic reflex, which is responsible for the acceleration of intestinal transit and are known to be mediated by 5-HT. Currently, two roles of enteric 5-HT have been established: the triggering of the peristaltic and mucosal secretory reflexes via intrinsic primary afferent neurons and gut-to-CNS and gut-to-pancreas communications via extrinsic sensory nerves. We have recently found a third role of enteric 5-HT. Specifically, 5-HT is also involved in the slowing of transit by fat via a 5-HT3 pathway that is dependent on 5-HT transmission via myenteric neurons. In this proposal, we will test our overall hypothesis that slowing of intestinal transit by fat depends on primary afferent nerves, betaadrenergic pathway and 5-HT transmission via myenteric neurons, which in turn activates opioid neurons, that slow transit. We will test the hypotheses using pharmacologic and physiologic approaches. The results of these studies will help us to refine our hypotheses so that we can test the neuroanatomic components of this pathway using immunohistochemistry. We have developed a collaboration with 2 leading neuroscientists who will provide this project with additional expertise in immunohistochemistry. In addition, to test the role of a novel beta-adrenergic system in the slowing of intestinal transit by fat, we have developed a multi-disciplinary team approach by including a cardiologist experienced in the 13- adrenergic system. The PI has a track record of success in bench-to-bedside translational research in the area of nutrient control of intestinal transit. His experience includes the discovery of a novel, nutrient-based strategy to slow intestinal transit. This application will bring this new treatment back to basic research so that we can understand the neural pathways that underpin the slowing response to fat. The hypotheses to be tested in this project will expand our understanding of a new role for enteric 5-HT which may explain conditions such as irritable bowel syndrome and provide better understanding of the effects of drugs that are directed at 5-HT pathways. In addition, by investigating the mediators of the control of intestinal transit, we will gain knowledge that can be used to control the movement of a meal through the small intestine and, in turn, reduce symptoms and improve nutrition.

Project Title: SPATIAL AND TEMPORAL CHARACTERISTICS OF CENTRAL PAIN SE Principal Investigator & Institution: Mauderli, Andre P.; Prosthodontics; University of Florida Gainesville, Fl 32611 Timing: Fiscal Year 2002; Project Start 01-JUL-2002; Project End 31-MAY-2007 Summary: (provided by the applicant): Prolonged pain appears to have the potential to modulate its own intensity through positive and negative feedback (central sensitization by pain, pain inhibition by pain). If the feedback is positive, the result is a vicious pain cycle and a progressive increase in pain sensitivity. Increased pain sensitivity means that a given stimulus is perceived as more painful (hyperalgesia), or - in more extreme cases - that a previously non-painful stimulus becomes painful (allodynia). The vicious cycle may lead to sensitization beyond the topographical boundaries of the original pain, and thus it may render remote body regions more pain-prone. The result may be a snowball effect of progressive expansion of the painful area. There is evidence suggesting that the

61
vicious cycle may be a pathophysiological factor in certain chronic pain diseases, including fibromyalgia syndrome (FMS), myofascial pain syndrome (MPS), and irritable bowel syndrome (IBS). This research is guided by 4 questions: 1) Does the intensity and duration of a persistent pain have an effect on how pain sensitivity changes over time? 2) Does the sensitizing effect of pain signals reach beyond the topographical location of the original pain focus? 3) Is it possible to interrupt the vicious pain cycle and allow the sensitized state to return to normal by temporarily silencing the local pain focus that presumably started the cycle? 4) Does the maintenance of the sensitized state depend on central NMDA receptor function, molecular constituents known to play a role in temporal integration of pain stimuli and other memory systems? The subjects in this study will be asked to rate pain intensities by setting the slider on an electronic visual analog scale. Novel methodology will be used for probing the temporal and spatial response properties of central pain modulation with experimental pain with prolonged series of thermal pulses. The effect of silencing clinical pain foci with transdermally delivered local anesthetics on thermallyinduced sensitization will be studied. The importance of NMDA receptor systems in the maintenance of a sensitized state will be assessed by measuring pain sensitization properties before and after pharmacologically blocking them.

Project Title: STRUCTURE FUNCTION RELATIONSHIP OF MUSCARINIC TOXIN MT-7 Principal Investigator & Institution: Baksi, Krishna; Universidad Central Del Caribe Bayamon, Pr 009606032 Timing: Fiscal Year 2002; Project Start 01-AUG-1994; Project End 31-DEC-2005 Summary: Muscarinic acetylcholine receptors (mAChRs) are coupled to G-proteins and activate different second messengers and ion channels. Currently, there are five subtypes of mAChRs (M1 to M5) which are differentially distributed throughout the body. mAChRs are involved in a variety of disorders such as irritable bowel syndrome, asthma, glaucoma, cardiac arrhythmia, Parkinson's disease (PD), and Alzheimer's disease (AD). To date, the study of functions and characterization of subtypes of mAChRs are hampered due to lack of highly selective agonists and antagonists. Several toxins which recognize the mAChRs have been purified and sequenced from the venom of mamba snakes of the genus Dendroaspis. The sequences of the toxins are homologous, but their mode of action and selectivity for mAChR subtypes are different. For example, MT-7 is specific only for M1 receptors, whereas MT-3 toxin shows high affinity for M4 receptors, and low affinity for M1 receptors. The structure- activity relationship of MT-7 toxin, therefore, needed to establish the essential amino acid residues responsible for its binding to the M1 receptor to display its functions clearly. Biologically active recombinant MT-7 (rMT-7) toxin is available for such studies. The hypothesis of this proposal is that the functional site of MT-7 toxin requires multiple amino acid residues studies. The hypothesis of this proposal is that the functional site of MT-7 toxin requires multiple amino acid residues which are present in all the three loops of the toxin for its subtype specificity as well as for its action as antagonist. I, therefore propose to study the interaction of MT-7 toxin to M1 receptor, and the Specific Aims of my proposal are. SPECIFIC AIM 1: Production of MT7/MT3 chimeras and MT7M analogues. SPECIFIC AIM 2: Structure function relationship. SPECIFIC AIM 3: The mode of interaction of MT7/MT3chimeras/MT-7 analogues with M1 receptors. The completion of this study will lead us to establish the critical amino acid residues responsible for MT-7 toxin's binding to its receptor, and will also establish the specific

amino acid residues responsible for MT-7 toxin's subtype specificity. The results will help to design therapeutic agents for different disorders involving mAChRs. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: THE EFFICACY OF REIKI IN THE TREATMENT OF FIBROMYALGIA Principal Investigator & Institution: Assefi, Nassim P.; Women's Health Specialist; Medicine; University of Washington Seattle, Wa 98195 Timing: Fiscal Year 2002; Project Start 15-APR-2002; Project End 28-FEB-2004 Summary: (provided by applicant): Fibromyalgia (FM), one of the most common rheumatologic diagnoses, is a condition of unknown etiology characterized by widespread muscle pain and stiffness, accompanied by a variety of other symptoms including sleep disturbance, headaches, irritable bowel syndrome, and psychological distress. Treatment is generally unsatisfactory and most randomized, controlled treatment trials have been unable to demonstrate a sustained effective intervention. Thus, it is not surprising that the vast majority of FM patients have tried complementary and alternative medicine (CAM) therapies. Reiki is a form of energy medicine in which practitioners reportedly access universal life energy to heal patients, either by direct contact at specific hand positions or from a distance. A vast body of anecdotal literature as well as 2 randomized controlled trials suggest that Reiki may be an effective treatment for FM, appearing to relieve pain and improve psychological well being. In addition, it appears to have no adverse effects and can eventually be self-administered, making it a low-risk, low-cost, potentially patient-empowering intervention. This study will investigate the efficacy of Reiki in the treatment of FM. 100 Reiki-naive FM patients will be recruited from a chronic fatigue referral clinic, and will undergo an 8-week, biweekly (16 treatments) trial. Patients will be randomized into 2 Reiki groups (directcontact and distant Reiki) and 2 control (sham and placebo) groups. The sham Reiki practitioners will be professional actors who resemble the true Reiki practitioners but have no experience with health care or healing arts and are taught to mimic the Reiki Masters' verbal and physical interactions with the patients, while distracting whatever healing intention they may possess by doing mental arithmetic. The specific aims of this study are: 1) to evaluate the short and long-term efficacy and safety of an 8-week placebo-controlled randomized trial of both direct-contact and distant Reiki in the treatment of FM; 2) establish carefully constructed control groups for their feasibility and scientific usefulness for future trials of Reiki and other types of energy medicine; and 3) to collect pilot data for larger trials on the mechanism, safety, and duration of clinical and subjective effects of Reiki. Patients will be assessed at enrollment, 4 and 8 weeks during treatment and 12 weeks post-treatment. Our primary outcomes will be patient global assessment, subjective pain and mean number of tender points. Secondary outcomes will include pain threshold, sleep, fatigue, and psychological indicators. This pilot study could potentially impact the clinical care of the estimated 6 million Americans with FM, and shape the design of future larger, randomized, placebocontrolled trials of Reiki and other energy therapies.

Summary: (provided by applicant) Irritable Bowel Syndrome (IBS) is the most common of the functional gastrointestinal disorders with primary symptoms of chronic abdominal pain or discomfort associated with altered bowel habits. IBS is characterized by stress-related symptom exacerbations and a high co-morbidity with affective disorders, in particular, anxiety. The current proposal is based on a disease model of IBS that emphasizes enhanced responsiveness and conditioning of stress and fear circuits in the central nervous system, and associated hypervigilance, stress-induced hyperalgesia, and altered autonomic responses to visceral sensation. Based on this model and the highly successful exposure treatments now used for anxiety disorders, we have designed and successfully piloted a unique cognitive behavioral treatment (CBT) for IBS. Traditional CBT treatments focus on decreasing general stress responses and increasing coping skills for life stress, and have shown only modest efficacy in IBS. We hypothesize that IBS symptoms can be more effectively treated by specifically changing responses to visceral sensations through decreasing interoceptive conditioned responses, and directing attention away from visceral stimuli. If our hypotheses are correct, we expect to see greater symptom improvements as well as normalization of altered physiological responses following this new CBT approach. We propose to address the following specific aims: 1) Do subjective outcomes differ between the two cognitive behavioral interventions with and without interoceptive exposure and directed attention, and an attention control treatment? 2) Are differential treatment responses accompanied by changes in perceptual and autonomic responses to visceral stimuli? And 3) Are differential treatment responses accompanied by normalization of altered regional brain activation in response to visceral stimuli? In separate studies we will compare CBT with interoceptive exposure and directed attention to tradition CBT (and a control condition) on outcome measures of symptom reduction, beliefs, visceral sensitivity (pain, discomfort, and fear responses to balloon distension), and central responses to visceral stimulation using functional magnetic resonance imaging (fMRI).

Project Title: WOMEN'S HEALTH AND FUNCTIONAL VISCERAL DISORDERS CENTER Principal Investigator & Institution: Mayer, Emeran A.; Microbiology and Immunology; University of California Los Angeles 10920 Wilshire Blvd., Suite 1200 Los Angeles, Ca 90024 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-AUG-2007 Summary: (provided by applicant): The Women's Health and Functional Visceral Disorders Center is composed of a cohesive group of clinical investigators and basic scientists with strong independent grant-supported research programs in the interactions between the nervous system and the viscera, with special emphasis on stress neurobiology, sex differences and chronic functional disorders. The main focus of the Center is the identification of sex-related factors that play a role in the development, clinical manifestation and treatment response of two common visceral pain syndromes, e.g. Irritable Bowel Syndrome (IBS) and Interstitial Cystitis (IC). Both disorders are common, occur more commonly in females, appear to show sex differences in treatment responses and cause significant morbidity and impairment in quality of life. The Center has two clinical and two basic science Projects, which closely interdigitate and overlap in terms of thematic, experimental approach and hypotheses. Thus, while the clinical Projects study sex differences in central stress circuit activation and peripheral outputs of these circuits in human patients with IBS and IC, the two basic Projects study animal models of both disorders. State of the art technology ranging from molecular biological

approaches to functional brain imaging techniques will be used to address the following specific aims in the four Projects: 1. Sex Differences in Central Stress Circuit Responsiveness in IBS and IC patients 2. Sex differences in the colonic responses to stress: Role of CRF pathways 3. Sex differences in neuroendocrine and immunologic responses in IBS 4. Sex differences in CRF, noradrenergic function and oxytocin in cats with IC. To facilitate the research, the Center has an Administrative Core and a Scientific Core (Neuroendocrine Measures) and will take advantage of existing NIH-funded core and service facilities on campus, including the CURE: Digestive Diseases Research Center, the UCLA Brain Mapping Center and the GCRC. The Center provides an optimal environment for cooperation and collaboration among its investigators, who already have had a major impact on the field individually. Thus, the synergy expected from the Center promises to have an even larger impact upon expanded research into a highly prevalent, but inadequately treated area of women's health.

With PubMed Central, NCBI is taking the lead in preservation and maintenance of open access to electronic literature, just as NLM has done for decades with printed biomedical literature. PubMed Central aims to become a world-class library of the digital age. 5 The value of PubMed Central, in addition to its role as an archive, lies in the availability of data from diverse sources stored in a common format in a single repository. Many journals already have online publishing operations, and there is a growing tendency to publish material online only, to the exclusion of print. 6 PubMed was developed by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM) at the National Institutes of Health (NIH). The PubMed database was developed in conjunction with publishers of biomedical literature as a search tool for accessing literature citations and linking to full-text

CHAPTER 2. SYNDROME
NUTRITION
AND
IRRITABLE
BOWEL
Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and irritable bowel syndrome.
Finding Nutrition Studies on Irritable Bowel Syndrome The National Institutes of Health’s Office of Dietary Supplements (ODS) offers a searchable bibliographic database called the IBIDS (International Bibliographic Information on Dietary Supplements; National Institutes of Health, Building 31, Room 1B29, 31 Center Drive, MSC 2086, Bethesda, Maryland 20892-2086, Tel: 301-435-2920, Fax: 301-480-1845, E-mail:
[email protected]). The IBIDS contains over 460,000 scientific citations and summaries about dietary supplements and nutrition as well as references to published international, scientific literature on dietary supplements such as vitamins, minerals, and botanicals.7 The IBIDS includes references and citations to both human and animal research studies. As a service of the ODS, access to the IBIDS database is available free of charge at the following Web address: http://ods.od.nih.gov/databases/ibids.html. After entering the search area, you have three choices: (1) IBIDS Consumer Database, (2) Full IBIDS Database, or (3) Peer Reviewed Citations Only. Now that you have selected a database, click on the “Advanced” tab. An advanced search allows you to retrieve up to 100 fully explained references in a comprehensive format. Type “irritable bowel syndrome” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.
7 Adapted from http://ods.od.nih.gov. IBIDS is produced by the Office of Dietary Supplements (ODS) at the National Institutes of Health to assist the public, healthcare providers, educators, and researchers in locating credible, scientific information on dietary supplements. IBIDS was developed and will be maintained through an interagency partnership with the Food and Nutrition Information Center of the National Agricultural Library, U.S. Department of Agriculture.

Treatment of Functional Bowel Disorders Condition(s): Irritable Bowel Syndrome; Constipation; Abdominal Pain; Functional Colonic Diseases Study Status: This study is completed. Sponsor(s): National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) Purpose - Excerpt: The primary purpose for this study is to compare clinical treatments for patients with functional bowel disorders (irritable bowel syndrome, abdominal pain, painful constipation) in women. We also plan to: 1) determine what clinical features (medical or psychological) determine which patients will improve to these treatments, and 2) understand if there are any physiological features that relate to improvement in symptoms and response to the treatments. We will compare a psychological treatment (cognitive-behavioral therapy - CBT) with education/attention placebo, and an antidepressant drug (desipramine) with a pill placebo. This is the first large-scale study designed to determine the therapeutic effects of these methods, and to also determine interactions among physiologic measures, psychologic and sociodemographic factors, severity of symptoms, and therapeutic improvement including quality of life. Phase(s): Phase III Study Type: Interventional Contact(s): see Web site below Web Site: http://clinicaltrials.gov/ct/show/NCT00006157
Keeping Current on Clinical Trials The U.S. National Institutes of Health, through the National Library of Medicine, has developed ClinicalTrials.gov to provide current information about clinical research across the broadest number of diseases and conditions. The site was launched in February 2000 and currently contains approximately 5,700 clinical studies in over 59,000 locations worldwide, with most studies being conducted in the United States. ClinicalTrials.gov receives about 2 million hits per month and hosts approximately 5,400 visitors daily. To access this database, simply go to the Web site at http://www.clinicaltrials.gov/ and search by “irritable bowel syndrome” (or synonyms). While ClinicalTrials.gov is the most comprehensive listing of NIH-supported clinical trials available, not all trials are in the database. The database is updated regularly, so clinical

CHAPTER 6. PATENTS ON IRRITABLE BOWEL SYNDROME Overview Patents can be physical innovations (e.g. chemicals, pharmaceuticals, medical equipment) or processes (e.g. treatments or diagnostic procedures). The United States Patent and Trademark Office defines a patent as a grant of a property right to the inventor, issued by the Patent and Trademark Office.9 Patents, therefore, are intellectual property. For the United States, the term of a new patent is 20 years from the date when the patent application was filed. If the inventor wishes to receive economic benefits, it is likely that the invention will become commercially available within 20 years of the initial filing. It is important to understand, therefore, that an inventor’s patent does not indicate that a product or service is or will be commercially available. The patent implies only that the inventor has “the right to exclude others from making, using, offering for sale, or selling” the invention in the United States. While this relates to U.S. patents, similar rules govern foreign patents. In this chapter, we show you how to locate information on patents and their inventors. If you find a patent that is particularly interesting to you, contact the inventor or the assignee for further information. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical patents that use the generic term “irritable bowel syndrome” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on irritable bowel syndrome, we have not necessarily excluded non-medical patents in this bibliography.
Patents on Irritable Bowel Syndrome By performing a patent search focusing on irritable bowel syndrome, you can obtain information such as the title of the invention, the names of the inventor(s), the assignee(s) or the company that owns or controls the patent, a short abstract that summarizes the patent, and a few excerpts from the description of the patent. The abstract of a patent tends to be more technical in nature, while the description is often written for the public. Full patent descriptions contain much more information than is presented here (e.g. claims, references, figures, diagrams, etc.). We will tell you how to obtain this information later in the chapter. 9Adapted

Excerpt(s): The present invention relates to orthostatic lavage solutions or colonic evacuants for cleansing the gastrointestinal tract, or for the treatment of bowel diseases and/or disorders. The advent of colonoscopy brought with it the need for a simplified, routine bowel cleansing protocol or product to achieve a clean colonic mucosa required by the colonoscopist to detect even small lesions in the bowel, e.g., small polyps. Similar requirements exist for colonic surgery. In the early days of colonoscopy, during the late 1970's, numerous protocols for bowel cleansing were designed by individual bowel surgeons and gastroenterologists to satisfy the requirements of their particular practices. Such protocols included the use of fasting in combination with various purgatives such as Epsom salts or osmotic agents plus enemas. Though, when complex protocols were followed strictly they often achieved their effect and resulted in a clean bowel. However, the protocols were invariably complex and required on average three days of cleansing which made them unpleasant and unacceptable. Furthermore, they were often dangerous because they caused marked fluid and electrolyte shifts in body compartments and on rare occasions predisposed to arrythmias, hypertension and in fact demise of the patient.

Excerpt(s): The present invention relates to arylcycloalkane carboxylic esters having pharmacological properties, and to processes for their preparation. The invention also relates to pharmaceutical compositions containing arylcycloalkane carboxylic esters, methods of treating disorders related to urinary incontinence and irritable bowel syndrome (IBS), respectively, by administering an arylcycloalkane carboxylic ester, as well as methods for the manufacture of pharmaceutical compositions for treating disorders related to urinary incontinence and irritable bowel syndrome (IBS), respectively. A number of arylcycloalkane carboxylic esters, including arylcyclopropane, arylcyclobutane, arylcyclopentane and arylcyclohexane carboxylic acid esters, are known to possess anticholinergic activity. Some of them have a pronounced spasmolytic or anticonvulsant activity and have therefore been proposed to be used as substitutes for atropine in the treatment of sarin poisoning (sarin is an organophosphorous anticholinesterase agent acting as a nerve gas). Other activities related to that type of compounds are antipsychotic, anti-ischemic, anti-stroke and antidementia. Specific arylcyclopropane carboxylic esters having anticholinergic activities are, for example, described in Beres, J. A., et al., J. Pa. Acad. Sci. (1992), 66(1), 2; U.S. Pat.

Method and apparatus for diagnosis of irritable bowel syndrome Inventor(s): Craine; Brian L. (Fairfax, CA) Assignee(s): Western Research Company, Inc. (Tucson, AZ) Patent Number: 6,228,040 Date filed: July 28, 1999 Abstract: A protocol for the recording of bowel sounds, a computerized algorithm for recognizing the start and stop time of bowel sounds in the digital sound recordings, metrics that can be calculated from the start and stop times and limits of these metrics which can be used to categorize individuals with respect to medical conditions which effect the gastrointestinal tract. The use of these methods and values allows for the diagnosis of certain gastrointestinal syndromes or diseases with a high degree of accuracy in a manner not previously possible. Excerpt(s): The invention relates to using a computerized analysis of bowel sounds recorded using an electronic sound input device to diagnose gastrointestinal complaints of pain, bloating, or alteration of bowel habits, with emphasis on the diagnosis of irritable bowel syndrome. Irritable bowel syndrome is characterized by bowel irregularity (constipation and/or diarrhea), gaseous distention and abdominal pain. Irritable bowel syndrome is the most common gastrointestinal complaint for which patients seek medical care, accounting for 30 to 50 percent of the gastrointestinal complaints that bring patients to a physician. Various studies indicate that patients with irritable bowel syndrome constitute a large portion of a typical family physician's practice and account for more than 25% of all gastrointestinal referrals. Irritable bowel
138 Irritable Bowel Syndrome
syndrome is listed as a primary diagnosis in about 96,000 patients per year treated in nonfederal hospitals, and the disorder was considered a secondary diagnosis in another 85,000 patients. Most patients with gastrointestinal complaints are subjected to a battery of laboratory studies. These usually include sigmoidoscopy, complete blood count, erythrocyte sedimentation rate, serum electrolytes, liver function tests, urinalysis, and stool examination for occult blood and parasites. For a patient with chronic or recurring symptoms, endoscopy or radiographic contrast evaluations can be performed (but should not be repeated unless there is objective evidence of a change in the clinical condition, such as blood in the stool). In western societies, irritable bowel syndrome occurs twice as often in women as in men. About half of the patients are first seen for this condition before they reach 35 years of age. Various studies indicate that almost half of the patients are between the ages of 35 and 49, although symptoms usually begin much earlier and are likely to continue throughout life. The true prevalence of irritable bowel syndrome may be reflected in several non-patient surveys in which as much as 20 percent of the general population reported symptoms consistent with this disorder. The majority of these people do not seek medical assistance, although it is possible that their symptoms could be alleviated through education, simple methods of stress reduction, and dietary changes.

Method and composition for treating irritable bowel syndrome using low doses of opioid receptor antagonists Inventor(s): Crain; Stanley M. (Leonia, NJ), Fleischner; Gerald M. (Chappaqua, NY), Shen; Ke-fei (Flushing, NY) Assignee(s): Albert Einstein College of Medicine of Yeshiva University (Bronx, NY) Patent Number: 6,194,382 Date filed: March 3, 1999 Abstract: This invention relates to a method for eating a subject with irritable bowel syndrome ("IBS") which comprises long-term administration of an opioid receptor antagonist at an appropriately low dose which will selectively antagonize excitatory opioid receptor functions, but not inhibitory opioid receptor functions, in myenteric neurons in the intestinal tract as well as in neurons of the central nervous system ("CNS"). The administration of the opioid receptor antagonist at a low dose enhances the potency of the inhibitory effects of endogenous opioid peptides present in the intestinal tract and the CNS, thereby reducing abdominal pain and stool frequency resulting from abnormally supersensitized excitatory opioid receptor functions. The invention also relates to a composition for treating a subject with IBS, which comprises an effective dose of an opioid receptor antagonist, and a pharmaceutically acceptable carrier. Excerpt(s): This invention relates to a method for treating a subject with irritable bowel syndrome ("IBS") which comprises administering a low dose of an opioid receptor antagonist to the subject. Specifically, this invention relates to a method for treating a subject with IBS by the long-term administration of an opioid receptor antagonist at an appropriately low dose which will selectively antagonize excitatory opioid receptor functions, but not inhibitory opioid receptor functions, in myenteric neurons in the intestinal tract as well as in neurons of the central nervous system ("CNS").

abnormally supersensitized excitatory opioid receptor functions. The invention also relates to a composition for treating a subject with IBS, which comprises an effective dose of an opioid receptor antagonist, and a pharmaceutically acceptable carrier. Irritable bowel syndrome is a functional bowel disorder in which abdominal pain is associated with defecation or a change in bowel habit. IBS has elements of an intestinal motility disorder, a visceral sensation disorder, and a central nervous disorder. While the symptoms of IBS have a physiological basis, no physiological mechanism unique to IBS has been identified. Rather, the same mechanisms that cause occasional abdominal discomfort in healthy individuals operate to produce the symptoms of IBS. The symptoms of IBS are therefore a product of quantitative differences in the motor reactivity of the intestinal tract, and increased sensitivity to stimuli or spontaneous contractions. Due to a lack of readily identifiable structural or biochemical abnormalities in this syndrome, the medical community has developed a consensus definition and criteria, known as the Rome criteria, to aid in diagnosis of IBS. According to the Rome criteria, IBS is indicated by abdominal pain or discomfort which is (1) relieved by defection and/or (2) associated with a change in frequency or consistency of stools, plus two or more of the following: altered stool frequency, altered stool form, altered stool passage, passage of mucus, and bloating or feeling of abdominal distention (Dalton, C. and Drossman, D. A., Am Fam Physician 1997 55(3):875-880). Thus, a hallmark of IBS is abdominal pain that is relieved by defecation, and which is associated with a change in the consistency or frequency of stools. IBS may be diarrhea-predominant, constipationpredominant, or an alternating combination of both. Web site: http://www.delphion.com/details?pn=US06194382__ •
Method for alleviation of lower gastrointestinal disorders in a human patient Inventor(s): Dave; Bhavin (262 Pine Valley Dr., Dover, DE 19904), Rubin; Walter (1708 Riverview Rd., Gladwyne, PA 19035) Assignee(s): none reported Patent Number: 6,156,771 Date filed: May 21, 1998 Abstract: A method of alleviating a lower GI symptom in a human patient afflicted with a lower GI disorder and a method of treating a human patient afflicted with a lower GI disorder, including, for example, a patient afflicted with irritable bowel syndrome or a patient afflicted with functional diarrhea, are provided. Each of these methods comprises inhibiting gastric secretion by the patient, such as by administering to the patient a pharmaceutical preparation comprising an effective amount of an inhibitor of gastric secretion. Excerpt(s): The field of the invention is alleviation of lower gastrointestinal (GI) disorders in a human patient and alleviation of lower GI symptoms associated with such disorders. Between about 5% and about 10% of the U.S. population suffers from chronic diarrhea for which an organic cause cannot be identified (Camilleri et al., 1977, Aliment Pharmacol Ther. 11:3-15; Talley et al., 1991, Gastroenterology 101:927-934). The diarrhea may be persistent or may alternate with periods of normal bowel habit or with periods of constipation. Chronic diarrhea which is not accompanied by abdominal. pain and which is not attributable to an organic cause is referred to as "functional diarrhea" (FD) or "chronic idiopathic diarrhea" (Drossman et al., 1997, Gastroenterology 112:21202137; Hasler et al., 1995, In: Textbook of Gastroenterology, 2nd ed., Yamada, Ed., J. B. Lippincott Co., Philadelphia, pp. 1832-1855; Camilleri et al., supra; Drossman et al., 1994,

The functional Gastrointestinal disorders: Diagnosis, Pathophysiology, and Treatment, Degnon and Associates, McLean, Va.; Thompson et al., 1992, Gastroenterol. Intl. 5:7591). Chronic diarrhea which is associated with abdominal pain and which is not attributable to an organic cause is referred to as "irritable bowel syndrome with a diarrhea predominance" (IBS; Hasler et al., supra; American Gastroenterological Association, 1997, Gastroenterol. 112:2118-2119; Drossman et al., 1997, Gastroenterol. 112:2120-2137; Camilleri et al., supra). Postprandial urgency or postprandial accentuation of lower GI symptoms are common manifestations of both IBS and FD. Patients afflicted with either IBS or FD frequently experience an urgency to defecate after eating, and sometimes attribute this urgency to the ingestion of particular foods other than lactose. Furthermore, some of these patients associate exacerbation of their symptoms with emotional stress. These symptoms have led investigators of IBS and FD to believe that abnormal physiological factors, psychological factors, or both, may be associated with IBS and FD (Drossman et al., supra; Hasler et al., supra; Camilleri et al., supra; Drossman et al., supra; Drossman et al., supra; O'Brien et al., 1996, Gastroenterol. Clin. N. Am. 25:147-162; Bazzocchi et al., 1991, Gastroenterology 101:1298-1306; Choi et al., 1997, Am. J. Gastroenterol. 92:297-306; Aggarwal et al., 1994, Gastroenterology 106:945-950; Quigley, 1996, Gastroenterol. Clin. N. Am. 25:113-145; Schmidt et al., 1996, Scand. J.

Am. 25:21-34). No effective therapy has been established for the chronic diarrhea or the postprandial urgency associated with either IBS or FD (Drossman et al., 1997, supra; Hasler et al., supra; Camilleri et al., supra; Drossman et al., 1994, supra; Thompson et al., supra; Klein, 1988 Gastroenterology 95:232-241).

Method of screening for compounds that bind P2x receptor Inventor(s): Buell; Gary N (Geneva, CH), Valera; Soledad (Geneva, CH) Assignee(s): Glaxo Group Limited (Greenford, GB) Patent Number: 6,194,162 Date filed: July 30, 1999 Abstract: The P.sub.2X receptor of ATP has been cloned and expressed by recombinant DNA technology, so the receptor can be prepared free from other ATP receptors. The P.sub.2X receptor enables antibodies to be prepared and is useful in screening compounds for use in a variety of diseases and conditions, including epilepsy, cognition, emesis, pain (especially migraine), asthma, peripheral vascular disease, hypertension, diseases of the immune system, irritable bowel syndrome and premature ejaculation. Excerpt(s): This invention relate to the P.sub.2X -purinoceptor, its preparation and uses. The P.sub.2X -purinoceptor is a ligand-gated ion channel; that is, the receptor itself forms an ion channel which opens when extracellular adenosine 5'-triphosphate (ATP) binds to the receptor. There are five other classes of neurotransmitter receptors (nicotinic acetylcholine, glutamate, glycine, GABA.sub.A and 5-HT.sub.3); these form a structurally related superfamily of ligand-gated ion channels (Barnard, Trends Biochem. Sci. 17, 368-374, (1992)). The P.sub.2X -receptor now identifies a new family of this type of receptor. The unique structure of this receptor, the widespread distribution of this receptor throughout the body, and the numerous physiological roles this receptor may play, make it an important protein that can be used to identify new, therapeutically effective, compounds for the treatment of a number of pathological states. In 1929 the eminent physiologist Szent-Gyorgyi described powerful cardiovascular actions of extracellular purine nucleosides (e.g. adenosine) and nucleotides (e.g. ATP) (Drury & Szent-Gyorgyi, J. Physiol. 68 213-237 (1929)), but it was not until 1972 that pharmacological evidence was provided to suggest the existence of distinct receptors for extracellular ATP (ie. that recognise ATP but not adenosine) (Burnstock, Pharmacological Reviews 21 509-581 (1972)). The seminal and subsequent work on this area by Burnstock and colleagues was largely unaccepted throughout the 1970s and early 1980s until the development of a range of relatively selective ligands and techniques for directly measuring ATP release overwhelmingly substantiated Burnstock's hypothesis (Barnard et al., Trends Pharmacol. Sci. 15 67-70 (1994)). In the past four or five years, unequivocal evidence for the role of ATP as a neurotransmitter has been provided for sympathetic control of blood flow to the intestine and smooth muscle tone (contractility) in genitourinary tissue such as vas deferens, bladder and ureter (Barnard et al. (loc. cit.) and Evans & Surprenant, Brit. J. Pharmacol. 106 242-249 (1992)). Substantial indirect evidence also exists for the role of ATP as a neurotransmitter in a number of distinct neurones in the spinal cord, autonomic ganglia and certain nuclei in the central nervous system (Bean, Trends Pharmacol. Sci. 15 67-70 (1992), Evans et al., Nature 357, 503-505 (1992) and Edwards et al., Nature 359 144-147 (1992)). Web site: http://www.delphion.com/details?pn=US06194162__

Assays, e.g., screening tests, to identify PAK modulating agents or agents that modulate muscle contraction are also provided. Excerpt(s): This invention relates to methods for modulating muscle contraction, and particularly, to methods for modulating smooth muscle contraction in the absence of calcium, and for increasing the calcium sensitivity of both smooth muscle and cardiac muscle. p21-activated kinase (PAK) proteins are serine/threonine protein kinases homologous to the yeast Ste20 kinase. Several distinct members of the PAK family have been identified in mammalian cells, including PAK1, PAK2, PAK3, and PAK65. It has been shown that PAK proteins can be activated by the small Rho-family GTP-binding proteins Cdc42 and Rac1, which are known to regulate assembly of the actin cytoskeletal structure (Zhang et al. 1995, J. Biol. Chem. 270:23934-36). Smooth muscle, in contrast to striated muscle (cardiac and skeletal muscle), is capable of maintaining force at low levels of intracellular calcium. One member of the small Rho-family of GTP-binding proteins, RhoA, has been shown recently to induce smooth muscle contraction independently of calcium. RhoA activates a serinet reonine kinase named ROK (RhoA associated kinase or p160ROK) which can cause smooth muscle calcium-independent contraction. Cardiac muscle, on the other hand, requires increased levels of intracellular calcium for contraction. Web site: http://www.delphion.com/details?pn=US06248549__

N-substituted pyrrolidine derivatives and process for preparing the same Inventor(s): Ando; Naoki (Nogi-machi, JP), Hoshino; Masato (Oyama, JP), Kobayashi; Fumiyoshi (Oyama, JP), Miyachi; Hiroyuki (Kazo, JP) Assignee(s): Kyorin Pharmaceutical Co., Ltd. (Tokyo, JP) Patent Number: 6,071,950 Date filed: June 2, 1999 Abstract: Novel N-substituted pyrrolidine derivatives having a highly selective and potent antagonism against smooth muscle muscarine receptors and being useful for the treatment of irritable bowel syndrome and the like, characterized by being represented by general formula (1) wherein R represents a hydrogen atom, a halogen atom, or a lower alkoxy group and a process for preparing the same. Excerpt(s): The present invention relates to novel N-substituted pyrrolidine derivatives having a highly selective and potent antagonism against smooth muscle muscarine receptors rather than cardiac muscarine receptors and being useful for the treatment of altered smooth muscle motility and tone, such as irritable bowel syndrome, diverticulosis, urinary incontinence, esophageal achalasia and chronic obstructive airway disease, and process for preparing the same. As one of the therapeutic drugs for the irritable bowel syndrome, the anticholinergic agent has been used, but it brings no sufficient therapeutic effect due to, in part, deficit of tissue selectivity. Also, while compounds that was reported to have a selective antagonism against smooth muscle muscarine receptors are disclosed (Japanese Unexamined Patent Publication Nos. Hei 2282360 and Hei 7-149640, these compounds also do not sufficiently solve the adverse effect such as mydriasis. Moreover, these compounds have diphenylalkyl moiety linked to carbon atom of the pyrrolidine ring, making them different from the structure of the inventive compounds, in which it links to the nitrogen atom of the pyrrolidine ring. The invention is to provide novel N-substituted pyrrolidine derivatives having a highly selective and potent antagonism against smooth muscle muscarine receptors and being useful for the treatment of irritable bowel syndrome and the like.

(Tokyo, JP) Patent Number: 6,528,504 Date filed: July 9, 2001 Abstract: The present invention provides (R)-5,11-dihydro-5-[1-(4methoxyphenethyl)piperidine-2-ylmethyl]dibenzo[b, e][1,4]oxazepine, (R)-5,11-dihydro5-[1-(4-dimethylaminophenethyl)piperidine-2-ylmethyl]dibe nzo[b,e][1,4]oxazepine, compounds analogous to them and pharmaceutical compositions containing such a compound. These compounds are useful for treating or preventing abnormal motor functions of gastrointestinal tracts, particularly irritable bowel syndrome. Excerpt(s): The present invention relates to 5,11-dihydrodibenzo [b,e][1,4]oxazepine derivatives antagonistic to calcium channel and useful for treating or preventing abnormal motor functions of gastrointestinal tracts, particularly intestinal diseases such

as irritable bowel syndrome, stereoisomers thereof, pharmacologically acceptable salts thereof or hydrates thereof, and pharmaceutical compositions containing them as active ingredients. It is disclosed in, for example, European Patent No. 0404359A1 that 5,11dihydrodibenzo[b,e][1,4]thiazepine derivatives are usable as calcium channel antagonists selectively effective on gastrointestinal tracts. Quinn, P. et al., Brit. J. Pharmacol. 1994, 112 (Suppl.), Abst 573P and Wallis R. M. et al. Brit. J. Pharmacol. 1994, 112 (Suppl.), Abst. 574P disclose that (S)-5-[[1-(4-methoxyphenyl)ethyl]pyrrolidine-2ylmethyl]-5,11-dihydrodiben zo[b,e][1,4]thiazepine maleate which is one of derivatives of those compounds has effects similar to the effects of them. Further, International Patent No. 9733885A1 discloses 5-(2-pyrrolidinyl-methyl)-5,11-dihydrodibenzo [b,e][1,4]oxazepine derivatives as medicines for improving motor insufficiency of gastrointestinal tracts. However, the activity and selectivity of these compounds toward gastrointestinal tracts are yet insufficient, and another defect of them is that they have an anticholinergic effect which causes side effects such as thirstiness and mydriasis. As social environments have been complicated recently, many of people feel the severe stress and patients with irritative bowel syndrome having cardinal symptoms of irregular bowel movement and abdominal pain are increasing in number. Medicines used for improving these diseases are, for example, cholinergic blocking agents, laxatives, antidiarrheal agents, intestinal drugs, mucosal paralyzers, gastrointestinal function regulators, autonomic nerve regulators, Chinese medicines, anxiolytic agents, antidepressant agents, sleep promoting drugs and neurotropic agents. However, the clinical effects of these medicines are yet insufficient and, in addition, they are not always satisfactory from the viewpoint of side effects of them. Under these circumstances, the development of medicines of a new type for improving the gastrointestinal function regulators, which have no side effect, is demanded.

Substituted pyridines useful as modulators of acetylcholine receptors Inventor(s): Cosford; Nicholas D. (San Diego, CA), Vernier; Jean-Michel (San Diego, CA) Assignee(s): Merck & Co., Inc. (Rahway, NJ) Patent Number: 6,194,581 Date filed: December 22, 1998 Abstract: In accordance with the present invention, there is provided a class of pyridine compounds which are modulators of acetylcholine receptors. The compounds of the invention displace acetylcholine receptor ligands from their binding sites. Invention compounds may act as agonists, partial agonists, antagonists or allosteric modulators of acetylcholine receptors, and are useful for a variety of therapeutic applications, such as the treatment of Alzheimer's disease and other disorders involving memory loss and/or dementia (including AIDS dementia); disorders of attention and focus (such as attention
148 Irritable Bowel Syndrome
deficit disorder); disorders of extrapyramidal motor function such as Parkinson's disease, Huntington's disease, Gilles de la Tourette syndrome and tardive dyskinesia; mood and emotional disorders such as depression, panic, anxiety and psychosis; substance abuse including withdrawal syndromes and substitution therapy; neuroendocrine disorders and dysregulation of food intake, including bulimia and anorexia; disorders of nociception and control of pain; autonomic disorders including dysfunction of gastrointestinal motility and function such as inflammatory bowel disease, irritable bowel syndrome, diarrhea, constipation, gastric acid secretion and ulcers; pheochromocytoma; cardiovascular dysfunction including hypertension and cardia arrhythmias, comedication in surgical procedures, and the like. Excerpt(s): The present invention relates to novel compounds which are capable of modulating acetylcholine receptors. Invention compounds are useful, for example, for treatment of dysfunction of the central or autonomic nervous systems including dementia, cognitive disorders, neurodegenerative disorders, extrapyramidal disorders, convulsive disorders, cardiovascular disorders, endocrine disorders, pain, gastrointestinal disorders, eating disorders, affective disorders, and drug abuse. In addition, the present invention relates to pharmaceutical compositions containing these compounds, as well as various uses therefor. By modulation of neurotransmitter release (including dopamine, norepinephrine, acetylcholine and serotonin) from different brain regions, acetylcholine receptors are involved in the modulation of neuroendocrine function, respiration, mood, motor control and function, focus and attention, concentration, memory and cognition, and the mechanisms of substance abuse. Ligands for acetylcholine receptors have been demonstrated to have effects on attention, cognition, appetite, substance abuse, memory, extrapyramidal function, cardiovascular function, pain and gastrointestinal motility and function. The distribution of acetylcholine receptors that bind nicotine, i.e., nicotinic acetylcholine receptors, is widespread in the brain, including the basal ganglia, limbic system, cerebral cortex and mid- and hind-brain nuclei. In the periphery, the distribution includes muscle, autonomic ganglia, the gastrointestinal tract and the cardiovascular system. Acetylcholine receptors have been shown to be decreased, inter alia, in the brains of patients suffering from Alzheimer's disease or Parkinson's disease, diseases associated with dementia, motor dysfunction and cognitive impairment. Such correlations between acetylcholine receptors and nervous system disorders suggest that compounds that modulate acetylcholine receptors will have beneficial therapeutic effects for many human nervous system disorders. Thus, there is a continuing need for compounds which can selectively modulate the activity of acetylcholine receptors. In response to such need, the present invention provides a new family of compounds which modulate acetylcholine receptors. Web site: http://www.delphion.com/details?pn=US06194581__ •

152 Irritable Bowel Syndrome
Excerpt(s): This application claims the benefit of priority to U.S. Provisional Patent Application serial No. 60/313,934, filed Aug. 21, 2001; and U.S. Provisional Patent Application serial No. 60/353,517, filed Jan. 31, 2002. Dopamine, norepinephrine and serotonin are mammalian monoamine neurotransmitters that play important roles in a wide variety of physiological processes. Therefore, compounds that selectively modulate the activity of these three neurotransmitters, either individually, in pairs, or as a group, promise to serve as agents effective in the treatment of a wide range of maladies, conditions and diseases that afflict mammals due to atypical activities of these neurotransmitters. For example, depression is believed to result from dysfunction in the noradrenergic, dopaminergic, or serotonergic systems. Furthermore, the noradrenergic system appears to be associated with increased drive, whereas the serotonergic system relates more to changes in mood. Therefore, it is possible that the different symptoms of depression may benefit from drugs acting mainly on one or the other of these neurotransmitter systems. On the other hand, a single compound that selectively affects both the noradrenergic and serotonergic systems should prove effective in the treatment of depression comprising symptoms related to dysfunction in both systems.

They are likely to be useful in the treatment of diseases or conditions modulated by opiate receptors, for example irritable bowel syndrome; constipation; nausea; vomiting; pruritic dermatoses, such as allergic dermatitis and atopy; eating disorders; opiate overdoses; depression; smoking and alcohol addiction; sexual dysfunction; shock; stroke; spinal damage; and head trauma. Excerpt(s): This claims application claims priority under 35 U.S.C. 120 of U.S. Ser. No. 09/883,567, filed Jun. 18, 2001. This invention relates to pharmaceutically useful compounds, in particular compounds that bind to opiate receptors (e.g. mu, kappa and delta opioid receptors). Compounds that bind to such receptors are likely to be useful in the treatment of diseases modulated by opiate receptors, for example irritable bowel syndrome; constipation; nausea; vomiting; and pruritic dermatoses, such as allergic dermatitis and atopy in animals and humans. Compounds that bind to opiate receptors have also been indicated in the treatment of eating disorders, opiate overdoses, depression, smoking and alcohol addiction, sexual dysfunction, shock, stroke, spinal damage and head trauma. There is a particular need for an improved treatment of itching. Itching, or pruritus, is a common dermatological symptom that can give rise to considerable distress in both humans and animals.

Excerpt(s): The present invention relates to aminoalkyl substituted 5,6,7,8-tetrahydro9H-pyridino[2,3-b]indole and 5,6,7,8-tetrahydro-9H-pyrimidino[4,5-b]indole derivatives, pharmaceutical compositions containing such compounds and their use in treating psychiatric disorders, neurological diseases, immunological, cardiovascular or heart-related diseases and colonic hypersensitivity associated with psychopathological disturbance and stress. Corticotropin releasing factor (herein referred to as CRF), a 41 amino acid peptide, is the primary physiological regulator of proopiomelanocortin (POMC) derived peptide secretion from the anterior pituitary gland [J. Rivier et al., Proc. Nat. Acad. Sci. (USA) 80:4851 (1983); W. Vale et al., Science 213:1394 (1981)]. In addition to its endocrine role at the pituitary gland, immunohistochemical localization of CRF has demonstrated that the hormone has a broad extrahypothalamic distribution in the central nervous system and produces a wide spectrum of autonomic, electrophysiological and behavioral effects consistent with a neurotransmitter or neuromodulator role in brain [W. Vale et al., Rec. Prog. Horm. Res. 39:245 (1983); G. F. Koob, Persp. Behav. Med. 2:39 (1985); E. B. De Souza et al., J. Neurosci. 5:3189 (1985)]. There is also evidence that CRF plays a significant role in integrating the response of the immune system to physiological, psychological, and immunological stressors [J. E. Blalock, Physiological Reviews 69:1 (1989); J. E. Morley, Life Sci. 41:527 (1987)]. Clinical data provide evidence that CRF has a role in psychiatric disorders and neurological diseases including depression, anxiety-related disorders and feeding disorders. A role for CRF has also been postulated in the etiology and pathophysiology of Alzheimer's disease, Parkinson's disease, Huntington's disease, progressive supranuclear palsy and

amyotrophic lateral sclerosis as they relate to the dysfunction of CRF neurons in the central nervous system [for review see E. B. De Souza, Hosp. Practice 23:59 (1988)]. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •
Bifidobacterium in the treatment of inflammatory disease Inventor(s): Collins, John Kevin; (Duncloyne, IE), O'Mahony, Liam; (Cork, IE), O'Sullivan, Gerald Christopher; (Cork, IE), Shanahan, Fergus; (Kinsale, IE) Correspondence: Jacobson Holman Pllc; 400 Seventh Street N.W.; Suite 600; Washington; DC; 20004; US Patent Application Number: 20030170217 Date filed: March 3, 2003 Abstract: A strain of Bifidobacterium isolated from resected and washed human gastrointestinal tract is significantly immunomodulatory following oral consumption in humans. The strain is useful in the prophylaxis and/or treatment of undesirable inflammatroy activity, especially gastrointestinal inflammatory activity such as inflammatory bowel disease or irritable bowel syndrome. The inflammatory activity may also be due to cancer. Excerpt(s): This invention relates to probiotic Bifidobacterium strains which have various applications in foodstuffs and in medicine. More particularly, the invention relates to probiotic strains of bifidobacteria which are capable of beneficially modifying and consequently alleviating observable symptoms in inflammatory disease. Consumers are becoming increasingly aware of matters which may be necessary for maintenance of their environment, health and nutrition. In response, scientific research has focussed upon the roles that diet, stress, and modern medical practices (e.g. antibiotics and radiotherapy) may play in threatening human health. In particular, population dynamics shifting towards older societies are increasing the incidence of illnesses which may be caused by deficient or compromised microflora such as gastrointestinal tract (GIT) infections, constipation, irritable bowel syndrome (IBS), inflammatory bowel disease (IBD)--Crohn's disease and ulcerative colitis, food allergies, antibiotic-induced diarrhoea, cardiovascular disease, and certain cancers (e.g. colorectal cancer). Probiotics have been defined as live microbial food supplements which beneficially affect the host by improving the intestinal microbial balance, or more broadly, as living microorganisms, which upon ingestion in certain numbers, exert health effects beyond inherent basic nutrition. Cocktails of various micro-organisms particularly species of Lactobacillus and Streptococcus, have traditionally been used in fermented dairy products to promote health.

The inventive coadministration is useful in the treatment of diseases affected by activity of cAMP-PDE, including without limitation, inflammatory bowel disease, irritable bowel syndrome, rheumatoid arthritis, osteoarthritis, pancreatis, psoriasis, migraine, Alzheimer's Disease, Parkinson's disease, transplant rejection, asthma, acute respiratory distress syndrome, chronic obstructive pulmonary disease, stroke, and neurodegeneration of, and consequences of traumatic brain injury. Excerpt(s): This application claims the benefit of priority of U.S. applications Serial Nos. 60/273,206, and 60/273,291, filed Mar. 2, 2001, and U.S. Serial No. 60/289,719 filed May 9, 2001, the entire contents of which are incorporated herein by reference. The present invention relates to methods for treating diseases associated with intracellular levels of cAMP comprising co-administration of at least one compound that is a melanocortin receptor agonist and at least one compound that is a cAMP-PDE inhibitor, and to pharmaceutical compositions for practicing the claimed methods. Cyclic adenoise 3',5' monophosphate (cyclic AMP or cAMP) is a nucleotide messenger associated with inflammatory cell activity; it mediates the functional responses of cells to a multitide of hormones and neurotransmitters, including NF-.kappa.B. NF-.kappa.B is a pivotal component of the pro-inflammatory cascade, and its activation is a central event in initiating many inflammatory diseases. In a typical inflammatory response, NF-.kappa.B is activated in response to an inflammatory stimulus and once activated, induces expression of a wide array of pro-inflammatory genes.

Early detection marker for chronic inflammatory associated diseases Inventor(s): Pereira, Heloise Anne; (Edmond, OK) Correspondence: Dunlap, Codding & Rogers P.C.; PO Box 16370; Oklahoma City; OK; 73114; US Patent Application Number: 20030170745 Date filed: March 7, 2003 Abstract: The present invention in one embodiment is an early detection marker for chronic inflammatory-associated diseases, including atherosclerosis, Alzheimer's disease, asthma, rheumatoid arthritis, osteoarthritis, and inflammatory diseases of the bowel such as Crohn's disease, Ulcerative colitis, Irritable bowel syndrome and Inflammatory bowel disease. The method, for example may comprise (1) obtaining a fluid sample from the subject, wherein the subject does not have an acute bacterial or viral infection when the fluid sample is obtained, (2) testing the fluid sample for a circulating or secreted CAP37 protein, and (3) concluding that the subject has a chronic inflammatory-associated disease when the CAP37 protein is detected in the fluid sample. The fluid sample may comprise serum, plasma, or cerebrospinal fluid, for example, or any other body fluid exposed to endothelial, vascular, or neuronal secretions. Excerpt(s): This application claims the benefit of U.S. Serial No. 60/363,114, filed Mar. 8, 2002, which is hereby expressly incorporated herein by reference in its entirety. The present invention relates to, but is not limited to, methods for detecting inflammatoryassociated diseases by detecting CAP37 proteins in a body fluid. Cationic Antimicrobial Protein of M.sub.r 37 kDa (CAP37) was originally isolated from granule extracts of human polymorphonuclear leukocytes (PMN) in 1984 (1). The amino acid sequence of PMN-CAP37 revealed its relation to members of the serine protease family that have a conserved catalytic active site consisting of his-57, asp-102 and ser-195 in the charge relay system (2). Of these sites, the conserved histidine and serine of the catalytic triad have been replaced with serine and glycine residues, respectively, rendering CAP37 ineffective as a serine protease (2,3). However, CAP37 has been demonstrated to have a diverse and exciting repertoire of functions. It was first analyzed regarding its bactericidal properties against Gram negative bacteria including, but not limited to, Salmonella typhimurium, Escherichia coli and Pseudomonas aeruginosa (4) and its ability to bind to and neutralize lipopolysaccharide (LPS)(5). Subsequently we showed CAP37 to be a potent chemoattractant for monocytes (6). Additionally, regarding its effects on the monocyte, CAP37 has been reported to stimulate their survival and thrombospondin secretion (7), also to enhance the LPS-stimulated release of prostaglandin E2 (8), interleukin 6 (IL-6)(9) and tumor necrosis factor-alpha (TNF.alpha.)(8-10). To add even further to its extensive range of known functions, CAP37 has been demonstrated to stimulate the reversible contraction of fibroblasts and endothelial cells (7) and to activate endothelial cell protein kinase C (PKC)(11). Recently, CAP37 released from stimulated PMN was reported to be taken up and sequestered in nearby endothelial mitochondria and has been suggested to protect against apoptosis (12).

Effects of glucagon-like peptide-1 (7-36) on antro-pyloro-duodenal motility Inventor(s): Goeke, Burkhard; (Gauting, DE), Schirra, Joerg; (Kirchhain, DE) Correspondence: Arnold & Porter; Attn: IP Docketing Department, Room 1126b; 555 Twelfth Street, NW; Washington; DC; 20004-1206; US Patent Application Number: 20030216292 Date filed: June 9, 2003 Abstract: The present invention provides an effective method for inhibiting antroduodenal motility in healthy subjects and patients suffering from various disorders, without the side effects associated with other pharmaceutical compositions. GLP-1 slows antro-duodenal motility and may be used for the treatment or prevention of gastrointestinal disorders such as diarrhea, postoperative dumping syndrome and irritable bowel syndrome, and also premedication in endoscopic procedures. Excerpt(s): The present invention relates to inhibiting antro-duodenal motility with GLP-1 and methods to alleviate discomfort during endoscopy and to alleviate symptoms of gastrointestinal disorders. Glucagon has been widely used to cause a variable reduction in gastroduodenal motility. The effect of glucagon appears to be dose-dependent with a minimally effective dose being 0.5 mg. Glucagon, however, does not facilitate colonoscopic evaluation (Norfleet, Gastrointest. Endosc., 24, 164-5, 1978), and at doses as high as 2 mg glucagon does not reduce contractions in the antrum (Gregerson et al., Scand. J. Gastroenterol. 23 (Supp 152), 42-47 (1988)). Furthermore, glucagon is contraindicated in persons with diabetes (Paul & Freyschmidt, ROFO Rortschr. Geb. Rontgenstr. Nuklearmed., 125, 31-7 (1996)), is expensive and its efficacy has been questioned. Side effects associated with the use of glucagon include nausea and vomiting. The effects are dose-dependent and can appear at a dose of 1 mg (Larsen et al., Scand. J. Gastroenterol. 21, 634-640, 1986; Gregersen et al., supra, Diamant Handbook Experimental Pharm, Lefevre ed., Vol. 66/2, 611-643, 1983). As dosages required to sufficiently reduce motility frequently exceed 1 mg, side effects from glucagon use are common. Such side effects render the patient extremely uncomfortable and often cause the endoscopic procedure to be interrupted or aborted. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

These priority applications are hereby incorporated herein in their entireties. This invention relates to compounds which are novel imidazo[1,2-a]pyrazines, and to the use of such compounds as CRF receptor antagonists in the treatment of various neurological disorders. Corticotropin releasing factor (herein referred to as CRF), a 41 amino acid peptide, is the primary physiological regulator of proopiomelanocortin (POMC)-derived peptide secretion from the anterior pituitary gland [J. Rivier et al., Proc. Nat. Acad. Sci. (USA) 80:4851 (1983); W. Vale et al., Science 213:1394 (1981)]. In addition to its endocrine role at the pituitary gland, immunohistochemical localization of CRF has demonstrated that the hormone has a broad extrahypothalamic distribution in the central nervous system and produces a wide spectrum of autonomic, electrophysiological and behavioral effects consistent with a neurotransmitter or neuromodulator role in brain [W. Vale et al., Rec. Prog. Horm.

There is also evidence that CRF plays a significant role in integrating the response of the immune system to physiological, psychological, and immunological stressors [J. E. Blalock, Physiological Reviews 69:1 (1989); J. E. Morley, Life Sci. 41:527 (1987)]. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

Excerpt(s): The present invention relates to pharmaceutical compositions and methods for the treatment of irritable bowel disease (IBD) [also termed: irritable bowel syndrome (IBS)]; more particularly for the treatment of diarrhea-predominant IBD. Irritable bowel syndrome (IBS), a chronic or recurring gastrointestinal disorder, afflicts as many as 24% of women and 19% of men in the U.S., Europe, Japan, and China. IBS produces abdominal pain or discomfort in its victims and accounts for about one-eighth of primary care and more than one-fourth of gastroenterology practice. IBS has tremendous societal and economic impact since persons with IBS symptoms miss three times as many work days as those without and incur 70% higher health care costs. The American Gastroenterological Association has recently underscored the importance of IBS by issuing both a position statement (American Gastroenterological Association (AGA) Medical Position Statement: Irritable Bowel Syndrome. Gastroenterology 112:2118-2119 (1997)) and a technical review (Drossman D A, Whitehead W E, Camilleri M., "Irritable bowel syndrome: a technical review for practice guideline development", Gastroenterology 112:2120-2137 (1997)) on IBS. The description herein of IBS is based chiefly on these documents and on other current literature (such as that reviewed in Snape W J Jr., "Irritable bowel syndrome", In: Bockus Gastroenterology, 5th edition (W. S. Haubrich, F. Schoffner, ed.) Philadelphia: W. B. Saunders, pp. 1619-1636 (1995)). IBS presents itself as abdominal pain accompanied by altered bowel habits. There is no established biological marker for IBS, which appears to result from faulty regulation in both the gastrointestinal and nervous systems. Once clinicians rule out other possible causes of IBS symptoms, they must devise a treatment plan based upon the severity and nature of the symptoms as well as other factors such as the degree of impairment the individual is experiencing in the activities of daily living. At present, treatment options
162 Irritable Bowel Syndrome
range from education and dietary modification to drug therapy to psychological therapy. Drug and/or psychological therapy is called for in those 30% of IBS patients with moderate or severe symptoms. Given an IBS prevalence of 19% to 24%, IBS sufferers requiring such therapy represent 6-7% of the population at large, or well over 100 million individuals in continual need of such therapy in the U.S., Europe, Japan, and China.

Methods for treating apnea, apnea disorders, and other disorders using optically pure (-) norcisapride Inventor(s): Barberich, Timothy J.; (Concord, MA), Rubin, Paul D.; (Sudbury, MA) Correspondence: Pennie & Edmonds Llp; 1667 K Street NW; Suite 1000; Washington; DC; 20006 Patent Application Number: 20030158229 Date filed: February 26, 2003 Abstract: Methods for the prevention, treatment, or management of apnea, apnea disorders, bulimia nervosa, irritable bowel syndrome, urinary incontinence, bradycardia, bradyarrhythmia, syncope, other disorders, or symptoms thereof using (-) norcisapride, or a pharmaceutically acceptable salt thereof, substantially free of its (+) stereoisomer. Excerpt(s): The invention relates to methods of prevention, treatment, or management, of apnea, apnea disorders, bulimia, other disorders, or symptoms thereof. Apnea is defined in Stedman's Medical Dictionary, 26.sup.th Edition, Williams and Wilkins (1995), as the absence of breathing. There are a number of disorders associated with apnea, which are characterized by interrupted breathing in which a person stops breathing long enough to decrease the amount of oxygen and increase the amount of carbon dioxide in the blood and brain Each type of apnea involves the absence of airflow at the nose or the mouth, typically for at least 10 seconds. Various apnea disorders exist, including: central apnea, which results from medullary depression and inhibits respiratory movement; deglutition apnea, which is the inhibition of breathing during swallowing; obstructive or peripheral apnea, which is either a result of obstruction of air passages or inadequate respiratory muscle activity; sleep apnea, which is central and/or obstructive apnea during sleep; and sleep induced apnea, which results from failure of the respiratory center to stimulate adequate respiration during sleep.

Adequate sexual function is a complex interaction of hormonal events and psychosocial relationships. There are four stages to sexual response as described in the International Journal of Gynecology & Obstetrics, 51(3):265-277 (1995). The first stage of sexual response is desire. The second stage of sexual response is arousal. Both physical and emotional stimulation may lead to breast and genital vasodilation and clitoral engorgement (vasocongestion). In the female, dilation and engorgement of the blood vessels in the labia and tissue surrounding the vagina produce the "orgasmic platform," an area at the distal third of the vagina where blood becomes sequestered. Localized perivaginal swelling and vaginal lubrication make up the changes in this stage of sexual response. Subsequently, ballooning of the proximal portion of the vagina and elevation of the uterus occurs. In the male, vasodilation of the cavernosal arteries and closure of the venous channels that drain the penis produce an erection. The third stage of sexual response is orgasm, while the fourth stage is resolution. Interruption or absence of any of the stages of the sexual response cycle can result in sexual dysfunction. One study found that 35% of males and 42% of females reported some form of sexual dysfunction. Read et al, J. Public Health Med., 19(4):387-391 (1997).

The subject invention also provides methods for synthesizing the compounds of invention. The invention also provides methods for the treatment of irritable bowel syndrome and other such conditions. Excerpt(s): This application claims the benefit of U.S. Provisional Application Serial No. 60/350,504, filed Jan. 18, 2002. Irritable bowel syndrome (IBS) is one of the most common gastrointestinal disorder thought to result from dysregulation of intestinal motor, sensory and CNS function. In the United States, the estimated prevalence is 15% to 20%, and 75% of patients are women. Despite its prevalence, IBS is poorly understood. It is one of over 20 functional gastrointestinal (GI) disorders that are not explained by identifiable structural or biochemical abnormalities. IBS is characterized by persistent or recurrent symptoms of abdominal pain with diarrhea and/or constipation. IBS is believed to relate to abnormalities in motility and/or afferent sensitivity as

mediated by the central nervous system. Patients with IBS have a diminished quality of life and use significant health care resources. Treatment for patients diagnosed with IBS has included antidepressant drugs, tranquilizers and laxatives. Pharmacological intervention in diarrhea-predominant IBS focuses on the reduction of bowel motility, spasms and transit times. Peripherally acting opiod ligands such as the petidine congeners diphenoxylate and loperamide and the k-opiod agonist fedotozine slow gastrointestinal transit by their effects on the circular and longitudinal muscle. While these drugs show some effects on intestinal motility, their effects on IBS-related abdominal pain and intestinal relief is generally insufficient.

Yet, the diseases described above are only for enumeration, not to limit the scope of clinical application of vanilloid receptor modulator. Capsaicin (8-methyl-N-vanillyl-6-nonenamide) is a main pungent component in hot peppers. Hot peppers have been used, for a long time, not only as a spice but also as traditional medicine in the treatment of gastric disorders and when applied locally, for the relief of pain and inflammation (Szallasi and Blumberg, 1999, Pharm, Rev. 51, ppl59-211). Capsaicin has a wide spectrum of biological actions, and not only exhibits effects on the cardiovascular and respiratory systems but also induces pain and irritancy on local application. Capsaicin, however, after such induction of pain, induces desensitization, both to capsaicin itself and also to other noxious stimuli to make the pain stopped. Based on this property, capsaicin and its analogues such as olvanil, nuvanil, DA-5018, SDZ-249482, resiniferatoxin are either used as analgesic agent, therapeutic agent for incontinentia urinae or skin disorder, or under development (riggleworth and Walpole, 1998, Drugs of the Future 23, pp 531-538).

N.W.; Washington; DC; 20004; US Patent Application Number: 20030113306 Date filed: July 25, 2002 Abstract: A Lactobacillus casei strain or a mutant or variant thereof isolated from resected and washed human gastrointestinal tract is significantly immunomodulatory following oral consumption in humans. In particular a Lactobacillus casei strain, AH101, AH104, AH111, AH112 or AH113 or mutants or variants are thereof are useful in the prophylaxis and/or treatment of inflammatory activity especially undesirable gastrointestinal inflammatory activity, such as inflammatory bowel disease or irritable bowel syndrome. Excerpt(s): The invention relates to Lactobacillus casei strains and their use as probiotic bacteria in particular as immunomodulatory biotherapeutic agents. The defense mechanisms to protect the human gastrointestinal tract from colonization by intestinal bacteria are highly complex and involve both immunological and non-immunological aspects (1). Innate defense mechanisms include the low pH of the stomach, bile salts, peristalsis, mucin layers and anti-microbial compounds such as lysozyme (2). Immunological mechanisms include specialized lymphoid aggregates, underlying M cells, called peyers patches which are distributed throughout the small intestine and colon (3). Luminal antigens presented at these sites result in stimulation of appropriate T and B cell subsets with establishment of cytokine networks and secretion of antibodies into the gastrointestinal tract (4). In addition, antigen presentation may occur via epithelial cells to intraepithelial lymphocytes and to the underlying lamina propria immune cells (5). Therefore, the host invests substantially in immunological defense of the gastrointestinal tract. However, as the gastrointestinal mucosa is the largest surface at which the host interacts with the external environment, specific control mechanisms must be in place to regulate immune responsiveness to the 100 tons of food which is handled by the gastrointestinal tract over an average lifetime. Furthermore, the gut is colonized by over 500 species of bacteria numbering 10.sup.11-10.sup.12/g in the colon. Thus, these control mechanisms must be capable of distinguishing non-pathogenic adherent bacteria from invasive pathogens, which would cause significant damage to the host. In fact, the intestinal flora contributes to defense of the host by competing with newly ingested potentially pathogenic micro-organisms. Bacteria present in the human gastrointestinal tract can promote inflammation. Aberrant immune responses to the indigenous microflora have been implicated in certain disease states, such as inflammatory bowel disease. Antigens associated with the normal flora usually lead to immunological tolerance and failure to achieve this tolerance is a major mechanism of mucosal inflammation (6). Evidence for this breakdown in tolerance includes an increase in antibody levels directed against the gut flora in patients with IBD. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Irritable Bowel Syndrome (IBS) is a bowel disease with variable symptoms, which may be referred to in Swedish as the equivalent of "irritable large intestine". There are no biological markers for the disease. Two systems of classification based on the symptoms have been drawn up to define the disease. One is known as the "Manning criteria" and the other as the "Rome criteria". In Manning, A. P., Thompson, W. G., Heaton, K. W., Morris, A. F.

J., 2:653-654, four symptoms are identified which, in a significant fashion, distinguish patients with IBS from patients with some other known organic disease; these are tension and swelling in the abdomen, pain alleviation in conjunction with bowel activity, more frequent bowel motions in conjunction with abdominal pains and looser bowel motions in conjunction with abdominal pains. In addition to these, it was also stated that two symptoms are also often encountered, namely mucous-like motions and a sense of incomplete evacuation of the bowel.

syndrome, diverticular disease, oesophageal achalasia, chronic obstructive airways disease, over active bladder including symptoms of incontinence, urge and frequency, urinary incontinence, neurogenic urinary urgency or pollakiuria, treatment of bladder functional disorder, urinary leakage, painful or difficult urination caused by neurogenic bladder, spastic or hypertonic bladder, dysfunctional bladder syndrome, gastrointestinal disorders including gastrointestinal hyperactivity, and relaxing effect on intestinal smooth muscle cells. European patent 0388054 describes a family of 3substituted pyrrolidine derivatives including darifenacin and pharmaceutically acceptable salts thereof as muscarinic receptor antagonists. The pharmaceutically acceptable salts include acid addition salts, specifically the hydrochloride, hydrobromide, hydrofluoride, sulphate or bisulphate, phosphate or hydrogen phosphate, acetate, besylate, citrate, fumarate, gluconate, lactate, maleate, mesylate, succinate and tartrate salts. The hydrobromide salt of darifenacin has been the preferred compound for medical usage. The salt is produced from the corresponding anhydrous free base. However, a problem associated with the free base is that it is very unstable, having a shelf life of only one month. Additionally it can be difficult to produce the free base in a sufficiently pure form for pharmaceutical use. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

Excerpt(s): This is a non-provisional application which claims the benefit of U.S. Provisional Application No. 60/336,865 filed Nov. 2, 2001. The present invention is directed to novel 2phenyl-5thiophenyl-2,4-- dihydro-[1,2,4]-triazol-3-one derivatives which are smooth muscle relaxants and therefore are useful in treating disorders responsive to relaxation of smooth muscle such as asthma, irritable bowel syndrome, male erectile dysfunction and particularly urinary incontinence. The present invention is also directed to a method of treatment with the novel compounds and to pharmaceutical compositions containing them. Urinary incontinence is a common condition that is the frequent cause of confinement to nursing homes among the elderly. It afflicts significant numbers among both men and women and all ages. In addition studies show some degree of daily incontinence reported among as many as 17% of young apparently healthy women. Safe and reliable methods for treating incontinence are clearly needed. Urinary incontinence is a manifestation of the failure to control the muscles of the bladder or urinary sphincter. Incontinence results when the pressure within the bladder is too great as a result of excessive force exerted by the bladder muscles, or when the sphincter muscles are too weak. Urinary incontinence can be a manifestation of other diseases such as Parkinsonism, multiple sclerosis, lesions of the central nervous system, or bladder infections. Interstitial cysts can result in instability of the bladder detusor muscles and a particularly unpleasant form of urge incontinence. Urinary incontinence is believed to currently affect over 12 million people in the United States alone, and to occur in between 15 and 30% of the population over 60. The current standard of care is quite unsatisfactory. All of the current drugs now utilized to treat urinary incontinence suffer from polypharmacology and unwanted side effects.

verapamil. Irritable Bowel Syndrome (IBS) results in about 3.5 million physician visits per year, and is the most common diagnosis made by gastroenterologists, accounting for about 25% of all patients diagnosed (Camilleri and Choi, Aliment Pharmacol. Ther., 11(1):3-15, 1997). Individuals afflicted with IBS visit doctors more frequently, enjoy a lower quality of life, and miss work more often relative to those with no bowel symptoms (Drossman et al., Dig. Dis. Sci., 38:1569-1580, 1993). As a consequence, individuals suffering from IBS incur significantly higher health care costs than those without the condition (Talley et al., Gastroenterology, 109:1736-1741, 1995).

Excerpt(s): Pursuant to 35 U.S.C.sctn. 119 (e), this application claims priority to the filing date of the U.S. Provisional Patent Application Serial No. 60/338,093 filed Nov. 8, 2001, the disclosure of which is herein incorporated by reference. The field of this invention is visceral pain, i.e., Irritable Bowel Syndrome, and the treatment thereof. Visceral pain affects the viscera, such as the intestines. One common type of visceral pain is Irritable Bowel Syndrome (IBS). IBS is a functional bowel disorder in which abdominal pain is associated with defecation or a change in bowel habits. IBS has elements of an intestinal motility disorder, a visceral sensation disorder, and a central nervous disorder. While the symptoms of IBS have a physiological basis, no clear mechanism unique to IBS has been identified. Rather, the same mechanisms that cause occasional abdominal discomfort in healthy individuals seem to operate to produce the symptoms of IBS. The symptoms of IBS are therefore a product of quantitative differences in the motor reactivity of the intestinal tract, and increased sensitivity to stimuli or spontaneous contractions.

Use of Lactobacillus salivarius Inventor(s): Collins, John Kevin; (Doughcloyne, IE), O'Mahony, Liam; (Cork, IE), O'Sullivan, Gerald Christopher; (Cork, IE), Shanahan, Fergus; (Kinsale, IE) Correspondence: Jacobson Holman Pllc; 400 Seventh Street N.W.; Suite 600; Washington; DC; 20004; US Patent Application Number: 20030166257 Date filed: September 12, 2002 Abstract: Lactobacillus salivarius is useful in the prophylaxis or treatment of undesirable inflammatory activity, especially gastrointestinal inflammatory activity such as inflammatory bowel disease or irritable bowel syndrome. The inflammatory activity may also be due to cancer. The Lactobacillus salivarius is of human origin isolated from resected and washed human gastrointestinal tract. One such strain is UCC 118 described in WO-A-9835014. Excerpt(s): The invention relates to the use of strains of Lactobacillus salivarius. The defence mechanisms to protect the human gastrointestinal tract from colonisation by intestinal bacteria are highly complex and involve both immunological and nonimmunological aspects (V. J. McCracken and H. R. Gaskins, `Probiotics a critical review`, Horizon Scientific Press, UK, 1999, p. 278.). Innate defence mechanisms include the low pH of the stomach, bile salts, peristalsis, mucin layers and anti-microbial compounds such as lysozyme (D. C. Savage, `Microbial Ecology of the Gut`, Academic Press, London, 1997, p.278.). Immunological mechanisms include specialised lymphoid aggregates, underlying M cells, called peyers patches which are distributed throughout the small intestine and colon (M. F. Kagnoff. Gastroenterol. 1993, 105, 1275). Luminal antigens presented at these sites result in stimulation of appropriate T and B cell subsets with establishment of cytokine networks and secretion of antibodies into the gastrointestinal tract (M. R. Neutra and J-P Kraehenbuhl, `Essentials of mucosal immunology`, Academic Press, San Diego, 1996, p.29., M. E. Lamm. Ann. Rev. Microbiol. 1997, 51, 311). In addition, antigen presentation may occur via epithelial cells to intraepithelial lymphocytes and to the underlying lamina propria immune cells (S. Raychaudhuri et al. Nat Biotechnol., 1998, 16, 1025). Therefore, the host invests substantially in immunological defence of the gastrointestinal tract. However, as the gastrointestinal mucosa is the largest surface at which the host interacts with the external environment, specific control mechanisms must be in place to regulate immune responsiveness to the 100 tons of food which is handled by the gastrointestinal tract over an average lifetime (F. Shanahan, `Physiology of the gastrointestinal tract`, Raven Press, 1994, p.643.). Furthermore, the gut is colonised by over 500 species of bacteria numbering 10.sup.11-10.sup.12/g in the colon. Thus, these control mechanisms must be capable of distinguishing non-pathogenic adherent bacteria from invasive pathogens which would cause significant damage to the host In fact, the intestinal flora contributes to defence of the host by competing with newly ingested potentially pathogenic microorganisms. Consumption of non-pathogenic, or probiotic, bacteria has resulted in enhancement of immune parameters in healthy volunteers. Examples of these immune modulatory effects are given in Table 1.

Use of rofleponide in the treatment of irritable bowel syndrome (ibs) Inventor(s): Brattsand, Ralph; (Lund, SE) Correspondence: White & Case Llp; Patent Department; 1155 Avenue OF The Americas; New York; NY; 10036; US Patent Application Number: 20030004214 Date filed: July 19, 2002 Abstract: The invention provides the use of rofleponide, its esters and salts in the manufacture of a medicament for use in the treatment of irritable bowel syndrome (IBS) and pharmaceutical formulations for use in such treatment. Excerpt(s): The present invention provides a new treatment for irritable bowel syndrome (IBS), namely use of rofleponide, its esters and salts. The irritable bowel syndrome is a chronic abdominal disease for which there is no apparent underlying structural cause. Symptoms in IBS are thought to arise from altered gastro-intestinal motility, increased visceral sensitivity or altered brain-gut modulation. The diagnosis of IBS is hampered by the absence of simple diagnostic tests. Physicians approach IBS as a diagnosis of exclusion and then base the diagnosis on certain diagnostic criteria such as abnormal discomfort and pain, bloating and disturbed defecation, see further in Gut, 1999; 45 (Suppl.2):II43, C1(Sept), Thompson et al., and Gasteroenterology 1997, vol. 112, p.2120-2137. Current treatment of IBS is mainly antispasmodics, laxatives, loperamide and antidepressants. A history of gastro-enteritis (Salmonella, Campylobacter etc.) is more commonly found in patients with IBS than in a control population and up to 30% of patients develop IBS after gastro-enteritis. According to the invention there is provided the use of rofleponide, its esters and salts, such as fatty acid esters e.g.

Irritable Bowel Syndrome (IBS) and Gastrointestinal Solutions Handbook Source: Encinitas, CA: United Research Publishers. 1997. 232 p. Contact: Available from United Research Publishers. Department RB-91, 103 North Coast Highway 101, Encinitas, CA 92024. PRICE: $14.95. ISBN: 096149249X. Summary: This book discusses irritable bowel syndrome (IBS) and other gastrointestinal problems and explains how readers can educate themselves, treat problems, and prevent recurrences of these conditions. The author discusses natural, alternative, and medical remedies that can bring relief without the use of drugs. The author also explains how the gastrointestinal system works, why certain foods, activities, and stress cause problems, and why over 20 million Americans deal with IBS and gastrointestinal distress. One chapter in the book discusses other diseases of the digestive tract and notes that they require a doctor's attention but are often easier to treat than IBS. IBS, however, can be individualistic, intermittent, and difficult to treat. The last section reviews some nontraditional helps and ideas that might be of use, including homeopathy, relaxation, hypnotherapy, aromatherapy, herbal remedies, and acupuncture. A final chapter lists fat grams and calories for many common foods.

[email protected]. Website: www.wiley.com. PRICE: $13.95 plus shipping and handling. ISBN: 0471347418. Summary: This book offers a multidisciplinary approach to managing irritable bowel syndrome (IBS). The authors note that because the complex nature of IBS may raise medical, nutrition, and psychological issues, a gastroenterologist, registered dietitian, and psychologist collaborated to write the book. The book is designed as a workbook for people with IBS to learn symptom management skills. The authors stress that successful management of IBS symptoms requires matching management strategies to the links between diet, stress, and symptoms that are specific to each individual. The first two chapters focus on diagnosing IBS. Additional chapters cover the causes of IBS, the importance of a healthy diet, dietary aggravators, diet adjustments for specific symptoms, stress management, coping with pain, managing IBS when other disease processes are present, and working with one's health care providers. The book includes self assessments, recordkeeping forms, and six different diet plans (to be used alone or in combination). The book includes a list of ten tips for living with an irritable bowel, and appendices that cover the physiology of the gut, Canada's food guide, high fiber and low fat recipes, and resources. The book concludes with a subject index.

Tell Me What to Eat If I Have Irritable Bowel Syndrome: Nutrition You Can Live With Source: Franklin Lakes, NJ: Career Press, Inc. 2000. 137 p. Contact: Available from Career Press, Inc. 3 Tice Road, P.O. Box 687, Franklin Lakes, NJ 07417. (800) 227-3371. Website: www.careerpress.com or www.newpagebooks.com. PRICE: $10.99 plus shipping and handling. Summary: This book offers eating and nutrition guidelines for people who have been diagnosed with irritable bowel syndrome (IBS). People with IBS have bowels that tend to overreact in certain situations. Whatever affects the bowels of the population at large, such as diet, hormones, or stress, affects those of people with IBS even more, resulting in the symptoms of the disorder. This book suggests an approach to managing IBS that includes eating a healthful diet (rich in high fiber foods that the patient can tolerate), drinking plenty of water, avoiding foods that make symptoms worse, and finding ways to minimize and handle the stress of daily living. The author cautions that treating IBS is like trying to hit a moving target; not only do IBS symptoms vary from one person to the next, they can also change from week to week in the same person. Similarly, different treatments work for different people and some treatments used for one symptom can cause a completely new symptom to occur. This book emphasizes the possible dietary treatments for IBS. The author notes that people with IBS who do not seem to respond well to drugs or dietary modification may want to concentrate on the psychological treatments available for IBS. The book offers seven chapters that cover common questions about IBS ('everything you ever wanted to ask a gastroenterologist'), the main symptoms of IBS, working with a dietitian to manage IBS, ten food steps to freedom, 20 recommended recipes, food shopping guidelines, and eating out at restaurants. The ten food steps include keep an FFS (food, feelings, symptoms) diary, eat high fiber foods, drink eight or more 8 ounce glasses of water, limit caffeine, avoid high fat meals and snacks, avoid trouble spice, avoid overdoing alcohol, avoid gassy foods, eat smaller more frequent meals, and exercise. A brief subject index concludes the book.

In addition to LOCATORPlus, in collaboration with authors and publishers, the National Center for Biotechnology Information (NCBI) is currently adapting biomedical books for the Web. The books may be accessed in two ways: (1) by searching directly using any search term or phrase (in the same way as the bibliographic database PubMed), or (2) by following the links to PubMed abstracts. Each PubMed abstract has a "Books" button that displays a facsimile of the abstract in which some phrases are hypertext links. These phrases are also found in the books available at NCBI. Click on hyperlinked results in the list of books in which the phrase is found. Currently, the majority of the links are between the books and PubMed. In the future, more links will be created between the books and other types of information, such as gene and protein sequences and macromolecular structures.

Summary: In this chapter, from a medical text on difficult decisions in digestive diseases, the authors explain irritable bowel syndrome (IBS), focusing on the role of reassurance in the management of IBS. They stress that, for the physician to effectively reassure the patient, both need security that the diagnosis is correct, and the decision to reassure can be a difficult one if the physician is not confident. Topics include differentiating IBS from other gastrointestinal diseases; diagnostic tests used to confirm the IBS diagnosis; the durability of the IBS diagnosis over time; the effectiveness of reassurance as a therapeutic tactic; and the six sequential steps in reassurance therapy. The authors conclude that the benign course of IBS makes reassurance an important initial management approach, but the treatment may have more than time-buying utility in many patients. 3 figures. 4 tables. 23 references.

Summary: This chapter is from a book that evaluates drug therapies for each of the four major functional disorders: chronic fatigue syndrome, fibromyalgia, irritable bowel syndrome (IBS), and premenstrual syndrome. In this chapter, the final of six short chapters that focus on IBS, the author reviews evidence based therapy for IBS. The author contradicts present thinking that drug therapy for IBS should focus on the most disturbing symptoms, using loperamide for diarrhea, fiber for constipation, and anticholinergic agents for pain. The author, instead, contends that research studies do not provide support for the effectiveness of these drug approaches. Because evidence indicates that tricyclic antidepressants are effective for the totality of this illness, the author contends that these drugs should constitute the first line treatment in all cases in which the severity of the syndrome warrants intervention, provided that there are no contraindications to the use of these agents and that the potential for drug interactions has been considered. Monotherapy with amitriptyline or desipramine should be initiated with a starting dose of 10 mg administered once a day in patients with the diarrhea predominant variant of the syndrome. Adjunctive therapy with a bulking agent may lead to a decrease in the overall severity of the syndrome in all patients and ease the bowel habit and stool passage in those with the constipation predominant variant of the syndrome.

PRICE: $10.99 plus shipping and handling. Summary: This chapter is from a book that offers eating and nutrition guidelines for people who have been diagnosed with irritable bowel syndrome (IBS). People with IBS have bowels that tend to overreact in certain situations. Whatever affects the bowels of the population at large, such as diet, hormones, or stress, affects those of people with IBS even more, resulting in the symptoms of the disorder. This chapter describes the main symptoms of IBS, which include abdominal pain, irregular pattern of defecation at least 25 percent of the time, constipation, diarrhea, mucus in the stool, abdominal bloating or swelling, the feeling of incomplete emptying rectum, and gas attacks (flatulence). The
194 Irritable Bowel Syndrome
author notes that, for many women, IBS symptoms seem to worsen during their periods (menstruation). Therefore, right before and during one's period, it is especially important to avoid trigger foods or stressors that seem to bring on or aggravate bowel symptoms. The chapter concludes with a brief discussion of common IBS symptoms that occur in other parts of the body. These can include heartburn, sleep disturbances, fatigue, bladder or urinary problems, non cardiac chest pain, nausea or bloating, pain in the upper abdomen, migraine headaches, painful intercourse, and fibromyalgia. •

Summary: This chapter on the coexistence of irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD) is from the second edition of a book devoted to the details of medical, surgical, and supportive management of patients with Crohn's disease (CD) and ulcerative colitis (UC), together known as IBD. Irritable bowel syndrome (IBS) is a chronic abdominal symptom complex for which no structural underlying abnormality can be demonstrated. It is a common disorder that affects all age groups with an increased frequency in females. Few if any of the clinical features of IBS can confidently distinguish it from IBD. The multiplicity and chronicity of symptoms and their relationship to altered bowel habit can be helpful hints. A psychoneurotic disposition, evidence of anxiety or depression, and a tendency to somatize symptoms referable not only to the gut but other organ systems are pointers in favor of IBS. However, when IBS occurs in a patient with established IBD, this can be a difficult diagnosis. Since IBS is a very common disorder, it is not unexpected to find patients with both IBS and IBD. The author considers whether there is a special relationship between these two disorders. There is good scientific evidence that inflammation of the gut alters its physiologic performance, and this may persist after resolution of the inflammation. The author concludes that IBS occurs with greater frequency in certain patients in remission from IBD, and this is more easily seen in UC than in CD. Symptoms of IBS in the context of IBD are no different from those typical for that condition. An awareness of this relationship is of key importance in making a confident diagnosis, as is a good knowledge of the patients' history and the characteristic behavior of their IBD. In some complicated IBD patients, extensive investigation by colonoscopy with or without small bowel radiography may be required. For most patients, treatment of IBS should follow the usual guidelines with notable exceptions in the case of patients with histories of obstruction. 1 figure. 17 references.

Summary: This chapter on the diagnosis and treatment of irritable bowel syndrome (IBS) is from a book that emphasizes the approaches of evidence based medicine in gastroenterology (the study of the gastrointestinal tract and gastrointestinal diseases) and hepatology (the study of the liver and liver diseases). Irritable bowel syndrome, the most common functional bowel disorder, is characterized by abdominal pain, bloating, and disturbed defecation. The functional gastrointestinal (GI) disorders result in significant utilization of health care resources; IBS is responsible for a considerable economic burden because of the high frequency of physician visits and work absenteeism. After consideration of demographic features, the nature of the symptoms, and the severity index, only limited investigations to rule out organic disease are indicated. The variety of symptoms, the lack of understanding of the pathophysiology of the disease, and the complex interaction of the central nervous system and the enteral nervous system and their receptors, suggest that no single drug will cure IBS. The authors recommend a strong physician-patient relationship to help control health care utilization. The goal should be judicious use of medical testing, within an atmosphere of an empathetic patient-doctor relationship. Recurrences should be treated by a symptom based approach, with careful attention to the psychosocial triggers that contribute to exacerbation. With a few simple investigations (tests), sympathetic explanation (patient education), and appropriate treatment, most patients with IBS have a good prognosis. 4 tables. 124 references. •

Summary: This chapter, from a medical textbook about the office management of common gastrointestinal diseases, discusses the management of the irritable bowel syndrome (IBS). Topics include pathogenesis, psychosocial factors, diagnosis, treatment issues, patient education, and specific therapy, including fiber supplements, anticholinergics, tranquilizers, opioids, antidepressants, and psychotherapy. The author stresses that successful treatment requires time, energy, and empathy; the interaction of the physician and the patient constitutes the treatment. 20 references.

Irritable bowel syndrome (IBS) is a chronic abdominal symptom complex for which no structural underlying abnormality can be demonstrated. It is a common disorder that affects all age groups with an increased frequency in females. Few if any of the clinical features of IBS can confidently distinguish it from IBD. This chapter focuses on the prevalence of
196 Irritable Bowel Syndrome
IBS, clinically relevant pathophysiology, and the importance of the patient-physician relationship. The author notes that there are several pathophysiologic alterations found in the small bowel and colon of patients with IBS that could be aggravated or brought to the level of clinical awareness by IBD or its treatment. These alterations include pain or diarrhea after ileo-right colon resection (removal); active proctosigmoiditis; ileal pouch procedures; and an exaggeration of the patient's response to secretagogues, including caffeine and problems with lactose intolerance. The author emphasizes the benefits of explaining to the patient with both IBS and IBD the fact that she or he has two different disorders and that each may cause its own symptoms. Explaining the pathophysiology seems to help the patient adjust medications and understand and accept symptoms caused by meals or by stress. 6 references.

Summary: The irritable bowel syndrome (IBS) is a familiar medical disorder characterized by symptoms of abdominal pain and disturbed defecation (diarrhea or constipation). However, management of patients with IBS has been complicated by a lack of precise definition of the syndrome, incomplete and conflicting views of its pathophysiology, and an absence of specific treatments. This continuing education program helps general or family physicians and gastroenterologists to understand the physiological basis for symptom generation in IBS; to improve diagnostic precision through the use of symptom-based criteria, as well as knowledge of the primary symptom type and the severity of the condition; to understand the illness experience and the patient's clinical outcome; and to plan an approach to treatment that incorporates management of both the biological and psychosocial contributions to this disorder. The videotape program and study guide are divided into two sections. The first section reviews the current pathophysiologic understanding of IBS and presents a biopsychosocial approach to diagnosis and treatment. The second section addresses the process of interaction with the patient, and the development of an effective physicianpatient relationship. 103 references. (AA-M).

New Testing Techniques for Irritable Bowel Syndrome Source: Newsletter for People with Lactose Intolerance and Milk Allergy. p. 3-4. Spring 1993. Contact: Available from Newsletter for People with Lactose Intolerance and Milk Allergy. P.O. Box 3129, Ann Arbor, MI 48106-3129.\ (313) 572-9134. Summary: This brief article, from a newsletter for people with lactose intolerance and milk allergy, reports on new testing techniques available for irritable bowel syndrome (IBS). Topics include the various etiologic agents possibly responsible for IBS; the traditional diagnostic methods used to confirm IBS; and the new test, called a bowel scintiscan, that reveals gaps in the emptying process of the large intestine. These gaps indicate areas of the bowel that function abnormally, therefore demonstrating the presence of IBS. The article notes that the test is still experimental and is only available through the Mayo Clinic in Rochester, Minnesota.

208 Irritable Bowel Syndrome
Summary: This article discusses irritable bowel syndrome (IBS), a very common condition that is characterized by abdominal pain associated with a change in a bowel pattern (constipation or diarrhea). IBS is considered a condition of the brain-gut connection and triggering factors may variously cause symptoms of diarrhea at one time and constipation at another. There is a wide range of severity of IBS, from mild or infrequent symptoms that the patient manages at home to very severe kinds of symptoms that can cause patients to seek relief with more frequent doctor visits. The article answers common questions about IBS and its treatments. IBS is in the group of conditions that are called functional gastrointestinal disorders, i.e., disorders of dysfunction, rather than pathology such as inflammation or visible tissue damage. Diagnosis include patient history, symptoms according to the Rome Criteria, and diagnostic tests such as colonoscopy or CT scan (computed tomography). Treatments are usually done in response to the specific symptoms. For example, in a patient who usually has constipation, treatment are used that increase the functioning of the bowel, the frequency, and the ease of having a bowel movement. For patients whose symptoms tend more to diarrhea, treatment includes anti diarrheal agents. Pain medications might also be indicated, particularly if the pain is meal related. Reduced dosage prescriptions of antidepressants can be effective to modulate or decrease pain. The author reviews new drugs currently under study, as well as ongoing research into the brain-gut connection. The author also discusses the impact of conceptualizing functional disorders within the traditional disease-based medical framework, which separates the mind from the body. IBS must be recognized as genuine, non trivial, and a disorder that is not fully explained as either psychiatric or organic. •

[email protected]. Summary: This article on irritable bowel syndrome (IBS) is from a newsletter for people with fibromyalgia (a pain disorder). IBS is known as a functional gastrointestinal (GI) disorder because it involves a healthy bowel, without inflammation or disease, that does not perform normally. In IBS, the bowel tends to have an unusual sensitivity to such events as the passage of food particles, fluids, or gas. IBS symptoms, which are usually intermittent rather than constant, are abdominal discomfort, cramping or pain, bloating, abnormal bowel movements (i.e., diarrhea, constipation, or the two alternating), mucus in the stools, and a sensation of incomplete evacuation. IBS is quite common among persons with fibromyalgia; its incidence is estimated at approximately 40 percent among patients with diagnosed fibromyalgia (compared with only 16 percent in normal controls). However, some GI signs are not part of IBS and should be investigated. The author then discusses the pathophysiology of IBS and the treatment options for the syndrome. Although admittedly not high tech, modifying the diet and eating habits and learning to control stress are the most potent weapons available against IBS. Dietary fiber has a central role, and it is important to increase one's intake of fiber slowly to allow the body to adjust and to drink plenty of water as fiber intake increases. The article concludes with the contact information for the International Foundation for Functional Gastrointestinal Disorders and for the National Institute of Diabetes and Digestive and Kidney Diseases of the National Institutes of Health. 18 references.

Contact: Available from Mayo Foundation for Medical Education and Research. 200 First Street, SW, Rochester, MN 55905. Summary: This newsletter article offers strategies to help people with irritable bowel syndrome (IBS) gain control of their symptoms. IBS is a common, chronic gastrointestinal disorder in which the structure of the bowel is normal, but the function is not. The symptoms are produced, in part, by spasms in the walls of the intestines. Some people mainly experience cramping and diarrhea, others alternate between constipation and diarrhea, or have predominantly pain and constipation. Bloating and gas are also common. IBS can be difficult to diagnose because many conditions have similar symptoms. Common treatments include dietary changes, managing stress, the use of medications, antidepressants, and alternative therapies, such as peppermint oil. A sidebar addresses the issue of a psychological basis for IBS, concluding that stress no doubt aggravates IBS, but that one doesn't have to be under stress to have the condition. 1 figure.

[email protected]. Website: www.iffgd.org. Summary: This newsletter article reviews the current approach to the diagnosis of irritable bowel syndrome (IBS). Physicians now rely less on extensive testing to exclude other disorders and instead can diagnose IBS in most patients by recognizing certain symptom details, performing a physical examination, and undertaking limited diagnostic testing. Extensive testing is usually reserved for special situations. Various symptom criteria have been proposed; the Rome II criteria are presently in use. Rome II criteria for IBS are symptoms at least 12 weeks or more in duration, which need not be consecutive, in the preceding 12 months of abdominal discomfort or pain that has two out of three features: relieved with defecation, onset associated with a change in frequency of stool, or onset associated with a change in form (appearance) of stool. Other symptoms that are not essential but that support the diagnosis of IBS include abnormal stool frequency (greater than 3 bowel movements per day or less than 3 bowel movements per week), abnormal stool form, abnormal stool passage, passage of mucus, or bloating or feeling of abdominal distension. The discomfort or pain and abnormal bowel habit of IBS typically fluctuate in severity, may be associated with stressful life events, and occur over a long time period. Diagnostic tests can include blood tests, stool tests, sigmoidoscopy or colonoscopy, barium enema, and psychological tests. Diagnosis by careful review of the patient's symptoms, a physical examination, and selected diagnostic procedures is quite secure, as followup for many years of confidently diagnosed patients seldom disclose another cause for their symptoms. With an unequivocal diagnosis, both patient and physician can work together on the most effective management.

CHAPTER 10. RESEARCHING MEDICATIONS Overview While a number of hard copy or CD-ROM resources are available for researching medications, a more flexible method is to use Internet-based databases. Broadly speaking, there are two sources of information on approved medications: public sources and private sources. We will emphasize free-to-use public sources.
U.S. Pharmacopeia Because of historical investments by various organizations and the emergence of the Internet, it has become rather simple to learn about the medications recommended for irritable bowel syndrome. One such source is the United States Pharmacopeia. In 1820, eleven physicians met in Washington, D.C. to establish the first compendium of standard drugs for the United States. They called this compendium the U.S. Pharmacopeia (USP). Today, the USP is a non-profit organization consisting of 800 volunteer scientists, eleven elected officials, and 400 representatives of state associations and colleges of medicine and pharmacy. The USP is located in Rockville, Maryland, and its home page is located at http://www.usp.org/. The USP currently provides standards for over 3,700 medications. The resulting USP DI® Advice for the Patient® can be accessed through the National Library of Medicine of the National Institutes of Health. The database is partially derived from lists of federally approved medications in the Food and Drug Administration’s (FDA) Drug Approvals database, located at http://www.fda.gov/cder/da/da.htm. While the FDA database is rather large and difficult to navigate, the Phamacopeia is both user-friendly and free to use. It covers more than 9,000 prescription and over-the-counter medications. To access this database, simply type the following hyperlink into your Web browser: http://www.nlm.nih.gov/medlineplus/druginformation.html. To view examples of a given medication (brand names, category, description, preparation, proper use, precautions, side effects, etc.), simply follow the hyperlinks indicated within the United States Pharmacopeia (USP). Below, we have compiled a list of medications associated with irritable bowel syndrome. If you would like more information on a particular medication, the provided hyperlinks will direct you to ample documentation (e.g. typical dosage, side effects, drug-interaction risks,

Commercial Databases In addition to the medications listed in the USP above, a number of commercial sites are available by subscription to physicians and their institutions. Or, you may be able to access these sources from your local medical library.
Mosby’s Drug Consult™ Mosby’s Drug Consult™ database (also available on CD-ROM and book format) covers 45,000 drug products including generics and international brands. It provides prescribing information, drug interactions, and patient information. Subscription information is available at the following hyperlink: http://www.mosbysdrugconsult.com/.
PDRhealth The PDRhealth database is a free-to-use, drug information search engine that has been written for the public in layman’s terms. It contains FDA-approved drug information adapted from the Physicians’ Desk Reference (PDR) database. PDRhealth can be searched by brand name, generic name, or indication. It features multiple drug interactions reports. Search PDRhealth at http://www.pdrhealth.com/drug_info/index.html.

Summary: This report offers a continuing education activity for physicians who see patients with irritable bowel syndrome (IBS). The authors outline the characteristics and presenting symptoms of various patient subtypes and report on recent findings indicating the central role of serotonin in the pathophysiology of IBS, as well as new pharmacotherapeutic agents (drug therapy) developed for IBS. Approximately 95 percent of all serotonin (5HT) is located in the gastrointestinal (GI) tract; the remainder is located in the central nervous system. The abundance of 5HT in the GI tract indicates that this neurotransmitter plays a major role in GI function. 5HT modulates motility (movement through the GI tract), visceral perception (feelings, such as pain, arising from the gut), and intraluminal secretion; these are all roles that have been linked to the pathophysiology of IBS. Until recently, no pharmaceutical agents have been developed specifically for IBS. The ability of 5HT2 and 5HT4 agents to reduce the multiple symptoms associated with IBS provides not only direct relief but indirect relief as well, and confirms the neurobiologic basis of this GI disorder of function. Specific drugs discussed include alosetron (a 5HT2 antagonist), tegaserod (a 5HT4 agonist), and prucalopride (a 5HT4 agaonist). A posttest is appended, with which readers can qualify for continuing education credits. References are provided in the text of the report. 4 figures. 1 table.

APPENDIX B. PATIENT RESOURCES Overview Official agencies, as well as federally funded institutions supported by national grants, frequently publish a variety of guidelines written with the patient in mind. These are typically called “Fact Sheets” or “Guidelines.” They can take the form of a brochure, information kit, pamphlet, or flyer. Often they are only a few pages in length. Since new guidelines on irritable bowel syndrome can appear at any moment and be published by a number of sources, the best approach to finding guidelines is to systematically scan the Internet-based services that post them.
Patient Guideline Sources The remainder of this chapter directs you to sources which either publish or can help you find additional guidelines on topics related to irritable bowel syndrome. Due to space limitations, these sources are listed in a concise manner. Do not hesitate to consult the following sources by either using the Internet hyperlink provided, or, in cases where the contact information is provided, contacting the publisher or author directly. The National Institutes of Health The NIH gateway to patients is located at http://health.nih.gov/. From this site, you can search across various sources and institutes, a number of which are summarized below. Topic Pages: MEDLINEplus The National Library of Medicine has created a vast and patient-oriented healthcare information portal called MEDLINEplus. Within this Internet-based system are “health topic pages” which list links to available materials relevant to irritable bowel syndrome. To access this system, log on to http://www.nlm.nih.gov/medlineplus/healthtopics.html. From there you can either search using the alphabetical index or browse by broad topic areas. Recently, MEDLINEplus listed the following when searched for “irritable bowel syndrome”:

Summary: In this fact sheet, the author explores the pathophysiologic (disease process) links between the brain, motility, and sensation in irritable bowel syndrome (IBS). Current available data suggest that investigators and clinicians need to be dissuaded from approaching IBS as though it was a single disorder in all patients, or as though only one mechanism is responsible for development of symptoms. The author stresses the importance of integrated rather than reductionist approaches to research, diagnosis, and management of IBS. The author concludes that motor and sensory functions in the human bowel are intimately linked to higher and lower centers in the brain.

is a chronic condition that can be controlled, but is rarely cured. The brochure focuses on the causes of the illness and on strategies for easing the pain. In most cases, people with IBS can alleviate their symptoms by carefully monitoring their diets, managing stress, and maintaining a regular exercise program. The best way to control the associated muscle spasms is to increase the amount of bulk in the intestinal tract by increasing the amount of fiber in the diet. Fiber makes stools bulkier and softer so the colon does not have to work as hard. The increased bulk decreases the intensity and frequency of contractions and promotes a smoother passage through the intestine. The brochure lists specific strategies for increasing fiber in the diet. The brochure also briefly discusses the role of stress in the management of IBS. The brochure is illustrated with full-color photographs. •

[email protected]. Website: www.iffgd.org. PRICE: Free for members; $1.00 for nonmembers; plus shipping and handling. Order number: 101IBS. Summary: This brochure describes irritable bowel syndrome (IBS), a disturbance of intestinal function with symptoms of abdominal discomfort, bloating, and abnormal bowel movements. Diarrhea may often alternate with constipation. The typical features of IBS are recognizable to a physician, but need not all be present and may appear with some variation in different patients. The most important step in diagnosis is to rule out other diseases; this is done through a detailed history, physical examination, laboratory tests, x-rays, and endoscopy. Although the cause of IBS is not known, symptoms appear to be the result of increased sensitivity to distension of the gastrointestinal (GI) tract by gas or fecal material and a tendency for the bowel to be overly reactive to almost anything: eating, stress, emotional arousal, or gaseous distension. Lactose (milk sugar) intolerance can have similar symptoms to IBS, and while they can occur at the same time in a patient, they are different problems. The brochure discusses remissions and prognosis, the causes of bloating and gas, colitis and how it differs from IBS, treatment options, the impact of the menstrual cycle on IBS symptoms, and the relationship of stress and IBS. Treatment options discussed include evaluation of stress level and diet, diet therapy (increasing dietary fiber, avoiding laxatives, reducing trigger foods),

lifestyle changes, drug therapy, biofeedback, and psychological counseling. The brochure summarizes seven strategies for coping with IBS. The brochure includes a brief description of the International Foundation for Functional Gastrointestinal Disorders. 1 figure. •

Summary: This brochure offers a user friendly approach to understanding and coping with irritable bowel syndrome (IBS). The brochures stresses the importance of consulting a doctor for diagnosis, because symptoms similar to those of IBS can sometimes be caused by other more serious bowel conditions. IBS is the digestive tract's abnormal reaction to the stresses and strains of daily life, as well as to the routine activity of processing food. The brochure reviews normal digestion, including the role of the esophagus, stomach, small intestine, colon, sigmoid colon, and rectum. The symptoms of abdominal pain, constipation, and diarrhea are typical in patients with IBS. With IBS, the natural motility of the bowel muscle is disrupted; motility is the rhythmic wave like motion the bowel makes to move body waste along. Tension, eating, smoking, and alcohol all can alter normal motility. Treatment programs can include medication, changes in the diet, and lifestyle modifications to reduce stress (including exercise, biofeedback meditation, and counseling or support groups). The brochure stresses that continued medical followup is essential to monitor the success of the treatment program. Each concept in the brochure is illustrated with cartoon type line drawings featuring patients and a group of elf characters who are shown as the inner workings of the digestive tract.

PRICE: Single copy free. Summary: This brochure provides basic information about irritable bowel syndrome (IBS), a chronic digestive disease characterized by abdominal pain, diarrhea, and constipation. Other common symptoms are indigestion, nausea, gas, and bloating. The symptoms are usually intermingled to varying extents so that all patients' symptoms are relatively unique to them. Although IBS is not life threatening, accurate diagnosis and subsequent treatment are vital. Diagnostic tests, including a full patient history and colonscopy, can determine if there is a structural abnormality or a functional disorder like IBS. The brochure focuses on the use of diet therapy for managing IBS, including the use of increased dietary fiber intake. Fiber is a general term for food which is not absorbed into the system and which stays in the stool, thereby increasing the stool bulk. The author emphasizes the use of fiber supplements, such as Konsyl (the manufacturer of which is the producer of this brochure). One sidebar comments on the impact of the nervous system on the digestive tract. The brochure is illustrated with full color drawings and photographs. 3 figures.

Summary: This chapter, from a book of instructions for geriatric patients, provides a basic information sheet on irritable colon syndrome or irritable bowel syndrome (IBS). IBS can affect persons of any age. Patients commonly experience long periods that are free of symptoms, punctuated by attacks of the problem that may last for days, weeks, or occasionally months. While stress seems to initiate the attack, the author emphasizes that it is does not so much cause the underlying problem as make it slightly worse so that it becomes apparent. IBS presents as a change in bowel habit, most often diarrhea. Treatment involves using medications to attempt to normalize the digestive tract function. Addition of a fiber supplement to the diet often benefits patients with IBS. The information sheet concludes by reminding readers to contact their health care provider if they have any change in their bowel habits. The instructions are designed to supplement and reinforce physician instructions to their patients. (AA-M).

[email protected]. Website: www.iffgd.org. PRICE: $0.50. Summary: This fact sheet describes and compares the incidence and characteristics of functional dyspepsia and irritable bowel syndrome (IBS). Functional dyspepsia is characterized by chronic or recurrent pain or discomfort centered in the upper abdomen, with no evidence of organic disease or structural or biochemical abnormality. The authors describe three types of functional dyspepsia: ulcer-like, dysmotility like, and unspecified. Dyspepsia occurs in about 30 percent of adults; about half that many have functional dyspepsia. Functional dyspepsia can be treated with changes in diet or with medications. IBS is a functional bowel disorder that can include chronic symptoms of abdominal pain, constipation, bloating of the abdomen, and diarrhea. IBS is very common, appearing in as many as 15 to 20 percent of people in Western countries. Education and changes in diet and lifestyle are often effective in managing relatively mild symptoms. A first step toward individual diet modification is to identify and avoid

foods that make symptoms worse. Medications may be helpful for those with more severe symptoms. (AA-M). •

[email protected]. Website: www.iffgd.org. PRICE: $0.50. Summary: This fact sheet focuses on the gynecological and bladder aspects of irritable bowel syndrome (IBS) in women. The author reports on research that found women with IBS tended to suffer more from painful periods (menstruation), noticed that their IBS symptoms were worse at the time of their periods, and frequently experienced pain during or after sexual intercourse. The sexual pain resembled bowel pain and often came on some time after intercourse, sometimes as late as the next day. The author encourages patients and their partners to become educated about this aspect of IBS in order to reduce stress on the patient. The author discusses the differential diagnosis of IBS from a gynecological perspective, including pelvic inflammatory disease (PID), endometriosis, and gynecological cancer. The author calls for greater collaboration between gastroenterologists and gynecologists when treating patients with lower abdominal pain. The fact sheet also briefly describes the bladder symptoms that are most often seen in patients with IBS. These symptoms include frequency in passing urine, urgency, and sometimes a degree of incontinence. The author cautions that treating supposed urinary tract infections with antibiotics can make the IBS worse and recommends only treating cystitis when it is proven on urine culture. The author concludes by encouraging readers to educate themselves about the possible nongastrointestinal aspects of IBS and to proceed very cautiously when offered surgical answers to their problems.

232 Irritable Bowel Syndrome
Summary: This newsletter article describes gut motility in both normal health and in irritable bowel syndrome. Gut motility is defined as the stretching and contractions of the muscle in the wall of the stomach and bowel. These movements enable the food to progress along the digestive tract while at the same time ensuring the absorption of the important nutrients. Topics include the normal movements of the digestive tract, diagnostic tests that measure these movements of the gut, the types of contraction in the gut, motility in the stomach, small bowel and large bowel (colon), the production of intestinal gas, disorders affecting the motility of the digestive tract, irritable bowel syndrome (IBS), the causes of IBS (including trigger factors), the complications associated with uncoordinated or abnormally high pressure contractions, impairment of propulsive activity, excessive numbers of contractions, delayed or accelerated transit through the intestines, the role of mental stress in IBS symptoms, and the different methods of treating the symptoms of IBS. •

Summary: This patient education brochure helps readers understand irritable bowel syndrome (IBS) and how they can control the symptoms it may cause. In IBS, the intestines squeeze too hard or not hard enough and cause food to move too fast or too slowly through the gastrointestinal (GI) tract. IBS can cause diarrhea, constipation, or both. The symptoms may get worse when the patient experiences stress, including that associated with travel, social events, menstrual cycles, or a change in daily routine. The brochure outlines diagnostic and treatment options, the role of dietary fiber, the impact of diet on IBS symptoms, the role of milk and milk products and the issue of lactose intolerance, managing stress, and drug therapy. The brochure notes that because IBS is a

We can only recommend this route, therefore, for relatively rare or specific disorders, or when using highly targeted searches. To use the NIH search utility, visit the following Web page: http://search.nih.gov/index.html. Additional Web Sources A number of Web sites are available to the public that often link to government sites. These can also point you in the direction of essential information. The following is a representative sample: •

Finding Associations There are several Internet directories that provide lists of medical associations with information on or resources relating to irritable bowel syndrome. By consulting all of associations listed in this chapter, you will have nearly exhausted all sources for patient associations concerned with irritable bowel syndrome. The National Health Information Center (NHIC) The National Health Information Center (NHIC) offers a free referral service to help people find organizations that provide information about irritable bowel syndrome. For more information, see the NHIC’s Web site at http://www.health.gov/NHIC/ or contact an information specialist by calling 1-800-336-4797. Directory of Health Organizations The Directory of Health Organizations, provided by the National Library of Medicine Specialized Information Services, is a comprehensive source of information on associations. The Directory of Health Organizations database can be accessed via the Internet at http://www.sis.nlm.nih.gov/Dir/DirMain.html. It is composed of two parts: DIRLINE and Health Hotlines.
236 Irritable Bowel Syndrome
The DIRLINE database comprises some 10,000 records of organizations, research centers, and government institutes and associations that primarily focus on health and biomedicine. To access DIRLINE directly, go to the following Web site: http://dirline.nlm.nih.gov/. Simply type in “irritable bowel syndrome” (or a synonym), and you will receive information on all relevant organizations listed in the database. Health Hotlines directs you to toll-free numbers to over 300 organizations. You can access this database directly at http://www.sis.nlm.nih.gov/hotlines/. On this page, you are given the option to search by keyword or by browsing the subject list. When you have received your search results, click on the name of the organization for its description and contact information. The Combined Health Information Database Another comprehensive source of information on healthcare associations is the Combined Health Information Database. Using the “Detailed Search” option, you will need to limit your search to “Organizations” and “irritable bowel syndrome”. Type the following hyperlink into your Web browser: http://chid.nih.gov/detail/detail.html. To find associations, use the drop boxes at the bottom of the search page where “You may refine your search by.” For publication date, select “All Years.” Then, select your preferred language and the format option “Organization Resource Sheet.” Type “irritable bowel syndrome” (or synonyms) into the “For these words:” box. You should check back periodically with this database since it is updated every three months. The National Organization for Rare Disorders, Inc. The National Organization for Rare Disorders, Inc. has prepared a Web site that provides, at no charge, lists of associations organized by health topic. You can access this database at the following Web site: http://www.rarediseases.org/search/orgsearch.html. Type “irritable bowel syndrome” (or a synonym) into the search box, and click “Submit Query.”

APPENDIX C. FINDING MEDICAL LIBRARIES Overview In this Appendix, we show you how to quickly find a medical library in your area.
Preparation Your local public library and medical libraries have interlibrary loan programs with the National Library of Medicine (NLM), one of the largest medical collections in the world. According to the NLM, most of the literature in the general and historical collections of the National Library of Medicine is available on interlibrary loan to any library. If you would like to access NLM medical literature, then visit a library in your area that can request the publications for you.24
Finding a Local Medical Library The quickest method to locate medical libraries is to use the Internet-based directory published by the National Network of Libraries of Medicine (NN/LM). This network includes 4626 members and affiliates that provide many services to librarians, health professionals, and the public. To find a library in your area, simply visit http://nnlm.gov/members/adv.html or call 1-800-338-7657.
Medical Libraries in the U.S. and Canada In addition to the NN/LM, the National Library of Medicine (NLM) lists a number of libraries with reference facilities that are open to the public. The following is the NLM’s list and includes hyperlinks to each library’s Web site. These Web pages can provide information on hours of operation and other restrictions. The list below is a small sample of

[NIH] Activities of Daily Living: The performance of the basic activities of self care, such as dressing, ambulation, eating, etc., in rehabilitation. [NIH] Adaptation: 1. The adjustment of an organism to its environment, or the process by which it enhances such fitness. 2. The normal ability of the eye to adjust itself to variations in the intensity of light; the adjustment to such variations. 3. The decline in the frequency of firing of a neuron, particularly of a receptor, under conditions of constant stimulation. 4. In dentistry, (a) the proper fitting of a denture, (b) the degree of proximity and interlocking of restorative material to a tooth preparation, (c) the exact adjustment of bands to teeth. 5. In microbiology, the adjustment of bacterial physiology to a new environment. [EU] Adenine: A purine base and a fundamental unit of adenine nucleotides. [NIH] Adenosine: A nucleoside that is composed of adenine and d-ribose. Adenosine or adenosine derivatives play many important biological roles in addition to being components of DNA and RNA. Adenosine itself is a neurotransmitter. [NIH] Adhesions: Pathological processes consisting of the union of the opposing surfaces of a wound. [NIH] Adrenal Cortex: The outer layer of the adrenal gland. It secretes mineralocorticoids, androgens, and glucocorticoids. [NIH] Adrenal Medulla: The inner part of the adrenal gland; it synthesizes, stores and releases catecholamines. [NIH] Adrenergic: Activated by, characteristic of, or secreting epinephrine or substances with similar activity; the term is applied to those nerve fibres that liberate norepinephrine at a synapse when a nerve impulse passes, i.e., the sympathetic fibres. [EU]
248 Irritable Bowel Syndrome
Adverse Effect: An unwanted side effect of treatment. [NIH] Aerobic: In biochemistry, reactions that need oxygen to happen or happen when oxygen is present. [NIH] Aerobic Exercise: A type of physical activity that includes walking, jogging, running, and dancing. Aerobic training improves the efficiency of the aerobic energy-producing systems that can improve cardiorespiratory endurance. [NIH] Aerophagia: A condition that occurs when a person swallows too much air. Causes gas and frequent belching. [NIH] Afferent: Concerned with the transmission of neural impulse toward the central part of the nervous system. [NIH] Affinity: 1. Inherent likeness or relationship. 2. A special attraction for a specific element, organ, or structure. 3. Chemical affinity; the force that binds atoms in molecules; the tendency of substances to combine by chemical reaction. 4. The strength of noncovalent chemical binding between two substances as measured by the dissociation constant of the complex. 5. In immunology, a thermodynamic expression of the strength of interaction between a single antigen-binding site and a single antigenic determinant (and thus of the stereochemical compatibility between them), most accurately applied to interactions among simple, uniform antigenic determinants such as haptens. Expressed as the association constant (K litres mole -1), which, owing to the heterogeneity of affinities in a population of antibody molecules of a given specificity, actually represents an average value (mean intrinsic association constant). 6. The reciprocal of the dissociation constant. [EU] Age Groups: Persons classified by age from birth (infant, newborn) to octogenarians and older (aged, 80 and over). [NIH] Aged, 80 and Over: A person 80 years of age and older. [NIH] Agonist: In anatomy, a prime mover. In pharmacology, a drug that has affinity for and stimulates physiologic activity at cell receptors normally stimulated by naturally occurring substances. [EU] Agoraphobia: Obsessive, persistent, intense fear of open places. [NIH] Airway: A device for securing unobstructed passage of air into and out of the lungs during general anesthesia. [NIH] Akathisia: 1. A condition of motor restlessness in which there is a feeling of muscular quivering, an urge to move about constantly, and an inability to sit still, a common extrapyramidal side effect of neuroleptic drugs. 2. An inability to sit down because of intense anxiety at the thought of doing so. [EU] Alertness: A state of readiness to detect and respond to certain specified small changes occurring at random intervals in the environment. [NIH] Alexia: The inability to recognize or comprehend written or printed words. [NIH] Algorithms: A procedure consisting of a sequence of algebraic formulas and/or logical steps to calculate or determine a given task. [NIH] Alimentary: Pertaining to food or nutritive material, or to the organs of digestion. [EU] Alkaline: Having the reactions of an alkali. [EU] Alkaloid: A member of a large group of chemicals that are made by plants and have nitrogen in them. Some alkaloids have been shown to work against cancer. [NIH] Allergen: An antigenic substance capable of producing immediate-type hypersensitivity (allergy). [EU] Allergic Rhinitis: Inflammation of the nasal mucous membrane associated with hay fever;
Dictionary 249
fits may be provoked by substances in the working environment. [NIH] Allylamine: Possesses an unusual and selective cytotoxicity for vascular smooth muscle cells in dogs and rats. Useful for experiments dealing with arterial injury, myocardial fibrosis or cardiac decompensation. [NIH] Aloe: A genus of the family Liliaceae containing anthraquinone glycosides such as aloinemodin or aloe-emodin (emodin). [NIH] Alpha-1: A protein with the property of inactivating proteolytic enzymes such as leucocyte collagenase and elastase. [NIH] Alternative medicine: Practices not generally recognized by the medical community as standard or conventional medical approaches and used instead of standard treatments. Alternative medicine includes the taking of dietary supplements, megadose vitamins, and herbal preparations; the drinking of special teas; and practices such as massage therapy, magnet therapy, spiritual healing, and meditation. [NIH] Amenorrhea: Absence of menstruation. [NIH] Amine: An organic compound containing nitrogen; any member of a group of chemical compounds formed from ammonia by replacement of one or more of the hydrogen atoms by organic (hydrocarbon) radicals. The amines are distinguished as primary, secondary, and tertiary, according to whether one, two, or three hydrogen atoms are replaced. The amines include allylamine, amylamine, ethylamine, methylamine, phenylamine, propylamine, and many other compounds. [EU] Amino Acid Sequence: The order of amino acids as they occur in a polypeptide chain. This is referred to as the primary structure of proteins. It is of fundamental importance in determining protein conformation. [NIH] Amino Acids: Organic compounds that generally contain an amino (-NH2) and a carboxyl (COOH) group. Twenty alpha-amino acids are the subunits which are polymerized to form proteins. [NIH] Amino Acids: Organic compounds that generally contain an amino (-NH2) and a carboxyl (COOH) group. Twenty alpha-amino acids are the subunits which are polymerized to form proteins. [NIH] Amitriptyline: Tricyclic antidepressant with anticholinergic and sedative properties. It appears to prevent the re-uptake of norepinephrine and serotonin at nerve terminals, thus potentiating the action of these neurotransmitters. Amitriptyline also appears to antaganize cholinergic and alpha-1 adrenergic responses to bioactive amines. [NIH] Ammonia: A colorless alkaline gas. It is formed in the body during decomposition of organic materials during a large number of metabolically important reactions. [NIH] Amphetamines: Analogs or derivatives of amphetamine.

Complement activation occurs by two different sequences, the classic and alternative pathways. The proteins of the classic pathway are termed 'components of complement' and are designated by the symbols C1 through C9. C1 is a calcium-dependent complex of three distinct proteins C1q, C1r and C1s. The proteins of the alternative pathway (collectively referred to as the properdin system) and complement regulatory proteins are known by semisystematic or trivial names. Fragments resulting from proteolytic cleavage of complement proteins are designated with lower-case letter suffixes, e.g., C3a. Inactivated fragments may be designated with the suffix 'i', e.g. C3bi. Activated components or complexes with biological activity are designated by a bar over the symbol e.g. C1 or C4b,2a. The classic pathway is activated by the binding of C1 to classic pathway activators, primarily antigen-antibody complexes containing IgM, IgG1,
Dictionary 263
IgG3; C1q binds to a single IgM molecule or two adjacent IgG molecules. The alternative pathway can be activated by IgA immune complexes and also by nonimmunologic materials including bacterial endotoxins, microbial polysaccharides, and cell walls. Activation of the classic pathway triggers an enzymatic cascade involving C1, C4, C2 and C3; activation of the alternative pathway triggers a cascade involving C3 and factors B, D and P. Both result in the cleavage of C5 and the formation of the membrane attack complex. Complement activation also results in the formation of many biologically active complement fragments that act as anaphylatoxins, opsonins, or chemotactic factors.
