Our objective was to obtain national data of the estimated prevalence, sociodemographic relationships, and health impact of persons with functional gastrointestinal disorders. We surveyed a stratified probability random sample of U.S. householders selected from a data base of a national market firm (National Family Opinion, Inc.). Questions were asked about bowel symptoms, sociodemographic associations, work absenteeism, and physician visits. The sampling frame was constructed to be demographically similar to the U.S. householder population based on geographic region, age of householder, population density, household income, and household size. Of 8250 mailings, 5430 were returned suitable for analysis (66% response). The survey assessed the prevalence of 20 functional gastrointestinal syndromes based on fulfillment of multinational diagnostic (Rome) criteria. Additional variables studied included: demographic status, work absenteeism, health care use, employment status, family income, geographic area of residence, population density, and number of persons in household. For this sample, 69% reported having at least one of 20 functional gastrointestinal syndromes in the previous three months. The symptoms were attributed to four major anatomic regions: esophageal (42%), gastroduodenal (26%), bowel (44%), and anorectal (26%), with considerable overlap. Females reported greater frequencies of globus, functional dysphagia, irritable bowel syndrome, functional constipation, functional abdominal pain, functional biliary pain and dyschezia; males reported greater frequencies of aerophagia and functional bloating. Symptom reporting, except for incontinence, declines with age, and low income is associated with greater symptom reporting. The rate of work/school absenteeism and physician visits is increased for those having a functional gastrointestinal disorder. Furthermore, the greatest rates are associated with those having gross fecal incontinence and certain more painful functional gastrointestinal disorders such as chronic abdominal pain, biliary pain, functional dyspepsia and IBS. Preliminary information on the prevalence, socio-demographic features and health impact is provided for persons who fulfill diagnostic criteria for functional gastrointestinal disorders.

A study of the abdominal/gastrointestinal symptom panorama in relation to socio-economic factors and health care consumption in the general population was performed in Osthammar, Sweden. A postal questionnaire was sent to a representative sample of the adult population (n = 1260). The response rate was 87%. The responders with symptoms (52.1%) subjectively rated their illness on visual analogue scales. All responders were classified as asymptomatic or having 'minor' or 'major' abdominal symptoms. Those having dyspepsia, reflux or irritable bowel syndrome were also ranked as 'minors' or 'majors'. The proportion of subjects with abdominal/gastrointestinal complaints decreased with age, mainly due to a decrease of 'major' symptoms. Also, the proportion of complainers increased among the more educated. Those on sick leave and students had more and worse symptoms than the others, despite the former seldom stating abdominal discomfort as the main reason for sick listing. Fifty-five per cent of all persons reporting abdominal/gastrointestinal symptoms had at some time consulted a doctor because of such complaints, the proportion increasing with severity, as did drug consumption and the rate of previous abdominal operations, with appendectomy as an exception. The results show that it is possible to rank the illness along a severity dimension among persons with abdominal/gastrointestinal complaints in epidemiological research.

Patients with non-cardiac chest pain (NCCP) (n = 387) and cardiac chest pain (CCP) (n = 93) were compared with community controls (n = 81), using a symptom questionnaire that assessed the presence of irritable bowel syndrome (IBS), functional dyspepsia, and oesophageal dysfunction and chest pain characteristics. A significantly (p < 0.05) increased prevalence of symptoms compatible with IBS occurred in NCCP patients when compared with those with CCP and with controls. Dysphagia was more frequent in both those with non-cardiac and cardiac chest pain than in controls; this was not apparent, however, when patients with concomitant IBS were excluded. The presence of oesophageal or gastrointestinal symptoms did not enable discrimination with regard to the chest pain characteristics. We conclude that unselected referred patients with documented NCCP are more likely to have IBS and that the presence of oesophageal symptoms such as dysphagia may merely reflect the spectrum of the 'irritable gut'.

Many patients with dyspepsia do not have peptic ulceration or other organic disease that explains their symptoms. The etiology of nonulcer dyspepsia is not established, and its treatment remains empiric. A careful clinical evaluation can usually rule out other disorders, such as gastroesophageal reflux disease and irritable bowel syndrome, and can identify patients who require immediate investigation and those who can safely receive empiric therapy with antacids or a histamine H2-receptor antagonist. If diagnostic investigation is indicated, endoscopy is the procedure of choice. The physician can then classify patients with documented nonulcer dyspepsia on the basis of symptoms, which may guide therapy. Many patients with nonulcer dyspepsia respond to reassurance, explanation, dietary modifications and avoidance of precipitating factors.

Cisapride is a substituted benzamide compound that stimulates motor activity in all segments of the gastrointestinal tract by enhancing the release of acetylcholine from the enteric nervous system. Cisapride is administered orally in the treatment of gastro-oesophageal reflux disease, functional dyspepsia, gastroparesis, chronic intestinal pseudo-obstruction syndromes and chronic constipation. In gastro-oesophageal reflux disease in both adults and children, cisapride provides symptomatic improvement and mucosal healing. Long term treatment with cisapride is effective in the prevention of relapse of oesophagitis. Cisapride improves gastric emptying rates and improves symptoms in patients with gastroparesis of various origins. Unlike domperidone and metoclopramide, long term administration of cisapride seems to result in persistently enhanced gastric emptying. Cisapride is also effective in improving symptoms in patients with functional dyspepsia. In comparative studies in patients with functional dyspepsia, cisapride was at least as effective as metoclopramide, domperidone, clebopride, ranitidine and cimetidine. Cisapride increases stool frequency and reduces laxative consumption in patients with idiopathic constipation. Severe cases of slow transit constipation seem refractory to cisapride. Clinical studies also indicate that cisapride might be effective in the treatment of chronic intestinal pseudo-obstruction, postoperative ileus, peptic ulcer and irritable bowel syndrome. Further clinical studies are warranted to define the role of cisapride in these conditions. The dosage of cisapride ranges from 5mg 3 times daily to 20mg twice daily. Cisapride is generally well tolerated, both during short and long term treatment. In children, cisapride is also well tolerated in doses of 0.2 to 0.3 mg/kg, 3 to 4 times daily.(ABSTRACT TRUNCATED AT 250 WORDS)

Increased numbers of psychiatric diagnoses and increased levels of psychological distress are seen in the majority of medical clinic patients with gastrointestinal motility disorders. In IBS, psychological symptoms are believed to be comorbid conditions, which do not cause the motility disorder but which do influence the patient's decision to consult a physician. In functional dyspepsia, psychological symptoms are present in many patients, but their role is not known; the available data suggest that psychological symptoms do not predict which patients will consult a physician. Among constipated patients, anxiety is believed to contribute to the development and course of pelvic floor dyssynergia by increasing pelvic floor muscle tension. Constipated patients without physiologic abnormalities to explain their constipation appear to have more psychological symptoms than those with delayed colonic transit, but there is significant psychological distress even in patients with slow transit constipation. Psychological symptoms do not seem to predict which constipated patients will consult a physician. There is an increased incidence of psychiatric diagnoses in patients with esophageal motility disorders as well, but the role that these psychological symptoms play in the course of the disorder is not known. Patients with the most common gastrointestinal motility disorders, IBS and dyspepsia, report experiencing more stressful life events, and IBS patients appear to show a greater increase in gastrointestinal symptoms when exposed to stressors. Laboratory studies document that acute psychological stressors do alter gastric, small bowel, and colonic motility, and patients with IBS appear to show a greater change in colonic and ileal motility with stress than healthy controls. Greater reactivity has not been demonstrated for the esophagus or stomach, however, and it has not been demonstrated for other gastrointestinal motility disorders. A characteristic of many patients who consult gastroenterologists for IBS and other motility disorders is a tendency to report multiple somatic complaints (including many nongastrointestinal complaints) and to overuse medical resources. This pattern of behavior is referred to as somatization or abnormal illness behavior. One source of abnormal illness behavior is childhood social learning, which occurs (1) when parents provide gifts or special privileges to a child who reports somatic symptoms or (2) when parents model abnormal illness behaviors themselves.

This multicenter, double-blind, placebo-controlled, parallel-group, randomized study assessed the efficacy, safety, and tolerability of a novel CCK-B antagonist CI-988 in the treatment of generalized anxiety disorder (GAD). Patients received placebo or CI-988 (300 mg/day, thrice daily) for 4 weeks. Patients with a primary diagnosis of GAD according to DSM-III-R criteria were randomized. The study design included a 1- to 2-week single-blind placebo baseline phase, followed by a 4-week double-blind treatment phase. Efficacy was measured weekly by Hamilton Rating Scale for Anxiety (HAM-A), Clinical Global Impressions of Severity and Change, UCLA-Multi Dimensional Anxiety Scale, and Hamilton Rating Scale for Depression. Patients were also evaluated to determine whether they met criteria for irritable bowel syndrome (IBS) at screening and were evaluated with a gastrointestinal visual analog scale at each visit. Eighty-eight patients were randomized to CI-988 (N = 45) and placebo (N = 43) at three centers. CI-988 did not demonstrate an anxiolytic effect superior to placebo in this clinical trial. There was no significant difference in mean change in HAM-A total between placebo (-7.73) and CI-988 (-8.64). However, a significant treatment-by-center interaction and a highly variable placebo response rate among the three centers limit the interpretation of the results. CI-988 did not have an effect on symptoms of IBS other than diarrhea, which worsened in patients with IBS. Other than a higher incidence of some gastrointestinal symptoms (diarrhea, dyspepsia, flatulence, and nausea), CI-988 was well tolerated. Results suggest that testing higher oral doses of CI-988 may be warranted.

Gastrointestinal disorders are common in the general population, with annual prevalence figures ranging from 20% for irritable bowel syndrome to over 40% for dyspepsia. Less than one-third of patients consult general practitioners for these problems, and anxiety about serious disease and cancer are as important in the decision to consult as symptom severity. Gastrointestinal disorders have significant socioeconomic effects in the community, and account for 10% of the work of general practitioners in the UK. The health economics implications of management in primary care relate principally to the costs of investigation and therapy, notably antisecretory drugs, endoscopy, radiology and specialist referral. Although guidelines based on evidence and agreed between primary and secondary care physicians offer an attractive approach to rationalizing the use of resources, there is at present little health service research evidence on which to base important decisions. For example, in dyspepsia, the role of Helicobacter pylori identification and eradication in an overall management strategy in primary care has yet to be defined. An exploration of the clinical economics of gastrointestinal disorders in general practice raises a number of research questions, which will require the attention of both generalists and specialists.

The aim of the present study was to determine the degree of pain localization and frequency of nocturnal pain in duodenal ulcer and other causes of chronic upper abdominal pain. These parameters were prospectively recorded in a consecutive series of 1615 patients with chronic upper abdominal pain presenting to one gastroenterologist. The proportion of patients who were able to localize the site of their pain using a single finger was 13% for duodenal ulcer, 5% for gastric ulcer, 17% for biliary disease, 7% for functional dyspepsia and 8% for irritable bowel syndrome. The numbers of subjects with the above diagnoses who experienced nocturnal pain were 63, 63, 51, 41 and 58%, respectively. The sensitivity, specificity, positive predictive value and negative predictive value for duodenal ulcer were 13, 92, 14 and 91%, respectively, for localized pain; 63, 50, 11 and 93%, respectively, for nocturnal pain occurrence; and 9, 96, 20 and 90%, respectively, if the pain was both localized and nocturnal. If the pain was neither localized nor nocturnal, the corresponding values for the absence of duodenal ulcer disease were 49, 68, 93 and 13%, respectively. The pain of duodenal ulcer was therefore more likely to be nocturnal and well localized compared with pain from other causes. However, while the absence of these features made duodenal ulcer unlikely, their presence was less helpful in the diagnostic process.

With the aim to assess the clustering of abdominal symptoms in a random population, data from a cohort study of a 70 year old Danish population were analysed. The cohort comprised 1,119 subjects of which 72% participated in a primary study and 91% of the survivors in a similar study five years later. The following clusters of symptoms were constantly associated. One group constituted abdominal distension, borborygmi, altering stool consistency and number of bowel movements. Pain relieved by bowel movement was associated with this cluster. Nausea and vomiting comprised another cluster. Heartburn/acid regurgitation did not show a consistent association to any other symptoms and may be considered as a cluster of it own. Pain characteristics traditionally related to upper dyspepsia did not specifically relate to any cluster. It is concluded that, in this 70-year-old population abdominal symptoms occur in clusters comparable to clusters in younger populations. The clusters, however, does not totally confirm the traditional concept of Upper Dyspepsia and Irritable Bowel Syndrome.
