OBJECTIVES-Functional gastrointestinal disorders (FGIDs) comprise a constellation of symptoms that have no identifiable structural or biochemical abnormality. In view of the lack of data from large-scale population-based studies evaluating the effects of these disorders on survival, we aimed to examine whether FGIDs are associated with impaired survival. 1988 and 1993, valid self-report questionnaires that recorded gastrointestinal symptoms required for the diagnosis of irritable bowel syndrome (IBS), chronic constipation, chronic diarrhea, dyspepsia, and abdominal pain were mailed to randomly selected cohorts of Olmsted County, Minnesota residents. Minnesota administrative death records were used to identify which of the survey respondents had died over the follow-up period (through April 2008). The association between survival and each FGID was assessed using proportional hazards regression models with univariate and adjusted hazard ratios (HRs, 95% confidence intervals (CIs)), adjusting for age at time of survey, gender, smoking, alcohol, marital status, and Charlson Comorbidity Index (CCI). METHODS-BetweenRESULTS-Of the 5,262 randomly selected eligible subjects who received a questionnaire, a total of 4,176 responded to the surveys (overall response rate 79%). From these respondents, 243 subjects were excluded because of lack of research authorization (or were registered solely at a different medical institution in Olmsted County, MN), resulting in 3,933 eligible subjects for analysis (eligible response rate 75%); 10% reported symptoms of IBS; 16% chronic constipation; 18% chronic diarrhea; 2% dyspepsia; and 15% abdominal pain. At baseline, the mean (s.d.) age was 54 (18) years, and 52% were female. No association with overall survival was detected for IBS (HR = 1.06 (95% CI: 0.86-1.32)), chronic diarrhea (HR = 1.03 (95% CI: 0.90-1.19)), abdominal pain (HR = 1.09 (95%

SUMMARY BackgroundGastro-oesophageal reflux disease (GERD) and irritable bowel syndrome may occur more often than expected by chance, but little community data exists and risk factors are unknown.

The MCDAI strongly predicted the PGA and correlated with a validated measure of quality of life. Several symptoms in addition to diarrhoea are associated with disease severity in MC.

Background Prospective data are lacking to determine if IBS a risk factor for cholecystectomy, or if biliary disease and cholecystectomy predisposes to the development of IBS. Methods Validated symptom surveys sent to cohorts of Olmsted County, MN, (1988–1994) with follow-up in 2003. Medical histories were reviewed to determine any “biliary events” (defined by gallstones or cholecystectomy). Analyses examined: 1) time to a biliary event post initial survey and separately, 2) risk of IBS (Rome II) in those with vs. without a prior biliary event. Results 1908 eligible subjects mailed a follow-up survey. For aim 1) of the 726 without IBS at initial survey, 44 (6.1%) had biliary events during follow up, in contrast to 5 of 93 (5.4%) with IBS at initial survey (HR 0.8, 95% CI 0.3-2.1). For aim 2) of the 59 subjects with a biliary event at initial survey, 10 (17%) reported new IBS on the follow-up survey, while in 682 without a biliary event up to 1.5 years prior to the second survey, 58 (8.5%) reported IBS on follow-up (OR=2.2, 95% CI 1.1-4.6, p=0.03). Conclusion There is an increased risk of new IBS in community subjects who have been diagnosed as having a biliary event.

In this population-based study with over 50,000 person-years of follow-up, reflux symptoms were not associated with worse survival. The vast majority of heartburn sufferers can be reassured of the benign nature of their condition.

By nature of the definition of functional dyspepsia (FD), organic causes have to be ruled out before therapy can be directed. However, in uninvestigated dyspepsia in the absence of alarm features, Helicobacter pylori "test and treat" or an empiric trial of acid suppression therapy for 4 to 8 weeks is reasonable. If alarm symptoms or signs are present, or if the dyspepsia symptoms first occur in those aged greater than 55 years, prompt esophagogastroduodenoscopy is mandatory to exclude serious disease and positively diagnose FD. Empiric acid suppression with H(2)-receptor antagonists or proton-pump inhibitors is superior to placebo in treatment of FD, but those patients with meal-related symptoms are least likely to respond. Helicobacter pylori eradication in FD benefits a minority of cases but is worthwhile, as response may be maintained. There is increasing evidence that some prokinetics may be superior to placebo in treatment of FD, but probably only a minority respond; those with meal-related symptoms may have the best response. Antidepressant therapy may have a place in management of difficult cases, but adequate randomized controlled trials are unavailable.
