IBS Criteria (ib + criterion)
Selected AbstractsEpidemiology of irritable bowel syndrome in Asia: Something old, something new, something borrowedJOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 10 2009Kok-Ann Gwee Abstract In this review we have unearthed epidemiological data that; support the ,old' concept of irritable bowel syndrome (IBS) as a disorder of civilization, build a ,new' symptom profile of IBS for Asia, and persuade us against the use of ,borrowed' Western diagnostic criteria and illness models by Asian societies. In the 1960s, IBS was described as a disorder of civilization. Early studies from Asia suggested a prevalence of IBS below 5%. Recent studies from Asia suggest a trend for the more affluent city states like Singapore and Tokyo, to have higher prevalence of 8.6% and 9.8%, respectively, while India had the lowest prevalence of 4.2%. Furthermore, there was a trend among the better educated and more affluent strata of society in several urban Chinese populations for a higher prevalence of IBS, as well as a trend for a higher consultation rate. Across Chinese and Indian predominant populations, a majority of patients with IBS criteria report upper abdominal symptoms such as epigastric pain relieved by defecation, bloating and dyspepsia. Bloating and incomplete evacuation appear to be more important determinants of consultation behavior, than psychological factors. The failure of the Rome criteria to recognize the relationship to meals, may have led to a substantial misclassification of IBS as dyspepsia. The relevance of the Western model of psychological disturbance as a determinant of consultation behavior is questionable because of the accessibility and acceptability of medical consultation for gastrointestinal complaints in many Asian communities.

Olafsdottir Aliment Pharmacol Ther 2010; 32: 670,680 Summary Background, The irritable bowel syndrome (IBS) is a common disorder, but information on its natural history is limited. Aim, To study the performance of four IBS criteria in detecting incidence and stability of categories over a 10-year period. Method, This study was a population-based postal study. Questionnaire was mailed to the same age- and gender-stratified random sample of the Icelandic population aged 18,75 years in 1996 and again in 2006. IBS was estimated by the Manning criteria, Rome II, Rome III, subgroups and self-report. Results, Prevalence of IBS varied according to criteria: Manning showed the highest (32%) and Rome II the lowest (5%). Younger subjects and females were more likely to have IBS. Prevalence was stable over 10 years for all criteria except Rome III. There was a turnover in all IBS subgroups and a strong correlation among IBS, functional dyspepsia and heartburn. Conclusions, The prevalence of the IBS remained stable over a 10-year period with a turnover in symptoms. The study suggests that IBS is a cluster of symptoms that float in time between different IBS categories, functional dyspepsia and heartburn. The irritable bowel syndrome in Iceland is very common and indicates a chronic condition, which poses a heavy burden on the health care system.

JELLEMA Summary Background, Despite the trend towards making a positive diagnosis of irritable bowel syndrome (IBS), many health care providers approach IBS as a diagnosis of exclusion. Aim, To summarize available evidence on the diagnostic performance of symptom-based IBS criteria in excluding organic diseases, and of individual signs and symptoms in diagnosing IBS and to additionally assess the influence of sources of heterogeneity on diagnostic performance. Methods, We searched PubMed and EMBASE and screened references. Studies were selected if the design was a primary diagnostic study; the patients were adults consulting because of non-acute abdominal symptoms; the diagnostic test included an externally validated set of IBS criteria, signs, or symptoms. Data extraction and quality assessment were performed by two reviewers independently. The review adhered to the most recent guidelines as described in the Cochrane Diagnostic Reviewers' Handbook. Results, A total of 25 primary diagnostic studies were included in the review. The performance of symptom-based criteria in the exclusion of organic disease was highly variable. Patients fulfilling IBS criteria had, however, a lower risk of organic diseases than those not fulfilling the criteria. Conclusions, With none of the criteria showing sufficiently homogeneous and favourable results, organic disease cannot be accurately excluded by symptom-based IBS criteria alone. However, the low pre-test probability of organic disease especially among patients who meet symptom-based criteria in primary care argues against exhaustive diagnostic evaluation. We advise validation of the new Rome III criteria in primary care populations. [source] | ||||||||||
