AIM To investigate the relationship between selective serotonin reuptake inhibitor(SSRI)use and the subsequent development of irritable bowel syndrome(IBS).METHODS This retrospective,observational,population-based cohort study collected data from Taiwan’s National Health Insurance Research Database.A total of 19653patients newly using SSRIs and 78612 patients not using SSRIs,matched by age and sex at a ratio of 1:4, were enrolled in the study from January 1,2000 to December 31,2010.The patients were followed until IBS diagnosis,withdrawal from the National Health Insurance system,or the end of 2011.We analyzed the effects of SSRIs on the risk of subsequent IBS using Cox proportional hazards regression models.RESULTS A total of 236 patients in the SSRI cohort(incidence,2.17/1000 person-years)and 478 patients in the comparison cohort(incidence,1.04/1000 person-years)received a new diagnosis of IBS.The mean follow-up period from SSRI exposure to IBS diagnosis was 2.05years.The incidence of IBS increased with advancing age.Patients with anxiety disorders had a significantly increased adjusted hazard ratio(a HR)of IBS(a HR=1.33,95%CI:1.11-1.59,P=0.002).After adjusting for sex,age,urbanization,family income,area of residence,occupation,the use of anti-psychotics and other comorbidities,the overall a HR in the SSRI cohort compared with that in the comparison cohort was1.74(95%CI:1.44-2.10;P<0.001).The cumulative incidence of IBS was higher in the SSRI cohort than in the non-SSRI cohort(log-rank test,P<0.001).CONCLUSION SSRI users show an increased risk of subsequent diagnosis of IBS in Taiwan. 展开更多

The use of non-steroidal anti-inflammatory drugs(NSAIDs) is widespread worldwide thanks to their analgesic, anti-inflammatory and antipyretic effects. However, even more attention is placed upon the recurrence of digestive system complications in the course of their use. Recent data suggests that the complications of the lower gastro-intestinal tract may be as frequent and severe as those of the upper tract. NSAIDs enteropathy is due to enterohepatic recycling of the drugs resulting in a prolonged and repeated exposure of the intestinal mucosa to the compound and its metabolites. Thus leading to so-called topical effects, which, in turn, lead to an impairment of the intestinal barrier. This process determines bacterial translocation and toxic substances of intestinal origin in the portal circulation, leading to an endotoxaemia. This condition could determine a liver inflammatory response and might promote the development of nonalcoholic steatohepatitis, mostly in patients with risk factors such as obesity, metabolic syndrome and a high fat diet, which may induce a small intestinal bacterial overgrowth and dysbiosis. This alteration of gut microbiota may contribute to nonalcoholic fatty liver disease and its related disorders in two ways: firstly causing a malfunction of the tight junctions that play a critical role in the increase of intestinal permeability, and then secondly leading to the development of insulin resistance, body weight gain, lipogenesis, fibrogenesis and hepatic oxidative stress. 展开更多
