Family history of mental illness or alcohol abuse and the irritable bowel syndrome.

ABSTRACT: We have observed that many patients with IBS drink very little alcohol and postulated that this may reflect membership in families affected by alcoholism and mental illness. We aimed to evaluate whether a family history of substance or alcohol abuse, or psychiatric illness, is associated with IBS.A valid GI questionnaire was mailed to a randomly selected population-based cohort to identify IBS and healthy controls. The electronic medical record was reviewed to record the subjects' self-reported personal and family health histories.A total of 2300 subjects responded (response rate 55%; IBS 13%, n=287); 230 subjects with IBS and 318 controls were eligible. Family history of alcohol/substance abuse was reported by 33% of cases and 25% of controls (OR=1.4, 95% CI=1.0-2.1, p=0.06). Family history of psychiatric illness was reported by 37% of cases and 22% of controls (OR=2.0, 95% CI=1.3-2.9, p<0.001). In the absence of a personal history of alcohol use, a family history of alcohol/substance abuse was predictive of IBS status (OR adjusted for age and gender=1.5, 95% CI=1.0-2.3, p=0.05). In the absence of a personal history of alcohol use, reporting both a family history of alcohol/substance abuse and anxiety/depression/mental illness was clearly predictive of IBS status (OR=2.5, 95% CI=1.4-4.5; p<0.005). Substance abuse as a child was associated with an increased risk of IBS (OR=2.3, 95% CI=1.1-4.8; p<0.03).IBS is independently associated with a family history of psychiatric illness and may be linked to a family history of alcohol/substance abuse.

Project description:BackgroundThe intestinal microbiota is thought to be involved in the occurrence of inflammatory bowel disease in remission with irritable bowel syndrome (IBS)-type symptoms, but the specific distinct profile of these bacteria remains unclear. This cross-sectional study aims to investigate the fecal microbiota profiling in patients with these diseases.MethodsFecal samples from 97 subjects, including Crohn's disease patients in remission with IBS-type symptoms (CDR-IBS+) or without IBS-type symptoms (CDR-IBS-), ulcerative colitis patients in remission with IBS-type symptoms (UCR-IBS+) or without IBS-type symptoms (UCR-IBS-), IBS patients and healthy controls, were collected and applied 16S ribosomal DNA (rDNA) gene sequencing. The V4 hypervariable regions of 16S rDNA gene were amplified and sequenced by the Illumina MiSeq platform. The differences in the sample diversity index in groups were analyzed with R software.ResultsThe richness of the intestinal microbiota in the CDR-IBS group was markedly lower than those in the control and IBS groups based on the analysis of observed species and the Chao index (P < 0.05). The observed species index in the CDR-IBS+ group was higher than that in the CDR-IBS- group (median index: 254.8 vs 203, P = 0.036). No difference was found in alpha diversity between UCR patients with IBS-type symptoms and those without related symptoms. At the genus level, the number of Faecalibacterium in CDR patients with IBS-type symptoms increased significantly, while Fusobacterium decreased versus those without such symptoms (mean relative abundance of Faecalibacterium: 20.35% vs 5.18%, P < 0.05; Fusobacterium: 1.51% vs 5.2%, P < 0.05). However, compared with the UCR-IBS- group, the number of Faecalibacterium in the UCR-IBS+ group decreased, while the number of Streptococcus increased, but there was no significant difference in the genus structure. The abundance and composition of the microbiota of IBS patients were not distinct from those of healthy controls.ConclusionsThe IBS-type symptoms in CD patients in remission may be related to an increase in Faecalibacterium and a decrease in Fusobacterium. The IBS-type symptoms in UC patients in remission cannot be explained by changes in the abundance and structure of the intestinal microbiota.
