Spectrum of Gastrointestinal Microbiota in Patients With IBS-D Before and After Treatment With VSL#3.

Introduction

The role of the commensal flora in many disease states, including irritable bowel syndrome, inflammatory bowel disease, and even obesity, is now accepted and will undoubtedly lead to new therapeutic strategies. The recently NIH-initiated Human Microbiome Project will allow better understanding of the role of this complex intestinal community in human health and disease. On the clinical side, we are exploring the more common pathogenic bacterial strains in Irritable bowel syndrome patients and use of probiotics in this functional gastrointestinal disease. We are taking support from Genotypic institute, Bangalore for Illumina sequencing facility.

Asian Institute of Gastroenterology, the parent institution, is a 200 bed tertiary care referral hospital providing services to patients with GI diseases, with a daily attendance of 400 out-patients and 200 in-patients. The long term goals of the investigators, involving basic researchers and clinicians, include development of technological resources and applications of biotechnology for use in clinical trials to improve survival rates of patients with GI diseases. The major volume of the outpatient cases comprise of patients with irritable bowel syndrome. Altered GI microbiota may contribute to IBS symptoms and studying dysbiosis in gut microbiota is an important to develop therapy for IBS.
