Brief Summary

Inflammatory bowel disease (IBD) is a chronic idiopathic inflammatory condition of the intestine, which results in diarrhea, rectal bleeding, urgency, weight loss and abdominal pain. The natural course of IBD is characterized by activity outbreaks and periods of remission. In most cases, relapses in Crohn's disease (CD) and in ulcerative colitis (UC) are unpredictable and despite effective medical treatment, a degree of subclinical inflammation may persist in the bowel wall, contributing to a significant risk of relapse. In IBD, altered fecal microbiota signatures have been consistently reported which included a reduction in biodiversity with lower proportions of Firmicutes and increases in Proteobacteria and Bacteroidetes phylum members. It is however unclear whether changes in microbial profile including diversity and composition can predict disease relapse in IBD. We hypothesize that fecal microbial signatures in conjunction with fecal calprotectin may play a role in predicting relapse in IBD patients.
