About this study

The goal of this prospective observational study is to determine if specific microbiome signatures can predict therapeutic responses in adult patients with Crohn's disease (CD), a form of inflammatory bowel disease (IBD), living in British Columbia, Canada. The main questions this study seeks to answer are: 1. Can microbiome signatures across different sample types (fecal, intestinal washings, and intestinal epithelial biopsies) predict response to therapy in CD? 2. How do microbiome profiles differ between active and quiescent CD and non-IBD controls? Researchers will compare microbiome signatures in patients with active and inactive CD as well as non-IBD controls to see if there are any microbial signatures that predict response to therapy. Participants will: 1. Provide fecal and blood samples. 2. Undergo intestinal washings and intestinal epithelial biopsy specimens taken during routine colonoscopy. 3. Participate in a longitudinal follow-up over 12 months to monitor clinical, biochemical, and endoscopic responses to therapy.
