Summary

This study looks at the viruses (called bacteriophages) living in the guts of people with inflammatory bowel disease (IBD) and healthy people. Researchers want to understand how these viruses differ and whether they can be grown in a lab to create a new treatment. The study involves 40 adults (30 with IBD and 10 healthy donors) and only collects stool and blood samples — no treatments are given.

Who is studied

The study is a non-interventional trial aiming to examine the virome/bacteriophages from stool samples of patients with IBD (UC, CD, and PSC-IBD) and compare these with healthy controls (fecal donors). Study participants The study will include 30 patients with IBD: 10 with ulcerative colitis (UC), 10 with Crohn's disease (CD), and 10 with PSC-IBD. In each subgroup, 5 participants with active disease and 5 in remission will be included (active disease is defined as fecal calprotectin \> 250). In addition, 10 fecal donors will be included as healthy controls.
