Primary Investigator:
Mark Silverberg, MD
Enrolment: Ongoing

The objective is to assess the composition of the microbiome in patients with and without PSC, IBD patients without PSC (Ulcerative colitis and colonic Crohn’s disease) and healthy controls.

This research may lead to a better understanding of why the disease occurs and what role the gut microbiome and other markers play in PSC and/or IBD.

Eligibility: Anyone who has a confirmed diagnosis of Primary Sclerosing Cholangitis and/or IBD (either Crohn's Disease or Ulcerative Colitis). Also, if you do not have IBD (i.e. Crohn's Disease or Ulcerative colitis) and do not have a family history of IBD and are willing to participate as a healthy control, your help would be greatly appreciated.
