Brief summary (registry, in English)
Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), is a idiopathic, chronic and frequently disabling inflammatory disorder of the intestines characterized by a dysregulated mucosal immune response that affect more than a million Americans. This protocol is aimed at obtaining tissue samples to test for expression of genes associated with IBD and to better understand the pathogenesis of IBD with the study of genetics, proteomics, physiologic processes and microbiomes (microbiology).
