Study Summary

Inflammatory bowel disease (IBD), consisting of two major forms, Crohn's disease (CD) and ulcerative colitis (UC), affects more than 1.6 million people in the United States alone. Though the precise mechanisms underlying the inflammation and immune responses in IBD are still being investigated, various inflammatory mediators, including pro-inflammatory cytokines, and genes have been implicated in the disease process. At present, there are no reliable mechanisms to predict response to individual IBD medications. The investigators seek to evaluate whether inflammatory cytokines change longitudinally during treatment with anti-cytokine agents in both treatment primary responders and primary non-responders. In addition, the investigators will be evaluating the pharmacogenetics of treatment response to these agents.

Primary Outcome

The investigators will classify Crohn's disease subjects as primary responders or primary non-responders to anti-TNF-α, ustekinumab, or vedolizumab therapy based on clinical, endoscopic, and/or histologic data. The investigators will compare serum and tissue cytokines in CD subjects at before and after treatment initiation.
