Vedolizumab-induced acute pancreatitis: the first reported clinical case.

Drug-induced acute pancreatitis (DIAP) is a rare, but clinically significant diagnosis. Vedolizumab, an α4β7 integrin inhibitor, which was approved in 2015 for treatment of moderate to severe inflammatory bowel disease, is a well-tolerated medication with a favourable safety profile and minimal serious adverse events in premarketing clinical trials. We present the first reported case of acute pancreatitis directly attributable to vedolizumab. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.
