Vedolizumab (Entyvio®) for the Treatment of Pyoderma Gangrenosum in a Crohn's Disease Patient.

Vedolizumab is a humanized monoclonal integrin blocker with gut selective effects on lymphocyte trafficking. Its efficacy and safety for the treatment of moderate to severe Crohn's disease and ulcerative colitis were demonstrated by phase III GEMINI studies (GEMINI 1 trial: Vedolizumab as Induction and Maintenance Therapy for Ulcerative Colitis; GEMINI 2 trial: Vedolizumab as Induction and Maintenance Therapy for Crohn's Disease). Post hoc analyses of the GEMINI studies further showed the potential benefit of vedolizumab for treating various extraintestinal manifestations, including arthralgias, pyoderma gangrenosum, erythema nodosum, and uveitis. However, findings lacked statistical significance highlighting the need for more clinical data describing vedolizumab's effects on extraintestinal manifestations. There are currently few case reports describing the effect of vedolizumab on pyoderma gangrenosum specifically. We report a Crohn's disease patient whose severe pyoderma gangrenosum of her legs, abdomen, and face have been inactive since starting vedolizumab.
