Abstract

Administration of ipilimumab, a cytotoxic T-lymphocyte associated antigen-4-blocking monoclonal antibody, leads to enhancement of the anti-tumor T-cell response and as a result shows a significant survival benefit in metastatic melanoma patients. Therefore patients are currently receiving this promising therapy as a second-line strategy. Unfortunately, by activation of the T-cell immune respons, ipilimumab therapy may lead to an unwanted induction of different autoimmune phenomena. Diarrhoea and colitis occur in up to one third of patients. Here we present a case of ipilimumab induced ileocolitis which was successfully treated with infliximab, an anti-tumor necrosis factor monoclonal antibody, after corticosteroid therapy failure. Although formal trials are lacking, recently publicated series suggest that infusional therapy of infliximab is effective in ipilimumab induced ileocolitis.

Core tip: This paper presents a case of ipilimumab induced ileocolitis which was successfully treated with infliximab, an anti-tumor necrosis factor monoclonal antibody, after corticosteroid therapy failure. Although formal trials are lacking, recently publicated series suggest that infusional therapy of infliximab is effective in ipilimumab induced ileocolitis.
