In inflammatory bowel disease refractory to established therapies, treatment with biological agents such as monoclonal tumor necrosis factor-α antibodies is an established therapeutic option. However, application in renal allograft recipients is either not licensed or has not yet been systematically examined. Herein, we present 2 case reports of renal allograft recipients who had steroid-refractory ulcerative colitis who demonstrated improvement of symptoms after treatment with infliximab, without signs of effect on transplant function. In both patients, stool frequency decreased significantly. Colonoscopy controls and histologic examination after initiation of treatment revealed a state of remission. Renal function parameters and drug concentrations remained constant.
