Epstein-Barr virus associated colitis in kidney transplant patients: a case series.

Background: Gastrointestinal complications are common in kidney transplant (KT) patients and can be a consequence of the chronic use of immunosuppression. The differential diagnosis of colitis in KT patients includes intolerance to immunosuppressive agents, namely mycophenolate mofetil, inflammatory bowel disease (IBD) and opportunistic infections. Epstein-Barr virus (EBV) infection may cause post-transplant colitis or trigger IBD, although is seldom thought as the causative pathogen.
