De novo isolated gastrointestinal tract vasculitis without associated systemic disease in renal transplant recipients successfully treated with rituximab

摘要

Systemic vasculitic diseases can show recurrence after kidney transplantation, but de novo systemic vasculitis is rarely seen after kidney transplantation, and in literature, there are only a few cases. In general population, the incidence of isolated organ vasculitis is unknown, and according to the best of our knowledge, there is no information about de novo isolated organ vasculitis after renal transplantation. We report, most probably, the first case of a 40-year-old woman who was restarted on dialysis treatment after renal transplantation and developed isolated gastrointestinal vasculitis and intestinal hemorrhage under immunosuppressive treatment. She was treated successfully with rituximab.
