title: Rapid response to rituximab in a pediatric liver transplant recipient with post-transplant lymphoproliferative disease and maintenance with sirolimus monotherapy.
abstract: A 12-yr-old girl with end-stage renal disease secondary to primary hyperoxaluria type I received a living related (left lateral segment) liver transplant from her brother as the first step of a staged liver and kidney transplant. Renal transplantation was planned for a later date from the same donor. Nine weeks after transplantation she developed polymorphic PTLD of the tonsils and adenoids. Initial treatment with surgical resection and withdrawal of immunosuppression was insufficient as she developed recurrence of the PTLD lesion 1 wk after surgical resection and reduction of immunsuppression. Treatment with the chimeric monoclonal anti CD20 antibody, rituximab (Mabthera, Hoffman-La Roche AG, Grenzach-Whylen, Germany), resulted in quick response and complete recovery from PTLD within 2 wk, with no recurrence up to 8 months after treatment. Rejection prophylaxis was successfully achieved with Sirolimus (Rapamune, Wyeth Pharmaceuticals Inc., Philadelphia, PA, USA) monotherapy, with no episodes of acute rejection.
