Rapid development of an immunoblastic lymphoma and death in children following cadaveric renal transplantation.

We report on three children who underwent cadaveric renal transplantation and subsequently developed an immunoblastic lymphoma, leading to death in two patients. The development of the lymphoma occurred following a multi-drug immunosuppression regimen ending with monoclonal antilymphocyte (OKT3) treatment for biopsy-proven cellular and vascular acute rejection. These patients represent three of 11 children who received OKT3 treatment for rejection in the last 18 months at this institution. Following the diagnosis of lymphoma, all three patients were treated by transplant nephrectomy, cessation of immunosuppression, and administration of intravenous acyclovir. The first two patients died at 4 days and 4 weeks, respectively, after the definitive diagnosis was made with widespread metastatic disease. The remaining child is a short-term survivor (13 months), free of demonstrable malignancy. Multidrug regimens for immunosuppression have a profound effects on T cell function. These effects, when combined with a primary infection by the Epstein-Barr virus, are implicated in the rapid development of the lymphomas and are responsible for the death of these two children.
