Posttransplantation lymphoproliferative disorders in pediatric thoracic organ recipients

Abstract

Objective: To determine the frequency, predisposing factors, clinical presentation, and outcome of posttransplantation lymphoproliferative disorders (PTLDs) in pediatric thoracic organ transplant recipients. Methods: Retrospective review of the medical records of all 120 children who survived longer than 1 month after thoracic organ transplantation at our center. Results: PTLD was diagnosed in 14 patients (11.7%), including 7.7% of heart and 19.5% of heart-lung/lung recipients. Presentation of PTLD was variable, ranging from asymptomatic lung nodules on chest radiograph to diffuse multiorgan failure. Treatment with a reduction of immunosuppression and antiviral therapy resulted in resolution..
