How I treat How I treat EBV lymphoproliferation

Epstein-Barr virus (EBV)–associated Bcell lymphoproliferation is a life-threatening complication after hematopoietic stem cell or solid organ transplantation resulting from outgrowth of EBV-infected B cells that would normally be controlled by EBVcytotoxic T cells. During the past decade, early detection strategies, such as serial measurement of EBV-DNA load in peripheral blood samples, have helped to identify high-risk patients and to diagnose early lymphoproliferation. Treatment options include manipulation of the balance between outgrowing EBV-infected B cells and the EBV cytotoxic T lymphocyte response and targeting the B cells with monoclonal antibodies or chemotherapy. Major challenges remain for defining indications for preemptive therapies and integrating novel and conventional therapies. (Blood. 2009;114:4002-4008)
