Abstract

Anti-CD20-based chemo-immunotherapeutic regimens have been suggested to assist in the management of Epstein-Barr virus (EBV)-induced hemophagocytic lymphohistiocytosis (HLH) and EBV-associated post-transplant lymphoproliferative disorders (EBV-PTLD), by reducing EBV viral load and EBV-induced inflammation. Herein we report a fatal EBV-related HLH in the context of Hodgkin lymphoma (HL)-like Richter's transformation of B chronic lymphocytic leukemia (B-CLL), two months after rituximab treatment. The complex balance between EBV driven T-cell stimulation and immunosuppressive therapy in the context of multiple immune deficits is discussed.

Keywords: Anti-CD 20; EBV; Epstein barr virus; Hemophagocytic lymphohistiocytosis; Hodgkin lymphoma; Richter’s; Rituximab.
