Abstract

Hematopoietic effects of human Herpesvirus-6 (HHV-6) infection following bone marrow transplantation (BMT) include delayed engraftment and early myelosuppression. Variant A has not been isolated after BMT. A case of graft failure is reported following an HLA-identical BMT for chronic myelogenous leukemia (CML) in chronic phase. Evaluation of bone marrow during the period of graft failure revealed variants A and B of HHV-6 by culture, immunofluorescence, polymerase chain reaction (PCR), and immunohistochemistry. Evidence for other cases of graft failure, including cytomegalovirus (CMV), could not be found. A hypothesis is proposed that late graft failure in this case was due to variant A of HHV-6.
