A case of transfusion‐associated graft‐versus‐host disease not prevented by white cell‐reduction filters

Abstract

A case of transfusion-associated graft-versus-host disease (TA-GVHD) in a patient with non-Hodgkin's lymphoma is reported. The patient, a 67-year-old woman, was diagnosed as having diffuse, mixed type non-Hodgkin's lymphoma, at clinical stage IIIA. She was treated with combination chemotherapy and received multiple blood transfusions for anemia and thrombocytopenia. Although white cells (WBCs) were reduced in the transfused components by WBC-reduction filters, the patient developed TA-GVHD that was confirmed by skin biopsy. It is suggested that the WBC reduction attained with these filters does not prevent TA-GVHD in immunocompromised patients. It is recommended that all blood components should be irradiated before transfusion to such patients.
