Transfusion-associated graft-versus-host disease in a patient with Waldenstrom's macroglobulinaemia.

摘要

BACKGROUND AND OBJECTIVES: Routine irradiation of cellular blood products is not presently recommended for patients with non-Hodgkin's lymphoma (NHL). MATERIALS AND METHODS: We report the case of a 72-year-old-man with Waldenstrom's macroglobulinaemia who developed transfusion-associated graft-versus-host disease (TA-GvHD) 13 days following a non-irradiated red cell transfusion. RESULTS: The patient had not previously received purine analogues and none of the donors was homozygous for a human leucocyte antigen (HLA) haplotype that was shared by the recipient. Therefore, his only apparent risk factor was lymphoplasmacytoid NHL. CONCLUSIONS: This case further strengthens the argument that NHL per se is a risk factor for TA-GvHD and supports the proposal that the guidelines for prophylactic irradiation of cellular blood products be extended to include all cases of NHL.
