Abstract
Two patients, one with Hodgkin's disease and one with peripheral T cell lymphoma, developed transfusion-associated graft-versus-host disease 16 and 8 days after transfusion of red cell and platelet concentrates. Fever and skin rash were followed rapidly by an elevation of liver enzymes and the onset of diarrhoea and pancytopenia. Despite treatment with high-dose methylprednisolone and anti-lymphocyte globulin, commenced within 7 and 2 days of the onset of rash, grade IV GvHD persisted and both patients died with severe pancytopenia. HLA types of peripheral lymphocytes of the patient with Hodgkin's disease were inconsistent with those of her parents and siblings, but HLA typing of her fibroblasts revealed that her true type was consistent with those of her parents and that her circulating lymphocytes were not genetically her own. The HLA types of the patient with T-cell lymphoma were inconsistent with those of her siblings which suggests, but, in the absence of other evidence, does not prove, chimaerism.
