title: Diagnosis of transfusion-associated graft-versus-host disease by genetic fingerprinting and polymerase chain reaction.
abstract: A patient with Hodgkin's disease (clinical stage IIIB) received chemotherapy and total nodal irradiation. After the transfusion of filtered packed red cells, this patient developed transfusion-associated graft-versus-host disease (TA-GVHD). The genetic fingerprint of the patient's peripheral blood lymphocytes (PBLs) differed completely from that of her other body tissues. Normally, after transfusion, only the patient's own genetic fingerprints are observed in the PBLs, as exemplified in more than 10 control cases in which the transfused blood had not been filtered before transfusion. No signal bands corresponding to those of the blood donor could be demonstrated in samples of the patient's tissue DNA. Moreover, chimerism was detected in the hybridization pattern of the patient's PBLs on the ninth day after the onset of symptoms. Polymorphic simple repeats in the HLA-DRB gene after amplification by polymerase chain reaction were also investigated, which confirmed the fingerprinting results. The advantages of these methods for the diagnosis of TA-GVHD include the rapid and unequivocal diagnosis as well as the fact that there is no need for the relatives to be HLA typed.
