  • Title: Donor-specific transfusions. Donor-recipient HLA compatibility, recipient HLA haplotype, and antibody production.
    Author: Radvany RM, Patel KM.
    Journal: Transfusion; 1988; 28(2):137-41. PubMed ID: 3281335.
    Abstract:
    HLA profiles of 25 donor-specific transfusion (DST) kidney donor-recipient pairs were analyzed for HLA antigen compatibility. Serum samples collected during and after DST were tested for cytotoxic antibodies against T and B lymphocytes of the donors and 30 normal individuals. Eleven recipients did not produce cytotoxic antibodies to the antigens of their DST donors, and eight produced cold and/or warm, broadly reactive B-cell antibodies. Six patients (24%) produced HLA-A, B, C, and/or DR antibodies. Three of these individuals produced antibodies after two immunizations, while others required three immunizations. Three of the 11 antibody nonproducers (17%) had not received previous transfusions, as compared to three of the eight antibody producers (43%). Comparison of HLA profiles revealed 22 percent of the HLA-A, B, DR identities between the transfusion donor and recipient in antibody nonproducers as compared to 9 percent of the HLA-A, B, DR identities in antibody producers. The HLA-A2, B40, DR4 haplotype and HLA-DRW6 antigen were more common among antibody producers than among nonproducers, who had an excess of the HLA-B8, DR3 haplotype. These results are consistent with the hypothesis that there may be high- and low-responder HLA haplotypes that control immunologic responsiveness to histocompatibility antigens.
