Limits of HLA mismatching in unrelated hematopoietic cell transplantation.
HLA matching between the donor and recipient improves the success of unrelated hematopoietic cell transplantation (HCT). Matched donors are available for only a minority of patients. Further information is needed to evaluate the limits of HLA mismatching. We examined the association of mortality with HLA-A, -B, -C, -DRB1, and -DQB1 mismatching in 948 patients who received a T-replete unrelated ...
متن کاملThe impact of HLA unidirectional mismatches on the outcome of myeloablative hematopoietic stem cell transplantation with unrelated donors.
The impact of HLA homozygosity at mismatched (MM) loci on the outcome of 2687 myeloablative unrelated donor hematopoietic cell transplantations performed for malignant disease was evaluated among 4 groups: 7/8 bidirectional MM transplants (donor and recipient heterozygous MM, n = 1393), 7/8 host-versus-graft (HVG) vector MM (recipient homozygous, n = 112), 7/8 graft-versus-host (GVH) vector MM ...
متن کاملHLA-C Incompatibilities in Allogeneic Unrelated Hematopoietic Stem Cell Transplantation
An increasingly larger fraction of patients with hematological diseases are treated by hematopoietic stem cells transplantation (HSCT) from HLA matched unrelated donors. Polymorphisms of HLA genes represent a major barrier to HSCT because HLA-A, -B, -C and DRB1 incompatibilities confer a higher risk of acute graft-versus-host disease (aGVHD) and mortality. Although >22 million volunteer HLA-typ...
متن کاملFrequent HLA class I and DP sequence mismatches in serologically (HLA-A, HLA-B, HLA-DR) and molecularly (HLA-DRB1, HLA-DQA1, HLA-DQB1) HLA-identical unrelated bone marrow transplant pairs.
The rates of graft-versus-host disease (GVHD) and rejection are significantly higher among recipients of unrelated donor marrow (BM) than in recipients of marrow from HLA-identical siblings, even when donors and recipients are mixed lymphocyte culture (MLC) compatible and serologically and Dw identical. It has been hypothesized that phenotypically silent HLA class I and DP sequence mismatches m...
متن کاملThe Association Between Broad Antigen HLA Mismatches, Eplet HLA Mismatches and Acute Rejection After Kidney Transplantation
BACKGROUND Epitope matching, which evaluates mismatched amino acids within antigen-antibody interaction sites (eplets), may better predict acute rejection than broad antigen matching alone. We aimed to determine the association between eplet mismatches and acute rejection in kidney transplant recipients. METHODS The association between eplet mismatches, broad antigen mismatches and acute reje...
