Abstract:
Human leukocyte antigen (HLA) mismatch increases the risk of severe graft-versus-host disease (GVHD) and transplant-related mortality. However, the variety of stem cell sources such as cord blood units or the improvements in GVHD prophylaxis makes the interpretation of HLA mismatch more complex. In unrelated transplantation, the locus of HLA mismatch has a great impact on the donor candidate selection, whereas in related transplantation, it has an impact on the intensity of GVHD prophylaxis because donor availability is limited. Anti-thymocyte globulin and post-transplant cyclophosphamide are attractive GVHD prophylactic agents to reduce the risk of immune-associated complications in HLA-mismatched transplantations. HLA mismatch has a reduced impact in adult cord blood transplantation. In this review article, the impact of HLA mismatch based on graft sources is discussed.
