The association of de novo anti-HLA-DPB1 donor-specific antibody formation and primary graft failure after allogeneic hematopoietic cell transplantation

Abstract

Despite advances in HLA matching, graft failure remains a serious complication after allogeneic hematopoietic cell transplantation (HCT). Pre-formed anti-HLA donor-specific antibodies (DSAs) have been associated with graft failure, but the impact of newly developing (de novo) anti-HLA antibodies on HCT outcomes remains unknown. Here, we present the first reported case of graft failure associated with de novo anti-HLA-DPB1 DSA after a 10/10 matched unrelated donor HCT. Based on this observation, testing for DSA should be considered in case of unexplained pancytopenia after allogeneic transplantation, especially after reduced intensity conditioning.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

Antibody Specificity

Antibodies produced by B cells are highly specific for antigen as a result of random gene recombination and somatic hypermutation and affinity maturation. As the main effector of the humoral immune system, antibodies can neutralize foreign cells. Find the latest research on antibody specificity here.
