The detection of anti-HLA antibodies using the Luminex assay is a frequent event in allogeneic hematopoietic stem cell transplantation donors.
We analyzed the impact of anti-HLA antibodies detected in voluntary unrelated donors on the occurrence of graft-versus-host disease (GVHD).
The cumulative incidence of chronic GVHD was significantly enhanced in recipients of grafts from anti-HLA–immunized donors.
