Impact of Human Leukocyte Antigen Loci and Haplotypes on Intestinal Acute Graft-versus-host Disease after Human Leukocyte Antigen-matched Sibling Peripheral Blood Stem Cell Transplantation.

Background: Acute graft-versus-host disease (aGVHD) is a common and severe complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT). Some studies have found that the presence of certain specific human leukocyte antigen (HLA) loci could affect the occurrence of aGVHD. Meanwhile, the impact of HLA haplotypes on aGVHD has been rarely studied.

Acute graft-versus-host disease (aGVHD) is associated with an immune dysregulation usually mediated by T lymphocytes. Recently, IL-17-producing T cells including Th17 and Tc17 cells have been implicated in immune-related diseases. However, their roles in aGVHD remain uncertain.

Objective: To investigate the risk factors of intestinal acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).

Methods: The clinical data of 534 cases of 533 patients undergoing allo-HSCT during Jan 2004 and Sep 2012 were retrospectively analyzed. The effects of donor-recipient HLA mismatching, recipient age, donor age, donor-recipient sex combination, donor-recipient relationship, HSC source, conditioning regimen with or without total body irradiation (TBI) and HLA loci on intestinal aGVHD with different severity were analyzed by Logistic regression.
