|Abstract:||<h4>Background</h4>Existing data indicate that non-human leukocyte antigen (HLA) immunogenetic polymorphisms influence the risk of complications after allogeneic hemopoietic stem-cell transplantation. However, prior studies have been limited by small sample size and limited genotyping.<h4>Methods</h4>We examined 22 polymorphisms in 11 immunoregulatory genes including cytokines, mediators of apoptosis, and host-defense molecules by polymerase chain reaction using sequence-specific primers in 160 related myeloablative transplants. Associations were confirmed in two independent cohorts.<h4>Results</h4>An intronic polymorphism in the tumor necrosis factor gene (TNF 488A) was associated with the risk of acute graft-versus-host disease (GVHD) (odds ratio [OR] 16.9), grades II to IV acute GVHD (OR 3.3), chronic GVHD (OR 12.5), and early death posttransplant (OR 3.4). Recipient Fas -670G and donor interleukin (IL)-6 -174G were independent risk factors for acute GVHD. Recipient IL-10 ATA and Fas -670 genotype were independent risk factors for chronic GVHD. Recipient IL-1beta +3953T was associated with hepatic acute GVHD, and Fas -670G was associated with major infection.<h4>Conclusions</h4>These results highlight the potential importance of cytokine and apoptosis gene polymorphisms in stem-cell transplantation, and indicate that non-HLA genotyping may be useful to identify individuals at the highest risk of complications and new targets for therapeutic intervention.|
