title: [Analyses of risk factors for intestinal acute graft-versus-host disease after allogeneic hematopoietic stem cell transplantation].
abstract: 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.
  
  
  RESULTS
  Intestinal aGVHD occurred in 123(23.0%) cases, with 86(16.1%) cases of stage 1 intestinal aGVHD(16.1%) and 37(6.9%) cases of stage 2 to 4 intestinal aGVHD. Multivariate analysis showed that donor-recipient HLA mismatching (OR=2.519, P=0.002), increasing donor age (OR=1.034, P=0.003), female donor for male recipient (OR=1.855, P=0.007) were risk factors for intestinal aGVHD, HLA-B38 (OR=0.256, P=0.032) was its protective factor. Donor-recipient HLA mismatching (OR=2.799, P=0.011), increasing donor age (OR=1.045, P=0.012), HLA-A1 (OR=4.157, P=0.002), A30 (OR=3.143, P=0.005) were risk factors for stage 2 to 4 intestinal aGVHD.
  
  
  CONCLUSIONS
  Occurrence of intestinal aGVHD and its severity are associated with donor-recipient HLA mismatching, donor age, donor-recipient sex relationships and some HLA loci.
