ABSTRACT
OBJECTIVE@#To study the association between IL-10 gene-592(C→A) (rs1800872) single nucleotide polymorphism (SNP) and the graft versus host disease (GVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in children.@*METHODS@#Ninety-seven childhood patients and seventy-one donors in the Hematology Oncology Center of Beijing Children's Hospital from Jan 2011 to Jul 2017 were enrolled in this study. The genomic DNA was extracted from peripheral blood cells and the SNP genotype was analyzed using TaqMan SNP genotyping assay.@*RESULTS@#In malignant patients with AA genotype, the incidence of Ⅱ-Ⅳ grade acute GVHD (aGVHD) was lower than that in patients with AC and CC genotype (9.1% vs 43.5%) (P<0.01), and the gastrointestinal aGVHD rate was also lower (9.1% vs 39.1%) (P<0.05). There's no significant association between patients' genotype and Ⅱ-Ⅳ grade aGVHD in total patients and non-malignant patients. Also, the genotype in patients did not corelate with chronic GVHD (cGVHD) and 1 year transplantation-related mortality (TRM). In cases who received HSCT of donors with AA genotype, the liver aGVHD rate was higher than that in cases who received HSCT of donors with AC and CC genotype (23.1% vs 0.0%) (P<0.05), but the genotype in donors did not correlate with Ⅱ-Ⅳ grade aGVHD, cGVHD and 1 year TRM.@*CONCLUSION@#AA genotype in the IL-10 gene-592 (C→A) (rs1800872) single nucleotide polymorphism in patients protects pediatric malignant patients against Ⅱ-Ⅳ grade aGVHD and gastrointestinal aGVHD after allo-HSCT. AA genotype in donors is a risk factor for liver aGVHD after allo-HSCT in non-malignant disease.
