Abstract

We have previously shown that the interleukin 10 (IL-10)/-592*A allele of the recipient is associated with less severe acute graft-versus-host disease (GVHD) and a lower risk of nonrelapse mortality after hematopoietic cell transplantation (HCT) from an HLA-identical sibling. In the present study, we examined variation in the IL-10 receptor β gene as a further test of the hypothesis that the IL-10 pathway regulates the risk of acute GVHD. A single nucleotide polymorphism (A/G) at cDNA position 238 of the IL-10 receptor β gene (IL10RB/c238) was genotyped in 953 HC transplant recipients and their HLA-identical sibling donors. IL-10/-592 and IL10RB/c238 genotypes were tested for association with GVHD by multivariable analysis. The IL-10/-592*A allele of the recipient and IL10RB/c238*G allele of the donor were significantly associated with a lower risk of grades III-IV acute GVHD (trend P < .001 and P = .02, respectively). The donor IL10RB/c238*G allele provided protection among patients with the IL-10/-592 A/C or A/A genotypes but not among patients with the high-risk IL-10/-592 C/C genotype. These data suggest an interaction of the patient IL-10/-592 and donor IL10RB/c238 genotypes on risk of GVHD, further supporting the hypothesis that the IL-10 pathway plays an important role in controlling the severity of acute GVHD.
