Antibody-mediated rejection (AMR) is the leading cause of graft failure after kidney transplantation. C-C Chemokine receptor 5 (CCR5) plays an important role in immune cell migration and cytokine release. The CCR5 deficient mice have been implicated in experimental model for AMR. The aim of this study is to investigate the influence of genetic variation of CCR5 in susceptibility to AMR after kidney transplantation
We analyzed 190 recipients who underwent kidney transplantation without pre-transplant donor specific antibodies between May 2013 and December 2014. We investigated a CCR5 promoter polymorphism, -2459 A>G (rs1799987), that has been shown to affect expression of the CCR5 receptor. Genetic polymorphism was detected by the TaqMan assay.
AMR occurred in 20 patients (10.5%) of 190 kidney transplant recipients within 1 year. The incidences of AMR for AA genotype, AG genotype, and GG genotype were 25% (11/44), 7.1% (7/98), and 4.2% (2/48), respectively (p=0.001). The recipient AA genotype of CCR5 -2459 A>G (rs1799987) was associated with increased risk for AMR after adjusting for covariates such as ABO incompatibility, human leukocyte antigen mismatch, and panel reactive antibodies (OR, 7.123; 95% CI, 1.411-35.967; p=0.017).
The CCR5 -2459 (rs1799987) AA genotype of recipient was an independent risk factor for AMR after kidney transplantation.
