[Impacts of donor and recipient's SNP of cytokine and cytokine receptor on early acute renal allograft rejection].

Objective: To investigate the impact of donor and recipient's SNP of cytokine and cytokine receptor on early acute rejection after renal transplantation.

Methods: (1) 129 cases of cadaveric renal allograft recipients were divided into two groups according to the presence or absence of acute graft rejection. The distribution of 21 single nucleotide polymorphisms in cytokines and cytokine receptors gene were compared between two groups as well as latent factors affecting the development of acute rejection. (2) Based on the result of HLA-DR matching between donor and recipient, the recipients with AR were stratified into two conditions, 0-1 locus mismatched (0-1MM) and completely mismatched (2MM). By aids of SPSS 11.5 software, association analysis was assessed using Kruskal Wallis test, 2 x 2 or 2 x n contingency table, the Chi-square test.

Results: (1) Of 129 recipients of renal transplantation, 39 developed acute graft rejection (30.2%). (2) Compared with recipients without acute rejection, the number of HLA-DR mismatching was significantly higher in rejection group. (3) In rejection group and non-rejection group, the gene polymorphism distribution was significantly different. (4) 0-1MM group and 2MM group were various in the gene polymorphism distribution.

Conclusions: In the whole, the susceptibility of acute rejection after renal transplantation may be predicted by the donor and recipient's SNP of cytokine and cytokine receptor.
