Abstract:
Objective To evaluate the actual mismatch risk for KIR genes,KIR ligand HLA-C gene and KIR ligand HLA-Bw4I80 related genes in kidney transplant recipients and their donors.Method KIR genes,KIR ligand HLA-C gene and KIR ligand HLA-Bw4I80 related genes were analyzed in 322 recipients and their donors who received kidney transplantation.The effect of mismatches on acute rejection after transplantation was studied as well.Result In 322 cases of recipients and their donors,average mismatch risk for KIR-L gene was 4.73％,9.10％ for KIR-S gene and 1.95％ for KIR ligand HLA-C gene respectively.There were 245 cases (76.09％) of KIR ligand HLA-Bw4I80 related genes mismatch and 77 cases (23.91 ％) of match resepctively.There was no statistically significant difference in AR rate between KIR ligand HLA-Bw4I80 related genes mismatch group and match group (8.16％ in 245 vs.7.79％ in 77) (P＞0.05).AR reversal rate in mismatch group and match group was 95.0％ and 66.7％ (P＞0.05).Conclusion The mismatch risk for KIR ligand HLA-Bw4I80 related genes was even common between kidney transplant recipients and their donors,and this specific mismatch may be of benefit to patients who undergo actuate rejection.Further study is still required.
