Abstract

Recent evidences have shown that several host genetic factors influence susceptibility or protection to hepatitis C virus (HCV) infection. There are controversial data regarding the associations of human leukocyte antigens (HLA) and the clearance or progression of HCV. The aim of this study was to investigate whether particular HLA molecules were associated with HCV infection in recipients awaiting kidney transplantation considered at high-risk to infection due to protracted hemodialysis treatment. To this purpose, 301 kidney recipients with HCV infection and 1103 uninfected recipients were examined for HLA class I and II molecules. In our case-control study, HLA-A(*)26 is positively associated with HCV infection while HLA-A(*)29, -B(*)40 and -DRB1(*)01 are negatively associated with HCV infection. Multiple logistic regression analysis demonstrated that age (OR = 1.02; 95% CI = 1.01-1.04; p < 0.00), HLA-A(*)26, -A(*)29, -B(*)40 and -DRB1(*)01 [(OR = 1.54; 95% CI = 1.03-2.30; p = 0.03); (OR = 0.50; 95% CI = 0.26-0.99; p = 0.05); (OR = 0.42; 95% CI = 0.23-0, 7; p = 0.01); (OR = 0.62; 95% CI = 0.41-0, 94; p = 0.03); respectively] are independent predictors of HCV infection. Our results suggest that particular HLA molecules, as host genetic factors, may have a relationship with susceptibility or protection to HCV infection also in recipients awaiting kidney transplantation.
