Abstract
During the early mid-1990s, a number of rural farmers across central China were employed to the unregulated plasmaselling-activity and many of them were infected by HIV-1. However, AIDS progression in the former blood donors (FBDs) is various. The aim of this study is to assess human leukocyte antigen (HLA) class I allele distribution in FBDs and evaluate its association with HIV-1 infection and disease progression. A total of 353 FBDs were enrolled in the cohort including 294 ART naïve HIV-1 seropositive and 59 HIV-1 seronegative age-matched subjects. The viral load and CD4/CD8 T cell counts were assessed in all subjects. Compared with HIV-seropositive group, the frequency of HLA-A*03 in control was significantly higher. After classifying the HLA-B alleles of the subjects according to the presence of Bw4/Bw6 serological epitopes, detrimental effect of HLA Bw6/ Bw6 homozygosity was also confirmed in the HIV-seropositive subjects. This study provides novel evidence on HLA class I allele distribution and association of HLA-A*03 frequency with HIV-1 infection and viremia in the HIV-1 infected FBDs, which may throw light on intervention strategy for the HIV-1 infection and our understanding how host immunity and genetic background affect HIV infection and AIDS progression.
