We examined associations between maternal HLA and vertical HIV-1 transmission in a perinatal cohort of 277 HIV-infected women in Nairobi. HLA class I genes were amplified using sequence-specific oligonucleotide probes and analyses were performed using logistic regression. Maternal A*2301 was associated with increased transmission risk before and after adjusting for maternal viral load (odds ratio [OR]=3.21; 95% CI: 1.42, 7.27, p=0.005, pcorr=0.04; adjusted OR=3.07; 95% CI: 1.26, 7.51, p=0.01, pcorr=NS). That maternal HLA-A*2301 was associated with transmission independent of plasma HIV-1 RNA levels, suggests that HLA may alter infectivity through mechanisms other than influencing HIV-1 viral load.
