    Abstract

    Background: Studies relating certain chemokine and chemokine receptor gene alleles with the outcome of HIV-1 infection have yielded inconsistent results. Objective: To examine postulated associations of genetic alleles with HIV-1 disease progression. Design: Meta-analysis of individual-patient data. Setting: 19 prospective cohort studies and case-control studies from the United States, Europe, and Australia. Patients: Patients with HIV-1 infection who were of European or African descent. Measurements: Time to AIDS, death, and death after AIDS and HIV-1 RNA level at study entry or soon after seroconversion. Data were combined with fixed-effects and random-effects models. Results: Both the CCR5-Δ32 and CCR2-64I alleles were associated with a decreased risk for progression to AIDS (relative hazard among seroconverters, 0.74 and 0.76, respectively; P = 0.01 for both), a decreased risk for death (relative hazard among seroconverters, 0.64 and 0.74; P < 0.05 for both), and lower HIV-1 RNA levels after seroconversion (difference, -0.18 log10 copies/mL and -0.14 log10 copies/mL; P < 0.05 for both). Having the CCR5-Δ32 or CCR2-64I allele had no clear protective effect on the risk for death after development of AIDS. The results were consistent between seroconverters and seroprevalent patients. In contrast, SDF-1 3′A homozygotes showed no decreased risk for AIDS (relative hazard for seroconverters and seroprevalent patients, 0.99 and 1.03, respectively), death (relative hazard, 0.97 and 1.00), or death after development of AIDS (relative hazard, 0.81 and 0.97; P < 0.5 for all). Conclusions: The CCR5-Δ32 and CCR2-64I alleles had a strong protective effect on progression of HIV-1 infection, but SDF-1 3′A homozygosity carried no such protection.
