Host genetic influences on highly active antiretroviral therapy efficacy and AIDS-free survival.

ABSTRACT: We studied the influence of AIDS restriction genes (ARGs) CCR5-Delta32, CCR2-64I, SDF1-3'A, IL10-5'A, CX3CR1-V249I, CX3CR1-T280M, and MDR1-C3435T and haplotypes of the CCR5 P1 promoter and RANTES variants -403A, In1.1C, 3'222C, and -28G among HIV-1 infected patients on highly active antiretroviral therapy (HAART) in the Multicenter AIDS Cohort Study (MACS) and the Multicenter Hemophilia Cohort Study (MHCS). Our results indicate that several ARGs also influence therapy efficacy (ie, the success in viral suppression) and subsequent progression to AIDS while on HAART. CCR5-Delta32 decreased time to viral suppression (<200 HIV RNA copies/mL, relative hazard [RH]=1.40; P=0.008) and was protective against AIDS (RH=0.11; P=or<0.0001), whereas the CCR5 P1 haplotype was associated with delayed viral suppression (RNA<50 copies/mL, odds ratio [OR]=0.65; P=0.03) and accelerated time to AIDS (RH=2.68; P=0.02). SDF1-3'A reduced viral suppression (OR=0.61; P=0.02) and accelerated AIDS (RH=3.18; P=0.009). Accelerated AIDS progression was also observed with the RANTES haplotype carrying RANTES-IN1.1C and RANTES-3'222C (P=0.005 to 0.007). In contrast, the RANTES haplotype H1, which lacks suspected deleterious single-nucleotide polymorphisms, was protective against AIDS. CX3CR1-V249I seemed to accelerate viral suppression (RNA<50 copies/mL, OR=1.27; P=0.01). ARG influence after HAART suggests residual HIV-1 replication, and spread continues even in patients successfully suppressing detectable viral RNA.

Project description:PurposeTo describe the outcomes of different treatment approaches for cytomegalovirus (CMV) retinitis in the era of highly active antiretroviral therapy (HAART).DesignProspective cohort study, the Longitudinal Study of the Ocular Complications of AIDS.ParticipantsA total of 250 patients with CMV retinitis and a CD4+ T-cell count <100 cells/μl (n = 221) at enrollment or incident retinitis (n = 29) during cohort follow-up.MethodsThe effects of systemic therapy (vs. intraocular therapy only) on systemic outcomes and the effect of intraocular therapies (ganciclovir implants, intravitreal injections) on ocular outcomes were evaluated.Main outcome measuresMortality, CMV dissemination, retinitis progression, and treatment side effects.ResultsRegimens containing systemic anti-CMV therapy were associated with a 50% reduction in mortality (adjusted hazard ratio [HR], 0.5; 95% confidence interval [CI], 0.3-0.7; P = 0.006), a 90% reduction in new visceral CMV disease (adjusted HR, 0.1; 95% CI, 0.04-0.4; P = 0.004), and among those with unilateral CMV retinitis at presentation, an 80% reduction in second eye disease (adjusted HR, 0.2; 95% CI, 0.1-0.5; P = 0.0005) when compared with those using only intraocular therapy (implants or injections). Compared with systemic treatment only, regimens containing intravitreal injections had greater rates of retinitis progression (adjusted HR, 3.4; P = 0.004) and greater visual field loss (for loss of one half of the normal field, adjusted HR, 5.5; P < 0.01). Intravitreal implants were not significantly better than systemic therapy (adjusted HR for progression, 0.5; P = 0.26; adjusted HR for loss of one half of the visual field, 0.5; P = 0.45), but the sample size was small. Hematologic and renal side effect rates were similar between those groups with and without systemic anti-CMV therapy. The rate of endophthalmitis was 0.017 per eye-year (EY) (95% CI, 0.006-0.05) among those treated with intravitreal injections and 0.01 per EY (95% CI, 0.002-0.04) among those treated with an implant.ConclusionsIn the HAART era, systemic anti-CMV therapy, while there is immune compromise, seems to provide benefits in terms of longer survival and decreased CMV dissemination.Financial disclosure(s)Proprietary or commercial disclosure may be found after the references.
