We prospectively studied long-term antiretroviral adherence patterns and their impact on biologic outcomes for human immunodeficiency virus (HIV)-infected participants in 2 randomized, multicenter clinical trials. For the period from baseline to month 12 of the study, participants who reported adherence levels of 100%, 80%-99%, and 0%-79% had plasma HIV RNA levels that decreased by 2.77, 2.33, and 0.67 log(10) copies/mL, respectively (P<.001), whereas their CD4 counts increased by 179, 159, and 53 cells/mm(3), respectively (P<.001). Adherence predicted nondetectable HIV RNA levels (<50 copies/mL) at 12 months of follow-up (P<.001). The HIV RNA level was nondetectable in 72% of participants who reported 100% adherence at all 4 follow-up visits, compared with 66%, 41%, 35%, and 13% of participants who reported 100% adherence at 3, 2, 1, or 0 follow-up visits, respectively (P<.001). Nonwhite race was associated with poorer adherence (P<.001), and older age was associated with better adherence (P<.001).

In patients failing triple drug therapy, GART with expert advice was superior to no-GART as measured by short-term viral load responses.

BackgroundBlack men who have sex with men (MSM) in the United States (US) are affected by HIV at disproportionate rates compared to MSM of other race/ethnicities. Current HIV incidence estimates in this group are needed to appropriately target prevention efforts.MethodsFrom July 2009 to October 2010, Black MSM reporting unprotected anal intercourse with a man in the past six months were enrolled and followed for one year in six US cities for a feasibility study of a multi-component intervention to reduce HIV infection. HIV incidence based on HIV seroconversion was calculated as number of events/100 person-years. Multivariate proportional hazards modeling with time-dependent covariates was used to identify correlates of HIV acquisition.ResultsOf 1,553 Black MSM enrolled, 1,164 were HIV-uninfected at baseline and included in follow-up. Overall annual HIV incidence was 3.0% (95% confidence interval (CI): 2.0, 4.4%) and 5.9% among men ≤30 years old (95% CI: 3.6, 9.1%). Men ≤30 years old reported significantly higher levels of sexual risk and were more likely to have a sexually transmitted infection diagnosed during follow-up. Younger men also were more likely to not have a usual place for health care, not have visited a health care provider recently, and to have unmet health care needs. In multivariate analysis, age ≤30 years (hazard ratio (HR): 3.4; 95% CI: 1.4, 8.3) and unprotected receptive anal intercourse with HIV-positive or unknown status partners (HR: 4.1; 95% CI: 1.9, 9.1) were significantly associated with HIV acquisition.ConclusionIn the largest cohort of prospectively-followed Black MSM in the US, HIV incidence was high, particularly among young men. Targeted, tailored and culturally appropriate HIV prevention strategies incorporating behavioral, social and biomedical based interventions are urgently needed to lower these rates.

This study assesses changes in quality of life (QoL) over time among HIV-infected individuals receiving antiretroviral therapy (ART) and evaluates how this relates to ARTadherence. Prospective, longitudinal data were examined from 1050 participants in two large, randomized, multi-centre antiretroviral clinical trials. QoL was assessed by the SF-12; adherence by the Terry Beirn Community Programs for Clinical Research on AIDS Antiretroviral Medication Self-report. Participants included 20% women, 53% African Americans, 16% Latinos; mean age was 39 years; mean baseline CD4+ cell count 230 cells/mm3; 89% were ART-naïve at entry. Baseline physical and mental health summary QoL scores were 45.4 and 42.9, comparable to scores reported in other advanced HIV populations. Significant improvements in mean QoL scores were seen for the group as a whole after 1 to 4 months on new ART regimens, and persisted for 12 months. Participants reporting 100% ART adherence achieved significantly higher QoL scores at 12 months compared to those with poorer adherence, particularly if 100% adherence was consistent (p < 0.001). Those with at least 80% ART adherence had smaller gains in QoL at 12 months when compared to baseline, while those with < 80% adherence had worsening of QoL. In this analysis, ART adherence was associated with improved QoL, particularly if adherence was sustained.
