Systematic Literature Review and Meta-Analysis of Renal Function in Human Immunodeficiency Virus (HIV)-Infected Patients Treated with Atazanavir (ATV)-Based Regimens.

ABSTRACT: Some HIV antiretroviral therapies (ART) have been associated with renal toxicities, which become of increasing concern as HIV-infected patients age and develop comorbidities. The objective of this study was to evaluate the relative impact of atazanavir (ATV)-based regimens on the renal function of adult patients with HIV. We conducted a systematic literature review by searching PubMed, EMBASE, Cochrane library, and the CRD from 2000 until March 2013. Major HIV-related conferences occurring in the past two years were also searched. All randomized clinical trials and large cohort studies assessing renal function in treatment-naïve and/or treatment-experienced HIV patients on ATV-based regimens were included. Fixed-effect mixed-treatment network analyses were carried out on the most frequently reported renal outcomes. 23 studies met the inclusion criteria, and change in estimated glomerular filtration rate (eGFR) from baseline to 48 weeks was identified as the main outcome. Two networks including, respectively, six studies (using the Cockcroft-Gault method) and four studies (using MDRD and CKD-EPI) were analysed. With CG network, ATV/r + TDF/FTC was associated with lower impact on the decline of eGFR than ATV/cobicistat + TDF/FTC but with higher decrease in eGFR than ATV/r + ABC/3TC (difference in mean change from baseline in eGFR respectively +3.67 and -3.89). The use of ATV/cobicistat + TDF/FTC led to a similar decline in eGFR as EVG/cobicistat/TDF/FTC. With respect to third agents combined with TDF/FTC, ATV/r had a lower increase in eGFR in comparison to EFV, and no difference was shown when compared to SQV/r and DRV/r. The effect of ATV-based regimens on renal function at 48 weeks appears similar to other ART regimens and appears to be modest regardless of boosting agent or backbone, although TDF containing backbones consistently leads to greater decline in eGFR.

Project description:ObjectivePatients with HIV infection have an increased risk of cardiovascular disease compared with uninfected individuals. Antiretroviral therapy with atazanavir (ATV) delays progression of atherosclerosis markers; whether this reduces cardiovascular disease event risk compared with other antiretroviral regimens is currently unknown.DesignPopulation-based, noninterventional, historical cohort study conducted from 1 July 2003 through 31 December 2015.SettingVeterans Health Administration hospitals and clinics throughout the United States.ParticipantsTreatment-naive patients with HIV infection (N = 9500).Antiretroviral exposuresInitiating antiretroviral regimens containing ATV, other protease inhibitors, nonnucleoside reverse transcriptase inhibitors (NNRTIs), or integrase strand transfer inhibitors (INSTIs).Main outcome/effect size measuresIncidence rates of myocardial infarction (MI), stroke, and all-cause mortality within each regimen. ATV versus other protease inhibitor, NNRTI, or INSTI covariate-adjusted hazard ratios by using Cox proportional hazards models and inverse probability of treatment weighting.ResultsIncidence rates for MI, stroke, and all-cause mortality with ATV-containing regimens (5.2, 10.4, and 16.0 per 1000 patient-years, respectively) were lower than with regimens containing other protease inhibitors (10.2, 21.9, and 23.3 per 1000 patient-years), NNRTIs (7.5, 15.9, and 17.5 per 1000 patient-years), or INSTIs (13.0, 33.1, and 21.5 per 1000 patient-years). After inverse probability of treatment weighting, adjusted hazard ratios (95% confidence intervals) for MI, stroke, and all-cause mortality with ATV-containing regimens versus all non-ATV-containing regimens were 0.59 (0.41-0.84), 0.64 (0.50-0.81), and 0.90 (0.73-1.11), respectively.ConclusionAmong treatment-naive HIV-infected patients in the Veterans Health Administration initiating ATV-containing regimens, risk of both MI and stroke were significantly lower than in those initiating regimens containing other protease inhibitors, NNRTIs, or INSTIs.

Project description:IntroductionPatients with human immunodeficiency virus (HIV) infection have an increased risk of cardiovascular disease (CVD). While viral suppression with antiretroviral therapy decreases CVD risk overall, several studies have suggested that certain antiretrovirals, particularly certain protease inhibitors, may be associated with an increased relative risk of CVD. In AIDS Clinical Trials Group 5260 s, ritonavir-boosted atazanavir (ATV) was associated with slower atherosclerosis progression compared to ritonavir-boosted darunavir and raltegravir, potentially due to hyperbilirubinemia. Although hyperbilirubinemia may lead to increased rates of treatment discontinuation, it may also contribute to a favorable cardiovascular (CV) profile for ATV. To fully elucidate the effect of ATV on CVD risk among HIV-infected patients, a systematic review of the literature was performed.MethodsA systematic search of the PubMed and Embase databases was conducted on August 26, 2015, using terms to identify papers that discuss ATV, HIV, and CVD. Articles were limited to English-language publications of randomized-controlled or observational studies investigating adult humans. The primary outcome was the incidence of CVD. Articles describing surrogate markers of CVD were also included.ResultsTen studies were included in this qualitative analysis: six reported CVD outcomes, two reported data on atherosclerosis as assessed by carotid intima-media thickness (cIMT), and two reported outcomes related to endothelial function. The studies reporting the incidence of myocardial infarction (MI) among HIV-infected patients showed that ATV (boosted and unboosted) was not associated with an increased risk of acute MI. Other CV endpoints were similarly unaffected by treatment with ATV. Compared with non-ATV-based regimens, ATV had beneficial effects on cIMT progression in the publications identified, with no apparent impact on endothelial function.ConclusionsThis analysis showed that there was no increased risk or occurrence of adverse CV events among HIV-infected patients receiving ATV. Markers of atherosclerosis were improved, suggesting a possible antioxidant effect of ATV, and endothelial function was not affected.FundingBristol-Myers Squibb (article processing charges and medical writing support).

Project description:PurposeThe 144-week results of the open-label, multicenter Atazanavir/Ritonavir Induction with Epzicom Study (ARIES) were stratified by gender to compare treatment responses.MethodsA total of 369 HIV-infected, antiretroviral-naïve subjects receiving once-daily abacavir/lamivudine + atazanavir/ritonavir (ATV/r) whose HIV-1 RNA was <50 copies/mL by week 30 were randomized 1:1 at week 36 to maintain or discontinue ritonavir for 108 subsequent weeks. Between- and within-treatment gender-related efficacy and safety differences were analyzed.ResultsSubjects were 85% male; 64% white; and had a mean age of 39 years, baseline median HIV-1 RNA of 114,815 copies/mL, and median CD4+ cell count of 198 cells/mm3. Gender (ATV [n=189]: 29 females/160 males; ATV/r [n=180]: 25 females/155 males) and most other demographics were similar between groups; more females than males were black (65% vs 25%) and fewer females had baseline HIV-1 RNA ≥100,000 copies/mL (41% vs 58%). At week 144, no significant differences between genders were observed in proportion maintaining HIV-1 RNA <50 copies/mL (ATV, 79% vs 77%; ATV/r, 60% vs 75%) or <400 copies/mL (ATV, 83% vs 84%; ATV/r, 68% vs 82%) (intent-to-treat-exposed: time to loss of virologic response analysis); median CD4+ change from baseline (ATV, +365 vs +300 cells/mm3; ATV/r, +344 vs +301 cells/mm3); proportion with treatment-related grade 2-4 adverse events (baseline to week 144: ATV, 41% vs 31%; ATV/r, 36% vs 43%; weeks 36 to 144: ATV, 14% vs 13%; ATV/r, 24% vs 23%); or proportion developing fasting lipid changes. Female and male virologic failure rates (ATV, 0 vs 5; ATV/r, 2 vs 4) and proportions completing the study were similar during the extension phase. Primary withdrawal reasons were loss to follow-up and pregnancy for females and loss to follow-up and other for males.ConclusionOver 144 weeks, no significant gender differences were observed in efficacy, safety, or fasting lipid changes with abacavir/lamivudine +ATV or abacavir/lamivudine +ATV/r.
