Effects of 96 Weeks of Rosuvastatin on Bone, Muscle, and Fat in HIV-Infected Adults on Effective Antiretroviral Therapy.

ABSTRACT: Heightened inflammation and immune activation are associated with lower bone mineral density (BMD) and lean body mass (LBM) among HIV-infected persons. We hypothesized that a reduction in inflammation with rosuvastatin would be associated with improvements in BMD and LBM. HIV-infected participants on stable antiretroviral therapy without statin indication and with heightened immune activation (?19% CD8(+)CD38(+)HLA-DR(+) T cells) or inflammation (hsCRP ?2 mg/liter) were randomized to rosuvastatin 10 mg daily or placebo for 96 weeks. Among 72 participants randomized to rosuvastatin and 75 to placebo, there were no significant differences in the relative changes in BMD (p > 0.29) or in fat (p ? 0.19). A trend toward increased LBM (p = 0.059) was seen in the rosuvastatin arm without differences in creatinine kinase or self-reported physical activity (p ? 0.10). In a multivariable regression model, rosuvastatin was associated with a significant positive effect on LBM after adjusting for age, sex, race, smoking status, and detectable HIV-1 viral load. Higher baseline sCD163 correlated with increases in LBM from weeks 0 to 96 (p = 0.023); greater changes in total and leg lean mass were seen among statin users with higher compared to lower baseline IP-10 levels (LBM 1.8 vs. -0.3%; p = 0.028 and leg lean mass 2.9 vs. -1.7%; p = 0.012). Rosuvastatin is associated with an absence of toxicity on BMD and a potential benefit on LBM over 96 weeks of therapy. The preservation of LBM in the rosuvastatin arm over the 2 years of the study is of major clinical relevance in delaying loss of muscle mass with aging.

Project description:BackgroundCoenzyme Q10 (CoQ10) deficiency has been associated with statin-induced myopathy, and supplementation with CoQ10 may reduce inflammation markers. The effects of statins on CoQ10 and its anti-inflammatory properties have not been investigated in HIV-positive patients.ObjectiveThe objectives of this study were to examine the effect of rosuvastatin on CoQ10 and CoQ10/LDL ratio over 24-week SATURN-HIV trial, explore the associations between CoQ10 levels and markers of vascular disease, inflammation, and immune activation, and assess whether changes in CoQ10 affected the anti-inflammatory effects of statin therapy or were associated with myalgia symptoms.MethodsThis was a secondary analysis of the SATURN-HIV trial, a 96-week randomized clinical trial of 10 mg daily rosuvastatin vs. placebo in HIV-infected patients on antiretroviral therapy. We assessed the statin treatment effect on CoQ10 levels and CoQ10/LDL ratios and whether changes in these markers were related to myalgias. Relationships between CoQ10, subclinical vascular disease, and biomarkers of inflammation and immune activation were explored using Spearman correlations and multivariable regression models.ResultsOverall, 147 patients were included. Median age was 46 years; 78% were male and 68% African American. At baseline, CoQ10 levels and CoQ10/LDL ratio were modestly correlated with markers of HIV disease, immune activation, and carotid distensibility. After 24 weeks of statin therapy, CoQ10 levels decreased (p = 0.002 for between group difference) and CoQ10/LDL ratio increased (p = 0.036). In the statin treatment arm, we did not find evidence of a relationship between changes in CoQ10 or CoQ10/LDL ration and changes in markers of inflammation or immune activation. There was a borderline statistically significant association between changes in CoQ10 and myalgia symptoms [OR 4.0 per 0.1 mg/L decrease in CoQ10, p = 0.07].ConclusionTwenty-four weeks of 10 mg daily rosuvastatin decreases CoQ10 concentration and increases CoQ10/LDL ratio in HIV-infected patients on antiretroviral therapy.

Project description:BackgroundTherapy with tenofovir is associated with lower bone mineral density (BMD), higher markers of bone turnover and increased fracture risk in HIV-infected adults. Bone structural parameters generated by hip structural analysis may represent a separate measure of bone strength, but have not been assessed in HIV.MethodsDual-energy X-ray absorptiometry (DXA) scans from 254 HIV-infected adults randomised to simplify their existing dual nucleoside analogue reverse transcriptase inhibitor therapy to coformulated tenofovir-emtricitabine or abacavir-lamivudine were analysed using DXA-derived hip structural analysis software. Hip structural parameters included femoral strength index, section modulus, cross-sectional area, and cross-sectional moment of inertia. We used one-way ANOVA to test the relationship between nucleoside analogue type at baseline and structural parameters, multivariable analysis to assess baseline covariates associated with femoral strength index, and t-tests to compare mean change in structural parameters over 96 weeks between randomised groups.ResultsParticipants taking tenofovir at baseline had lower section modulus (-107.3 mm2, p = 0.001), lower cross-sectional area (-15.01 mm3, p = 0.001), and lower cross-sectional moment of inertia (-2,036.8 mm4, p = 0.007) than those receiving other nucleoside analogues. After adjustment for baseline risk factors, the association remained significant for section modulus (p = 0.008) and cross-sectional area (p = 0.002). Baseline covariates significantly associated with higher femoral strength index were higher spine T-score (p = 0.001), lower body fat mass (p<0.001), lower bone alkaline phosphatase (p = 0.025), and higher osteoprotegerin (p = 0.024). Hip structural parameters did not change significantly over 96 weeks and none was significantly affected by treatment simplification to tenofovir-emtricitabine or abacavir-lamivudine.ConclusionIn this population, tenofovir use was associated with reduced composite indices of bone strength as measured by hip structural analysis, but none of the structural parameters improved significantly over 96 weeks with tenofovir cessation.Trial registrationClinicalTrials.gov NCT00192634.
