Abstract
Objective: In people living with HIV (PLWH), antiretroviral treatments have increased the median life expectancy. Raltegravir (RAL) represents a long-term safe regimen used both in the first-line antiretroviral treatments and in the optimization strategies. Aim of the study was to evaluate the real-life efficacy, tolerability, and safety of the long-term RAL use in a multicenter cohort of elderly PLWH.Methods: A 60-month follow-up observational study was carried out in the RAL-AGE Cohort including aged PLWH (≥60 years old) treated with RAL-based regimens (n = 96). The control group was a cohort of PLWH aged less than 60 years (n = 50).Results: RAL treated aged HIV population experiences an increase of CD4+ cells and a stable control of viral load at 60 months of follow-up. A significant improvement in lipid metabolism profile, a decrease of platelet count and a reduction in cardiovascular risk levels were observed in the older population. Immune activation markers expressed on CD4+ T cells decreased compared to baseline, but this difference was greater in the control group.Conclusion: A 60-month treatment with RAL-containing regimens is safe and highly effective in the older PLWH and these data give new insights on the elderly population.Clinical trial registration: NCT02765776 and NCT03579485.

Abstract
OBJECTIVE Persistent immune activation is thought to contribute to increased cardiovascular disease risk in HIV and statins may help modulate systemic immune activation. We aimed to compare the effects of two key statins on markers of systemic immune activation and arterial inflammation in the HIV population. DESIGN Double-blind, active-controlled, parallel-group comparative trial performed in 45 sites. METHODS Two hundred and fifty-two antiretroviral therapy-treated HIV-infected participants with dyslipidemia were randomized (1 : 1) to pitavastatin 4 mg daily vs. pravastatin 40 mg daily in the HIV-infected patieNts and TREatment with PItavastatin vs. pravastatin for Dyslipidemia (INTREPID) trial. In this analysis of the INTREPID trial, we assessed markers of immune activation and arterial inflammation using a modified intent-to-treat population. This trial is registered with ClinicalTrials.gov (NCT01301066). RESULTS One hundred and twenty-six participants were randomized to receive pitavastatin and 126 to pravastatin. Ninety-nine participants in the pitavastatin group and 91 participants in the pravastatin group completed the study. Median age was 50 (45, 56) years [median (interquartile range)]. Baseline, low-density lipoprotein-cholestrol (LDL-C) was 153 (135, 171) mg/dl, log HIV-1 viral load was 1.1 ± 0.2 copies/ml, and CD4 cell count was 580 (439, 794) cells/μl. At week 52, the pitavastatin group had a significantly greater reduction (% change) compared with pravastatin in soluble CD14 (sCD14), (-10.0 vs. 0.6%, P = 0.02), oxidized LDL (oxLDL) (-26.9 vs. -17.5%, P = 0.02), and lipoprotein-associated phospholipase 2 (Lp-PLA2) (-26.6 vs. -15.5%, P = 0.005) (pitavastatin vs. pravastatin). CONCLUSION Fifty-two weeks of pitavastatin 4 mg daily (vs. pravastatin 40 mg daily) led to a greater reduction in select markers of immune activation and arterial inflammation (sCD14, oxLDL, and LpPLA2) among HIV-infected participants. Further work is needed to assess whether immune-modulatory effects of pitavastatin reduce cardiovascular disease risk in HIV.
