Cholesterol levels in HIV-HCV infected patients treated with lopinavir/r : results from the SCOLTA project.

Background: It is not known whether antiretroviral therapy (ART) including lopinavir/r has a different effect on the lipid metabolism in HIV patients co-infected with HCV. This study investigated changes in lipid levels, comparing patients with HIV infection alone and those with HCV too, in the lopinavir/r cohort of the SCOLTA project. Methods: We analyzed the data for the lopinavir/r nationwide cohort from 25 Italian infectious disease departments, which comprises 743 HIV-infected patients followed prospectively, comparing subjects with HIV-HCV co-infection and those with single-infection. Results: At enrolment, co-infected patients had significantly lower mean cholesterol than HCV negative cases (162 \ub1 43 mg/dL vs. 185 \ub1 52 mg/dL, p = 0.0009). Total and non-HDL cholesterol and triglycerides rose significantly from baseline in HIV single-infection patients, but not in those with co-infection. The patients with dual HIV-HCV infection, treated with an ART regimen including lopinavir/r, have only limited increases in total and non-HDL cholesterol and triglycerides. Conclusions: Changes in serum lipids in co-infected patients differed significantly from those in patients without HCV. It remains to be seen whether this is associated with a lower risk of progression of atherosclerotic disease

Symmetric ambulatory arterial stiffness index and 24-h pulse pressure in HIV infection: results of a nationwide cross-sectional study.

OBJECTIVE:: HIV infection has been associated with increased cardiovascular risk. Twenty-four-hour ambulatory blood pressure (BP) is a more accurate and prognostically relevant measure of an individual's BP load than office BP, and the ambulatory BP-derived ambulatory arterial stiffness index (AASI) and symmetric AASI (s-AASI) are established cardiovascular risk factors. METHODS:: In the setting of the HIV and HYpertension (HIV-HY) study, an Italian nationwide survey on high BP in HIV infection, 100 HIV-infected patients with high-normal BP or untreated hypertension (72% men, age 48 ± 10 years, BP 142/91 ± 12/7 mmHg) and 325 HIV-negative individuals with comparable age, sex distribution, and office BP (68% men, age 48 ± 10 years, BP 141/90 ± 11/8 mmHg) underwent 24-h ambulatory BP monitoring. RESULTS:: Despite having similar office BP, HIV-infected individuals had higher 24-h SBP (130.6 ± 14 vs. 126.4 ± 10 mmHg) and pulse pressure (49.1 ± 9 vs. 45.9 ± 7 mmHg, both P < 0.001), and a lower day-night reduction of mean arterial pressure (14.3 ± 9 vs. 16.3 ± 7%, P = 0.025). Both s-AASI and AASI were significantly higher in HIV patients (s-AASI, 0.22 ± 0.18 vs. 0.11 ± 0.15; AASI, 0.46 ± 0.22 vs. 0.29 ± 0.17; both P <0.001). In a multivariate regression, s-AASI was independently predicted by HIV infection (β = 0.252, P <0.001), age, female sex, and 24-h SBP. In HIV patients, s-AASI had an inverse relation with CD4 cell count (Spearman's ρ -0.24, P = 0.027). CONCLUSION:: Individuals with HIV infection and borderline or definite hypertension have higher symmetric AASI and 24-h systolic and pulse pressures than HIV-uninfected controls matched by office BP. High ambulatory BP may play a role in the HIV-related increase in cardiovascular risk

Improvement of lipid profile after switching from efavirenz or ritonavir-boosted protease inhibitors to rilpivirine or once-daily integrase inhibitors: results from a large observational cohort study (SCOLTA)

Abstract Background Dyslipidemia represents a significant non-infectious comorbidity among people living with HIV. The aim of this study is to evaluate the impact on lipid profile of switches from an efavirenz (EFV) or protease inhibitor/ritonavir (PI/r)-based regimen to a rilpivirine (RPV) or a once-daily integrase inhibitor-based regimen. Methods We analyzed data from SCOLTA prospective database. All patients with HIV-RNA < 50 copies/ml in therapy with two NRTI + EFV or PI/r were included if they switched from EFV to dolutegravir (group EFV-DTG), elvitegravir (EFV-EVG), or RPV (EFV-RPV) and from PI/r to DTG (PI/r-DTG), PI/r to EVG (PI/r-EVG), or PI/r to RPV (PI/r-RPV). Total cholesterol (TC), TC/HDL ratio, LDL-cholesterol (LDL) and triglycerides (TG) were compared at baseline, six months and one year. Comparisons among groups were performed by a general linear model. Results Four hundred and ninety patients were enrolled, 24.9% female, mean age 47.3 years (±10.1). According to ART switch, 11.4% were classified in group EFV-DTG, 3.9% in EFV-EVG, 23.9% in EFV-RPV, 17.6% in PI/r-DTG, 17.8% in PI/r-EVG, and 25.5% in PI/r-RPV. After adjusted analysis, TC significantly decreased in all groups but EFV-EVG, TC/HDL in all but EFV-DTG and EFV-EVG, while the reduction of TG was significant only in switches to RPV (EFV-RPV and PI/r-RPV). The one year decrease of TC, TC/HDL, LDL and TG was higher in patients with higher baseline levels of the same variable (p < .0001 for all). Conclusions In SCOLTA, all switches from PI/r regimens gave advantages on lipid profile, while stopping EFV had consistently favorable lipid effects only if replaced by RPV

Positioning of darunavir/cobicistat-containing antiretroviral regimens in real life: results from a large multicentre observational prospective cohort (SCOLTA).

Background: Study aim was to evaluate the safety and durability of darunavir/cobicistat (DRV/c) in a real life setting. Methods: Multicentre prospective cohort study performed in the context of SCOLTA (Surveillance Cohort Long-Term Toxicity Antiretrovirals). Patients were evaluated at baseline, week 24 and 48. Changes were evaluated using the paired t test or signed rank test. The multivariable analysis was performed using a general linear model, after ranking of not normally distributed variables. Results: A total of 249 patients were included, 72 (29%) were in DRV/c-based dual therapies (DT). Hypercholesterolemia, HC, (total cholesterol (TC) 65 200 mg/dL or low density-C (LDL-C) 65 130 or statin use) was present in 121 (48.6%) and hypertriglyceridemia, (triglycerides (TG) 65 200 mg/dl or fibrate use) in 41 (16.5%) patients. Blood lipid profile did not change significantly in either the global population or patients with HC. After a median observation of 17 months (IQR 13\u201320), 59 (25.3%) patients discontinued DRV/c, of which 13 were in DT. The durability DT resulted higher than that of triple therapy (log-rank test p = 0.01). Main reasons for stopping DRV/c were simplification (15 patients), adverse events (13 patients), planned discontinuation for treatment initiation with DAA (4 patients), treatment failure (2 patients); death (2 patients), other causes (10 patients). Twenty-six were lost to follow-up. Conclusions: DRV/c was safe and well tolerated. Dual therapies showed a better profile of tolerability and a longer durability compared to triple therapies

Safety and tolerability of Elvitegravir/ Cobicistat/Emtricitabine/Tenofovir Disoproxil fumarate in a real life setting: Data from surveillance cohort long-term toxicity antiretrovirals/antivirals (SCOLTA) project

Objectives: The study aim was to evaluate the impact on Liver and Kidney toxicity of the single tablet regimen Elvitegravir/Cobicistat/Emtricitabine/Tenofovir Disoproxil Fumarate (EVG/COBI/ FTC/TDF) on Antiretroviral Therapy (ART) experienced or naïve patients. Methods: Patients initiating EVG/COBI/FTC/TDF were enrolled in the SCOLTA project, a multicenter observational study reporting grade 3–4 Adverse Events in subjects beginning new antiretroviral drug regimens. In this analysis, patients were evaluated at T0 (baseline), T1 (six months) and at T2 (twelve months). Results: A total of 329 patients were enrolled, and 280 (85.1%) of these had at least one follow-up visit. Median observation time was 11 months (IQR 7.0–15.5). Two hundred and two patients (72.1%) were ART experienced and 78 (27.9%) ART naive. Prevalence of HCV-coinfection was 21.4%. At T1, we observed a significant decline in estimated glomerular filtration rate (eGFR), both in experienced and naive patients (mean change from T0–7.5 ± 12.8 ml/min, -15.5 ± 17.8 ml/min, respectively, p = 0.0005), which was confirmed at T2 (mean change from T0–8.2 ± 15.8 ml/min, -17.6 ± 19.4 ml/min, respectively, p = 0.001). Regarding aspartate aminotransferase (AST) and alanine transaminase (ALT) grade 1–2 modifications, no significant differences were observed between experienced and naïve subjects, but an increased prevalence of abnormal liver function test was observed in patients with chronic HCV infection (p&lt;0.001). Conclusions: A significant decline in eGFR was observed in patients initiating EVG/COBI/FTC/TDF in the first 6 months, with no significant worsening occurring at 12 months vs. 6 months of therapy. Patients with chronic HCV infection were at higher risk to develop abnormal liver tests
