BACKGROUND: Cardiovascular disease (CVD) is an emerging concern for HIV-infected patients. Hyperlipidaemia is a risk factor for CVD and a complication of protease-inhibitor-based antiretroviral therapy, but little is known about its incidence and risk factors in treated patients in resource-limited settings (RLS). METHODS: We conducted a secondary analysis of ACTG A5230 trial in which HIV-infected adults from India, Malawi, Tanzania, Thailand and South Africa, with virological relapse on first-line therapy were initiated on lopinavir/ritonavir (LPV/r) monotherapy...

BACKGROUND: The role of oxidized lipoproteins (high-density [HDLox] and low-density [LDLox]) and total lipoprotein particle (Lp) number and size in HIV-related cardiovascular disease (CVD) is unclear. The goal of this study was to evaluate changes of these biomarkers and their associations with rate of carotid intima media thickness progression over 3 years (ΔCIMT) in chronic HIV infection. METHODS: Prospective study of 234 HIV-infected antiretroviral treatment-naive participants without CVD who were randomized to receive tenofovir-emtricitabine plus atazanavir/ritonavir, darunavir/ritonavir or raltegravir (RAL) and achieved plasma HIV-1 RNA <50 copies/ml by week 24 and thereafter...

OBJECTIVE: The pathogenesis of immune dysfunction in chronic HIV-1 infection is unclear, and a potential role for oxidized lipids has been suggested. We hypothesize that both oxidized HDL and LDL (HDLox and LDLox) contribute to HIV-1-related immune dysfunction. STUDY: In the AIDS Clinical Trials Group A5260, 234 HIV-infected antiretroviral therapy (ART)-naive participants were randomized to receive tenofovir-emtricitabine and protease inhibitors or raltegravir and had HIV-1 RNA less than 50 copies/ml by week 24 and thereafter...

BACKGROUND AND OBJECTIVE: Diabetes mellitus (DM) is common in human immunodeficiency virus (HIV)-infected patients. However, the relationship between dysglycemia, lipid metabolism, and immune activation in HIV patients is poorly understood. METHODS: We retrospectively analyzed the clinical data of 180 HIV patients, including 153 patients undergoing highly active antiretroviral therapy (HAART) and 27 HAART-naive patients. DM was defined as fasting serum glucose levels ≥126 mg/dl, and impaired fasting glucose (IFG) was defined as serum glucose levels of 101-125 mg/dl at two different time points...

BACKGROUND: Dyslipidemia as a risk factor of cardiovascular disease is common especially in HIV-infected patients who are using protease inhibitors (PIs) including atazanavir. Pitavastatin has less drug-drug interactions and demonstrable efficacy in decreasing lipid levels in non HIV-infected individuals. MATERIALS AND METHODS: This study was a randomized, double-blind, crossover study comparing the safety and efficacy of pitavastatin vs placebo in HIV-infected patients with dyslipidemia and receiving atazanavir/ritonavir (ATV/r)...

BACKGROUND: HIV patients on highly-active antiretroviral therapy (HAART) have shown elevated incidence of dyslipidemia, lipodystrophy, and markers of cardiovascular disease. Evidence is beginning to emerge that implicates efavirenz (EFV) as a potential mediator of early on-set cardiovascular disease. METHODS: Pediatric and adult HIV-infected HAART-naïve, EFV-treated, nevirapine (NVP)-treated, and ritonavir-boosted lopinavir (LPV/r)-treated subjects were recruited from Black Lion Hospital in Addis Ababa, Ethiopia...

The hypothesis of the present study is that the polymorphisms in the APOC3, CEPT, ACE, and ACTN3 genes can affect the outcome of nutritional intervention and the plasma lipid profile of HIV+ patients. To test the hypothesis, genetic material was collected from buccal cells, and serum was collected for biochemical analysis. Sixty-five patients were analyzed. The incorporation of protease inhibitor (PI) was more frequent in women (77% vs 33% in men). Nutritional intervention improved anthropometric parameters independent of the genotype...

BACKGROUND: Functional abnormalities of high-density lipoprotein (HDL) could contribute to cardiovascular disease in chronic kidney disease patients. We measured a validated marker of HDL dysfunction, nitrated apolipoprotein A-I, in kidney transplant recipients to test the hypothesis that a functioning kidney transplant reduces serum nitrated apoA-I concentrations. METHODS: Concentrations of nitrated apoA-I and apoB were measured using indirect sandwich ELISA assays on sera collected from each transplant subject before transplantation and at 1, 3, and 12 months after transplantation...

BACKGROUND AND AIMS: Coronary artery disease is a growing clinical problem in HIV-infected subjects. The increased risk of coronary events in this population has been linked to low levels of HDL, but the effects of HIV infection and anti-retroviral treatment (ART) on HDL structure and function remain unknown. Here, we aimed to determine the composition and function of HDL particles isolated from ART-naive and ART-positive HIV-infected patients. METHODS AND RESULTS: Proteomic profiling revealed decreased levels of paraoxonase (PON) 1 and PON 3 in HDL from HIV patients relative to HDL from uninfected controls (p < 0...

INTRODUCTION: Switching to a rilpivirine, tenofovir and emtricitabine (RTE) single-tablet regimen (STR) has been evaluated in a limited number of virologically suppressed patients. The aim of this study was to describe clinical outcomes in HIV-positive patients switched from a suppressive antiretroviral regimen to RTE STR in routine clinical practice. METHODS: In this retrospective study of antiretroviral-treated patients with <50 copies of HIV RNA/mL switched to RTE STR, virological failure (VF) was defined as two consecutive measurements of ≥50 copies/mL or a single measurement of ≥50 copies/mL followed by any change in treatment...

BACKGROUND: Lifestyle changes and statins are the cornerstones in management of dyslipidaemia in patients with HIV infection. Replacement of an antiretroviral therapy (ART) component is a proposed therapeutic strategy to reduce cardiovascular risk. In dyslipidaemic patients with HIV infection, we assessed the efficacy of replacing boosted protease inhibitor (bPI) or efavirenz (EFV) by etravirine (ETR) as an alternative to statin therapy. MATERIALS AND METHODS: A prospective, open-label, multicentre, 12-week study of patients with HIV infection on ART including bPI or EFV, and statin treatment...

OBJECTIVE: HIV-infected participants are at a higher risk for cardiovascular disease (CVD). N-terminal pro-B-type natriuretic peptide (NT-proBNP) is a significant predictor of CVD in the general population and is associated with mortality in HIV. DESIGN AND METHODS: The 96-week Stopping Atherosclerosis and Treating Unhealthy Bone with Rosuvastatin in HIV (SATURN-HIV) trial randomized 147 patients on stable antiretroviral therapy with low-density lipoprotein-cholesterol level lower than 130 mg/dl and without overt heart failure to 10 mg daily rosuvastatin or placebo...

Dyslipidemia and lipodystrophy represent significant healthcare concerns in HIV-infected patients due to their association with diabetes mellitus and increased cardiovascular disease risk. Since the lipid effects of the nonnucleoside reverse transcriptase inhibitors are not well characterized, we systematically summarized the effects of nonnucleoside reverse transcriptase inhibitor treatment on dyslipidemia and lipodystrophy in HIV-1 infection. As with other classes of antiretroviral agents, the nonnucleoside reverse transcriptase inhibitors are associated with lipid changes, although individual agents exhibit differing effects on lipid profiles...
