BACKGROUND: HIV-infected children receiving antiretroviral therapy (ART) have increased prevalence of hyperlipidemia and risk factors for cardiovascular disease. No studies have investigated the efficacy and safety of statins in this population. METHODS: HIV-infected youth aged 10 - < 24 years on stable ART with low-density lipoprotein-cholesterol (LDL-C) ≥130 mg/dL for ≥ 6 months initiated atorvastatin 10mg once daily. Atorvastatin was increased to 20mg if LDL-C efficacy criteria (LDL-C < 110 mg/dL or decreased ≥30% from baseline) were not met at week 4...

Cardiovascular disease (CVD) is increasingly common among women with HIV, but literature on nonlipid CVD risk factor management is lacking. We examined semiannual trends from 2006 to 2014 in hypertension treatment and control (blood pressure <140/90 mmHg), diabetes treatment and control (fasting glucose <130 mg/dL), and smoking quit rates in the Women's Interagency HIV Study. Unadjusted and adjusted Poisson regression models tested time trends and differences between HIV+ and HIV- women. Among antiretroviral therapy (ART) users, we examined the association of ART adherence and virologic suppression with each outcome...

Long-term use of antiretroviral therapy (ART) increases the risk of developing lipodystrophy. Few studies from Africa have used longitudinal data to assess the development of lipoatrophy and lipohypertrophy. We use clinical anthropometry and dual-energy X-ray absorptiometry (DEXA) to describe changes in body fat distribution over a 24-month period in individuals initiated on ART. A convenience sample of black South Africans (55 men and 132 women) were recruited and followed for 24 months after commencing ART...

BACKGROUND: Persons infected with HIV often have altered lipid profiles that may be affected by antiretroviral therapies (ART). Traditional lipid measurements may be insufficient to assess cardiovascular disease (CVD) risk in this population. METHODS: We report results from 39 ART-naïve participants in a substudy of A5248, a single-arm study of raltegravir (RAL), emtricitabine/tenofovir administration. Samples were collected at baseline, 12, 24, and 48 weeks after ART initiation...

Effective combination antiretroviral therapy (ART) has enabled human immunodeficiency virus (HIV) infection to evolve from a generally fatal condition to a manageable chronic disease. This transition began two decades ago in high-income countries and has more recently begun in lower income, HIV endemic countries (HIV-ECs). With this transition, there has been a concurrent shift in clinical and public health burden from AIDS-related complications and opportunistic infections to those associated with well-controlled HIV disease, including cardiovascular disease (CVD)...

Highly active antiretroviral therapy (ART) has allowed a long-term control of viral replication and HIV infection has been transformed into a chronic disease. However, ART is not able to eradicate the virus, and high levels of inflammation and immune-activation are observed despite prolonged ART. Consequently, a number of comorbidities, such as cardiovascular diseases and cancer, are gaining relevance in patients living with HIV. Moreover, the toxicities associated with continued exposure to ART cause several metabolic disturbances with clinical relevance, and the cost of treatment is a heavy burden for the national health systems...

Increases in inflammation, coagulation, and CD8 T cell numbers are associated with elevated cardiovascular disease (CVD) risk in antiretroviral therapy (ART)-treated HIV infection. Circulating memory CD8 T cells that express the vascular endothelium-homing receptor CX3CR1 (fractalkine receptor) are enriched in ART-treated HIV-infected subjects. Thrombin-activated receptor (PAR-1) expression is increased in ART-treated HIV-infected subjects and is particularly elevated on CX3CR1+ CD8 T cells, suggesting that these cells could interact with coagulation elements...

BACKGROUND: Cardiovascular disorders are common in HIV-1 infected persons in Africa and presentation is often insidious. Development of screening algorithms for cardiovascular disorders appropriate to a resource-constrained setting could facilitate timely referral. Cardiothoracic ratio (CTR) on chest radiograph (CXR) has been suggested as a potential screening tool but little is known about its reproducibility and stability. Our primary aim was to evaluate the stability and the inter-observer variability of CTR in HIV-1 infected outpatients...

OBJECTIVE: In 2015, the World Health Organization (WHO) recommended initiation of antiretroviral therapy (ART) in all HIV-positive patients regardless of CD4 cell count. We evaluated the cost-effectiveness of immediate versus deferred ART initiation among patients with CD4 counts exceeding 500 cells/mm in four resource-limited countries (South Africa, Nigeria, Uganda, and India). DESIGN: A 5-year Markov model with annual cycles including patients at CD4>500 cells/mm initiating ART or deferring therapy until historic ART initiation criteria of CD < 350 cells/mm were met...

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 naïve 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...

INTRODUCTION BACKGROUND TO METABOLOMICS: Metabolomics is the comprehensive study of the metabolome, the repertoire of biochemicals (or small molecules) present in cells, tissues, and body fluids. The study of metabolism at the global or "-omics" level is a rapidly growing field that has the potential to have a profound impact upon medical practice. At the center of metabolomics, is the concept that a person's metabolic state provides a close representation of that individual's overall health status...

BACKGROUND: Lopinavir/ritonavir (LPV/r) is widely used in Cambodia with high efficacy but scarce data exist on long-term metabolic toxicity. METHODS: We carried out a cross-sectional and retrospective study evaluating metabolic disorders and cardiovascular risk in Cambodian patients on LPV/r-based antiretroviral therapy (ART) for > 1 year followed in Calmette Hospital, Phnom Penh. Data collected included cardiovascular risk factors, fasting blood lipids and glucose, and retrospective collection of bioclinical data...

In the current era of available therapy for human immunodeficiency virus (HIV), life expectancy for persons living with HIV (PLWH) nears that of the general population. Atherosclerotic cardiovascular disease (ASCVD) has become a particular burden for PLWH and society at large. PLWH have historically been shown to have an excess of cardiovascular risk and subsequent events when compared to the general population. Potential explanations include the increased prevalence of traditional risk factors, direct inflammatory and immunological effects from the HIV virus itself, and metabolic adverse effects of anti-retroviral therapy (ART)...

We examined factors associated with selection of initial antiretroviral regimen in the CNICS cohort. Patients initiating antiretroviral therapy (ART) between July 2009 and Dec 2012 were classified as receiving an NNRTI, boosted-PI, or raltegravir-based regimen. Among 873 patients initiating ART, 488 regimens contained an NNRTI, 319 a boosted-PI, and 66 raltegravir. Patients with depression and women were less likely to receive an NNRTI, while those with underlying cardiovascular disease, liver disease, and those co-infected with hepatitis C were more likely to receive raltegravir...

OBJECTIVES: To study the association between CD4/CD8 ratio and morbidity in HIV-infected patients on antiretroviral therapy (ART). METHODS: The APROCO/COPILOTE cohort enrolled patients initiating a protease inhibitor-containing ART in 1997-1999. The association between occurrence of first non AIDS-defining severe events (NADE) and time-dependent measures of immune restoration was assessed by 4 Cox models with different definitions of restoration, CD4+ cell counts (CD4), CD4/CD8 ratio, both CD4 and CD4/CD8 ratio, or a composite variable (CD4< 500/mm3, CD4 > 500/mm3 and CD4/CD8 ratio < 1, CD4 > 500/mm3 and CD4/CD8 ratio > 1)...

HIV infection and antiretroviral therapy (ART) use are associated with perturbations in glucose and lipid metabolism. Increasing incidence of diabetes, cardiovascular disease, and obesity highlights the need for early identification and treatment of metabolic dysfunction. Newer ART regimens are less toxic for cellular function and metabolism but have failed to completely eliminate metabolic dysfunction with HIV infection. Additional factors, including viral-host interactions, diet, physical activity, non-ART medications, and aging may further contribute to metabolic disease risk in the HIV setting...

HIV-infected individuals are at increased risk of cardiovascular disease, but the arterial vascular functions affected by persistent innate and cellular immune activation are not well described. We assessed the relationship between immunologic and vascular parameters in 70 HIV-infected adults on efavirenz, tenofovir, and emtricitabine with over 2 years of virologic suppression and no history of cardiovascular disease. We measured brachial artery flow mediated dilation (FMD) using ultrasound, and circulating intercellular adhesion molecule 1 (ICAM-1) and vascular cell adhesion molecule 1 (VCAM-1) by multiple immunoassay...

OBJECTIVES: To estimate mortality rates and prognostic factors in HIV-positive patients who started combination antiretroviral therapy between 1996-1999 and survived for more than ten years. METHODS: We used data from 18 European and North American HIV cohort studies contributing to the Antiretroviral Therapy Cohort Collaboration. We followed up patients from ten years after start of combination antiretroviral therapy. We estimated overall and cause-specific mortality rate ratios for age, sex, transmission through injection drug use, AIDS, CD4 count and HIV-1 RNA...

The number of people living with HIV and AIDS (PLWHA) reached to almost 40 million, half of which are under antiretroviral treatment (ART). Although the introduction of this therapy significantly improved the life span and quality of PLWHA, metabolic complications of these people remains to be an important issue. These metabolic complications include hyperlipidemia, abnormal fat redistribution and diabetes mellitus, which are defined as lipodystrophy syndrome. Glucagon-like peptide-1 (GLP-1) is a neuropeptide secreted from intestinal L cells and recently developed GLP-1 receptor agonists (GLP-1RAs) stimulate insulin secretion, improve weight control and reduce cardiovascular outcomes...

BACKGROUND: Cardiovascular disease (CVD) contributes to excess morbidity and mortality in HIV infection, and endothelial dysfunction may contribute to this pattern. We aimed to determine endothelial function in treated and untreated HIV-infected individuals and investigate potential associations with viral replication, immune activation, coagulation, platelet function, and subclinical atherosclerosis. METHODS: Asymmetric dimethylarginine (ADMA, marker of endothelial dysfunction) and soluble CD14 (sCD14, marker of monocyte activation) were measured in plasma from two previously established cross-sectional cohorts: Cohort A including 50 untreated and 50 anti-retroviral therapy (ART) treated HIV-infected individuals with previously assessed coagulation and platelet function, and Cohort B including 105 HIV-infected individuals on ART and 105 uninfected controls with previously assessed coronary artery calcium score (CACS), myocardial perfusion defects (MPD), and carotid intima-media thickness (cIMT)...
