Intracellular bacteria were recently shown to employ eukaryotic prenylation system for modifying activity and ensuring proper intracellular localization of their own proteins. Following the same logic, the proteins of viruses may also serve as prenylation substrates. Using extensively validated high-confidence prenylation predictions by PrePS with a cut-off for experimentally confirmed farnesylation of hepatitis delta virus antigen, we compiled in silico evidence for several new prenylation candidates, including IRL9 (CMV) and few other proteins encoded by Herpesviridae, Nef (HIV-1), E1A (human adenovirus 1), NS5A (HCV), PB2 (influenza), HN (human parainfluenza virus 3), L83L (African swine fever), MC155R (molluscum contagiosum virus), other Poxviridae proteins, and some bacteriophages of human associated bacteria...

BACKGROUND: Little is known about the use of statin for cardiovascular disease (CVD) risk reduction among HIV-infected patients on protease inhibitors (PI`s) in sub-Saharan Africa (SSA). OBJECTIVE: Cholesterol screening and statin use were retrospectively assessed among HIV-infected participants on PI`s between 2008 and 2012 at a large urban HIV clinic in Botswana. METHODS: Proportion of participants screened per year was calculated and statin indication was assessed using atherosclerosis CVD (ASCVD) and Framingham risk (FRS) scores as of the year 2012 guidelines...

PURPOSE OF REVIEW: The aim of this study was to discuss the most recent research in the management of cardiovascular disease (CVD) in people living with HIV (PLWHIV) with a focus on screening, primary and secondary prevention. RECENT FINDINGS: The cause of CVD in PLWHIV is complex and multifactorial and creates a demand for a multifaceted approach to screening and prevention. Current screening and management of CVD risk factors in PLWHIV is suboptimal, reasons for this are not clear and the data are still scarce both in the primary and secondary preventive setting...

Treated human immunodeficiency virus (HIV) infection is characterized by ectopic fat deposition, a persistent inflammatory state, and increased cardiometabolic risk. In this secondary analysis of a placebo controlled trial of rosuvastatin among 147 HIV+ subjects (median age 46; 78% men) on stable antiretroviral therapy, we aimed to evaluate longitudinal associations between computed tomography (CT) measures of pericardial fat (PCF) volume and density, insulin resistance, and inflammation. We measured PCF volume and density (mean attenuation in Hounsfield units) by noncontrast gated CT at baseline and week 96...

BACKGROUND: Aim of this review is to focus the attention on people living with HIV infection at risk of developing a cardiovascular event. What is or what would be the most suitable antiretroviral therapy? Which statin or fibrate to reduce the risk? How to influence behavior and lifestyles? DISCUSSION: Prevention of cardiovascular disease (CVD) risk remains the first and essential step in a medical intervention on these patients. The lifestyle modification, including smoking cessation, increased physical activity, weight reduction, and the education on healthy dietary practices are the main instruments...

Cardiovascular disease (CVD) has a higher incidence in patients with HIV infection. This study sought to determine whether HIV-infected patients with established CVD were being managed according to national guidelines. Data were collected from Australian general practitioners for 77 HIV-infected patients with a median age of 59 (range 54-64). There was good adherence to guidelines with regards to anti-platelet (84%; n=65; 95% confidence interval (CI) 74-92%) and statin therapy (97%; n=75; 95% CI 91-100%), despite a failure to meet cholesterol targets, with only 31% (n=24; 95% CI 21-42%) of the cohort meeting low-density lipoprotein target values...

BACKGROUND: Treated HIV infection is associated with heightened inflammation which can contribute to increased risk of cardiovascular disease (CVD). We have previously shown that anisocytosis, as measured by red cell distribution width (RDW), is independently associated with prevalent CVD in people living with HIV (PLHIV). In this study, we sought to identify immune correlates of RDW in PLHIV receiving antiretroviral therapy. METHODS: We performed a cross-sectional and longitudinal analysis of 147 virally-suppressed PLHIV, who had LDL < 130 mg/dL and evidence of heightened inflammation, in a randomized trial of statin therapy...

OBJECTIVE: Whether the rate of HIV antiretroviral therapy (ART) persistence has improved over time in the United States is unknown. We examined ART persistence trends between 2001 and 2010, using non-HIV medications as a comparator. METHODS: We conducted a retrospective cohort study using Medicaid claims. We defined persistence as the duration of treatment from the first to the last fill date before a 90-day permissible gap and used Kaplan-Meier curves and Cox proportional hazard models to assess crude and adjusted nonpersistence...

BACKGROUND: Although HIV is associated with increased atherosclerotic cardiovascular disease (CVD) risk, it is unknown whether guidelines can identify HIV-infected adults who may benefit from statins. We compared the 2013 American College of Cardiology/American Heart Association and 2004 Adult Treatment Panel III recommendations in HIV-infected adults and evaluated associations with carotid artery intima-media thickness and plaque. METHODS AND RESULTS: Carotid artery intima-media thickness was measured at baseline and 3 years later in 352 HIV-infected adults without clinical atherosclerotic CVD and not on statins...

BACKGROUND: Pathogenesis of atherosclerosis is complex and differences between HIV-infected patients and general population cannot be completely explained by the higher prevalence of traditional cardiovascular risk factors. We aimed to analyse the association between inflammation and subclinical atherosclerosis in HIV patients with low Framingham risk score. MATERIALS AND METHODS: Case-control study.

BACKGROUND: People living with HIV-1 infection are at greater risk for cardiovascular disease than seronegative adults. Treatment of dyslipidaemia with statins has been challenging in people with HIV because of an increased potential for drug interactions due to competing cytochrome P450 metabolism between statins and commonly used antiretroviral agents. Neither pitavastatin nor pravastatin depend on cytochrome P450 for primary metabolism. We aimed to assess the safety and efficacy of pitavastatin versus pravastatin in adults with HIV and dyslipidaemia...

The discovery of antiretroviral therapy (ART) for the treatment of human immunodeficiency virus (HIV) has enabled individuals to live longer. As a result, HIV is now often considered a chronic condition. However, as a result of the increase in longevity or the HIV treatment modalities themselves, individuals with HIV are at high risk for the development of atherosclerotic cardiovascular disease. Therefore, these patients should be optimized with pharmacologic therapy to lower their cardiovascular risk through the addition of statin therapy to their regimen...

PURPOSE OF REVIEW: Introduction of combination antiretroviral therapy (ART) has increased the life expectancy of patients with HIV infection, allowing them to live longer with this chronic medical condition and consequently experiencing conditions such as cardiovascular diseases (CVDs). Several studies have investigated the increased risk of CVD in people living with HIV (PLWH). However, less is known about the exact mechanisms involved in this increased risk. Also, specific guidelines for management of CVD in PLWH have not been developed yet...

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...

BACKGROUND: Despite compelling evidence for activity against HIV-1 in vitro, a virologic effect of statins has not been shown in clinical studies. Given their short plasma half-lives, such an effect may be transient and only apparent during ongoing exposure. METHODS: We studied all HIV infected US-Veterans who started HAART 1995-2011, had a documented HIV viral load (VL) >1000 copies/mL, reached an undetectable VL on HAART, and had ≥1 follow-up VL within 13 months...
