Clin Ther 2024; 46:e114-e124. [PMID: 38851959 DOI: 10.1016/j.clinthera.2024.04.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2023] [Revised: 11/08/2023] [Accepted: 04/21/2024] [Indexed: 06/10/2024]
Abstract
PURPOSE Highly active antiretroviral therapy (HAART) has brought a significant reduction in HIV/AIDS-related morbidity and mortality. However, metabolic abnormalities (eg, dyslipidemias) have continued to pose significant challenges, warranting a switch between antiretroviral agents and/or the introduction of a statin. Hence, the purposes of this study was to compare the efficacy of switching between antiretroviral agents versus introducing a statin in the long-term management of HAART-induced dyslipidemia in people living with HIV, and to identify the most potent agent in switching therapies. METHODS A comprehensive literature search of PubMed and Medline identified articles published from the years 2000 to 2020 in the English language, resulting in 84 articles, 30 of which were selected based on inclusion and exclusion criteria. Information on primary and secondary outcomes was extracted. Statistical analysis was done on the variables, and the differences between groups were considered significant at P < 0.05. FINDINGS Statin use was associated with significant reductions in triglycerides and total cholesterol (TC) at 6 weeks (both, P < 0.01). A switch of antiretroviral agents was associated with gradual reductions in TC and triglycerides for up to 48 weeks (both, P < 0.01). Statin use was associated with a reduced CD4 count at 24 weeks (P < 0.01). A switch of antiretroviral agents was associated with an increased CD4 count at 48 weeks (P < 0.01). IMPLICATIONS Statins were as effective as switching antiretroviral therapies in the short-term management of TC and triglycerides in patients with HAART-induced dyslipidemia.

Abstract
Peroxisome proliferator-activated receptors (PPARs) are nuclear receptors that govern the expression of genes responsible for energy metabolism, cellular development, and differentiation. Their crucial biological roles dictate the significance of PPAR-targeting synthetic ligands in medical research and drug discovery. Clinical implications of PPAR agonists span across a wide range of health conditions, including metabolic diseases, chronic inflammatory diseases, infections, autoimmune diseases, neurological and psychiatric disorders, and malignancies. In this review we aim to consolidate existing clinical evidence of PPAR modulators, highlighting their clinical prospects and challenges. Findings from clinical trials revealed that different agonists of the same PPAR subtype could present different safety profiles and clinical outcomes in a disease-dependent manner. Pemafibrate, due to its high selectivity, is likely to replace other PPARα agonists for dyslipidemia and cardiovascular diseases. PPARγ agonist pioglitazone showed tremendous promises in many non-metabolic disorders like chronic kidney disease, depression, inflammation, and autoimmune diseases. The clinical niche of PPARβ/δ agonists is less well-explored. Interestingly, dual- or pan-PPAR agonists, namely chiglitazar, saroglitazar, elafibranor, and lanifibranor, are gaining momentum with their optimistic outcomes in many diseases including type 2 diabetes, dyslipidemia, non-alcoholic fatty liver disease, and primary biliary cholangitis. Notably, the preclinical and clinical development for PPAR antagonists remains unacceptably deficient. We anticipate the future design of better PPAR modulators with minimal off-target effects, high selectivity, superior bioavailability, and pharmacokinetics. This will open new possibilities for PPAR ligands in medicine.

Abstract
Introduction: Cardiovascular disease is an important cause of morbidity and mortality in persons with human immunodeficiency virus (PWH). The risk of atherosclerotic cardiovascular disease (ASCVD) is higher in PWH compared to uninfected persons. Dyslipidemia is a critical link in the pathogenesis of ASCVD in PWH. Chronic inflammation associated with HIV infection may drive both dyslipidemia and ASCVD. Areas covered: The authors review the evidence for using lipid-lowering therapy in PWH and includes an overview of the utility and complexity of using statins in PWH, in particular, drug interactions, safety, and efficacy. In addition, data covering alternate therapies like omega-3 fatty acids, fibrates, niacin, ezetimibe, and PCSK-9 inhibitors are reviewed. Expert opinion: Dyslipidemia is a common problem in PWH. The risk of ASCVD is higher in PWH. Lipid-lowering therapy reduces the risk of ASCVD, but clinical endpoint trials are lacking in PWH. Statin therapy is the mainstay of primary prevention for ASCVD. The timing of when to initiate primary prevention with statins in PWH is unclear. Beyond statins, there are limited data that other lipid-lowering agents have utility in PWH. Ongoing trials like the REPRIEVE trial will inform the community about the optimal approach to lipid-lowering therapy in PWH.

Abstract
OBJECTIVES An observational, prospective, cohort study was performed to compare efficacy and safety of a switch from ritonavir-boosted protease inhibitor (PI/r) to nevirapine or raltegravir with that of rosuvastatin addition to current antiretroviral therapy in HIV-infected patients with hyperlipidaemia. METHODS All HIV-infected patients receiving a stable PI/r-based antiretroviral regimen, with persistently suppressed viremia, naïve to non-nucleoside analogues and to integrase strand transfer inhibitors, with mixed hyperlipidaemia, and who underwent a switch from PI/r to nevirapine (Group A) or raltegravir (Group B) or who started rosuvastatin at 10 mg daily (group C) with unchanged antiretroviral regimen were enrolled into the study. RESULTS Overall, 136 patients were enrolled: 43 patients were included in the group A, 46 in the group B, and 47 in the group C. The mean age was 46.6 years, and 108 (79.4%) were males. After 48 weeks of follow-up, a significantly greater reduction in the mean low-density lipoprotein (LDL) cholesterol level was reported in group C (-28.2%) than in group A (-10.2%; p < .001) and B (-12.4%; p = .021), while a significantly greater reduction in the mean concentration of triglycerides was observed in group A (-31.2%) and B (-35.5%) than in group C (-11.9%; p = .034 and p = .004, respectively). The incidence of adverse events was <10% and comparable across the three groups. CONCLUSION In HIV-positive subjects receiving a PI/r, the initiation of rosuvastatin treatment after 48 weeks yielded a greater decline in LDL cholesterol, while the switch from PI/r to nevirapine or raltegravir led to a greater decline in triglycerides.

Abstract
Cardiovascular disease is up to two times more prevalent in patient with HIV. Based on pharmacokinetic and clinical data, atorvastatin and pravastatin are generally considered safe for HIV patients receiving ART. Rosuavstatin is generally safe if started at a low dose and a maximum 20 mg per day. Fluvastatin, lovastatin, and simvastatin should be avoided in patients with HIV receiving ART.
Introduction As a result of improved safe and effective therapeutic options for human immunodeficiency virus (HIV), life expectancy of those living with HIV is increasing leading to new challenges (e.g., management of chronic diseases). Some chronic diseases (e.g., cardiovascular disease [CVD]), are up to two times more prevalent in patients with HIV. Statins are a mainstay of therapy for prevention of CVD; but, clinicians should be aware that not all statins are appropriate for use in the HIV population, especially those receiving antiretroviral therapy (ART). The purpose of this article is to review the pharmacokinetic and clinical data for statin therapy in HIV-infected patients receiving ART. Methods A systematic literature search using PubMed and MEDLINE databases was performed using each statin drug name combined with HIV, pharmacokinetics, AIDS, and/or human immunodeficiency virus. English language trials published from 1946 to November 2016 were considered, and results were limited to clinical efficacy trials. Results In general, atorvastatin and pravastatin are safe and effective for patients treated with protease-inhibitor (PI) or non-nucleoside reverse transcriptase inhibitor-based ART. Rosuvastatin is generally considered safe if started at a low dose, but should be avoided if possible in patients receiving PI-based ART. Pitavastatin has limited supporting evidence, but appears safe for use based on its pharmacokinetic properties and low number of drug interactions. Fluvastatin, lovastatin, and simvastatin should be avoided in patients receiving ART due to drug interactions, adverse events, and/or limited clinical data. Conclusion Clinicians need to be familiar with the intricacies of statin selection for the prevention of CVD in patients with HIV on ART.

Abstract
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). Patients were randomized to receive either placebo or pitavastatin for 12 weeks. The follow-up visits were every 4 weeks until the end of the study. Results A total of 12 HIV-infected patients were enrolled to each study group. Of all, 14 (58%) patients were men and mean (standard deviation, SD) age was 48.1 (1.8) years. At 12 weeks of treatment with pitavastatin compared to placebo; mean [95% confidence interval (CI)] total cholesterol (TC) was 207 (187.3, 226.8) mg/dL vs 246.3 (226.5, 266) mg/dL (p <0.001); mean (95% CI) triglyceride (TG) was 351.3 (193.2, 509.4) mg/dL vs 279.1 (121, 437.2) mg/dL (p = 0.269); mean (95% CI) high density lipoprotein (HDL) was 45.3 (40.4, 50.2) mg/dL vs 44.2 (39.3, 49.1) mg/dL (p = 0.354); and mean (95% CI) low density lipoprotein (LDL) was 113.2 (100.4, 126) mg/dL vs 145.6 (132.8, 158.4) mg/dL (p <0.001). Mean liver enzyme and median creatine phosphokinase levels were not statistically significant between patients receiving placebo and pitavastatin. Conclusions Pitavastatin decreases TC and LDL level at 12 weeks significantly and shows indifferent in hepatotoxicity and creatine phosphokinase levels compared to those of placebo. Thus, pitavastatin can be a good option of lipid-lowering agent in HIV-infected patients who are receiving ATV/r. Trial Registration ClinicalTrials.gov NCT02442700

Abstract
INTRODUCTION Human immunodeficiency virus (HIV) has become a chronic disease often associated with dyslipidaemia and insulin resistance. Combination antiretroviral therapy (cART) may contribute to metabolic disturbances, eventually leading to increased cardiovascular disease (CVR) in this population. Escalating interventions to decrease CVR include promoting a healthy lifestyle, such as quitting smoking, diet and regular exercise. If they do not achieve the goals, a change of cART should be considered, followed by or used concomitantly with the use of chemical therapies. AREAS COVERED The aim of this article is to review the available drug therapies for the treatment of metabolic disorders in HIV-infected patients and to examine their safety and effectiveness in this population. A review of the literature was conducted, highlighting the most relevant articles. EXPERT OPINION Switching strategies can be useful but its expected benefit is not high. Therefore, chemical intervention is often needed. Statins have been proven to reduce CVR in the general population and in HIV-infected patients. Simvastatin is contraindicated in patients treated with boosted PI due to interactions; atorvastatin is safe at submaximal dose and needs close monitoring, while pravastatin lacks lipid-lowering potency, and rosuvastatin and pitavastatin are safe. Ezetimibe and fibrates are also safe and effective in HIV-infected patients and can be used in combination with statins. The management of glucose homeostatic disorders in HIV-infected patients follows the same guidelines as in the general population. However, there are specific considerations with respect to the interactions of particular medications with cART. When drug therapy is needed, metformin is the first-line drug. Decisions regarding second- and third-line drugs should be carefully individualized.

Abstract
HIV-infected individuals are at an increased risk of cardiovascular disease (CVD) and other HIV-related co-morbidities. This is due in part to dyslipidemia associated with antiretroviral therapy and increased inflammation and immune activation from chronic HIV infection. Statins not only have potent lipid-lowering properties but are also anti-inflammatory and immunomodulators. Studies suggest that statin therapy in the HIV-infected population may decrease the risk of CVD and other non-AIDS-defining co-morbidities. This review summarizes the recent literature on statin use in the HIV setting.

Abstract
OBJECTIVES The aim of the study was to compare the efficacy and safety of rosuvastatin initiation with those of switching of ritonavir-boosted protease inhibitors (PI/rs) in HIV-1-infected adults with hypercholesterolaemia and increased cardiovascular risk scores. METHODS In this open-label, multicentre study, HIV-1-infected adults on PI/r-based therapy with viral load < 50 HIV-1 RNA copies/mL, fasting total cholesterol ≥ 5.5 mmol/L (both for ≥ 6 months) and elevated cardiovascular risk (Framingham score ≥ 8% or diabetes or family history), and not on lipid-lowering therapy, were randomized to open-label rosuvastatin 10 mg/day or to PI/r switching, both with standardized diet/exercise advice. The primary endpoint was change in total cholesterol at week 12 (intention to treat). RESULTS There were 43 participants (23 on rosuvastatin). Baseline characteristics were: mean [± standard deviation (SD)] age 55 (8.5) years, 42 (98%) male, 41 (95%) white race, and mean (± SD) total cholesterol 6.2 (1.2) mmol/L. At enrolment, PI/rs were lopinavir/ritonavir (n = 22; 51%), atazanavir/ritonavir (n = 12; 28%) and darunavir/ritonavir (n = 9; 21%). The commonest PI/r substitutes were raltegravir (n = 9; 45%) and rilpivirine (n = 4; 20%). All participants were adherent through to week 12. Rosuvastatin yielded greater declines than PI/r switching in total (- 21.4% vs. - 8.7%, respectively; P = 0.003) and low-density lipoprotein (- 29.9% vs. - 1.0%, respectively; P < 0.001) cholesterol, but smaller declines in very low-density lipoprotein cholesterol and triglycerides (P < 0.01). Cholesterol lowering was greater in participants on atazanavir/ritonavir or once-daily darunavir/ritonavir (vs. lopinavir/ritonavir). More study drug-related adverse events (mostly grade 1 nausea/diarrhoea; 10 vs. one, respectively; P = 0.001) occurred with PI/r switching than with rosuvastatin. CONCLUSIONS In adults receiving a PI/r, rosuvastatin 10 mg/day for 12 weeks yielded larger decreases in total and low-density lipoprotein cholesterol than PI/r switching, and was better tolerated.

Abstract
The introduction of potent combination antiretroviral therapy (cART) has had a remarkable impact on the natural history of HIV infection, leading to a dramatic decline in the mortality rate and a considerable increase in the life expectancy of HIV-positive people. However, cART use is frequently associated with several metabolic complications, mostly represented by lipid metabolism alterations, which are reported very frequently among persons treated with antiretroviral agents. In particular, hyperlipidaemia occurs in up to 70%-80% of HIV-positive subjects receiving cART and is mainly associated with specific antiretroviral drugs belonging to three classes of antiretroviral agents: NRTIs, NNRTIs and PIs. The potential long-term consequences of cART-associated dyslipidaemia are not completely understood, but an increased risk of premature coronary heart disease has been reported in HIV-infected patients on cART, so prompt correction of lipid metabolism abnormalities is mandatory in this population. Dietary changes, regular aerobic exercise and switching to a different antiretroviral regimen associated with a more favourable metabolic profile are the first steps in clinical management, but lipid-lowering therapy with fibrates or statins is often required. In this case, the choice of hypolipidaemic drugs should take into account the potential pharmacokinetic interactions with many antiretroviral agents.

Naringin Reverses Hepatocyte Apoptosis and Oxidative Stress Associated with HIV-1 Nucleotide Reverse Transcriptase Inhibitors-Induced Metabolic Complications. Nutrients 2015; 7:10352-68. [PMID: 26690471 PMCID: PMC4690092 DOI: 10.3390/nu7125540] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2015] [Revised: 10/02/2015] [Accepted: 10/13/2015] [Indexed: 12/17/2022] Open
Abstract
Nucleoside Reverse Transcriptase Inhibitors (NRTIs) have not only improved therapeutic outcomes in the treatment of HIV infection but have also led to an increase in associated metabolic complications of NRTIs. Naringin’s effects in mitigating NRTI-induced complications were investigated in this study. Wistar rats, randomly allotted into seven groups (n = 7) were orally treated daily for 56 days with 100 mg/kg zidovudine (AZT) (groups I, II III), 50 mg/kg stavudine (d4T) (groups IV, V, VI) and 3 mL/kg of distilled water (group VII). Additionally, rats in groups II and V were similarly treated with 50 mg/kg naringin, while groups III and VI were treated with 45 mg/kg vitamin E. AZT or d4T treatment significantly reduced body weight and plasma high density lipoprotein concentrations but increased liver weights, plasma triglycerides and total cholesterol compared to controls, respectively. Furthermore, AZT or d4T treatment significantly increased oxidative stress, adiposity index and expression of Bax protein, but reduced Bcl-2 protein expression compared to controls, respectively. However, either naringin or vitamin E significantly mitigated AZT- or d4T-induced weight loss, dyslipidemia, oxidative stress and hepatocyte apoptosis compared to AZT- or d4T-only treated rats. Our results suggest that naringin reverses metabolic complications associated with NRTIs by ameliorating oxidative stress and apoptosis. This implies that naringin supplements could mitigate lipodystrophy and dyslipidemia associated with NRTI therapy.

Abstract
For human immunodeficiency virus (HIV)-infected patients, the 1990s were marked by the introduction of highly active antiretroviral therapy (HAART) representing a new perspective of life for these patients. The use of HAART was shown to effectively suppress the replication of HIV-1 and dramatically reduce mortality and morbidity, which led to a better and longer quality of life for HIV-1-infected patients. Apart from the substantial benefits that result from the use of various HAART regimens, laboratory and clinical experience has shown that HAART can induce severe and considerable adverse effects related to metabolic complications of lipid metabolism, characterized by signs of lipodystrophy, insulin resistance, central adiposity, dyslipidemia, increased risk of cardiovascular disease and even an increased risk of atherosclerosis. New drugs are being studied, new therapeutic strategies are being implemented, and the use of statins, fibrates, and inhibitors of intestinal cholesterol absorption have been effective alternatives. Changes in diet and lifestyle have also shown satisfactory results.

Abstract
PURPOSE Antiretroviral therapy (ART) may induce metabolic changes and increase the risk of coronary heart disease (CHD). Based on a health care system approach, we investigated predictors for normalization of dyslipidemia in HIV-infected individuals receiving ART. METHOD Individuals included in the study were registered in the Swiss HIV Cohort Study (SHCS), had dyslipidemia but were not on lipid-lowering medication, were on potent ART for >or= 3 months, and had >or= 2 follow-up visits. Dyslipidemia was defined as two consecutive total cholesterol (TC) values above recommended levels. Predictors of achieving treatment goals for TC were assessed using Cox models. RESULTS Analysis included 958 individuals with median followup of 2.3 years (IQR 1.2-4.0). 454 patients (47.4%) achieved TC treatment goals. In adjusted analyses, variables significantly associated with a lower hazard of reaching TC treatment goals were as follows: older age (compared to 18-37 year olds: hazard ratio [HR] 0.62 for 45-52 year olds, 95% CI 0.47-0.82; HR 0.40 for 53-85, 95% CI 0.29-0.54), diabetes (HR 0.39, 95% CI 0.26-0.59), history of coronary heart disease (HR 0.27, 95% CI 0.10-0.71), higher baseline TC (HR 0.78, 95% CI 0.71-0.85), baseline triple nucleoside regimen (HR 0.12 compared to PI-only regimen, 95% CI 0.07-0.21), longer time on PI-only regimen (HR 0.39, 95% CI 0.33-0.46), longer time on NNRTI only regimen (HR 0.35, 95% CI 0.29-0.43), and longer time on PI/NNRTI regimen (HR 0.34, 95% CI 0.26-0.43). Switching ART regimen when viral load was undetectable was associated with a higher hazard of reaching TC treatment goals (HR 1.48, 95% CI 1.14-1.91). CONCLUSION In SHCS participants on ART, several ART-related and not ART-related epidemiological factors were associated with insufficient control of dyslipidemia. Control of dyslipidemia in ART recipients must be further improved.

Abstract
AIMS With the success of antiretroviral therapy (ART), non-human immunodeficiency virus (HIV)-related comorbidities like cardiovascular diseases (CVDs) are of increasing concern. We describe important recent research developments on the epidemiology of CVD in HIV infection, ART-related metabolic changes, and cardioprotective anti-inflammatory mechanisms, and summarize management strategies for CVD risk reduction. METHODS AND RESULTS We systematically identified and analysed systematic reviews and most cited literature published in the last 3 years and supplemented findings with selected evidence based on clinical expertise. Among HIV-infected individuals, the prevalence of CVD risk factors and the risk for CVD is higher compared with HIV negatives. Antiretroviral drugs may induce dyslipidaemia, reduce insulin sensitivity, and promote body fat redistribution that additionally contributes to CVD risk. Some antiretroviral drugs may increase risk for CVD events, but the absolute risk increase is moderate and has to be put into perspective with the massive HIV-related benefits. Sustained HIV suppression reduces systemic inflammatory markers and is associated with a moderate reduction in CVD events. Regular CVD risk assessment and counselling to stop smoking must be regularly done in all HIV-infected individuals. Statins are effective for the treatment of dyslipidaemia in HIV infection, but drug interactions with ART need to be considered. CONCLUSION Human immunodeficiency virus-infected individuals are at increased risk for CVD. Timely initiation of ART with consequent viral suppression is likely to reduce CVD events and to offset potential side effects from ART-induced metabolic changes. Reduction in smoking in HIV-infected individuals is a public health priority.

Abstract
BACKGROUND Statins are lipid-lowering drugs that exhibit anti-inflammatory and immune-modulatory properties, leading to a reduction of serum levels of C-reactive protein (CRP) in the general population. OBJECTIVE Because very limited data are available today, our objective was to assess the lipid-lowering effects of statins and their capacity to decrease selected soluble markers of inflammation in HIV-infected patients. METHODS Retrospective cohort study of HIV-infected adult patients with hypercholesterolemia who were receiving a stable antiretroviral regimen including a ritonavir-boosted protease inhibitor and who started a lipid-lowering therapy with rosuvastatin (10 mg daily), atorvastatin (10 mg daily), or pravastatin (40 mg daily) and were followed-up for at least 12 months. One hundred and fifty-one patients were enrolled in the study: 51 in the rosuvastatin group, 47 in the atorvastatin group, and 53 in the pravastatin group. The primary observation was change in plasma lipid levels and serum markers of inflammation (high-sensitivity C-reactive protein [hsCRP], interleukin-6 [IL-6], and tumor necrosis factor-α [TNF- α]), while secondary observations include immunovirological parameters and safety profile of statins. RESULTS One year after starting the statin therapy, patients treated with rosuvastatin had significantly greater decreases in total cholesterol and LDL cholesterol than subjects on atorvastatin or pravastatin. All statins led to a similar, significant reduction in serum levels of hsCRP and TNF-α, without correlation between biomarkers and lipid values, and toxicity rates were similar for all 3 statins. CONCLUSION Our findings suggest that rosuvastatin has a significantly greater lipid-lowering effect than atorvastatin or pravastatin, but all 3 statins exert a similar effect in lowering markers of inflammation as hsCRP and TNF-α.

Abstract
Human immunodeficiency virus (HIV) infection is strongly associated with ischemic stroke in the young. Data obtained from the Nationwide Inpatient Sample in the United States show an increase in the number of stroke hospitalizations in the HIV-infected population despite an overall decrease in the number of stroke hospitalizations. Few data exist, however, that address the mechanism of HIV-associated stroke. Recent studies have demonstrated that HIV may infect the endothelium and alter cerebrovascular functions. Whether the proposed mechanism alters the stroke risk is undetermined. Epidemiological studies suggest that HIV-related stroke is associated with a risk factor profile that differs from the HIV-negative young stroke population in that HIV-associated strokes are less likely to have hypertension, diabetes, hyperlipidemia and smoking as risk factors. A large population-based study, moreover, suggests an association between antiretroviral therapy and increased cardio- and cerebrovascular risks. Specific antiretroviral agents such as protease inhibitors and non-nucleoside reverse transcriptase inhibitors have been implicated in the metabolic syndrome, accelerated atherosclerosis and an increased risk for ischemic stroke. In addition to discussing these developments, this paper also discusses the implications of recent data for stroke prevention in HIV-infected patients.

Abstract
BACKGROUND Morphological abnormalities (lipoatrophy and central fat accumulation) and metabolic changes (dyslipidaemia and glucose regulation impairment) have emerged as components of lipodystrophy and as major tolerability issues with long-term use of highly active antiretroviral therapy (HAART) in HIV-positive patients. Protease inhibitors (PIs) are recognized as having the greatest impact in terms of metabolic complications, followed by nucleoside reverse transcriptase inhibitors, while the non-nucleoside reverse transcriptase inhibitors (NNRTIs) have the least impact. In particular, regimens based on the NNRTI nevirapine have been shown to achieve significant metabolic benefits and may help to improve dyslipidaemia. Improvements in body shape changes associated with lipodystrophy have also been reported when nevirapine replaced a PI in long-term triple therapy. OBJECTIVE The objective of this cross-sectional observational ('real-world') study was to investigate the effect of three HAART regimens plus stable nevirapine therapy on morphological and metabolic components of lipodystrophy in HIV-infected patients. METHODS Consecutive patients (aged >18 years) with serologically documented HIV infection, who had received HAART for at least 2 years and who had been diagnosed with lipodystrophy, were followed up as outpatients at the metabolic clinic of the University of Modena and Reggio Emilia, Modena, Italy. Patients received stable nevirapine therapy plus fixed-dose combinations of tenofovir disoproxil fumarate plus emtricitabine (Truvada(®); TVD), zidovudine plus lamivudine (3TC) [Combivir(®); CBV], or abacavir plus lamivudine (Kivexa(®); KVX). Multivariate regression analyses were performed to analyse predictors of four components of lipodystrophy: lipoatrophy using leg fat mass measured by dual-emission x-ray absorptiometry (DXA), fat accumulation using waist circumference, dyslipidaemia using apolipoprotein (Apo)B/ApoA1 ratio, and glucose intolerance using the Homeostasis Model Assessment for Insulin Resistance (HOMA-IR). RESULTS Overall, 101 patients were enrolled (TVD group = 61, CBV group = 20, KVX group = 20); 191 observations were analysed. Male sex was associated with reduced leg fat mass, while age and body mass index (BMI) were associated with increased leg fat mass (all p < 0.05). Leg fat mass and male sex were associated with increased waist circumference (p < 0.001 for both). Leg fat mass predicted reduced ApoB/ApoA1 ratio, while age and BMI predicted increased ApoB/ApoA1 ratio (all p < 0.05). BMI predicted HOMA-IR increase (p = 0.0017). No differences in lipoatrophy, central fat accumulation, dyslipidaemia or glucose metabolism were observed among any of the three different nevirapine plus nucleoside backbone groups (TVD, CBV or KVX). CONCLUSION HAART including nevirapine has a limited impact on components of lipodystrophy in patients with HIV infection. Further studies are needed to verify if nevirapine overcomes the expected distinct lipodystrophy risk profile associated with different nucleoside backbone therapies.

Abstract
BACKGROUND We investigated the effects of individual antiretrovirals on lipids in HIV-infected children and the proportion potentially eligible for dietary or pharmacologic intervention. METHODS St Mary's and Great Ormond Street Hospital's, London, United Kingdom, patients between 1995 and 2007 were included. Associations between lipids (millimoles per liter) and specific antiretroviral therapy were assessed using mixed-effects models adjusted for confounders. Children eligible for lipid-lowering management were assessed according to American Academy of Pediatric criteria [low-density lipoprotein (LDL) > 190 mg/dL or 4.9 mmol/L for children with no known cardiovascular disease risk factors or LDL > 160 mg/dL or 4.1 mmol/L for children with 2 or more cardiovascular disease risk factors]. RESULTS Four hundred forty-nine children had median 4.5-year follow-up. On average, antiretroviral therapy-naive children had normal lipids except for low high-density lipoprotein cholesterol (HDL) (median 0.8). All cholesterol subsets were elevated for the 4 drugs assessed. Protease inhibitors had greater rises in total cholesterol with the maximal non-HDL rise for lopinavir/ritonavir at 4+ years of exposure, 0.8 (0.57-1.03). The nonnucleoside reverse transcriptase inhibitors also raised non-HDL, but this was associated with additional clinically significant increases in HDL. Nevirapine raised non-HDL by 0.38 (0.09-0.31) at 2-3 years and HDL by 0.34 (0.28-0.41). Efavirenz raised non-HDL by 0.2 (0.09-0.31) and HDL by 0.12 (0.08-0.17) at 1 year. Ten percent had LDL above the 95th percentile, but only 3 met the 4.9 cutoff for pharmacologic intervention. CONCLUSIONS Intervention strategies (dietary and exercise advice, treatment switching, and pharmacotherapy) are required for persistent hyperlipidemia and should be assessed in randomized control trials.

Abstract
Metabolic complications continue to play a major role in the management of HIV infection. Dyslipidemia associated with HIV infection and with the use of combined antiretroviral therapy includes elevations in triglycerides, reduced high-density cholesterol, and variable increases in low-density and total cholesterol. The association between dyslipidemia and specific antiretroviral agents has been underscored. Multiple pathogenic mechanisms by which HIV and antiretroviral agents lead to dyslipidemia have been hypothesized, but they are still controversial. The potential clinical and pathological consequences of HIV-associated hyperlipidemia are not completely known, but several studies reported an increased risk of coronary artery disease in HIV-positive individuals receiving combined antiretroviral therapy. HIV-infected persons who have hyperlipidemia should be managed similarly to those without HIV infection in accordance with the National Cholesterol Education Program. Life style changes are the primary target. Statins and fibrates and/or modification in antiretroviral therapy are possible approaches to this problem.

Abstract
Morphologic and metabolic abnormalities, including subcutaneous adipose tissue wasting, central adipose tissue accumulation, dyslipidemia and disorders of glucose metabolism are common among HIV-infected patients receiving highly active antiretroviral therapy (HAART) and contribute to the risk of cardiovascular disease in this population. The pathogenesis of these disorders is due to complicated interactions between effects of chronic HIV infection, HAART medications and patient factors, including genetic susceptibility. HAART has transformed HIV into a chronic condition for many patients and as a result the majority of HIV-infected patients in many areas of the developed world will soon be aged ≥50 years. Given that metabolic and cardiovascular diseases increase with aging, knowledge of the optimal management of these conditions is essential for practitioners caring for HIV-infected patients, including endocrine subspecialists. This Review highlights the clinical management of these disorders, focusing on the latest evidence regarding the efficacy of treatment strategies, newly available medications and potential interactions between HAART medications and medications used to treat metabolic disorders.

Abstract
Antiretroviral therapy has dramatically increased survival for HIV-infected individuals. As this population lives longer, coronary heart disease has become an important comorbid condition. Dyslipidemia in HIV-infected individuals is a complex condition, with multiple contributing factors including the HIV virus itself, individual genetic characteristics and antiretroviral therapy-induced metabolic changes. Effective management of dyslipidemia in this population is essential to reduce cardiovascular risk but presents multiple challenges due to interactions between antiretroviral therapy agents and lipid-lowering medications.

Abstract
Over 30 million people are currently living with human immunodeficiency virus (HIV) infection, and over 2 million new infections occur per year. HIV has been found to directly affect vascular biology resulting in an increased risk of cardiovascular disease compared to uninfected persons. Although HIV infection can now be treated effectively with combination antiretroviral medications, significant toxicities such as hyperlipidemia, diabetes, and excess cardiovascular co-morbidity; as well as the potential for significant drug-drug interactions between HIV and cardiovascular medications, present new challenges for the management of persons infected with HIV. We first review basic principles of HIV pathogenesis and treatment and then discuss relevant clinical management strategies that will be useful for cardiologists who might be involved in the care of HIV infected patients.

Abstract
Insulin resistance (IR) was one of the first metabolic complications reported with highly active antiretroviral therapy for HIV infection. It continues to be of concern despite the introduction of newer antiretrovirals with safer metabolic profiles and is associated with inflammation and the development of diabetes mellitus. As the HIV-infected population ages, the prevalence of IR is likely to rise. Specific antiretrovirals can increase insulin resistance through two principal mechanisms, either directly by interfering with insulin signalling at the cellular level or indirectly as a consequence of defects in lipid metabolism (lipotoxocity) arising from antiretroviral toxicities such as the IR observed in those with HIV-associated lipodystrophy. There is considerable overlap between different antiretrovirals in their propensity to cause IR making it more difficult to attribute development of IR to a particular antiretroviral medication. In addition, in the setting of a generalised epidemic of obesity that exists in many populations worldwide, HIV-infected patients may be more prone to the consequences of antiretroviral-induced insulin resistance and diabetes mellitus. Optimal screening and treatment strategies for IR in treated HIV infection have not been established. In this article we review current opinion on insulin resistance in HIV and identify potential areas for future research.

Abstract
INTRODUCTION Nevirapine (NVP), a non-nucleoside reverse transcriptase inhibitor, has been an important component of HIV infection treatment for many years. Currently, twice-a-day dosing is required for the successful application of NVP immediate release (IR), but there is potential for a more convenient once-a-day antiretroviral combination. AREAS COVERED The purpose of this article is to review the recent data on once-daily NVP extended release (XR) looking at all the important pharmacologic, pharmacokinetic and clinical data on NVP IR/XR through a systematic MEDLINE database search as well as a review of abstracts presented at international HIV meetings on NVP XR studies up to December 2010. The article provides the reader with an overview of all the pharmacodynamic and pharmacokinetic aspects of NVP IR/XR, as well as its preclinical and clinical efficacy and its safety. EXPERT OPINION NVP XR is as effective as NVP IR among HIV-infected patients with a similar safety profile. NVP XR requires careful monitoring during initiation, but its favorable lipid profile may be of clinical benefit in reducing the risk for coronary artery disease in HIV-infected patients who are receiving long-term antiretroviral therapy. Further research is needed to predict short-term toxicity.

Abstract
HIV-infected patients are living decades longer than before owing to combination antiretroviral therapy. However, complications are emerging in this population at rates higher than the general population, including cardiovascular disease (CVD). HIV-infected patients have many traditional risk factors that account for a significant part of their increased risk of CVD. However, HIV factors, including complications from antiretroviral therapy and increased inflammation associated with chronic HIV infection, also play a role. Clinicians need to be ever-vigilant to calculate and help attenuate any modifiable CVD risk factors for each HIV-infected individual.

Abstract
Effective highly active antiretroviral therapy (HAART) for human immunodeficiency virus-1 (HIV) infection has led to marked improvement in life-expectancy for those infected with HIV. Despite reductions in the incidence of AIDS with effective treatment, patients continue to experience considerable morbidity and mortality from non-AIDS illness such as premature cardiovascular disease, liver failure and renal failure. These morbidities, particularly premature cardiovascular disease, are thought to be related to a combination of the effects of an ageing HIV-infected population coupled with long-term effects of HIV infection and antiretroviral therapy (ART). One of the principle drivers behind the well documented increase in the risk of cardiovascular disease in HIV-infected patients is dyslipidemia. This review will focus on the clinical presentation of HIV and ART-associated dyslipidemia, what is known of its patho-physiology, including associations with use of specific antiretroviral medications, and suggest screening and management strategies.

Abstract
Switching antiretroviral therapy has been shown as safe and effective, but its impact on health-related quality of life (HRQL) was rarely measured. Our objective was to assess changes in HRQL after switching to an non-nucleoside reverse transcriptase inhibitors (NNRTI) containing regimen among NNRTI-naive HIV-infected patients with viral load (VL) <500 copies/mL. In this prospective observational study, the Hospital Anxiety and Depression, Symptoms checklist, specific World Health Organization Quality of Life (WHOQoL) and generic SF-12v2 HRQL questionnaires were used to assess anxiety, depression, symptoms, and HRQL at baseline and months 1 (M1), 6 (M6), and 12 (M12). The statistical significance of changes in the frequency of anxiety and depression was determined with the McNemar test. Mean changes in the number of symptoms and in HRQL scores were compared using Wilcoxon's paired test. Data were available for 239 patients at baseline (162 with a switch to nevirapine) and for 164 patients at M6. The median age of the patients was 42 years and 67% of patients were male. The proportion of anxious patients diminished at M6 (11%, P=0.02) but not yet at M1. There was no change in the frequency of depression. Significant reductions (p<0.01) were observed at M6 in the mean number of all symptoms (-3.3), lipodystrophy symptoms (-0.8), other symptoms (-2.5), bothersome symptoms (-1.7), bothersome lipodystrophy symptoms (-0.4), and bothersome other symptoms (-1.3). HRQL as assessed with WHOQoL, improved in the physical, independence, and spirituality domains, with a small effect sizes at M6. Both for symptoms and HRQL, these changes were already significant at M1 and persisted at M12. This study shows that in patients with controlled VL, switching to an NNRTI regimen was associated with less anxiety, fewer perceived symptoms, and a small improvement in HRQL, while maintaining virological suppression.

Abstract
Cardiovascular diseases are an increasing problem in patients with HIV infection. The causes of the increased cardiovascular risk in HIV-infected patients are multifactorial. Currently, the question of which factor has the most weight in this equation - whether traditional risk factors, the virus per se or antiretroviral therapy - remains to be determined. The absolute risk of cardiovascular disease in a particular patient depends on the composite risk profile. At present, there are no data to support a distinct approach to cardiovascular risk evaluation in HIV-infected patients. Cardiovascular risk equations should be incorporated into routine daily clinical assessment in order to identify patients in need of specific interventions.

Abstract
Atazanavir (Reyataz), a protease inhibitor (PI), is approved in many countries for use as a component of antiretroviral therapy (ART) regimens for the treatment of adult, and in some countries in paediatric, patients with HIV-1 infection. ART regimens containing ritonavir-boosted atazanavir improved virological and immunological markers in adult patients with HIV-1 infection, and had similar efficacy to regimens containing lopinavir/ritonavir in treatment-naive and treatment-experienced patients. In addition, unboosted atazanavir was noninferior to ritonavir-boosted atazanavir in treatment-naive patients. Atazanavir is administered once daily and has a low capsule burden. Atazanavir, whether unboosted or boosted, was generally well tolerated and appeared to be associated with less marked metabolic effects, including less alteration of lipid levels, than other PIs. These properties mean that boosted atazanavir, and unboosted atazanavir in patients unable to tolerate ritonavir, continues to have a role as a component of ART regimens in patients with HIV-1 infection.

Abstract
Antiretroviral therapy (ART) is an effective strategy for preventing disease progression of HIV infection, particularly when patients adhere closely to the treatment regimen. However, ART medications can cause side effects, including metabolic complications that can impact patients' adherence levels. Selected chronic complications associated with ART include lipodystrophy, hyperlipidemia, insulin resistance and diabetes, peripheral neuropathy, and bone disorders such as osteopenia/osteoporosis. In this article, we review the effects of these metabolic complications on ART adherence and approaches to prevent or reverse them.

Abstract
Evidence-based guidelines for the management of persons infected with human immunodeficiency virus (HIV) were prepared by an expert panel of the HIV Medicine Association of the Infectious Diseases Society of America. These updated guidelines replace those published in 2004. The guidelines are intended for use by health care providers who care for HIV-infected patients or patients who may be at risk for acquiring HIV infection. Since 2004, new antiretroviral drugs and classes have become available, and the prognosis of persons with HIV infection continues to improve. However, with fewer complications and increased survival, HIV-infected persons are increasingly developing common health problems that also affect the general population. Some of these conditions may be related to HIV infection itself and its treatment. HIV-infected persons should be managed and monitored for all relevant age- and gender-specific health problems. New information based on publications from the period 2003–2008 has been incorporated into this document.

Abstract
OBJECTIVES The influence on the progression of atherosclerosis of an intervention on cardiovascular risk factors in HIV-infected patients remains unknown. We evaluated the efficacy and safety of an intensive versus a standard intervention in HIV-infected patients with moderate-high cardiovascular risk. METHODS A pilot randomized clinical trial. Stable HIV-infected patients with viral suppression on antiretroviral therapy, and two or more cardiovascular risk factors or a Framingham risk score >or=10%. An intensive intervention targeting low-density lipoprotein (LDL)-cholesterol <100 mg/dl, using antiplatelet therapy, and switching protease inhibitor (PI) therapy, was compared with the standard intervention aiming for LDL-cholesterol <130 mg/dL. The primary endpoint was progression of atherosclerosis measured by the carotid intima-media thickness (cIMT). Secondary endpoints were efficacy in achieving the LDL-cholesterol goal, changes in inflammatory biomarkers, and feasibility and safety of the intervention. RESULTS Thirty-two (47%) and 36 (53%) patients were assigned to the intensive and the standard interventions, respectively. After 12 months, the median proportion of change in the cIMT was +1.63% (-4.95 to +10.54) in the intensive intervention, and +1.79% (-6.61 to +6.1) in the standard group (P = 0.59). LDL-cholesterol (39% versus 7%, P < 0.001) and Framingham score (10% versus 0%, P = 0.03) showed larger reductions in the intensive group. No significant changes in levels of C-reactive protein, interleukin-6 and tumour necrosis factor-alpha were found. No significant adverse events were reported and no virological failures occurred during the study. CONCLUSIONS An aggressive intervention targeting LDL-cholesterol in HIV-infected patients was safe and capable of attaining very stringent target levels in adherent patients. However, the intervention did not influence cIMT progression or inflammatory biomarkers after 1 year of follow-up.

Abstract
Highly active antiretroviral therapy (HAART) has significantly improved the prognosis for many individuals with HIV infection. Consequently, HIV infection has become a chronic and manageable disease. The focus on long-term management of patients with HIV infection has broadened to include comorbid conditions, most notably cardiovascular disease. Patients with HIV infection share many cardiovascular risk factors with the general population, and HIV infection itself may increase cardiovascular risk. Changes in lipid profiles associated with increased cardiovascular risk that have been observed with some HAART regimens have been a cause for concern among clinicians who treat HIV-infected patients. However, the lipid effects of HAART seem to depend on the type and duration of regimens employed. They can be managed effectively according to current guidelines that recommend lifestyle changes (eg, improved diet, increased exercise, smoking cessation) and pharmacologic therapy described in established treatment paradigms for patients on antiretroviral therapy and similar to measures currently used by the general population. A review of the clinical data indicates that the virologic and immunologic benefits of HAART clearly outweigh any metabolic effects observed in some patients over time and that preexisting, established cardiovascular risk factors contribute significantly to the potential development of cardiovascular events. These benefits of antiretroviral therapy have been demonstrated in studies comparing the superior efficacy of continuous vs. intermittent HAART.

Abstract
Dyslipidemia now is recognized as a significant potential adverse event in HIV-infected patients who are receiving antiretroviral therapy. HIV-infected persons who have hyperlipidemia should be managed similarly to those without HIV infection in accordance with the National Cholesterol Education Program. Providers must treat the HIV infection first; if dyslipidemia develops, patients should be prescribed lipid-lowering therapies or should consider modifying their current antiretroviral therapy, if indicated. Evidence for these two strategies is discussed.

Abstract
It has been demonstrated that patients on highly active antiretroviral therapy are at increased risk for developing metabolic abnormalities that include elevated levels of serum triglycerides and low-density lipoprotein cholesterol and reduced levels of high-density lipoprotein cholesterol. This dyslipidemia is similar to that seen in the metabolic syndrome, raising the concern that highly active antiretroviral therapy also potentially increases the risk for cardiovascular complications. This paper reviews the contribution of both HIV infection and the different components of highly active antiretroviral therapy to dyslipidemia and the role of these abnormalities toward increasing the risk of cardiovascular disease in HIV-infected patients; therapeutic strategies to manage these risks are also considered.

Abstract
BACKGROUND Because of the known relationship between exposure to combination antiretroviral therapy and cardiovascular disease (CVD), it has become increasingly important to intervene against risk of CVD in human immunodeficiency virus (HIV)-infected patients. We evaluated changes in risk factors for CVD and the use of lipid-lowering therapy in HIV-infected individuals and assessed the impact of any changes on the incidence of myocardial infarction. METHODS The Data Collection on Adverse Events of Anti-HIV Drugs Study is a collaboration of 11 cohorts of HIV-infected patients that included follow-up for 33,389 HIV-infected patients from December 1999 through February 2006. RESULTS The proportion of patients at high risk of CVD increased from 35.3% during 1999-2000 to 41.3% during 2005-2006. Of 28,985 patients, 2801 (9.7%) initiated lipid-lowering therapy; initiation of lipid-lowering therapy was more common for those with abnormal lipid values and those with traditional risk factors for CVD (male sex, older age, higher body mass index [calculated as the weight in kilograms divided by the square of the height in meters], family and personal history of CVD, and diabetes mellitus). After controlling for these, use of lipid-lowering drugs became relatively less common over time. The incidence of myocardial infarction (0.32 cases per 100 person-years [PY]; 95% confidence interval [CI], 0.29-0.35 cases per 100 PY) appeared to remain stable. However, after controlling for changes in risk factors for CVD, the rate decreased over time (relative rate in 2003 [compared with 1999-2000], 0.73 cases per 100 PY [95% CI, 0.50-1.05 cases per 100 PY]; in 2004, 0.64 cases per 100 PY [95% CI, 0.44-0.94 cases per 100 PY]; in 2005-2006, 0.36 cases per 100 PY [95% CI, 0.24-0.56 cases per 100 PY]). Further adjustment for lipid levels attenuated the relative rates towards unity (relative rate in 2003 [compared with 1999-2000], 1.06 cases per 100 PY [95% CI, 0.63-1.77 cases per 100 PY]; in 2004, 1.02 cases per 100 PY [95% CI, 0.61-1.71 cases per 100 PY]; in 2005-2006, 0.63 cases per 100 PY [95% CI, 0.36-1.09 cases per 100 PY]). CONCLUSIONS Although the CVD risk profile among patients in the Data Collection on Adverse Events of Anti-HIV Drugs Study has decreased since 1999, rates have remained relatively stable, possibly as a result of a more aggressive approach towards managing the risk of CVD.
