Abstract
Objectives: Cardiovascular disease has become one of the most common comorbidities among HIV-infected patients, but available data about the correlation between antiretroviral drugs and progression rate of atherosclerotic disease are still limited. We evaluated the progression rate of carotid atherosclerosis in patients starting an initial antiretroviral regimen including one integrase strand transfer inhibitor (INSTI).Methods: Observational, prospective study involving HIV-1-infected, antiretroviral therapy-naive, adult patients who started an antiretroviral regimen including tenofovir alafenamide/emtricitabine (TAF/FTC) plus raltegravir (RAL group), elvitegravir/cobicistat (EVG/c group), or dolutegravir (DTG group). Patients with known cardiovascular disease or diabetes mellitus were excluded from the study. The progression rate of atherosclerosis has been assessed by carotid Doppler ultrasonography at baseline and after 24 months.Results: Overall, 102 patients were enrolled into the study: 73 males, with mean age of 48.7 years: 32, 36 and 34 patients were included in the RAL, EVG/c and DTG groups, respectively. The baseline features of the enrolled patients were comparable across the three groups. At 24 months, the mean intima-media thickness (IMT) increase at the carotid bifurcation was 0.026 mm in the RAL group, 0.029 mm in EVG/c group and 0.032 mm in DTG group. The mean IMT increases after 24 months were comparable across the three groups and statistically not significant in all the evaluated anatomical sites.Conclusions: The initial antiretroviral therapy with TAF/FTC plus RAL, EVG/c or DTG for 24 months led to a comparable and not significant effect on the progression rate of carotid atherosclerosis.

Abstract
In many, but not all studies, people living with HIV (PLWH) have an increased risk of coronary artery disease (CAD) events compared to the general population. This has generated considerable interest in the early, non-invasive detection of asymptomatic (subclinical) atherosclerosis in PLWH. Ultrasound studies assessing carotid artery intima-media thickness (CIMT) have tended to show a somewhat greater thickness in HIV+ compared to HIV−, likely due to an increased prevalence of cardiovascular (CV) risk factors in PLWH. Coronary artery calcification (CAC) determination by non-contrast computed tomography (CT) seems promising to predict CV events but is limited to the detection of calcified plaque. Coronary CT angiography (CCTA) detects calcified and non-calcified plaque and predicts CAD better than either CAC or CIMT. A normal CCTA predicts survival free of CV events over a very long time-span. Research imaging techniques, including black-blood magnetic resonance imaging of the vessel wall and 18F-fluorodeoxyglucose positron emission tomography for the assessment of arterial inflammation have provided insights into the prevalence of HIV-vasculopathy and associated risk factors, but their clinical applicability remains limited. Therefore, CCTA currently appears as the most promising cardiac imaging modality in PLWH for the evaluation of suspected CAD, particularly in patients <50 years, in whom most atherosclerotic coronary lesions are non-calcified.

Abstract
Background AIDS as well as atherosclerosis are important public health problems. The
longer survival among HIV-infected is associated with increased number of
cardiovascular events in this population, and this association is not fully
understood. Objectives To identify the frequency of subclinical atherosclerosis in HIV-infected
patients compared to control subjects; to analyze associations between
atherosclerosis and clinical and laboratory variables, cardiovascular risk
factors, and the Framingham coronary heart disease risk score (FCRS). Methods Prospective cross-sectional case-control study assessing the presence of
subclinical atherosclerosis in 264 HIV-infected patients and 279 controls.
Clinical evaluation included ultrasound examination of the carotid arteries,
arterial stiffness by pulse wave velocity (PWV) and augmentation index
(AIx), laboratory analysis of peripheral blood, and cardiovascular risk
according to FCRS criteria. The significance level adopted in the
statistical analysis was p < 0.05. Results Plaques were found in 37% of the HIV group and 4% of controls (p < 0.001).
Furthermore, carotid intima-media thickness was higher in the HIV group than
in controls (p < 0.001). Patients with carotid plaque had higher fasting
glucose, total cholesterol, low-density lipoprotein cholesterol, and
triglycerides than those without plaques. The presence of HIV, adjusted for
age, overweight/obesity, and smoking increased by almost fivefold the risk
of atherosclerotic carotid plaque (OR: 4.9; 95%CI: 2.5-9.9; p < 0.001).
Exposure to protease inhibitors did not influence carotid intima-media
thickness, was not associated with carotid plaque frequency, and did not
alter the mechanical characteristics of the arterial system (PWV and
AIx). Conclusions HIV-infected patients are at increased risk of atherosclerosis in association
with classical cardiovascular risk factors. Treatment with protease
inhibitors does not promote functional changes in the arteries, and shows no
association with increased frequency of atherosclerotic plaques in carotid
arteries. The FCRS may be inappropriate for this population.

Abstract
Introduction Endothelium-dysfunction (ED) is a surrogate marker of coronary atherosclerotic disease. Carotid intima-media thickness (CIMT), flow-mediated dilatation (FMD), and proteinuria are surrogate markers of ED. Few studies have shown that patients with HIV have impaired endothelial function and are thus at risk of accelerated atherosclerosis. Materials and Methods The present study assessed ED in HIV patients by various biophysical parameters as brachial artery FMD, CIMT, and proteinuria. A total of 43 HIV-infected patients were compared with 25 healthy controls who were healthy. Results Mean age of patients with HIV was 33.84 ± 5.61 years while that of healthy controls was 31.48 ± 5.40 years. Male to female ratio among cases was 24:19 while among controls was 17:8. Mean CIMT was significantly higher among cases than control (0.513 ± 0.079, 0.452 ± 0.050 mm, respectively, P = 0.001). Percentage change in FMD was significantly lower among cases than control (3.27 ± 2.01, 6.96 ± 1.28, respectively, P = 0.001). Urine protein grading was significantly different between cases and controls (P = 0.007), with stable HIV cases having significantly higher urine protein grading compared to healthy controls. However, no correlation was seen between CIMT, FMD, and proteinuria overall among cases and controls. Conclusions HIV-infected patients have significant impairment of endothelial function, in the form of increased CIMT, impaired FMD, and more proteinuria as compared to healthy controls.

Abstract
BACKGROUND The prevalence of atherosclerosis is higher in HIV-positive people, who also experience it earlier than the general population. OBJECTIVES To assess and compare the prevalence of atherosclerosis evaluated by the intima-media thickness of carotid and femoral arteries, and by the ankle-brachial pressure index (ABPI) in HIV patients treated or not treated with protease inhibitors (PIs) and controls. METHODS Eighty HIV+ subjects (40 using PIs and 40 not using PIs) and 65 controls were included in the study. Atherosclerosis was diagnosed by (carotid and femoral) ITM measurement and ABPI. Classical risk factors for atherosclerosis and HIV were compared between the groups by statistical tests. A p ≤ 0.05 was considered significant. RESULTS An IMT > P75 or the presence of plaque was higher in the HIV+ than in the control group (37.5% vs 19%, p = 0.04). Comparative analysis showed a significant difference (p=0.014) in carotid IMT between HIV+ with PIs (0.71 ± 0.28 mm), without PIs 0.63 ± 0.11 mm and, and controls (0.59 ± 0.11 mm). There was no significant difference in femoral IMT between the groups or in ABPI between HIV+ subjects and controls. However, a significant difference (p=0.015) was found between HIV+ patients not treated with PIs (1.17 [1.08 - 1.23]), and controls 1.08 [1.07 - 1.17]). CONCLUSION In HIV patients, atherosclerosis is more prevalent and seems to occur earlier with particular characteristics compared with HIV-negative subjects.

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.

Abstract
OBJECTIVES HIV infection is associated with dyslipidaemia and increased risk of cardiovascular disease. The effects of HIV infection and antiretroviral treatment on surrogate markers of atherosclerosis, and lipoprotein metabolism were evaluated in a 12 month prospective study. METHODS AND RESULTS Treatment-naive HIV patients were recruited into one of three groups: untreated HIV infection not likely to require initiation of antiretroviral therapy (ART) for at least 12 months; initiating treatment with non nucleoside reverse transcriptase inhibitor-containing ART regimen and initiating treatment with protease inhibitor-containing ART regimen. The patients underwent assessment of carotid intima-media thickness (cIMT), pulse wave velocity (PWV), brachial flow-mediated dilation (FMD) and variables of plasma lipoprotein metabolism at baseline and 12 months. The findings were compared with published values for age and sex matched HIV-negative healthy subjects in a cross-sectional fashion. cIMT and FMD were lower while PWV was higher in HIV-patients compared with HIV-negative individuals; none of the markers changed significantly during 12 months follow up. HIV patients had hypoalphalipoproteinemia and elevated plasma levels of lecithin:cholesterol acyltransferase (LCAT) and cholesteryl ester transfer protein. The only significant changes in lipid-related variables were elevation of total cholesterol and triglycerides in patients treated with PI-containing regimen and elevation of plasma LCAT levels in patients treated with NNRTI-containing regimen. The ability of whole and apoB-depleted plasma to effect cholesterol efflux was not impaired in all three groups. CONCLUSIONS This study did not find evidence for rapid progression of subclinical atherosclerosis and deterioration of dyslipidaemia in HIV patients within 1 year.

Abstract
Recent studies have shown that rosuvastatin significantly decreases serum levels of inflammatory biomarkers and slows progression of carotid atherosclerosis in the general population. However, there are no data about its effect on progression of atherosclerosis in HIV-infected patients. Adult patients with HIV infection, on stable antiretroviral therapy, with asymptomatic carotid atherosclerosis and hypercholesterolemia, who started a rosuvastatin treatment at 10 mg daily during the period 2007-2009 were enrolled and followed-up for 24 months. Thirty-six patients (30 males) were enrolled, with a mean age of 49 years, a mean duration of current antiretroviral therapy of 38 months, and a mean 10-year risk of myocardial infarction of 18.5%. Rosuvastatin led to a significant decrease in mean values of intima-media thickness in all extracranial carotid arteries, with the greatest magnitude observed in carotid bifurcations (a mean decrease of 18.7% in the right artery and of 21.4% in the left artery) and in internal carotid arteries (a mean decrease of 23.7% in the right artery and of 25.6% in the left artery). Moreover, there was a significant reduction in mean levels of total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides versus respective baseline values associated with a significantly decreased mean cardiovascular risk. The treatment with rosuvastatin was well tolerated, and serious adverse events were not reported. A 24-month treatment with rosuvastatin in HIV-infected patients on highly active antiretroviral therapy (HAART) with subclinical atherosclerosis and a moderate cardiovascular risk seems to promote significantly favorable changes in carotid atherosclerosis, associated with a favorable effect on serum lipid levels and a good tolerability profile.

Abstract
OBJETIVOS: Identificar precocemente a prevalência de aterosclerose, por causa do espessamento do complexo médio-intimal das carótidas comuns e do índice tornozelo-braço. Essas medidas foram relacionadas com os fatores de risco clássicos de aterosclerose e os específicos dos infectados pelo HIV (tempo de doença, tempo de tratamento, tipo de tratamento, tipo de terapia antirretroviral utilizada, CD4 e carga viral). MÉTODOS: Setenta casos infectados com o HIV foram avaliados pela medida automática do complexo médio-intimal nas carótidas e do índice tornozelo-braço. Consideraram-se os fatores de risco clássicos de aterosclerose (idade, sexo, hipertensão arterial sistêmica, tabagismo, hipercolesterolemia, hipertrigliceridemia, obesidade e história familiar de evento cardiovascular), as medidas antropométricas e as variáveis relacionadas ao HIV. O nível de significância assumido foi de 5%. RESULTADOS: O tempo médio de diagnóstico do HIV foi de 104,9 meses e de tratamento foi de 97,9 meses. Quanto ao tipo de tratamento, 47 (67,1%) fizeram uso de inibidor de protease por mais de seis meses e 36 (51,4%) estão em uso atualmente. O índice tornozelo-braço estava aumentado em um único paciente (0,7%) e não se evidenciou espessamento do complexo médio-intimal em nenhum indivíduo. Não existiu associação significante da medida do complexo médio-intimal da carótida comum direita com nenhuma das variáveis analisadas. CONCLUSÕES: Indivíduos jovens, sob o uso de terapia antirretroviral por cinco anos ou mais, não apresentaram espessamento do complexo médio-intimal ou aumento do índice tornozelo-braço. Não houve diferença do espessamento do complexo médio-intimal associada ao tipo de esquema antirretroviral utilizado ou nível de carga viral.

Abstract
The introduction of combination antiretroviral therapy (cART) has substantially decreased mortality among the HIV-infected population. In this setting, cardiovascular disease (CVD) has become a leading cause of morbidity and mortality. Compared with the general population, higher rates of myocardial infarction as well as a high prevalence of subclinical coronary atherosclerosis have been found in the HIV-infected population. It has been suggested that in HIV-infected patients, the atherosclerotic burden is not based solely on traditional cardiovascular risk factors. The interplay of other mechanisms such as chronic inflammation, effects of cART or immune activation after initiation of cART may predispose to accelerated and increased risk of CVD. Effective treatment are available today to reduce CVD in at-risk patients, and therefore early detection of subclinical coronary atherosclerosis is important. However, the mechanisms behind the development of CVD in HIV-infected patients may limit the usefulness of the traditional noninvasive screening tools for CVD used in the general population. This review will focus on the different plausible mechanisms behind the increased risk of CVD and the noninvasive methods by which atherosclerosis may be assessed in the HIV-infected population.

Abstract
Atherosclerotic cardiovascular disease (CVD) has become an important cause of morbidity and mortality among individuals with human immunodeficiency virus (HIV) infection with access to antiretroviral medications, as the risk for AIDS has fallen and life expectancy improved. Traditional CVD risk factors are often more common among individuals with HIV infection, and traditional prevention strategies remain important. Recent data have revealed that untreated HIV infection itself amplifies additional pro-atherogenic mechanisms related to immune activation, inflammation, coagulation, and lipoprotein particle changes (e.g. high-density lipoprotein particles). Some of these mechanisms are attenuated, though incompletely, with antiretroviral therapy (ART)-related suppression of HIV replication. Exposure to ART is also associated with variable toxicity that may simultaneously decrease (via viral suppression) and increase CVD risk. Ultimately, additional adjunctive treatment will be needed to mitigate premature CVD risk among contemporary HIV-infected patients with access to ART.

Abstract
Life expectancy in HIV-infected individuals has been greatly enhanced through immunologic restoration and virologic suppression resulting from antiretroviral therapy. Current clinical HIV care in Western countries focuses on treatment of drug toxicities and prevention of comorbidities. These non-AIDS HIV-related comorbidities, such as cardiovascular disease, occur even in individuals with virologic suppression and manifest at an earlier age than when normally presenting in the general population. While traditional risk factors are present in many HIV-infected individuals who develop cardiovascular disease, the additional roles of HIV-related chronic inflammation and immune activation as well as chronic HIV viremia may be significant. This review provides current evidence for the contributions of the virus, in terms of both chronic viremia and its contribution via chronic low-level inflammation, immune activation, premature immune senescence and dyslipidemia, to the pathogenesis of HIV-related cardiovascular disease, and balances this against the propensity of specific antiretroviral therapies to cause cardiovascular disease, in particular through altered cholesterol metabolism.

Abstract
The pathogenesis of arteriosclerosis in HIV-infected patients is complex. Both patient-related cardiovascular risk factors (CVRF) established for the general population and those related to highly-active antiretroviral therapy (HAART) and HIV infection per se are involved. Some traditional CVRF are more frequent in HIV infected patients than in the general population. In developed countries, HIV infection is more frequent among men and, due to HAART, their life expectancy has significantly increased. The prevalence of smoking (37-72%) is higher than in the general population, as is that of diabetes mellitus (17%), insulin resistance (17-51%), dyslipidemia (22-49%) and hypertriglyceridemia (34%). The higher prevalence in these patients is probably due to lifestyle and length of exposure to HAART, especially to certain antiretroviral drugs. Although overall cardiovascular risk in patients with HIV remains low, CVRF established for the general population become more important with increasing age. Longitudinal cohort studies indicate the magnitude of the association of these risk factors with cardiovascular disease in patients with HIV infection. In view of all the factors that intervene in HIV infection, specific mathematical models should be designed for this population that would allow individual cardiovascular risk to be calculated in each patient and measures for cardiovascular prevention to be established.
