Abstract
PURPOSE OF REVIEW HIV-associated cardiac disease was well recognized in the preantiretroviral (ART) era among children with perinatally-acquired HIV infection (PHIV). While ART has dramatically improved survival, it has become increasingly apparent that individuals with PHIV continue to experience multisystem co-morbidities. We review the cardiac and vascular manifestations in people growing up with PHIV in the ART era. RECENT FINDINGS ART has resulted in a drop in incidence of serious cardiac morbidity. However, there is a substantial body of evidence that demonstrates that cardiac and vascular structural and functional abnormalities, mostly subclinical, are common in people with PHIV taking ART. Studies have considerable heterogeneity with respect to types of cardiovascular assessments used. HIV-mediated chronic inflammation and potentially effects of ART contribute to these abnormalities. The long-term clinical significance of these abnormalities remains unknown as studies have mainly been cross-sectional, but it is likely that the burden of cardiovascular disease will grow as individuals with PHIV age and the prevalence of traditional risk factors increases. SUMMARY Understanding the pathogenesis of cardiovascular disease in PHIV, is critical to inform screening and interventional strategies. Longitudinal studies are also needed to understand the natural history of cardiovascular abnormalities and incidence of clinical outcomes.

Endothelial dysfunction, a predictor of cardiovascular disease in HIV patients on antiretroviral therapy: A systematic review and meta-analysis. Thromb Res 2024; 234:101-112. [PMID: 38211378 DOI: 10.1016/j.thromres.2023.12.011] [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: 09/27/2023] [Revised: 12/02/2023] [Accepted: 12/18/2023] [Indexed: 01/13/2024]
Abstract
Aim Although antiretroviral therapy (ART) is available, the rate of new HIV infections is alarming. With this trend, it is anticipated that the use of ART will continue to rise, potentially resulting in associated vascular disorders. Therefore, we aimed to examine the impact of ART on endothelial function in people living with HIV (PLHIV), a predictor of cardiovascular diseases. METHOD A comprehensive search for evidence was made on PubMed and Scopus on May 06, 2023, following the Preferred Reporting Items for Systematic Review and Meta-analysis. Cochrane and Newcastle-Ottawa quality assessment scales were used to evaluate quality, while the metaHun web tool and Review Manager version 5.4.1 were used for analysis. Subgroup, sensitivity, and publication bias were conducted for each outcome measure. RESULTS We identified 37 studies, including a sample size of 3700 with 2265 individuals on ART. The analyzed evidence showed a large significant effect of ART on vascular cell adhesion molecule-1, with a standardized mean difference (SMD) of -1.23 (95 % CI: -1.72, -0.74; p = 0.0013). Similarly, a significant medium effect of ART was observed on intercellular cell adhesion molecule-1 in PLHIV, with an SMD of -1.28 (95 % CI: -2.00, -0.56; p = 0.0231) compared to the control group. Furthermore, ART exhibited a significant but small effect on flow-mediated dilation (FMD) with an SMD of -0.40 (95 % CI: -0.62, -0.19, p = 0.0159). CONCLUSION Our findings show an improved endothelial function in PLHIV on ART, as demonstrated by reduced adhesion molecules; however, ART exhibited a small effect on FMD, thus suggesting PLHIV on ART may still be at risk of endothelial dysfunction and further cardiovascular diseases.

Abstract
BACKGROUND Peripheral arterial disease (PAD) is common in HIV patients and can be diagnosed noninvasively using the ankle-brachial index (ABI). The burden of PAD has not been investigated in Ghanaian HIV patients. We investigated the prevalence and risk factors associated with PAD in HIV patients at a periurban hospital in Ghana. METHODS In a case-control design, ABI was measured in 158 cART-treated HIV patients, 150 cART-naïve HIV patients and 156 non-HIV controls with no clinical symptoms of CVDs. PAD was defined as ABI ≤ 0.9. A structured questionnaire was used to collect socio-demographic and clinical data. Fasting venous blood samples were collected to measure plasma levels of glucose, lipid profile, and CD4+ lymphocytes. RESULTS The prevalence of PAD was 13.9% among cART-treated HIV patients, 21.3% among cART-naïve HIV patients, and 15.4% among non-HIV controls. Patients with PAD had increased odds of having low CD4+ cell counts [OR (95% CI) = 3.68 (1.41-12.85)]. In cART-treated HIV patients, those on TDF-based [5.76 (1.1-30.01), p = 0.038] and EFV-based [9.28 (1.51-57.12), p = 0.016] regimens had increased odds of having PAD. CONCLUSION In our study population, there was no difference in the prevalence of PAD between cART-treated HIV patients compared to cART-naïve HIV patients or non-HIV controls. Having a low CD4 cell count and being on TDF- or EFV-based regimens were associated with an increased likelihood of having PAD.

Abstract
BACKGROUND Several studies suggest that patients infected with the human immunodeficiency virus (HIV) under highly active antiretroviral therapy (HAART) have a higher cardiovascular risk than the general population. Arterial stiffness is an independent predictor of cardiovascular events and can be measured through carotid-femoral pulse wave velocity (PWV). The objectives of this study were to characterize a sample of HIV-infected patients under HAART regarding cardiovascular risk, compare PWV values of this group with those of uninfected controls, and investigate predictors of PWV in the HIV-infected group. METHODS PWV was measured, and data was collected from a sample of 125 HIV-infected patients under HAART. PWV measurements in the study group were compared with those in a control group of 250 subjects similar in sex, age, prevalence of hypertension, and type 2 diabetes mellitus (DM). A linear regression model was constructed to identify predictors of PWV in the HIV-infected group. RESULTS In the HIV-infected group, composed mostly of men, the mean age and respective standard deviation were 48.6 ± 11.6 years. In this group, 112 individuals (89.6%) presented moderate to very high cardiovascular risk. Significant differences were found in median PWV between HIV-infected and control groups (8.56 vs. 8.00 m/s, p = .002). Age, peripheral systolic blood pressure, presence of DM, amount of alcohol consumed, and current CD4+ T cell count were independent predictors of PWV in the HIV-infected group. Conclusions: The HIV-infected group showed higher cardiovascular risk and arterial stiffness measurements than the general population. PWV may be an important predictor of subclinical cardiovascular disease in HIV-infected patients.

Abstract
BACKGROUND Prospective investigations on the risk of cardiovascular disease among youth with perinatally acquired human immunodeficiency virus (PHIV) in sub-Saharan Africa are lacking. METHODS A prospective observational cohort study was performed in 101 youth (aged 10-18 years) with PHIV and 97 who were human immunodeficiency virus (HIV) uninfected (HIV-), from 2017 to 2021 at the Joint Clinical Research Center in Uganda. Participants with PHIV were receiving antiretroviral therapy (ART) and had HIV-1 RNA levels ≤400 copies/mL. The common carotid artery intima-media thickness (IMT) and pulse wave velocity (PWV) were evaluated at baseline and at 96 weeks. Groups were compared using unpaired t-test, and potential predictors of IMT and PWV were assessed using quantile regression. RESULTS Of the 198 participants recruited at baseline, 168 (89 with PHIV, 79 HIV-) had measurements at 96 weeks. The median age (interquartile range) age was 13 (11-15) years; 52% were female, and 85% had viral loads <50 copies/mL that remained undetectable at week 96. The baseline mean common carotid artery IMT was slightly higher in participants with PHIV compared with controls (P < .01), and PWV did not differ between groups (P = .08). At week 96, IMT decreased and PWV increased in the PHIV group (P ≤ .03); IMT increased in the HIV- group (P = .03), with no change in PWV (P = .92). In longitudinal analyses in those with PHIV, longer ART duration was associated with lower PWV (β = .008 [95% confidence interval, -.008 to .003]), and abacavir use with greater IMT (β = .043 [.012-.074]). CONCLUSIONS In healthy Ugandan youth with PHIV, virally suppressed by ART, the common carotid artery IMT did not progress over 2 years. Prolonged and early ART may prevent progression of subclinical vascular disease, while prolonged use of abacavir may increase it.

Abstract
INTRODUCTION Metabolic alterations and body fat redistribution are common in people living with HIV using antiretroviral therapy and increase the risk of premature cardiovascular diseases. AIM To verify the presence of difference in the lipid and glycemic profile in relation to different total body and trunk fat phenotypes in children and adolescents diagnosed with HIV+. METHOD This is a cross-sectional study carried out with 62 children and adolescents diagnosed with HIV+. Lipid and glycemic profiles were obtained from blood samples. Total and trunk fat mass (FM) was obtained by DXA. Analysis of covariance was used to verify if there is difference in the lipid and glycemic profile between total body and trunk fat phenotypes. RESULTS In males, in the covariate-adjusted model, it was observed that boys with high total FM had higher triglyceride values (mean: 164.9 mg/dl-1 ±31.2) compared to those with low and adequate total FM. In females, in adjusted models, it was observed that girls with high total FM had higher total cholesterol (mean: 181.6 mg/dl-1 ±13.8) and LDL-C values (mean: 111.8 mg/dl-1 ±12.0), compared to those with low and adequate total FM. Girls with trunk FM had higher total cholesterol (mean: 181.6 mg/dl-1 ± 13.8), LDL-C (mean: 71.3 mg/dl-1 ± 9.6) and blood glucose values (91.6 mg/dl-1 ± 2.2). CONCLUSION Boys with high total FM had higher triglyceride levels, while in females, it was observed that girls with high total FM and high trunk FM had higher total cholesterol, LDL-C and blood glucose values. High body fat in children and adolescents living with HIV is related to metabolic changes in the lipid and glycemic profile, with specificities of sex and fat location.

Abstract
BACKGROUND AND AIMS Perinatal HIV infection (PHIV) and prolonged use of antiretroviral therapy (ART) may increase the likelihood of developing subclinical vascular dysfunction at an early age. We conducted a systematic review to assess the effect of PHIV and ART on intima-media thickness (IMT), arterial stiffness and endothelial function in individuals aged 6-25 years. METHODS Medline, Embase and Web of Science were searched, and studies screened by two independent reviewers. We performed a meta-analysis on selected studies reporting on IMT. RESULTS A total of 680 studies were retrieved from the databases, with 21 studies deemed eligible for qualitative analysis. There were few studies assessing IMT, arterial stiffness and endothelial function. More than half of the studies found either increased IMT, stiffer arteries or impaired endothelial function in PHIV compared to uninfected controls. A minority of the studies reported that the two groups had similar vascular parameters, a conflicting finding. There was a lack of standardisation for IMT assessment and reporting in numerous studies. In a meta-analysis of seven studies with matching methodologies, IMT was higher in PHIV compared to uninfected controls, (mean difference, 0.05 (0.01-0.09; p = 0.01) but heterogeneity between the studies was substantial (I2, 96.7%; p < 0.001). CONCLUSIONS PHIV may affect vascular structure and function. Existing studies are generally small, often contradictory, and predominantly cross-sectional in design. Further studies are required to understand vascular health in PHIV to identify cardiovascular disease risk and improve interventional strategies aimed at prevention and treatment of early vascular changes in this population.

Abstract
PURPOSE OF THE REVIEW To describe trends and clinical characteristics of HIV and cerebrovascular disease between 1990 and 2021 in LMICs and identify the gaps in our understanding. RECENT FINDINGS In the era of antiretroviral therapy (ART), people living with HIV (PLWH) live longer and risk excess cerebrovascular events due to ageing and HIV-driven factors. Despite the highest burden of HIV infection in low-to-middle income countries, there is underreporting in the literature of cerebrovascular events in this population. We systematically reviewed published literature for primary clinical studies in adult PLWH and cerebrovascular disease in LMICs. The clinical phenotype of cerebrovascular disease among PLWH over the last three decades in LMICs has evolved and transitioned to an older group with overlapping cerebrovascular risk factors. There is an important need to increase research in this population and standardise reporting to facilitate understanding, guide development of appropriate interventions, and evaluate their impact.

Abstract
BACKGROUND Young South African women are faced with a dual epidemic of HIV and obesity, placing them at a high risk of developing atherosclerotic cardiovascular disease (CVD). We sought to determine the prevalence of CVD risk factors in a cohort of reproductive-aged South African women living with HIV (WLHIV). METHODS While the main purpose of an ongoing intervention study is the reduction of cardiovascular disease through the integration of CVD screening and prevention in the HIV management plan for women of reproductive age (ISCHeMiA trial), we present the prevalence of risk factors for CVD in this cohort of young women at baseline. Sociodemographic, conventional CVD risk factors, HIV-related factors and self body image perception were assessed through study questionnaires and standardized clinical and laboratory procedures. RESULTS Of the 372 WLHIV enrolled from November 2018 to May 2019, 97% had received efavirenz-based antiretroviral treatment (ART) for at least 1 year and 67.5% (248/367) of women were overweight or obese at the time of enrolment. The prevalence of metabolic syndrome was 17.6% (95%CI 11.6-22.8) at a median age of 35 years (IQR 30.5-40.5). A significant proportion of women had abnormally low levels of high-density lipoprotein (43.2%, 80/185) and elevated levels of high sensitivity C-reactive protein (59.5%, 110/185). Seventy five percent of overweight women with an increased waist circumference reported to be satisfied with their body image. CONCLUSIONS The high prevalence of metabolic syndrome, obesity and elevated markers of inflammation in young South African WLHIV, underscores the need for a proactive integrated management approach to prevent atherosclerotic cardiovascular disease in low and middle income settings.

Abstract
PURPOSE OF REVIEW Antiretroviral therapy (ART) scale-up has dramatically reduced rates of pediatric HIV mortality and morbidity. Children living with perinatally acquired HIV (PHIV) are now expected to live through adolescence and well into adulthood, such that adolescents now represent the largest growing population living with HIV. This review aims to discuss the prevalence and mechanisms for cardiometabolic comorbidities in the setting of newer ART regimens and the research gaps that remain. RECENT FINDINGS Data highlight the continued risks of subclinical cardiometabolic complications in PHIV in the setting of newer ART. Novel techniques in imaging and omics may help identify early cardiometabolic abnormalities in this young population and potentially identify early changes in the mechanistic pathways related to these changes. Further studies to determine risk and management strategies of the cardiometabolic effects in PHIV adolescents, beyond ART, are warranted. Focus should be on prevention of these complications in youth to avoid new epidemic of diabetes and cardiovascular disease when these youths become aging adults.

Subclinical Vascular Disease in Children With Human Immunodeficiency Virus in Uganda Is Associated With Intestinal Barrier Dysfunction. Clin Infect Dis 2021; 71:3025-3032. [PMID: 31807748 DOI: 10.1093/cid/ciz1141] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2019] [Accepted: 12/04/2019] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND The risk of cardiovascular disease (CVD) and its mechanisms in children living with perinatally acquired HIV (PHIV) in sub-Saharan Africa has been understudied. METHODS Mean common carotid artery intima-media thickness (IMT) and pulse-wave velocity (PWV) were evaluated in 101 PHIV and 96 HIV-negative (HIV-) children. PHIV were on ART, with HIV-1 RNA levels ≤400 copies/mL. We measured plasma and cellular markers of monocyte activation, T-cell activation, oxidized lipids, and gut integrity. RESULTS Overall median (interquartile range, Q1-Q3) age was 13 (11-15) years and 52% were females. Groups were similar by age, sex, and BMI. Median ART duration was 10 (8-11) years. PHIV had higher waist-hip ratio, triglycerides, and insulin resistance (P ≤ .03). Median IMT was slightly thicker in PHIVs than HIV- children (1.05 vs 1.02 mm for mean IMT and 1.25 vs 1.21 mm for max IMT; P < .05), while PWV did not differ between groups (P = .06). In univariate analyses, lower BMI and oxidized LDL, and higher waist-hip ratio, hsCRP, and zonulin correlated with thicker IMT in PHIV (P ≤ .05). After adjustment for age, BMI, sex, CD4 cell count, triglycerides, and separately adding sCD163, sCD14, and hsCRP, higher levels of intestinal permeability as measured by zonulin remained associated with IMT (β = 0.03 and 0.02, respectively; P ≤ .03). CONCLUSIONS Our study shows that African PHIV have evidence of CVD risk and structural vascular changes despite viral suppression. Intestinal intestinal barrier dysfunction may be involved in the pathogenesis of subclinical vascular disease in this population.

The 2-hydroxy-nevirapine metabolite as a candidate for boosting apolipoprotein A1 and for modulating anti-HDL antibodies. Pharmacol Res 2021; 165:105446. [PMID: 33515705 DOI: 10.1016/j.phrs.2021.105446] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2020] [Revised: 01/09/2021] [Accepted: 01/12/2021] [Indexed: 11/24/2022]
Abstract
The antiretroviral nevirapine (NVP) is associated to a reduction of atherosclerotic lesions and increases in high-density lipoprotein (HDL)-cholesterol. Despite being a hepatotoxic drug, which forbids its re-purposing to other therapeutic areas, not all NVP metabolites have the same potential to induce toxicity. Our aim was to investigate the effects of NVP and its metabolites in an exploratory study, towards the identification of a candidate to boost HDL. A pilot prospective (n = 11) and a cross-sectional (n = 332) clinical study were performed with the following endpoints: HDL-cholesterol and apolipoprotein A1 (ApoA1) levels, anti-HDL and anti-ApoA1 antibodies titers, paraoxonase, arylesterase and lactonase activities of paraoxonase-1, and NVP's metabolite profile. NVP treatment increased HDL-cholesterol, ApoA1 and paraoxonase-1 activities, and lowered anti-HDL and anti-ApoA1 titers. In the prospective study, the temporal modulation induced by NVP was different for each HDL-related endpoint. The first observation was a decrease in the anti-HDL antibodies titers. In the cross-sectional study, the lower titers of anti-HDL antibodies were associated to the proportion of 2-hydroxy-NVP (p = 0.03). In vitro models of hepatocytes were employed to clarify the individual contribution of NVP's metabolites for ApoA1 modulation. Long-term incubations of NVP and 2-hydroxy-NVP in the metabolically competent 3D model caused an increase in ApoA1 reaching 43 % (p < 0.05) and 86 % (p < 0.001), respectively. These results support the contribution of drug biotransformation for NVP-induced HDL modulation, highlighting the role of 2-hydroxy-NVP as ApoA1 booster and its association to lower anti-HDL titers. This biotransformation-guided approach allowed us to identify a non-toxic NVP metabolite as a candidate for targeting HDL.

Abstract
The introduction of antiretroviral therapy (ART) has improved the life expectancy of patients infected with human immunodeficiency virus (HIV). However, this population is at an increased risk for noncommunicable diseases, including atherosclerotic cardiovascular disease (CVD). Both ART and viral infection may be potential contributors to the pathophysiology of HIV-related CVD. The mechanisms behind this remain unclear, but it is critical to delineate early biomarkers of cardiovascular risk in the HIV population. In this review, we postulate that potential biomarkers could include alterations to high-density lipoprotein (HDL). Indeed, recent data suggest that HIV and ART may induce structural changes of HDL, thus resulting in shifts in HDL subclass distribution and HDL functionality.

Cardiovascular disease risk in an urban African population: a cross-sectional analysis on the role of HIV and antiretroviral treatment. Retrovirology 2019; 16:37. [PMID: 31796103 PMCID: PMC6889610 DOI: 10.1186/s12977-019-0497-7] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2019] [Accepted: 11/22/2019] [Indexed: 01/19/2023] Open
Abstract
BACKGROUND Life expectancy is increasing in the HIV-positive population and age-related non-communicable diseases, such as cardiovascular disease, (CVD) are seen more frequently. This study investigated to what extent HIV and antiretroviral therapy (ART) is associated with CVD risk in an urban African population. METHODS A cross-sectional study was performed in Johannesburg, South Africa, between July 2016 and November 2017. Both HIV-positive adults (ART-naïve, or on first- or second-line ART), as well as age and sex matched HIV-negative controls who were family or friends of the HIV-positive participants were included. Data were collected on demographics, cardiovascular risk factors, HIV-related characteristics, carotid intima-media thickness (CIMT) and carotid distensibility. The association between HIV, ART and CIMT and distensibility was analysed with linear regression models, adjusting for age, gender and CVD risk factors. RESULTS The study included 548 participants, 337 (62%) females, age 38.3 ± 9.5 years of whom 104 (19.0%) were HIV-positive, ART-naïve; 94 (17.2%) were on first-line ART; 197 (35.9%) were on second-line ART; and 153 (27.9%) were HIV-negative. Participants on second-line ART had higher CIMT and lower distensibility compared to the other groups (p < 0.001). After adjustment for age, these outcomes were similar between groups. Further adjustment for CVD and HIV-related factors did not alter the findings. CONCLUSION Neither HIV nor ART was associated with CIMT or carotid distensibility in this urban African population. Longitudinal studies are needed to fully understand the relationship between HIV and CVD across different populations.

Abstract
BACKGROUND The contribution of immune activation to arterial stiffness and its reversibility in human immunodeficiency virus (HIV)-infected adults in sub-Saharan Africa is unknown. METHODS HIV-uninfected and HIV-infected Malawian adults initiating antiretroviral therapy (ART) with a CD4+ T-cell count of <100 cells/μL were enrolled and followed for 44 weeks; enrollment of infected adults occurred 2 weeks after ART initiation. We evaluated the relationship between carotid femoral pulse wave velocity (cfPWV) and T-cell activation (defined as HLA-DR+CD38+ T cells), exhaustion (define as PD-1+ T cells), and senescence (defined as CD57+ T cells) and monocyte subsets, using normal regression. RESULTS In 279 HIV-infected and 110 HIV-uninfected adults, 142 (37%) had hypertension. HIV was independently associated with a 12% higher cfPWV (P = .02) at baseline and a 14% higher cfPWV at week 10 (P = .02), but the increases resolved by week 22. CD4+ and CD8+ T-cell exhaustion were independently associated with a higher cfPWV at baseline (P = .02). At 44 weeks, arterial stiffness improved more in those with greater decreases in the percentage of CD8+ T cells and the percentage of PD-1+CD8+ T cells (P = .01 and P = .03, respectively). When considering HIV-infected participants alone, the adjusted arterial stiffness at week 44 tended to be lower in those with higher baseline percentage of PD-1+CD8+ T cells (P = .054). CONCLUSIONS PD-1+CD8+ T-cells are associated with HIV-related arterial stiffness, which remains elevated during the first 3 months of ART. Resources to prevent cardiovascular disease in sub-Saharan Africa should focus on blood pressure reduction and individuals with a low CD4+ T-cell count during early ART.

Abstract
OBJECTIVE The aim of this study was to estimate the long-term metabolic effects of initiating a lopinavir/ritonavir (LPV/r)-based regimen as a first-line therapy for HIV-infected children less than 3 years of age in resource-limited settings. DESIGN A prospective cohort study after conclusion of the P1060 randomized clinical trials (ClinicalTrials.gov Identifier: NCT00307151), with an overall follow-up of 7 years. METHODS Longitudinal total cholesterol and triglyceride measures were compared between 222 and 227 children randomized to initiate LPV/r and nevirapine (NVP)-based regimens, respectively. Adipokines (adiponectin and leptin) and biomarkers of inflammation [C-reactive protein and interleukin (IL)-6], microbial translocation (lipopolysaccharide) and immune activation (sCD14), measured in 117 participants at a median of 45 weeks of follow-up, were also compared by a randomized arm. RESULTS Mean total cholesterol and the percentage of participants with borderline or high total cholesterol was higher in the LPV/r arm from years 3 to 7 of follow-up than in the NVP arm (adjusted relative differences ranging from 10.9 to 23.4 mg/dl and adjusted relative risks ranging from a 60% increased risk to a more than four-fold increased risk for cholesterol ≥170 mg/dl at 7 years of follow-up). Initiation of a LPV/r-based regimen was not associated with high triglycerides over follow-up or large differences in markers of metabolic syndrome, inflammation, microbial translocation or immune activation. CONCLUSION Given the virologic superiority of LPV/r-based regimens in young children and open questions regarding the roll-out of dolutegravir in resource-limited settings, children are currently being maintained on LPV/r-based regimens. Our results suggest continual assessment of total cholesterol among young children initiating a LPV/r-based regimen to monitor cardiometabolic health.

Abstract
Highly active anti-retroviral therapy has proved successful in reducing morbidity and mortality associated with HIV infection though it has been linked to increased risk of cardiovascular disease. To date, the direct effects of the anti-retroviral drugs Efavirenz, Tenofovir and Emtricitabine on the vasculature relaxant response have not been elucidated, which impaired may predispose individuals to cardiovascular disease. Increased cellular oxidative stress and overactivation of the DNA repair enzyme poly (ADP-ribose) polymerase (PARP) have been identified as central mediators of vascular dysfunction. The aim of this study was to investigate whether exposure to Efavirenz, Tenofovir or Emtricitabine directly causes endothelial cell dysfunction via overactivation of PARP. Exposure of ex vivo male rat aortic rings or in vitro endothelial cells to Efavirenz but not Tenofovir or Emtricitabine impaired the acetylcholine-mediated relaxant response, increased cellular oxidative stress and PARP activity, decreased cell viability and increased apoptosis and necrosis. Pharmacological inhibition of PARP protected against the Efavirenz-mediated impairment of vascular relaxation and endothelial cell dysfunction. Oestrogen exposure also protected against the Efavirenz-mediated inhibition of the vascular relaxant response, cell dysfunction and increased PARP activation. In conclusion, Efavirenz directly impairs endothelial cell function, which may account for the increased risk of developing cardiovascular complications with anti-retroviral therapy.

Abstract
PURPOSE OF REVIEW Perinatally HIV-infected adolescents may be at increased risk of noninfectious comorbidities later in life. This review summarizes recent advances in the understanding of noncommunicable diseases (NCD) among HIV-infected adolescents in high-income and lower middle-income countries, and identifies key questions that remain unanswered. We review atherosclerotic vascular disease (AVD), chronic bone disease (CBD), chronic kidney disease (CKD), and chronic lung disease (CLD). RECENT FINDINGS Persistent immune activation and inflammation underlie the pathogenesis of AVD, highlighting the importance of treatment adherence and maintenance of viral suppression, and the need to evaluate interventions to decrease risk. Tenofovir disoproxil fumarate (TDF) and trials of vitamin D supplementation have been the focus of recent studies of CBD with limited studies to date evaluating tenofovir alafenamide as an alternative to TDF for decreasing risk for bone and renal adverse effects among HIV-infected adolescents. Recent studies of CKD have focused primarily on estimating prevalence in different settings whereas studies of CLD are limited. SUMMARY As perinatally HIV-infected children age into adolescence and adulthood with effective long-term ART, it is necessary to continue to evaluate their risks for noninfectious comorbidities and complications, understand mechanisms underlying their risks, and identify and evaluate interventions specifically in this population.
