Abstract
Whether, and how, co-occurring HIV-1 infection (HIV) and tuberculosis (TB) impact cardiovascular status, especially in adolescents with perinatally acquired HIV (APHIV), have not been examined. We hypothesized that APHIV with previous active TB have worse cardiac efficiency than APHIV without TB, which is mediated by increased inflammation. Arterial elastance (Ea) and ventricular end-systolic elastance (Ees) were assessed by cardiovascular magnetic resonance, and ventriculoarterial coupling (VAC) estimated as Ea/Ees ratio. Inflammation was measured by high sensitivity C-reactive protein (hsCRP). Previous TB in APHIV was associated with reduced cardiac efficiency, related to an altered ventriculoarterial coupling. However, we did not find evidence of hsCRP mediated effects in the association between prior TB and cardiac efficiency. The clinical significance of these findings requires further study, including a wider range of biomarkers of specific immune pathways.

Abstract
BACKGROUND Youth living with perinatally acquired HIV infection (YLPHIV) are at risk of developing atherosclerotic cardiovascular disease. METHODS We determined the Pathobiological Determinants of Atherosclerosis in Youth (PDAY) coronary arteries (CA) and abdominal aorta (AA) risk scores among YLPHIV who are ≥15 years old in Cape Town Adolescent and Antiretroviral Cohort. PDAY score was calculated using non-high-density lipoprotein, high-density lipoprotein cholesterol, hyperglycemia, hypertension, obesity, and smoking; a score ≥1 was considered elevated. HIV viremia was categorized as sustained (SV) = viral load (VL) >50 copies/mL, transient (TV) = mix of VL >50 and ≤50 copies/mL, or sustained-virologic suppression = VL <50 copies/mL throughout the study. Among YLPHIV, logistic models were fit to assess factors associated with elevated PDAY. RESULTS Overall, 218 YLPHIV [median age 16.8 (interquartile range: 15.9-17.8) years, male 47%] were included. Among YLPHIV, 8% (n = 17) had SV, and 54% (n = 118) had TV. Median antiretroviral therapy (ART) duration was 12 (interquartile range: 8-14) years. Among YLPHIV, 30.3% and 18.4% had elevated PDAY for CA and AA, respectively.Among YLPHIV, SV [adjusted odds ratio (aOR) = 18.4, P < 0.01] and TV (aOR = 2.10, P = 0.04) compared with virologic suppression and ART duration in years (aOR = 1.12, P = 0.03) were associated with elevated CA. Male sex was associated with both elevated CA and AA (aOR = 2.14, P = 0.02, and aOR = 3.43, P = 0.01, respectively) and association of SV with elevated AA (aOR = 3.24, P = 0.09). CONCLUSIONS A substantial proportion of YLPHIV have PDAY scores reflecting increased aggregate atherosclerotic risk. Among YLPHIV, viremia, lifetime ART duration, and male sex contribute to this risk, highlighting the importance of HIV control and the need to monitor cardiometabolic health.

Abstract
Diastolic dysfunction (DD) refers to abnormalities in the mechanical function of the left ventricle (LV) during diastole. Severe LVDD can cause symptoms and the signs of heart failure (HF) in the setting of normal or near normal LV systolic function and is referred to as diastolic HF or HF with preserved ejection fraction (HFpEF). Pediatric cardiologists have long speculated HFpEF in children with congenital heart disease and cardiomyopathy. However, understanding the risk factors, clinical course, and validated biomarkers predictive of the outcome of HFpEF in children is challenging due to heterogeneous etiologies and overlapping pathophysiological mechanisms. The natural history of HFpEF varies depending upon the patient's age, sex, race, geographic location, nutritional status, biochemical risk factors, underlying heart disease, and genetic-environmental interaction, among other factors. Pediatric onset HFpEF is often not the same disease as in adults. Advances in the noninvasive evaluation of the LV diastolic function by strain, and strain rate analysis with speckle-tracking echocardiography, tissue Doppler imaging, and cardiac magnetic resonance imaging have increased our understanding of the HFpEF in children. This review addresses HFpEF in children and identifies knowledge gaps in the underlying etiologies, pathogenesis, diagnosis, and management, especially compared to adults with HFpEF.

Abstract
Background Human immunodeficiency virus (HIV) affects many organ systems in the body including the cardiovascular system, often manifesting as a subclinical left ventricular (LV) systolic dysfunction that may progress to heart failure. Aim This study assessed the prevalence of LV systolic dysfunction in children on highly active antiretroviral therapy (HAART) with established clinical stage 1 HIV-disease. Materials and Methods The study was a cross-sectional comparative study conducted in Aminu Kano Teaching Hospital from April to August 2019 on 200. It involved study participants comprising 100 WHO clinical stage 1 HIV-infected children and 100 control subjects, aged between 1 and 18 years selected using systematic sampling method. Echocardiography was carried out on the study participants who had already completed a pretested questionnaire. Results Out of 100 HIV-infected children studied, 49 were males and 51 females (Male: Female ratio; 0.96:1.0). The mean age at diagnosis of HIV infection was 2.6 (±2.6 years) and the median viral load was 35 copies/ml. The mean ejection and shortening fractions in HIV-infected children were 59.0% and 31.0%, respectively, compared to 64.4% and 34.0% in control subjects, respectively, and were statistically significant (P = 0.000). The prevalence of LV systolic dysfunction was 8.0% (8 out of 100) in HIV-infected children while the control groups had zero prevalence (P = 0.002). The age at diagnosis correlated negatively with LV systolic dysfunction (r = 0.23, P = 0.02). Conclusion This study found a subclinical LV systolic dysfunction in an HAART-established clinical stage 1 HIV-infected children. The age at diagnosis was negatively correlated with the LV systolic function. This study, therefore, support the inclusion of routine echocardiography into the evaluation of HIV-infected children.

Abstract
OBJECTIVE To evaluate if in-utero HIV exposure is associated with adverse cardiometabolic health outcomes at 5-8 years of age. DESIGN Prospective cohort study. METHODS We enrolled a random sample of HIV-exposed but uninfected (HEU) and HIV-unexposed children from the Drakenstein Child Health study, a longitudinal birth cohort study in Cape Town, South Africa, in a cardiometabolic health pilot study. Outcomes were assessed by trained study staff and included: anthropometry, body composition and size, blood pressure, fasting plasma glucose, HbA1c, lipids, and insulin resistance using HOMA-IR. We used multivariable linear and log-binomial regression to estimate associations between HIV-exposure and cardiometabolic outcomes, adjusted for child age, sex, height, body size, and maternal factors as appropriate. RESULTS We included 260 children (HEU n = 100, HIV-unexposed n = 160). HEU children had older mothers (median age 30 vs. 26 years), with minimal differences in gestational age and size at birth by HIV-exposure status. In multivariable analyses, HEU children had lower weight-for-age (mean difference -0.35, 95% confidence interval -0.66, -0.05), and height-for-age (mean difference -0.29, 95% confidence interval -0.56, -0.03; z-scores). There were no differences in adiposity, impaired glucose metabolism, or lipid levels by HIV-exposure status. Overall, 12% of children had blood pressure more than 90th percentile, with no differences by HIV-exposure status. CONCLUSION Overall, there were few differences in cardiometabolic outcomes between HEU and HIV-unexposed children in this South African cohort. Although these findings are reassuring, monitoring of cardiometabolic health is important as HEU and HIV-unexposed children enter adolescence and cardiometabolic risk trajectories become established.

Abstract
OBJECTIVE To assess cardiovascular effects of in-utero HIV and antiretroviral treatment (ART) exposure on offspring of HIV-positive mothers in Ethiopia. DESIGN HIV-positive and HIV-negative pregnancies were identified from a prospective cohort of women recruited at their first antenatal care visit in Ethiopia, using a nested case-control design. METHODS Fetal standard ultrasound and echocardiography were performed at 2237 weeks of pregnancy to assess fetal biometry and cardiac structure. Postnatal cardiovascular evaluation, including echocardiography and vascular assessment, was performed at 6 months of age. Cardiovascular data were correlated to HIV serostatus, antiretroviral drug exposure and HIV-unrelated maternal characteristics. RESULTS Fetuses from 29 HIV-positive and 67 HIV-negative women paired by gestational age at scan were included. Among HIV-positive women, 25 were on ART before conception, and 4 initiated ART during pregnancy. Estimated fetal weight was similar in both groups [mean 1873 g (standard deviation; SD 569) vs. 1839 g (SD 579) P = 0.79, respectively]. Fetal cardiac morphometry was similar with regard to maternal HIV serostatus: cardiothoracic ratio mean 0.26 (SD 0.05) vs. 0.25 (SD 0.06), P = 0.48; and septal wall thickness mean 4.03 mm (SD 0.58) vs. 3.98 mm (SD 0.70), P = 0.94. No significant cardiovascular differences were detected postnatally according to maternal HIV serostatus: septal wall thickness mean 5.46 mm (SD 0.65) vs. 5.49 (SD 0.89); P = 0.896; isovolumic relaxation time 55.08 ms (SD 6.57) vs. 56.56 (SD 6.74); P = 0.359. CONCLUSION In offspring of Ethiopian women, intrauterine exposure to HIV and ART were not associated with cardiovascular changes from fetal life up to infanthood.

Abstract
For a long time, pediatric heart failure (HF) with preserved systolic function (HFpEF) has been noted in patients with cardiomyopathies and congenital heart disease. HFpEF is infrequently reported in children and instead of using the HFpEF terminology the HF symptoms are attributed to diastolic dysfunction. Identifying HFpEF in children is challenging because of heterogeneous etiologies and unknown pathophysiological mechanisms. Advances in echocardiography and cardiac magnetic resonance imaging techniques have further increased our understanding of HFpEF in children. However, the literature does not describe the incidence, etiology, clinical features, and treatment of HFpEF in children. At present, treatment of HFpEF in children is extrapolated from clinical trials in adults. There are significant differences between pediatric and adult HF with reduced ejection fraction, supported by a lack of adequate response to adult HF therapies. Evidence-based clinical trials in children are still not available because of the difficulty of conducting trials with a limited number of pediatric patients with HF. The treatment of HFpEF in children is based upon the clinician's experience, and the majority of children receive off-level medications. There are significant differences between pediatric and adult HFpEF pharmacotherapies in many areas, including side-effect profiles, underlying pathophysiologies, the β-receptor physiology, and pharmacokinetics and pharmacodynamics. This review describes the present and future treatments for children with HFpEF compared with adults. This review also highlights the need to urgently test new therapies in children with HFpEF to demonstrate the safety and efficacy of drugs and devices with proven benefits in adults.

Abstract
Background There is growing concern about the long-term sequelae [a condition which is the consequence of a previous disease or injury] of perinatally acquired human immunodeficiency virus (HIV). Children living with HIV (CLHIV) present with cardiopulmonary impairments and decreased physical activity which may be due to poor endurance. Objectives Our study aimed to investigate the sub-maximal endurance of CLHIV compared to a non-infected comparison group. Methods In this cross-sectional descriptive study 346 CLHIV, between ages five and eleven years, were assessed using the Six Minute Walk Test (6MWT). Blood pressure, heart rate and oxygen saturation were measured pre-test, immediately post-test and five minutes post-test. Clinical and anthropometric data were recorded. Height and weight were assessed using a stadiometer and a digital scale, respectively. Results 175 CLHIV (52% female) and 171 children without HIV (46% female) participated. All children were Black African. The CLHIV all initiated antiretroviral therapy (ART) at a young age (mean 8.7 months, standard deviation 6.7) and their disease was well controlled (viral load < 1000copies/ml). There were no statistically significant differences in submaximal endurance between the two groups (p = 0.831). Age of starting ART and stunted growth were negatively associated (r = -2.8 (p = 0.019) and r = -46.1 (p = 0.027), respectively) with distance walked in the 6MWT by girls living with HIV. Conclusion CLHIV who initiate ART early with well-controlled disease are able to attain submaximal endurance levels similar to their uninfected peers. Clinical implications Endurance and physical activity should be monitored in CLHIV. Submaximal endurance levels may improve with age and biological maturation.

Abstract
A late preterm infant had pulmonary hypertension caused by a variety of mechanisms leading to complex management. This child had complete atrioventricular septal defect associated with mild left ventricular hypoplasia and Down syndrome diagnosed prenatally. The mother had been treated by antiretroviral HIV treatment during pregnancy. Aortic coarctation was diagnosed and rapidly repaired. After surgery, he required noninvasive ventilation for persisting elevated PCO2. Pulmonary CT scan showed normal bronchial tree, lung parenchymal abnormalities with mosaic aspect and hyperlucent zones, and indirect signs of lung hypoplasia with peripheral microbubbles. During follow-up, severe pulmonary hypertension was diagnosed on echocardiography without recoarctation, significant intracardiac shunting or diastolic dysfunction. The patient died after four months unable to be weaned from noninvasive ventilation. Post mortem lung biopsy showed abnormally muscularized arterioles with intimal fibrosis and pulmonary immaturity. Gentetic screening identified a BMPR-2 mutation. This patient illustrates the multifactorial origin of pulmonary hypertension in the neonatal period. The respective contribution of left-to-right shunt, post-capillary obstruction, and abnormally elevated pulmonary vascular resistances led to perform right heart catheterization to exclude excessive shunting and restrictive physiology of the left heart. Subjects with Down syndrome are also highly susceptible to decreased lung vascular and alveolar growth, which may increase the risk for pulmonary hypertension and lung hypoplasia. This case highlights two issues. The first one is that right heart catheterization should be discussed in neonates with unexplained pulmonary hypertension and the second is to extend indications of genetic testing for pulmonary hypertension genes in neonates who have unusual course of neonatal pulmonary hypertension, particularly in the setting of associated congenital heart disease (CHD).

Abstract
Background: The adverse effects of antiretroviral therapy associated with complications generated by human immunodeficiency virus (HIV) promote impairments in physical fitness in adolescents. Objective: To analyze the aerobic capacity, muscle strength, and body composition of adolescents living with HIV compared with a healthy population of the same age. Methods: Searches were performed in the MEDLINE, Embase, Web of Science, Scopus and SportDiscus databases until September 2019 and updated in April 2020. Eligibility Criteria: adolescents of both sexes in the age group from 10 to 19 years; living with HIV; cross-sectional, case–control, cohort studies; comparing with a healthy population. Mean differences and 95% Confidence intervals (CIs) were calculated using RevMan (software for systematic reviews). Results: Five articles were included, involving 197 adolescents living with HIV (16 to 18 years) and 185 without infection (13 to 18 years), with the sample in each study ranging from 15 to 65 adolescents. Aerobic capacity and muscle strength were reduced in adolescents with HIV, and body mass index was also significantly lower in this group. Conclusion: Adolescents living with HIV have impaired cardiorespiratory fitness, muscle strength, and body composition when compared to their uninfected peers. However, this systematic review provides limited evidence on the differences between the physical fitness outcomes of adolescents living with HIV compared to healthy adolescents.

Abstract
BACKGROUND Human immunodeficiency virus (HIV) and antiretroviral therapy (ART) confer cardiovascular disease (CVD) risk in adults with HIV. Few studies have assessed endothelial dysfunction (ED), an early marker of subclinical CVD risk, in youth living with perinatally acquired HIV (YLPHIV). METHODS Using peripheral arterial tonometry, we compared ED in YLPHIV and age-matched youth without HIV. A reactive hyperemic index ≤1.35 was defined as ED. Eligible participants included those aged 9-14 years and on ART ≥6 months at enrollment. RESULTS Overall, 431 YLPHIV and 93 youth without HIV with a median age of 14.1 versus 13.9 years, respectively, were included. YLPHIV had a lower BMI z score (BMIZ; -0.2 vs 0.4; P < .01) but higher rates of hypercholesterolemia (10% vs 1%; P = .01) than youth without HIV. Among YLPHIV, mean log viral load (VL) was 4.83 copies/mL with 21.7% having a CD4 count <500 cell/mm3; median duration on ART was 9.8 years with 38% initiating at <2 years of age. YLPHIV had higher rates of ED than youth without HIV (50% vs 34%; P = .01); this relationship persisted after adjusting for age, sex, BMIZ, elevated BP, and hypercholesterolemia (RR, 1.43; P = .02). Among YLPHIV, CD4 count >500 cell/mm3 (RR, 1.04; P = .76), VL (RR, 1.01; P = .78), and current ART class (protease inhibitor based vs nonnucleoside inhibitor based: relative risk, 0.90; P = .186) were not associated with ED after adjustment. CONCLUSIONS Even after adjusting for physiologic differences, YLPHIV appear to be at increased risk of ED compared with age-matched youth without HIV. These findings have important implications for the life course of YLPHIV who may be at increased risk of premature CVD and complications.

Abstract
Background Cardiovascular abnormalities are not much reported among human immunodeficiency virus (HIV) infected children especially in Africa where there is high HIV disease. In addition, the use of highly active antiretroviral therapy (HAART) in such children may have a protective effect on the cardiovascular system. Methods Cross-sectional study of randomly selected eighty HIV infected and 80 aged matched non- HIV-infected children were used. HIV-infected children were on HAART for more than 5years and had steadily received the treatment for 6 months prior to the time of the tests. Heights and weights were measured and body mass index calculated. Cardiac indices evaluated were heart rate (HR), PR interval, QRS duration, QT/QTC Interval, P/QRS/T Axis, RV5/SV1 voltage and RV5+SV1 voltage. Results The average heart rate was significantly higher among HIV infected children on HAART than their non-infected counterparts (P= 0.019). At 0.05 significance level, their PR interval was significantly higher than those in the control group (P=0.050). The average QRS duration result also showed a significant difference between that of test and control subjects (P = 0.022) Conclusion The HAART usage possibly improved the cardiovascular functioning in the infected children but the protective effects diminish with increase age and longer exposure

Abstract
BACKGROUND The effects of HIV and antiretroviral therapy on cardiovascular system of perinatally infected children throughout their development are not fully understood. OBJECTIVES To determine the prevalence of cardiac abnormalities in a retrospective cohort of perinatally HIV-infected patients and to investigate associations between echocardiographic and clinical data during their follow-up. METHODS Review of medical records and echocardiogram reports of 148 perinatally HIV-infected patients between January 1991 and December 2015. RESULTS Four hundred and eighty echocardiograms were analyzed and 46 (31%) patients showed cardiac abnormalities, frequently subclinical and transient. Nadir CD4 count was higher in patients with consistently normal echocardiogram: 263 (4-1480) versus 202 (5-1746) cells/μL, P = 0.021. Right ventricular (RV) dilation was detected in 18.9%, left ventricular (LV) dilation in 21.6%, septal hypertrophy in 12.2%, LV posterior wall hypertrophy in 6%, LV systolic dysfunction in 8% and pulmonary hypertension in 8.7% of patients. Opportunistic infections were associated with RV dilation [odds ratio (OR = 4.34; 1.78-10.53; P < 0.01)], pulmonary hypertension (OR = 8.78; 2.80-27.51; P < 0.01) and LV systolic dysfunction (OR = 5.38; 1.55-18.71; P < 0.01). Longer duration of highly active antiretroviral therapy was associated with reduced risk of LV dilation (OR = 0.91; 0.85-0.97; P < 0.01) and systolic dysfunction (OR = 0.71; 0.59-0.85; P < 0.01). Protease inhibitors use was associated with reduced risk of RV dilation (OR = 0.54; 0.30-0.97; P < 0.05), LV dilation (OR = 0.35; 0.21-0.60; P < 0.01) and LV systolic dysfunction (OR = 0.07; 0.02-0.31; P < 0.01). Higher CD4 count was associated with lower risk of LV systolic dysfunction (OR = 0.82; 0.69-0.98; P < 0.05). CONCLUSIONS Echocardiograms identified cardiac abnormalities among children with perinatally acquired HIV infection, and data suggest that immunologic status and therapeutic strategies throughout development can influence cardiac disease burden in this population.

Abstract
OBJECTIVE To define the prevalence of early cardiac dysfunction in children and young adults with perinatally acquired HIV and predictors of cardiac function. DESIGN Cross-sectional design. METHODS Early cardiac dysfunction was defined as left ventricular (LV) global longitudinal strain z-score less than -2 or myocardial performance index at least 0.5 with normal LV ejection fraction. Regression models were fitted to assess the relationship between measures of cardiac function and HIV RNA levels, clinical variables, and markers of inflammation. RESULTS Six hundred and forty-three individuals (mean age 14.1 ± 5.2 years) were enrolled. The average time on combination antiretroviral treatment was 6.8 ± 3.6 years. Nearly 28% of individuals met criteria for early cardiac dysfunction. Individuals with early cardiac dysfunction were older (15.3 vs. 13.5 years, P < 0.001), had more frequently detectable HIV RNA (52.5 vs. 41.7%, P = 0.018), were more likely exposed to azidothymidine or zidovudine (ZDV) (55.6 vs. 41.2%, P = 0.002), and had higher median level of plasma IL-6 concentrations (1.00 vs. 0.88 pg/ml, P = 0.011). Multivariable models show LV ejection fraction negatively associated with HIV RNA levels [β -0.18; 95% confidence interval (CI) -0.33, -0.03] and ZDV exposure (β -1.75; 95% CI -2.62, -0.88) and positively associated with proportion of life on combination antiretroviral treatment (β 2.65; 95% CI 0.90, 4.41). Higher myocardial performance index was positively associated with serum inflammation marker (IL-6 β 0.01; 95% CI 0.0001, 0.001). Left ventricular global longitudinal strain was not significantly associated with clinical and laboratory variables of interest. CONCLUSION Over one-quarter of children and young adults living with HIV demonstrated evidence of cardiac dysfunction, which may be associated with increasing levels of systemic inflammation.

Abstract
BACKGROUND Little is known about the cardiac health of perinatally HIV-infected (PHIV+) adolescents on antiretroviral therapy (ART) in sub-Saharan Africa. The authors examined cardiac structure and function in PHIV+ adolescents on ART compared with HIV-uninfected (HIV-) adolescents. METHODS Echocardiography was performed on PHIV+ and age- and sex-frequency-matched HIV- adolescents enrolled in the Cape Town Adolescent Antiretroviral Cohort. Participants were eligible if they were 9 to 14 years of age and had been on ART for ≥6 months. RESULTS Overall, 474 PHIV+ adolescents (median age, 12 years; 51% boys; mean age at ART initiation, 5 years) and 109 HIV- adolescents (median age, 11.8 years; 45% boys) were included. The mean duration on ART was 7 years, with 37% starting treatment before 2 years of age. Compared with HIV- adolescents, PHIV+ adolescents had higher median Z scores for left ventricular (LV) internal end-diastolic dimension, LV end-systolic posterior wall thickness, and end-systolic interventricular septal thickness. PHIV+ adolescents had a lower median Z score for right ventricular internal end-diastolic dimension as compared with HIV- adolescents. There was no difference in ejection fraction or diastolic function between groups. Later initiation of ART (after 6 years) was associated with increased risk for LV hypertrophy (odds ratio, 2.9; 95% CI, 1.3-6.6; P = .01) compared with those who started ART earlier. PHIV+ adolescents with World Health Organization stage IV HIV infection were at increased risk (odds ratio, 2.2; 95% CI, 1.0-4.6; P = .05) of having LV diastolic dysfunction compared with those with less advanced clinical disease. CONCLUSIONS This study revealed subtle differences in echocardiographic parameters between PHIV+ and HIV- adolescents. Although these were not clinically significant, starting ART at an older age was a significant risk factor for LV hypertrophy, while more advanced clinical disease was associated with LV diastolic dysfunction.

Abstract
HIV-uninfected children exposed prenatally to the virus and to prophylactic antiretroviral therapy are at an uncertain risk of long-term myocardial dysfunction. This study aimed to analyse the structure and function of their ventricles and to identify potential screening tools for this at-risk population. One hundred and fifteen children (77 exposed vs 38 controls) aged between 2.7 and 16.2 years were included. An echocardiographic study was performed where both ventricles' dimensions and systolic functions were evaluated. In the left ventricle, parameters related to diastolic function were also analysed. Tissue Doppler values were determined in the basal state and after passive leg raising. Serologic analysis of amino-terminal pro-B-type natriuretic peptide (NT-proBNP) was carried out. The two groups had identical ventricular sizes and left ventricular diastolic functions. However, contractility assessed by myocardial peak systolic velocity was significantly inferior in the exposed group. These systolic echocardiographic differences were present despite similar values of NT-proBNP in both groups.Conclusion: HIV-exposed uninfected children may be vulnerable to ventricular systolic dysfunction at long term. Cardiovascular surveillance and periodic monitoring of biventricular function are therefore recommended. Myocardial peak systolic velocity may be a useful screening tool for this purpose.What is Known:• Previous studies on HIV-exposed uninfected children subjected prenatally to antiretroviral therapy have alerted to potential long-term cardiovascular toxicity effects on the left ventricle.What is New:• The study gives new insights on ventricular function and morphology in HIV-exposed uninfected children.• Myocardial peak systolic velocities are significantly inferior in this paediatric sub-group, therefore long-term cardiac surveillance is recommended.

Abstract
Supplemental Digital Content is Available in the Text. Background: Despite growing interest in undertaking research in adolescent HIV, the current pace of interventional research in particular remains very low compared with the needs of adolescents living with HIV (ALHIV). More robust evidence is needed to inform innovative and targeted interventions that bridge research gaps, inform policy, and improve outcomes for adolescents. A global research prioritization exercise was undertaken by WHO and CIPHER to focus efforts on priority research in the context of diminishing resources. Methods: The Child Health and Nutrition Research Initiative (CHNRI) methodology was adapted and used. Outcomes were reviewed by an expert group and 5 priority themes identified for testing, treatment, and service delivery, accounting for existing policies, published literature, and ongoing research. Results: A total of 986 research questions were submitted by 323 individuals from 67 countries. For HIV testing, priority themes included strategies and interventions to improve access, uptake, and linkage to care, and self-testing, particularly for key populations. For treatment, priorities included strategies to monitor and improve adherence, novel drug delivery systems, preventions and management of coinfections, optimal drug sequencing, and short- and long-term outcomes. For service delivery, priorities included service delivery models across the cascade, strategies to improve retention in care and sexual and reproductive health, support for pregnant ALHIV, and the provision of psychosocial support. Conclusions: This prioritized research agenda assists in focusing future research in ALHIV and will help to fill critical knowledge gaps. Key stakeholders, donors, program managers, and researchers should all support these priority questions and themes to collaboratively drive the adolescent HIV research agenda forward.

Abstract
BACKGROUND Mitochondrial toxicity related to maternal combined antiretroviral treatment (cART) may have an impact on the heart of HIV-exposed uninfected (HEU) fetuses. Our objective was to evaluate fetal cardiovascular and mitochondrial biomarkers in HIV pregnancies. METHODS Prospective cohort including 47 HIV-infected and 47 non HIV-infected pregnancies. Fetal echocardiography was performed at 26-32 weeks of pregnancy. Umbilical cord blood and placental tissue were collected to study mitochondrial DNA content (mtDNA) (ratio 12SrRNA/RNAseP) and mitochondrial function (cytochrome c oxidase, COX, enzymatic activity) normalized by mitochondrial content (citrate synthase, CS). RESULTS HEU fetuses showed hypertrophic hearts (left myocardial wall thickness: HIV mean 3.21 mm (SD 0.81) vs. non-HIV 2.72 (0.42), p = 0.012), with signs of systolic and diastolic dysfunction (isovolumic relaxation time: HIV 52.2 ms (8.85) vs. non-HIV 42.5 ms (7.30); p<0.001). Cord blood mitochondrial content was significantly increased in HIV-exposed fetuses (CS activity: HIV 82.9 nmol/min.mg of protein (SD 40.5) vs. non-HIV 56.7 nmol/min.mg of protein (28.4); p = 0.007), with no differences in mtDNA content and COX activity. Both myocardial and mitochondrial mass parameters were significantly associated with zidovudine exposure. CONCLUSIONS HEU fetuses showed signs of increased myocardial and mitochondrial mass associated with maternal zidovudine treatment, suggesting a fetal adaptive response to cART toxicity.

Abstract
Unacceptably high incidence of pediatric HIV despite worldwide increased access to antiretroviral therapy. The routine management of these children includes provision of antiretroviral therapy, and periodic assessment of its results and complications. However, no systematic assessment of the nutritional status, lipid profile or screening for cardiovascular disease is done. Our study aimed at describing the occurrence of cardiovascular abnormalities in HIV-infected children under antiretroviral therapy, and at determining the vital outcomes 5 years after. A prospective observational study was implemented at a dedicated HIV center in Maputo City, where we gathered detailed socio-demographic data and performed full cardiovascular evaluation, including transthoracic cardiac ultrasound. A total of 47 children were examined (24 male) of which 10 had abnormal cardiac ultrasound: impaired systolic function (5 children); three had congenital heart defects; one had severe rheumatic aortic regurgitation and one had tuberculous pericarditis. Heart failure was present in five children. The study also uncovered the presence of malnutrition (36 patients; 80% had BMI below 18.5 kg/m2) and anemia in a considerable proportion of children. On 5 year follow up there was one death due to malária; three new cases of left ventricular dysfunction occurred among children who had normal ultrasound on recruitment. Our results support systematic cardiovascular risk profiling and disease screening in HIV-infected children on antiretroviral therapy, using cardiac ultrasound wherever possible.

Abstract
OBJECTIVE To evaluate potential adverse associations of individual antiretroviral medications used in combination antiretroviral therapy regimens on cardiac structure and function in youth with perinatally-acquired HIV infection (PHIV). DESIGN PHIV youth (N = 325) enrolled in a prospective multisite cohort study had a single echocardiogram at age 7-16 years to evaluate cardiac function and structure. METHODS We applied several statistical approaches to evaluate associations between use of 18 individual antiretroviral medications with Z-scores for 11 measures of left ventricular function and structure. These included simultaneously evaluating all antiretroviral medications in adjusted linear regression models controlling for the false discovery rate (FDR), applying hierarchical models to estimate individual antiretroviral medication effects as deviations from drug class means, and evaluating latent measures of cardiac function and structure underlying multiple echocardiographic parameters. RESULTS Youth taking combination regimens with a protease inhibitor (69%) had significantly better cardiac function than those on other regimens. After FDR control and adjustment for other antiretroviral medications, no individual antiretroviral medication was significantly associated with any measure of left ventricular function, but zidovudine was associated with higher adjusted mean Z-scores for one measure of left ventricular structure (end-systolic wall stress). Factor analysis identified three latent factors: heart function, heart size, and heart wall stress. Lopinavir was associated with better heart function scores, whereas zidovudine was associated with higher wall stress scores. Zidovudine and nevirapine were associated with higher heart size factor scores. CONCLUSIONS Despite cardioprotective effects of combination regimens in PHIV youth, individual antiretroviral medications were associated with altered cardiac structure, which could progress to symptomatic cardiomyopathy in adulthood.

Abstract
PURPOSE OF REVIEW Introduction of combination antiretroviral therapy (ART) has increased the life expectancy of patients with HIV infection, allowing them to live longer with this chronic medical condition and consequently experiencing conditions such as cardiovascular diseases (CVDs). Several studies have investigated the increased risk of CVD in people living with HIV (PLWH). However, less is known about the exact mechanisms involved in this increased risk. Also, specific guidelines for management of CVD in PLWH have not been developed yet. In this article, we review the recent literature on the mechanisms involved in pathogenesis of CVD in PLWH, with an emphasis on coronary artery disease (CAD). RECENT FINDINGS Although initial studies suspected the increased prevalence of traditional CVD risk factors and side effects of ART to be involved in the increased CVD risk in PLWH, recent studies have uncovered the important role of chronic persistent inflammation in this increased risk. In addition, biomarkers of inflammation have been associated with both CVD events and subclinical CAD in this population. Lastly, recent studies and ongoing clinical trials have been investigating medical interventions that aim to reduce inflammation and cardiovascular events. Different mechanisms of inflammation have been examined in PLWH, including subclinical viremia, microbial translocation, and coinfection with other pathogens such as cytomegalovirus. Although inflammatory biomarkers have been consistently associated with CVD and subclinical CVD outcomes, their prognostic value is unknown. Recent and ongoing trials are exploring the benefits of anti-inflammatory drugs, statins, and antimicrobial translocation drugs on both inflammation and CVD risk among PLWH.

Abstract
AIM The aims of this study were to 1) determine if cardiac disease can be detected in HIV-infected children by strain imaging and 2) to evaluate differences in exercise performance between HIV-infected children on antiretroviral therapy (ART) and HIV-infected children not yet on ART and in HIV-uninfected children by 6-minute walk tests (6MWTs). METHODS This cross-sectional study evaluated cardiac function by echocardiogram and exercise performance by 6MWT in HIV-infected and HIV-uninfected children 4-18 years of age in Lilongwe, Malawi. Analyses compared HIV uninfected, HIV infected not yet on ART, and HIV infected on ART. Comparisons used χ(2) test, t test, analysis of variance and multiple linear regression. RESULTS No differences were found in ejection fraction, shortening fraction or strain in 73 children not yet on ART, 149 on ART and 77 HIV-uninfected controls. As viral load increased, children had worse circumferential strain. In addition, children receiving ART had better circumferential strain than those not yet on ART. Increased CD4 percentage was associated with better longitudinal strain and farther 6MWT distance. As longitudinal strain worsened, the 6MWT distance decreased. HIV-infected children not yet on ART walked a mean of 25.8 m less than HIV-uninfected children, and HIV-infected children on ART walked 25.9 m less (P = 0.015 comparing 3 groups). CONCLUSIONS HIV-uninfected children performed better on the 6MWT than HIV-infected children. Lower viral load, being on ART, and higher CD4 percentage were associated with better strain measures. Better longitudinal strain was associated with a farther 6MWT distance. Overall, ejection fraction, shortening fraction and strain measures between groups were similar, so cardiac strain did not detect cardiac dysfunction in this young population.

Abstract
IMPORTANCE As perinatally human immunodeficiency virus-infected youth (PHIVY) in the United States grow older and more treatment experienced, clinicians need updated information about the association of age, CD4 cell count, viral load (VL), and antiretroviral (ARV) drug use with risk of opportunistic infections, key clinical events, and mortality to understand patient risks and improve care. OBJECTIVE To examine the incidence or first occurrence during follow-up of key clinical events (including Centers for Disease Control and Prevention stage B [CDC-B] and stage C [CDC-C] events) and mortality among PHIVY stratified by age, CD4 cell count, and VL and ARV status. DESIGN, SETTING, AND PARTICIPANTS Combining data from the Pediatric HIV/AIDS Cohort Study (PHACS) Adolescent Master Protocol and International Maternal Pediatric Adolescent AIDS Clinical Trials (IMPAACT) P1074 multicenter cohort studies (March 2007 through April 2015), we estimated event rates during person-time spent in key strata of age (7-12, 13-17, and 18-30 years), CD4 cell count (<200, 200-499, and ≥500/μL), and a combined measure of VL and ARV status (VL <400 or ≥400 copies/mL; ARV therapy or no ARV therapy). A total of 1562 participants in the PHACS Adolescent Master Protocol and IMPAACT P1074 were eligible, and 1446 PHIVY from 41 ambulatory sites in the 12 US states, including Puerto Rico were enrolled. The dates of analysis were March 2015 through January 2017. MAIN OUTCOMES AND MEASURES Clinical event rates stratified by person-time in age, CD4 cell count, and VL and ARV categories. RESULTS A total of 1446 PHIVY participated in the study (mean [SD] age, 14.6 [4.6] years; 759 female [52.5%]; 953 black [65.9%]). During a mean (SD) follow-up of 4.9 (1.3) years, higher incidences of CDC-B events, CDC-C events, and mortality were observed as participants aged. Older PHIVY (aged 13-17 and 18-30 years) spent more time with a VL of 400 copies/mL or more and with a CD4 cell count of less than 200/µL compared with 7- to 12-year-old participants (30% and 44% vs 22% of person-time with a VL≥400 copies/mL; 5% and 18% vs 2% of person-time with CD4 cell count <200/µL; P < .001 for each comparison). We observed higher rates of CDC-B events, CDC-C events, bacterial infections, and mortality at lower CD4 cell counts, as expected. The mortality rate among older PHIVY was 6 to 12 times that among the general US population. Higher rates of sexually transmitted infections were also observed at lower CD4 cell counts after adjusting for age. CONCLUSIONS AND RELEVANCE Older PHIVY were at increased risk of viremia, immunosuppression, CDC-B events, CDC-C events, and mortality. Interventions to improve ARV therapy adherence and optimize models of care for PHIVY as they age are urgently needed to improve long-term outcomes among PHIVY.

Abstract
The Pediatric HIV/AIDS Cohort Study (PHACS), the largest ongoing longitudinal study of perinatal HIV-infected (PHIV) and HIV-exposed, uninfected (PHEU) children in the United States, comprises the Surveillance Monitoring of Antiretroviral Therapy [ART] Toxicities (SMARTT) Study in PHEU children and the Adolescent Master Protocol (AMP) that includes PHIV and PHEU children ≥7 years. Although race/ethnicity is often used to assess health outcomes, this approach remains controversial and may fail to accurately reflect the backgrounds of ancestry-diverse populations as represented in the PHACS participants.In this study, we compared genetically determined ancestry (GDA) and self-reported race/ethnicity (SRR) in the PHACS cohort. GDA was estimated using a highly discriminative panel of 41 single nucleotide polymorphisms and compared to SRR. Because SRR was similar between the PHIV and PHEU, and between the AMP and SMARTT cohorts, data for all unique 1958 participants were combined.According to SRR, 63% of study participants identified as Black/African-American, 27% White, and 34% Hispanic. Using the highest percentage of ancestry/ethnicity to identify GDA, 9.5% of subjects were placed in the incorrect superpopulation based on SRR. When ≥50% or ≥75% GDA of a given superpopulation was required, 12% and 25%, respectively, of subjects were placed in the incorrect superpopulation based on SRR, and the percent of subjects classified as multiracial increased. Of 126 participants with unidentified SRR, 71% were genetically identified as Eurasian.GDA provides a more robust assessment of race/ethnicity when compared to self-report, and study participants with unidentified SRR could be assigned GDA using genetic markers. In addition, identification of continental ancestry removes the taxonomic identification of race as a variable when identifying risk for clinical outcomes.

Abstract
Antiretroviral (ARV) drug therapy, given during pregnancy for prevention of mother-to-child transmission of human immunodeficiency virus 1 (HIV-1), induces fetal mitochondrial dysfunction in some children. However, the persistence/reversibility of that dysfunction is unclear. Here we have followed Erythrocebus patas (patas) monkey offspring for up to 3 years of age (similar in development to a 15-year old human) after exposure of the dams to human-equivalent in utero ARV exposure protocols. Pregnant patas dams (3-5/exposure group) were given ARV drug combinations that included zidovudine (AZT)/lamivudine (3TC)/abacavir (ABC), or AZT/3TC/nevirapine (NVP), for the last 10 weeks (50%) of gestation. Infants kept for 1 and 3 years also received drug for the first 6 weeks of life. In offpsring at birth, 1 and 3 years of age mitochondrial morphology, examined by electron microscopy (EM), was compromised compared to the unexposed controls. Mitochondrial DNA (mtDNA), measured by hybrid capture chemiluminescence assay (HCCA) was depleted in hearts of patas exposed to AZT/3TC/NVP at all ages (P < 0.05), but not in those exposed to AZT/3TC/ABC at any age. Compared to unexposed controls, mitochondrial reserve capacity oxygen consumption rate (OCR by Seahorse) in cultured bone marrow mesenchymal fibroblasts from 3-year-old patas offspring was ∼50% reduced in AZT/3TC/ABC-exposed patas (P < 0.01), but not in AZT/3TC/NVP-exposed patas. Overall the data show that 3-year-old patas sustain persistent mitochondrial dysfunction as a result of perinatal ARV drug exposure. Environ. Mol.

Abstract
Pediatric human immunodeficiency virus (HIV-1) infection remains a global health crisis. Children are much more susceptible to HIV-1 neurological impairments than adults, which can be exacerbated by coinfections. Neurological characteristics of pediatric HIV-1 infection suggest dysfunction in the frontal cortex as well as the hippocampus; limited MRI data indicate global cerebral atrophy, and pathological data suggest accelerated neuronal apoptosis in the cortex. An obstacle to pediatric HIV-1 research is a human representative model system. Host-species specificity of HIV-1 limits the ability to model neurological consequences of pediatric HIV-1 infection in animals. Several models have been proposed including neonatal intracranial injections of HIV-1 viral proteins in rats and perinatal simian immunodeficiency virus (SIV) infection of infant macaques. Nonhuman primate models recapitulate the complexity of pediatric HIV-1 neuropathogenesis while rodent models are able to elucidate the role specific viral proteins exert on neurodevelopment. Nonhuman primate models show similar behavioral and neuropathological characteristics to pediatric HIV-1 infection and offer a stage to investigate early viral mechanisms, latency reservoirs, and therapeutic interventions. Here we review the relative strengths and limitations of pediatric HIV-1 model systems.

Abstract
The availability of highly potent antiretroviral treatment during the last decades has transformed human immunodeficiency virus (HIV) infection into a chronic disease. Children that were diagnosed during the first months or years of life and received treatment, are living longer and better and are presently reaching adolescence and adulthood. Perinatally HIV-infected adolescents (PHIV) and young adults may present specific clinical, behavior and social characteristics and demands. We have performed a literature review about different aspects that have to be considered in the care and follow-up of PHIV. The search included papers in the MEDLINE database via PubMed, located using the keywords “perinatally HIV-infected” AND “adolescents”. Only articles published in English or Portuguese from 2003 to 2014 were selected. The types of articles included original research, systematic reviews, and quantitative or qualitative studies; case reports and case series were excluded. Results are presented in the following topics: “Puberal development and sexual maturation”, “Growth in weight and height”, “Bone metabolism during adolescence”, “Metabolic complications”, “Brain development, cognition and mental health”, “Reproductive health”, “Viral drug resistance” and “Transition to adult outpatient care”.

Abstract
PURPOSE OF REVIEW Here we present fetal genotoxicity and mitochondrial toxicity, induced by nucleoside reverse transcriptase inhibitors (NRTIs), in HIV-1-infected pregnant women treated to prevent mother-to-child HIV-1 transmission, and in virus-free pregnant patas monkeys. RECENT FINDINGS In the offspring of pregnant patas monkeys given human-equivalent NRTI protocols, aneuploidy was found in cultured bone marrow cells taken at birth, 1, and 3 years of age. In some newborn human infants, the offspring of HIV-1-infected mothers given zidovudine (AZT) therapy, aneuploidy, mitochondrial DNA (mtDNA) depletion, morphologically damaged mitochondria, and reduction in cardiac left ventricular muscle were observed. NRTI-exposed human and patas umbilical cords had similar levels of mtDNA depletion and mitochondrial morphological damage. NRTI-exposed patas offspring showed a compensatory increase in heart mtDNA, and a 50% loss of brain mtDNA at 1 year of age. Mitochondrial morphological damage and mtDNA loss were persistent in blood cells of NRTI-exposed infants up to 2 years of age, and in heart and brain from NRTI-exposed patas up to 3 years of age (human equivalent of 15 years). SUMMARY Whereas use of NRTIs in human pregnancy protects many thousands of children worldwide, some HIV-1-uninfected infants born to HIV-1-infected mothers receiving antiretroviral drug therapy sustain toxicities that may have adverse consequences later in life.

Abstract
BACKGROUND HIV infection in children is now considered as a chronic condition, in which various non-infectious complications may occur, including those affecting the developing cardiovascular system. As children are expected to survive well into adulthood, understanding childhood as well as potential future cardiovascular complications is of major importance. METHODS AND RESULTS We reviewed published literature on childhood cardiac manifestations and longer term effects of pediatric HIV infection on the cardiovascular system. Evidence gaps that should be prioritized in research are highlighted. Through poorly understood mechanisms, HIV infection may cause various cardiac complications already manifesting in childhood, such as structural and functional myocardial derangements, pulmonary hypertension, pericardial effusion and possibly endocarditis. Evidence indicates that HIV infection in children also has unfavorable effects on the vasculature and cardiovascular biomarkers, such as increased intima-media thickness and decreased flow-mediated dilation, a marker of endothelial function. However, studies are small and predominantly include antiretroviral therapy-treated children, so that it is difficult to differentiate between effects of HIV infection per se and antiretroviral therapy treatment, reported in adults to have cardiovascular side effects. CONCLUSIONS HIV infection in children may greatly impact the cardiovascular system, including effects on the heart, which tend to manifest early in childhood, and on the vasculature. The underlying mechanisms, essential for targeted prevention, are poorly understood. Current evidence largely stems from research in adults. However, as modes of infection, immune maturity, growth and development, and treatment are markedly different in children, specific pediatric research, accounting for the complex interplay of normal growth and development, HIV infection and treatment, is clearly warranted.

Abstract
Human immunodeficiency virus (HIV) infection causes dysfunction of different organ systems. Myocardial diastolic dysfunction has been reported previously in an adult HIV population. Our aim was to study myocardial strain in children and young adults infected by HIV who have apparently normal ejection fraction. Forty HIV-infected patients (mean age 20.6 ± 1.5 years) with normal ejection fraction and 55 matched normal controls (mean age 17 ± 1.5 years) were studied by two-dimensional echocardiogram. The images were stored then exported to velocity vector imaging software for analysis. Measures considered were left-ventricular peak global systolic strain (LV S) and strain rate (LV SR) as well as right-ventricular peak global systolic strain (RV S) and strain rate (RV SR). Circumferential measures of the left ventricle included the following: LV circumferential peak global systolic strain (LV circ S), strain rate (LV circ SR), radial velocity (LV rad vel), and rotational velocity (LV rot vel) at the level of the mitral valve. Statistical significance was set at p < 0.05. The means of all longitudinal deformation parameters were significantly lower in HIV patients compared with normal controls: LV S (-14.15 vs. -19.31), LV SR (-0.88 vs. -1.30), RV S (-19.58 vs. -25.09), and RV SR (-1.34 vs. -2.13), respectively (p < 0.05). LV rot vel was lower in patients compared with controls (43.23 vs. 51.71, p = 0.025). LV circ S, LV circ SR, and LV rad vel showed no significant difference between the two groups (p ≥ 0.05). HIV infection affects longitudinal systolic cardiac strain and strain rate in children and young adults. Normal ejection fraction might be attributed to preserved circumferential myocardial deformation. Strain and strain rate may help identify HIV patients at high risk for cardiac dysfunction and allow early detection of silent myocardial depression.

Abstract
Worldwide, more than three million children are infected with HIV, 90% of whom live in sub-Saharan Africa. As the HIV epidemic matures and antiretroviral treatment is scaled up, children with HIV are reaching adolescence in large numbers. The growing population of adolescents with perinatally acquired HIV infection living within this region presents not only unprecedented challenges but also opportunities to learn about the pathogenesis of HIV infection. In this Review, we discuss the changing epidemiology of paediatric HIV and the particular features of HIV infection in adolescents in sub-Saharan Africa. Longstanding HIV infection acquired when the immune system is not developed results in distinctive chronic clinical complications that cause severe morbidity. As well as dealing with chronic illness, HIV-infected adolescents have to confront psychosocial issues, maintain adherence to drugs, and learn to negotiate sexual relationships, while undergoing rapid physical and psychological development. Context-specific strategies for early identification of HIV infection in children and prompt linkage to care need to be developed. Clinical HIV care should integrate age-appropriate sexual and reproductive health and psychological, educational, and social services. Health-care workers will need to be trained to recognise and manage the needs of these young people so that the increasing numbers of children surviving to adolescence can access quality care beyond specialist services at low-level health-care facilities.

Abstract
The great success in the prevention and treatment of pediatric HIV in high resource countries, and now in low resource countries, has changed the face of the HIV epidemic in children from one of near certain mortality to that of a chronic disease. However, these successes pose new challenges as perinatally HIV-infected youth survive into adulthood. Increased survival of HIV-infected children is associated with challenges in maintaining adherence to what is likely life-long therapy, and in selecting successive antiretroviral drug regimens, given the limited availability of pediatric formulations, limitations in pharmacokinetic and safety data of drugs in children, and the development of extensive drug resistance in multi-drug-experienced children. Pediatric HIV care must now focus on morbidity related to long-term HIV infection and its treatment. Survival into adulthood of perinatally HIV-infected youth in high resource countries provides important lessons about how the epidemic will change with increasing access to antiretroviral therapy for children in low resource countries. This series of papers will focus on issues related to management of perinatally infected youth and young adults.
