Abstract
OBJECTIVES Children with perinatally acquired HIV (PHIV) and taking antiretroviral therapy (ART) have a high prevalence of subclinical cardiac disease. We hypothesized that cardiac disease may be a consequence of dysregulated systemic immune activation driven by HIV infection. We examined cardiovascular and proinflammatory biomarkers and their association with echocardiographic abnormalities in children with PHIV. DESIGN Cross-sectional analysis of soluble biomarkers from a prospective cohort of children aged 6-16 years with PHIV and age-matched HIV-uninfected comparison group. METHODS Cryopreserved plasma samples were used to measure seven soluble biomarkers using multiplex bead assay (Luminex). Multivariable logistic regression assessed how biomarker levels related to cardiac abnormalities. RESULTS A total of 406 children participated in this study (195 PHIV and 211 HIV-uninfected). Mean [standard deviation (SD)] ages of PHIV and HIV-uninfected participants were 10.7 (2.6) and 10.8 (2.8) years, respectively. Plasma levels of CRP, TNF-α, ST2, VCAM-1 and GDF-15 were significantly higher in the PHIV group compared with uninfected control ( P < 0.001). Among children with PHIV, with one-unit representing one SD in biomarker level, a one-unit increase in CRP and GDF-15, was associated with increased odds of having left ventricular (LV) diastolic dysfunction [adjusted odds ratio (aOR), 1.49 (1.02-2.18; P < 0.040)] and [aOR 1.71 (1.18-2.53; P = 0.006)], respectively. Each one unit increase in GDF-15 was associated with increased odds of LV hypertrophy [aOR 1.84 (95% CI 1.10-3.10; P < 0.021)]. CONCLUSION Children with PHIV had higher levels of proinflammatory and cardiovascular biomarkers compared with HIV-uninfected children. Increased CRP and GDF-15 were associated with cardiac abnormalities in children with PHIV.

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
OBJECTIVES Up to one third of children with heart failure exhibit growth failure. Limited data exists reporting energy requirements in this population. A study was designed to characterize the energy intake and total daily energy expenditure of children with heart failure using the doubly labeled water method. DESIGN Prospective study using doubly labeled water to measure total daily energy expenditure in children with heart failure. Doubly labeled water was administered orally and daily urine samples collected for 10 days. Total daily energy expenditure was compared with historic data from age- and gender-matched healthy population. Anthropometrics and 3-day calorie count were also done. SETTING The Cardiovascular Intensive Care Unit and Cardiology ward at Texas Children's Hospital. PATIENTS Children with new presentation of heart failure as defined by an ejection fraction less than 35% and requiring inotrope(s) at the time of enrollment. MEASUREMENTS AND MAIN RESULTS A total of five children with heart failure were enrolled from 2015 to 2016. All children showed weight-for-length less than mean-for-age. All had depressed myocardial function at enrollment, and all but one demonstrated improvement in ejection fraction at follow-up. Three had energy intake that met or surpassed their total daily energy expenditure, with total daily energy expenditure that measured below historic controls. One infant, despite supplementation, had an energy intake substantially below that of measured total daily energy expenditure and required cardiac transplantation. CONCLUSIONS Growth failure in heart failure is likely multifactorial and may be related to suboptimal energy intake secondary to exercise intolerance, malabsorption, and/or end-organ dysfunction due to impaired cardiac output. Doubly labeled water is a feasible method to assess total daily energy expenditure in children with heart failure.

Abstract
OBJECTIVES To compare distributions of serum cardiac and inflammatory biomarkers between perinatally HIV-infected (PHIV) and perinatally HIV-exposed uninfected (PHEU) children, to evaluate their associations with echocardiographic measures, and among PHIV youth, with antiretroviral therapy (ART) and HIV disease severity measures. DESIGN Cross-sectional analysis of temporally paired serum samples for biomarkers and echocardiograms in a prospective multicenter cohort study of PHIV and PHEU youth. METHODS Serum samples were analyzed among 402 youth in the PHACS Adolescent Master Protocol (AMP) for high-sensitivity cardiac troponin-T (hs-cTnT, a cardiomyocyte injury marker), N-terminal-pro-brain natriuretic peptide (NT-proBNP, a myocardial stress marker), and inflammatory markers [high-sensitivity C-reactive protein, interleukin (IL)-1, IL-6, IL-8, IL-10, IL-18, tumor necrosis factor-α (TNF-α), and soluble TNF receptor II (sTNF-RII)]. Echocardiograms were centrally measured and parameters converted to z cores to account for differences in age and body size. RESULTS Compared with PHEU (N = 156), PHIV youth (N = 246) more often had detectable hs-cTnT and higher levels of sTNF-RII and IL-18. Higher inflammatory biomarkers were generally associated with higher left ventricular (LV) wall stress and lower LV function and LV mass in the two groups. Among PHIV youth, the biomarkers were more strongly associated with current rather than historical immunologic and virologic status. CONCLUSION PHEU and PHIV have modest, significant differences in serum levels of specific inflammatory and active myocardial injury biomarkers. Higher biomarker levels were associated with lower LV mass and shifts in LV structure. Further study is warranted on the longitudinal role of cardiac and inflammatory biomarkers for targeting interventions among PHIV and PHEU youth.

Abstract
Introduction: Cardiac complications of HIV infection tend to occur late in the disease or are associated with related therapies and are therefore becoming more prevalent as therapy and longevity improve. Materials and Methods: The study was undertaken to study the common cardiovascular complications in Indian HIV patients and to their association with the CD4+ T-cell count. Observations and Conclusion: Prevalence of cardiac abnormality in our study was 24%. The abnormalities included LVDD (22%), pulmonary hypertension (12%), DCMP (12%), pericardial effusion (7%), left ventricular systolic dysfunction (5%), and right ventricular dysfunction (1%).

Abstract
BACKGROUND Before the introduction of highly active antiretroviral therapy (HAART), cardiac mortality and morbidity were common in HIV-infected children. OBJECTIVES This study sought to identify long-term cardiovascular effects of HAART in HIV-infected children. METHODS The CHAART-2 (HAART-Associated Cardiotoxicity in HIV-Infected Children) study prospectively compared 148 echocardiograms from 74 HAART-exposed children to 860 echocardiograms from 140 HAART-unexposed but HIV-infected children from the Pulmonary and Cardiac Complications of Vertically Transmitted HIV Infection (P2C2 HIV) study. Both studies used similar protocol, centralized echocardiographic interpretation, and measures expressed as z-scores referenced to healthy controls. Associations between HAART exposure and echocardiographic measures were evaluated using generalized estimating equations. RESULTS Comparing the HAART-exposed and HAART-unexposed groups, any HAART exposure was positively associated with left ventricular (LV) fractional shortening (z-score for difference = 1.07; p = 0.02) and HAART exposure duration (z-score difference per year = 0.17; p = 0.003. LV mass was negatively associated with any HAART exposure (z-score difference = -0.64; p = 0.01) as was septal thickness (z-score difference = -0.93; p = 0.001). Duration of HAART exposure was negatively associated with LV end-systolic dimension and heart rate (z-score difference per year= -0.11; p = 0.05; and z-score difference per year = -0.10; p = 0.002, respectively). During 11 years of follow-up, in the HAART-exposed group, LV mass and LV end-diastolic septal thickness were lower whereas LV contractility and LV fractional shortening were higher when compared to the HAART-unexposed group. CONCLUSIONS Cardiac structure and function were better in perinatally HIV-infected children exposed to HAART than in those of similar children from the pre-HAART era but did decline over time. Evidence-based strategies for cardiovascular monitoring are needed to inform treatment decisions to improve long-term cardiovascular health.

Abstract
BACKGROUND Despite effective antiretroviral therapy (ART), HIV-infected children on treatment have been observed to have cardiac abnormalities. We sought to determine the prevalence, types and factors associated with cardiac abnormalities among HIV-infected Ugandan children on combination ART. METHODS We carried out a cross-sectional study from July 2012 to January 2013, at Joint Clinical Research Centre among HIV-infected children aged 1-18 years. Cardiac abnormalities were assessed using electrocardiography and echocardiography. CD4 counts, viral load and complete blood count were performed at enrollment. The prevalence of cardiac abnormalities was determined using simple proportions with the associated factors ascertained using logistic regression. RESULTS Among 285 children recruited, the median (interquartile range) age was 9 (6-13) years, 54% were female; 72% were on first line combination ART. Their mean (±SD) CD4 count was 1092 (±868.7) cells/mm; median (interquartile range) viral load was 20 (20-76) copies/mL. Ninety-four percent had adherence to ART of more than 95%. Cardiac abnormalities were detected in 39 (13.7%) children. The most common abnormalities by electrocardiography and echocardiography were nonspecific T wave changes (4.6%) and pericardial disease (thickened pericardium with or without pericardial effusion; 2.8%), respectively. No factor assessed was found to be significantly associated occurrence of cardiac dysfunction. CONCLUSIONS The prevalence of cardiac dysfunction among the HIV-infected children on ART was 13.7%, which was high, with nonspecific T wave changes and pericardial disease being the most frequent abnormalities observed. No factor assessed was found to be associated with cardiac dysfunction.

Abstract
BACKGROUND Cardiovascular dysfunction is a recognized complication of HIV infection in children. Cardiac complications of HIV usually occur late in the course of the disease; they may be associated with drug therapy, and hence become more common as therapy and survival improve. Left ventricular (LV) dysfunction at baseline is a risk factor for death independent of the CD4 cell count, HIV viral load, and neurological disease. CLINICAL CASE We present the case of a 15 year old girl with HIV who developed left ventricular dysfunction while non-compliant on highly active antiretroviral therapy (HAART). She presented with features of heart failure over a course of two months. Her laboratory evaluation was significant for leucopenia with a low CD4 count, high viral load, elevated ESR and CRP. The ECG showed a sinus tachycardia with diffuse ST-T segment changes and LVH with strain. Initial echo revealed dilated left heart chambers with poor LV systolic function and a small pericardial effusion with the development of an LV thrombus on follow up echo evaluation. She was started on heart failure medicines and had anticoagulation for the LV thrombus. She received adherence counseling and her HAART regimen was changed. Six months after presentation she became asymptomatic with higher CD4 counts and a normal LV size and function on echo. CONCLUSION Immunological recovery following a switch of a failing or potentially cardiotoxic HAART in addition to improved HAART adherence may result in resolution of left ventricular dysfunction. Early and regular cardiology evaluation may improve outcomes in these patients.

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
IMPORTANCE Prior to contemporary antiretroviral therapies (ARTs), children infected with human immunodeficiency virus (HIV) were more likely to have heart failure. This study suggests that highly active ART (HAART) does not appear to impair heart function. OBJECTIVE To determine the cardiac effects of prolonged exposure to HAART on HIV-infected children. DESIGN In the National Institutes of Health-funded Pediatric HIV/AIDS Cohort Study's Adolescent Master Protocol (AMP), we used linear regression models to compare echocardiographic measures. SETTING A total of 14 US pediatric HIV clinics. PARTICIPANTS Perinatally HIV-infected children receiving HAART (n = 325), HIV-exposed but uninfected children (n = 189), and HIV-infected (mostly HAART-unexposed) historical pediatric controls from the National Institutes of Health-funded Pulmonary and Cardiovascular Complications of Vertically Transmitted HIV Infection (P2C2-HIV) Study (n = 70). EXPOSURE Long-term HAART. MAIN OUTCOMES AND MEASURES Echocardiographic measures of left ventricular (LV) function and structure. RESULTS The 325 AMP HIV-infected children had lower viral loads, higher CD4 counts, and longer durations of ART than did the 70 HIV-infected children from the P2C2-HIV Study (all P < .001). The z scores for LV fractional shortening (a measure of cardiac function) were significantly lower among HIV-infected children from the P2C2-HIV Study than among the AMP HIV-infected group or the 189 AMP HIV-exposed but uninfected controls (P < .05). For HIV-infected children, a lower nadir CD4 percentage and a higher current viral load were associated with significantly lower cardiac function (LV contractility and LV fractional shortening z scores; all P = .001) and an increased LV end-systolic dimension z score (all P < .03). In an interaction analysis by HIV-infected cohort, the HIV-infected children from the P2C2-HIV Study with a longer ART exposure or a lower nadir CD4 percentage had lower mean LV fractional shortening z scores, whereas the mean z scores were relatively constant among AMP HIV-infected children (P < .05 for all interactions). CONCLUSIONS AND RELEVANCE Long-term HAART appears to be cardioprotective for HIV-infected children and adolescents.

Abstract
OBJECTIVE Previous studies of cardiomyopathy among children perinatally infected with HIV were conducted before the routine use of HAART. Nucleoside analogs [nucleoside reverse transcriptase inhibitors (NRTIs)], the backbone of HAART, have been associated with mitochondrial toxicity, which can lead to cardiomyopathy. We evaluated the association of HAART and specific NRTIs associated with mitochondrial toxicity, on development of cardiomyopathy among perinatally HIV-infected children. DESIGN Three thousand and thirty-five perinatally HIV-infected children enrolled in a US-based multicenter prospective cohort study were followed for cardiomyopathy, defined as a clinical diagnosis or initiation of digoxin, from 1993 to 2007. METHODS Cox models were used to estimate the effects of HAART and NRTIs on cardiomyopathy, identify predictors of cardiomyopathy among HAART users, and estimate the association between development of cardiomyopathy and mortality. RESULTS Ninety-nine cases of cardiomyopathy were identified over follow-up (incidence rate: 5.6 cases per 1000 person-years) at a median age of 9.4 years. HAART was associated with a 50% lower incidence of cardiomyopathy compared with no HAART use (95% confidence interval: 20%, 70%). Zalcitabine (ddC) use, however, was associated with an 80% higher incidence of cardiomyopathy. Among HAART users, older age at HAART initiation, ddC use before HAART initiation, initiating a HAART regimen containing zidovudine (ZDV), and a nadir CD4 percentage less than 15% were independently associated with a higher rate of cardiomyopathy. Cardiomyopathy was associated with a six-fold higher mortality rate. CONCLUSION HAART has dramatically decreased the incidence of cardiomyopathy among perinatally HIV-infected children. However, they remain at increased risk for cardiomyopathy and ongoing ZDV exposure may increase this risk.

Abstract
OBJECTIVE Abnormalities in left ventricular morphology and function have been reported in HIV-negative infants exposed to antiretroviral therapy (ART) in utero that persists throughout preschool age. The objective of this study was to determine if these abnormalities persist, resolve, or worsen during preadolescence. DESIGN Cross-sectional observation study. METHODS Thirty HIV-negative children born to HIV-positive women and exposed to ART in utero (mean age 8 ± 2 years, 37% female, 74% African-American) and 30 HIV-negative children born to HIV-negative women (mean age 8 ± 3 years, 37% female, 76% African-American) underwent two-dimensional Doppler, tissue Doppler, and strain echocardiography to evaluate left ventricular systolic and diastolic function. RESULTS Weight, body surface area, heart rate and blood pressure were similar between groups. For the ART-exposed group, left ventricular mass index was lower (60 ± 9 vs. 67 ± 12 g/m, P < 0.02) and early diastolic annular velocity was lower (15.0 ± 2.2 vs. 16.3 ± 2.5 cm/s, P < 0.03) compared to controls. Left ventricular systolic function did not differ between groups. Lower maternal third trimester CD4 count was associated with lower early diastolic annular velocity; other non-HIV-related variables including cocaine use and increased maternal age correlated with lower left ventricular mass index. CONCLUSIONS Abnormalities in left ventricular systolic performance previously reported in HIV-negative infants and preschool aged children exposed to ART in utero were not apparent in preadolescent children. Left ventricular diastolic relaxation was reduced compared with controls suggesting residual effects of ART exposure on left ventricular diastolic function. Larger, longitudinal studies are necessary to confirm these observations.

Abstract
OBJECTIVE To analyse the outcome of children with left ventricular dysfunction placed on Highly Active Antiretroviral Therapy. METHOD This study is a retrospective review of records of Human Immunodeficiency Virus-positive children with left ventricular dysfunction. Demographic data were collected. Left ventricular fractional shortening, CD4 percentage, viral load, and nutritional status were compared before and during antiretroviral therapy. RESULTS We reviewed the records of 34 Human Immunodeficiency Virus-positive children with left ventricular dysfunction. In all, 18 patients received antiretroviral therapy (group one) and 16 were antiretroviral therapy naive (group two). The median age of group one at initial visit was 94 months, with a male-to-female ratio of 1:1. Of those, 17 children showed improved left ventricular function on treatment, with an increase in fractional shortening (median: 17-33.5%; p less than 0.0001). There was no significant statistical difference between the groups regarding initial fractional shortening. In group one, the CD4 percentage improved (median: 12% to 30.5%; p less than 0.0001), with viral load suppression (median: 24,900 copies per millilitre to less than 25 copies per millilitre; p less than 0.0001). There was weight gain in group one (median z-score: -1.70 to -1.32; p equal to 0.0083). Proper statistical analysis in group two was not possible because of poor follow-up of patients. CONCLUSION The findings are in keeping with other reports that have shown improvement in left ventricular function in patients with Human Immunodeficiency Virus-associated cardiomyopathy treated with Highly Active Antiretroviral Therapy. Recovery of myocardial function is associated with improvement in immunological and nutritional statuses.

Abstract
OBJECTIVE To investigate the prevalence, profile and predictors of severe malnutrition in children with congenital heart defects (CHDs). DESIGN Case-control, observational study. SETTING Tertiary teaching hospital in Lagos, Nigeria (March 2006 to March 2008). PARTICIPANTS Children aged 3-192 months with uncorrected symptomatic CHD and healthy controls, frequency matched for age and sex. MAIN OUTCOME MEASURES Prevalence of malnutrition based on WHO/National Center for Health Statistics/Centers for Disease Control and Prevention z score ≤-2; weight for age, weight for height/length and height for age; proportions of underweight, wasting and stunting in cases and controls, and in acyanotic and cyanotic CHD; and predictors of malnutrition using multivariate logistic analysis. RESULTS 90.4% of cases and 21.1% of controls had malnutrition (p=0.0001), and 61.2% and 2.6%, respectively, had severe malnutrition (p=0.0001). Wasting, stunting and underweight were identified in 41.1%, 28.8% and 20.5%, and 2.6%, 3.9% and 14.5% of cases and controls, respectively. Wasting was significantly higher (58.3%) in acyanotic CHD (p=0.0001), and stunting (68.0%) in cyanotic CHD (p=0.0001). Age at weaning was significantly lower in cases than controls (3.24±0.88 and 7.04±3.04 months, respectively; p=0.0001) and in acyanotic than cyanotic CHD (2.14±0.33 and 5.33±1.22 months, respectively; p=0.004). Predictors of malnutrition in CHD were anaemia, moderate to severe congestive heart failure (CHF), poor dietary intake of fat and prolonged unoperated disease. CONCLUSION Severe malnutrition in association with anaemia and moderate to severe CHF is highly prevalent in CHD preoperatively in these children. Early weaning may be a marker of feeding difficulties in heart failure.

Abstract
OBJECTIVES The aim of this study was to investigate the possible effects of antiretroviral therapy (ART) in utero on cardiac development and function in human immunodeficiency virus (HIV)-negative children. BACKGROUND ART reduces vertical HIV transmission. Long-term cardiotoxicity after in utero exposure to ART is unknown in children but has occurred in young animals. METHODS Using a prospective multisite cohort study design, echocardiograms taken between birth and 24 months were compared in 2 groups of HIV-negative infants of HIV-positive mothers: 136 infants exposed to ART (ART+) and 216 unexposed infants (ART-). RESULTS Mean left ventricular (LV) mass z-scores were consistently lower in ART+ girls than in ART- girls: differences in mean z-scores were -0.46 at birth (p = 0.005), -1.02 at 6 months (p < 0.001), -0.74 at 12 months (p < 0.001), and -0.79 at 24 months (p < 0.001). Corresponding differences in z-scores for boys were smaller: 0.13 at 1 month (p = 0.42), -0.44 at 6 months (p = 0.01), -0.15 at 12 months (p = 0.37), and -0.21 at 24 months (p = 0.21). Septal wall thickness and LV dimension were smaller than expected in ART+ infants, but LV contractility was consistently about 1 SD higher at all ages (p < 0.001). In ART+ infants, LV fractional shortening was higher than in ART- infants; girls showed a greater difference. CONCLUSIONS Fetal exposure to ART is associated with reduced LV mass, LV dimension, and septal wall thickness z-scores and increased LV fractional shortening and contractility up to age 2 years. These effects are more pronounced in girls than in boys. Fetal ART exposure may impair myocardial growth while improving depressed LV function.

Abstract
OBJECTIVES To assess the importance of anemia in HIV-infected children in western and tropical settings. DESIGN A systematic review with a descriptive component. METHODS : Four databases were searched and reference lists of pertinent articles were checked. Studies that reported data on anemia or hemoglobin levels in HIV-infected children were selected and grouped according to the location and the definition of anemia. RESULTS Thirty-six studies met the inclusion criteria. Mild (hemoglobin <11 g/dl) and moderate (hemoglobin <9 g/dl) anemia were more prevalent with HIV infection (odds ratio 4.5; 95% confidence interval 2.5-8.3 and odds ratio 4.5; 95% confidence interval 2.0-10.3, respectively). Mean hemoglobin levels were lower (standardized mean difference; 0.79; 95% confidence interval 0.47-1.10). These differences were observed in both western and tropical settings. Anemia incidence ranged from 0.41 to 0.44 per person-year. There was limited data on more severe anemia (hemoglobin <7 or <5 g/dl). As anemia was frequently identified as an independent risk factor for disease progression and death, we next reviewed the limited data to formulate better strategies. Failure of erythropoiesis was the most important mechanism for anemia in HIV-infected children. Therapeutic options include highly active antiretroviral therapy and prevention or treatment of secondary infections. Erythropoietin can improve anemia in children, but it has not been evaluated in developing countries. Micronutrient supplementation may be helpful in individual children. The potential benefits or risks of iron supplementation in HIV-infected children require evaluation. CONCLUSION Anemia is a very common complication of pediatric HIV infection, associated with a poor prognosis. With the increasing global availability of highly active antiretroviral therapy, more data on the safety and efficacy of possible interventions in children are urgently needed.

Abstract
OBJECTIVE We investigated the effect of short viremic episodes on soluble markers associated with endothelial stress and cardiovascular disease risk in chronically HIV-1-infected patients followed during continuous antiretroviral therapy, antiretroviral therapy interruption and antiretroviral therapy resumption. DESIGN AND METHODS We assessed changes in plasma levels of von Willebrand factor, soluble vascular cell adhesion molecule-1 and intercellular adhesion molecule-1 by enzyme-linked immunosorbent assay, as well as T-cell activation (CD8+/CD38+, CD8+/HLA-DR+ and CD3+/CD95+) by flow cytometry, in 36 chronically HIV-1-infected patients participating in a randomized study. Patients were divided into the following three groups: a, on continuous antiretroviral therapy; b, on a 6-week antiretroviral therapy interruption; or c, on antiretroviral therapy interruption extended to the achievement of viral set point. RESULTS Although all measurements remained stable over a 40-week follow-up on antiretroviral therapy, plasma levels of soluble vascular cell adhesion molecule-1 (P < 0.0001) and soluble intercellular adhesion molecule-1 (P = 0.003) increased during treatment interruption in correlation with viral rebound and T-cell activation. No significant changes in von Willebrand factor were observed in any of the groups. After resuming antiretroviral therapy, soluble vascular cell adhesion molecule-1 levels remained elevated even after achievement of viral suppression to less than 50 copies/ml. CONCLUSION The prompt rise in plasma soluble vascular cell adhesion molecule-1 and soluble intercellular adhesion molecule-1 upon viral rebound suggests an acute increase in endothelial stress upon treatment interruption, which may persists after viral resuppression of virus. Thus, viral replication during short-term treatment interruption may increase the overall cardiovascular risk during and beyond treatment interruption.

Abstract
Pediatric cardiomyopathies are heterogeneous groups of serious disorders of the heart muscle and are responsible for significant morbidity and mortality among children who have the disease. While enormous improvements have been made in the treatment and survival of children with congenital heart disease, parallel strides have not been made in the outcomes for cardiomyopathies. Thus, ancillary therapies, such as nutrition and nutritional interventions, that may not cure but may potentially improve cardiac function and quality of life, are imperative to consider in children with all types of cardiomyopathy. Growth failure is one of the most significant clinical problems of children with cardiomyopathy with nearly one-third of children with this disorder manifesting some degree of growth failure during the course of their illness. Optimal intake of macronutrients can help improve cardiac function. In addition, several specific nutrients have been shown to correct myocardial abnormalities that often occur with cardiomyopathy and heart failure. In particular, antioxidants that can protect against free radical damage that often occurs in heart failure and nutrients that augment myocardial energy production are important therapies that have been explored more in adults with cardiomyopathy than in the pediatric population. Future research directions should pay particular attention to the effect of overall nutrition and specific nutritional therapies on clinical outcomes and quality of life in children with pediatric cardiomyopathy.

Abstract
This study investigated the possible role of the cardiac isoform of alpha 2-macroglobulin (CA2M) as an early diagnostic marker for HIV-associated cardiovascular manifestations. A total of 349 samples were analysed by Western blot and quantified by sandwich enzyme-linked immunosorbent assay. The levels of CA2M present in sera of HIV-associated cardiac diseases were significantly higher than those of HIV without cardiac involvement and healthy sera. CA2M may act as a novel diagnostic marker to identify cardiac manifestations in HIV/AIDS patients.

Abstract
The heart and great vessels are not the sites most frequently affected by opportunistic infections and neoplastic processes in patients with acquired immune deficiency syndrome (AIDS). However, cardiovascular complications occur in a significant number of such patients and are the immediate cause of death in some. The spectrum of cardiovascular complications of AIDS that may be depicted at imaging includes dilated cardiomyopathy, pericardial effusion, human immunodeficiency virus-associated pulmonary hypertension, endocarditis, thrombosis, embolism, vasculitis, coronary artery disease, aneurysm, and cardiac involvement in AIDS-related tumors. To aid accurate diagnosis and appropriate treatment planning, radiologists should be familiar with the imaging appearance of each of these complications.

Abstract
Cardiovascular manifestations of HIV vary according to disease stage, treatment regimen and geographical location. Common cardiac complications of HIV disease in patients off highly active antiretroviral therapy (HAART) include dilated cardiomyopathy, myocarditis, pericardial effusion, endocarditis, pulmonary hypertension and non-antiretroviral drug-related cardiotoxicity. However, with the introduction of HAART that has substantially modified the course of HIV disease by lengthening survival, additional cardiovascular consequences are a result of the metabolic syndrome with a propensity toward hyperlipidaemia and atherosclerotic heart disease. Because most of the world's HIV-infected patients have not been treated with HAART, the principal HIV-associated cardiovascular manifestations of patients off HAART are reviewed and new knowledge about the prevalence, pathogenesis and treatment in the HAART era are emphasised in this review. Exercise, a nonpharmacological approach to treating HAART-associated metabolic syndrome, is also discussed.

Abstract
Highly active antiretroviral therapy (HAART) has greatly extended the lives of people infected with the human immunodeficiency virus (HIV). This reduced risk of early death from opportunistic infections or other sequelae of HIV infection, however, means that other possible causes of death emerge. Myocardial infarction has become a matter of particular concern. Two of the main sources of cardiovascular disease in this population are believed to be vascular inflammation and dyslipidemia. We review the evidence for this hypothesis and discuss the relationship of HIV to vascular inflammation. Current treatment guidelines do not recommend the immediate initiation of HAART unless warranted, potentially allowing long-term, unchecked viral impact on the development of atherosclerosis. Finally, we consider the protease inhibitors traditionally included in HAART regimens and their relationship to the development of dyslipidemia, as well as other classes of antiretrovirals, such as the non-nucleoside reverse transcriptase inhibitors, which might be a better choice for patients with cardiovascular risks. Other strategies, such as pharmacologic, nutritional, and physical activity interventions are discussed. The patients who might benefit most are those in whom the precursors of vascular plaques, such as fatty streak, smooth muscle cell, macrophage, and T-lymphocyte aggregation not yet identified by echocardiographic and biopsy findings have already developed as a result of unchecked viral inflammation and replication.

Abstract
BACKGROUND Many HIV-infected children die with cardiac abnormalities. We sought to understand the course of these HIV-associated abnormalities and their impact on all-cause mortality. METHODS We describe longitudinal changes in left ventricular (LV) structure and function and mortality in 185 children vertically infected with HIV. Serial cardiac data were obtained from 0.1 to 10 years of age. Age- or body surface area-adjusted z scores were calculated for 10 echocardiographic outcomes. RESULTS Median age at first echocardiogram was 2 years (range 0.2-9.4 years); median follow-up was 3.6 years (range 0-6.3 years). The 5-year cumulative incidence of congestive heart failure was 12.3%. Mean fractional shortening z scores declined from -0.65 at 1 year of age to -1.47 at 3 years of age without further decline between 3 and 10 years of age. Among children with 2 echocardiograms performed in the first year of follow-up, mild LV dysfunction (fractional shortening of < -2 SD on both echocardiograms) was present in 29 (18%) of 158 children. For these 29 children, the 5-year mortality was 55.4%. Left ventricular mass z scores were elevated at 1 year (mean z score 0.68, P < .001) and remained elevated throughout follow-up. In the 8 children with LV mass z score of > 2 SD on both initial and follow-up echocardiograms, the 5-year mortality was 75%. CONCLUSION In HIV-infected children, LV structure and function progressively deteriorated in the first 3 years of life, resulting in subsequent persistent mild LV dysfunction and increased LV mass. Chronic mild depression of LV function and elevated LV mass were associated with higher all-cause mortality.

Abstract
Cardiac complications contribute significantly to morbidity and mortality in HIV-infected children. There have been few reports of cardiac manifestations in HIV-infected children in developing countries. The aims of this study were to evaluate the clinical manifestations and echocardiographic findings in Thai children with HIV infection and determine the clinical predictors of left ventricular dysfunction and pulmonary hypertension. We retrospectively reviewed the medical records of 27 infants infected with HIV perinatally who presented with cardiovascular problems at a tertiary care hospital between 1995 and 2000. The mean age at initial cardiac evaluation was 36 months (range 8-65). Signs and symptoms included dyspnoea in all cases, oedema in 12 (44%), finger clubbing in 11 (41%), cyanosis in 6 (22%) and S(3) gallop in 8 (30%). Echocardiographic abnormalities included pericardial effusion in 12 (44 %), right ventricular dilatation in 12 (44%), pulmonary hypertension in 11 (41%), diminished left ventricular fractional shortening in 10 (37%), left ventricular dilatation in 9 (33%) and combined ventricular dilatation in 2 (7%). Left ventricular dysfunction did not correlate with HIV CDC classification, age, nutritional status or clinical signs and symptoms.

Abstract
As advances in early diagnosis and aggressive therapy, as well as better supportive care, become available to a larger number of patients with HIV infection, survival is being prolonged, and more patients are experiencing cardiac abnormalities. The most common cardiac manifestations of HIV disease are dilated cardiomyopathy, myocarditis, pericardial effusion, endocarditis, pulmonary hypertension, HIV-associated malignant neoplasms, and drug-related cardiotoxicity. The introduction of highly active antiretroviral therapy (HAART) regimens has substantially modified the course of HIV disease by lengthening survival and improving quality of life of HIV-infected patients. However, early data have raised concerns about HAART being associated with an increase in peripheral and coronary arterial disease. This review discusses the principal HIV-associated cardiovascular manifestations and emphasizes new knowledge about their prevalence, pathogenesis, and treatment.
