de Castro JAC, de Lima TR, Silva DAS. Health-Related Physical Fitness Evaluation in HIV-Diagnosed Children and Adolescents: A Scoping Review. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2024; 21:541. [PMID: 38791753 PMCID: PMC11121308 DOI: 10.3390/ijerph21050541] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/14/2024] [Revised: 04/14/2024] [Accepted: 04/20/2024] [Indexed: 05/26/2024]
Abstract
BACKGROUND Health-related physical fitness has been widely used to investigate the adverse effects of HIV infection/ART in children and adolescents. However, methods/protocols and cut-points applied for investigating health-related physical fitness are not clear. The aim of this scoping review was to map the literature to identify gaps in knowledge regarding the methods/protocols and cut-points. METHODS A scoping review, following the Joana Briggs Institute (JBI) guidelines, was conducted through ten major databases. Search followed the PCC strategy to construct block of terms related to population (children and adolescents), concept (health-related physical fitness components) and context (HIV infection). RESULTS The search resulted in 7545 studies. After duplicate removal, titles and abstracts reading and full text assessment, 246 studies were included in the scoping review. Body composition was the most investigated component (n = 244), followed by muscular strength/endurance (n = 23), cardiorespiratory fitness (n = 15) and flexibility (n = 4). The World Health Organization growth curves, and nationals' surveys were the most reference values applied to classify body composition (n = 149), followed by internal cut-points (n = 30) and cut-points developed through small populations (n = 16). Cardiorespiratory fitness was classified through cut-points from three different assessment batteries, as well as cut-points developed through studies with small populations, muscular strength/endurance and flexibility were classified through the same cut-points from five different assessment batteries. CONCLUSIONS The research on muscular strength/endurance, cardiorespiratory fitness and flexibility has been scarcely explored. The lack of studies that investigated method usability as well as reference values was evidenced.

Adipocytokine dysregulation, abnormal glucose metabolism, and lipodystrophy in HIV-infected adolescents receiving protease inhibitors. Cytokine 2020; 136:155145. [PMID: 32920318 DOI: 10.1016/j.cyto.2020.155145] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2020] [Revised: 04/30/2020] [Accepted: 05/23/2020] [Indexed: 12/28/2022]
Abstract
BACKGROUND Lipodystrophy is common in HIV-infected patients receiving protease inhibitors (PIs), stavudine, and zidovudine. Adipocytokines may be altered in lipodystrophy. We evaluated risk factors, adipocytokine levels, insulin resistance, and lipid profiles in HIV-infected adolescents with different lipodystrophy types. METHODS A cross-sectional study was conducted in 80 perinatally HIV-infected adolescents receiving PI-based highly active antiretroviral therapy for ≥ 6 months. Patients underwent oral glucose tolerance tests and measurements of high-molecular-weight (HMW) adiponectin, leptin, resistin, insulin, and lipids. They were classified into 3 groups based on the clinical findings: no lipodystrophy, isolated lipoatrophy, and any lipohypertrophy (isolated lipohypertrophy or combined type). RESULTS Of the 80 patients (median age, 16.7 years), 18 (22.5%) had isolated lipoatrophy, while 8 (10%) had any lipohypertrophy (four with isolated lipohypertrophy, and four with the combined type). In a multivariate analysis, longer exposure to stavudine (OR: 1.03; 95% CI, 1.01-1.06; p = 0.005) and indinavir (OR: 1.03; 95% CI, 1.01-1.06; p = 0.012) were associated with lipoatrophy, while longer exposure to didanosine (OR: 1.04; 95% CI, 1.01-1.08; p = 0.017) and indinavir (OR: 1.10; 95% CI, 1.00-1.21; p = 0.045) were associated with any lipohypertrophy. Leptin levels were highest in the any-lipohypertrophy group and lowest in the isolated-lipoatrophy group (p = 0.013). HMW adiponectin levels were significantly lowest in the any-lipohypertrophy group and highest in the no-lipodystrophy group (p = 0.001). There were no significant differences in the levels of resistin among the three groups (p = 0.234). The prevalence of insulin resistance (p = 0.002) and prediabetes/diabetes (p < 0.001) were significantly highest in the any-lipohypertrophy group. Patients with lipoatrophy and those without lipodystrophy had comparable degrees of insulin resistance (p = 0.292). In multiple linear regression analysis, adjusted for age, sex, and waist-height ratio, HMW adiponectin levels were associated with Matsuda index (β = 0.5; p = 0.003) and quantitative insulin sensitivity check index (QUICKI) (β = 40.1; p = 0.010) and almost significantly associated with homeostatic model assessment of insulin resistance (HOMA-IR) (p = 0.054). Leptin and resistin levels were not associated with HOMA-IR, Matsuda index, or QUICKI (all p > 0.05). CONCLUSIONS Abnormal glucose metabolism and dysregulation of adipocytokines were common in the HIV-infected adolescents with lipohypertrophy and the combined type. Preventive screening for cardiovascular diseases caused by metabolic alterations should be routinely performed.

Adiponectin, Leptin and Inflammatory Markers in HIV-associated Metabolic Syndrome in Children and Adolescents. Pediatr Infect Dis J 2017; 36:e31-e37. [PMID: 27832021 DOI: 10.1097/inf.0000000000001394] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 02/06/2023]
Abstract
BACKGROUND Metabolic syndrome (MetS) is more common in HIV-infected adults and children than in the general population. Adipocytokines and inflammatory markers may contribute to the pathophysiology of this condition and could be useful indices for monitoring MetS. The objective of this study was to provide information on the prevalence of MetS and investigate the role of adipocytokines and other biomarkers in this syndrome in HIV-infected pediatric patients. METHODS A cross-sectional study was conducted between October 2013 and March 2014 in the outpatient clinics of 2 tertiary pediatric referral hospitals. Fifty-four HIV-infected children and adolescents were included. MetS was defined according to the International Diabetes Federation and modified National Cholesterol Education Program Adult Treatment Panel III criteria. Measurements included anthropometry, waist circumference, blood pressure, fasting lipids, glucose and insulin, adiponectin, leptin, interleukin-6, vitamin D and C-reactive protein and clinical lipodystrophy assessment. RESULTS Among the total, 3.7% of patients met the International Diabetes Federation criteria for MetS and 7.4% met the National Cholesterol Education Program Adult Treatment Panel III criteria. C-reactive protein and leptin levels were significantly higher and adiponectin level significantly lower in patients with MetS, regardless of the criteria used. Insulin resistance was observed in 40.7% of patients; abnormal quantitative insulin sensitivity check index values were found in 88.9%. Eighteen patients (33.3%) had vitamin D deficiency. CONCLUSIONS The prevalence of MetS was similar to that observed in larger cohorts of HIV-infected patients in our setting. Adipocytokine dysregulation seems to be related to MetS in HIV-infected children. A high percentage of patients showed insulin resistance, which should be strictly monitored.

Abstract
OBJECTIVE The objective of this study is to review clinical outcomes of recommendations made by a multidisciplinary paediatric virtual clinic (PVC) for complex case management of paediatric HIV as a model of care within a tertiary network. DESIGN A retrospective review of the clinical outcomes of paediatric and adolescent (0-21 years) referrals to the PVC at St. Mary's Hospital, Imperial College Healthcare NHS Trust, London was performed between October 2009 and November 2013. RESULTS 234 referrals were made for 182 children from 37 centres, discussed in 42 meetings (median age 13 years, IQR 10-15 years). Reasons for referral included virological failure (44%), simplification of the current regimen (24%) and antiretroviral drug complications (24%). At latest follow-up, PVC advice had been instituted in 80% of referrals. Suppression following virological failure was achieved in 48% following first referral and 57% following subsequent discussions and was maintained in 95% of children referred for regimen simplification. Following advice, dyslipidaemia resolved in 42% and liver function normalised in 73% with biochemical hepatitis. Adherence support aided resolution of viraemia in nine children and 12% of referrals resulted in additional support, including psychology, social services and mental health input. CONCLUSIONS Combined multidisciplinary virtual input with adult expertise in resistance and newer agents, paediatric knowledge of pill swallowing, childhood formulations/weight banding and parental support, assists complex treatment decision making in paediatric HIV infection. The Virtual Clinic model could be applied to the management of other rare complex diseases of childhood within a clinical network.

Abstract
Background HIV infection occurs in 30% of children with severe acute malnutrition in sub-Saharan Africa. Effects of HIV on the pathophysiology and recovery from malnutrition are poorly understood. Methods We conducted a prospective cohort study of 75 severely malnourished Ugandan children. HIV status/CD4 counts were assessed at baseline; auxologic data and blood samples were obtained at admission and after 14 days of inpatient treatment. We utilized metabolomic profiling to characterize effects of HIV infection on metabolic status and subsequent responses to nutritional therapy. Findings At admission, patients (mean age 16.3 mo) had growth failure (mean W/H z-score −4.27 in non-edematous patients) that improved with formula feeding (mean increase 1.00). 24% (18/75) were HIV-infected. Nine children died within the first 14 days of hospitalization; mortality was higher for HIV-infected patients (33% v. 5%, OR = 8.83). HIV-infected and HIV-negative children presented with elevated NEFA, ketones, and even-numbered acylcarnitines and reductions in albumin and amino acids. Leptin, adiponectin, insulin, and IGF-1 levels were low while growth hormone, cortisol, and ghrelin levels were high. At baseline, HIV-infected patients had higher triglycerides, ketones, and even-chain acylcarnitines and lower leptin and adiponectin levels than HIV-negative patients. Leptin levels rose in all patients following nutritional intervention, but adiponectin levels remained depressed in HIV-infected children. Baseline hypoleptinemia and hypoadiponectinemia were associated with increased mortality. Conclusions Our findings suggest a critical interplay between HIV infection and adipose tissue storage and function in the adaptation to malnutrition. Hypoleptinemia and hypoadiponectinemia may contribute to high mortality rates among malnourished, HIV-infected children.

Abstract
This study reviewed the lipid profile of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) patients in relation to use of antiretroviral therapy (ART), and its different classes of drugs. A total of 190 articles published in peer-reviewed journals were retrieved from PubMed and LILACS databases; 88 of them met the selection criteria and were included in the review. Patients with HIV/AIDS without ART presented an increase of triglycerides and decreases of total cholesterol, low density lipoprotein (LDL-c), and high density lipoprotein (HDL-c) levels. Distinct ART regimens appear to promote different alterations in lipid metabolism. Protease inhibitors, particularly indinavir and lopinavir, were commonly associated with hypercholesterolemia, high LDL-c, low HDL-c, and hypertriglyceridemia. The protease inhibitor atazanavir is apparently associated with a more advantageous lipid profile. Some nucleoside reverse-transcriptase inhibitors (didanosine, stavudine, and zidovudine) induced lipoatrophy and hypertriglyceridemia, whereas abacavir increased the risk of cardiovascular diseases even in the absence of apparent lipid disorders, and tenofovir resulted in lower levels of cholesterol and triglycerides. Although non-nucleoside reverse-transcriptase inhibitors predisposed to hypertriglyceridemia and hypercholesterolemia, nevirapine was particularly associated with high HDL-c levels, a protective factor against cardiovascular diseases. Therefore, the infection itself, different classes of drugs, and some drugs from the same class of ART appear to exert distinct alterations in lipid metabolism.

Abstract
HIV-infected patients on highly active antiretroviral therapy (HAART) have increased prevalence of a number of chronic metabolic disorders of multifactorial but unclear etiology. These include disorders of lipid metabolism with or without lipodystrophy, insulin resistance, and an increased prevalence of impaired glucose tolerance, diabetes mellitus, and cardiometabolic syndrome. While much attention has been focused on the lipid and cardiovascular disorders, few investigations have attempted to characterize the prevalence, incidence, etiology, mechanisms, and management of glycemic disorders in HIV patients. In this review, we have focused specifically on a comprehensive assessment of dysglycemia in the context of HIV infection and HAART.

Abstract
O advento da AIDS trouxe novos desafios para a Dermatologia. A terapia antirretroviral mudou drasticamente a morbimortalidade associada à infecção pelo HIV/AIDS, mas contribuiu para o surgimento de outras novas situações que exigem abordagem adequada do dermatologista. A Síndrome Lipodistrófica Associada ao HIV/AIDS tem origem multifatorial, mas está fortemente associada ao uso dos antirretrovirais. Compreende alterações na distribuição da gordura corporal, acompanhada ou não de alterações metabólicas. A perda da gordura da face, chamada lipoatrofia facial, é dos sinais mais estigmatizantes da síndrome. Esta condição, muitas vezes reveladora da doença, trouxe de volta o estigma da AIDS. É necessário que os especialistas que atuam com pacientes com HIV/AIDS identifiquem estas alterações e busquem opções de tratamento, dentre as quais se destaca o implante com polimetilmetacrilato, que é disponibilizado para tratamento da lipoatrofia facial associada ao HIV/AIDS no Sistema Único de Saúde

Abstract
Metabolic complications of HIV pose challenges for health maintenance among young adults who acquired HIV in early childhood. Between July 2004 and July 2009, we evaluated 47 HIV-infected subjects who acquired HIV in early life. Participants completed glucose tolerance testing; insulin, lipid, urine albumin, and creatinine determinations; and dual-energy x-ray absorptiometry scans. Longitudinal data were available for 39 subjects; duration of follow-up was 26.4 ± 16.8 months. At baseline, participants were 17.1 ± 3.9 years old; and duration of antiretroviral therapy was 12.7 ± 3.4 years. CD4 count was 658 ± 374 cells per cubic millimeter, and 55% had undetectable viral load. Impaired glucose tolerance was present in 15%; 33% had insulin resistance (homeostasis model assessment of insulin resistance >4.0). Furthermore, 52% had triglycerides of at least 150 mg/dL, 36% had high-density lipoprotein cholesterol less than 40 mg/dL, 18% had low-density lipoprotein cholesterol of at least 130 mg/dL, and 25% had total cholesterol of at least 200 mg/dL. Microalbuminuria was present in 15% of participants and was inversely correlated with CD4% (P = .001). During follow-up, more than one third remained insulin resistant; lipid parameters tended to improve. There were significant increases in body mass index (P = .0002), percentage leg fat (P = .008), and percentage trunk fat (P = .002). Impaired glucose tolerance, insulin resistance, dyslipidemia, and microalbuminuria are common among young adults with HIV. Long-term exposure to therapy may translate into substantial persistent metabolic risk.

Abstract
To begin to unravel the complexity of HIV-associated changes in the brain, broader, multifaceted analyses of cerebrospinal fluid (CSF) are needed that examine a wide range of proteins reflecting different functions. To provide the first broad profiles of protein changes in the CSF of HIV-infected patients, we used antibody arrays to measure 120 cytokines, chemokines, growth factors, and other proteins. CSF from HIV-infected patients with a range of cognitive deficits was compared to CSF from uninfected, cognitively normal patients to begin to identify protein changes associated with HIV infection and neurological disease progression. Uninfected patients showed relatively consistent patterns of protein expression. Highly expressed proteins in CSF included monocyte chemotactic protein-1, tissue inhibitors of metalloproteases, granulocyte colony-stimulating factor, adiponectin, soluble tumor necrosis factor receptor-1, urokinase-type plasminogen activator receptor, and insulin-like growth factor binding protein-2. Inflammatory and anti-inflammatory cytokines were expressed at low levels. HIV-infected patients showed increases in inflammatory proteins (interferon-gamma, tumor necrosis factor-alpha), anti-inflammatory proteins (IL-13), and chemokines but these correlated poorly with neurological status. The strongest correlation with increasing severity of neurological disease was a decline in growth factors, particularly, brain-derived neurotrophic factor and NT-3. These studies illustrate that HIV infection is associated with parallel changes in both inflammatory and neuroprotective proteins in the CSF. The inverse relationship between growth factors and neurological disease severity suggests that a loss of growth factor neuroprotection may contribute to the development of neural damage and may provide useful markers of disease progression.

Abstract
OBJECTIVE The aim of the study was to evaluate the evolution of plasma adipokines and lipodystrophy in protease inhibitor-naıve vertically HIV-infected children on highly active antiretroviral therapy(HAART). PATIENTS AND METHODS We carried out a multicentre retrospective study of 27 children during 48 months on HAART. Every 3 months, CD4+ T-cells, CD8+ T-cells, viral load (VL), cholesterol, triglycerides, lipoproteins and adipokines were measured. Diagnoses of lipodystrophy were based on clinical examinations. RESULTS We found hypercholesterolaemia (4200 mg/dL) in 9.5, 30.4, 21.7, 14.3 and 13.3% of the subjects at months 0, 12, 24, 36 and 48, respectively, and hypertriglyceridaemia (4170 mg/dL) in 14.3, 8.3, 13,4.5 and 0% at the same time-points. During follow-up, and especially at the end of the study, we found an increase in plasma resistin levels and significant increases in total plasminogen activator inhibitor type 1, adiponectin, and leptin levels (Po0.05). We also observed slight increases in the leptin/adiponectin ratio, homeostatic model assessment, and C-peptide values during the first months of treatment followed by a moderate decrease or stabilization after 24 months on HAART.At the end of the study, 12 of the 27 children (44.4%) had lipodystrophy, 10 (37%) had lipoatrophy,and 11 (40.7%) had lipohypertrophy; and only three of the 27 children (11.1%) were diagnosed with lipoatrophy and lipohypertrophy with scores 2. CONCLUSIONS HIV-infected children showed an increase in serum adipokine levels, but this was not associated with the emergence of lipodystrophy during 48 months on HAART.

Abstract
Highly active antiretroviral therapy might lead to the development of dyslipidemia and lipodystrophy (LD) syndrome. We carried out a multicenter prospective study of 22 human immunodeficiency virus (HIV)-1-infected children treated during 48 months with lopinavir/ritonavir-based highly active antiretroviral therapy to evaluate the trend of serum lipids and adipokines. Increase in plasma leptin levels and leptin/adiponectin ratio was associated with LD. These adipokines may be surrogate markers of LD.

Abstract
Highly active antiretroviral therapy improves survival and growth in children with HIV infection. However, its use can be associated with adverse changes in body composition and metabolism. Bone mineral density can be adversely affected in HIV-positive children due to nutritional compromise or certain antiretrovirals. HIV-associated lipodystrophy, consisting of redistribution of adipose tissue, insulin resistance, and dyslipidemia, has also been described in children. Pediatric HIV patients may be at greater risk for these problems because of their longer potential lifetime exposure to these agents and because childhood is normally a period of rapid growth and tissue accretion. Healthcare providers for children with HIV infection must be aware of the potential complications associated with HIV antiretrovirals so that their antiviral efficacy can be balanced against their risk for side effects. In this review, we discuss the alterations in childhood growth and body composition that occur in HIV-infected children, and describe the impact of antiretroviral therapy on these outcomes. The problem of HIV-associated lipodystrophy syndrome in children is also discussed. Children with HIV should have their growth and body composition systematically monitored. Antiretroviral regimens should be tailored to optimize adherence and viral suppression while minimizing the potential for adverse side effects.

Abstract
Tremendous success in the prevention and treatment of pediatric HIV in high-resource countries has changed the face of the epidemic. A perinatally HIV-infected child now faces a chronic disease rather than a progressive, fatal one. However, these successes pose new challenges as perinatally HIV-infected youth survive into adulthood. These include maintaining adherence to long-term, likely life-long therapy; selecting successive antiretroviral drug regimens, given the limited availability of pediatric formulations and the lack of pharmacokinetic and safety data in children; and overcoming extensive drug resistance in multi-drug-experienced children. Pediatric HIV care now focuses on morbidity related to long-term HIV infection and its treatment. Survival into adulthood of perinatally HIV-infected youth in high-resource countries encourages expansion of pediatric treatment programs in low-resource countries, where most HIV-infected children live, and provides important lessons about how the epidemic changes with increasing access to antiretroviral therapy for children.

Abstract
OBJECTIVES The aim of the study was to describe growth and body composition changes in HIV-positive children after they had initiated or changed antiretroviral therapy (ART) and to correlate these with viral, immune and treatment parameters. METHODS Ninety-seven prepubertal HIV-positive children were observed over 48 weeks upon beginning or changing ART. Anthropometry and bioelectrical impedance analysis results were compared with results from the National Health and Nutrition Examination Survey 1999-2002 (NHANES) to generate z-scores and with results for HIV-exposed, uninfected children from the Women and Infants Transmission Study (WITS). Multivariate analysis was used to evaluate associations between growth and body composition and disease parameters. RESULTS All baseline lean and fat mass measures were below those of controls from NHANES. Weight, height and fat free mass (FFM) index (FFM/height(2)) z-scores increased over time (P = 0.004, 0.037 and 0.027, respectively) and the waist:height ratio z-score decreased (P = 0.045), but body mass index and per cent body fat z-scores did not change. Measures did not increase more than in uninfected WITS controls. In multivariate analysis, baseline height, mid-thigh circumference and FFM z-scores related to CD4 percentage (P = 0.029, P = 0.008 and 0.020, respectively) and change in FFM and FFM index z-scores to CD4 percentage increase (P = 0.010 and 0.011, respectively). Compared with WITS controls, baseline differences in height and mid-thigh muscle circumference were also associated with CD4 percentage. Case-control differences in change in both subscapular skinfold (SSF) thickness and the SSF:triceps skinfold ratio were inversely associated with viral suppression. No measures related to ART class(es) at baseline or over time. CONCLUSIONS In these HIV-positive children, beginning or changing ART was associated with improved growth and lean body mass (LBM), as indicated by FFM index. Height and LBM related to CD4 percentage at baseline and over time. Altered fat distribution and greater central adiposity were associated with detectable virus but not ART class(es) received.

Abstract
BACKGROUND HIV-associated lipodystrophy (LD) manifests with fat maldistribution, dyslipidemia, and insulin resistance in some HIV-infected children on antiretroviral therapy. AIM To assess whether lipid abnormalities in patients with HIV are stable over time. PATIENTS The perinatally HIV-infected cohort at a medium-sized urban US teaching hospital. METHODS This prospective, observational study consisted of five visits (at entry and 3, 6, 24, and 30 months after entry) during which fasting venous blood samples were drawn for HIV-1 RNA, CD4 lymphocytes, lipid profile, free fatty acids (FFA), glucose, insulin, and adiponectin. IGF-I/IGFBP-3 levels were measured at the first and fifth visits. RESULTS Of 36 study participants, seven were lipodystrophic, and 30 patients completed all five study visits. LDL-cholesterol, total cholesterol (TC), triglycerides (TG), and FFA levels were significantly higher in patients taking protease inhibitors (PIs). Patients with LD had higher TC and TG levels (both p < 0.05), and higher FFA (p = 0.0532). Adiponectin levels did not differ between PI/non-PI and LD/non-LD groups. HDL-cholesterol seemed to decrease, and FFA to increase over time. All IGF-I and all but one IGFBP-3 level were within normal range for age and Tanner stage. CONCLUSION Dyslipidemia remained relatively constant over our study period. Adiponectin was not useful as a marker of LD in our population.

Abstract
OBJECTIVES HIV-related lipodystrophy is a syndrome of adipose tissue redistribution, dyslipidaemia and insulin resistance. Combination antiretroviral therapy (CART) is a key risk factor. We hypothesized that fat redistribution in HIV-infected children is related to altered endocrine function of adipose tissue, namely leptin secretion. METHODS Serum leptin and fat redistribution were measured in 104 HIV-infected children in a prospective observational study from 2003 to 2004. Fat redistribution was defined by clinical observation. Body fatness was estimated using body mass index and four skinfold measurements. Serum leptin was determined using an enzyme-linked immunosorbent assay (Quantikine; R&D Systems, Abingdon, UK). Linear analogue models were used to adjust the leptin concentration for body fatness. RESULTS There was no significant difference in serum leptin among children treated with protease inhibitors (PIs), children on non-PI CART and children not treated with CART (P>0.05). When leptin concentrations were adjusted for body fatness, there was again no difference among PI-treated, non-PI-treated and untreated children. Categorization of CART exposure as never, current or past did not change these results. CONCLUSIONS There is no evidence that leptin plays any role in lipodystrophy other than reflecting body fatness.

Abstract
OBJECTIVE To compare growth, lipids and adipocytokines in HIV-positive children with and without lipoatrophy. PATIENTS Eleven HIV-positive children with facial lipoatrophy, and 22 age- and sex-matched HIV-positive controls without signs of fat abnormality. METHODS Clinical data including height, physical examination findings, medications, markers of viral control, cholesterol, and triglycerides were retrieved from the medical charts. Serum samples were analyzed for adiponectin, inflammatory markers, and high density lipoprotein cholesterol (HDL). RESULTS Lipoatrophy was associated with higher triglycerides (330 vs 133 mg/dl, p = 0.0003), lower HDL (33 vs 48 mg/dl, p = 0.02), and a greater frequency of hypercholesterolemia (total cholesterol > 200 mg/dl; 64% vs 23%, p < 0.03). Adiponectin was 53% lower in patients with lipodystrophy (6.9 microg/ml vs 14.8 microg/ml, p = 0.005), however there was no difference in the inflammatory markers soluble TNFa receptor 2 or interleukin 6. Strikingly, despite similar BMI z-scores and virological control, lipoatrophic patients were shorter by 1 standard deviation score (p = 0.03). CONCLUSIONS The presence of facial lipoatrophy in a child with HIV infection is a marker for significant metabolic derangements including dyslipidemia and hypoadiponectinemia, and suggests the need for careful growth evaluation.
