Abstract
OBJECTIVE HIV/AIDS and malnutrition combine to undermine the immunity of individuals and are inextricably interrelated. Although the effect of highly active antiretroviral therapy (HAART) on growth in HIV-infected children is well known, the influence of prior nutritional and immunologic status on the response to HAART is not well documented. The aim of the present study was to determine the effects of HAART on nutritional and immunological status in HIV-infected children in the low-income country of Ethiopia. METHODS A multicenter, retrospective cohort study was conducted on HIV-infected children receiving antiretroviral therapy at the pediatric units of public hospitals in Addis Ababa (Black Lion, Zewditu, Yekatit 12 and ALERT hospitals), Ethiopia. Nutritional status was defined as stunting (height-for-age Z score [HAZ] <-2), wasting (weight-for-height Z score [WHZ] <-2), and underweight (weight-for-age Z score [WAZ] <-2). Multivariable logistic regression was used to analyze factors associated with treatment success and to establish whether growth (baseline nutritional status) in children predicts immunologic outcomes. In all, 556 HIV-infected children receiving HAART from January 2008 to December 2009 were included in this study. RESULTS Over the 24-mo follow-up period, the study showed that the immunologic recovery of stunted and underweight children, regardless of their baseline nutritional status, responded equally to treatment. However, wasted children showed less immunologic recovery at the different follow-up visits. Predictors of positive shift in WHZ after 24 mo of follow-up were advanced disease stage (World Health Organization clinical stages 3 and 4) with odds ratio (OR), 0.25 (95% confidence interval [CI], 0.34-0.99; P = 0.045) and baseline severe underweight OR, 0.19 (95% CI, 0.09-0.56; P = 0.003). The independent predictors of positive shift of growth shift in WAZ over 24 mo were lower baseline age (<36 mo) with OR, 0.21 (95% CI, 0.04-0.90; P = 0.036) and baseline moderate underweight itself with OR, 0.11 (95% CI, 0.05-0.25; P = 0.0001) were predictors of positive shift (shift to normal). CONCLUSION Despite the apparent growth response in HIV-infected children after initiation of HAART, moderate and severe underweight are both independent predictors of a positive shift. The latter suggests that children on HAART require nutritional supplementation, especially during the early initiation of HAART.

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”. We hope that this review will support the work of pediatricians, clinicians and infectious diseases specialists that are receiving these subjects to continue treatment.

Abstract
BACKGROUND Growth failure often precedes secondary infections in HIV-infected infants and children, suggesting that inadequate protein deposition may be an early manifestation of infection by the virus. However, the protein metabolic response elicited by the virus in young children is unknown. OBJECTIVE We compared children with HIV infection and age-matched children without HIV infection with regard to whole-body and splanchnic protein kinetics and synthesis of acute phase proteins (APPs). DESIGN Whole-body and splanchnic leucine kinetics and fractional and absolute synthesis rates of 2 positive and 4 negative APPs were measured in 6 asymptomatic, HIV-infected children (4 males and 2 females) aged 6-17 mo and 4 uninfected children (3 females and 1 male) aged 7-9 mo who were in the fed state. RESULTS Compared with the control children, the HIV-infected children had significantly lower dietary energy and protein intakes and leucine balance and significantly faster leucine flux and fractional splanchnic leucine extraction; there was no significant difference between the groups in leucine oxidation rates. The HIV-infected children also had significantly higher plasma concentrations and absolute synthesis rates of the positive APPs and a significantly higher fractional synthesis rate of fibrinogen. The concentrations of 2 of the 4 negative APPs, albumin and HDL apolipoprotein A-I, were significantly lower in the HIV-infected children but were not associated with slower synthesis rates. CONCLUSIONS Children with HIV infection but without secondary infection have reduced protein balance because of an inability to down-regulate protein catabolism. Furthermore, the acute phase protein response elicited by HIV infection is characterized by higher concentrations and synthesis rates of positive APPs without lower concentrations of some negative APPs.

Abstract
Nutritional management is integral to the care of all patients infected with human immunodeficiency virus (HIV). HIV infection results in complicated nutritional issues for patients, and there is growing evidence that nutritional interventions influence health outcomes in HIV-infected patients. We define levels of nutritional care, and we discuss when patients should be referred to providers (i.e., registered dietitians) with nutritional and HIV expertise.

Abstract
Many children who are HIV infected grow poorly. An epidemiological framework guided a retrospective chart review assessing growth in three groups of children (n = 192): (a) children who were HIV infected secondary to maternal transmission (n = 77), (b) children who had been HIV-positive at birth but became seronegative and continue to be observed (seroreverters) (n = 84), and (c) HIV-infected children who had died (n = 31). Growth failure in the HIV-infected children was significantly greater than that expected in the general population. The seroreverters also demonstrated significantly more growth failure than that expected in the general population. Of the children who had linear growth failure, only 3 of 12 HIV-infected children and 2 of 11 seroreverters also had inadequate weight gain. However, 13 of 15 children with growth failure who subsequently died had poor weight gain. HIV classification was not significantly related to growth. These findings extend our understanding to a large, urban population of children in the United States including those who are older than children in other studies and who developed HIV through perinatal transmission. Nursing clinical practice and research implications are offered.

Abstract
To better characterize the somatotropic axis in HIV-infected children the circadian rhythm of growth hormone (GH), and basal and stimulated (by an insulin-like growth factor I [IGF-I] generation test) plasma levels of IGF-I and insulin-like growth factor-binding protein 3 (IGFBP-3), were evaluated in 16 children (9 boys and 7 girls; age range, 7-11 years) with HIV infection. All patients were free from active opportunistic infection or liver disease at the time of the study. Sixteen age- and sex-matched healthy children (10 boys and 6 girls; age range, 7-11 years) served as control subjects. GH rhythmometric data were analyzed by single and population mean cosinor analysis. As regards the IGF-I generation test, biosynthetic human GH (hGH, 0.1 IU/kg, 0.033 mg/kg) was administered subcutaneously for 4 days and blood samples were taken from fasting subjects at baseline and on the morning after the last GH injection for measurement of IGF-I and IGFBP-3. Plasma GH levels fell within normal limits in the HIV-seropositive patients and were similar to those of healthy children (1.31 +/- 1.18 vs. 1.57 +/- 1.16 microg/liter, respectively; mean +/- SD). The population mean cosinor analysis shows that the GH circadian rhythm reached statistical significance both in the HIV-seropositive children and in the control group. Despite this, the IGF-I and IGFBP-3 levels were significantly lower in HIV-infected children than in the control group (75.6 +/- 57.2 vs. 233.3 +/- 52.5 ng/ml, p < 0.001 and 2.09 +/- 0.17 vs. 3.89 +/- 0.24 mg/liter, p < 0.01, respectively; mean +/- SD); moreover, the response of IGF-I and IGFBP-3 to the IGF-I generation test was significantly lower in HIV-infected children than in the control group (86.3 +/- 55.8 vs. 257.5 +/- 53.4 ng/ml, p < 0.001 and 3.14 +/- 0.43 mg/liter, p < 0.01, respectively; mean +/- SD). It appears that circadian GH secretion is normal in children with HIV infection, but the response to exogenous GH with regard to IGF-I and IGFBP-3 production is impaired, indicating a degree of GH insensitivity in such children.

Abstract
INTRODUCTION Growth failure is a common feature of children with human immunodeficiency virus type 1 (HIV-1) infection. Children who are treated with mono or dual nucleoside analogue reverse transcriptase inhibitor (NRTI) therapy show a temporary increase in weight gain and linear growth rate. In adults, protease-inhibitor-containing antiretroviral therapy is associated with a sustained weight gain and increased body mass index (BMI). Experience with protease inhibitors and growth in children is still limited. The data mainly deal with short-term effects on growth. OBJECTIVE To evaluate the effect of highly active antiretroviral therapy (HAART) on growth in children with HIV-1 infection. DESIGN AND METHODS We analyzed selected growth parameters, clinical data, and laboratory results as part of a prospective, open, uncontrolled, multicenter study to evaluate the clinical, immunologic, and virologic response to HAART consisting of indinavir, zidovudine, and lamivudine in children with HIV-1 infection. Height and weight were measured at 0, 12, 24, 36, 48, 60, 72, 84, and 96 weeks after initiation of HAART. Information about the children's growth before enrollment in the study was retrieved from the hospital medical records and/or the school doctor or health center. BMI was calculated. z Scores were used to express the standard deviation (SD) in SD units from the Dutch reference curves for age and gender. Viral loads and CD4+ T-cell counts were examined prospectively and related to these growth parameters. z Scores were also calculated for CD4+ T-cell counts to correct for age-related differences. A z score of 0 represents the P50, which is exactly the age/sex-appropriate median. A height z score of -1 indicates that a child's height is 1 SD below the age- and gender-specific median height for the normal population. Virologic responders were defined as those who either reached an undetectable viral load (<500 copies/mL) or had a >1.5 log reduction in viral load compared with baseline at week 12 after the initiation of HAART, which was maintained during the follow-up period. RESULTS. PATIENTS Twenty-four patients were included (age: 0.4-16.3 years at baseline), with a median HIV-1 RNA load of 105 925 copies/mL (5.03 log), a median CD4+ T-cell count of 0.586 x 10(9)/L (median z score: -2.28 SD), a median height z score of -1.22, a median weight z score of -0.74, and a median baseline BMI z score of -0.32. Eleven patients were naive to antiretroviral therapy, and 13 patients had received previous treatment with NRTI monotherapy. Twenty children used indinavir and 4 children used nelfinavir as part of HAART. VIROLOGIC AND IMMUNOLOGIC RESPONSES TO HAART: Seventeen children were virologic responders, and 7 children were virologic nonresponders. In patients naive to NRTIs, median baseline viral loads were significantly higher than in pretreated patients. However, at weeks 48 and 96, there was no significant difference between the viral loads of both groups. At baseline, there was no significant difference in CD4+a T-cell z scores between virologic responders and nonresponders or between naive and pretreated patients. During 96 weeks of HAART, the increase of CD4+ T-cell z score was significantly higher in responders than in nonresponders. The increase in CD4+ T-cell z score was not significantly different for naive and pretreated patients. HEIGHT, WEIGHT, AND BMI z SCORE CHANGES: We found that there was a trend toward a significantly increased z score change during 96 weeks of HAART compared with the z score change before HAART initiation for height and weight, but not for BMI. GROWTH AND VIROLOGIC RESPONSE TO HAART: When the data were analyzed separately for virologic responders and nonresponders, virologic responders showed significant increases in height and weight. The height and weight of virologic nonresponders did not change significantly. The BMI did not change significantly in responders or in nonresponders. GROWTH AND IMMUNOLOGIC RESPONSE TO HAART: The increase of weight and BMI z scores from baseline correlated positively with the CD4+ T-cell z score increase from baseline. It did not correlate with absolute CD4+ T-cell count increase. Height z score increase did not correlate with CD4+ T-cell z score or with absolute CD4+ T-cell counts. GROWTH AND PREVIOUS NRTI TREATMENT: The height z score decrease from week -48 to baseline was significantly larger in naive than in pretreated patients. The weight and BMI z score change from week -48 to baseline was not significantly different for pretreated and naive patients. From baseline to week 96, the height and weight z score change increased significantly in naive patients but not in pretreated patients compared with the change from week -48 to baseline. The BMI z score did not change significantly over 96 weeks of HAART for naive or pretreated patients. GROWTH AND CLINICAL STAGE OF INFECTION: The clinical stage of infection according to the Centers for Disease Control and Prevention classification correlated negatively with the BMI z score and the weight z score at baseline but not with the height z score. Thus, children with the most severe clinical disease had the lowest BMI and weight z scores at baseline. The BMI z score increased more in children with more advanced clinical infection at baseline, who had lower BMI at baseline. The clinical stage of infection did not correlate with the change in weight z score from baseline to week 96. CONCLUSIONS HAART has a positive influence effect on the growth of HIV-1-infected children. This effect is sustained for at least 96 weeks. Height and weight are favorably influenced in children in whom HAART leads to a reduction of the viral load of at least 1.5 log or to <500 copies/mL and to an increase in the CD4+ T-cell z score. In contrast to the increase of the BMI in adults on HAART, BMI did not increase in all children effectively treated with HAART. BMI increased more in children with an advanced stage of infection and a poor nutritional status at baseline. Data from pretreated and naive patients were difficult to interpret, because the baseline characteristics of these 2 groups differed too much.

Abstract
This study describes growth in a cohort of black South African children born to HIV-1-infected women in Durban. Children born to HIV-1-seropositive women were followed up from birth to early childhood. At birth and at each visit, growth parameters were measured. Mean Z-scores were calculated for weight-for-length, weight-for-age and length-for-age and, if they were low, the children were regarded as wasted, malnourished or stunted, respectively. At the end of the study, there were 48 infected and 93 uninfected children. There were no significant differences between the two groups at birth. Thereafter, the infected group was found to have early and sustained low mean Z-scores for length-for-age and weight-for-age but not for weight-for-length. The means reached significance at ages 3, 6 and 12 months for length and at 3, 6 and 9 months for weight. Infected children who died early had more severe stunting, wasting and malnutrition than infected children who survived. Infected children born to HIV-positive women have early and sustained stunting and are malnourished but not wasted. Children with rapidly progressive disease have both stunting and wasting and are more severely affected. Early nutritional intervention might help prevent early progression or death in HIV-infected children, particularly in developing countries without access to anti-retroviral therapy in state hospitals.

Abstract
BACKGROUND Early diagnostic efforts and advances in multidrug therapy have considerably prolonged the survival time of children infected perinatally with HIV. Despite these advances, few studies have addressed calcium status and bone growth in HIV-infected children. OBJECTIVE Our objective was to examine the effect of HIV infection on calcium status and bone growth in children. DESIGN We measured calcitropic hormones, urinary calcium excretion, bone mineral content, and body composition in 19 young girls aged 9.2 +/- 2.6 y (range: 5.9-15.2 y) who were infected perinatally with HIV. RESULTS Serum concentrations of 1,25-dihydroxyvitamin D [1,25(OH)(2)D] and parathyroid hormone concentrations were elevated above normal ranges in 25% and 12% of these girls, respectively. Urinary calcium excretion normalized for creatinine excretion was also elevated (Ca/Cr >0.18) in 17% of these children despite suboptimal calcium intakes (679 +/- 437 mg/d). Total-body bone mineral content, measured with the use of dual-energy X-ray absorptiometry, averaged 845.1 +/- 279.0 g and was on average 2.7 z scores below age- and race-matched values reported in non-HIV-infected healthy girls. Significant positive correlations were found between an indirect marker of bone resorption in urine (N:-telopeptide) and 1,25(OH)2D (P < 0.02, r2 = 0.586, n = 9), and between serum N-telopeptide and total alkaline phosphatase (P < 0.001, r2 = 0.541, n = 17), suggesting that calcium insufficiency may be increasing bone resorption in this group. CONCLUSIONS Young girls with HIV infection had low bone mass and evidence of calcium insufficiency. Nutritional counseling of children with HIV infection should emphasize adequate calcium intakes because of the importance of this age period in bone mineral acquisition.

Abstract
OBJECTIVE The investigation examined the associations of plasma human immunodeficiency virus (HIV) RNA and CD4(+) T lymphocytes with height, weight, skeletal maturation, testosterone levels, and height velocity for hemophilic children and adolescents with HIV infection in the Hemophilia Growth and Development Study. STUDY DESIGN Two hundred seven participants were evaluated over 7 years. RESULTS A threefold increment in baseline plasma HIV RNA was associated with a 0.98-cm decrease in height and a 1.67-kg decrease in weight; 100-cells/microL decrements in baseline CD4(+) were associated with a 2.51-cm decrease in height and a 3.83-kg decrease in weight. Participants with high plasma HIV RNA (>3125 copies/mL) experienced significant delay in achieving maximum height velocity and lower maximum velocity compared with those with low viral load. The high CD4(+) (>243)/low plasma HIV RNA group had earlier age at maximum height velocity compared with the other 3 groups and higher maximum height velocity compared with the low CD4(+)/high plasma HIV RNA and low CD4(+)/low plasma HIV RNA groups. Decrements in CD4(+) were associated with decreases in bone age and testosterone level. CONCLUSIONS CD4(+) and HIV RNA were important in predicting growth outcomes.

Abstract
Poor growth is reported in as many as 50% of HIV-infected children. HIV infection adversely affects pregnancy outcome; infants born to HIV-infected women have significantly lower mean birth weight and length, regardless of the infants' HIV status, compared with infants born to uninfected women. Pediatric HIV further reduces birth weight. Progressive stunting, that is, proportionately decreased linear and ponderal growth, appears to be the most common abnormality in perinatally infected children and is accompanied by preferential decreases of fat-free or lean body mass. Although data are inconsistent, deficiencies of several micronutrients with the potential to affect growth adversely have been identified, including that of vitamin A. Neuroendocrine abnormalities also occur, including abnormal thyroid, growth hormone/ insulinlike growth factor-1, and adrenal function; however, no consistent endocrine abnormality is observed in HIV-associated growth failure. Infections of the gastrointestinal tract and malabsorption of carbohydrates, fat, and protein are common, but no relationship between these disorders and poor growth has been demonstrated. Despite normal rates of resting and total energy expenditures, the mean daily dietary intake of children with growth failure (GF) appears to be inadequate. Inadequate dietary intake is not the sole cause of GF; dietary supplementation improves weight but does not correct deficits in lean tissue or height. Levels of HIV RNA are greater in children with poor growth compared with infected children with normal rates of growth. How HIV replication impedes growth has not been established but suppression of HIV appears to have a favorable effect on ponderal and linear growth. Further investigations are necessary to evaluate the potential role of anabolic agents for the management of HIV-associated growth failure.

Abstract
OBJECTIVES To evaluate clinical conditions associated with mortality in HIV-infected children with CD4+ counts <100 cells/microl. METHODS The Pediatric Spectrum of HIV Disease Project is a longitudinal medical record review study with eight study sites in the United States, which have been enrolling children since 1989. Survival time from baseline very low CD4 count (<100 cells/microl) to death was estimated using the Kaplan-Meier method. Cox proportional hazards models were used to evaluate the effect of clinical variables on mortality. RESULTS Of 522 children (>/=1 year of age) with serial CD4+ T-lymphocyte measurements, the median age at the first very low CD4 count was 4.8 years. The estimated median survival following the first very low CD4 count was 36 months. The following factors present at the first very low CD4 count were independently associated with a higher risk of death: younger age, weight-for-age >2 standard deviations below the mean, and previously diagnosed AIDS. The subsequent development of cytomegalovirus (CMV)-associated disease, Mycobacterium avium intracellulare (MAI) infection, wasting syndrome, or esophageal candidiasis was also independently associated with a higher risk of death. CONCLUSION Survival in HIV-infected children with very low CD4 counts before introduction of highly active antiretroviral therapy was highly variable. Poor nutritional status and the development of CMV disease or MAI infection were associated with the shortest survival times.

Abstract
Poor growth is reported in as many as 50% of HIV-infected children. HIV infection adversely affects pregnancy outcome; infants born to HIV-infected women have significantly lower mean birth weight and length, regardless of the infants' HIV status, compared with infants born to uninfected women. Pediatric HIV further reduces birth weight. Progressive stunting, that is, proportionately decreased linear and ponderal growth, appears to be the most common abnormality in perinatally infected children and is accompanied by preferential decreases of fat-free or lean body mass. Although data are inconsistent, deficiencies of several micronutrients with the potential to affect growth adversely have been identified, including that of vitamin A. Neuroendocrine abnormalities also occur, including abnormal thyroid, growth hormone/ insulinlike growth factor-1, and adrenal function; however, no consistent endocrine abnormality is observed in HIV-associated growth failure. Infections of the gastrointestinal tract and malabsorption of carbohydrates, fat, and protein are common, but no relationship between these disorders and poor growth has been demonstrated. Despite normal rates of resting and total energy expenditures, the mean daily dietary intake of children with growth failure (GF) appears to be inadequate. Inadequate dietary intake is not the sole cause of GF; dietary supplementation improves weight but does not correct deficits in lean tissue or height. Levels of HIV RNA are greater in children with poor growth compared with infected children with normal rates of growth. How HIV replication impedes growth has not been established but suppression of HIV appears to have a favorable effect on ponderal and linear growth. Further investigations are necessary to evaluate the potential role of anabolic agents for the management of HIV-associated growth failure.

Abstract
This report summarizes data on the availability of essential fatty acids (EFAs) and their long-chain polyunsaturated fatty acid (LCPUFA) metabolites in protein-energy malnutrition (PEM), in human immunodeficiency virus-1 (HIV-1) infection for which less information is available, and the combination of both PEM and HIV-1. The contribution of different EFAs and LCPUFAs to the fatty-acid composition of plasma and erythrocyte membrane lipids was found to be reduced in children with PEM in comparison with well-nourished children. In addition to limited dietary EFA supply, reduced bioconversion of EFAs to their respective LCPUFA metabolites and/or peroxidative degradation of LCPUFAs may contribute to the reduction of LCPUFA status in malnourished children. Restoration of normal energy, protein, and EFA intakes does not appear to readily correct abnormalities of plasma and erythrocyte membrane LCPUFA values. Enhanced dietary supply of LCPUFAs and/or improved supply of antioxidant vitamins may represent novel therapeutic modalities in severe PEM. With and without PEM, HIV infection was related to altered availability of various EFAs and LCPUFAs in HIV-seropositive children. The plasma total lipid fatty-acid profiles seen in well-nourished children with HIV infection were compatible with an HIV infection-related enhancement of the metabolic activity of the conversion of EFAs to their respective LCPUFA metabolites. However, the plasma phospholipid EFA and LCPUFA profiles seen in severely malnourished children with HIV infection more closely resembled those seen in children with PEM but without HIV infection than in those in children with HIV infection but no PEM. Metabolic studies using stable isotope-labeled fatty acids may contribute to better understanding of the HIV-related changes in EFA metabolism and clearly are needed before therapeutic conclusions can be drawn.

Abstract
OBJECTIVE To determine the safety and efficacy of anabolic therapy to prevent or reverse wasting and malnutrition in human immunodeficiency virus (HIV)-infected pediatric patients. The anabolic steroid, oxandrolone, was evaluated because of its safe and effective use in other pediatric conditions. METHODS Nine HIV-positive children who were malnourished or at risk for malnutrition (4 females, 5 males; 4-14 years of age) took oxandrolone for 3 months (.1 mg/kg/day orally). Quantitative HIV ribonucleic acid polymerase chain reaction and CD4(+) T-cell levels, complete blood cell count (CBC) and chemistry profile, endocrinologic studies, resting energy expenditure, respiratory quotient, nutritional measures, body composition assessment with quantitative computed tomography, and skinfold body composition measurements were determined before treatment, during treatment (3 months), and for 3 months after treatment. Statistical analyses were completed using the Friedman two-way analysis of variance and Spearman correlation tests. RESULTS No adverse clinical or laboratory events or changes in Tanner staging or virilization occurred. Quantitative HIV ribonucleic acid polymerase chain reaction and CD4(+) T-cell levels did not change significantly. Insulin-like growth factor 1 increased, suggesting an anabolic effect of treatment. The rate of weight gain increased during treatment and was maintained after treatment. Linear growth continued and was maintained throughout treatment, whereas bone age did not increase significantly. Anthropometric assessments indicated an increase in muscle mass and a decrease in fat while patients were on treatment, and a mild decrease of muscle and increased fat posttreatment. Likewise, computed tomography scan results demonstrated similar changes in muscle mass. Resting energy expenditure and respiratory quotient remained stable throughout treatment and follow-up. No significant changes were seen in the quality of life questionnaire. CONCLUSIONS Treatment with oxandrolone for 3 months in HIV-infected children was well-tolerated, safe, and associated with markers of anabolism. The latter effect was maintained partially for 3 months after discontinuation of a 3-month course of therapy. Additional studies are needed to assess the potential benefits and risks of a longer course of therapy or a higher dose of oxandrolone in HIV-infected children.

Abstract
As part of the Hemophilia Growth and Development Study (HGDS), we investigated the relationship between HIV-associated immune dysfunction and delayed pubertal development in a cohort of 333 boys and adolescents with moderate or severe hemophilia who were between the ages of 6 and 19 years at study entry in 1989. Sixty-two percent of the cohort was infected with HIV in the late 1970s and early 1980s through exposure to contaminated clotting factor concentrates. The cohort was observed during follow-up at 6-month intervals; measurements taken at each follow-up visit included Tanner stage and CD4+ cell count. This analysis of data from the first 4 years of follow-up revealed statistically significant delays in pubertal development associated with increasing levels of immune dysfunction. Our results emphasize the importance of following pubertal development in HIV-infected adolescent boys since delays in maturation may reflect underlying disease progression.

Abstract
The purpose of this study was to determine whether alterations in body composition, resting energy expenditure (REE), and dietary energy intake are associated with growth retardation in HIV-positive children. Body composition (deuterium oxide dilution, skinfold measurements), REE (indirect calorimetry), and energy intake (24-hour weighed food intake) were evaluated in three groups: HIV-positive with growth retardation (HIV+Gr), HIV-positive with normal growth (HIV+); and HIV-uninfected with normal growth (HIV-). Children were between 2 and 11 years of age, afebrile, and free from acute infection. Forty-two children (13 HIV+Gr, 19 HIV+, 10 HIV-) were studied. Lean body mass was significantly reduced in HIV+Gr compared with HIV- (p < .05), and fat mass was significantly reduced in HIV+Gr and HIV+ compared with HIV- (p < .05). The percentages of lean and fat mass were not significantly different between groups, suggesting that differences in lean and fat mass were proportional to differences in body size. Consistent with reduced lean body mass, mean REE was significantly lower in HIV+Gr compared with HIV- (p < .05). Differences in mean REE/kg of body weight or lean body mass between groups were not statistically significant. A significant negative correlation was found between REE (kcal/kg/day) and weight-for-age (p = .04), and a trend with height-for-age Z-score (p = .07). Mean energy intake was not significantly different between groups. This study suggests that lean and fat mass are proportionately reduced in HIV-positive children with growth retardation. Further studies are necessary to delineate the relationship between energy balance and growth in children with HIV infection.

Abstract
OBJECTIVE To evaluate the circadian secretion of hormones involved in the regulation of growth in childhood, namely growth hormone, insulin-like growth factor (IGF)-I, cortisol, adrenocorticotropin hormone (ACTH), and thyroid-stimulating hormone (TSH) in HIV-infected children. DESIGN The circadian secretory pattern of growth hormone, IGF-I, cortisol, ACTH and TSH was evaluated in 14 HIV-infected children; 13 healthy age- and sex-matched children were chosen as controls. METHODS Sampling was performed every 4 h from 0400 h to 2000 h and every 2 h from 2000 h to 0400 h. Rhythmometric data were analysed by single and population mean cosinor methods and by analysis of variance. RESULTS A statistically significant circadian rhythm for growth hormone, IGF-I and cortisol was detectable in HIV-seropositive children, but the mean basal IGF-I levels were below the normal range for age in 12 patients. A statistically significant circadian rhythm was not detectable for ACTH or TSH. CONCLUSION These results show that there is a loss of the physiological regulation of growth hormone-IGF-I axis and a modification of 24 h TSH profile in our HIV-infected children. These abnormalities might be involved in the altered growth mechanism leading to the failure to thrive that is a peculiar feature of HIV-infected children.

Abstract
To determine factors associated with survival in a cohort of HIV-infected children and adolescents with hemophilia, an analysis of the 5-year mortality data for 207 HIV-infected young men was performed to examine the effect of selected clinical covariates on survival. The subjects were enrolled into the Hemophilia Growth and Development Study cohort from 1989 to 1990. Estimated mean time since infection at baseline was 6.7 years and mean estimated age at infection was 6.5 years. The baseline characteristics examined for their association with the hazard of death over the 5-year follow-up period were the following: absolute CD4+ cell count, hemoglobin status, skin test anergy, results of brain magnetic resonance imaging, non-hemophilia-related muscle atrophy (NHRMA), height for age, and impaired neuropsychological functioning as measured by the Vineland Adaptive Behavior and the Pediatric Behavior Scales. In all, 66 deaths occurred over the 5-year follow-up, 62 of whom met the 1987 (n = 56) or 1993 (n = 6) U.S. Centers for Disease Control and Prevention (CDC) definition of AIDS. Although each of the characteristics listed previously significantly increased the hazard of death by Cox proportional hazard regression models, only NHRMA remained a significant predictor of AIDS-related death when added to models that included each of the other cited baseline covariates.

Abstract
OBJECTIVE To describe the natural history of somatic growth in HIV infection by constructing age-specific growth velocity norms and to assess specific prognostic information available using these norms. DESIGN Observations on 1338 HIV-infected children aged 3 months to 15 years who participated in one of four US clinical trials of pediatric anti-HIV therapies were pooled; baseline growth velocity data were obtained using the first 6 months of observation for each child. METHODS Distributions of physical growth velocities in HIV-infected children in the Pediatric AIDS Clinical Trials Group were computed. Statistical smoothing of growth histories was employed to derive velocity estimates, and quantile regression analysis of growth velocities was performed to allow comparisons of growth rates in age- and gender-heterogeneous cohorts in the context of HIV infection. The quantile regressions provide corrected z-scores for growth velocity that appropriately compare HIV-infected children with one another for the purpose of distinguishing more from less favorable prognoses. RESULTS Consistent deficits in growth velocity amongst HIV-infected children were revealed when compared with the Fels Institute velocity standards. Approximately 33% of height (and 20% of weight) age- and sex-corrected velocity measurements obtained in the first 6 months of clinical trial participation lay beneath the corresponding third percentiles of the Fels reference distributions, which are commonly regarded as critical indicators of growth failure. Proportional hazards regression tests indicated that both weight and height velocity contributed significant information on the risk of death among children with AIDS after adjusting for antiretroviral therapy received, CD4 cell counts, and age at trial enrollment. Comparing subjects who differ in initial weight velocity by one age- and sex-corrected SD, the relative hazard of death was 0.63 (95% confidence interval, 0.55-0.72; P < or = 0.0001) in favor of the child with greater weight velocity, controlling for antiretroviral therapy received, age and CD4 cell count at baseline. The analogous hazard ratio for height velocity was 0.68 (95% confidence interval, 0.57-0.79; P < or = 0.0001). CONCLUSIONS Suitably normalized growth velocities are informative and inexpensive criteria for pediatric AIDS prognosis; the growth velocity distributions presented will be useful for comparing growth effects of new therapeutic strategies to those of single and combination antiretrovirals employed for maintenance of pediatric HIV infection in the mid-1990s.

Abstract
BACKGROUND Nutritional dwarfing, a form of suboptimal nutrition, has been identified as a frequent cause of short stature and delayed sexual development in children. Retarded growth is an adaptive response to suboptimal nutrition. OBJECTIVE To assess whether recombinant human growth hormone (rhGH) may promote growth during various levels of suboptimal nutrition. METHODS Using a previously developed rat model of suboptimal nutrition, six groups of rats (six rats/group) were fed a balanced 1:1 carbohydrate:fat ratio diet for 4 weeks. Three of the groups were administered daily injections of rhGH (0.1 mg/100 g BW) subcutaneously in the back while the other three groups were kept as controls and were given similar dosages of normal saline solution (NSS). Restricted rats within each treatment group were pair fed 80 and 60% of the ad-libitum rats intake. Daily intake of the 80 and 60% fed groups were determined based on the intake of the ad-libitum fed groups. Serum IGF-I and insulin were determined after 4 weeks of dietary treatment by radioimmunoassay while IGFBP-3 was determined by an immunoradiometric assay. Body composition was assessed in all rats by carcass analysis. RESULTS After 4 weeks, total weight gain and tail growth were higher (p < 0.05) in the rhGH treated group at 80 and 60% of-libitum energy intake. Serum levels of IGF-I and IGFBP-3 were higher (p < 0.05) in rhGH treated rats fed at 60% of ad-libitum. In comparison to the NSS groups, administration of rhGH in rats fed ad-libitum increased total body water. Energy restriction caused decreased fat percentage (p < 0.05) in both rhGH and NSS groups without differences among treated groups. CONCLUSION These results suggest that the anabolic effects of rhGH may overcome mild to moderate energy restriction.

Abstract
OBJECTIVE To determine whether reduced serum or plasma protein and micronutrient levels are common in children infected with the human immunodeficiency virus (HIV) and whether these levels are different in children with growth retardation compared to those with normal growth. SUBJECTS Children were separated into three groups: (a) HIV-infected with growth retardation (HIV + Gr); (b) HIV-infected with normal growth (HIV+); (c) HIV-uninfected with normal growth (HIV-). All children were afebrile and free of acute infection at the time of study. During a 24-hour stay in the Pediatric Clinical Research Unit, blood was drawn for analysis of total protein, albumin, zinc, selenium, and vitamin A levels; growth measurements were obtained; and dietary intake was assessed by 24-hour weighed food intake and 24-hour dietary recall. STATISTICAL ANALYSIS Mean differences between groups were assessed by analysis of variance, and differences in the frequency of nutrient deficiency were determined by chi 2 analysis. RESULTS Thirty-eight children between 2 and 11 years of age were studied: 10 HIV + Gr, 18 HIV+, and 10 HIV-. No statistically significantly differences were noted in mean levels of albumin, prealbumin, zinc, and selenium. Mean serum level of vitamin A was significantly higher in the HIV + Gr group than in the other two groups. There were no significant differences between groups in the frequency of deficiency for any nutrient studied. Mean energy and nutrient intake was similar among groups. APPLICATIONS/CONCLUSIONS Abnormal serum or plasma protein or micronutrient levels were uncommon in this cohort of HIV-infected children, even in children with growth retardation. Routine monitoring of the level of proteins and micronutrients studied is unnecessary in the absence of specific clinical indicators of deficiency.

Abstract
UNLABELLED Growth and pubertal development in hemophilic males, age 6-19 years at baseline, were evaluated over a 3.5-year period in 207 HIV-positive and 126 HIV-negative subjects as part of the Hemophilia Growth and Development Study. METHODS Thyroid function, insulin-like growth factor I (IGF-1) levels, bone age, cranial magnetic resonance image normality, CD4+ counts, and serum testosterone levels of study participants were measured at baseline. An extensive endocrine evaluation was performed in subjects who demonstrated declines in height for age (measurement <5th percentile with two pervious heights >10th percentile), who had not achieved Tanner stage 4 level of pubertal development by age 15 years or who had abnormal growth velocity, which included assessment of peak stimulated growth hormone response after clonidine stimulation, 12-hour growth hormone profiles, and serum beta carotene levels (triggered protocol). RESULTS For almost the entire group (-99%), thyroid function tests were normal for age. IGF-1 levels were normal for 93% of the cohort. A total of 120 subjects, 89 HIV-positive and 31 HIV-negative, had an abnormality of growth, pubertal development, or both; 34 (11.1%) HIV-positive and 4 (3.6%) HIV-negative subjects had declines in height (p = .001), 20 (23.3%) HIV-positive and 5 (15.8%) HIV-negative subjects had not achieved Tanner stage 4 by 15 years of age (p = .372) and 59 (43.4%) HIV-positive and 23 (25.6) HIV-negative subjects had abnormal growth velocity (p < 0.001). Among subjects with abnormal height or growth velocity, the HIV-positive group had significantly lower mean age-adjusted testosterone levels than did the HIV-negative group (p = .030). Within the HIV-positive group, older subjects with abnormal height or growth velocity had significantly lower mean bone age than subjects of similar age without growth abnormalities (p = .0092). Extensive testing was done in 39 patients (32 HIV-positive, 7 HIV-negative). Half of the HIV-positive subjects had mean 12-hour growth hormone levels <3 ng/ml, 47% had peak stimulated levels <10 ng/ml, 28% had peak spontaneous values <10 ng/ml, and 38% had low levels of IGF-1. In the HIV-positive cohort, there was no difference in the rate of abnormalities of growth hormone secretion between those with CD4+ counts > or = or <200 cells/mm3 and between those subjects that met the 1987 Centers for Disease Control (CDC) surveillance definition of AIDS. In the subset of HIV-positive patients with abnormal peak growth hormone levels after clonidine stimulation, growth hormone response correlated positively with CD4+ count (r = .657, p = .0056) and beta carotene concentration (R = .596, p = .0192). CONCLUSIONS The results of this longitudinal study suggest that abnormalities of growth and pubertal development, particularly an abnormal growth velocity, are common in HIV-infected hemophilic boys and adolescents. These abnormalities might serve as indicators of the presence of HIV infection in this at-risk population. Since thyroid function tests and IGF-1 levels were normal, the etiology of growth impairment in HIV infection does not appear to be secondary to inadequate caloric intake or acquisition, or severe illness such as that caused by recurrent or persistent infection. Rather, HIV infection appears to lead to diminished growth hormone production or release and decreased androgen secretion, even before the development of AIDS and immunocompromise. These results provide a rationale for trials of treatment with growth hormone or androgens in patients with abnormalities of endocrine function.

Abstract
OBJECTIVE To evaluate the effect of megestrol acetate on weight gain and linear growth in human immunodeficiency virus-infected children with growth failure. METHODS All human immunodeficiency virus-infected children with growth failure treated with megestrol acetate at our institution were evaluated retrospectively. Weight, height, and weight:height ratio were documented from 6 months before initiation of megestrol acetate until 6 months after treatment was discontinued. Measurements were corrected for age and sex by conversion to z-scores. Incremental growth was determined before, during, and after treatment. The potential effects of CD4+ T-lymphocyte count and percentage, antiretroviral therapy, and intercurrent illnesses on growth were evaluated. RESULTS Nineteen patients were treated with a total of 27 courses of megestrol acetate. The median duration of therapy was 7 months (range, 3 to 11 months), and the median megestrol acetate dose was 7.91 mg/kg/day (range, 4.06 to 8.56 mg/kg/day). From 6 months and 3 months before treatment to the onset of therapy, median changes in weight z-scores were -.27 and -.15, respectively. During megestrol acetate treatment, median changes in weight z-scores were +.29 after 1 month of therapy, +.40 after 3 months, and +.57 after 6 months. After megestrol acetate therapy was discontinued, poor weight gain and weight loss resumed. Median 6-month growth velocities for weight were less than the 10th percentile before megestrol acetate, greater than the 97th percentile during treatment, and less than the 3rd percentile after treatment was discontinued. Megestrol acetate therapy was not associated with changes in linear growth. Antiretroviral therapy, CD4+ T-lymphocyte count or percentage, or intercurrent illnesses were not associated with statistically significant differences in response to megestrol acetate therapy. CONCLUSIONS Megestrol acetate treatment of growth failure in pediatric human immunodeficiency virus disease is associated with weight gain, without affecting linear growth.

Abstract
OBJECTIVE To determine the demographic/clinical profile of human immunodeficiency virus (HIV)-infected adolescents in care at selected sites. METHODS We mailed surveys requesting prevalence data from physicians in government-funded HIV research and care programs on HIV-infected youth (10-21 years) receiving care. RESULTS A total of 49% responses yielded information on 978 subjects. Vertical, blood, and sexual were predominant transmission modes. Three-quarters were of an ethnic/racial minority; 50% were female. The earliest median CD4 count was 0.467 x 10(9)/liter (467/microliter). Percent asymptomatic varied by transmission: vertical (16%), blood products (40%), male-male sexual (67%) and female-male sexual (M:73%) (F:74%). Clinical indicated Pneumocystis carinii pneumonia prophylaxis was differentially prescribed: vertical (96%), blood (89%), and sexually (male-male-47%) (female-male: M: 36% and F: 56%). Of these youth 78% are not represented in national AIDS case data. CONCLUSIONS Examination of numerator data from selected sites indicates three transmission-driven adolescent HIV epidemics with different characteristics. Minority youth are disproportionately represented; many vertically infected infants are surviving to adolescence; sexual activity is a significant transmission avenue. HIV-infected youth appear to enter care with considerable immunosuppression. Clinical profiles and treatment patterns appear to differ by transmission mode. Further study is needed on adolescent HIV disease progression and determinants of access to care and treatment.

Abstract
Developments in the prevention and treatment of HIV infection in pregnant women and their children are encouraging. Perinatal ZDV therapy can reduce the maternal-infant transmission rate by two thirds in select populations. New therapies and the development of diagnostic assays to monitor HIV viral burden have renewed hope that, by aggressively controlling viremia, the progressive immunodeficiency can be delayed or even prevented. The general pediatric approach of preventing illnesses through aggressive vaccination and education policies must be actively incorporated into an approach to this epidemic. Success in controlling the pediatric HIV epidemic requires a concerted, coordinated effort by public policy makers, health care providers, basic science researchers, and those who are HIV-infected.

Abstract
HIV infection has profound effects on a patient's nutritional status because it can modulate appetite, nutrient absorption and basal metabolic rate. In addition, HIV infection can lead to the depletion of a variety of vitamins and micronutrients including vitamins A, D, B2, B6, B12, L-carnitine, iron, zinc and selenium. This review article summarizes existing data regarding nutritional defects in HIV-infected patients and the results of clinical studies addressing the effects of nutritional supplementation in infected patients.

Abstract
Children with human immunodeficiency virus (HIV) infection have a higher prevalence of intestinal malabsorption. Anemia is also a common feature in these children. The aims of this work were (a) to establish the prevalence of iron deficiency in HIV-infected children, (b) to test the hypothesis that iron deficiency is related to intestinal malabsorption, (c) to see whether it may contribute to anemia, and (d) to evaluate the sensitivity of oral iron load in the investigation of intestinal function. To accomplish these goals, 71 HIV-infected symptomatic children were enrolled. Iron serum values were determined before and after oral load with ferrous sulfate. The correlation between basal and post-load iron levels was evaluated by linear regression. Xylose level after oral load, fecal fat, and fecal alpha 1-antitrypsin concentration were also determined. Iron deficiency was detected in 48% of patients, and it was significantly associated with intestinal iron malabsorption. Sugar malabsorption, steatorrhea, and fecal protein loss were detected in 26, 36, and 17% of patients, respectively. Low hemoglobin levels were detected in 66% of patients. The majority of children with iron deficiency also had anemia. Preliminary data showed that oral iron administration was sufficient for raising hemoglobin in children with normal iron absorption, whereas parenteral administration was required in those with iron malabsorption. We conclude that (a) iron deficiency is a major feature of pediatric HIV infection, (b) it is related to intestinal malabsorption, and (c) it contributes to anemia. Finally, oral iron load is a sensitive test for investigating intestinal function.

Abstract
OBJECTIVE To evaluate the nature and magnitude of the effect of congenitally or perinatally acquired human immunodeficiency virus (HIV) infection on somatic growth from birth through 18 months of age. STUDY DESIGN Anthropometry was performed serially in 282 term infants born to HIV-infected women in a multicenter prospective natural history cohort study. Repeated measures analysis was used to compare z-score anthropometric indexes of weight-for-age, length-for-age, weight-for-length, and head circumference-for-age between infected and uninfected infants, with adjustment for covariates including infant gender; maternal education; prenatal alcohol, tobacco, and/or illicit drug exposure; and mean prenatal CD4+ T-lymphocyte count. A separate repeated measures model was used to assess the effect of infant zidovudine treatment on growth. RESULTS Infants infected with HIV were an estimated average 0.28 kg lighter and 1.64 cm shorter than uninfected infants at birth, were 0.71 kg lighter and 2.25 cm shorter by 18 months of age, and had a sustained estimated average decrement of 0.70 to 0.75 cm in head circumference. Patterns of growth were similar in male and female infants. Infected infants had a progressive decrement in body mass index from birth through 6 months of age. Infection with HIV was associated with significant decrements across all standardized growth outcome measures after adjustment for covariates. Mean z scores were lower for weight by 0.612 (p < 0.001), for length by 0.735 (p < 0.001), for weight-for-length by 0.255 (p = 0.02), and for head circumference by 0.563 (p < 0.001) SD units compared with uninfected infants. Zidovudine treatment was not associated with improved growth. CONCLUSION The effect of congenitally or perinatally acquired HIV infection on infant growth is one of early and progressive decrements in attained linear growth and growth in mass, early and sustained decrements in head growth, and marked early decrements in body mass index.

Abstract
We evaluated the growth pattern, bone age, insulin-like growth factor I (IGF I) secretion and thyroid function in 24 perinatally infected children: 9 asymptomatic or paucisymptomatic (group 1) and 15 with a more advanced disease state and treated with zidovudine (group 2). Statural and ponderal growth were compared with those of 37 at-risk children who seroreverted. During the two-year follow-up, 22% of children in group 1 had impaired growth, 33% bone age delay, 45% reduced IGF I levels but none had thyroid dysfunction. In group 2, 53% had growth failure, 53% bone age delay, 86% reduced IGF I levels and 40% thyroid dysfunction. Among seroreverters, none showed growth impairment; statistically significant differences were found for height, weight and height velocity between perinatally infected children and seroreverters. Since auxological and hormonal evaluations run parallel to the clinical course of infection, these indices may be useful in monitoring disease progression.

Abstract
As part of the Hemophilia Growth and Development Study, we investigated the impact of human immunodeficiency virus (HIV) infection on statural growth, weight gain, and skeletal and sexual maturity in more than 300 boys with moderate to severe hemophilia, of whom 62% were infected with HIV. Age-adjusted height and weight were reduced in the HIV-infected subjects (p < 0.001). However, mean weight for height and triceps skin-fold thickness of the infected-boys closely resembled those of the uninfected group. In HIV-infected boys, height for age was positively related to the CD4+ lymphocyte count when the count was < 200 cells/mm3. Age-adjusted serum testosterone levels did not differ by HIV status, but in the infected participants the mean age-adjusted bone age was significantly reduced (p = 0.038) and the distribution of Tanner stages, adjusted for age, differed significantly (p = 0.003). The probability of advancing one or more Tanner stages in the first study year was significantly slowed in HIV-infected boys more than 14 years of age (p = 0.0003). We conclude that linear growth was significantly impaired in boys with hemophilia and HIV infection, but the wasting of malnutrition was not found. The delays in bone age and pubertal maturation strongly suggest that part of the growth failure seen in acquired immunodeficiency syndrome can be attributed to pubertal delay. We speculate that the lack of demonstrable difference in age-adjusted testosterone concentrations might reflect subtle differences in the pattern of secretion of testosterone or in the concentration of sex-hormone binding globulin.

Abstract
Decreasing susceptibility to zidovudine (ZDV) has been described in persons infected with human immunodeficiency virus (HIV) type 1 who are receiving ZDV therapy. However, the clinical significance of decreased ZDV susceptibility remains unclear. In this study, HIV isolates obtained from children with symptomatic HIV infection treated with ZDV were monitored for their susceptibility to the antiretroviral agent and correlated with disease progression. Using a peripheral blood mononuclear cell-based assay to measure ZDV susceptibility, we evaluated HIV isolates from 19 children (mean age, 6.8 years; range, 5 months to 12 years) during ZDV therapy for susceptibility to ZDV. Of the 19 children studied, 10 continued to have susceptible HIV strains during ZDV treatment, and 9 acquired resistant viruses. All eight isolates from children without previous exposure to ZDV were initially susceptible. After a median of 11 months of ZDV therapy, three (38%) of these eight children had acquired resistant HIV strains (defined as ZDV susceptibility > or = 10 mumol/L). Children with resistant strains had worse clinical outcomes than children whose viruses remained susceptible, as determined by a 50% decline in absolute CD4+ cell counts after 1 year of treatment, failure to thrive, or death. Children with resistant viruses who were given alternative antiretroviral therapy frequently responded to the new treatment with improved growth and stabilization of their HIV-related disease. These data suggest that, in HIV-infected children, ZDV-resistant HIV strains are associated with diminished drug efficacy and more rapid disease progression.
