Abstract
OBJECTIVES The prevention of mother-to-child transmission of HIV has been a global success. But little is known about the growth parameters of infants delivered by mothers with HIV or the drug resistance of infants with HIV in China. The study aimed to assess growth parameters and drug resistance in Chinese infants exposed to HIV. METHODS We conducted an 18-month longitudinal follow-up study of 3283 infants (3222 without HIV; 61 with HIV) born to mothers with HIV in the Guangxi Zhuang Autonomous Region between January 2015 and December 2021. The weight and length of all participants was recorded. In addition, genetic subtypes and drug resistance analysis were performed for infants with HIV. RESULTS Compared with infants without HIV, those with HIV had significantly lower weight/length Z-scores, except at 18 months of age. The length/age Z-scores of infants with HIV was significantly reduced, except at 1 month of age. The weight/age Z-scores of infants with HIV were significantly lower at all follow-up time points. The weight/length Z-scores of male infants without HIV were significantly lower than for female infants without HIV at all follow-up time points. Male infants without HIV had lower length/age and weight/age Z-scores than female infants at the remaining follow-up points, except at 1 month of age. Of a total of 61 infants with HIV, subtype and drug-resistance data were obtained from 37 (60.66%) samples. Infants with HIV were dominated by the CRF01_AE genotype and showed a diversity of mutation sites dominated by non-nucleoside reverse transcriptase inhibitor resistance. CONCLUSION Our study demonstrates the growth of infants exposed to HIV in southwest China and provides detailed information on subtype distribution and drug resistance of those with HIV. Nutritional support and drug-resistance surveillance for infants exposed to HIV need to be strengthened.

Prevention of mother-to-child transmission of HIV in Kermanshah, west of Iran from 2014 to 2021. BMC Pediatr 2023; 23:29. [PMID: 36653794 PMCID: PMC9850679 DOI: 10.1186/s12887-022-03829-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2022] [Accepted: 12/28/2022] [Indexed: 01/20/2023] Open
Abstract
BACKGROUND This study aimed to evaluate the implementation of the prevention of mother-to-child transmission (PMTCT) of the HIV-PMTCT program in Kermanshah, west of Iran, from 2014 to 2021. METHODS The data of all HIV-infected mothers and their infants who were monitored by the Kermanshah behavioral diseases counseling center was extracted and recorded in a checklist. RESULTS Out of 95 included infant, 45 (47.4%) were girls and 50 (52.6%) were boys. The mothers were mostly infected with HIV via their infected spouse. The pregnancies of 77 cases (82.1%) were in accordance with the national guideline. The average length of treatment for this group was 185 days. Of the 18 mothers who did not receive treatment, nine were diagnosed during childbirth and nine had no available information. All infants born from infected mothers underwent after-birth-antiretroviral prophylaxis, and all remained healthy. There was no statistically significant relationship between the birth weight and height of neonates with maternal age, maternal last viral load, disease stage, education, and maternal CD4 levels. Only a statistically significant relationship was observed between the duration of treatment and the infants' weight. CONCLUSION The results suggest the feasibility and effectiveness of the PMTCT program for HIV-positive mothers in Kermanshah. It seems that if pregnant HIV-positive women are diagnosed early and covered by a good prevention program on time, the risk of HIV to their babies will be reduced, significantly.

Ndiokwelu CO, Uwaezuoke SN, Iloh KK. Physical growth and sexual maturation of perinatally HIV-infected adolescent males in a southeast Nigerian tertiary hospital: a comparative cross-sectional study. BMC Pediatr 2022; 22:573. [PMID: 36199047 PMCID: PMC9533491 DOI: 10.1186/s12887-022-03626-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/11/2022] [Revised: 08/05/2022] [Accepted: 09/08/2022] [Indexed: 11/26/2022] Open
Abstract
Background The advent of highly-active anti-retroviral therapy (HAART) has resulted in the survival of children with Human Immunodeficiency Virus (HIV)/Acquired Immune Deficiency Syndrome (AIDS) into adolescence. Their prolonged survival has translated into co-morbidities like endocrine deficiencies which may manifest as growth and pubertal delay. This study aimed to determine the physical growth and sexual maturation of perinatally HIV-infected adolescent males and compare them with those of age-matched HIV-negative controls. Methods We conducted a comparative cross-sectional study of 104 perinatally HIV-infected males on HAART aged 10 to 19 years, and 104 age-matched HIV-negative males who served as controls. The subjects and controls were enrolled and assessed at a Nigerian tertiary hospital over six months. Anthropometric measurements such as weight, height, and BMI were obtained and Z scores for age were derived for weight, height, and BMI to determine physical growth using WHO AnthroPlus software. Sexual maturation was assessed using the method proposed by Marshall and Tanner. Data analysis and appropriate statistics were conducted with the Statistical Package for Social Sciences (SPSS) version 25 Chicago IL. A p-value < 0.05 was adopted as the level of statistical significance. Results The mean height, weight, and BMI Z scores of the subjects were all lower than those of the controls. The difference between the mean weight of the subjects (44.60 ± 13.32 kg) and the controls (49.97 ± 13.58 kg) was statistically significant (t = 2.88, p = 0.004). Similarly, the difference between the mean BMI Z-scores of the subjects (-0.96 ± 1.95) and the controls (-0.10 ± 0.86) was statistically significant (t = 4.10, p = < 0.001). The subjects showed a delay in pubic hair and testicular development for Stages 1, 2, and 3. Duration of HAART did not significantly affect the BMI of subjects who were in three groups: undernutrition, normal nutrition, and overnutrition (Kruskal-Wallis test, p = 0.30). Conclusion Perinatal HIV infection negatively affects physical growth and the onset of pubic-hair development (PH 2) despite the duration of HAART. We recommend that screening for weight deficit or pubertal delay should form part of the management protocol for HIV-infected male children on HAART.

Impact of HAART Therapy and HIV Infection over Fetal Growth-An Anthropometric Point of View. Microorganisms 2022; 10:microorganisms10061123.

Abstract
Human immunodeficiency virus (HIV) infection cannot be completely eliminated from the body because the virus integrates its genetic code into that of the host cell. The prevalence of pregnancy in women with HIV infection has increased due to the efficacy of antiretroviral therapy (ART). Placental insufficiency is associated with a reduction in blood flow and circulatory redistribution, resulting in fetal hypoxia and nutrient deprivation as a consequence of an altered placental function, and it can result in a lower birthweight. The aim of the study was to determine the combined effect of HIV infection and ART on the anthropometric parameters of infants born to HIV-positive pregnant women under ART compared to the values of these parameters in a control group of infants born to healthy mothers. There are no significant differences between the two groups in terms of gestational age at birth. We found a statistically significant lower birth weight in infants born from HIV-positive mothers under ART, with 3041 g in the control group compared to 2758 g in the group of HIV positive pregnant women (p < 0.01). There were statistically significant differences in all anthropometric parameters, these showing higher values in the control group (seronegative pregnant women).

Abstract
OBJECTIVE The aim of this study was to compare long-term growth between HIV-exposed uninfected children (CHEU) born to women with perinatally acquired HIV (CHEU-PHIV) and CHEU born to women with nonperinatally acquired HIV (CHEU-NPHIV). DESIGN A longitudinal analysis of anthropometric measurements from a U.S.-based multisite prospective cohort study enrolling CHEU and their mothers since April 2007. METHODS CHEU were evaluated for growth annually from birth through age 5 and again at age 7 years. Z-scores were calculated using U.S. growth references for weight (WTZ), height (HTZ), and weight-for-length or BMI-for-age (WLZ/BMIZ). Mid-upper arm circumference (MUACZ) and triceps skinfold thickness (TSFZ) Z-scores were obtained from ages 1 and 2, respectively, through age 7 years. Piecewise mixed-effects models, overall and stratified by race and sex, were fit to assess differential growth patterns across age by maternal PHIV status. RESULTS One thousand four hundred fifty-four singleton infants (286 CHEU-PHIV and 1168 CHEU-NPHIV) were included. CHEU-PHIV had slower growth rates than CHEU-NPHIV for WTZ and WLZ/BMIZ at earlier ages and continued to have lower mean WTZ [-0.27, 95% confidence interval (95% CI): -0.50, -0.04] and WLZ/BMIZ (-0.39, 95% CI: -0.67, -0.11) through age 7. Among non-Black boys, CHEU-PHIV had slightly lower WTZ and WLZ/BMIZ at birth than CHEU-NPHIV and these growth deficits persisted through age 7 years. CONCLUSION Compared with CHEU-NPHIV, CHEU-PHIV had diminished growth in early childhood with differences most pronounced among non-Black male children. Further longitudinal follow-up of CHEU-PHIV into young adulthood is needed to understand whether these early effects of maternal PHIV status on growth persist and have other health consequences.

Abstract
Single tablet regimens (STRs) have simplified antiretroviral therapy (ART) over the years in the adult human immunodeficiency virus (HIV) population. However, there is still a prevalent need to simplify regimens in children and adolescents living with HIV. Finding the optimal regimen requires a multi-factorial approach due to their complex pharmacokinetic profiles throughout childhood and the challenges and limitations of medication non-adherence in the pediatric population. These challenges include pill size, available formulations, palatability, and caregiver health literacy, which can all affect the proper administration of medications. The complexity of this population implies the importance of customizing everyone's antiretroviral regimen so that the patient and family can successfully adhere to the therapy. The current recommendations for ART in the adult and pediatric populations are similar, yet the use of STRs are limited. The goal of this review was to assess current data on available STRs and determine their utility as ART in the pediatric population.

Abstract
Advances in perinatal HIV management have averted a significant number of infections in neonates and have made the possibility of elimination of mother-to-child transmission a reality; however, significant gaps in implementation of early testing programs as well as the expansion of therapeutic strategies to neonates are hindering prevention efforts and access to safer, more effective and easier to administer treatment. This article provides insights on the current state of perinatal HIV, recent advances, and future needs.

Abstract
Abstract
Objective This study was aimed to determine if glutathione (GSH) deficiency occurs in children with HIV infection and whether GSH deficiency is associated with HIV-related short stature.
Methods We conducted a cross-sectional study with two age-matched comparison groups in an inner city hospital-based pediatric AIDS/HIV outpatient clinic. Ten perinatally HIV-infected children aged 6 to 49 months with short stature (height–age percentile ≤5) were studied together with age-matched 10 HIV-infected children with normal height and 10 HIV-seronegative children with normal height. Total erythrocyte GSH (GSH and GSH disulfide) levels were determined by a modification of the 5,5′-dithiobis-2-nitrobenzoic acid glutathione disulfide reductase method. Other measures included complete blood counts, lymphocyte subset analysis, plasma albumin, cholesterol, vitamins A and E, and determination of HIV disease stage.
Discussion Erythrocyte GSH levels were lower in HIV-infected children with short stature (mean ± standard deviation [SD]: 0.639 µmol/mL ± 0.189) compared with HIV-infected children with normal height (mean ± SD: 0.860 µmol/mL ± 0.358; p < 0.05) and HIV-negative controls (mean ± SD: 0.990 µmol/mL ± 0.343; p < 0.05). Plasma levels of cholesterol, albumin, and vitamins A and E did not differ between the short-stature group and either the HIV-infected normal-height group or HIV-negative controls.
Conclusion These results demonstrate a GSH deficiency in HIV-infected children with short stature and support the hypothesis that GSH balance is important in growth among HIV-infected children.

Abstract
Background With the increasing HIV seroprevalence among women of childbearing age in sub-Saharan Africa, limited data on growth outcomes of HIV exposed infants under current policies of universal maternal antiretroviral therapy exist. Methods The longitudinal growth patterns of 114 HIV exposed and unexposed infants were assessed and compared. The prevalence and factors associated with malnutrition were established. Infants under prevention of mother to child transmission care were recruited at 6 weeks post-delivery as were their HIV unexposed counterparts. Weight and length measurements were recorded at birth, 6 and 16 weeks postpartum. Results HIV vertical transmission rate was 8.8%. HIV exposed infants had significantly lower mean birth weights compared to HIV unexposed infants (2.9 ± 0.3; 3.2 ± 0.5; P < .001) respectively. Mean weight/length-for-age z-scores for HIV exposed, uninfected (HEU) infants were significantly below those of the HIV unexposed infants during follow up. By 6 weeks of age, 28.5% of HEU infants were malnourished while no malnutrition was evident in HIV unexposed infants. A gestational age <37 weeks (OR: 3.83; 95% CI: 1.03-14.30; P = .045) and HIV exposure (OR: 1.62; 95% CI: 0.17-15.73; P = .017) substantially increased the risk of stunting. Conclusion Growth deficits were witnessed in HIV exposed infants compared to HIV unexposed infants. There is need for early nutritional monitoring and support among HIV exposed infants.

Abstract
BACKGROUND Exposures to human immunodeficiency (HIV) and antiretroviral therapy in utero may have adverse effects on infant growth. Among children born in Denmark and aged 0-5 years, we aimed to compare anthropometric outcomes in HIV-exposed but uninfected (HEU) children with those in children not exposed to HIV. METHODS In a nationwide register-based study we included all singleton HEU children born in Denmark in 2000-2016. HEU children were individually matched by child sex, parity, and maternal place of birth to 5 singleton controls born to mothers without HIV. Weight-for-age z (WAZ) scores, length-for-age z (LAZ) scores, and weight-for-length or body mass index-for-age z scores were generated according to the World Health Organization standards and the Fenton growth chart for premature infants. Differences in mean z scores were analyzed using linear mixed models, both univariate and adjusted for social and maternal factors. RESULTS In total, 485 HEU children and 2495 HIV-unexposed controls were included. Compared with controls, HEU children were smaller at birth, with an adjusted difference in mean WAZ and LAZ scores of -0.29 (95% confidence interval [CI], -.46 to -.12) and -0.51 (95% CI, -.71 to -.31), respectively (both P ≤ .001). Over time, there was a trend toward increasing WAZ and LAZ scores in HEU children, and there was no significant difference in adjusted WAZ scores after age 14 days (-0.13 [95% CI, -.27 to .01]; P = .07) and LAZ scores after age 6 months (-0.15 [95% CI, -.32 to .02]; P = .08). CONCLUSION Compared with a matched control group, HEU children were smaller at birth, but this difference decreased with time and is not considered to have a negative effect on the health and well-being of HEU children during early childhood.

Brain microstructural changes support cognitive deficits in HIV uninfected children born to HIV infected mothers. Brain Behav Immun Health 2020; 2:100039. [PMID: 34589830 PMCID: PMC8474176 DOI: 10.1016/j.bbih.2020.100039] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2019] [Revised: 01/20/2020] [Accepted: 01/24/2020] [Indexed: 12/22/2022] Open
Abstract
Introduction Antiretroviral therapy (ART) is considered the most effective way to prevent perinatal transmission of human immunodeficiency virus (HIV). However, there is little knowledge about the effect of ART on the brain of HIV uninfected children born to HIV infected mothers (HUC). The current study evaluated the brain's microstructural integrity, and cognitive function in HUC compared to healthy children born to normal mothers (CHNM) and HIV infected children born to HIV infected mothers (HIC) to investigate the effect of in-utero exposure of ART on cerebral gray and white matter. Materials and methods Forty nine HIC, 12 HUC and 18 CHNM underwent neuropsychological (NP) assessment and a brain MRI. Diffusion tensor imaging (DTI) data was used to generate fractional anisotropy (FA) and mean diffusivity (MD) maps. Voxel wise comparison for FA and MD was performed between three groups using an analysis of covariance (ANCOVA) including age and sex as covariates, and correction for multiple comparisons (false discovery rate (FDR), p < 0.05 with minimum extended cluster size, 150 voxels). NP test scores were also compared between three groups using ANOVA with Post Hoc Bonferroni multiple comparison corrections (p < 0.05). Significantly changed FA and MD values in different brain regions in HIC and HUC compared to CHNM were used for correlation analysis with NP test scores using Pearson's correlation. Results HIC and HUC groups showed significantly decreased NP test scores in various domain compared to CHNM. Significantly lower NP test scores was observed in HIC than those of HUC. HIC showed decreased FA and increased MD in multiple brain sites as compared to both CHNM and HUC. Decreased FA along with both increased and decreased MD in different brain regions was present in HUC compared to CHNM. Both positive and negative correlation of altered FA and MD values from different brain regions in HIC and HUC with NP test scores was observed. Conclusion The presence of brain tissue changes and neurocognitive function deficit in absence of HIV infection in HUC indicates that ART may have a detrimental impact on the developing brain. The findings of the current study underscore the need for screening of ART exposed children for neurodevelopment and cognitive abnormalities at an early stage and call for access to early interventions, and nutritional and care programs.

Abstract
Background To evaluate the early growth (weight and length) of HIV-exposed uninfected (HEU) children from the prevention of mother-to-child transmission (PMTCT) of human immunodeficiency virus (HIV) program in Guangdong Province, China. Methods A total of 731 HEU children were longitudinally followed up at 7 time points, with anthropometric measurement conducted of weight and length (supine) in the first 18 months. Z scores were calculated, with and without adjustment for gestational age. Results A total of 708 HEU children were included in the final follow-up cohort, and 105 (14.83%) children completed all 7 follow-up visits. The mean of adjusted weight-for-age Z scores in these children was above zero and showed a decreasing trend in 18 months. The mean of adjusted length-for-age Z scores showed a decreasing trend and was above zero in the first 12 months; this declined to under zero at age 18 months. The proportion of underweight was 0.28–2.19% and that of stunting was 0.71–4.63% at each follow-up month-age. Slower growth in HEU children was associated with no sustained food subside after 6 month, mothers’ hemoglobin content less than 100 g/L during pregnancy, preterm birth, and low birth weight (p < 0.05). Conclusions HEU children could catch up to WHO growth standards in first 18 months in Guangdong; however, growth declined after 12 months, and these children need sustained nutritional support.

Impact of antiretroviral treatment on height evolution of HIV infected children. BMC Pediatr 2019; 19:287. [PMID: 31421667 PMCID: PMC6697969 DOI: 10.1186/s12887-019-1663-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/28/2019] [Accepted: 08/07/2019] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND Antiretroviral treatment (ART) has been shown to have a beneficial effect on the weight evolution but its effect on height remains unclear. We described patterns of height evolution and identified predictors of catch-up growth in HIV-infected children on ART. METHODS To describe the height evolution from birth to adulthood, we developed a nonlinear mixed effect model using data from perinatally HIV-infected children who initiated ART from 1999 to 2013 in a prospective cohort study in Thailand. The main covariates of interest were: sex, ART regimen (dual nucleoside reverse-transcriptase inhibitor, non-nucleoside reverse transcriptase inhibitor (NNRTI)-, or protease inhibitor (PI)-based), baseline CD4 percentage, HIV-RNA load and CDC HIV Classification stage and occurrence of AIDS-defining events. RESULTS A total 477 children (43% boys) contributed 18,596 height measurements over a median duration of 6.3 years on ART (interquartile range, 3.0 to 8.3). At ART initiation, median age was 6.2 years (1.8 to 9.6), 16% of children were underweight (weight-for-age z-score < - 2), 49% presented stunting (height-for-age z-score < - 2), and 7% wasting (weight-for-height z-score < - 2). The most frequent regimen at ART initiation was NNRTI-based (79%). A model with 4 components, birth length and 3 exponential functions of age accounting for the 3 growth phases was developed and show that the height-growth velocity was inversely associated with the age at ART initiation, the adult height was significantly lower in those who had experienced at least one AIDS-defining event while, as expected, the model found that adult height in females was lower than in males. Age at ART initiation, type of ART regimen, CDC stage, CD4 percentages, and HIV-RNA load were not associated with the final height. CONCLUSIONS The younger the children at ART initiation, the greater the effect on height-growth velocity, supporting the World Health Organization's recommendation to start ART as early as possible. However, final adult height was not linked to the age at ART initiation.

Birth size and early pneumonia predict linear growth among HIV-exposed uninfected infants. MATERNAL AND CHILD NUTRITION 2019; 15:e12861. [PMID: 31222958 DOI: 10.1111/mcn.12861] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/18/2019] [Revised: 06/05/2019] [Accepted: 06/06/2019] [Indexed: 12/27/2022]
Abstract
Stunting remains a global health priority, particularly in sub-Saharan Africa. Identifying determinants of linear growth in HIV-exposed uninfected (HEU) infants can inform interventions to prevent stunting in this vulnerable population. HIV-infected mothers and their uninfected infants were followed monthly from pregnancy to 12-month post-partum in Nairobi, Kenya. Mixed-effects models estimated the change in length-for-age z-score (LAZ) from birth to 12 months by environmental, maternal, and infant characteristics. Multivariable models included factors univariately associated with LAZ. Among 372 HEU infants, mean LAZ decreased from -0.54 (95% confidence interval [CI] [-0.67, -0.41]) to -1.09 (95% CI [-1.23, -0.96]) between 0 and 12 months. Declines in LAZ were associated with crowding (≥2 persons per room; adjusted difference [AD] in 0-12 month change: -0.46; 95% CI [-0.87, -0.05]), use of a pit latrine versus a flush toilet (AD: -0.29; 95% CI [-0.57, -0.02]), and early infant pneumonia (AD: -1.14; 95% CI [-1.99, -0.29]). Infants with low birthweight (<2,500 g; AD: 1.08; 95% CI [0.40, 1.76]) and birth stunting (AD: 1.11; 95% CI [0.45, 1.78]) experienced improved linear growth. By 12 months of age, 46 infants were stunted, of whom 11 (24%) were stunted at birth. Of the 34 infants stunted at birth with an available 12-month LAZ, 68% were not stunted at 12 months. Some low birthweight and birth-stunted HEU infants had significant linear growth recovery. Early infant pneumonia and household environment predicted poor linear growth and may identify a subgroup of HEU infants for whom to provide growth-promoting interventions.

Abstract
BACKGROUND Evidence on the association between breastfeeding and later childhood obesity and blood pressure (BP) is inconsistent, especially in HIV-prevalent areas where, until recently, HIV-infected women were discouraged from breastfeeding, but obesity is increasingly prevalent. METHODS AND FINDINGS The Siyakhula cohort (2012-2014), a population-based prospective cohort study, collected data over 3 visits on HIV-negative children ages 7 to 11 years in rural South Africa. We used weight (body mass index [BMI]), fat, and BP as outcome variables and incorporated early life (including mother's age at delivery and HIV status) and current life factors (including maternal education and current BMI). Our primary exposure was breastfeeding duration. We dichotomized 3 outcome measures using pre-established thresholds for clinical interpretability: (1) overfat: ≥85th percentile of body fat; (2) overweight: >1 SD BMI z score; and (3) prehypertension: ≥90th percentile for systolic BP (SBP) or diastolic BP (DBP). We modelled each outcome using multivariable logistic regression, including stopping breastfeeding, then early life, and finally current life factors. Of 1,536 children (mean age = 9.3 years; 872 girls; 664 boys), 7% were overfat, 13.2% overweight, and 9.1% prehypertensive. Over half (60%) of the mothers reported continued breastfeeding for 12+ months. In multivariable analyses, continued breastfeeding between 6 and 11 months was associated with approximately halved odds of both being overfat (adjusted odds ratio [aOR] = 0.43, 95% confidence interval [CI] 0.21-0.91, P = 0.027) and overweight (aOR = 0.46, CI 0.26-0.82, P = 0.0083), but the association with prehypertension did not reach statistical significance (aOR = 0.72, CI 0.38-1.37, P = 0.32). Children with a mother who was currently obese were 5 times more likely (aOR = 5.02, CI 2.47-10.20, P < 0.001) to be overfat and over 4 times more likely to be overweight (aOR = 4.33, CI 2.65-7.09, P < 0.001) than children with normal weight mothers. Differences between HIV-exposed and unexposed children on any of the outcomes were minimal and not significant. The main study limitation was that duration of breastfeeding was based on maternal recall. CONCLUSIONS To our knowledge, this is the first study examining and quantifying the association between breastfeeding and childhood obesity in an African setting with high HIV prevalence. We observed that breastfeeding was independently associated with reduced childhood obesity for both HIV-exposed and unexposed children, suggesting that promoting optimal nutrition throughout the life course, starting with continued breastfeeding, may be critical to tackling the growing obesity epidemic. In the era of widespread effective antiretroviral treatment for HIV-infected women for life, these data further support the recommendation of breastfeeding for all women.

Abstract
Objectives. Prevention of mother-to-child HIV transmission has been globally successful leading to a decline in HIV-infected infants. Thus, the number of HIV-exposed, but uninfected, infants is increasing. As growth is an important indicator of child health, this study aimed to evaluate growth parameters of HIV-exposed Chinese infants. Methods. A prospective study was conducted among HIV-exposed (HIV-infected and uninfected) infants born during 2007 to 2015 in Liuzhou, China. Their weight and length were assessed longitudinally from birth to 18 months of age and compared with HIV-unexposed, uninfected (HUU) infants from the same region. Results. There were 467 HIV-exposed infants. Four percent of infants were HIV-infected. The mean weight-for-age (WAZ) and length-for-age (LAZ) z scores of HIV-infected infants were significantly lower than those of HIV-exposed but uninfected (HEU) infants during 9 to 18 months and 12 to 18 months of age, respectively. Additionally, the mean WAZ and LAZ scores of HIV-infected infants were significantly lower than HUU infants during the first 12 months and 18 months of life, respectively. The mean WAZ and LAZ scores of HEU infants were significantly lower than HUU infants during the first 12 months and 6 months of life, respectively. HEU infants also had a lower mean weight-for-length z score than HUU infants during the first 6 months. Conclusion. We demonstrated poor growth among HIV-exposed Chinese infants, including HIV-uninfected, compared with HUU infants. The results emphasize the need for nutritional monitoring and interventions for HIV-exposed infants regardless of HIV infection status. Research is needed on long-term growth trajectories and factors affecting growth of HIV-exposed infants in China.

Abstract
BACKGROUND There are currently two markers used to monitor treatment response to anti-retroviral therapy (ART) in HIV-infected children: CD4 T-cell count and HIV viral load; but analysis of these could be challenging in resource-poor countries. The aim of this study was therefore to determine whether change in growth parameters such as weight-for-age Z score (WAZ), height-for-age Z score (HAZ) and body mass index-for-age Z score (BMIZ) is associated with treatment response in HIV-infected children. METHODS This was a nested case-control study, in which the data were collected at enrolment and then periodically every 6 months for a total 36 month follow up of 107 HIV-infected children enrolled and treated at National Hospital of Pediatrics, Vietnam. RESULTS At treatment initiation, WAZ, HAZ and BMIZ were not significantly higher in the treatment success (TS) group compared with the treatment failure (TF) group. After ART initiation, WAZ and HAZ increased, and this was significant in the TS group (from -1.5 to -0.54, P < 0.01 and from -2.06 to -0.84, P < 0.01, respectively). Low HAZ was significantly associated with TF (HR, 0.71; 95% CI: 0.54-0.92). CONCLUSION Height-for-age Z score was the most sensitive growth parameter in prediction of the treatment response. In order to use growth parameters, particularly HAZ as a prognosis marker for TF in clinical practice, further research should be conducted to evaluate the role of growth parameters and their effects on treatment response.

Abstract
BACKGROUND HIV-exposed but uninfected (HEU) children may be at an increased risk of impaired growth when compared with their HIV-unexposed and uninfected (HUU) counterparts. We compared the growth patterns of HEU to HUU children in Nigeria. METHODS Pregnant women with and without HIV infection were enrolled at the Plateau State Specialist Hospital, Jos, Nigeria. Infants born to these mothers were recruited at birth and the mother-infant pairs followed up for 18 months. Weight, length and head circumference of the infants were measured at each visit. Age- and sex-standardized Z scores were generated for each anthropometric measure using the World Health Organization Child Growth Standards. Children with length-for-age, weight-for-age and weight-for-length Z scores <-2 were classified as stunted, underweight and wasted, respectively. RESULTS Of 415 children (307 HEU and 108 HUU) recruited for this study, 117 (28.4%), 9 (2.2%) and 32 (7.8%) infants were stunted, underweight and wasted, respectively, at birth. In a multivariable longitudinal analysis, the odds of stunting were higher among HEU as compared with HUU children [adjusted odds ratio: 2.4 (95% confidence interval: 1.4-4.1)]. Similarly, odds of being underweight were higher among the HEU children [adjusted odds ratio: 1.6 (95% confidence interval: 1.1-2.2)]. CONCLUSIONS Linear and ponderal growth were more impaired among HEU as compared with HUU children in Nigeria during the first 18 months of life. Further studies are needed to explore the causal basis for these differences.

Abstract
OBJECTIVES Human immunodeficiency virus infection can result in the early impairment of anthropometric indicators in children and adolescents. However, combined antiretroviral therapy has improved, in addition to the immune response and viral infection, the weight and height development in infected individuals. Therefore, the objective was to evaluate the effect of combined antiretroviral on the growth development of human immunodeficiency virus infected children and adolescents. SOURCE OF DATA A systematic review was performed. In the study, the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) strategy was used as the eligibility criterion. The MEDLINE-PubMed and LILACS databases were searched using these descriptors: HIV, children, growth, antiretroviral therapy. The objective was defined by the population, intervention, comparison/control, and outcome (PICO) technique. Inclusion and exclusion criteria were applied for study selection. SYNTHESIS OF DATA Of the 549 studies indexed in MEDLINE-PubMed and LILACS, 73 were read in full, and 44 were included in the review (33 showed a positive impact of combined antiretroviral therapy on weight/height development, ten on weight gain, and one on height gain in children and adolescents infected with human immunodeficiency virus). However, the increase in growth was not enough to normalize the height of infected children when compared to children of the same age and gender without human immunodeficiency virus infection. CONCLUSIONS Combined antiretroviral therapy, which is known to play a role in the improvement of viral and immunological markers, may influence in the weight and height development in children infected with human immunodeficiency virus. The earlier the infection diagnosis and, concomitantly, of malnutrition and the start of combined antiretroviral therapy, the lower the growth impairment when compared to healthy children.

Knockdown of host genes using high-throughput genome-wide RNA interference screens has identified numerous host factors that affect viral infections, which would be helpful in understanding host-virus interactions. We have developed a vhfRNAi web resource based on genome-wide RNAi experiments for viruses. It contains experimental details of 12 249 entries (host factors + restriction factors) for 18 viruses. Simultaneously, this resource encompasses analysis of overlapping genes, genome wide association studies, gene ontology (GO), pathogen interacting proteins, interaction networks and pathway enrichment. Using overlap analysis, it was found that Influenza A virus shared overlapping host genes with the majority of viruses including Hepatitis C virus and Dengue virus 2. In the genome wide association studies analysis, 429 diseases/traits were mapped, of which obesity-related traits were the most common. GO analysis revealed that the major categories belonged to metabolic processes, molecule transport, signal transduction, proteolysis, etc. In the pathogen interacting protein analysis, protein interaction data from different resources can be explored for further understanding of host-virus biology. By pathway enrichment analysis, a total of 8955 genes were mapped on 303 pathways with most of the hits coming from metabolic pathways. We have found 491 genes that are not essential for the host but essential for the virus and can be targeted to inhibit the virus. These may be explored as potential candidates for drug targets. The resource is freely accessible at and will be useful in understanding host-virus biology as well as identification of targets for the development of antiviral therapeutics.

Int J Dev Neurosci 2018; 65:66-82.

Abstract
Despite the availability of antiretroviral prophylactic treatment, pediatric human immunodeficiency virus type 1 (HIV-1) continues to be a significant risk factor in the post-cART era. The time of infection (i.e., during pregnancy, delivery or breastfeeding) may play a role in the development of neurocognitive deficits in pediatric HIV-1. HIV-1 viral protein exposure on postnatal day (P)1, preceding the postnatal brain growth spurt in rats, had deleterious effects on neurocognitive development and anatomical parameters of the hippocampus (Fitting et al., 2008a,b). In the present study, rats were stereotaxically injected with HIV-1 viral proteins, including Tat1-86 and gp120, on P10 to further examine the role of timing on neurocognitive development and anatomical parameters of the hippocampus (Fitting et al., 2010). The dose-dependent virotoxin effects observed across development following P10 Tat1-86 exposure were specific to spatial learning and absent from prepulse inhibition and locomotor activity. A relationship between alterations in spatial learning and/or memory and hippocampal anatomical parameters was noted. Specifically, the estimated number of neurons and astrocytes in the hilus of the dentate gyrus explained 70% of the variance of search behavior in Morris water maze acquisition training for adolescents and 65% of the variance for adults; a brain-behavior relationship consistent with observations following P1 viral protein exposure. Collectively, late viral protein exposure (P10) results in selective alterations in neurocognitive development without modifying measures of somatic growth, preattentive processing, or locomotor activity, as characterized by early viral protein exposure (P1). Thus, timing may be a critical factor in disease progression, with children infected with HIV earlier in life being more vulnerable to CNS disease.

Abstract
OBJECTIVES To describe prevalence and risk factors for wasting and stunting among HIV-infected children with a median duration of 3 years of antiretroviral therapy (ART) at the time of their enrollment in the cohort study. METHODS Wasting and stunting at ART initiation and enrollment were defined as weight-for-height/body mass index-for-age Z scores < -2 and height-for-age Z scores < -2, respectively. Logistic regression was used to assess risk factors for wasting and stunting. Main predictive factors were age at enrollment, nutritional status and age (< or ≥5 years) at ART initiation and ART duration (< or ≥3 years on first-line, or ≥3 years including a switch to second-line ART). RESULTS Two hundred forty-four children 2-16 years of age were enrolled. Overall, wasting and stunting prevalence dropped off consistently in children 2-10 years of age, between ART initiation and enrollment, while it remained at high levels, 52% and 42%, respectively, in children 10-16 years of age. Risk factors for wasting at enrollment were ART duration of ≥3 years including a switch to second-line [adjusted odds ratio (aOR): 3.9, 95% confidence interval (CI): 1.7-8.9] and wasting at ART initiation (aOR: 2.7, 95% CI: 1.4-5.2). The risk factor for stunting at enrollment was stunting at ART initiation (aOR: 11.6, 95% CI: 5.4-25.0), independent of ART duration. CONCLUSIONS Malnutrition at the time of ART initiation was the main predictor of malnutrition at enrollment among HIV-infected children on ART. Longer duration on ART had no overall protective effect on wasting and stunting. Growth and virologic monitoring are of utmost importance in the comprehensive care of children with HIV infection.

Abstract
Background Early growth of HIV-exposed, uninfected (HEU) children is poorer than that of their HIV-unexposed, uninfected (HUU) counterparts but there is little longitudinal or longer term information about the growth effects of early HIV exposure. Methods We performed a longitudinal analysis to compare growth of HEU and HUU infants and children using data from two cohort studies in Lusaka, Zambia. Initially 207 HUU and 200 HEU infants from the Breastfeeding and Postpartum Health (BFPH) study and 580 HUU and 165 HEU from the Chilenje Infant Growth, Nutrition and Infection Study (CIGNIS) had anthropometric measurements taken during infancy and again when school-aged, at which time 66 BFPH children and 326 CIGNIS children were available. We analysed the data from the two cohorts separately using linear mixed models. Linear regression models were used as a secondary analysis at the later time points, adjusting for breastfeeding duration. We explored when the main group differences in growth emerged in order to estimate the largest ‘effect periods’. Results After adjusting for socioeconomic status and maternal education, HEU children had lower weight-for-age, length-for-age and BMI-for-age Z-scores during early growth and these differences still existed when children were school-aged. Exposure group differences changed most between 1 and 6 weeks and between 18 months and ~7.5 years. Conclusions HEU children have poorer early growth than HUU children which persists into later growth. Interventions to improve growth of HEU children need to target pregnant women and infants.

Abstract
BACKGROUND Abnormal childhood growth may affect future health. Maternal tenofovir (TFV) use was associated with lower body length and head circumference at 1 year of age in HIV-exposed uninfected (HEU) US children. METHODS We studied 509 HEU children in the US-based Surveillance Monitoring of Antiretroviral Therapy Toxicities cohort whose HIV-infected mothers were not using antiretrovirals at the last menstrual period and began combination antiretroviral therapy (cART) in pregnancy (cART initiators). We examined adjusted associations between antiretrovirals and Centers for Disease Control 2000 growth Z scores at 2 years of age within trimester of cART initiation: weight (weight Z score), length (length Z score), weight-for-length [weight-for-length Z score (WFLZ)], triceps skinfold Z score (TSFZ) and head circumference (head circumference Z score). RESULTS Mothers mean age was 28.6 years; 57% were black non-Hispanic and 19% delivered at <37 weeks gestation. At 2 years, mean weight Z score, length Z score, WFLZ and head circumference Z score were above average (P < 0.05), whereas TSFZ (P = 0.57) did not differ from average. WFLZ was >1.64 standard deviation (SD) (>95th percentile) in 13%. Among children of first-trimester cART initiators, TFV+emtricitabine-exposed children had slightly higher mean WFLZ (0.45 SD; 95% confidence interval: -0.10 to 1.00) and lower TSFZ (-0.55 SD; 95% confidence interval: -1.07 to -0.02) compared with zidovudine+lamivudine-exposed children. TSFZ was lower in those exposed to boosted protease inhibitors. In contrast, growth in children of second trimester cART initiators did not differ by antiretroviral exposures. CONCLUSION Growth was above average in HEU; 13% were obese. Maternal TFV use was not associated with lower length or head circumference at 2 years of age, as hypothesized, but may be related to greater weight among those exposed to cART early in pregnancy.

Abstract
This study of a prospective and cross-sectional nature compared the motor and cognitive development of HIV-exposed and unexposed infants in their first 18months of age. 40 infants exposed to HIV and antiretroviral therapy (Experimental Group - EG) and 40 unexposed infants (Control Group - CG) participated in the study. They were divided into four age groups of 4, 8, 12 and 18months old, with 10 infants from EG and 10 from CG in each group. The infants were evaluated once on motor and cognitive development by the Bayley Scale of Infant and Toddler Development. Performance category grading and comparisons among scaled score, composite score and percentile rank were held. There was significant group effect for scores in motor and cognitive domains showing lower scores for EG regardless of age. In comparison to the CG, the EG presented lower scores for cognitive domain at 8 and 18months. In the performance categories, all infants were classified at or above the average for motor and cognitive development, except of one EG-18month old infant classified as borderline for motor development. Infants exposed to HIV and antiretroviral therapy own adequate cognitive and motor development in the first 18months. However, the lower scores found, particularly on the 8th and 18th month for cognitive development, may indicate future problems, highlighting the need for systematic follow-up of this population.

Abstract
BACKGROUND Sexually transmitted infections (STIs) in pregnancy such as Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) may lead to adverse infant outcomes. METHODS Individual urine specimens from HIV-infected pregnant women diagnosed with HIV during labor were collected at the time of infant birth and tested by polymerase chain reaction for CT and NG. Infant HIV infection was determined at 3 months with morbidity/mortality assessed through 6 months. RESULTS Of 1373 maternal urine samples, 277 (20.2%) were positive for CT and/or NG; 249 (18.1%) for CT, 63 (4.6%) for NG and 35 (2.5%) for both CT and NG. HIV infection was diagnosed in 117 (8.5%) infants. Highest rates of adverse outcomes (sepsis, pneumonia, congenital syphilis, septic arthritis, conjunctivitis, low birth weight, preterm delivery and death) were noted in infants of women with CT and NG (23/35, 65.7%) compared with NG (16/28, 57.1%), CT (84/214, 39.3%) and no STI (405/1096, 37%, P = 0.001). Death (11.4% vs. 3%, P = 0.02), low birth weight (42.9% vs. 16.9%, P = 0.001) and preterm delivery (28.6% vs. 10.2%, P = 0.008) were higher among infants of CT and NG-coinfected women. Infants who had any adverse outcome and were born to women with CT and/or NG were 3.5 times more likely to be HIV infected after controlling for maternal syphilis (odds ratio: 3.5, 95% confidence interval: 1.4-8.3). By adjusted multivariate logistic regression, infants born to mothers with any CT and/or NG were 1.35 times more likely to have an adverse outcome (odds ratio, 1.35; 95% confidence interval, 1.03-1.76). CONCLUSIONS STIs in HIV-infected pregnant women are associated with adverse outcomes in HIV-exposed infected and uninfected infants.

Abstract
AIM To evaluate the nutritional status of HIV seropositive children, aged 2-10 years with age - matched controls and examine the role of nutritional intervention and HRT on their growth indices. MATERIALS AND METHODS It was a cross-sectional study done at a HIV Clinic of a teaching hospital. Fifty six seropositive children (age 2-10 year) classified as cases, and 60 seronegative age - matched controls were taken. Demographic and anthropometric characteristics were collected via valid instruments. HIV grading and adherence to HRT were assessed by using validated questionnaires. RESULTS Of the cases majority (87.5%) were infected by vertical transmission from mother to child, the remaining were infected by blood transfusion out of which 1.78% were haemophiliacs and remaining were thalassaemics. The prevalence of underweight among cases was 64.3%, compared to prevalence of 61% among controls. The prevalence of stunting was 44.6% among cases, while the prevalence of severe stunting was 14.3%. The prevalence of wasting among cases was 30.35%, while 7% cases were severely wasted. Only 23.33% controls were wasted. There was a significant difference in the Height- for-age between cases and controls, in the age of 4 years, 5 years and 6 years (p-value <0.05). CONCLUSION There was a significant difference in the Height- for-age between cases and controls, in the age of 4 years, 5 years and 6 years, indicating the need for proper nutritional intervention and timely HIV antiretroviral therapy to prevent stunting.

Abstract
OBJECTIVE HIV-exposed but HIV-uninfected (HEU) children are widely considered at increased risk of mortality and morbidity. Recent advances in prevention of mother-to-child HIV transmission (PMTCT) strategies, incorporating life-long universal maternal antiretroviral therapy (ART, "Option B+") with extended breastfeeding, may improve HEU child health substantially. We critically reviewed reports of mortality/morbidity among HEU and HIV-unexposed (HU) children in sub-Saharan Africa. METHODS We searched Medline, EMBASE, CINAHL, PsycINFO, Academic Search Premier, Global Health & Psychosocial Instruments databases, conference abstracts, and reference lists for longitudinal studies from sub-Saharan Africa reporting mortality and clinical morbidity among HIV-uninfected children aged ≤10 years, by maternal HIV status. Studies were appraised by Newcastle-Ottawa Scale and ACROBAT-NRSI. Due to substantial heterogeneity of study designs, populations and results (I(2) = 75%), data were not synthesised. RESULTS We included 37 reports (28 studies, 11 164 HEU children); methodological and reporting quality were variable. Most reports came from settings without universal access to maternal ART (n = 35). Results were conflicting, with some studies indicating increased risk of mortality, hospitalisation and/or under-nutrition among HEU children, while others found no evidence of increased risk. In subanalyses, improved maternal health, ART use and breastfeeding were strongly protective for all outcomes. Only 39% (11/28) of studies adjusted for major confounders. Reports from settings using universal maternal ART with breastfeeding (n = 2) found no differences in growth or development but did not report mortality or infectious morbidity. CONCLUSIONS The existing literature provides little insight into HEU child health under recently adopted PMTCT strategies. There is a need for robust comparative data on HEU and HIV-unexposed child health outcomes under Option B+; optimising breastfeeding practices and increasing maternal use of ART should be urgent public health priorities.

Abstract
We analyzed final height of 273 perinatally HIV-infected Asian adolescents older than 18 years at their last clinic visit. By the World Health Organization child growth reference, 30% were stunted, but by the Thai child growth reference, 19% were stunted. Half of those who were stunted at antiretroviral therapy initiation remained stunted over time. Being male and having a low baseline height-for-age Z score of less than -1.0 were associated with low final height Z score.

Abstract
OBJECTIVE The effectiveness of leaf concentrate powder (LCP) as a nutritional supplement was established in trials conducted among adolescent girls and pregnant women in India. Here we evaluate LCP, compared with skimmed milk powder (SMP), as a supplement for antiretroviral-naïve children living with HIV in a sub-Saharan African country. DESIGN Randomized controlled, two-arm, 6-month trial comparing effects of isoproteic (5 g) LCP (10 g daily) and SMP (15 g daily) on HIV-1 viral load, CD4+ cell count/percentage, weight/height-for-age, general blood parameters, diarrhoea, respiratory and HIV-related opportunistic infections. SETTING Bujumbura and Kirundo, Burundi. SUBJECTS Eighty-three HIV-positive, antiretroviral-naïve children aged 5-14 years: median (range) CD4+ count, 716 (361-1690) cells/mm3; log10 HIV-1 viral load, 4·39 (1·79-6·00). RESULTS LCP was equivalent to SMP in relation to HIV-specific blood parameters and did not demonstrate superiority over SMP in relation to Hb. Three children in each arm (LCP, 7·1 % (3/42); SMP, 7·3 % (3/41)) proceeded to antiretroviral therapy because their CD4+ counts fell below 350 cells/mm3. Children in the LCP group reported higher levels of appetite and overall health at 6 months. There were no differences in clinical events or any other outcome measures. LCP was less palatable than SMP to the children in this population, but there were few negative perceptions of appearance, texture and taste. CONCLUSIONS LCP appears to be equivalent to SMP as a nutritional supplement in this population, despite slightly lower palatability. In relation to viral load and CD4+ count, equivalence may indicate no effect in either group. Effectiveness relative to no supplementation remains to be determined.

Abstract
Background Healthcare access and resources differ considerably between urban and rural settings making cross-setting generalizations difficult. In resource-restricted rural/semi-rural environments, identification of feasible screening tools is a priority. The objective of this study was to evaluate gestational anthropometry in relation to birth and infant growth in a rural/semi-rural Tanzanian prospective cohort of mothers and their infants. Methods Mothers (n = 114: 44 HIV-positive) attending antenatal clinic visits were recruited in their second or third trimester between March and November, 2012, and followed with their infants through 6-months post-partum. Demographic, clinical, and infant feeding data were obtained using questionnaires administered by a Swahili-speaking research nurse on demographic, socioeconomic, clinical, and infant feeding practices. Second or third trimester anthropometry (mid-upper arm circumference [MUAC], triceps skinfold thickness, weight, height), pregnancy outcomes, birth (weight, length, head circumference) and infant anthropometry (weight-for-age z-score [WAZ], length-for-age z-score [LAZ]) were obtained. Linear regression and mixed effect modeling were used to evaluate gestational factors in relation to pregnancy and infant outcomes. Results and discussion Gestational MUAC and maternal HIV status (HIV-positive mothers = 39 %) were associated with infant WAZ and LAZ from birth to 6-months in multivariate models, even after adjustment for infant feeding practices. The lowest gestational MUAC tertile was associated with lower WAZ throughout early infancy, as well as lower LAZ at 3 and 6-months. In linear mixed effects models through 6-months, each 1 cm increase in gestational MUAC was associated with a 0.11 increase in both WAZ (P < 0.001) and LAZ (P = 0.001). Infant HIV-exposure was negatively associated with WAZ (β = -0.65, P < 0.001) and LAZ (β = -0.49, P < 0.012) from birth to 6-months. Conclusions Lower gestational MUAC, evaluated using only a tape measure and minimal training that is feasible in non-urban clinic and community settings, was associated with lower infant anthropometric measurements. In this rural and semi-rural setting, HIV-exposure was associated with poorer anthropometry through 6-months despite maternal antiretroviral access. Routine assessment of MUAC has the potential to identify at-risk women in need of additional health interventions designed to optimize pregnancy outcomes and infant growth. Further research is needed to establish gestational MUAC reference ranges and to define interventions that successfully improve MUAC during pregnancy.

BMC Pediatr 2015; 15:66. [PMID: 26048411 PMCID: PMC4458018 DOI: 10.1186/s12887-015-0386-8] [Citation(s) in RCA: 42] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/27/2015] [Accepted: 05/27/2015] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Early growth and health of HIV-exposed, uninfected (HEU) children is poorer than that of their HIV-unexposed, uninfected (HUU) counterparts but there is little information about longer term effects of early HIV exposure. We previously recruited two cohorts of HEU and HUU Zambian infants and documented the poorer infant growth and health of the HEU compared to the HUU children. We followed up HEU and HUU children from these cohorts when they were school-aged and compared their growth, health, biochemical markers of acute or chronic disease, and school grades. METHODS We recruited 111 HEU and 279 HUU children aged 6-12 years. We measured anthropometry, determined health by questionnaire and clinical examination, viewed the child's most recent school report, and measured blood pressure, haemoglobin (Hb), HbA1c, glucose, cholesterol, and C-reactive protein (CRP). RESULTS Anthropometric measures were lower among HEU than HUU children, significantly so for hip circumference (age- and sex-adjusted difference -1.74 cm; 95% confidence interval (CI) -3.24, -0.24; P = 0.023) and mid-upper-arm circumference (adjusted difference -0.63 cm, 95% CI -1.23, -0.04; P = 0.037) and with borderline effects for body mass index, thigh circumference and subscapular skinfolds. HEU children had significantly lower total, trunk, and limb fat percentages. All anthropometric and body composition differences became non-significant after adjustment for sociodemographic variables which differed between HEU and HUU children. More HEU than HUU children reported minor illnesses and were prescribed medication at the time of visit. There were no differences in biochemical markers between groups. HEU children had lower math grades than HUU children even after adjustment for socioeconomic variables. CONCLUSIONS Although HEU children were smaller and had lower percent fat than HUU children, this appeared to be due mainly to their poorer socioeconomic status. Reasons for lower school grades require further research.

Abstract
OBJECTIVE To describe catch-up growth after antiretroviral therapy (ART) initiation among children living with human immunodeficiency virus (CLHIV), attending a private clinic in India. METHODS This is a retrospective analysis of data of CLHIV attending Prayas clinic, Pune, India. Height and weight z scores (HAZ, WAZ) were calculated using WHO growth charts. Catch-up growth post-ART was assessed using a mixed method model in cases where baseline and at least one subsequent follow-up HAZ/WAZ were available. STATA 12 was used for statistical analysis. RESULTS During 1998 to 2011, 466 children were enrolled (201 girls and 265 boys; median age = 7 y). A total of 302 children were ever started on ART; of which 73 and 76 children were included for analysis for catch up growth in WAZ and HAZ respectively. Median WAZ and HAZ increased from -2.14 to -1.34 (p = 0.007) and -2.42 to -1.94 (p = 0.34), respectively, 3 y post ART. Multivariable analysis using mixed model (adjusted for gender, guardianship, baseline age, baseline WAZ/HAZ, baseline and time varying WHO clinical stage) showed gains in WAZ (coef = 0.2, 95 % CI: -0.06 to 0.46) and HAZ (coef = 0.49, 95 % CI: 0.21 to 0.77) with time on ART. Lower baseline WAZ/HAZ and older age were associated with impaired catch-up growth. Children staying in institutions and with baseline advanced clinical stage showed higher gain in WAZ. CONCLUSIONS The prevalence of stunting and underweight was high at ART initiation. Sustained catch-up growth was seen with ART. The study highlights the benefit of early ART in achieving normal growth in CLHIV.

Abstract
BACKGROUND CF infants often do not grow as expected which adversely affects later clinical outcomes, thus sensitive early measures of growth deficiency are important. This study compared attained growth for age with velocity standards to determine which better predicts growth deficits at 24 months of age. METHODS Growth deficiency in infancy based on weight and length velocity, and attained growth was calculated for 1992 infants in the US CF Foundation National Registry using the World Health Organization (WHO) and US growth standards. One, two and three month increments were used for calculating velocity and pooled for each age interval. Sensitivity and specificity of early indicators to predict growth deficiency at 24 months were calculated. RESULTS Observed prevalence of weight deficiency (<10th percentile) during the first year of life was 26.8% higher (95% CI=(25.6, 28.1%), p<0.001) on average when measured by attained weight for age than velocity. Attained weight for age at four months was a more sensitive predictor of diminished weight for age (<10th percentile) at 24 months (sensitivity=100%, 95% CI=(87, 100%)) than weight velocity (sensitivity=40%, 95% CI=(23, 59%)). Attained length at four months was more sensitive to detecting subsequent stunting (<10th percentile length for age) (77%, 95% CI=(62, 87%)) than length velocity (30%, 95% CI=(19, 45%)). CONCLUSIONS In CF infancy, attained weight or length is more sensitive than velocity-based definitions for predicting subsequent diminished growth.

Abstract
Growth failure is a common problem in many children with chronic diseases. This article is an overview of the most common causes of growth failure/growth retardation that affect children with a number of chronic diseases. We also briefly review the nutrition considerations and treatment goals. Growth failure is multifactorial in children with chronic conditions, including patients with cystic fibrosis, chronic kidney disease, chronic liver disease, congenital heart disease, human immunodeficiency virus, inflammatory bowel disease, short bowel syndrome, and muscular dystrophies. Important contributory factors to growth failure include increased energy needs, increased energy loss, malabsorption, decreased energy intake, anorexia, pain, vomiting, intestinal obstruction, and inflammatory cytokines. Various metabolic and pathologic abnormalities that are characteristic of chronic diseases further lead to significant malnutrition and growth failure. In addition to treating disease-specific abnormalities, treatment should address the energy and protein deficits, including vitamin and mineral supplements to correct deficiencies, correct metabolic and endocrinologic abnormalities, and include long-term monitoring of weight and growth. Individualized, age-appropriate nutrition intervention will minimize the malnutrition and growth failure seen in children with chronic diseases.

Abstract
Background Antiretroviral therapy (ART) reduces HIV-related mortality and morbidity substantially in children. The clinical characteristics, immunological and virological outcomes were evaluated in HIV-infected children receiving ART. Methods Twenty-six HIV-1-infected children receiving ART in Hubei province, China, were enrolled retrospectively in this study. During the period of ART, plasma viral load, lymphocyte phenotype of CD4 and CD8 cells and clinical events were assessed. Results The median duration of ART was 41 months (18–72.3 months). In children showing clinical improvement, high viral suppression rate below log10 (2.7) copies/ml by the third months of ART was observed. The median CD4 cell counts reached to 820.5/μl by 12 months and the median ratio of CD4/CD8 increased to 0.6 by 21 months. The counts of peripheral white blood cells and red blood cells decreased in the first 12 months, while Hb concentration, MCV and MCH increased (P < 0.001). Conclusions Despite the limited small sample size, ART is an effective strategy for inhibiting HIV replication and reconstructing the immunological response in children with AIDS.

Abstract
The use of raltegravir in treating HIV/AIDS has been proposed due to its effectiveness in suppressing high loads of HIV RNA in pregnant women, thus preventing infection of the fetus. However, administration of raltegravir during pregnancy produces a compound which is transferred to high concentrations to the offspring. The objective of this study is to evaluate the transplacental genotoxic effect of raltegravir in newborn rats. We evaluated the number of micronucleated erythrocytes (MNE), micronucleated polychromatic erythrocytes (MNPCE), and polychromatic erythrocytes (PCE) in the peripheral blood samples of the offspring of Wistar rats treated 6 days before birth with oral administration of raltegravir. The animals were randomly assigned to five groups as follows: raltegravir at doses of 15, 30, or 60 mg/day, cyclophosphamide 10 mg/kg (positive control), or 0.5 ml of sterile water (negative control). In addition, the effect of these drugs on the weight and height of newborns was assessed. There were no differences in the number of MNE, MNPCE, and PCE, and a slight decrease in the weight and height was observed in the offspring of the rat mothers treated with raltegravir. Genotoxicity studies are required in pregnant women to determine the risk of using raltegravir to the fetuses.

Abstract
BACKGROUND Despite a wide body of literature supporting the use of antenatal antiretrovirals (ARV) for the prevention of mother-to-child transmission, there remains a need for continued monitoring as the intrauterine interval is a critical period during which fetal programming influences the future health and development of the child. METHODS We conducted a systematic review of the current literature addressing potential metabolic complications of in utero HIV and ARV exposure. We describe studies evaluating metabolic outcomes such as intrauterine and early postnatal growth, bone health and mitochondrial toxicity. RESULTS Overall, infants exposed to HIV/ARV do not appear to exhibit vastly compromised intrauterine or early postnatal growth. However, some studies on the effect of combination antiretroviral therapy on small for gestational age and low birth weight outcomes in low-middle income countries show a risk for small for gestational age/low birth weight while those in the United States do not. Postnatal growth to 1 year does not appear to be affected by intrauterine tenofovir exposure in African studies, but a US study found statistically significant differences in length for age z scores (LAZ) at 1 year. Little data exists on long-term bone health. Mitochondrial toxicity including abnormal mitochondrial morphology and DNA content, as well as neurologic deficits and death, have been demonstrated in HIV/ARV-exposed infants. CONCLUSION Although gross measures of metabolic well-being appear to be reassuring, careful vigilance of even small risks for potential serious adverse effects to infants exposed to intrauterine HIV/ARVs is warranted as intrauterine fetal metabolic programming may substantially impact the future health of the child.

Abstract
We assembled a prospective cohort of 3144 human immunodeficiency virus (HIV) infected children aged <15 years initiating antiretroviral therapy (ART) in Dar es Salaam, Tanzania. The prospective relationships of baseline covariates with growth were examined using linear regression models. ART led to improvement in mean weight-for-age (WAZ), height/length-for-age (HAZ) and weight-for-length or body mass index (WLZ/BMIZ) scores. However, normal HAZ values were not attained over an average follow-up of 17.2 months. After 6 months of ART, underweight (P < 0.001), low CD4 count or percent (P < 0.001), stavudine containing regimens (P = 0.05) and advanced WHO disease stage (P < 0.001) at ART initiation were associated with better WAZ scores. Age >5 years on the other hand was associated with less increase in WAZ score after 6 months of ART (P < 0.001). These findings suggest that although ART improved the growth of the HIV-infected children in Tanzania, adjunct nutritional interventions may be needed to ensure that the growth of these children is optimized to the greatest extent possible.

Abstract
OBJECTIVES To describe 5-year growth, survival, and long-term safety among children exposed to nevirapine or zidovudine in an African perinatal prevention trial, HIVNET 012. METHODS All study children who were alive at the age 18 months were eligible for an extended follow-up study. Children whose families consented were enrolled and evaluated every 6 months from 24 to 60 months. At each visit, history, physical examination, and growth measures were taken. From these measurements, Z scores based on World Health Organization (WHO) standards were computed. Serious adverse event data were collected. Data from the initial and extended follow-up cohorts were included in the analysis. RESULTS Five hundred twenty-eight study children were alive at the age 18 months, and 491 (426 HIV uninfected and 65 infected) were enrolled into the follow-up study. Both exposed but uninfected children and HIV-infected children were substantially below WHO growth standards for weight and height. Head circumference Z scores for uninfected children were comparable with WHO norms. Five-year survival rates were 93% for uninfected children versus 43% for infected children. Long-term safety and growth outcomes in the 2 study arms were similar. CONCLUSIONS Both infected and uninfected children in the 5-year HIVNET 012 follow-up showed poor height and weight growth outcomes, underscoring the need for early nutritional interventions to improve long-term growth of all infants born to HIV-infected women in resource-limited settings. Similarly, the low 5-year survival among HIV-infected children support the importance of early initiation of antiretroviral therapy. Both peripartum nevirapine and zidovudine were safe.

Abstract
This cross-sectional study aimed to investigate the nutritional status and dietary intake of HIV-infected children and adolescents and the relationship between nutritional status and dietary intake and CD4(+) T-cell count and viral load. The sample was composed of 49 subjects aged 7-17 years and living in Florianópolis, Brazil. Nutritional status was assessed by height-for-age and body mass index-for-age. Dietary intake was assessed by a food frequency questionnaire. Spearman correlations and multiple linear regressions were used to determine the relationship between energy, nutrient intake and body mass index-for-age and CD4(+) T-cell count and viral load. The mean body mass index-for-age and height-for-age values were -0.26 ± 0.86 and -0.56 ± 0.92, respectively. The energy intake was 50.8% above the estimated energy requirement and inadequate intake of polyunsaturated fat, cholesterol, fibre, calcium and vitamin C was present in 100%, 57.1%, 40.8%, 61.2% and 26.5% of the sample, respectively. Multiple linear regression analyses revealed that energy intake was correlated with CD4+ T-cell count (r = 0.33; p = 0.028) and viral load (r = -0.35; p = 0.019). These data showed low body mass index-for-age and height-for-age z-scores, high energy intake and inadequate intake of important nutrients for immune function, growth and control of chronic diseases. A lower energy intake was correlated with viral suppression and immune preservation.

Abstract
OBJECTIVE To compare growth and body composition of uninfected children exposed to HIV with a contemporary HIV-unexposed group and to US references. STUDY DESIGN Uninfected children exposed to HIV under 2 years were enrolled into a longitudinal observational study and unexposed children under 2 years of age in a cross-sectional evaluation. Weights, lengths, head circumferences, skinfold thicknesses, and arm and thigh circumferences were measured and adjusted for age using Centers for Disease Control and National Health and Nutrition Examination Survey standards. Uninfected children exposed to HIV were compared with an unexposed nearest-neighbor matched comparison group. Uninfected children exposed to HIV were compared by age to Centers for Disease Control standards for growth measures and National Health and Nutrition Examination Survey standards for body composition. RESULTS One hundred eleven uninfected children exposed to HIV and 82 children not exposed to HIV were evaluated. For the matched comparison for both groups, the mean age was 10 months, 59% were male, and 73% were African American. No statistical differences were found in anthropometric measurements between uninfected children who were or were not exposed to HIV. Uninfected children exposed to HIV were smaller than US standards at birth with mean (SD) weight-for-age and weight-for-length z-scores of -0.39 (1.06); P = .002 and -0.35 (1.04); P = .005, respectively. Over the first 2 years of life, there was a trend toward increasing weight-for-age z-score, length-for-age z-score, and weight-for-length z-score in uninfected children exposed to HIV. Subscapular and triceps skinfolds among uninfected children exposed to HIV were lower than national standards and there was a trend that mid-upper arm circumference decreased over time. CONCLUSIONS Growth and body composition of uninfected children who were or were not exposed to HIV were similar. Uninfected children exposed to HIV weigh less at birth and show a pattern of slightly accelerated growth in the first 2 years of life. Uninfected children exposed to HIV had less subcutaneous fat and decreasing mid-upper arm circumference over time when compared with US standards.

Abstract
Infections with HIV represent a great challenge for the development of strategies for an effective cure. The spectrum of diseases associated with HIV ranges from opportunistic infections and cancers to systemic physiological disorders like encephalopathy and neurocognitive impairment. A major progress in controlling HIV infection has been achieved by highly active antiretroviral therapy (HAART). However, HAART does neither eliminate the virus reservoirs in form of latently infected cells nor does it completely reconstitute immune reactivity and physiological status. Furthermore, the failure of the STEP vaccine trial and the only marginal efficacies of the RV144 trial together suggest that the causal relationships between the complex sets of viral and immunological processes that contribute to protection or disease pathogenesis are still poorly understood. Here, we provide an up-to-date overview of HIV-host interactions at the cellular, the immune system and the neuroendocrine systems level. Only by integrating this multi-level knowledge one will be able to handle the systems complexity and develop new methodologies of analysis and prediction for a functional restoration of the immune system and the health of the infected host.

Abstract
Objective To assess the associations between maternal HIV infection and growth outcomes of HIV-exposed but uninfected infants and to identify other predictors for poor growth among this population. Design Within a trial of de-worming during pregnancy, the cohort of offspring was followed from birth. HIV status of the mothers and their children was investigated and growth data for children were obtained at age 1 year. Length-for-age, weight-for-age and weight-for-length Z-scores were calculated for each child; Z-scores <−2 were defined as stunting, underweight and wasting, respectively. Setting The study was conducted in Entebbe municipality and Katabi sub-county, Uganda. Subjects The sample consisted of 1502 children aged 1 year: HIV-unexposed (n 1380) and HIV-exposed not infected (n 122). Results Prevalence of stunting, underweight and wasting was 14·2 %, 8·0 % and 3·9 %, respectively. There was evidence for an association between maternal HIV infection and odds of being underweight (adjusted OR = 2·32; 95 % CI 1·32, 4·09; P = 0·006) but no evidence for an association with stunting or with wasting. Young maternal age, low maternal education, low birth weight, early weaning and experiencing a higher number of episodes of malaria during infancy were independent predictors for stunting and underweight. A higher number of living children in the family was associated with wasting. Conclusions Maternal HIV infection was associated with being underweight in HIV-exposed uninfected infants. The success of programmes for prevention of mother-to-child HIV transmission means that an increasing number of infants will be born to HIV-infected women without acquiring HIV. Therefore, viable nutritional interventions need to be identified for this population.

Abstract
Background Children born to HIV-infected women are susceptible to undernutrition, but modifiable risk factors and the time course of the development of undernutrition have not been well characterized. Objective To identify maternal, socioeconomic, and child characteristics that are associated with stunting, wasting, and underweight among Tanzanian children born to HIV-infected mothers, followed from 6 weeks for 24 months. Methods Maternal and socioeconomic characteristics were recorded during pregnancy, data pertaining to the infant’s birth were collected immediately after delivery, morbidity histories and anthropometric measurements were performed monthly. Multivariate Cox proportional hazards methods were used to assess the association between potential predictors and the time to first episode of stunting, wasting, and underweight. Results 2387 infants (54.0% male) were enrolled and followed for a median duration of 21.2 months. The respective prevalence of prematurity (<37 weeks) and low birthweight (<2500g) was 15.2% and 7.0%; 11.3% of infants were HIV-positive at 6 weeks. Median time to first episode of stunting, wasting, and underweight was 8.7, 7.2, and 7.0 months, respectively. Low maternal education, few household possessions, low infant birthweight, child HIV infection and male sex were all independent predictors of stunting, wasting, and underweight. In addition, preterm infants were more likely to become wasted and underweight, whereas those with a low Apgar score at birth were more likely to become stunted. Conclusion Interventions to improve maternal education and nutritional status, reduce mother-to-child transmission of HIV, and increase birth weight may lower the risk of undernutrition among children born to HIV-infected women.

Abstract
As prevention of mother-to-child HIV-1 transmission (PMTCT) programs decrease the numbers of HIV-1-infected infants, it remains important to improve growth in HIV-1-exposed, uninfected (EU) infants. To determine the growth rate and predictors of growth faltering in breast-fed and formula-fed EU infants, growth analyses [weight-for-age (WAZ), weight-for-length (WLZ), and length-for-age (LAZ) Z-scores] were conducted by using data from a randomized feeding trial in HIV-1-infected women in Kenya. Growth faltering in EU infants was compared based on randomization to breastfeeding (BF) or formula feeding (FF) using Cox proportional hazards regression models. Linear mixed-effects models determined rate and cofactors of length growth. Among 338 EU infants, 164 (49%) were breast-fed and 174 (51%) formula-fed. In both arms, growth declined steadily during follow-up. By 2 y, 29% of children were underweight (WAZ < -2), 18% were wasted (WLZ < -2), and 58% were stunted (LAZ < -2), with no differences by feeding arm. Higher maternal education (y) and taller stature (cm) were associated with a decreased risk of underweight and stunting [underweight: adjusted HR (aHR) = 0.90 (95% CI: 0.83, 0.99), P = 0.03, and aHR = 0.92 (95% CI: 0.87, 0.97), P = 0.002; and stunting: aHR = 0.91 (95% CI: 0.85, 0.97), P = 0.003, and aHR = 0.96 (95% CI: 0.92, 0.99), P = 0.02, respectively]. Diarrhea was associated with an increased risk of wasting [aHR = 2.26 (95% CI: 1.11, 4.62), P = 0.03]. In multivariate analyses, FF was associated with slower declines in length velocity [0.24 LAZ/y (95% CI: 0.06, 0.43), P = 0.009]. Despite being uninfected, HIV-1-exposed infants showed frequent growth faltering, suggesting the need for vigilance in recognizing stunting within PMTCT programs. The slower rate of decline in length growth with FF may reflect benefits of micronutrients. Because BF is the best option for HIV-1-infected mothers in resource-limited settings, nutritional interventions should be examined for their impact on growth in EU breast-fed infants.

Abstract
Human immunodeficiency virus vertical transmission in developed countries has dramatically decreased to less than 2% over the last 15 years due to the consecutive implementation of different prophylactic measures, including the use of antiretrovirals, elective cesarean section and refraining from breastfeeding. The follow-up of these otherwise healthy children is, by far, the most common situation related to HIV infection that general pediatricians currently face in routine clinical care in Spain. These recommendations issued by the Spanish Society of Pediatric Infectious Diseases attempt to summarize the main aspects of this follow-up, including birth management, type of feeding, neonatal antiretroviral prophylaxis, HIV infection diagnosis, common early comorbidities, short- and mid-term toxicities, vaccination and other prophylactic measures and long-term follow-up.
