Growth Trajectories Over the First Year of Life Among Early-Treated Infants with Human Immunodeficiency Virus and Infants Who are Human Immunodeficiency Virus-Exposed Uninfected. J Pediatr 2024; 270:114018. [PMID: 38508485 PMCID: PMC11176027 DOI: 10.1016/j.jpeds.2024.114018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2023] [Revised: 02/10/2024] [Accepted: 03/12/2024] [Indexed: 03/22/2024]
Abstract
OBJECTIVE To investigate the role of early antiretroviral therapy (ART) on growth trajectories of infants with human immunodeficiency virus (IHIV) in the first year of life. STUDY DESIGN As part of a clinical trial of early ART in Johannesburg, South Africa (2015-2018), 116 IHIV diagnosed within 48 hours of birth were started on ART as soon as possible, and 80 uninfected infants born to mothers living with HIV (IHEU) were enrolled. Both groups were followed prospectively from birth through 48 weeks and growth parameters collected. The groups were compared and risk factors for poor growth investigated, in the full cohort and among IHIV separately. RESULTS IHIV had lower mean weight-for-age Z-scores (WAZ) than IHEU at 4 and 8 weeks (-1.17 [SE:0.14] vs -0.72 [0.14], P = .035 and -1.23 [0.15] vs -0.67 [0.14], P = .012). Although there was some closing of the gap over time, means remained lower in IHIV through 48 weeks. In length-for-age Z-scores (LAZ), differences widened over time and IHIV had lower Z-scores by 48 weeks (-1.41 [0.15] vs -0.80 [0.18], P = .011). Deficits in WAZ and LAZ in IHIV vs IHEU were most marked among girls. IHIV with pre-ART viral load ≥1000 copies/ml had significantly lower weight-for-length and mid-upper arm circumference Z-scores across all time points through 48 weeks. CONCLUSIONS IHIV on early ART had deficits in WAZ over the first 8 weeks of life and lower LAZ at 48 weeks than IHEU. Among IHIV, higher pre-ART viral load was associated with worse anthropometric indicators through 48 weeks.

[PMID: 38628425 PMCID: PMC11019047 DOI: 10.4102/sajid.v39i1.589] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Accepted: 01/17/2024] [Indexed: 04/19/2024] Open
Abstract
Background Birth HIV point-of-care (POC) tests curtail analytical testing issues and expedite diagnosis, potentially allowing for earlier mother-infant pair engagement and improved outcomes. Many children are lost post antiretroviral therapy (ART) initiation within the first 6 months of follow-up. Objectives We compared 6-month retention in care, HIV viral load (VL) suppression and mortality among infants diagnosed with HIV at birth, using laboratory-based versus POC HIV PCR testing. Method From 2018 to 2019, infants exposed to HIV underwent birth HIV PCR POC testing at Kalafong Provincial Tertiary Hospital in Tshwane District. Their outcomes were compared to a historical control born between 2014 and 2016, who exclusively underwent laboratory-based HIV PCR testing. Both groups received comparable HIV care following national guidelines. Results Fifty-seven infants were studied (POC: 27; Control: 30). The POC turnaround time was significantly shorter (POC: 15.5 h [IQR: 4.3-24.7], Control: 68.3 h [IQR 46.0-93.9]; p = < 0.0001). Both populations had the same elapsed time from HIV diagnosis to ART initiation (median: 13 days, POC: IQR 8-21 days; Control: IQR 9-36 days). Six infants were never initiated (POC: 2 [7%]; Control: 4 [13%]). At 6 months, overall care retention was 72% (41/57), higher among the Control group (Control 23/30, 77%; POC: 18/27, 67%). HIV viral suppression at 6 months was higher among the POC group (POC: 14/18, 78%; Control: 9/19, 47%, p = 0.09). No deaths were reported. Conclusion Poor care retention at 6 months post ART initiation is concerning. Initial mother-infant visits should be effectively utilised to assess and manage potential risk factors for loss of follow-up. Contribution This study highlights the ongoing need to find workable solutions to improve retention in care, thereby ensuring the benefits of expedited HIV diagnosis and ART initiation.

Abstract
OBJECTIVES This study aimed to identify individual-level factors that affect malnutrition outcomes among children and adolescents living with HIV/AIDS in Tanzania. METHODS We used data from the National AIDS Control Programme. 70,102 participants aged 5 to 19 years attending care and treatment clinics between January to December 2021 were included. Nutritional assessments were performed by anthropometric measurement. Logistic regression models were used to evaluate risk factors. We further estimated marginal prevalence and adjusted predictions by marginal effects. Supplementary analysis assessed the accuracy of the final fitted model. RESULTS Prevalence of malnutrition for stunting, underweight, wasting, and anthropometric failure (CIAF) were 36.0%, 28.9%, 13.0%, and 48.0%, respectively. Several individual-level factors were significant determinants of malnutrition. Boys, participants aged 15-19 years, those switched to second- or third-line antiretroviral therapy (ART), initiated ART at ages of 5-14 years, ART duration less than 3 years, and were in advanced stages of WHO HIV clinical status had increased adjusted odds ratios and marginal prevalence. The larger AUC values for all models implied importance of identified factors accounted for malnutrition. CONCLUSIONS On long-term ART, nutritional interventions should be context-specific guidelines to improve growth, especially at ART initiation, ART regimen, and ART duration reckoning with age and sex.

Abstract
Significant advances in the field of HIV-1 therapeutics to achieve antiretroviral treatment (ART)-free remission and cure for persons living with HIV-1 are being made with the advent of broadly neutralizing antibodies and very early ART in perinatal infection. The need for HIV-1 remission and cure arises due to the inability of ART to eradicate the major reservoir for HIV-1 in resting memory CD4+ T cells (the latent reservoir), and the strict adherence to lifelong treatment. To measure the efficacy of these cure interventions on reservoir size and to dissect reservoir dynamics, assays that are sensitive and specific to intact proviruses are critical. In this review, we provided a broad overview of some of the key interventions underway to purge the reservoir in adults living with HIV-1 and ones under study in pediatric populations to reduce and control the latent reservoir, primarily focusing on very early treatment in combination with broadly neutralizing antibodies. We also summarized assays currently in use to measure HIV-1 reservoirs and their feasibility and considerations for studies in children.

[PMID: 36116479 DOI: 10.1016/s0140-6736(22)01492-1] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Revised: 07/24/2022] [Accepted: 08/02/2022] [Indexed: 01/16/2023]
Abstract
BACKGROUND Timely diagnosis and treatment of HIV is crucial in HIV-exposed infants to prevent the high rates of mortality seen during the first 2 years of life if HIV is untreated. However, challenges with sample transportation, testing, and result delivery to caregivers have led to long delays in treatment initiation. We aimed to compare the clinical effect of point-of-care HIV testing versus laboratory-based testing (standard of care) in HIV-exposed infants. METHODS We did a systematic review and meta-analysis and searched PubMed, MEDLINE, Cochrane Central Register of Controlled Trials, Embase, Conference Proceedings Citation Index-Science, and WHO Global Index Medicus, from Jan 1, 2014, to Aug 31, 2020. Studies were included if they pertained to the use of point-of-care nucleic acid testing for infant HIV diagnosis, had a laboratory-based nucleic acid test as the comparator or standard of care against the index test (same-day point-of-care testing), evaluated clinical outcomes when point-of-care testing was used, and included HIV-exposed infants aged younger than 2 years. Studies were excluded if they did not use a laboratory-based comparator, a nucleic acid test that had been approved by a stringent regulatory authority, or diagnostic-accuracy or performance evaluations (eg, no clinical outcomes included). Reviews, non-research letters, commentaries, and editorials were also excluded. The risk of bias was evaluated using the ROBINS-I framework. Data were extracted from published reports. Data from all studies were analysed using frequency statistics to describe the overall populations evaluated and their results. Key outcomes were time to result delivery and antiretroviral therapy initiation, and proportion of HIV-positive infants initiated on antiretroviral therapy within 60 days after sample collection. FINDINGS 164 studies were identified by the search and seven were included in the analysis, comprising 37 377 infants in total across 15 countries, including 25 170 (67%) who had point-of-care HIV testing and 12 207 (33%) who had standard-of-care testing. The certainty of evidence was high. Same-day point-of-care testing led to a significantly shorter time between sample collection and result delivery to caregivers compared with standard-of-care testing (median 0 days [95% CI 0-0] vs 35 days [35-37]). Time from sample collection to antiretroviral therapy initiation in infants found to be HIV-positive was significantly lower with point-of-care testing compared with standard of care (median 0 days [95% CI 0-1] vs 40 days [36-44]). When each study's result was weighted equally, 90·3% (95% CI 76·7-96·5) of HIV-positive infants diagnosed using point-of-care testing had started antiretroviral therapy within 60 days of sample collection, compared with only 51·6% (27·1-75·7) who had standard-of-care testing (odds ratio 8·74 [95% CI 6·6-11·6]; p<0·0001). INTERPRETATION Overall, the certainty of the evidence in this analysis was rated as high for the primary outcomes related to result delivery and treatment initiation, with no serious risk of bias, inconsistency, indirectness, or imprecision. In HIV-exposed infants, same-day point-of-care HIV testing was associated with significantly improved time to result delivery, time to antiretroviral therapy initiation, and proportion of HIV-positive infants starting antiretroviral therapy within 60 days compared with standard of care.

Abstract
BACKGROUND Control of the pediatric HIV epidemic is hampered by gaps in diagnosis and linkage to effective treatment. The 2015-2016 Malawi Population-based HIV impact assessment data were analyzed to identify gaps in pediatric HIV diagnosis, treatment, and viral load suppression. METHODS In half of the surveyed households, children ages ≥18 months to <15 years were tested using the national HIV rapid test algorithm. Children ≤18 months reactive by the initial rapid test underwent HIV total nucleic acid polymerase chain reaction confirmatory testing. Blood from HIV-positive children was tested for viral load (VL) and presence of antiretroviral drugs. HIV diagnosis and antiretroviral treatment (ART) use were defined using guardian-reporting or antiretroviral detection. RESULTS Of the 6166 children tested, 99 were HIV-positive for a prevalence of 1.5% (95% confidence intervals [CI]: 1.1-1.9) and 8.0% (95% CI: 5.6-10.5) among HIV-exposed children. The prevalence of 1.5% was extrapolated to a national estimate of 119,501 (95% CI: 89,028-149,974) children living with HIV (CLHIV), of whom, 30.7% (95% CI: 20.3-41.1) were previously undiagnosed. Of the 69.3% diagnosed CLHIV, 86.1% (95% CI: 76.8-95.6) were on ART and 57.9% (95% CI: 41.4-74.4) of those on ART had suppressed VL (<1000 HIV RNA copies/mL). Among all CLHIV, irrespective of HIV diagnosis or ART use, 57.7% (95% CI: 45.0-70.5) had unsuppressed VL. CONCLUSIONS Critical gaps in HIV diagnosis in children persist in Malawi. The large proportion of CLHIV with unsuppressed VL reflects gaps in diagnosis and need for more effective first- and second-line ART regimens and adherence interventions.

Abstract
BACKGROUND Poor growth and metabolic disturbances remain concerns for children living with HIV (CLHIV). We describe the impact of viral load (VL) on growth and lipid outcomes in South African CLHIV <12 years initiating World Health Organization recommended first-line antiretroviral therapy (ART) from 2012 to 2015. METHODS Z scores for length-for-age (LAZ), weight-for-age (WAZ) and body mass index-for-age were calculated. Lipids (total cholesterol, low-density lipoprotein and high-density lipoprotein) were measured. Hemoglobin A1C ≥5.8 was defined as at risk for type 2 diabetes. Mixed effects models were used to assess the association of VL at ART initiation with Z scores and lipids over time. RESULTS Of 241 CLHIV, 151 (63%) were <3 years initiating LPV/r-based ART and 90 (37%) were ≥3 years initiating EFV-based ART. Among CLHIV <3 years, higher VL at ART initiation was associated with lower mean LAZ (ß: -0.30, P=0.03), WAZ (ß: -0.32, P=0.01) and low-density lipoprotein (ß: -6.45, P=0.03) over time. Among CLHIV ≥3, a log 10 increase in pretreatment VL was associated with lower mean LAZ (ß: -0.29, P=0.07) trending towards significance and lower WAZ (ß: -0.32, P=0.05) as well as with more rapid increases in LAZ (ß: 0.14 per year, P=0.01) and WAZ (ß: 0.19 per year, P=0.04). Thirty percent of CLHIV were at risk for type 2 diabetes at ART initiation. CONCLUSIONS CLHIV initiating ART <3 years exhibited positive gains in growth and lipids, though high viremia at ART initiation was associated with persistently low growth and lipids, underscoring the need for early diagnosis and rapid treatment initiation. Future studies assessing the long-term cardiometabolic impact of these findings are warranted.

Genotype-Informed Versus Empiric Management Of VirEmia (GIVE MOVE): study protocol of an open-label randomised clinical trial in children and adolescents living with HIV in Lesotho and Tanzania. BMC Infect Dis 2020; 20:773. [PMID: 33076866 PMCID: PMC7574572 DOI: 10.1186/s12879-020-05491-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2020] [Accepted: 10/08/2020] [Indexed: 12/16/2022] Open
Abstract
Background Globally, the majority of people living with HIV have no or only limited access to HIV drug resistance testing to guide the selection of antiretroviral drugs. This is of particular concern for children and adolescents, who experience high rates of treatment failure. The GIVE MOVE trial assesses the clinical impact and cost-effectiveness of routinely providing genotypic resistance testing (GRT) to children and adolescents living with HIV who have an unsuppressed viral load (VL) while taking antiretroviral therapy (ART). Methods GIVE MOVE is an open-label randomised clinical trial enrolling children and adolescents (≥6 months to <19 years) living with HIV with a VL ≥400 copies/mL (c/mL) while taking first-line ART. Recruitment takes place at sites in Lesotho and Tanzania. Participants are randomised in a 1:1 allocation to a control arm receiving the standard of care (3 sessions of enhanced adherence counselling, a follow-up VL test, continuation of the same regimen upon viral resuppression or empiric selection of a new regimen upon sustained elevated viremia) and an intervention arm (GRT to inform onward treatment). The composite primary endpoint is the occurrence of any one or more of the following events during the 36 weeks of follow-up period: i) death due to any cause; ii) HIV- or ART-related hospital admission of ≥24 h duration; iii) new clinical World Health Organisation stage 4 event (excluding lymph node tuberculosis, stunting, oral or genital herpes simplex infection and oesophageal candidiasis); and iv) no documented VL <50 c/mL at 36 weeks follow-up. Secondary and exploratory endpoints assess additional health-related outcomes, and a nested study will assess the cost-effectiveness of the intervention. Enrolment of a total of 276 participants is planned, with an interim analysis scheduled after the first 138 participants have completed follow-up. Discussion This randomised clinical trial will assess if the availability of resistance testing improves clinical outcomes in children and adolescents with elevated viremia while taking ART.

Abstract
In Kenya, only half of children with a parent living with HIV have been tested for HIV. The effectiveness of family-centered index testing to identify children (0-14 years) living with HIV was examined. A retrospective record review was conducted among adult index patients newly enrolled in HIV care between May and July 2015; family testing, results, and linkage to treatment outcomes were followed through May 2016 at 60 high-volume clinics in Kenya. Chi square test compared yield (percentage of HIV tests positive) among children tested through family-centered index testing, outpatient and inpatient testing. Review of 1937 index client charts led to 3005 eligible children identified for testing. Of 2848 (94.8%) children tested through family-centered index testing, 127 (4.5%) had HIV diagnosed, 100 (78.7%) were linked to care, and 85 of those eligible (91.4%) initiated antiretroviral therapy (ART).Family testing resulted in higher yield compared to inpatient (1.8%, p < 0.001) or outpatient testing (1.6%, p < 0.001). The absolute number of children living with HIV identified was highest with outpatient testing. The relative contribution of testing approach to total children identified with HIV was outpatient testing (69%), family testing (26%), and inpatient testing (5%). The family testing approach demonstrated promise in achieving the first two "90s" (identification and ART initiation) of the 90-90-90 targets for children, with additional effort required to improve linkage from testing to treatment.

Drug resistance in HIV-infected children living in rural South Africa: Implications of an antiretroviral therapy initiated during the first year of life. J Clin Virol 2020; 129:104547. [PMID: 32693386 DOI: 10.1016/j.jcv.2020.104547] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2019] [Revised: 06/06/2020] [Accepted: 07/07/2020] [Indexed: 11/25/2022]
Abstract
INTRODUCTION Management of antiretroviral-drug resistance in HIV-infected children is a global health concern. We compared the long-term virological outcomes of two cohorts of children living in a rural setting of South Africa. The first cohort initiated treatment before one year and the second after two years of age. The aim of this study was to describe the long-term consequences of early treatment initiation in terms of viral load and drug-resistance. METHODS This retrospective study was conducted at the Edendale Hospital located in a peri-urban area of KwaZulu-Natal. Children were included during their planned appointment. Drug resistance was assessed genotypically on proviral DNA. RESULTS From the 161 children included in this study, 93 samples were successfully genotyped. Both cohorts had comparable viral loads, but children treated early more often presented NRTI or NNRTI mutations, while there was no difference for PI mutations rates. CONCLUSIONS Treatment was highly effective when comparing virological outcomes in both early- and late-treated cohorts. The persistence of NNRTI mutations could lead to treatment failures in children older than 3 years initiating their therapy with a NNRTI, or for those switching from a PI to NNRTI based regimen. The accumulation of NRTI mutations may lead to a functional PI monotherapy and consequently to viral escape. To promote access to HIV genotyping in resource-limited settings is challenging but essential to avoid inappropriate therapy switches in case of virological failure, and to adapt national treatment guidelines in line with the epidemiology of resistance.

Abstract
Background Early infant diagnosis (EID) of human immunodeficiency virus (HIV) and early initiation of antiretroviral therapy (ART) in HIV-infected infants can reduce the risk of mortality and improve clinical outcomes. Infant testing guidelines in KwaZulu-Natal, South Africa, changed from targeted birth EID (T-EID) only in high-risk infants to a routine birth EID (R-EID) testing strategy in 2015. Objectives To describe the impact of the implementation of R-EID on the infant treatment cascade. Method A retrospective analysis of a facility-based clinical database for the eThekwini district and the National Health Laboratory Services (NHLS) was conducted. All data on neonates (< 4 weeks of age) diagnosed with HIV between January 2013 and December 2017 (T-EID [2013-2015] and R-EID [2016-2017]) were extracted including follow-up until 1 year post-diagnosis. Results A total of 503 neonates were diagnosed HIV-infected, with 468 (93.0%) initiated on ART within a median of 6 days. There was a significant increase in the estimated percentage of HIV-infected neonates diagnosed (21% vs. 86%, p < 0.001) and initiated on ART (90% vs. 94.3%, p < 0.001) between the T-EID and R-EID periods. Despite achieving over 90% of HIV-infected neonates diagnosed and initiated on ART in 2017, retention in care and viral suppression remained low. Conclusion Implementation of R-EID in eThekwini district improved diagnosis and initiation of ART in HIV-infected neonates and should be recommended as part of diagnostic guidelines. These gains are, however, lost because of poor retention in care and viral suppression rates and therefore required urgent attention.

Abstract
Paediatric antiretroviral programmes have been implemented globally for more than a decade, yet information on long-term treatment outcomes in perinatally HIV-infected adolescents is limited. Published literature on long-term treatment outcomes was reviewed, including virologic, immunologic and growth outcomes, as well as drug resistance and factors associated with drug resistance. Outcomes were compared between high-income countries and low- and middle-income countries (LMIC), with additional focus on South Africa, the country with the biggest HIV epidemic in the world and the largest treatment programme. Treatment outcomes varied but viral suppression results globally were generally concerning. No studies from LMIC have reported on outcomes after >10 years follow-up, demonstrating that further studies are needed.

Abstract
Introduction The objective of this study was to determine the growth patterns, rates of malnutrition, and factors associated with malnutrition in children born to HIV-infected mothers in western Kenya using data from an electronic medical record system. Methods This study was a retrospective chart review of HIV-infected (HIV+) and–exposed (HEU) children (<5 years) using data collected prospectively in the course of routine clinical care and stored in the electronic medical record system in western Kenya between January 2011 and August 2016. Demographics and anthropometrics were described, with Chi-square testing to compare proportions. Multiple variable logistic regression analysis was used to identify correlates of children being stunted, underweight, and wasted. We also examined growth curves, using a resampling method to compare the areas under the fitted growth curves to compare males/females and HIV+/HEU. Results Data from 15,428 children were analyzed. The children were 51.6% (n = 7,955) female, 5.2% (n = 809) orphans, 83.3% (n = 12,851) were HEU, and 16.7% (n = 2,577) were HIV+. For HIV+ children assessed at 24 months, 50.9% (n = 217) were stunted, 26.5% (n = 145) were underweight, and 13.6% (n = 58) were wasted, while 45.0% (n = 577) of HEU children were stunted, 14.8% (n = 255) were underweight, and 5.1% (n = 65) were wasted. When comparing mean z-scores, HIV+ children tended to have larger and earlier dips in z-scores compared to HIV-exposed children, with significant differences found between the two groups (p<0.001). Factors associated with an increased risk of malnutrition included being male, HIV+, and attending an urban clinic. Maternal antiretroviral treatment during pregnancy and mixed feeding at 3 months of age decreased the risk of malnutrition. Conclusions HIV+ and HEU children differ in their anthropometrics, with HIV+ children having overall lower z-scores. Continued efforts to develop and implement sustainable and effective interventions for malnutrition are needed for children born to HIV+ mothers.

Abstract
OBJECTIVE To evaluate the nutritional, clinical and immunological status of children at HIV diagnosis in the continental region of Equatorial Guinea. METHODS Children <18 years diagnosed with HIV between 2009 and 2017 were included. Clinical, immunological and nutritional data were collected. Weight-for-height, weight-for-age and height-for-age Z-scores were calculated using WHO Child Growth Standards. The population was assessed in two equal periods (2009-2013 and 2014-2017) from the time of diagnosis. RESULTS A total of 213 children were diagnosed with HIV (49.3% males), median age 3.8 years (IQR: 1.5-8.2). A total of 121 cases (56.8%) were at WHO clinical stage III, and 53 (24.9%) were at WHO clinical stage IV. CDC immunological stage II was diagnosed in 51/130 (39.2%) and CDC stage III in 44/130 (33.8%). About 56.2% of children were underweight (weight-for-age <-2 SD); 20.1% moderately and 36.1% severely so. About 27.6% of children were wasted (weight-for-height <-2 SD); 11.9% moderately and 15.7% severely so. About 56.3% of children were stunted (height-for-age <-2 SD); 20.7% moderately and 35.6% severely so. The prevalence of wasting was higher in children ≤5 years than in children >5 years (36.4% vs. 19.1%, P = 0.026). In the second period, the prevalence of moderate-severe immunodeficiency decreased (87.2% to 67.0%, P = 0.018), without significant differences in the other nutritional or clinical data. Severe underweight was a risk factor for moderate-severe immunodeficiency (aOR: 4 [95% CI: 1.4-11.4], P = 0.010). CONCLUSIONS We highlight a high proportion of malnutrition at the time of HIV diagnosis in Guinea´s paediatric population. Early diagnosis of HIV infection is a priority, achievable by training Guinea´s physicians to suspect HIV early, introducing HIV molecular diagnostic techniques and ensuring intensive nutritional treatment.

Abstract
Background: In 2012, Rwanda introduced a Treat All approach for HIV-infected children younger than 5 years. We compared antiretroviral therapy (ART) initiation, outcomes, and retention, before and after this change. Methods: We conducted a retrospective study of children enrolled into care between June 2009 and December 2011 [Before Treat All (BTA) cohort] and between July 2012 and April 2015 [Treat All (TA) cohort]. Setting: Medical records of a nationally representative sample were abstracted for all eligible aged 18–60 months from 100 Rwandan public health facilities. Results: We abstracted 374 medical records: 227 in the BTA and 147 in the TA cohorts. Mean (SD) age at enrollment was [3 years (1.1)]. Among BTA, 59% initiated ART within 1 year, vs. 89% in the TA cohort. Median time to ART initiation was 68 days (interquartile range 14–494) for BTA and 9 days (interquartile range 0–28) for TA (P < 0.0001), with 9 (5%) undergoing same-day initiation in BTA compared with 50 (37%) in TA (P < 0.0001). Before ART initiation, 59% in the BTA reported at least one health condition compared with 35% in the TA cohort (P < 0.0001). Although overall loss to follow-up was similar between cohorts (BTA: 13%, TA: 8%, P = 0.18), loss to follow-up before ART was significantly higher in the BTA (8%) compared with the TA cohort (2%) (P = 0.02). Conclusions: Nearly 90% of Rwandan children started on ART within 1 year of enrollment, most within 1 month, with greater than 90% retention after implementation of TA. TA was also associated with fewer morbidities.

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.

Abstract
Background Long-term growth in HIV-infected infants treated early in resource-limited settings is poorly documented. Incidence of growth retardation, instantaneous risk of death related to malnutrition and growth parameters evolution during the first five years of life of uninfected and early treated HIV-infected children were compared and associated factors with growth retardation were identified. Methods Weight-for-age (WAZ), weight-for-length (WLZ), and length-for-age (LAZ) Z-scores were calculated. The ANRS-PEDIACAM cohort includes four groups of infants with three enrolled during the first week of life: HIV-infected (HI, n = 69), HIV-exposed uninfected (HEU, n = 205) and HIV-unexposed uninfected (HUU, n = 196). The last group included HIV-infected infants diagnosed before 7 months of age (HIL, n = 141). The multi-state Markov model was used to describe the incidence of growth retardation and identified associated factors. Results During the first 5 years, 27.5% of children experienced underweight (WAZ<-2), 60.4% stunting (LAZ<-2) and 41.1% wasting (WLZ<-2) at least once. The instantaneous risk of death observed from underweight state (35.3 [14.1–88.2], 84.0 [25.5–276.3], and 6.0 [1.5–24.1] per 1000 person-months for 0–6 months, 6–12 months, and 12–60 months respectively) was higher than from non-underweight state (9.6 [5.7–16.1], 20.1 [10.3–39.4] and 0.3 [0.1–0.9] per 1000 person-months). Compared to HEU, HIL and HI children were most at risk of wasting (adjusted HR (aHR) = 4.3 (95%CI: 1.9–9.8), P<0.001 and aHR = 3.3 (95%CI: 1.4–7.9), P = 0.01 respectively) and stunting for HIL (aHR = 8.4 (95%CI: 2.4–29.7). The risk of underweight was higher in HEU compared to HUU children (aHR = 5.0 (CI: 1.4–10.0), P = 0.001). Others associated factors to growth retardation were chronic pathologies, small size at birth, diarrhea and CD4< 25%. Conclusions HIV-infected children remained at high risk of wasting and stunting within the first 5 years period of follow-up. There is a need of identifying suitable nutritional support and best ways to integrate it with cART in pediatric HIV infection global care.

Abstract
Little is known about how growing up with HIV impacts educational outcomes in sub-Saharan African children. We evaluated if South African children living with HIV (CLWH) were in the appropriate school grade-for-age compared to uninfected control children. We observed higher rates of not being in the correct grade-for-age in CLWH compared with controls (OR 3.32, 95% CI: 2.07-5.34), adjusted for study site, sex, whether the child's biological father was alive, and caregiver education. Initiation of ART before 6 months of age reduced but did not eliminate this association. Whether these associations are due to biological factors or other social and environmental determinants, and how best to support CLWH to achieve educational goals, warrants further investigation.

Abstract
OBJECTIVE To describe growth evolution and its correlates in the first 5 years of antiretroviral therapy (ART) initiation among HIV-infected children followed up in West Africa. METHODS All HIV-infected children younger than 10 years followed in the IeDEA pWADA cohort while initiating ART, with at least one anthropometric measurement within the first 5 years of treatment were included in the study. Growth was described according to the WHO child growth standards, using Weight-for-age Z-score (WAZ), Height-for-age Z-score (HAZ) and Weight-for-Height/BMI-for-age Z-score (WHZ/BAZ). Growth evolution and its correlates, measured at ART initiation, were modelled in individual linear mixed models for each anthropometric indicator, with a spline term added at the 12-, 24- and 9-month time point for WAZ, HAZ and WHZ/BAZ, respectively. RESULTS Among the 4156 children selected (45% girls, median age at ART initiation 3.9 years [IQR interquartile range 1.9-6.6], and overall 68% malnourished at ART initiation), important gains were observed in the first 12, 24 and 9 months on ART for WAZ, HAZ and WHZ/BAZ, respectively. Correlates at ART initiation of a better growth evolution overtime were early age (<2 years of age), severe immunodeficiency for age, and severity of malnutrition. CONCLUSIONS Growth evolution is particularly strong within the first 2 years on ART but slows down after this period. Weight and height gains help to recover from pre-ART growth deficiency but are insufficient for the most severely malnourished. The first year on ART could be the best period for nutritional interventions to optimize growth among HIV-infected children in the long-term.

Abstract
OBJECTIVE Weight and height growth impairment is one of the most frequent manifestations in HIV-infected children and may be the first sign of disease, being considered a marker of disease progression and an independent risk factor for death. The aim of this review is to evaluate the influence of antiretroviral therapy on the growth pattern of children and adolescents living with HIV/AIDS. SOURCE OF DATA A non-systematic review was carried out in the PubMed database, with the terms "HIV", "Weight and height growth", "ART" and "children". The most relevant publications were selected. DATA SYNTHESIS Antiretroviral therapy has significantly reduced morbidity and mortality in HIV-infected children and is clearly associated with recovery of weight and height-for-age Z-scores, especially when started early, in the asymptomatic child still without weight-height impairment. Therapeutic strategies involving the GH/IGF-1 axis, especially for children with growth impairment, are still being studied. CONCLUSIONS HIV-infected children show early weight-height impairment; antiretroviral therapy improves the anthropometric profile of these children.

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.

Abstract
BACKGROUND Access to routine virologic monitoring, critical to ensuring treatment success, remains limited in low- and middle-income countries. We report on implementation of routine viral load (VL) monitoring and risk factors for virologic failure among HIV-infected children on antiretroviral treatment (ART) in Western Kenya. METHODS Routine VL testing was introduced in western Kenya in November 2013. We performed a case-control study among 1190 HIV-infected children ≤15 years on ART who underwent routine VL testing June 2014-May 2015. A random sample of 98 cases (virologic failure define as VL >1000 cps/mL) and 201 controls (VL <1000 cps/mL) from five facilities in three high HIV prevalence counties in Kenya were followed for a minimum of 12 months. Data from patient charts were analyzed using logistic regression to determine factors associated with failure to attain virologic suppression at initial routine and subsequent VL testing among cases. RESULTS Overall, 1190 (94%) children with a median age of 8 years underwent routine VL testing of whom (37%) had virological failure. Among the 299 cases and controls, WHO stage, baseline CD4 count and time since ART initiation were not associated with virologic failure during the follow-up period. In multivariable analysis, unsuppressed children at initial test were more likely to be male (adjusted Odds Ratio (aOR) 2.1, 95% Confidence Interval (CI) 2.1-3.6) and have had an ART regimen change (aOR 2.0, CI 1.0-3.7) than controls. Of the two-thirds of children 201/299 who had a subsequent VL performed, VL suppression was greater among those suppressed at initial test 126/135 (93.3%) compared to children with virologic failure 15/66 (22.7%, p<0.0001). Among those failing at first test who achieved viral suppression in follow up, 12/15 (80%) were on a protease inhibitor (PI)-based regimen. In the multivariable analysis of children with subsequent VL testing, children on PI-based 2nd line regimens were 10-fold more likely to achieve viral suppression than children on first-line NNRTI-based ART (adjusted Odds Ratio [aOR] 0.1; 95%CI 0.0-0.4). CONCLUSION Coverage of initial routine viral load testing among children on ART in western Kenya is high. However, subsequent testing and virologic suppression are low in children with virologic failure on initial routine viral load test. There is an urgent need to improve management and viral load monitoring of children living with HIV experiencing treatment failure to ensure improved long-term outcomes.

Abstract
BACKGROUND There is limited information about malnutrition, growth evolution and metabolic changes among children initiated early on lopinavir-based antiretroviral therapy (ART) in Africa. METHODS HIV-1-infected children, age <2 years were initiated on ART, as part of the MONOD ANRS 12206 project, conducted in Burkina Faso and Côte d'Ivoire. Weight-for-age, height-for-age and weight-for-height Z scores defined malnutrition [Z score less than -2 standard deviations (SDs)] using World Health Organization growth references. Biologic data were collected every 6 months. Factors associated with baseline malnutrition were evaluated using multivariate logistic regression, and with growth evolution in the first 24 months on ART using linear mixed models. RESULTS Between 2011 and 2013, 161 children were enrolled: 64% were from Abidjan, 54% were girls. At ART initiation, median age was 13.7 months (interquartile range 7.7; 18.4), 52% were underweight (weight-for-age), 52% were stunted (height-for-age) and 36% were wasted (weight-for-height). Overall, baseline malnutrition was more likely for children living in Burkina Faso, with low birth weight, never breastfed and older age (12-24 months). Growth improved on ART, mainly within the first 6 months for weight, and was greater for the most severely malnourished children at baseline, but 8%-32% remained malnourished after 24 months. Over the 24-month period of ART, there was a significant increase of hypercholesterolemia and decrease of anemia and hypoalbuminemia. CONCLUSIONS Prevalence of malnutrition was high before ART initiation. Even though growth improved on ART, some children remained malnourished even after 2 years of ART, highlighting the need for more active nutritional support.

Abstract
BACKGROUND We assessed a nutritional support intervention in malnourished HIV-infected children in a HIV-care program of the University Hospital Gabriel Touré, Bamako, Mali. METHODS All HIV-infected children younger than 15 years were diagnosed for malnutrition between 07 and 12, 2014. Malnutrition was defined according to the WHO growth standards with Z-scores. Two types were studied: acute malnutrition (AM) and chronic malnutrition (CM). All participants were enrolled in a 6-month prospective interventional cohort, receiving Ready-To-Use Therapeutic Food, according to type of malnutrition. The nutritional intervention was offered until child growth reached -1.5 SD threshold. Six-month probability to catch up growth (>-2 SD) was assessed for AM using Kaplan-Meier curves and Cox model. RESULTS Among the 348 children screened, 198 (57%) were malnourished of whom 158 (80%) children were included: 97 (61%) for AM (35 with associated CM) and 61 (39%) with CM. Fifty-nine percent were boys, 97% were on antiretroviral therapy, median age was 9.5 years (Interquartile Range: 6.7-12.3). Among children with AM, 74% catch-up their growth at 6-month; probability to catch-up growth was greater for those without associated CM (adjusted Hazard Ratio = 1.97, CI 95%: 1.13 to 3.44). Anemia decreased significantly from 40% to 12% at the end of intervention (P < 0.001). CONCLUSIONS This macronutrient intervention showed 6-month benefits for weight gain and reduced anemia among these children mainly on antiretroviral therapy for years and aged greater than 5 years at inclusion. Associated CM slows down AM recovery and needs longer support. Integration of nutritional screening and care in the pediatric HIV-care package is needed to optimize growth and prevent metabolic disorders.

Abstract
BACKGROUND Based on clinical trial results, the World Health Organization recommends infant HIV testing at age 4-6 weeks and immediate antiretroviral therapy (ART) initiation in all HIV-infected infants. Little is known about the outcomes of HIV-infected infants diagnosed with HIV in the first weeks of life in resource-limited settings. We assessed ART initiation and mortality in the first year of life among infants diagnosed with HIV by 12 weeks of age. METHODS Cohort of HIV-infected infants in Kinshasa and Blantyre diagnosed before 12 weeks to estimate 12-month cumulative incidences of ART initiation and mortality, accounting for competing risks. Multivariate models were used to estimate associations between infant characteristics and timing of ART initiation. RESULTS One hundred and twenty-one infants were diagnosed at a median age of 7 weeks (interquartile range, 6-8). The cumulative incidence of ART initiation was 46% [95% confidence interval (CI), 36%, 55%] at 6 months and 70% (95% CI 60%, 78%) at 12 months. Only age at HIV diagnosis was associated with ART initiation by age 6 months, with a subdistribution hazard ratio of 0.70 (95% CI 0.52, 0.91) for each week increase in age at DNA polymerase chain reaction test. The 12-month cumulative incidence of mortality was 20% (95% CI 13%, 28%). CONCLUSIONS Despite early diagnosis of HIV, ART initiation was slow and mortality remained high, underscoring the complexity in translating clinical trial findings and World Health Organization's guidance into real-life practice. Novel and creative health system interventions will be required to ensure that all HIV-infected infants achieve optimal treatment outcomes under routine care settings.

Abstract
BACKGROUND Early antiretroviral therapy (ART) initiation in HIV-infected infants significantly improves survival but is often delayed in resource-limited settings. Adding HIV testing of infants at birth to the current recommendation of testing at age 4-6 weeks may improve testing rates and decrease time to ART initiation. We modeled the benefit of adding HIV testing at birth to the current 6-week testing algorithm. METHODS Microsoft Excel was used to create a decision-tree model of the care continuum for the estimated 1,400,000 HIV-infected women and their infants in sub-Saharan Africa in 2012. The model assumed average published rates for facility births (42.9%), prevention of mother-to-child HIV transmission utilization (63%), mother-to-child-transmission rates based on prevention of mother-to-child HIV transmission regimen (5%-40%), return of test results (41%), enrollment in HIV care (52%), and ART initiation (54%). We conducted sensitivity analyses to model the impact of key variables and applied the model to specific country examples. RESULTS Adding HIV testing at birth would increase the number of infants on ART by 204% by age 18 months. The greatest increase is seen in early ART initiations (543% by age 3 months). The increase would lead to a corresponding increase in survival at 12 months of age, with 5108 fewer infant deaths (44,550, versus 49,658). CONCLUSION Adding HIV testing at birth has the potential to improve the number and timing of ART initiation of HIV-infected infants, leading to a decrease in infant mortality. Using this model, countries should investigate a combination of HIV testing at birth and during the early infant period.

Abstract
OBJECTIVE The report of the 'Mississippi baby' who was initiated on antiretroviral therapy (ART) within 30 h of birth and maintained viral suppression off ART for 27 months has increased interest in the timing of ART initiation early in life. We examined associations between age at ART initiation and virologic outcomes in five cohorts of HIV-infected infants and young children who initiated ART before 2 years of age in Johannesburg, South Africa. METHODS We compared those who initiated ART early (<6 months of age) and those who started ART late (6-24 months of age). Two primary outcomes were examined: initial response to ART in three cohorts and later sustained virologic control after achieving suppression on ART in two cohorts. RESULTS We did not observe consistent differences in initial viral suppression rates by age at ART initiation. Overall, initial viral suppression rates were low. Only 31, 40.1, and 26.5% of early-treated infants (<6 months of age) in the three cohorts, respectively, were suppressed less than 50 copies/ml of HIV RNA 6 months after starting ART. We did observe better sustained virologic control after achieving suppression on ART among infants starting ART early compared with late. Children who started ART early were less likely to experience viral rebound (>50 copies/ml or >1000 copies/ml) than children who started late in both cohorts. CONCLUSION These findings provide additional support for early initiation of ART in HIV-infected infants.

Danaei G, Andrews KG, Sudfeld CR, Fink G, McCoy DC, Peet E, Sania A, Smith Fawzi MC, Ezzati M, Fawzi WW. Risk Factors for Childhood Stunting in 137 Developing Countries: A Comparative Risk Assessment Analysis at Global, Regional, and Country Levels. PLoS Med 2016; 13:e1002164. [PMID: 27802277 PMCID: PMC5089547 DOI: 10.1371/journal.pmed.1002164] [Citation(s) in RCA: 200] [Impact Index Per Article: 25.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2015] [Accepted: 09/23/2016] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND Stunting affects one-third of children under 5 y old in developing countries, and 14% of childhood deaths are attributable to it. A large number of risk factors for stunting have been identified in epidemiological studies. However, the relative contribution of these risk factors to stunting has not been examined across countries. We estimated the number of stunting cases among children aged 24-35 mo (i.e., at the end of the 1,000 days' period of vulnerability) that are attributable to 18 risk factors in 137 developing countries. METHODS AND FINDINGS We classified risk factors into five clusters: maternal nutrition and infection, teenage motherhood and short birth intervals, fetal growth restriction (FGR) and preterm birth, child nutrition and infection, and environmental factors. We combined published estimates and individual-level data from population-based surveys to derive risk factor prevalence in each country in 2010 and identified the most recent meta-analysis or conducted de novo reviews to derive effect sizes. We estimated the prevalence of stunting and the number of stunting cases that were attributable to each risk factor and cluster of risk factors by country and region. The leading risk worldwide was FGR, defined as being term and small for gestational age, and 10.8 million cases (95% CI 9.1 million-12.6 million) of stunting (out of 44.1 million) were attributable to it, followed by unimproved sanitation, with 7.2 million (95% CI 6.3 million-8.2 million), and diarrhea with 5.8 million (95% CI 2.4 million-9.2 million). FGR and preterm birth was the leading risk factor cluster in all regions. Environmental risks had the second largest estimated impact on stunting globally and in the South Asia, sub-Saharan Africa, and East Asia and Pacific regions, whereas child nutrition and infection was the second leading cluster of risk factors in other regions. Although extensive, our analysis is limited to risk factors for which effect sizes and country-level exposure data were available. The global nature of the study required approximations (e.g., using exposures estimated among women of reproductive age as a proxy for maternal exposures, or estimating the impact of risk factors on stunting through a mediator rather than directly on stunting). Finally, as is standard in global risk factor analyses, we used the effect size of risk factors on stunting from meta-analyses of epidemiological studies and assumed that proportional effects were fairly similar across countries. CONCLUSIONS FGR and unimproved sanitation are the leading risk factors for stunting in developing countries. Reducing the burden of stunting requires a paradigm shift from interventions focusing solely on children and infants to those that reach mothers and families and improve their living environment and nutrition.

Abstract
OBJECTIVES To describe the head growth of children according to maternal and child HIV infection status. DESIGN Longitudinal analysis of head circumference data from 13 647 children followed from birth in the ZVITAMBO trial, undertaken in Harare, Zimbabwe, between 1997 and 2001, prior to availability of antiretroviral therapy (ART) or cotrimoxazole prophylaxis. METHODS Head circumference was measured at birth, then at regular intervals through 24 months of age. Mean head circumference-for-age Z-scores (HCZ) and prevalence of microcephaly (HCZ < -2) were compared between HIV-unexposed children, HIV-exposed uninfected (HEU) children and children infected with HIV in utero (IU), intrapartum (IP) and postnatally (PN). RESULTS Children infected with HIV in utero had head growth restriction at birth. Head circumference Z-scores remained low throughout follow-up in IP children, whereas they progressively declined in IU children. During the second year of life, HCZ in the PN group declined, reaching a similar mean as IP-infected children by 21 months of age. Microcephaly was more common among IU and IP children than HIV-uninfected children through 24 months. HEU children had significantly lower head circumferences than HIV-unexposed children through 12 months. CONCLUSION HIV-infected children had lower head circumferences and more microcephaly than HIV-uninfected children. Timing of HIV acquisition; influenced HCZ, with those infected before birth having particularly poor head growth. HEU children had poorer head growth until 12 months of age. Correlations between head growth and neurodevelopment in the context of maternal/infant HIV infection, and further studies from the current ART era, will help determine the predictive value of routine head circumference measurement.

Abstract
OBJECTIVES To describe growth in HIV-infected children on long-term antiretroviral therapy (ART) and to assess social, clinical, immunological and virological factors associated with suboptimal growth. METHODS This observational cohort study included all HIV-infected children at an urban ART site in South Africa who were younger than 5 years at ART initiation and with more than 5 years of follow-up. Growth was assessed using weight-for-age Z-scores (WAZ), height-for-age Z-scores (HAZ) and body mass index (BMI)-for-age Z-scores (BAZ). Children were stratified according to pre-treatment anthropometry and age. Univariate and mixed linear analysis were used to determine associations between independent variables and weight and height outcomes. RESULTS The majority of the 159 children presented with advanced clinical disease (90%) and immunosuppression (89%). Before treatment underweight, stunting and wasting were common (WAZ<-2 = 50%, HAZ<-2 = 73%, BAZ<-2 = 19%). Weight and BMI improved during the initial 12 months, while height improved over the entire 5-year period. Height at study exit was significantly worse for children with growth impairment at ART initiation (P < 0.001), and infants (<1 year) demonstrated superior improvement in terms of BMI (P = 0.04). Tuberculosis was an independent risk factor for suboptimal weight (P = 0.01) and height (P = 0.02) improvement. Weight gain was also hindered by lack of electricity (P = 0.04). Immune reconstitution and virological suppression were not associated with being underweight or stunted at study endpoint. CONCLUSIONS Malnutrition was a major clinical concern for this cohort of HIV-infected children. Early ART initiation, tuberculosis co-infection management and nutritional interventions are crucial to ensure optimal growth in HIV-infected children.

Abstract
Objective To describe long-term treatment outcomes of a pediatric HIV cohort in Mozambique. Design Retrospective analysis of routine monitoring data. Setting Secondary health care facilities in the Chamanculo Health District of Maputo. Subjects A total of 1,335 antiretroviral treatment (ART) naïve children <15 years of age enrolled in HIV care between 2002 and 2010. Intervention HIV care, ART (since 2003), task shifting to lower cadre nurses, counseling by lay counselors, active patient tracing, nutritional support, support by a psychologist, targeted viral load testing, and switch to second-line treatment. Main outcome measures Kaplan–Meier estimates for retention in care (RIC), CD4 cell percentage, body mass index for age z-score, and adjusted incidence rate ratios for attrition (death or loss to follow-up) as calculated by Poisson regression. Results The RIC at 6 years in the pre-ART cohort was 44% (95% confidence interval: 38–49), and the one at 8 years in the ART cohort was 70% (64–75). Risk factors for attrition included young age, low CD4 percentage, underweight, active tuberculosis, and enrollment/treatment initiation after 2006. The mean CD4 percentage increased strongly at 1 year on treatment and remained high thereafter. The body mass index for age z-score sharply increased at 1 year after treatment initiation before stabilizing at pre-ART levels thereafter. Conclusions Good clinical and immunological treatment outcomes up to 8 years of follow-up on ART can be achieved in a context of shortage of health workers and a high level of task-shifting approach.

Abstract
The South African prevention of mother to child transmission programme has made excellent progress in reducing vertical HIV transmission, and paediatric antiretroviral therapy programmes have demonstrated good outcomes with increasing treatment initiation in younger children and infants. However, both in South Africa and across sub-Saharan African, lack of boosted peri-partum prophylaxis for high-risk vertical transmission, loss to follow-up, and failure to initiate HIV-infected infants on antiretroviral therapy (ART) before disease progression are key remaining gaps in neonatal HIV-related care. In this issue of the Southern African Journal of HIV Medicine, experts provide valuable recommendations for addressing these gaps. The present article highlights a number of areas where evidence is lacking to inform guidelines and programme development for optimal neonatal HIV-related care.

Abstract
More than 90% of the estimated 3.2 million children with HIV worldwide, at the end of 2013, were living in sub-Saharan Africa. The management of these children was still difficult in 2014 despite the progress in access to antiretroviral drugs. A great number of HIV-infected children are not diagnosed at 6 weeks and start antiretroviral treatment late, at an advanced stage of HIV disease complicated by other comorbidities such as malnutrition. Malnutrition is a major problem in the sub-Saharan Africa global population; it is an additional burden for HIV-infected children because they do not respond as well as non-infected children to the usual nutritional care. HIV infection and malnutrition interact, creating a vicious circle. It is important to understand the relationship between these 2 conditions and the effect of antiretroviral treatment on this circle to taking them into account for an optimal management of pediatric HIV. An improved monitoring of growth during follow-up and the introduction of a nutritional support among HIV-infected children, especially at antiretroviral treatment initiation, are important factors that could improve response to antiretroviral treatment and optimize the management of pediatric HIV in resource-limited countries.

Abstract
BACKGROUND Quantifying pediatric immunologic recovery by highly active antiretroviral therapy (HAART) initiation at different CD4 percentage (CD4%) and age thresholds may inform decisions about timing of treatment initiation. METHODS HIV-1-infected, HAART-naive children in Europe and the Americas were followed from 2002 through 2009 in PENPACT-1. Data from 162 vertically infected children, with at least World Health Organization "mild" immunosuppression and CD4% <10th percentile, were analyzed for improvement to a normal CD4% (≥10th percentile) within 4 years after HAART initiation. Data from 209 vertically infected children, regardless of immune status, were analyzed for CD4% outcomes at 4 years and viral failure within 4 years. RESULTS Seventy-two percent of baseline immunosuppressed children recovered to normal within 4 years. Compared with "severe" immunosuppression, more children with "mild" immunosuppression (difference 36%, 95% confidence interval [CI]: 22% to 49%) or "advanced" immunosuppression (difference 20.8%, 95% CI: 5.8% to 35.9%) recovered a normal CD4%. For each 5-year increase in baseline age, the proportion of children achieving a normal CD4% declined by 19% (95% CI: 11% to 27%). Combining baseline CD4% and age effects resulted in >90% recovery when initiating HAART with "mild" immunosuppression at any age or "advanced" immunosuppression at age <3 years. Baseline CD4% effects became greater with increasing age (P = .02). At 4 years, most immunologic benefits were still significant but diminished. Viral failure was highest in infancy (56%) and adolescence (63%). CONCLUSIONS Initiating HAART at higher CD4% and younger ages maximizes potential for immunologic recovery. Guidelines should weigh immunologic benefits against long-term risks.

Abstract
Endocrine changes (including adrenal insufficiency, disorders of growth and puberty, thyroid dysfunction, metabolic abnormalities and osteopenia) accompany human immunodeficiency virus (HIV) infection in pediatric patients. The cause of these changes is multifactorial and includes direct viral effects of HIV, and effects of antiretroviral therapy. These effects may be of particular importance in childhood given the critical developmental processes that occur during this time period and the likelihood of prolonged exposure to the virus and medications.

Abstract
BACKGROUND Initiation criteria and pediatric antiretroviral treatment regimens have changed over the past few years in South Africa. We reported worse early virological outcomes associated with the use of abacavir (ABC)-based regimens at 1 large site: here, we expand this analysis to multiple sites in the IeDEA-Southern Africa collaboration. METHODS Data for 9543 antiretroviral treatment-naïve children <16 years at treatment initiation started on either stavudine/lamivudine (d4T/3TC) or ABC/3TC with efavirenz (EFV) or ritonavir-boosted lopinavir (LPV/r) treated at 6 clinics in Johannesburg and Cape Town, South Africa, were analyzed with χ tests and logistic regression to evaluate viral suppression at 6 and 12 months. RESULTS Prevalence of viral suppression at 6 months in 2174 children started on a d4T-based LPV/r regimen was greater (70%) than among 438 children started on an ABC-based LPV/r regimen (54%, P < 0.0001). Among 3189 children started on a d4T-based EFV regimen, a higher proportion (86%) achieved suppression at 6 months compared with 391 children started on ABC-containing EFV regimens (78%, P < 0.0001). Relative benefit of d4T versus ABC on 6-month suppression remained in multivariate analysis after adjustment for pretreatment characteristics, cohort and year of program [LPV/r: odds ratio = 0.57 (confidence interval: 0.46-0.72); EFV: odds ratio = 0.46 (confidence interval: 0.32-0.65)]. CONCLUSIONS This expanded analysis is consistent with our previous report of worse virological outcomes after ABC was introduced as part of first-line antiretroviral treatment in South Africa. Whether due to the drug itself or coincident with other changes over time, continued monitoring and analyses must clarify causes and prevent suboptimal long-term outcomes.

Sex differences in responses to antiretroviral treatment in South African HIV-infected children on ritonavir-boosted lopinavir- and nevirapine-based treatment. BMC Pediatr 2014; 14:39.

Abstract
BACKGROUND While studies of HIV-infected adults on antiretroviral treatment (ART) report no sex differences in immune recovery and virologic response but more ART-associated complications in women, sex differences in disease progression and response to ART among children have not been well assessed. The objective of this study was to evaluate for sex differences in response to ART in South African HIV-infected children who were randomized to continue ritonavir-boosted lopinavir (LPV/r)-based ART or switch to nevirapine-based ART. METHODS ART outcomes in HIV-infected boys and girls in Johannesburg, South Africa from 2005-2010 were compared. Children initiated ritonavir-boosted lopinavir (LPV/r)-based ART before 24 months of age and were randomized to remain on LPV/r or switch to nevirapine-based ART after achieving viral suppression. Children were followed for 76 weeks post-randomization and then long-term follow up continued for a minimum of 99 weeks and maximum of 245 weeks after randomization. Viral load, CD4 count, lipids, anthropometrics, drug concentrations, and adherence were measured at regular intervals. Outcomes were compared between sexes within treatment strata. RESULTS A total of 323 children (median age 8.8 months, IQR 5.1-13.5), including 168 boys and 155 girls, initiated LPV/r-based ART and 195 children were randomized. No sex differences in risk of virological failure (confirmed viral load >1000 copies/mL) by 156 weeks post-randomization were observed within either treatment group. Girls switched to nevirapine had more robust CD4 count improvement relative to boys in this group through 112 weeks post-randomization. In addition, girls remaining on LPV/r had higher plasma concentrations of ritonavir than boys during post-randomization visits. After a mean of 3.4 years post-randomization, girls remaining on LPV/r also had a higher total cholesterol:HDL ratio and lower mean HDL than boys on LPV/r. CONCLUSIONS Sex differences are noted in treated HIV-infected children even at a young age, and appear to depend on treatment regimen. Future studies are warranted to determine biological mechanisms and clinical significance of these differences. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT00117728.

Abstract
The recent case report of an HIV-infected child in Mississippi with viral control post-antiretroviral therapy (ART) interruption has sparked interest in the possibility of 'functional cure' in infants if they initiate ART very soon after birth. The 'Mississippi baby' also raises many new questions around the clinical care of HIV-infected infants and young children, including when treatment should be initiated, why treatment should be initiated, what treatment should be initiated, and how to identify infants early enough to treat them adequately. Here, we review research conducted before the report of the 'Mississippi baby' highlighting the important new issues that now need to be taken into consideration.

Abstract
Most infants born to human immunodeficiency virus (HIV)-infected women escape HIV infection. Infants evade infection despite an immature immune system and, in the case of breastfeeding, prolonged repetitive exposure. If infants become infected, the course of their infection and response to treatment differs dramatically depending upon the timing (in utero, intrapartum, or during breastfeeding) and potentially the route of their infection. Perinatally acquired HIV infection occurs during a critical window of immune development. HIV's perturbation of this dynamic process may account for the striking age-dependent differences in HIV disease progression. HIV infection also profoundly disrupts the maternal immune system upon which infants rely for protection and immune instruction. Therefore, it is not surprising that infants who escape HIV infection still suffer adverse effects. In this review, we highlight the unique aspects of pediatric HIV transmission and pathogenesis with a focus on mechanisms by which HIV infection during immune ontogeny may allow discovery of key elements for protection and control from HIV.

Virologic, immunologic and clinical response of infants to antiretroviral therapy in Kampala, Uganda. BMC Pediatr 2013; 13:42. [PMID: 23536976 PMCID: PMC3616823 DOI: 10.1186/1471-2431-13-42] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2012] [Accepted: 03/22/2013] [Indexed: 11/23/2022] Open
Abstract
Background Antiretroviral therapy (ART) is known to save lives. Among HIV-infected infants living in resource constrained settings, the short and long term benefits of ART are only partially known. This study was designed to determine the virologic, immunologic and clinical outcomes of antiretroviral therapy in a cohort of HIV-infected infants receiving care from an outpatient clinic in Kampala, Uganda. Methods A prospective cohort of HIV-infected infants receiving treatment at the Baylor-Uganda clinic was analyzed. Patients were diagnosed, enrolled and followed up at the clinic. HIV viral load, CD4 cell counts and clinical progress were assessed during follow-up. Descriptive statistical analysis and logistic regression modeling to determine predictors of treatment success were conducted. Results Of 91 HIV-infected infants enrolled into the cohort, 53 (58.2%) infants were female; 43 (47.3%) were 6 months of age or younger, and 50 (55.6%) had advanced HIV/AIDS disease (Clinical stage 3 or 4). Eighty four infants started ART and 78 (92.9%) completed 6 months of treatments. Fifty six (71.8%) infants attained virologic suppression by month-6 of ART, and at month-12 of ART, the cumulative probability of attaining viral suppression was 83.1%. None of the baseline infant factors (age, sex, WHO stage, CD4 cell percent, weight for age, or height for age z-score) predicted treatment success. There was an increase in CD4 cells from a baseline mean of 23% to 30% at month-6 of treatment (p<0.001) and by month-24 of ART, the mean CD4 percent was 36%. A total of 7 patients died while on ART and another 7 experienced adverse events that were related to treatment. Conclusion Our results show that, even among very young patients from resource constrained settings, ART dramatically suppresses HIV replication, allows immune recovery and clinical improvement, and is safe. However, baseline characteristics do not predict recovery in this age group.
