Predicting mortality within 1 year of ART initiation in children and adolescents living with HIV in sub-Saharan Africa: a retrospective observational cohort study. Lancet Glob Health 2024; 12:e929-e937. [PMID: 38762295 PMCID: PMC11149103 DOI: 10.1016/s2214-109x(24)00091-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Revised: 01/26/2024] [Accepted: 02/22/2024] [Indexed: 05/20/2024]
Abstract
BACKGROUND Differentiated service delivery (DSD) for children and adolescents living with HIV can improve targeted resource use. We derived a mortality prediction score to guide clinical decision making for children and adolescents living with HIV. METHODS Data for this retrospective observational cohort study were evaluated for all children and adolescents living with HIV and initiating antiretroviral therapy (ART); aged 0-19 years; and enrolled at Baylor clinics in Eswatini, Malawi, Lesotho, Tanzania, and Uganda between 2005 and 2020. Data for clinical prediction, including anthropometric values, physical examination, ART, WHO stage, and laboratory tests were captured at ART initiation. Backward stepwise variable selection and logistic regression were performed to develop predictive models for mortality within 1 year of ART initiation. Probabilities of mortality were generated, compared with true outcomes, internally validated, and evaluated against WHO advanced HIV criteria. FINDINGS The study population included 16 958 children and adolescents living with HIV and initiated on ART between May 18, 2005, and Dec 18, 2020. Predictive variables for the most accurate model included: age, CD4 percentage, white blood cell count, haemoglobin concentration, platelet count, and BMI Z score as continuous variables, and WHO clinical stage and oedema, abnormal muscle tone and respiratory distress on examination as categorical variables. The area under the curve (AUC) of the predictive model was 0·851 (95% CI 0·839-0·863) in the training set and 0·822 (0·800-0·845) in the test set, compared with 0·606 (0·595-0·617) for the WHO advanced HIV criteria (p<0·0001). INTERPRETATION This study evaluated a large, multinational population to derive a mortality prediction tool for children and adolescents living with HIV. The model more accurately predicted clinical outcomes than the WHO advanced HIV criteria and has the potential to improve DSD for children and adolescents living with HIV in high-burden settings.

Heliyon 2024; 10:e27961. [PMID: 38596025 PMCID: PMC11002537 DOI: 10.1016/j.heliyon.2024.e27961] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2023] [Revised: 02/17/2024] [Accepted: 03/08/2024] [Indexed: 04/11/2024] Open
Abstract
Introduction Highly active antiretroviral therapy (HAART) was piloted in 2002 and was scaled up in 2003 in mainland China. The aim of this study was to evaluate the mortality and its possible predictors based on the long-term initial antiretroviral therapy (ART) cohort among HIV positive children and adolescents. Methods This prospective open-labeled multicenter cohort study was conducted from January 2008 to July 2021. The participants were recruited from six representative sites in mainland China. A total of 609 participants with an HIV-positive serostatus and <18 years old were recruited and each participant was informed consent at the time of enrollment. Mortality and annual hazard were calculated, and predictors for death were analyzed using Cox regression models generating hazard ratios (HR). Results The results showed that the mortality was 0.721 per hundred person-years, and the annual hazard was less than 0.10 over time. Both CD4+T cell count and CD4+T cell percentage declined in the death group during the follow-up. The Cox regression model showed that the baseline low CD4+T cell count level (Low vs. High: aHR = 8.309, 95% CI: (1.093, 63.135)) and age >5 years old at HIV diagnosis (6-12 vs. 0-5: aHR = 3.140, 95%CI: (1.331, 27.411)); 13-18 vs. 0-5: aHR = 5.451, 95%CI: (1.434, 20.724)) were possible risk factors for death. Conclusion The longitudinal cohort study demonstrated the efficacy of China's ART program among HIV-positive children and adolescents which could be beneficial to other countries with limited resources.

Estimating the costs of adolescent HIV care visits and an intervention to facilitate transition to adult care in Kenya. PLoS One 2024; 19:e0296734. [PMID: 38330069 PMCID: PMC10852328 DOI: 10.1371/journal.pone.0296734] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2022] [Accepted: 12/18/2023] [Indexed: 02/10/2024] Open
Abstract
INTRODUCTION Adolescents with HIV in sub-Saharan Africa face challenges transitioning to adult HIV care, which can affect long-term HIV care adherence and retention. An adolescent transition package (ATP) focused on transition tools can improve post-transition clinical outcomes, but its implementation costs are unknown. METHODS We estimated the average cost per patient of an HIV care visit and ATP provision to adolescents. Data was collected from 13 HIV clinics involved in a randomized clinical trial evaluating ATP in western Kenya. We conducted a micro-costing and activity-driven time estimation to assess costs from the provider perspective. We developed a flow-map, conducted staff interviews, and completed time and motion observation. ATP costs were estimated as the difference in average cost for an HIV care transition visit in the intervention compared to control facilities. We assessed uncertainty in costing estimates via Monte Carlo simulations. RESULTS The average cost of an adolescent HIV care visit was 29.8USD (95%CI 27.5, 33.4) in the standard of care arm and 32.9USD (95%CI 30.5, 36.8) in the ATP intervention arm, yielding an incremental cost of 3.1USD (95%CI 3.0, 3.4) for the ATP intervention. The majority of the intervention cost (2.8USD) was due ATP booklet discussion with the adolescent. CONCLUSION The ATP can be feasibly implemented in HIV care clinics at a modest increase in overall clinic visit cost. Our cost estimates can be used to inform economic evaluations or budgetary planning of adolescent HIV care interventions in Kenya.

Adherence to Antiretroviral Therapy and Associated Factors Among HIV-Infected Children in Public Health Institutions of Adwa, Axum, and Shire Towns of Tigray, Northern Ethiopia: A Cross-Sectional Study. HIV AIDS (Auckl) 2023; 15:217-224. [PMID: 37163177 PMCID: PMC10164383 DOI: 10.2147/hiv.s282938] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2020] [Accepted: 06/28/2021] [Indexed: 05/11/2023] Open
Abstract
Background Antiretroviral therapy (ART) provision was among the major challenge of treatments. Maintaining the optimal level of adherence among children living with HIV/AIDS is a pivotal step towards achieving treatment success. However, there are limited studies on child's ART adherence. Therefore, this study aimed to assess the level of adherence to antiretroviral therapy and associated factors among HIV-infected children in health institutions of Adwa, Axum, and Shire towns, Tigray, Northern Ethiopia. Methods An institutional-based cross-sectional study was conducted among human immunodeficiency virus (HIV)-infected children in between February and April, 2016. A total of 255 children who were taking antiretroviral therapy in the randomly selected three health facilities from Adwa, Axum and Shire towns were included. Data were collected using pretested and structured questionnaires using a face-to-face interview. The collected data were entered into Epi Info version 7 and then exported to SPSS version 21 for analysis. Bivariate and multivariate binary logistic regression models were used to determine the factors associated with adherence to antiretroviral therapy among HIV-infected children. Results A total of the 255 study participants were included in the study. The level of ART adherence among HIV-positive children was 212 (84.8%). Knowledge of caregivers about ART treatment (AOR = 2.78, 95% CI: 1.18, 6.53), occupational status (AOR = 4.78, 95% CI: 1.26, 18.91), appointment to ART less than two months (AOR = 3.05, 95% CI: 1.21, 7.70) and use of memory aids (AOR = 4.58, 95% CI: 1.73, 12.13) were independently associated with adherence to ART. Conclusion The level of adherence to antiretroviral therapy was low. Healthcare providers should reinforce adherence intervention and counseling sessions during follow-up and address the proper use of medication reminders to help children take their drugs appropriately.

Abstract
BACKGROUND Early antiretroviral treatment (ART) improves outcomes in children, but few studies have comprehensively evaluated the impact of ART started from the first week of life. METHODS Children diagnosed with HIV within 96 hours of life were enrolled into the Early Infant Treatment Study in Botswana and followed on ART for 96 weeks. Nevirapine, zidovudine, and lamivudine were initiated; nevirapine was switched to lopinavir/ritonavir between weeks 2-5 in accordance with gestational age. Clinical and laboratory evaluations occurred at weeks 1, 2, 4, 8, 12, 24, 36, 48, 60, 72, 84, and 96. FINDINGS Forty children initiated ART at a median of 2 (IQR 2, 3) days of life; 38 (95%) completed follow-up through 96 weeks, and 2 (5%) died between 12 and 24 weeks. ART was well tolerated; 9 children (24%) experienced a grade 3 or 4 hematologic event, and 2 (5%) required treatment modification for anemia. The median 96-week CD4 count was 1625 (IQR 1179, 2493) cells/mm 3 with only 5/38 (13%) having absolute counts <1000 cells/mm 3 . Although 23 (61%) had at least one visit with HIV-1 RNA ≥40 copies/mL at or after 24 weeks, 28 (74%) had HIV-1 RNA <40 copies/mL at the 96-week visit. Median cell-associated HIV-1 DNA at 84/96-week PBMCs was 1.9 (IQR 1.0, 2.6) log 10 copies/10 6 cells. Pre-ART reservoir size at birth was predictive of the viral reservoir at 84/96 weeks. INTERPRETATION Initiation of ART in the first week of life led to favorable clinical outcomes, preserved CD4 cell counts, and low viral reservoir through 96 weeks of life.

Machine learning outperformed logistic regression classification even with limit sample size: A model to predict pediatric HIV mortality and clinical progression to AIDS. PLoS One 2022; 17:e0276116.

Abstract
Logistic regression (LR) is the most common prediction model in medicine. In recent years, supervised machine learning (ML) methods have gained popularity. However, there are many concerns about ML utility for small sample sizes. In this study, we aim to compare the performance of 7 algorithms in the prediction of 1-year mortality and clinical progression to AIDS in a small cohort of infants living with HIV from South Africa and Mozambique. The data set (n = 100) was randomly split into 70% training and 30% validation set. Seven algorithms (LR, Random Forest (RF), Support Vector Machine (SVM), K-Nearest Neighbor (KNN), Naïve Bayes (NB), Artificial Neural Network (ANN), and Elastic Net) were compared. The variables included as predictors were the same across the models including sociodemographic, virologic, immunologic, and maternal status features. For each of the models, a parameter tuning was performed to select the best-performing hyperparameters using 5 times repeated 10-fold cross-validation. A confusion-matrix was built to assess their accuracy, sensitivity, and specificity. RF ranked as the best algorithm in terms of accuracy (82,8%), sensitivity (78%), and AUC (0,73). Regarding specificity and sensitivity, RF showed better performance than the other algorithms in the external validation and the highest AUC. LR showed lower performance compared with RF, SVM, or KNN. The outcome of children living with perinatally acquired HIV can be predicted with considerable accuracy using ML algorithms. Better models would benefit less specialized staff in limited resources countries to improve prompt referral in case of high-risk clinical progression.

Abstract
Objectives: Retaining on antiretroviral therapy is essential for reducing HIV-related morbidity and mortality. However, attrition in HIV-positive children remains a critical challenge in resource-limited settings, including Ethiopia. This study aims to determine the incidence and predictors of attrition among children on antiretroviral therapy at the University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia. Methods: An institution-based retrospective follow-up study was conducted among 357 HIV-positive children at the University of Gondar Comprehensive Specialized Hospital from 1 January 2005 to 30 December 2018 (G.C.). Data were collected by chart review using a structured and pre-tested data abstraction checklist. SPSS 22 and STATA 14.0 were used for data entry and analysis, respectively. In the Cox proportional hazard model, bivariables had a 0.25 computed to multivariable, and variables with a p-value of 0.05 at a 95% confidence interval were considered statistically significant predictors of attrition incidence. Results: A total of 344 child records with a completeness rate of 96.4% were reviewed and included in the analysis. The median follow-up period was 4.3 (interquartile range = 4.3 ± 4.7) years, and the median survival time was 132 months. The incidence rate of attrition was 6.6 per 100 person year observation (PYO) (95% confidence interval = 5.5, 8.0). In all, 105 (30.5%) children were recorded as attrition in the follow-up period. Baseline WHO clinical staging 3 and 4 (adjusted hazard ratio = 2.3 (95% confidence interval = 1.3, 4.0)), baseline weight-for-age −2 Z-score (adjusted hazard ratio = 3.1 (95% confidence interval = 1.7, 5.3)), cotrimoxazole non-users (adjusted hazard ratio = 2.5 (95% confidence interval = 1.4, 4.3)), and baseline hemoglobin levels 10 mg/dL (adjusted hazard ratio = 2.7 (95% confidence interval = 1.5, 47)) were found to be a predictor of attrition. Conclusion: The overall incidence of the rate of attrition was high. Baseline WHO clinical staging 3/4, baseline hemoglobin 10 mg/dL, cotrimoxazole (cotrimoxazole preventive therapy) non-user, and underweight at baseline (weight-for-age 2 Z-score) were found to be the main predictors of attrition.

Abstract
Background HIV testing and treatment guidelines for children in sub-Saharan Africa have evolved over time, such that children are now treated at younger ages. The objective of this study was to describe the treatment experience for immunologic, virologic, and growth outcomes among HIV-infected Zambian children younger than 5 years of age from 2008 to 2018. Methods Participants enrolled in a clinical cohort study in Macha, Zambia and initiating antiretroviral treatment before 5 years of age between 2008 and 2015 were included in the analysis and followed up to the end of 2018. Outcomes, including growth, CD4+ T-cell percentage, viral suppression, and mortality, were evaluated among all children using longitudinal and survival analyses. Comparisons by age at treatment initiation (< 1, 1 to < 2, and 2 to < 5 years) were also evaluated. Results Three hundred eighty-one children initiating treatment before 5 years of age between 2008 and 2015 were included in the analysis. Growth metrics and CD4+ T-cell percentage improved over time after treatment initiation. However, 20% of children remained underweight and 40% of children remained stunted after the first 36 months of treatment. 85% of children had a viral load < 400 copies/mL after 12 months of treatment. However, children < 1 year at treatment initiation were more likely to have a detectable viral load in the first 12 months of treatment and less likely to achieve viral suppression compared to older children. Mortality was highest in the first 12 months of treatment, among underweight children, and among children initiating treatment in 2008–2010 compared to 2011–2015. Conclusions Most children initiating antiretroviral treatment from 2008 to 2015 in rural Zambia responded well to treatment. However, many children remained underweight and stunted, and experienced high mortality rates during the first few months of treatment. This supports continued efforts to improve early infant diagnosis, nutritional support, and pediatric drug formulations.

Abstract
INTRODUCTION While access to highly active antiretroviral therapy (HAART) for children with HIV has expanded and the use of HAART has substantially reduced the morbidity and mortality of children due to HIV, poor treatment outcomes among children with HIV are still a major public health problem globally. The aim of this systematic review and meta-analysis is to quantify treatment outcomes among children with HIV. METHODS AND ANALYSIS Systematic searches will be conducted in three electronic databases (PubMed, SCOPUS and Web of Science) for recent studies published from 01 Jan 2000 up to 28 October 2020, without geographical restriction. The primary outcomes of the study will be poor treatment outcomes, which include death, treatment failure and loss to follow-up. We will include quantitative studies that report treatment outcomes among children under the age of 18 years with HIV. Studies will be excluded if they are case report, case series, conducted among adults only or do not provide data on treatment outcomes for children. Two researchers will screen the titles and abstracts of all citations identified in our search, then review the full text of the remaining papers to identify those that meet the inclusion criteria. The Newcastle-Ottawa Scale will be used for quality assessment. A random-effects meta-analysis will be used to obtain pooled estimates of the proportion of poor treatment outcomes. The heterogeneity between studies will be checked visually by using forest plots and quantitatively measured by the index of heterogeneity (I2). Pooled estimates of poor treatment outcomes will be calculated with a random-effects model. Subgroup analysis will be conducted by study settings, treatment regimen, comorbidity (such as tuberculosis), study period and HIV type (HIV-1 and HIV-2). ETHICS AND DISSEMINATION Ethical approval will not be required for this study as it will be based on published papers. The final report of this review will be published in a peer-reviewed scientific journal.

Abstract
Background Management of HIV-infected children on a long-term basis is a challenge in resource-limited countries. The aim of this study is to evaluate the long-term outcome and identify the risk factors for mortality in a cohort of children with antiretroviral therapy (ART) in Vietnam. Patients and Methods A retrospective cohort study was conducted in children aged 0-15 years, seen at the outpatient clinic of the Women and Children Hospital of An Giang, Vietnam, from August 2006 to May 2019. Cox proportional-hazard models were used to determine factors associated with mortality. Results A total of 266 HIV-infected children were on ART. During 1545 child-years of follow-up (median follow-up was 5.8 years), 28 (10.5%) children died yielding a mortality rate of 1.8 death per 100 child-years. By multivariate analysis, World Health Organization clinical stage 3 or 4 (AHR; 7.86, 95% CI; 1.02-60.3, P= 0.047), tuberculosis (TB) co-infection (AHR; 6.26, 95% CI; 2.50-15.64, P= 0.001) and having severe immunosuppression before ART (AHR; 11.73, 95% CI; 1.52-90.4, P= 0.018) were independent factors for mortality in these children. Conclusion Antiretroviral therapy has reduced mortality in HIV-infected children in resource-limited settings. Independent risk factors for mortality were advanced clinical stage (3 or 4), TB co-infection and severe immunosuppression. Early investigation and treatment of TB co-infection allow early ART initiation which may improve outcomes in our settings.

Abstract
Background Though highly active antiretroviral therapy (HAART) has been available for more than a decade in Ethiopia, information regarding mortality rates of human immunodeficiency virus (HIV)-positive children after antiretroviral therapy antiretroviral therapy (ART) initiation is very scarce. Thus, this study intends to determine the predictors of mortality among HIV-positive children receiving ART in Amhara Region. Methods A multicenter facility-based historical cohort study was conducted in 538 HIV-positive children on ART from January 2012 to February 2017. We employed a standardized data extraction tool, adapted from ART entry and follow-up forms. Descriptive analyses were summarized using the Kaplan-Meier survival curve and log rank test. Then, the Cox-proportional hazard regression model was employed to estimate the hazard of death up to five-years after ART initiation. Variables with p-values ≤0.25 in bivariable analysis were candidates to the multivariable analysis. Finally, variables with p-values < 0.05 were considered as significant variables. Results The cohort contributed a total follow-up time of 14,600 child-months, with an overall mortality rate of 3.2 (95% CI: 2.3, 4.3) per 100 child-years. This study also indicated that HIV-infected children presenting with opportunistic infections (OIs) (AHR: 2.5, 95% CI: 1.04, 5.9), anemia (AHR: 3.1, 95% CI: 1.4, 6.7), severe immunodeficiency (AHR: 4.4, 95% CI: 1.7, 11.7), severe stunting (AHR: 3.3, 95% CI: 1.4, 8.0), severe wasting (AHR: 3.1, 95% CI: 1.3, 7.3), and advanced disease staging (III and IV) (AHR: 3.0, 95% CI: 1.2, 7.1) were at higher risk of mortality. Conclusion A higher rate of mortality was observed in our study as compared to previous Ethiopian studies. HIV-positive children presenting with anemia, OIs, severe immunodeficiency, advanced disease staging (III and IV), severe stunting, and severe wasting were at higher risk of mortality.

Abstract
Background: With the successful introduction of ART, the life expectancy of children living with HIV (CLHIV) is substantially increased. However, strict compliance is a necessary step to begin with as noncompliance is again associated with its own demerits of incomplete suppression and decreasing the overall survival of the patients. Aims: The aim of this study was to measure factors associated with adherence to ART among CLHIV. Materials and Methods: This is a 1-year follow-up study conducted from November 2012 to December 2013. A total of 171 children between 18 months and 15 years living with HIV and on ART attending the two ART centers of Delhi were enrolled in the study. Adherence and factors affecting adherence were obtained from the study participants using a semi-structured interview schedule. Statistical Analysis Used: Collected data were transformed into variables and analyzed into SPSS. All observations were in terms of mean, median, standard deviations, percentages, and proportions. Tests of significance such as Chi-square test and t-test were applied wherever required. Results: In nearly 89% of the study participants, adherence to ART was ≥95% at the end of the study. The most common reason for nonadherence was forgetfulness (59%), and 57% of the parents/caretakers were facing monetary problems. Long distance, greater duration to reach center, and unavailability of the parents/caretakers were also quoted as problems. Conclusion: Adherence is genesis to successful treatment outcome and is strongly associated with availability of support by their parents/caretakers. Professional help along with guidance and encouragement is required not only at the caretaker level but also to the family as a whole.

Abstract
Evidence for why antiretroviral therapy (ART) outcomes differ by gender in developing countries has been inconclusive. In this first study to assess 10-year survival on ART in Kenya, our objective was to compare gender differences in survival for those who began ART as adults and as children. Kakamega County Referral Hospital (KCRH) is a tertiary rural hospital that has provided public ART to Kenyans since 2004. All patients enrolled in ART at KCRH who died between July 2004 and March 2017 and a sample of living patients were included in a survival analysis that bootstrapped sampled data. Case-cohort regressions identified adjusted hazard ratios. In total, 1360 patients were included in the study. Ten-year survival was 77% (95% confidence band [CB] 73-81%), significantly different for men (65%; 95% CB: 45-74%) and women (83%; 95% CB: 78-86%) who began therapy as adults. Ten-year survival was intermediate with no significant gender difference (76%; 95% CB: 69-81%) for patients who began therapy as children. Hazard of death was increased for men (hazard ratio [HR] 1.56; 95% confidence interval [CI] 1.13-2.17), infants (HR 2.87; 95% CI 1.44-5.74), patients with consistently poor clinic attendance (HR 3.94; 95% CI 3.19-4.86), and divorced patients (HR 2.25; 95% CI 1.19-4.25). Tuberculosis, diarrheal illnesses, human immunodeficiency virus (HIV) wasting syndrome, and malaria were leading causes of death. Survival was significantly lower for men than for women in all time periods, but only for patients who began therapy as adults, indicating against biological etiologies for the gender mortality difference.

Abstract
Background: Research conducted before the introduction of anti-retroviral therapy (ART), showed that the majority of children living with HIV (CLHIV) would die before their second birthday. In Zambia, ART was rolled out to the public health system in 2004 with subsequent improved survival in CLHIV. However, the survival rates of CLHIV on ART in Zambia since 2004 have not been extensively documented. We assessed survival experiences and the factors associated with survival in CLHIV on ART in Zambia. Methods: We conducted a retrospective cohort analysis of CLHIV (aged up to 15 years) using routinely collected data from health facilities across Zambia, over 13 years to ascertain mortality rates. We explored survival factors using Cox regression giving adjusted hazard ratios (AHR) and 95% confidence intervals (95% CI). Nelson Aalen estimates were used to show the cumulative hazards of mortality for different levels of explanatory factors. Results: A total of 65,448 eligible children, were initiated on ART between 2005 and 2018, of which 33,483 (51%) where female. They contributed a total survival time of 275,715-person years at risk during which 3,265 children died which translated into an incidence rate of 1.1 deaths per 100 person-years during the review period. Mortality rates were highest in children in the first year of life (Mortality rate 2.24; 95% CI = 2.08–2.42) and during the first year on ART (Mortality rate 3.82 95% CI = 3.67–3.98). Over 50% of the children had been on ART for 5–10 years by 2018, and they had the lowest risk of mortality compared to children who had been on ART for <5 years. Conclusions: Children with HIV in Zambia are surviving much longer than was predicted before ART was introduced 14 years ago. This key finding adds to the literature on analysis of survival in CLHIV in low income settings like Zambia. However, this survival is dependent on the age at which ART is initiated and the time on ART highlighting the need to increase investments in early infant diagnosis (EID) to ensure timely HIV testing and ART initiation for CLHIV.

Lancet Glob Health 2019; 7:e1728-e1735. [PMID: 31653591 PMCID: PMC7024990 DOI: 10.1016/s2214-109x(19)30425-5] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2019] [Revised: 08/16/2019] [Accepted: 09/12/2019] [Indexed: 11/24/2022]
Abstract
BACKGROUND Neurological impairments might significantly contribute to reduced life expectancy in low-income and middle-income countries (LMICs). There are no empirical studies of premature mortality in children with neurological impairments in Africa. This study estimated the risk of premature mortality in children with neurological impairments and identified risk factors and causes of death. METHODS We did a cohort study based on a two-stage epidemiological survey in the Kilifi Health and Demographic Surveillance System (Kilifi, Kenya). Study participants were children aged 6-9 years. In the first stage, five trained field workers administered a low-cost screening tool to a random sample of households. In the second stage, we assessed for neurological impairments in five domains (epilepsy, cognitive impairments, vision impairments, hearing impairments, and motor impairments) using comprehensive clinical evaluation and extensive neuropsychological assessments. From the two-stage survey we identified a cohort of children with neurological impairment and a cohort of matched controls. We also enrolled an age-matched sample from the general population. The primary outcome was all-cause mortality. Mortality rates, standardised mortality ratio (SMR), and hazard ratios (HR) for risk factors were estimated and causes of death identified. FINDINGS We enrolled 306 children with neurological impairment, 9912 survey controls, and 22 873 age-matched participants from the general population, and followed up the cohorts between June 1, 2001, and Aug 31, 2018. Median follow-up was 14·5 years (IQR 8·6-17·2). 11 (3·9%) of 284 children with neurological impairment, 92 (1·0%) of 9009 controls, and 272 (1·2%) of 22 873 participants in the general population sample died during the follow-up. Overall mortality rates were 309·8 per 100 000 person-years of observation (95% CI 126·7-492·9) in children with neurological impairment, 80·8 per 100 000 person-years of observation (64·3-97·3) in controls, and 98·8 per 100 000 person-years of observation (87·1-110·6) in the general population sample (mortality rate ratio 3·83, 95% CI 2·05-7·16, p<0·001, compared with controls; 3·13, 1·71-5·72, p<0·001, compared with the general population). Mortality risk in children with neurological impairment was not dependent on the severity of impairment (p=0·291) nor on a specific neurological impairment domain (p=0·205). The overall risk of death adjusted for age and sex was higher in children with neurological impairment compared with controls (HR 4·24, 95% CI 2·26-7·94, p=0·002). An SMR of 3·15 (95% CI 1·66-5·49) was obtained after using the general population sample as the reference for indirect standardisation. In multivariable risk factor analysis, developmental delay (adjusted HR 18·92, 95% CI 2·23-160·44, p=0·007) and severe malnutrition (20·92, 3·14-139·11, p=0·002) increased the risk of mortality in children with neurological impairment. Infections such as HIV/AIDS and accidents were common among all decedents. INTERPRETATION The risk of premature mortality was higher in children diagnosed with neurological impairments compared with the general population and was increased by developmental delay and severe malnutrition. Child development and nutritional status should be assessed in all children in LMICs and tailored interventions started to improve outcomes. FUNDING Wellcome Trust, DELTAS Africa Initiative.

Abstract
BACKGROUND Previous studies have developed methodologies for predicting the number of CD4+ cells from the total leukocyte and lymphocytes count based on mathematical methodologies, obtaining percentages of effectiveness prediction higher than 90% with a value of less than 5000 leukocytes. OBJECTIVE To improve the methodology probabilities prediction in 5000-9000 leukocytes ranges. METHOD from sets A, B, C and D defined in a previous study, and based on CD4+ prediction established on the total number of leukocytes and lymphocytes, induction was performed using data from 10 patients with HIV, redefining the sets A and C that describe the lymphocytes behavior relative to leukocytes. Subsequently, we evaluated with previous research prediction probabilities parameters from a sample of 100 patients, calculating the belonging probability to each sample and organized in predetermined ranges leukocytes, of each of the sets defined, their unions and intersections. Then the same procedure was performed with the new sets and the probability values obtained with the refined method were compared with respect to previously defined, by measures of sensitivity (SENS) and Negative Predictive Value (NPV) for each range. RESULTS probabilities with values greater than 0.83 were found in five of the nine ranges inside the new sets. The probability for the set A∪C increased from 0.06 to 0.18 which means increases between 0.06 and 0.09 for the intersection (A∪C) ∩ (B∪D), making evident the prediction improvement with new sets defined. CONCLUSION The results show that the new defined sets achieved a higher percentage of effectiveness to predict the CD4+ value cells, which represents a useful tool that can be proposed as a substitute for clinical values obtained by the flow cytometry.

Although early antiretroviral therapy (ART) reduces HIV-related mortality in children by up to 75%, almost half of HIV-positive children younger than 1 year old in Swaziland do not initiate ART. This study was conducted to identify barriers to early ART initiation among HIV-positive infants. This was a case-control study among HIV-positive infants, aged 2 to 18 months, who either did not initiate ART (cases), or initiated ART (controls), during 18 months after testing. Multivariable logistic regression showed that infants who visited the clinic every month, or every 2 months, were 5.78 and 6.20 times more likely to initiate ART than those who visited less often (OR 5.78, 95% CI 1.82-18.33 and OR 6.20, 95% CI 1.30-29.60 respectively). Children who lived ≤30 and 31-60 minutes from the nearest clinic were 84% and 79% less likely respectively to initiate ART (OR 0.16, 95% CI 0.03-0.78 and OR 0.21, 95% CI 0.04-0.98) compared with those who lived more than 60 minutes away. Children who received immunisation after 6 months were 22.59 times more likely to initiate ART (OR 22.59, 95% CI 7.00-21.72) than those who did not. Infants of caregivers who had excellent or good relationships with their healthcare provider were 4.32 times more likely to initiate ART (OR 4.32, 95% CI 1.01-18.59) than those of caregivers who had average or poor relationships with healthcare providers. The significant predictors of ART initiation identified in this study should be regarded as priority areas for intervention among HIV-positive women in Swaziland.

Abstract
This methodological article reflects on the contribution audio diaries can make to accessing important, and commonly silenced, dimensions of the lived experience of growing up with HIV and their acceptability to children. Audio diaries were used by 12 young people, aged 11 to 13 years, as part of a longitudinal qualitative study embedded within the Anti-Retroviral Research for Watoto (ARROW) clinical trial. The method provided an alternative means for young people to express detailed reflections on their day-to-day encounters, as well as ordinarily silenced topics, including hidden and suppressed emotions regarding the circumstance surrounding their perinatal infection. Although the audio diary has great potential as method, its efficacy rests on young people's understanding of how to use it. There are ethical challenges around maintaining confidentiality while participants are in possession of the diaries and provision of appropriate support. The technology used in the study was in many ways cumbersome compared with opportunities increasingly available.

SAGE Open Med 2019; 7:2050312119838957. [PMID: 30937168 PMCID: PMC6434434 DOI: 10.1177/2050312119838957] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2018] [Accepted: 02/28/2019] [Indexed: 12/22/2022] Open
Abstract
Objective: To determine the survival rate and predictors of HIV-infected children on antiretroviral therapy at two selected facilities in North Ethiopia. Methods: A facility-based retrospective cohort study was conducted in Debre Tabor General Hospital and Dessie Referral Hospital from December 2005 to November 2015. A total of 426 records were included in the study. Multivariable Cox proportional hazards regression model was used to identify independent predictors of survival. Results: At the end of follow-up, 97 (22.9%) HIV-infected children died and 325 (77.1%) were alive. The probabilities of survival at 12, 24, 36 and 48 months of on antiretroviral therapy were 0.91, 0.85, 0.84 and 0.80, respectively. The median survival time was 91.6 months (95% confidence interval: 89.0–94.2). Almost half (51%) of the deaths occurred within the first 2 years of treatment. Study participants who had poor adherence to antiretroviral therapy (adjusted hazard ratio = 3.0; 95% confidence interval: 1.2–7.5) and who started antiretroviral therapy with lower baseline weight-for-age Z-score (adjusted hazard ratio = 2.5; 95% confidence interval: 1.1–6.1) were significantly associated with high risk of mortality. On the other hand, study participants with a baseline CD4 count above 200 cells/mm3 (adjusted hazard ratio = 0.7; 95% confidence interval: 0.4–0.9) and those participants who had psychosocial support during follow-up (adjusted hazard ratio = 0.03; 95% confidence interval: 0.1–0.7) were significantly associated with less mortality event. Conclusion: Mortality of children on antiretroviral therapy was high. The risk of mortality is increased if the child was underweight at the commencement of antiretroviral therapy, had lower baseline CD4 count, had poor adherence to antiretroviral therapy and had no psychosocial support. Concerned stakeholders should focus on antiretroviral therapy adherence, nutritional interventions, psychological support and early initiation of antiretroviral therapy regardless of their CD4 count to enhance survival of HIV-infected children on antiretroviral therapy.

Rapid Serological Tests Ineffectively Screen for HIV Exposure in HIV-Positive Infants. J Acquir Immune Defic Syndr 2019; 77:331-336.

Abstract
BACKGROUND Data on the performance and utility of rapid serological tests in infants to determine HIV exposure are unclear and in some instances contradictory. This study sought to understand the performance of rapid serological tests in high HIV burden, high Option B+ coverage settings to be used as an HIV exposure screening tool. METHODS A total of 3600 infants up to 24 months of age at 4 regional hospitals in Uganda were systematically enrolled and tested simultaneously using both HIV rapid serological and nucleic acid-based tests. RESULTS Only 58 of the 94 HIV-positive infants who received both rapid serological and nucleic acid-based tests were positive with the rapid serological test (sensitivity: 61.7%; 95% confidence interval: 51.1 to 71.5). Using rapid serological tests to screen infants for exposure to HIV and follow-up nucleic acid-based testing would have missed 38.3% (36 of 94) of HIV-positive infants. Finally, several HIV-positive infants who were negative by rapid serological test presented to well-child entry points and were considered healthy. All 3 HIV-positive infants presenting to outreach and immunization were negative by rapid serological testing and 73% (8 of 11) presenting to outpatient. CONCLUSIONS These data suggest that the use of rapid serological tests may have inadequate performance as an indicator of exposure and potential HIV infection among infants presenting at both well-child (immunization and community outreach) and sick-infant (nutrition and inpatient) entry points. To improve the identification of HIV-positive infants, nucleic acid-based testing should instead be considered in infants aged younger than 18 months.

Abstract
BACKGROUND Prompt child HIV testing and treatment is critical; however, children are often not diagnosed until symptomatic. Understanding factors that influence pediatric HIV testing can inform strategies to increase testing. METHODS A mixed-methods study was conducted at a tertiary hospital in Nairobi, Kenya. Three focus group discussions with health care workers (HCWs) and 18 in-depth interviews with HIV-infected adults with children of unknown status were analyzed using thematic analysis. A structured questionnaire was administered to 116 HIV-infected caregivers of children of unknown status to triangulate qualitative findings. RESULTS Analysis revealed 3 key periods of the pediatric HIV testing process: decision to test, test visit, and posttest. Key issues included: decision to test: inaccurate HIV risk perception for children, challenges with paternal consent, lack of caregiver HIV status disclosure to partners or older children; test experience: poor understanding of child consent/assent and disclosure guidelines, perceived costs of testing and care, school schedules, HCW discomfort with pediatric HIV testing; and posttest: pessimism regarding HIV-infected children's prognosis, caregiver concerns about their own emotional health if their child is positive, and challenges communicating about HIV with children. Concerns about all 3 periods influenced child testing decisions. In addition, 3 challenges were unique to pediatric HIV: inaccurate HIV risk perception for children; disclosure, consent, and permission; and costs and scheduling. CONCLUSIONS Pediatric HIV testing barriers are distinct from adult barriers. Uptake of pediatric HIV testing may be enhanced by interventions to address misconceptions, disclosure services, psychosocial support addressing concerns unique to pediatric testing, child-focused HCW training, and alternative clinic hours.

Temporal Improvements in Long-term Outcome in Care Among HIV-infected Children Enrolled in Public Antiretroviral Treatment Care: An Analysis of Outcomes From 2004 to 2012 in Zimbabwe. Pediatr Infect Dis J 2018; 37:794-800.

Abstract
BACKGROUND Increasing numbers of children are requiring long-term HIV care and antiretroviral treatment (ART) in public ART programs in Africa, but temporal trends and long-term outcomes in care remain poorly understood. METHODS We analyzed outcomes in a longitudinal cohort of infants (<2 years of age) and children (2-10 years of age) enrolling in a public tertiary ART center in Zimbabwe over an 8-year period (2004-2012). RESULTS The clinic enrolled 1644 infants and children; the median age at enrollment was 39 months (interquartile range: 14-79), with a median CD4% of 17.0 (interquartile range: 11-24) in infants and 15.0 (9%-23%) in children (P = 0.0007). Among those linked to care, 33.5% dropped out of care within the first 3 months of enrollment. After implementation of revised guidelines in 2009, decentralization of care and increased access to prevention of mother to child transmission services, we observed an increase in infants (48.9%-68.3%; P < 0.0001) and children (48.9%-68.3%; P < 0.0001) remaining in care for more than 3 months. Children enrolled from 2009 were younger, had lower World Health Organization clinical stage, improved baseline CD4 counts than those who enrolled in 2004-2008. Long-term retention in care also improved with decreasing risk of loss from care at 36 months for infants enrolled from 2009 (aHR: 0.57; 95% confidence interval: 0.34-0.95; P = 0.031). ART eligibility at enrollment was a significant predictor of long-term retention in care, while delayed ART initiation after 5 years of age resulted in failure to fully reconstitute CD4 counts to age-appropriate levels despite prolonged ART. CONCLUSIONS Significant improvements have been made in engaging and retaining children in care in public ART programs in Zimbabwe. Guideline and policy changes that increase access and eligibility will likely to continue to support improvement in pediatric HIV outcomes.

Abstract
Outcomes of HIV-infected children have improved dramatically over the past decade, but are undermined by patient loss to follow-up (LTFU). We assessed patterns of LTFU among HIV-infected children receiving antiretroviral treatment (ART) at a large inner-city HIV clinic in Johannesburg, South Africa between 2005 and 2014.Demographic and clinical data were extracted from clinic records of children under 12 years. Differences between characteristics of children retained in care and LTFU were assessed using Wilcoxon rank sum tests or Pearson χ tests. Cox proportional hazard models then identified characteristics associated with LTFU.Of 135 children, the median age at ART initiation was 21.5 months (IQR: 6.3-47.7) with a median follow-up time of 3.3 years (IQR: 1.4-5.0). The incidence rate of LTFU was 10.8 per 100 person-years (95% CI: 8.2-14.4); cumulatively 36% of children were LTFU. Almost a third (n = 39) of children missed a clinic visit, but then returned to care; 77% of these were eventually LTFU. In total, 18% of children had elevated viral loads after 6 or more months of ART. Older age at ART initiation (18-59 months: aHR 1.6, 95% CI: 3.9-14.2) and ever missing a clinic visit (aHR 7.4 95% CI: 3.9-14.2) were independent predictors of LTFU.High rates of LTFU were observed in this primary care clinic. Risks for LTFU included older age (>18 months old) and missed clinic visits. Identifying children who miss scheduled visits and developing strategies directed at retaining them in care is critical to improving long-term pediatric HIV outcomes.

Abstract
Purpose: To assess how the infrastructure improvements supported by the US Centers for Disease Control and Prevention (CDC) and the United States President’s Emergency Plan for AIDS Relief (PEPFAR) contributed to facility-level quarterly and annual new patient enrolment in HIV care and treatment and antiretroviral therapy (ART) uptake and retention in care.Methods: Aggregate quarterly and annual facility-based HIV care and treatment data from the CDC-managed PEPFAR Reporting Online and Management Information System database collected between 2005 and 2012 were analysed for the 11 rural and 32 urban facilities that met the eligibility criteria. Infrastructure improvements, including both renovations and new construction, occurred on different dates for the facilities; therefore, data were adjusted such that pre- and post-infrastructure improvements were aligned and date-time was ignored. The analysis calculated the mean (95% confidence interval) number of patients per facility who were (1) newly enrolled in HIV care, (2) patients initiated on ART, (3) patients retained in care, defined as alive and on ART, and (4) reasons for attrition, defined as transferred out, lost to follow-up, deceased or stopped ART.Results: The overall mean number of adult patients newly enrolled in HIV care clinics per quarter declined from 187.7 (151.4–223.9) to 135.2 (117.4–152.9) after infrastructure improvements but was not statistically significant (p = 0.20). However, the mean number of patients who were alive and remained on ART increased from 193.2 (145.3–241.1) to 273.2 (219.0–327.3) after improvements in both rural and urban facilities, although not significantly (p = 0.59). A similar picture was observed for overall paediatric enrolment and retention in care. Health facility-specific case studies show variations in new patient enrolment and retention in care between health facilities depending on the catchment area, population HIV prevalence and coverage of ART facilities. Regarding attrition, the mean number of adult patients lost to follow-up changed from 76.6 (20.8–132.3) to 139.4 (79.6–199.1) (p = 0.65) among rural facilities, while the mean number of children lost to follow-up increased significantly from 3.4 (0.5–6.3) to 8.7 (5.0–12.3) (p = 0.02) after improvements.Conclusion: Patient retention in care improved in HIV care and treatment facilities with infrastructure improvements. However, the overall number of patients newly enrolled and initiated on ART declined and attrition increased in facilities after improvements.

Abstract
BACKGROUND Data on pediatric HIV in Peru are limited. The National Institute of Child Health (Instituto Nacional de Salud del Niño: INSN) cares for the most HIV-infected children under the age of 18 years in the country. We describe the outcomes of children seen at INSN's HIV clinic over the 10 years when antiretroviral therapy and prevention of mother-to-child transmission (PMTCT) interventions became available in 2004. METHODS We conducted a retrospective review of INSN HIV clinic patients between 2003 and 2012. Deidentified data were collected and analyzed. RESULTS A total of 280 children were included: 50.0% (140/280) were male; 80.0% (224/280) lived in metropolitan Lima. Perinatal transmission was the mode of HIV infection in 91.4% (256/280) of children. Only 17% (32/191) of mothers were known to be HIV-infected at delivery; of these mothers, 41% (13/32) were receiving antiretroviral therapy at delivery, 72% (23/32) delivered by Cesarean section and 47% (15/32) of their infants received antiretroviral prophylaxis. Median age at HIV diagnosis for all children was 35.7 months (interquartile range 14.5-76.8 months), and 67% (143/213) had advanced disease (clinical stage C). After HIV diagnosis, the most frequent hospitalization discharge diagnoses were bacterial pneumonia, chronic malnutrition, diarrhea, anemia and tuberculosis. Twenty-four patients (8.6%) died at a median age of 77.4 months. CONCLUSIONS Most cases of pediatric HIV were acquired via perinatal transmission; few mothers were diagnosed before delivery; and among mothers with known HIV status, PMTCT was suboptimal even after national PMTCT policy was implemented. Most children were diagnosed with advanced disease. These findings underscore the need for improving early pediatric HIV diagnosis and treatment, as well as PMTCT strategies.

Abstract
Background Myanmar National AIDS programme’s priority is to improve the survival of all people living with HIV by providing anti-retroviral therapy (ART) care. More than 7200 children (aged <15 years) have been enrolled into ART care from 2005 to 2016. A previous study showed that ~11% children on ART care had either died or were lost to follow-up by 60 months. Factors associated with death and lost-to follow-up (adverse outcomes) have not been previously studied. Objectives To describe the association between demographic and clinical characteristics at enrollment into ART care with adverse outcomes. Methods Cohort study using records of children enrolled for ART care at Mingalardon Specialist Hospital (main Paediatric ART center in Myanmar) from 2006–2016. We used multivariable Cox proportional hazards regression models for analysis. Results 1,159 children were enrolled for ART care and they contributed a total of 1.45 million person-days of follow-up period. 112 (10%) had an adverse outcome during the follow-up time period (55 deaths, 57 lost to follow-up). Enrollment into the ART care through in-patient care department of the hospital, CD4 Cell count <50/mm3, enrollment during changing ART guidelines (different ART eligibility criteria and preferred ART regimen) were independently associated with higher hazards of adverse outcome. Receiving protease inhibitor-based ART regimen at enrollment was independently associated with lower hazards of adverse outcome. Age, sex, residing in urban or rural areas, WHO clinical stage, having TB at the time of enrollment, receiving cotrimoxazole prophylaxis were not statistically associated with adverse outcomes. Conclusion Our analysis reconfirms good survival of children on ART care (including those with TB). The characteristics associated with adverse outcomes (other than CD4 cell count<50) are surrogates of some unmeasured underlying health system/ patient related factors that needs further exploration to improve the survival of children on ART care.

Abstract
BACKGROUND Data are scarce on the long-term clinical outcomes of perinatally HIV-infected children and adolescents receiving antiretroviral therapy (ART) in low/middle-income countries. We assessed the incidence of mortality before (early) and after (late) 6 months of ART and of the composite outcome of new/recurrent AIDS-defining event or death >6 months after ART start (late AIDS/death) and their associated factors. METHODS Study population was perinatally HIV-infected children (≤18 years) initiating ART within the Program for HIV Prevention and Treatment observational cohort (NCT00433030). Factors associated with late AIDS/death were assessed using competing risk regression models accounting for lost to-follow-up and included baseline and time-updated variables. RESULTS Among 619 children, "early" mortality incidence was 99 deaths per 1000 person-years of follow-up [95% confidence interval (CI): 69 to 142] and "late" mortality 6 per 1000 person-years of follow-up (95% CI: 4 to 9). Of the 553 children alive >6 months after ART initiation, median age at ART initiation was 6.4 years, CD4% 8.2%, and HIV-RNA load 5.1 log10 copies/mL. Thirty-eight (7%) children developed late AIDS/death after median time of 3.3 years: 24 died and 24 experienced new/recurrent AIDS-defining events (10 subsequently died). Factors independently associated with late AIDS/death were current age ≥13 years (adjusted subdistribution hazard ratio 4.9; 95% CI: 2.4 to 10.1), HIV-RNA load always ≥400 copies/mL (12.3; 95% CI: 4.0 to 37.6), BMI-z-score always <-2 SD (13.7; 95% CI: 3.4 to 55.7), and hemoglobin <8 g/dL at least once (4.6; 95% CI: 2.0 to 10.5). CONCLUSIONS After the initial 6 months of ART, being an adolescent, persistent viremia, poor nutritional status, and severe anemia were associated with poor clinical outcomes. This supports the need for novel interventions that target children, particularly adolescents with poor growth and uncontrolled viremia.

Abstract
HIV/AIDS remains one of the leading causes of death among children under 5 years old in Swaziland. Although studies have shown that early initiation of infants and children diagnosed with HIV on antiretroviral therapy (ART) significantly reduces mortality, many children do not initiate ART until the later stages of disease. This study was designed to collect qualitative data from mothers and caregivers of HIV-positive children to identify the barriers to ART initiation. Focus group discussion (FGD) sessions were conducted in siSwati between July and September 2014 among caregivers of aged children 2-18 months in Swaziland who did or did not initiate ART between January 2011 and December 2012 after HIV DNA PCR-positive diagnosis of the infants. Denial, guilt, lack of knowledge, tuberculosis (TB)/HIV co-infection, HIV-related stigma, lack of money, and distance to clinics were reported by the participants as barriers to ART initiation. The findings further revealed that non-initiation on ART was not linked to a negative perception of the treatment. Findings suggest a need to improve sensitivity among healthcare workers as well as education and counselling services that will facilitate the ART initiation process.

Abstract
Vertical transmission of HIV is responsible for about 14 % of new HIV cases reported each year in sub-Saharan Africa. Barriers that prevent women from accessing and using antiretroviral medications (ARVs) for themselves and their infants perpetuate the epidemic. To identify influences on access to and use of infant HIV health services, specifically nevirapine administration, we conducted a mixed methods study among HIV-positive women in Uganda. This included a cross-sectional survey (n = 384) and focus group discussions (n = 6, 5-9 participants each). Of the 384 women, 80 % gave nevirapine to their infants within 72 h of birth. Factors independently associated with nevirapine administration were lack of maternal adherence to ARVs (AOR 3.55, 95 % CI 1.36-9.26) and attending a support group (AOR 2.50, 95 % CI 1.06-5.83). Non-health facility births were inversely related to nevirapine use (AOR 0.02, 95 % CI 0.003-0.09). Focus group discussions identified four themes impacting access and use: attending a support group, health care worker attitudes, lack of partner support, and poor health messaging regarding ARVs. Improving health care worker messaging regarding ARVs and providing women with needed support to access and use infant ARV prophylaxis is critical to overcoming access barriers. Eliminating these barriers may prevent numerous HIV infections each year saving the lives of many HIV-exposed infants.

Abstract
OBJECTIVE To assess mortality and loss to follow-up of children with HIV infection who started antiretroviral therapy (ART) through the Universal Coverage Health Program (UC) in Thailand. STUDY DESIGN Children with HIV infection who initiated ART at age <15 years through the UC between 2008 and 2013 were included in the analysis. Death was ascertained through linkage with the National Death Registry. A competing-risks method was used to calculate subdistribution hazard ratios (SHRs) of predictors for loss to follow-up. Death was considered a competing risk. Cox proportional hazards models were used to assess predictors of mortality. RESULTS A total of 4618 children from 497 hospitals in Thailand were included in the study. Median age at ART initiation was 9 years (IQR, 6-12 years), and the median duration of tracking was 4.1 years (a total of 18 817 person-years). Three hundred and ninety-five children (9%) died, for a mortality rate of 2.1 (95% CI, 1.9-2.3) per 100 person-years, and 525 children (11%) were lost to follow-up, for a lost to follow-up rate of 2.9 (95% CI, 2.7-3.2) per 100 person-years. The cumulative incidence of loss to follow-up increased from 4% at 1 year to 8.8% at 3 years. Children who started ART at age ≥12 years were at the greatest risk of loss to follow-up. The probability of death was 3.2% at 6 months and 6.4% at 3 years. Age ≥12 years at ART initiation, lower baseline CD4%, advanced HIV staging, and loss to follow-up were associated with mortality. CONCLUSION The Thai national HIV treatment program has been very effective in treating children with HIV infection, with low mortality and modest rates of loss to follow-up.

Abstract
PURPOSE OF REVIEW It is 20 years since the start of the combination antiretroviral therapy (cART) era and more than 10 years since cART scale-up began in resource-limited settings. We examined survival of vertically HIV-infected infants and children in the cART era. RECENT FINDINGS Good survival has been achieved on cART in all settings with up to 10-fold mortality reductions compared with before cART availability. Although mortality risk remains high in the first few months after cART initiation in young children with severe disease, it drops rapidly thereafter even for those who started with advanced disease, and longer term mortality risk is low. However, suboptimal retention on cART in routine programs threatens good survival outcomes and even on treatment children continue to experience high comorbidity risk; infections remain the major cause of death. Interventions to address infection risk include a cotrimoxazole prophylaxis, isoniazid preventive therapy, routine childhood and influenza immunization, and improving maternal survival. SUMMARY Pediatric survival has improved substantially with cART and HIV-infected children are aging into adulthood. It is important to ensure access to diagnosis and early cART, good program retention as well as optimal comorbidity prophylaxis and treatment to achieve the best possible long-term survival and health outcomes for vertically infected children.

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
OBJECTIVES Evaluation of a novel index case finding and linkage-to-care programme to identify and link HIV-infected children (1-15 years) and young persons (>15-24 years) to care. METHODS HIV-infected patients enrolled in HIV services were screened and those who reported untested household members (index cases) were offered home- or facility-based HIV testing and counselling (HTC) of their household by a community health worker (CHW). HIV-infected household members identified were enrolled in a follow-up programme offering home and facility-based follow-up by CHWs. RESULTS Of the 1567 patients enrolled in HIV services, 1030 (65.7%) were screened and 461 (44.8%) identified as index cases; 93.5% consented to HIV testing of their households and of those, 279 (64.7%) reported an untested child or young person. CHWs tested 711 children and young persons, newly diagnosed 28 HIV-infected persons (yield 4.0%; 95% CI: 2.7-5.6), and identified an additional two HIV-infected persons not enrolled in care. Of the 30 HIV-infected persons identified, 23 (76.6%) were linked to HIV services; 18 of the 20 eligible for ART (90.0%) were initiated. Median time (IQR) from identification to enrolment into HIV services was 4 days (1-8) and from identification to ART start was 6 days (1-8). CONCLUSIONS Almost half of HIV-infected patients enrolled in treatment services had untested household members, many of whom were children and young persons. Index case finding, coupled with home-based testing and tracked follow-up, is acceptable, feasible and facilitates the identification and timely linkage to care of HIV-infected children and young persons.

Abstract
OBJECTIVES Few routine systems exist to test older, asymptomatic children for HIV. Testing all children in the population has high uptake but is inefficient, whereas testing only symptomatic children increases efficiency but misses opportunities to optimize outcomes. Testing children of HIV-infected adults in care may efficiently identify previously undiagnosed HIV-infected children before symptomatic disease. METHODS HIV-infected parents in HIV care in Nairobi, Kenya were systematically asked about their children's HIV status and testing history. Adults with untested children ≤12 years old were actively referred and offered the choice of pediatric HIV testing at home or clinic. Testing uptake and HIV prevalence were determined, as were bottlenecks in pediatric HIV testing cascade. RESULTS Of 10,426 HIV-infected adults interviewed, 8,287 reported having children, of whom 3,477 (42%) had children of unknown HIV status, and 611 (7%) had children ≤12 years of unknown HIV status. After implementation of active referral, the rate of pediatric HIV testing increased 3.8-fold from 3.5 to 13.6 children tested per month (Relative risk: 3.8, 95% confidence interval: 2.3 to 6.1). Of 611 eligible adults, 279 (48%) accepted referral and were screened, and 74 (14%) adults completed testing of 1 or more children. HIV prevalence among 108 tested children was 7.4% (95% confidence interval: 3.3 to 14.1%) and median age was 8 years (interquartile range: 2-11); 1 child was symptomatic at testing. CONCLUSIONS Referring HIV-infected parents in care to have their children tested revealed many untested children and significantly increased the rate of pediatric testing; prevalence of HIV was high. However, despite increases in pediatric testing, most adults did not complete testing of their children.

Abstract
BACKGROUND There are few data on long-term survival of Brazilian children with vertically acquired HIV infection. We assessed survival, mortality risk factors and response to antiretroviral therapy (ART). We compared children with early and late access to care. METHODS We used Kaplan-Meier survival curves with Log-rank tests to compare survival time and mortality rates of 245 HIV vertically infected children admitted for care during 2002-2014. RESULTS Total follow-up sum was 1584.4 person-years. Overall survival was 83.9%. Median age at start of ART was 51.6 (18.0-94.2) months, and median age at death was 8.2 (1.7-10.1) years (mortality rate: 1.7/100 person-years). Pneumonia and sepsis were the main causes of death. Male gender, viral load (VL) ≥100,000 copies, severe immunosuppression, moderate/severe symptoms and history of opportunistic infection were associated with higher mortality in bivariate analysis. Only severe symptoms remained associated in multivariate analysis (P = 0.03). There was no difference in mortality in early compared to late access group. Overall, 217 patients received ART; 192 had a recent VL, of which 116 (59.8%) had ≤400 copies. Variables associated with therapeutic failure were as follows: VL ≥100,000 copies, less immune suppression, age <12 months at admission and age <3 years at ART start. CONCLUSIONS We have a high mortality rate in comparison with developed countries. Although early access did not impact mortality, we detected a trend in favor of early treatment as a protecting factor against mortality. We need to increase adherence to care and treatment, and better drugs to optimize outcomes.

Abstract
OBJECTIVE To assess mortality and clinical outcomes in children treated with antiretroviral therapy (ART) in four African vertical programmes between 2001 and 2010. METHODS Cohort analysis of data from HIV-infected children (<15 years old) initiating ART in four sub-Saharan HIV programmes in Kenya, Uganda and Malawi, between December 2001 and December 2010. Rates of mortality, programme attrition and first-line clinico-immunological failure were calculated by age group (<2, 2-4 and 5-14 years), 1 or 2 years after ART initiation, and risk factors were examined. RESULTS A total of 3949 children, 22.7% aged <2 years, 32.2% 2-4 years and 45.1% 5-14 years, were included. At ART initiation, 60.8% had clinical stage 3 or 4, and 46.5% severe immunosuppression. Overall mortality, attrition and 1-year failure rates were 5.1, 10.8 and 9.0 per 100 person-years, respectively. Immunosuppression, stage 3 or 4, and underweight were associated with increased rates of mortality, attrition and treatment failure. Adjusted estimates showed lower mortality hazard ratios (HR) among children aged 2-4 years (HR = 0.57, 95% CI 0.42-0.77 than children aged 5-14 years). One-year treatment failure incidence rate ratios (IRR) were similar regardless of age (IRR = 0.91, 95% CI 0.67-1.25 for <2 years; 1.01, 95% CI 0.83-1.23 for 2-4 years, vs. 5-14 years). CONCLUSIONS Good treatment outcomes were achieved during the first decade of HIV paediatric care despite the late start of therapy. Encouraging early HIV infant diagnosis in and outside prevention of mother-to-child transmission programmes, and linkage to care services for early ART initiation, is needed to reduce mortality and delay treatment failure.

Abstract
BACKGROUND Pediatric uptake and outcomes in antiretroviral treatment (ART) programmes have lagged behind adult programmes. We describe outcomes from a population-based pediatric ART cohort in rural southern Malawi. METHODS Data were analyzed on children who initiated ART from October/2003 -September/2011. Demographics and diagnoses were described and survival analyses conducted to assess the impact of age, presenting features at enrolment, and drug selection. RESULTS The cohort consisted of 2203 children <15 years of age. Age at entry was <1 year for 219 (10%), 1-1.9 years for 343 (16%), 2-4.9 years for 584 (27%), and 5-15 years for 1057 (48%) patients. Initial clinical diagnoses of tuberculosis and wasting were documented for 409 (19%) and 523 (24%) patients, respectively. Median follow-up time was 1.5 years (range 0-8 years), with 3900 patient-years of follow-up. Over the period of observation, 134 patients (6%) died, 1324 (60%) remained in the cohort, 345 (16%) transferred out, and 387 (18%) defaulted. Infants <1 year of age accounted for 19% of deaths, with a 2.7-fold adjusted mortality hazard ratio relative to 5-15 year olds; median time to death was also shorter for infants (60 days) than older children (108 days). Survival analysis demonstrated younger age at ART initiation, more advanced HIV stage, and presence of tuberculosis to each be associated with shorter survival time. Among children <5 years, severe wasting (weight-for-height z-score </ = -3.0) was also associated with reduced survival. CONCLUSIONS Cumulative incidence of mortality was 5.2%, 7.1% and 7.7% after 1, 3, and 5 years, respectively, with disproportionate mortality in infants <1 year of age and those presenting with tuberculosis. These findings reinforce the urgent need for early diagnosis and treatment in this population, but also demonstrate that provision of pediatric care in a rural setting can yield outcomes comparable to more resourced urban settings of poor countries.

Abstract
BACKGROUND AND OBJECTIVES The mortality rate of HIV-infected children can be reversed under highly active antiretroviral therapy (HAART). The impact of HAART on the mortality of HIV-infected children in Cameroon has not been extensively documented. We aimed to measure the mortality rate of HIV-infected children under HAART and to identify predictive factors of mortality. METHODS Retrospective cohort study of 221 children initiated on HAART from 2005 to 2009 and followed-up until 2013. Survival data was analyzed using Kaplan Meier method and Cox regression model to identify independent predictors of child mortality on HAART. RESULTS Overall, 9.9% of children (n=22) died over a follow-up period of 755 child-years (mortality of 2.9 per 100 child-years); 70% of deaths occurred during the first six months of HAART. The probability of survival after four years of treatment was 88.7% (95% CI=[84.2-93.3]). During the multivariate analysis of baseline variables, we observed that the WHO clinical stages III and IV (HR: 3.55 [1.09-13.6] and HR: 7.7 [3.07-31.2]) and age≤1year at HAART initiation were independently associated with death (HR: 2.1 [1.01-5.08]). Neither orphanhood, baseline CD4 count or hemoglobin level nor low nutritional status predicted death in this cohort. CONCLUSION The mortality of children receiving HAART was low after five years of follow-up and it was strongly associated with WHO stages III and IV and a younger age at treatment initiation.

Retention of HIV-Infected Children in the First 12 Months of Anti-Retroviral Therapy and Predictors of Attrition in Resource Limited Settings: A Systematic Review. PLoS One 2016; 11:e0156506. [PMID: 27280404 PMCID: PMC4900559 DOI: 10.1371/journal.pone.0156506] [Citation(s) in RCA: 35] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2016] [Accepted: 05/16/2016] [Indexed: 02/06/2023] Open
Abstract
Current UNAIDS goals aimed to end the AIDS epidemic set out to ensure that 90% of all people living with HIV know their status, 90% initiate and continue life-long anti-retroviral therapy (ART), and 90% achieve viral load suppression. In 2014 there were an estimated 2.6 million children under 15 years of age living with HIV, of which only one-third were receiving ART. Little literature exists describing retention of HIV-infected children in the first year on ART. We conducted a systematic search for English language publications reporting on retention of children with median age at ART initiation less than ten years in resource limited settings. The proportion of children retained in care on ART and predictors of attrition were identified. Twelve studies documented retention at one year ranging from 71–95% amongst 31877 African children. Among the 5558 children not retained, 4082 (73%) were reported as lost to follow up (LFU) and 1476 (27%) were confirmed to have died. No studies confirmed the outcomes of children LFU. Predictors of attrition included younger age, shorter duration of time on ART, and severe immunosuppression. In conclusion, significant attrition occurs in children in the first 12 months after ART initiation, the majority attributed to LFU, although true outcomes of children labeled as LFU are unknown. Focused efforts to ensure retention and minimize early mortality are needed as universal ART for children is scaled up.

Abstract
BACKGROUND Without antiretroviral therapy (ART), approximately one-half of HIV-infected infants will die by two years. In 2010, the World Health Organization (WHO) recommended that all HIV-infected infants < 24 months be initiated on ART regardless of their clinical/immunologic status. However, there remains little published data detailing cohorts of infants on ART in Sub-Saharan Africa. This study describes baseline characteristics and 12 month outcomes of a cohort of HIV-infected children < 24 months of age at pediatric HIV centers in Mwanza and Mbeya, Tanzania. MATERIALS AND METHODS Retrospective chart review. INCLUSION CRITERIA children < 24 months of age, initiated on ART at Baylor Children s Foundation Tanzania clinics, between March-December 2011. RESULTS Baseline: Ninety-three children were initiated on ART at a median age of 13.4 months. Sixty-seven percent had severe immunosuppression and 31.5% had severe malnutrition. OUTCOME Seventy-three patients were still in care at 12 month follow-up, there were four (4.3%) deaths, five (5.4%) patients transferred, and 11 (11.8%) loss to follow-up. Average CD4% was 32.7 (p < 0.001). Ninety percent of patients were WHO treatment stage I (p < 0.001). Eighty-six percent had normal nutritional status (p < 0.001). CONCLUSION Our cohort of HIV infected children < 24 months initiated on ART did well clinically at 12 month outcomes despite being severely immunocompromised and malnourished at baseline. Nevirapine based regimens had good 12 month clinical outcomes, regardless of maternal exposure. Loss to follow-up rate was high for our cohort, demonstrating the need to develop strong mechanisms to counteract this.

Abstract
OBJECTIVES In settings where CD4 testing is not available, alternative markers to start paediatric anti-retroviral therapy (ART) could be used. A comprehensive evaluation of these markers has not been performed. METHODS Prospective cross-sectional study of HIV-infected Malawian children not eligible for ART based on clinical criteria. Associations between CD4 and alternative markers [haemoglobin, total lymphocyte count (TLC), serum albumin, thrombocytes and growth parameters] were analysed, and accuracy of existing and new cut-offs were evaluated. RESULTS In all, 417 children were enrolled. Of 261 children aged ≥5 years, 155 (59%) qualified to start ART using CD4. In this group, only TLC was associated with CD4 (p < 0.001). Sensitivity for TLC was 21% (95% CI: 15-29%), using World Health Organization cut-offs. Improved cut-offs increased sensitivity to 73% (95% CI: 65-80%), specificity 62% (95% CI: 52-72%). CONCLUSION Clinical staging alone is an unreliable strategy to start ART in children. TLC is the only alternative marker for CD4, cut-offs need to be revised though.

Abstract
Background The scale up of pediatric antiretroviral treatment programs across Sub-Saharan Africa over the last decade has brought increasing numbers of children into HIV care. This patient population requiring life-long care presents new challenges in the outpatient and inpatient settings. We sought to describe hospitalizations from a large pediatric HIV treatment facility to better understand the scope of the situation and identify areas for improved care delivery. Methods We conducted a retrospective case series of all HIV-infected and exposed patients <18 years enrolled at Baylor College of Medicine Children’s Foundation Malawi, from October 2004-October 2010. Patients admitted to the hospital on or after the day of enrollment were included. Data were extracted from electronic clinic records. Analysis was done at the patient and admission level, as some patients had multiple admissions. Results Of 5062 patients enrolled in care, 877 (17.3 %) had 1137 admissions at median age 24 months (IQR: 12–62). 191 (21.8 %) patients had multiple admissions. A high proportion of admissions occurred in patients under two years (49.4 %), those within one month of clinic enrollment (32.9 %), those with severe immune suppression (44.0 %), and those not on ART (48.5 %). The frequency of primary admission diagnoses varied across these same variables, with malnutrition, pneumonia, and malaria being the most common. Conclusions Illness requiring hospitalization is common in HIV-infected and exposed children and these results reinforce the need for a comprehensive care package with special attention to nutrition. Strengthened programs for malaria prevention and expanded access to pneumococcal vaccine are also needed. The high burden of admissions in children under 24 months and those newly enrolled in care suggests a need for continued improvement of early infant diagnosis and provider-initiated testing programs to link patients to care before they are symptomatic. Similarly, the high proportion of admissions in those not yet started on ART emphasizes the importance of rapid initiation of ART for eligible pediatric patients.

Abstract
INTRODUCTION Paediatric antiretroviral therapy (ART) guidelines have been updated several times in recent years. We assessed implementation of ART guidelines among under-five children to inform the transition to universal paediatric ART in Tanzania. METHODS We conducted a retrospective cohort analysis of infants (0 to 11 months) and children (12 to 59 months) enrolled between 2010 and 2012 using routinely collected data. Infants and children were initiated on ART according to the 2008 World Health Organization (WHO) recommendations/2009 Tanzania guidelines (universal ART for infants). Cumulative ART initiation incidence and correlates of ART initiation were examined using competing risk methods accounting for attrition (death or loss to follow-up). Kaplan-Meier methods and Cox regression models were used to examine attrition on ART and its correlates. RESULTS A total of 1679 children were enrolled at 69 clinics: 469 (28%) infants and 1210 (74%) children. Infant cumulative ART initiation incidence was 59.6, 71.3 and 78.0% at one, three and six months of follow-up. Infants were more likely to start ART if enrolled in 2012 [adjusted sub-hazard ratio (AsHR)=2.2, 95% confidence interval (CI): 1.7 to 2.8] or 2011 (AsHR=1.8, 95% CI: 1.4 to 2.3) compared to 2010; they were more likely to start ART from prevention of mother-to-child HIV transmission (AsHR=1.6, 95% CI: 1.3 to 2.1) and inpatient wards (AsHR=1.5, 95% CI: 1.2 to 2.0) versus being enrolled from voluntary counselling and testing centres. Attrition at 12 months on ART was 33.9% and was more likely among infants with WHO Stage 4 [adjusted hazard ratio (AHR)=3.1. 95% CI: 1.8 to 5.2] and severe malnutrition (AHR=1.4, 95% CI: 1.0 to 1.9).Among 599 children eligible for ART at enrollment, cumulative ART initiation incidence was 51.8, 68.6 and 76.1% at one, three, and six months. Children were more likely to start ART if enrolled in 2012 (AsHR=1.8, 95% CI: 1.4 to 2.3) or 2011 (AsHR=1.5, 95% CI: 1.2 to 1.8) compared to 2010; they were more likely to start ART at primary health facilities (AsHR=1.5, 95% CI: 1.1 to 2.0) and less likely at urban facilities (AsHR=0.6, 95% CI: 0.5 to 0.9) and facilities without CD4 testing on site (AsHR=0.7, 95% CI: 0.5 to 0.9). Attrition at 12 months on ART was 23.1% and was more likely with severe malnutrition (AHR=1.8, 95% CI: 1.1 to 3.0), WHO Stage 4 (AHR=3.0, 95% CI: 1.0 to 8.5) and outpatient enrolees (AHR=1.7, 95% CI: 1.1 to 2.7). CONCLUSIONS Our findings suggest the gradual adoption of guidelines over calendar time. Interventions to expedite ART initiation and support retention on ART are needed.

Patching the gaps towards the 90-90-90 targets: outcomes of Nigerian children receiving antiretroviral treatment who are co-infected with tuberculosis. J Int AIDS Soc 2015; 18:20251. [PMID: 26639112 PMCID: PMC4670833 DOI: 10.7448/ias.18.7.20251] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2015] [Revised: 09/08/2015] [Accepted: 09/25/2015] [Indexed: 01/25/2023] Open
Abstract
INTRODUCTION Nigeria has a high burden of children living with HIV and tuberculosis (TB). This article examines the magnitude of TB among children receiving antiretroviral treatment (ART), compares their ART outcomes with their non-TB counterparts and argues that addressing TB among children on ART is critical for achieving the 90-90-90 targets. METHODS This was a facility-based, retrospective analysis of medical records of children aged <15 years who were newly initiated on ART between 2011 and 2012. Structured tools were used to collect data. STATA software was used to perform descriptive, survival and multivariate analyses. RESULTS A total of 1142 children with a median age of 3.5 years from 20 selected facilities were followed for 24 months. Of these, 95.8% were assessed for TB at ART initiation and 14.7% had TB. Children on ART were more likely to have TB if they were aged 5 years or older (p<0.01) and had delayed ART initiation (p<0.05). The cotrimoxazole and isoniazid prophylaxes were provided to 87.9 and 0.8% of children, respectively. The rate of new TB cases was 3 (2.2-4.0) per 100 person-years at six months and declined to 0.2 (0.06-1.4) per 100 person-years at 24 months. TB infection [adjusted hazard ratio (aHR): 4.3; 2.3-7.9], malnutrition (aHR: 5.1; 2.6-9.8), delayed ART initiation (aHR: 3.2; 1.5-6.7) and age less than 1 year at ART initiation (aHR: 4.0; 1.4-12.0) were associated with death. Additionally, patients with TB (aHR: 1.3; 1.1-1.6) and children below the age of 1 at ART initiation (aHR: 2.9; 1.7-5.2) were more likely to be lost to follow-up (LFU). CONCLUSIONS Children on ART with TB are less likely to survive and more likely to be LFU. These risks, along with low isoniazid uptake and delayed ART initiation, present a serious challenge to achieving the 90-90-90 targets and underscore an urgent need for inclusion of childhood TB/HIV in global plans and reporting mechanisms.

Abstract
Sub-Saharan Africa is home to millions of HIV-affected children. These children are likely to experience multiple developmental delays. In this chapter, I present data highlighting compromised neurobehavioral, mental health, and scholastic outcomes for children affected by HIV. Furthermore, I discuss biomedical factors (e.g., disease severity and nutritional status) that may exacerbate the adverse effects of HIV on childhood outcomes. I also present evidence on how psychosocial risk factors such as poor maternal mental health, orphanhood, and poverty may aggravate the effects of HIV. The concluding section of the chapter highlights conceptual and methodological refinements in research on the impact of HIV on child development in Sub-Saharan Africa.

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
Background To review the pediatric care and treatment program at Massey Street Children Hospital, in Lagos, Nigeria a retrospective analysis of medical records focusing on health services, survival and retention in care. Methods The analysis covered a cohort of children initiated on antiretroviral therapy (ART) from 2005 to 2011. In this population, pediatric HIV care was defined as initiating ART between ages 0 and 14 years. Treatment initiation and follow-up were according to the Nigerian national guidelines for pediatric ART, which are based on World Health Organization guidelines adapted to our local context. The primary endpoint was mortality measured as cumulative survival. Other outcomes of interest included “loss to follow-up”, “transferred out”, and “stopped treatment”. Results Mean (SD) age at ART initiation was 51 (39) months in female children and 52 (42) months in male children. After seven years of ART care, 64 % of the 660 study children were retained in care and on treatment, 16 % were lost to follow-up, 10 % were dead, and 9 % had discontinued HIV care at this facility for other reasons. World Health Organization disease stage, CD4 count, age, and year of ART initiation were highly predictive of mortality, while anemia at baseline was not statistically significantly associated. Conclusions Overall study results suggest a viable pediatric HIV program exists at the study facility. Retention rates were lowest for the earliest cohort of infected children, which implies long-term challenges. Mother-to-child transmission programs need to be dynamic to stem the scourge of pediatric HIV in Nigeria.
