INTRODUCTION: Access to antiretroviral therapy (ART) is a global priority. However, the attrition across the continuum of care for HIV-infected children between their HIV diagnosis and ART initiation is not well known. We analyzed the time from enrollment into HIV care to ART initiation in HIV-infected children within the International Epidemiology Databases to Evaluate AIDS (IeDEA) Global Cohort Consortium. METHODS AND FINDINGS: We included 135,479 HIV-1-infected children, aged 0-19 years and ART-naïve at enrollment, between 1 January 2004 and 31 December 2015, in IeDEA cohorts from Central Africa (3 countries; n = 4,948), East Africa (3 countries; n = 22,827), West Africa (7 countries; n = 7,372), Southern Africa (6 countries; n = 93,799), Asia-Pacific (6 countries; n = 4,045), and Latin America (7 countries; n = 2,488). Follow-up in these cohorts is typically every 3-6 months. We described time to ART initiation and missed opportunities (death or loss to follow-up [LTFU]: last clinical visit >6 months) since baseline (the date of HIV diagnosis or, if unavailable, date of enrollment). Cumulative incidence functions (CIFs) for and determinants of ART initiation were computed, with death and LTFU as competing risks. Among the 135,479 children included, 99,404 (73.4%) initiated ART, 1.9% died, 1.4% were transferred out, and 20.4% were lost to follow-up before ART initiation. The 24-month CIF for ART initiation was 68.2% (95% CI: 67.9%-68.4%); it was lower in sub-Saharan Africa-ranging from 49.8% (95% CI: 48.4%-51.2%) in Central Africa to 72.5% (95% CI: 71.5%-73.5%) in West Africa-compared to Latin America (71.0%, 95% CI: 69.1%-72.7%) and the Asia-Pacific (78.3%, 95% CI: 76.9%-79.6%). Adolescents aged 15-19 years and infants <1 year had the lowest cumulative incidence of ART initiation compared to other ages: 62.2% (95% CI: 61.6%-62.8%) and 66.4% (95% CI: 65.7%-67.0%), respectively. Overall, 49.1% were ART-eligible per local guidelines at baseline, of whom 80.6% initiated ART. The following children had lower cumulative incidence of ART initiation: female children (p < 0.01); those aged <1 year, 2-4 years, 5-9 years, and 15-19 years (versus those aged 10-14 years, p < 0.01); those who became eligible during follow-up (versus eligible at enrollment, p < 0.01); and those receiving care in low-income or lower-middle-income countries (p < 0.01). The main limitations of our study include left truncation and survivor bias, caused by deaths of children prior to enrollment, and use of enrollment date as a proxy for missing data on date of HIV diagnosis, which could have led to underestimation of the time between HIV diagnosis and ART initiation. CONCLUSIONS: In this study, 68% of HIV-infected children initiated ART by 24 months. However, there was a substantial risk of LTFU before ART initiation, which may also represent undocumented mortality. In 2015, many obstacles to ART initiation remained, with substantial inequities. More effective and targeted interventions to improve access are needed to reach the target of treating 90% of HIV-infected children with ART.

INTRODUCTION: To eliminate cervical cancer (CC), access to and quality of prevention and care services must be monitored, particularly for women living with HIV (WLHIV). We assessed implementation practices in HIV clinics across sub-Saharan Africa (SSA) to identify gaps in the care cascade and used aggregated patient data to populate cascades for WLHIV attending HIV clinics. METHODS: Our facility-based survey was administered between November 2020 and July 2021 in 30 HIV clinics across SSA that participate in the International epidemiology Databases to Evaluate AIDS (IeDEA) consortium. We performed a qualitative site-level assessment of CC prevention and care services and analysed data from routine care of WLHIV in SSA. RESULTS: Human papillomavirus (HPV) vaccination was offered in 33% of sites. Referral for CC diagnosis (42%) and treatment (70%) was common, but not free at about 50% of sites. Most sites had electronic health information systems (90%), but data to inform indicators to monitor global targets for CC elimination in WLHIV were not routinely collected in these sites. Data were collected routinely in only 36% of sites that offered HPV vaccination, 33% of sites that offered cervical screening and 20% of sites that offered pre-cancer and CC treatment. CONCLUSIONS: Though CC prevention and care services have long been available in some HIV clinics across SSA, patient and programme monitoring need to be improved. Countries should consider leveraging their existing health information systems and use monitoring tools provided by the World Health Organization to improve CC prevention programmes and access, and to track their progress towards the goal of eliminating CC.

Eligibility for antiretroviral therapy is no longer based on immune criteria. In a global cohort of 97,453 children, between 2005 and 2021, we observed large declines in CD4 measurement, from 51% to 12% among <5 seconds, and from 74% to 20% among those 5-14 years of age. Lack of CD4 testing may negatively affect clinical care and surveillance of severe immune suppression.

BACKGROUND: In some time-to-event analyses, it is unclear whether loss to follow up should be treated as a censoring event or competing event. Such ambiguity is particularly common in HIV research that uses routinely collected clinical data to report the timing of key milestones along the HIV care continuum. In this setting, loss to follow up may be viewed as a censoring event, under the assumption that patients who are "lost" from a study clinic immediately enroll in care elsewhere, or a competing event, under the assumption that people "lost" are out of care all together. METHODS: We illustrate an approach to address this ambiguity when estimating the 2-year risk of antiretroviral treatment initiation among 19,506 people living with HIV who enrolled in the IeDEA Central Africa cohort between 2006 and 2017, along with published estimates from tracing studies in Africa. We also assessed the finite sample properties of the proposed approach using simulation experiments. RESULTS: The estimated 2-year risk of treatment initiation was 69% if patients were censored at loss to follow up or 59% if losses to follow up were treated as competing events. Using the proposed approach, we estimated that the 2-year risk of antiretroviral therapy initiation was 62% (95% confidence interval: 61, 62). The proposed approach had little bias and appropriate confidence interval coverage under scenarios examined in the simulation experiments. CONCLUSIONS: The proposed approach relaxes the assumptions inherent in treating loss to follow up as a censoring or competing event in clinical HIV cohort studies.

INTRODUCTION: Adolescents living with HIV are subject to multiple co-morbidities, including growth retardation and immunodeficiency. We describe growth and CD4 evolution during adolescence using data from the Collaborative Initiative for Paediatric HIV Education and Research (CIPHER) global project. METHODS: Data were collected between 1994 and 2015 from 11 CIPHER networks worldwide. Adolescents with perinatally acquired HIV infection (APH) who initiated antiretroviral therapy (ART) before age 10 years, with at least one height or CD4 count measurement while aged 10-17 years, were included. Growth was measured using height-for-age Z-scores (HAZ, stunting if <-2 SD, WHO growth charts). Linear mixed-effects models were used to study the evolution of each outcome between ages 10 and 17. For growth, sex-specific models with fractional polynomials were used to model non-linear relationships for age at ART initiation, HAZ at age 10 and time, defined as current age from 10 to 17 years of age. RESULTS: A total of 20,939 and 19,557 APH were included for the growth and CD4 analyses, respectively. Half were females, two-thirds lived in East and Southern Africa, and median age at ART initiation ranged from <3 years in North America and Europe to >7 years in sub-Saharan African regions. At age 10, stunting ranged from 6% in North America and Europe to 39% in the Asia-Pacific; 19% overall had CD4 counts <500 cells/mm CONCLUSIONS: Growth patterns during adolescence differed substantially by sex and region, while CD4 patterns were similar, with an observed CD4 decline that needs further investigation. Early diagnosis and timely initiation of treatment in early childhood to prevent growth retardation and immunodeficiency are critical to improving APH growth and CD4 outcomes by the time they reach adulthood.

INTRODUCTION: Stunting is a key issue for adolescents with perinatally acquired HIV (APH) that needs to be better understood. As part of the IeDEA multiregional consortium, we described growth evolution during adolescence for APH on antiretroviral therapy (ART). METHODS: We included data from sub-Saharan Africa, the Asia-Pacific, and the Caribbean, Central and South America regions collected between 2003 and 2016. Adolescents on ART, reporting perinatally acquired infection or entering HIV care before 10 years of age, with at least one height measurement between 10 and 16 years of age, and followed in care until at least 14 years of age were included. Characteristics at ART initiation and at 10 years of age were compared by sex. Correlates of growth defined by height-for-age z-scores (HAZ) between ages 10 and 19 years were studied separately for males and females, using linear mixed models. RESULTS: Overall, 8737 APH were included, with 46% from Southern Africa. Median age at ART initiation was 8.1 years (interquartile range (IQR) 6.1 to 9.6), 50% were females, and 41% were stunted (HAZ<-2 SD) at ART initiation. Males and females did not differ by age and stunting at ART initiation, CD4 count over time or retention in care. At 10 years of age, 34% of males were stunted versus 39% of females (p < 0.001). Females had better subsequent growth, resulting in a higher prevalence of stunting for males compared to females by age 15 (48% vs. 25%) and 18 years (31% vs. 15%). In linear mixed models, older age at ART initiation and low CD4 count were associated with poor growth over time (p < 0.001). Those stunted at 10 years of age or at ART initiation had the greatest growth improvement during adolescence. CONCLUSIONS: Prevalence of stunting is high among APH worldwide. Substantial sex-based differences in growth evolution during adolescence were observed in this global cohort, which were not explained by differences in age of access to HIV care, degree of immunosuppression or region. Other factors influencing growth differences in APH, such as differences in pubertal development, should be better documented, to guide further research and inform interventions to optimize growth and health outcomes among APH.

BACKGROUND: Co-trimoxazole is recommended for all children with human immunodeficiency virus. In this analysis, we evaluate trends in pediatric co-trimoxazole use and survival on co-trimoxazole in children using antiretroviral therapy (ART). METHODS: We used data collected between January 1, 2006, and March 31, 2016, from the International Epidemiology Databases to Evaluate AIDS. Logistic regression was used to evaluate factors associated with using co-trimoxazole at ART initiation. Competing risk regression was used to assess factors associated with death. RESULTS: A total of 54113 children were included in this study. The prevalence of co-trimoxazole use at ART initiation increased from 66.5% in 2006 to a peak of 85.6% in 2010 and then declined to 48.5% in 2015-2016. A similar trend was observed among children who started ART with severe immunodeficiency. After adjusting for year of ART initiation, younger age (odds ratio [OR], 1.18 for <1 vs 1 to <5 years of age [95% confidence interval (CI), 1.09-1.28]), lower height-for-age z score (OR, 1.15 for less than -3 vs greater than -2 [95% CI, 1.08-1.22]), anemia (OR, 1.08 [95% CI, 1.02-1.15]), severe immunodeficiency (OR, 1.25 [95% CI, 1.18-1.32]), and receiving care in East Africa (OR, 8.97 vs Southern Africa [95% CI, 8.17-9.85]) were associated with a high prevalence of co-trimoxazole use. Survival did not differ according to co-trimoxazole use in children without severe immunodeficiency (hazard ratio, 1.01 for nonusers versus users [95% CI, 0.77-1.34]). CONCLUSIONS: Recent declines in co-trimoxazole use may not be linked to the current shift toward early ART initiation. Randomized trial data might be needed to establish the survival benefit of co-trimoxazole in children without severe immunodeficiency.

BACKGROUND: Globally, the population of adolescents living with perinatally acquired HIV (APHs) continues to expand. In this study, we pooled data from observational pediatric HIV cohorts and cohort networks, allowing comparisons of adolescents with perinatally acquired HIV in "real-life" settings across multiple regions. We describe the geographic and temporal characteristics and mortality outcomes of APHs across multiple regions, including South America and the Caribbean, North America, Europe, sub-Saharan Africa, and South and Southeast Asia. METHODS AND FINDINGS: Through the Collaborative Initiative for Paediatric HIV Education and Research (CIPHER), individual retrospective longitudinal data from 12 cohort networks were pooled. All children infected with HIV who entered care before age 10 years, were not known to have horizontally acquired HIV, and were followed up beyond age 10 years were included in this analysis conducted from May 2016 to January 2017. Our primary analysis describes patient and treatment characteristics of APHs at key time points, including first HIV-associated clinic visit, antiretroviral therapy (ART) start, age 10 years, and last visit, and compares these characteristics by geographic region, country income group (CIG), and birth period. Our secondary analysis describes mortality, transfer out, and lost to follow-up (LTFU) as outcomes at age 15 years, using competing risk analysis. Among the 38,187 APHs included, 51% were female, 79% were from sub-Saharan Africa and 65% lived in low-income countries. APHs from 51 countries were included (Europe: 14 countries and 3,054 APHs; North America: 1 country and 1,032 APHs; South America and the Caribbean: 4 countries and 903 APHs; South and Southeast Asia: 7 countries and 2,902 APHs; sub-Saharan Africa, 25 countries and 30,296 APHs). Observation started as early as 1982 in Europe and 1996 in sub-Saharan Africa, and continued until at least 2014 in all regions. The median (interquartile range [IQR]) duration of adolescent follow-up was 3.1 (1.5-5.2) years for the total cohort and 6.4 (3.6-8.0) years in Europe, 3.7 (2.0-5.4) years in North America, 2.5 (1.2-4.4) years in South and Southeast Asia, 5.0 (2.7-7.5) years in South America and the Caribbean, and 2.1 (0.9-3.8) years in sub-Saharan Africa. Median (IQR) age at first visit differed substantially by region, ranging from 0.7 (0.3-2.1) years in North America to 7.1 (5.3-8.6) years in sub-Saharan Africa. The median age at ART start varied from 0.9 (0.4-2.6) years in North America to 7.9 (6.0-9.3) years in sub-Saharan Africa. The cumulative incidence estimates (95% confidence interval [CI]) at age 15 years for mortality, transfers out, and LTFU for all APHs were 2.6% (2.4%-2.8%), 15.6% (15.1%-16.0%), and 11.3% (10.9%-11.8%), respectively. Mortality was lowest in Europe (0.8% [0.5%-1.1%]) and highest in South America and the Caribbean (4.4% [3.1%-6.1%]). However, LTFU was lowest in South America and the Caribbean (4.8% [3.4%-6.7%]) and highest in sub-Saharan Africa (13.2% [12.6%-13.7%]). Study limitations include the high LTFU rate in sub-Saharan Africa, which could have affected the comparison of mortality across regions; inclusion of data only for APHs receiving ART from some countries; and unavailability of data from high-burden countries such as Nigeria. CONCLUSION: To our knowledge, our study represents the largest multiregional epidemiological analysis of APHs. Despite probable under-ascertained mortality, mortality in APHs remains substantially higher in sub-Saharan Africa, South and Southeast Asia, and South America and the Caribbean than in Europe. Collaborations such as CIPHER enable us to monitor current global temporal trends in outcomes over time to inform appropriate policy responses.

BACKGROUND: The COVID-19 pandemic challenged healthcare systems, particularly in settings with high infectious disease burden. We examined the postpandemic long-term impacts of COVID-19 on tuberculosis (TB) services at anti-retroviral therapy (ART) clinics in lower-income countries. METHODS: Using standardised online questionnaires, we conducted a cross-sectional site survey among ART clinics providing TB services in Africa and Asia from July to September 2023 (site-level information and number of TB diagnoses and tests). RESULTS: Of 45 participating ART clinics, 32 (71%) were in Africa and 13 (29%) in Asia. During the COVID-19 pandemic (2020-2022), 43 (96%) clinics reported implementing social distancing or separation measures, 39 (87%) personal protections for staff members and 32 (71%) protections for patients. Infection control measures were in place in 45% of the clinics before the pandemic (until 2019), 23% introduced measures during the pandemic and 15% maintained them after the pandemic (after 2022). Service provision was affected during the pandemic in 33 (73%) clinics, including TB services in 22 (49%) clinics. TB service restrictions were addressed by introducing changes in directly observed therapy provision in 8 (18%) clinics, multimonth TB drug dispensing in 23 (51%), telehealth services in 25 (56%) and differentiated service delivery in 19 (42%). These changes were sustained after the pandemic at 4 (9%), 11 (24%), 17 (38%) and 12 (27%) clinics, respectively. Compared with 2018-2019, the number of TB diagnoses decreased sharply in 2020-2021 and improved after the pandemic. CONCLUSIONS: COVID-19 affected TB care services in ART clinics in Africa and Asia. This was paralleled by a reduction in TB diagnoses, which partly resumed after the pandemic. Infection control measures and alternative modes of service delivery were adopted during the pandemic and only partially maintained. Efforts should be made to sustain the lessons learnt during the COVID-19 pandemic, particularly approaches that reduce the risk of transmission of infectious diseases, including TB, in ART clinics.

INTRODUCTION: Tuberculosis (TB) is a leading infectious cause of death globally. It is the most common opportunistic infection in people living with HIV, and the most common cause of their morbidity and mortality. Following TB treatment, surviving individuals may be at risk for post-TB lung disease. The TB Sentinel Research Network (TB-SRN) provides a platform for coordinated observational TB research within the International epidemiology Databases to Evaluate AIDS (IeDEA) consortium. METHODS AND ANALYSIS: This prospective, observational cohort study will assess treatment and post-treatment outcomes of pulmonary TB (microbiologically confirmed or clinically diagnosed) among 2600 people aged ≥15 years, with and without HIV coinfection, consecutively enrolled at 16 sites in 11 countries, across 6 of IeDEA's global regions. Data regarding clinical and sociodemographic factors, mental health, health-related quality of life, pulmonary function, and laboratory and radiographic findings will be collected using standardised questionnaires and data collection tools, beginning from the initiation of TB treatment and through 12 months after the end of treatment. Data will be aggregated for proposed analyses. ETHICS AND DISSEMINATION: Ethics approval was obtained at all implementing study sites, including the Vanderbilt University Medical Center Human Research Protections Programme. Participants will provide informed consent; for minors, this includes both adolescent assent and the consent of their parent or primary caregiver. Protections for vulnerable groups are included, in alignment with local standards and considerations at sites. Procedures for requesting use and analysis of TB-SRN data are publicly available. Findings from TB-SRN analyses will be shared with national TB programmes to inform TB programming and policy, and disseminated at regional and global conferences and other venues.

BACKGROUND: Tuberculosis (TB) remains a leading cause of morbidity and mortality for children living with HIV (CLHIV), with gaps in TB screening, diagnostics, management, and TB preventive therapy (TPT). We investigated reported practices in these domains at sites caring for CLHIV in low- and middle-income countries (LMICs) within the International epidemiology Databases to Evaluate AIDS (IeDEA) consortium. METHODS: We implemented a site survey during September 2020-February 2021, querying pre-pandemic practices. This analysis included sites in LMICs providing care for CLHIV that diagnosed TB in 2019. We analyzed responses using descriptive statistics and assessed regional differences using Fisher's exact or chi-square tests. RESULTS: Of 238 IeDEA sites, 227 (95%) responded and 135 met inclusion criteria. Most (90%) reported screening for TB at HIV care enrollment. Access to diagnostics varied significantly by region, including for nucleic acid amplification testing (NAAT, range 67-100%), mycobacterial culture (range 43-83%), and drug susceptibility testing (range 30-82%) (p<0.001). On-site TB treatment was high (90%). Reported stock-outs occurred for isoniazid (23/116, 20%) and other TB medications (11/114, 9.6%, range 0-33%, p=0.008). TPT provision ranged 50-100% (p<0.001). Six months of isoniazid was the most common TPT regimen for children (88%). Shorter TPT regimens were uncommon (0.9-2.8%), as were regimens for multidrug-resistant TB exposure (4.6%). CONCLUSIONS: Overall reported availability of NAAT and integrated TB/HIV treatment for CLHIV cared for at these IeDEA sites in LMICs is encouraging but varies by context. Heterogeneous implementation gaps remain-particularly for drug susceptibility testing, TPT delivery and TPT regimens-which successful outcomes for CLHIV, warranting continued close attention over time and as global TB care guidelines and services evolve.

BACKGROUND: The proportion of children living with HIV and receiving antiretroviral therapy (ART) in sub-Saharan Africa has increased greatly since 2006, yet the changes in their demographic characteristics and treatment outcomes have not been well described. We examine the trends in characteristics and outcomes of children living with HIV who were younger than 5 years at ART initiation, and compare outcomes over time and across country income groups. METHODS: We conducted a retrospective cohort analysis of data from children living with HIV who were younger than 5 years at ART initiation from 45 paediatric sites in 16 low-income, lower-middle-income, and upper-middle-income countries in sub-Saharan Africa (Benin, Burundi, Côte d'Ivoire, Democratic Republic of the Congo, Ghana, Kenya, Lesotho, Malawi, Mali, Mozambique, Rwanda, South Africa, Togo, Uganda, Zambia, and Zimbabwe). Outcomes were trends in patient characteristics at ART initiation (age, weight, height, and CD4%), and comparisons of mortality and loss to follow-up during ART over time and in various economic settings. We identified risk factors for mortality using Cox proportional hazards models. Each participating region had relevant institutional ethics review board approvals to contribute data to the analysis. FINDINGS: We included 32 221 children living with HIV and initiating ART younger than 5 years between Jan 1, 2006, and Dec 31, 2017. Median age at ART initiation was 20·4 months (IQR 9·4-36·0) in 2006-10, 19·2 months (8·3-33·6) in 2011-13, and 19·2 months (8·8-33·7) in 2014-17. Median age at ART initiation was 13·2 months (IQR 4·7-26·8) in upper-middle-income countries, 22·6 months (13·2-37·5) in lower-middle-income countries and 24·2 months (13·5-39·1) in low-income countries. The proportion of children initiating ART younger than 3 months increased from 770 (5·1%) of 14 943 children in 2006-10 to 728 (10·0%) of 7290 children in 2014-17. The proportion of children initiating ART with severe immunosuppression decreased from 5469 (74·7%) of 7314 children for whom CD4% data were available in 2006-10 to 2353 (55·2%) of 4269 children in 2014-17. Mortality at 24 months on ART decreased from 970 (6·5%) of 14 943 children in 2006-10 to 214 (2·9%) of 7290 children in 2014-17. Loss to follow-up was 20·5% (95% CI 20·1-21·0) overall, and was similar across time periods. In multivariable analysis, lower mortality was observed for more recent ART initiation cohorts (adjusted hazard ratio 0·70, 95% CI 0·63-0·79 for 2011-13; 0·53, 0·45-0·72 for 2014-17 vs 2006-10) and for those residing in an upper-middle-income country (0·42, 0·35-0·49 vs low-income countries). INTERPRETATION: Mortality declined significantly after universal ART recommendations for children younger than 2 years in 2010 and children younger than 5 years in 2013. However, substantial variations persisted across country income groups, and one in five children continue to be lost to follow-up. Targeted interventions are required to improve outcomes of children living with HIV, especially in the poorest countries. FUNDING: National Institute of Allergy and Infectious Disease.
