INTRODUCTION: Adolescent and youth-friendly health services (AYFHS) have been promoted as a best practice for adolescents and young people living with HIV (AYLH). However, thorough descriptions of AYFHS for AYLH remain scarce. We sought to characterize adolescent-friendly HIV services in a global paediatric research consortium. METHODS: Cross-sectional data were collected from 16 global sites in the Adolescent and Young Adult Network of IeDEA (AYANI) of the International epidemiology Databases to Evaluate AIDS consortium between August 2020 and October 2022 using a standardized site assessment tool that collected data on clinic, patient and provider characteristics, differentiated care, and transition to adult services processes. Descriptive analyses characterized the health services available across the participating sites, using frequencies and proportions for categorical variables and medians and interquartile range for continuous variables. Data were analysed using RStudio. RESULTS: Overall, 13 of 16 sites (81%) reported having dedicated adolescent services, which most often consisted of dedicated clinic days (62%, n = 8/13), primarily offered on weekdays. Across all sites, nurses and counsellors delivered services to adolescents. Over half of all clinics (69%, n = 11/16) reported offering health education to adolescents to facilitate adolescent health literacy. Peer educators and navigators were involved in delivering services at 62% of sites, primarily in those with dedicated adolescent services (69%, n = 9/13). There was limited integration of sexual and reproductive health services into HIV clinics for adolescents. With 63% of clinics conducting pregnancy screening, 50% providing family planning methods and 38% providing cervical cancer screening. Under half of all HIV clinics screened for physical abuse or violence (44%, n = 7/16) and sexual abuse or rape (38%, n = 6/16). A low proportion of clinics screened for risk factors related to young key populations, including drug use (56%, n = 9/16), homelessness (38%, n = 6/16) young men having sex with men (31%, n = 5/16) and transactional sex (31%, n = 5/16). Mental health screening for concerns was variable. CONCLUSIONS: Findings suggest gaps in AYFHS for AYLH across the HIV clinics included in this analysis. There is a vital need to design health services for AYLH that are accessible, equitable, and effective and meet the global standards for delivering high-quality healthcare to adolescents.

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: 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: 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.
