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.
Global Trends in CD4 Measurement and Immunosuppression at ART Initiation Among Children With HIV.

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: 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 from September 2020 to 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 the inclusion criteria. Most (90%) reported screening for TB at HIV care enrollment. Access to diagnostics varied significantly by region, including nucleic acid amplification testing (NAAT, range 67-100%), mycobacterial culture (range 43%-83%), and drug susceptibility testing (range 30%-82%) (P < .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 = .008). TPT provision ranged 50%-100% (P < .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 may impede TB prevention, management, and successful outcomes for CLHIV, warranting continued close attention over time and as global TB care guidelines and services evolve.
