    (Wiley, 2025) Embleton, Lonnie; Sudjaritruk, Tavitiya; Machado, Daisy Maria; Chihota, Belinda; Musabyimana, Françoise; Jesson, Julie; Apondi, Edith; Puthanakit, Thanyawee; Luque, Marco Tulio; van Dongen, Nicola Ellen; Murenzi, Gad; Amorissani-Folquet, Madeleine; Kwena, Zachary; Perreras, Nicole; Rouzier, Vanessa; Lyamuya, Rita; Anderson, Kim; Elul, Batya; Leroy, Valériane; Enane, Leslie A.; Martin, Roxanne; Lancaster, Kathryn; Parcesepe, Angela M.; Vreeman, Rachel; Pediatrics, School of Medicine
    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.

    (Wiley, 2022) Collaborative Initiative for Paediatric HIV Education and Research (CIPHER) Global Cohort Collaboration; Jesson, Julie; Crichton, Siobhan; Quartagno, Matteo; Yotebieng, Marcel; Abrams, Elaine J.; Chokephaibulkit, Kulkanya; Le Coeur, Sophie; Aké-Assi, Marie-Hélène; Patel, Kunjal; Pinto, Jorge; Paul, Mary; Vreeman, Rachel; Davies, Mary-Ann; Ben-Farhat, Jihane; Van Dyke, Russell; Judd, Ali; Mofenson, Lynne; Vicari, Marissa; Seage, George, III.; Bekker, Linda-Gail; Essajee, Shaffiq; Gibb, Diana; Penazzato, Martina; Collins, Intira Jeannie; Wools-Kaloustian, Kara; Slogrove, Amy; Powis, Kate; Williams, Paige; Matshaba, Mogomotsi; Thahane, Lineo; Nyasulu, Phoebe; Lukhele, Bhekumusa; Mwita, Lumumba; Kekitiinwa-Rukyalekere, Adeodata; Wanless, Sebastian; Goetghebuer, Tessa; Thorne, Claire; Warszawski, Josiane; Galli, Luisa; van Rossum, Annemarie M.C.; Giaquinto, Carlo; Marczynska, Magdalena; Marques, Laura; Prata, Filipa; Ene, Luminita; Okhonskaya, Lyuba; Navarro, Marisa; Frick, Antoinette; Naver, Lars; Kahlert, Christian; Volokha, Alla; Chappell, Elizabeth; Pape, Jean William; Rouzier, Vanessa; Marcelin, Adias; Succi, Regina; Sohn, Annette H.; Kariminia, Azar; Edmonds, Andrew; Lelo, Patricia; Lyamuya, Rita; Ogalo, Edith Apondi; Odhiambo, Francesca Akoth; Haas, Andreas D.; Bolton, Carolyn; Muhairwe, Josephine; Tweya, Hannock; Sylla, Mariam; D'Almeida, Marceline; Renner, Lorna; Abzug, Mark J.; Oleske, James; Purswani, Murli; Teasdale, Chloe; Nuwagaba-Biribonwoha, Harriet; Goodall, Ruth; Leroy, Valériane; Medicine, School of Medicine
    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/mm3 . Across adolescence, higher HAZ was observed in females and among those in high-income countries. APH with stunting at age 10 and those with late ART initiation (after age 5) had the largest HAZ gains during adolescence, but these gains were insufficient to catch-up with non-stunted, early ART-treated adolescents. From age 10 to 16 years, mean CD4 counts declined from 768 to 607 cells/mm3 . This decline was observed across all regions, in males and females. 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.

    Incidence of switching to second-line antiretroviral therapy and associated factors in children with HIV: an international cohort collaboration
    (Elsevier, 2019-02) Collins, Intira J.; Wools-Kaloustian, Kara; Goodall, Ruth; Smith, Colette; Abrams, Elaine J.; Ben-Farhat, Jihane; Balkan, Suna; Davies, Mary-Ann; Edmonds, Andrew; Leroy, Valériane; Nuwagaba-Biribonwoha, Harriet; Patel, Kunjal; Paul, Mary E.; Pinto, Jorge; Conejo, Pablo Rojo; Sohn, Annette; Van Dyke, Russell; Vreeman, Rachel; Maxwell, Nicky; Timmerman, Venessa; Duff, Charlotte; Judd, Ali; Seage, George, III; Williams, Paige; Gibb, Diana M.; Bekker, Linda-Gail; Mofenson, Lynne; Vicari, Marissa; Essajee, Shaffiq; Mohapi, Edith Q.; Kazembe, Peter N.; Hlatshwayo, Makhosazana; Lumumba, Mwita; Kekitiinwa-Rukyalekere, Adeodata; Wanless, Sebastian; Matshaba, Mogomotsi S.; Goetghebuer, Tessa; Thorne, Claire; Warszawski, Josiane; Galli, Luisa; Geelen, Sybil; Giaquinto, Carlo; Marczynska, Magdalena; Marques, Laura; Prata, Filipa; Ene, Luminita; Okhonskaia, Liubov; Noguera-Julian, Antoni; Naver, Lars; Rudin, Christoph; Jourdain, Gonzague; Volokha, Alla; Rouzier, Vanessa; Succi, Regina; Chokephaibulkit, Kulkanya; Kariminia, Azar; Yotebieng, Marcel; Lelo, Patricia; Lyamuya, Rita; Marete, Irene; Oyaro, Patrick; Boulle, Andrew; Malisita, Kennedy; Fatti, Geoffrey; Haas, Andreas D.; Desmonde, Sophie; Dicko, Fatoumata; Abzug, Mark J.; Levin, Myron; Oleske, James; Chernoff, Miriam; Traite, Shirley; Purswani, Murli; Teasdale, Chloe; Chadwick, Ellen; Pediatrics, School of Medicine
    Background: Estimates of incidence of switching to second-line antiretroviral therapy (ART) among children with HIV are necessary to inform the need for paediatric second-line formulations. We aimed to quantify the cumulative incidence of switching to second-line ART among children in an international cohort collaboration. Methods: In this international cohort collaboration study, we pooled individual patient-level data for children younger than 18 years who initiated ART (two or more nucleoside reverse-transcriptase inhibitors [NRTI] plus a non-NRTI [NNRTI] or boosted protease inhibitor) between 1993 and 2015 from 12 observational cohort networks in the Collaborative Initiative for Paediatric HIV Education and Research (CIPHER) Global Cohort Collaboration. Patients who were reported to be horizontally infected with HIV and those who were enrolled in trials of treatment monitoring, switching, or interruption strategies were excluded. Switch to second-line ART was defined as change of one or more NRTI plus either change in drug class (NNRTI to protease inhibitor or vice versa) or protease inhibitor change, change from single to dual protease inhibitor, or addition of a new drug class. We used cumulative incidence curves to assess time to switching, and multivariable proportional hazards models to explore patient-level and cohort-level factors associated with switching, with death and loss to follow-up as competing risks. Findings: At the data cutoff of Sept 16, 2015, 182 747 children with HIV were included in the CIPHER dataset, of whom 93 351 were eligible, with 83 984 (90·0%) from sub-Saharan Africa. At ART initiation, the median patient age was 3·9 years (IQR 1·6-6·9) and 82 885 (88·8%) patients initiated NNRTI-based and 10 466 (11·2%) initiated protease inhibitor-based regimens. Median duration of follow-up after ART initiation was 26 months (IQR 9-52). 3883 (4·2%) patients switched to second-line ART after a median of 35 months (IQR 20-57) of ART. The cumulative incidence of switching at 3 years was 3·1% (95% CI 3·0-3·2), but this estimate varied widely depending on the cohort monitoring strategy, from 6·8% (6·5-7·2) in settings with routine monitoring of CD4 (CD4% or CD4 count) and viral load to 0·8% (0·6-1·0) in settings with clinical only monitoring. In multivariable analyses, patient-level factors associated with an increased likelihood of switching were male sex, older age at ART initiation, and initial NNRTI-based regimen (p<0·0001). Cohort-level factors that increased the likelihood of switching were higher-income country (p=0·0017) and routine or targeted monitoring of CD4 and viral load (p<0·0001), which was associated with a 166% increase in likelihood of switching compared with CD4 only monitoring (subdistributional hazard ratio 2·66, 95% CI 2·22-3·19). Interpretation: Our global paediatric analysis found wide variations in the incidence of switching to second-line ART across monitoring strategies. These findings suggest the scale-up of viral load monitoring would probably increase demand for paediatric second-line ART formulations.

    Outcomes After Second-Line Antiretroviral Therapy in Children Living with HIV in Latin America
    (Wolters Kluwer, 2021) Somerville, Kayla; Jenkins, Cathy A.; Carlucci, James G.; Person, Anna K.; Machado, Daisy Maria; Luque, Marco T.; Pinto, Jorge A.; Rouzier, Vanessa; Khalili Friedman, Ruth; McGowan, Catherine C.; Shepherd, Bryan E.; Rebeiro, Peter F.; Pediatrics, School of Medicine
    Background: Little is known about the long-term outcomes of children living with HIV in Latin America. Few studies have examined antiretroviral therapy (ART) regimen switches in the years after the introduction of ART in this population. This study aimed to assess clinical outcomes among children who started second-line ART in the Caribbean, Central and South America network for HIV epidemiology. Methods: Children (<18 years old) with HIV who switched to second-line ART at sites within Caribbean, Central and South America network for HIV epidemiology were included. The cumulative incidence and relative hazards of virologic failure while on second-line ART, loss to follow-up, additional major ART regimen changes, and all-cause mortality were evaluated using competing risks methods and Cox models. Results: A total of 672 children starting second-line ART were included. Three years after starting second-line ART, the cumulative incidence of death was 0.10 [95% confidence interval (CI) 0.08 to 0.13], loss to follow-up was 0.14 (95% CI: 0.11 to 0.17), and major regimen change was 0.19 (95% CI: 0.15 to 0.22). Of those changing regimens, 35% were due to failure and 11% due to toxicities/side effects. Among the 312 children with viral load data, the cumulative incidence of virologic failure at 3 years was 0.62 (95% CI: 0.56 to 0.68); time to virologic failure and regimen change were uncorrelated (rank correlation -0.001; 95% CI -0.18 to 0.17). Conclusions: Poor outcomes after starting second-line ART in Latin America were common. The high incidence of virologic failure and its poor correlation with changing regimens was particularly worrisome. Additional efforts are needed to ensure children receive optimal ART regimens.
