Follow-Up Outcomes of Children, Adolescents, and Young People on Darunavir-Based Third-Line Antiretroviral Therapy: Observational Cohort From 9 African Countries.

BACKGROUND: We assessed clinical outcomes among children, adolescents, and people younger than 25 years on darunavir-based antiretroviral therapy (ART) in 9 sub-Saharan African countries. SETTING: Third-line ART centers in Cameroon, Eswatini, Kenya, Lesotho, Nigeria, Rwanda, Uganda, Zambia, and Zimbabwe. METHODS: From January 2019 to December 2022, we collected data from a cohort of children, adolescents, and young people receiving third-line ART from 9 sub-Saharan African countries. Data on treatment continuity, viral suppression, death, and clinic transfers were extracted from medical records and summarized. Cox proportional hazards models were used to identify factors independently associated with retention in care. RESULTS: Of 871 participants enrolled, the median age was 14.8 (range: 0.2-24.7) years and 488 (56.0%) were male; 809 (92.9%) [median duration of follow-up of 28.3 months (interquartile range: 17.5-45.2)] had final outcomes after initiating third-line ART. Of these, 711 (87.9%) were alive and in care at the end of study follow-up, 29 (3.6%) died, 30 (3.7%) were transferred to other facilities, and 39 (4.8%) were lost to follow-up. Retention in care was less likely among male patients compared with female patients [aHR: 0.85, 95% confidence interval: 0.72 to 1.0] and in 10-14-year-old children compared with younger children. Adolescents (15-19 years old) had higher mortality compared with children younger than 10 years (aSHR: 4.20, 95% confidence interval: 1.37 to 12.87). Viral suppression was seen in 345/433 (79.7%), 249/320 (77.8%), and 546/674 (81.0%) patients with results at 6 months, 12 months, and study end, respectively. CONCLUSIONS: A high proportion of children and young people receiving third-line ART in sub-Saharan Africa remain in care and attain viral suppression during follow-up.

Implementation and Uptake of Raltegravir Granules in Newborns Diagnosed With HIV Through Birth Testing in Maternity Settings in Zimbabwe During the COVID-19 Pandemic.

Zimbabwe introduced raltegravir (RAL) granules at 14 facilities providing point-of-care HIV birth testing, aiming to initiate all newborns with HIV on a RAL-based regimen. From June 2020 to July 2021, we tested 3172 of the 6989 (45%) newborns exposed to HIV; we diagnosed 59(2%) with HIV infection, of whom 27 (46%) initiated RAL. The SARS-CoV-2 coronavirus disease pandemic exacerbated supply chain and trained provider shortages, contributing to low birth testing, RAL uptake and 6-month viral load testing.

Optimising neonatal antiretroviral therapy using raltegravir: a qualitative analysis of healthcare workers' and caregivers' perspectives.

BACKGROUND: In 2020, Zimbabwe adopted the WHO's recommendation to use raltegravir (RAL) granule-based regimens for treatment of neonates identified with HIV at the time of birth testing. This study explores the acceptability of RAL granules by caregivers and healthcare workers (HCWs). METHODS: Interviews were conducted with 15 caregivers and 12 HCWs from 8 health facilities in Zimbabwe participating in the introductory pilot of RAL granules treatment for newborns. Eligible caregivers included those who had administered RAL to their infant and attended either 8th or 28th day of life appointments. Caregivers of neonates recently initiated on RAL were selected through convenience sampling. Eligible HCWs who provided RAL preparation, administration instructions and support to caregivers of neonates on RAL for at least 3 months were recruited from the same facilities as the caregivers. Interview transcripts were coded and thematically analysed. RESULTS: Caregivers reported that their babies looked healthier after RAL initiation, with improved skin appearance and weight gain. Some caregivers wanted their child to remain on RAL beyond 28 days instead of switching regimens, as recommended by national guidelines. HCWs observed that RAL granules improved health outcomes compared with other regimens. HCWs reported challenges with caregivers understanding dosing instructions, measuring with a syringe, swirling and not shaking the medicine, discarding unused medication and following the changes in the dosing schedule and amount when RAL was initiated a few days after birth. HCWs stated that adequate counselling and repeat demonstrations were crucial to ensure that caregivers clearly understood RAL dosing and administration instructions. HCWs requested more standardised training targeting nurses with guidance on handling missed doses and clarification on mixing RAL granules with water and not breastmilk. CONCLUSION: While feedback from caregivers and HCWs on RAL implementation was positive, barriers were also noted. Adequate training and sufficient instruction and support for caregivers would help to ensure that RAL granules are prepared, dosed and administered correctly.
