Background: Children living with HIV remain undiagnosed due to missed opportunities along the prevention of mother-to-child HIV transmission cascade. This study addresses programmatic gaps in the cascade by describing pregnancy and HIV-related services received by mothers of children newly identified as HIV-positive through active case finding. Methods: This was a prospective observational cohort (2017–2018) of HIV-positive children <15 years of age newly diagnosed at study facilities and/or surrounding communities in Kenya and Uganda. At enrollment, caregivers were interviewed about maternal and child health and HIV history. Child medical and laboratory information was abstracted at two months post-diagnosis. Descriptive summary statistics were calculated; associations between selected factors and child age at HIV diagnosis were evaluated using generalized estimating equations. Results: 174 HIV-positive children (median age 2.4 years) were enrolled. Among maternal caregivers, 110/132 (83.3%) attended antenatal care and 60 (45.5%) reported testing HIV-negative in antenatal care. Of 41 and 56 women known to be HIV-positive during pregnancy and breastfeeding respectively, 17 (41.5%) and 15 (26.8%) did not receive antiretroviral drugs. Despite known maternal HIV-positive status during pregnancy, 39% of these children were not diagnosed until after two years of age; children were diagnosed at younger ages in Uganda (p = 0.0074) and if mother was the caregiver (p<0.0001). The most common HIV testing points identifying children were outpatient (44.3%) and maternal/child health departments (29.9%). Nearly all children initiated antiretroviral therapy within two weeks of diagnosis. Conclusions: Multiple missed opportunities for HIV prevention and delays in HIV testing of HIV-exposed children were identified in newly diagnosed children. Findings support critical prevention messaging and retesting of HIV-negative women during pregnancy and breastfeeding, strengthening HIV treatment initiation and follow-up systems and interventions to ensure HIV-positive women receive lifelong antiretroviral therapy throughout the cascade, and broader implementation of community case finding so children not engaged in care receive testing services.

Objective: Prevention of Mother-to-Child Transmission of HIV programs require follow-up of HIV-exposed infants (HEI) for infant feeding support, prophylactic medicines, and HIV diagnosis for at least 18 months. Retention in care and receipt of HIV services are challenging in resource-limited settings. This study compared infant follow-up results when HEI services were provided within Maternal and Child Health (MCH) clinics or in specialized HIV Comprehensive Care Clinics (CCCs) in Kenya., Methods: This observational prospective cohort study enrolled HEI at 6-8 weeks of age in 2 purposively selected hospitals with similar characteristics but different models of service delivery. In the CCC model, HEI received immunization and growth monitoring in MCH but cotrimoxazole prophylaxis and infant HIV testing in the CCC. In the MCH model, all services were provided in the MCH. Data were collected at enrollment, 14 weeks, and 6, 9, and 12 months., Results: From April 2008 to April 2009, 184 HEI were enrolled in the CCC cohort and 179 in the MCH cohort. Infants in MCH were 1.14, 1.42, 1.95, and 1.29 times more likely to attend 14-week, 6-, 9-, and 12-month postnatal visits, respectively, and 2.24 times (95% confidence interval: 1.57 to 3.18) more likely to attend all 4 visits. Although infants in MCH were 1.33 times (95% confidence interval: 1.10 to 1.62) more likely to have HIV antibody testing at 1 year than CCC, there were no differences for polymerase chain reaction test or cotrimoxazole initiation at 6-8 weeks., Conclusions: HIV services integrated in MCH yield better follow-up of HEI than CCC.
