Background

Initiation of antiretroviral therapy (ART) following diagnosis of HIV infection at birth is an emerging area of paediatric HIV care. We present outcomes of HIV-infected infants identified at birth at Rahima Moosa Mother and Child Hospital in Johannesburg, South Africa.

Methods

From September, 2013 (era 1), only high-risk HIV-exposed infants were offered diagnostic HIV PCR tests at birth. From June, 2014 (era 2), all HIV-exposed infants were offered laboratory-based diagnostic PCR tests. From October, 2014 (era 3), point of care (POC) diagnostic PCR tests were also done if staff availability allowed. We describe time to ART initiation, mortality, retention in care, and viral suppression among the HIV-infected infants identified across these eras.

Findings

We tested 5449 HIV-exposed infants who were born between Sept 1, 2013, and June 30, 2016. 88 neonates with confirmed HIV infection were identified and included in the study, of which 86 (98%) started ART. Median age at ART initiation decreased from 9 days (IQR 6–25) in eras 1 and 2 to 2 days (1–8) in era 3. In era 3, more neonates who were co-tested with POC testing started ART within 48 h of birth (29 [83%] of 35; median 1 day [IQR 1–2]) than infants who were not co-tested (one [4%] of 29; median 6 days [5–10]). The probability of mortality by 12 months across the eras was 14% (95% CI 8–24) and did not differ by era. Of the 72 infants who survived and initiated ART at the site, 56 (78%) were retained at 12 months. Of the 56 infants retained in care, 40 (71%) had a viral load less than 400 copies per mL at 12 months, with no differences between eras (p=0·23).

Interpretation

HIV-infected infants can be identified at birth and ART can be initiated within hours to days. Although most infants in our cohort started ART, mortality remained unacceptably high with suboptimal retention and viral suppression. Reducing mortality and improving retention and viral suppression remain urgent priorities.

Across sub-Saharan Africa, prevention of mother-to-child transmission services are encountering increasing numbers of women already established on antiretroviral therapy (ART) when entering antenatal care.

This study aimed to evaluate the impact of clinic-based prevention of mother-to-child transmission (PMTCT) community support by trained lay health workers in addition to standard clinical care on PMTCT infant outcomes.

Many countries are working to reduce or eliminate mother-to-child transmission (MTCT) of HIV. Prevention efforts have been conceptualized as steps in a cascade but cascade completion rates during and after pregnancy are low.

To understand the uptake of HIV services by adolescent women, the authors conducted a retrospective analysis of patient-level data (2011–2013) on services for antenatal care (ANC) and prevention of mother-to-child transmission (PMTCT) in 36 facilities in 5 districts in Zimbabwe.

An essential first step in caring for HIV-infected children is accurate and early diagnosis of HIV, early HIV testing, prompt return of results, and rapid initiation of treatment.

BACKGROUND:

The goal of virtual elimination of horizontal and mother-to-child HIV transmission in South Africa (SA) has been proposed, but there have been few systematic investigations of which interventions are likely to be most critical to reducing HIV incidence.

In 2013, Uganda updated its prevention of maternal-to-child transmission of HIV program to Option B+, which requires that all HIV-infected pregnant and breastfeeding women be started on lifelong antiretroviral therapy (ART) regardless of CD4 count…
