Introduction: African studies have reported high rates of loss to follow up (LTFU) among children in HIV care and treatment centres. Factors associated with LTFU may vary across populations. Few studies have been conducted among HIV infected children in care in rural areas of Kenya.

Background: Human immunodeficiency virus (HIV)-exposed uninfected (HEU) infants are a growing population in sub-Saharan Africa, with higher morbidity and mortality than HIV-unexposed infants. HEU infants may experience increased morbidity due to breastfeeding avoidance.

Objectives: We sought to describe the burden and identify predictors of hospitalization among HEU infants in the first year of life.

Background: A safe, effective vaccine for breastfeeding infants born to HIV-1-positive mothers could complement antiretroviral therapy (ART) for prevention of mother-to-child transmission of HIV-1. To date, only a few HIV-1 vaccine candidates have been tested in infants.

Trial Design: A phase I/II randomized controlled trial PedVacc 002 was conducted to determine the safety and immunogenicity of a single, low dose of MVA.

Maternal antiretroviral treatment (ART) is recommended for prevention of mother-to-child HIV-1 transmission (PMTCT), including in women with high CD4 cell counts. Within a pediatric HIV-1 vaccine trial PedVacc 002, we assessed hematologic profiles of infants born to mothers receiving ART. All mothers had CD4 cell counts of >350 mm; 93% received zidovudine-containing ART; infants received nevirapine up to 6 weeks and cotrimoxazole after 6 weeks.

Objective: To assess breastfeeding modes and determinants in a prevention of mother-to-child transmission study.

Design: HIV-1-infected pregnant women from 5 sites in Burkina Faso, Kenya, and South Africa were enrolled in the study that comprised 2 prospective cohorts and 1 randomized controlled trial. Women were counseled to either breastfeed exclusively up to 6 months or formula feed from birth.

Objectives: Early infant HIV-1 diagnosis and treatment substantially improve survival. Where virologic HIV-1 testing is unavailable, integrated management of childhood illness (IMCI) clinical algorithms may be used for infant HIV-1 screening. We evaluated the performance of the 2008 WHO IMCI HIV algorithm in a cohort of HIV-exposed Kenyan infants.

Purpose: To determine the prevalence and correlates of neonatal conjunctivitis in infants born to human immunodeficiency virus type 1 (HIV-1) infected mothers.

Methods: This was a nested case-control study within a perinatal HIV-1 cohort. HIV-1 seropositive mothers were enrolled during pregnancy and mother-infant pairs followed after delivery with assessment for neonatal conjunctivitis at 48 hours and up to 4 weeks after birth.

Objectives: To describe the early response to World Health Organization (WHO)-recommended nonnucleoside reverse transcriptase inhibitor (NNRTI)-based first-line highly active antiretroviral therapy (HAART) in HIV-1-infected Kenyan children unexposed to nevirapine.

Design: Observational prospective cohort.

Methods: HIV-1 RNA level, CD4 lymphocyte count, weight for age z score, and height for age z score were measured before the initiation of HAART and every 3 to 6 months thereafter.

Alpha-defensins are proteins exhibiting in vitro anti-HIV-1 activity that may protect against mother-to-child transmission of HIV-1 via breast milk. Correlates of alpha-defensins in breast milk and transmission risk were determined in a cohort of HIV-1-infected pregnant women in Nairobi followed for 12 months postpartum with their infants. Maternal blood was collected antenatally and at delivery for HIV-1 viral load and infant HIV-1 infection status was determined < 48 h after birth and at months 1, 3, 6, 9, and 12.

Objectives: The objectives of this study were to determine patterns of contraceptive utilization among sexually active HIV-1-seropositive women postpartum and to identify correlates of hormonal contraception uptake.

Goal: The goal of this study was to improve delivery of family planning services to HIV-1-infected women in resource-limited settings.

Study Design: HIV-1-infected pregnant women were followed prospectively in a perinatal HIV-1 transmission study.
