OBJECTIVES: To compare neurodevelopmental outcomes of HIV-exposed uninfected (HEU) and HIV-unexposed uninfected (HUU) infants in a peri-urban South African population. HEU infants living in Africa face unique biological and environmental risks but uncertainty remains regarding their neurodevelopmen-tal outcome. This is partly due to lack of well-matched HUU comparison groups needed to adjust for confounding factors. METHODS: This was a prospective cohort study of infants enrolled at birth from a low- risk midwife obstetric facility...

Health worker experience and community support may be higher in high HIV prevalence regions than low prevalence regions, leading to improved prevention of mother-to-child HIV transmission (PMTCT) programs. We evaluated 6-week and 9-month infant HIV transmission risk (TR) in a high prevalence region and nationally. Population-proportionate-to-size sampling was used to select 141 clinics in Kenya, and mobile teams surveyed mother-infant pairs attending 6-week and 9-month immunizations. HIV DNA testing was performed on HIV-exposed infants...

INTRODUCTION: Despite declining risk of vertical HIV transmission, prophylactic cotrimoxazole (CTX) remains widely used to reduce morbidity and mortality in the event of HIV infection among exposed infants, with an inherent risk of conferring commensal antimicrobial resistance. Using data from a randomized, placebo-controlled trial of infant CTX prophylaxis, we sought to quantify emergence of antibiotic resistance. METHODS: HIV-exposed uninfected infants enrolled in the Botswana Mpepu study were randomized to prophylactic CTX or placebo between 14 and 34 days of life and continued through 15 months...

BACKGROUND: A previous review of early infant diagnosis (EID) using polymerase chain reaction technology (PCR) under integrated HIV care (IHC) program in Myanmar revealed a low uptake of timely (within 6 to 8 weeks of babies' age) EID and a long turnaround time (TAT) of receiving results. OBJECTIVE: This study aimed to determine the proportion and factors associated with the composite outcome of a long TAT (≥7 weeks; from sample collection to receipt of result by mother) or nonreceipt of result among HIV-exposed babies whose blood samples were collected for PCR at <9 months of age under the IHC program, Myanmar (2013-15)...

Polymorphisms in the Toll-Like Receptor (TLR9) 1635 locus have been associated with HIV-1 acquisition and progression. Cytomegalovirus (CMV) and Epstein-Barr virus (EBV) acquisition were compared between Kenyan HIV-exposed infants by 1635 genotype. Having 1 or more copies of the 1635A allele was associated with increased CMV acquisition in HIV-infected infants (42% vs 11%, p = 0.03) and increased risk of EBV acquisition in HIV-exposed uninfected infants (HR = 4.2, p = 0.02) compared to 1635GG. Additionally, 1635A was associated with 0...

Vitiligo is a dermatological disease; its exact prevalence is unknown among the paediatric population. We are reporting a case of vitiligo at birth for the first time in Burkina Faso, in the Teaching Hospital Souro Sanou of Bobo-Dioulasso, Paediatric Department. He is a male child, born from HIV-1 positive parents; we received him when he was 2 months to be followed in connection with the prevention of motherto-child transmission. He showed achromic lesions on the skin and on skin appendages at birth. In addition to congenital vitiligo we mentioned, several diagnostic hypotheses were discussed...

A significant number of infants acquire HIV-1 through their infected mother's breast milk, primarily due to limited access to antiretrovirals. Passive immunization with neutralizing antibodies (nAbs) may prevent this transmission. Previous studies, however, have generated conflicting results about the ability of nAbs to halt mother-to-child transmission (MTCT) and their impact on infant outcomes. This study compared plasma neutralizing activity in exposed infants and the infected mothers (n = 63) against heterologous HIV-1 variants and the quasispecies present in the mother...

BACKGROUND: Despite the recognized benefit of antiretroviral therapy (ART) for preventing and treating HIV, some studies have reported adverse birth outcomes with in utero ART exposure. We evaluated the effect of infant in utero HIV and ART exposure on preterm delivery (PTD), low birth weight (LBW), small for gestational age (SGA), and underweight for age (UFA) at 6 weeks. METHODS: We surveyed 6179 HIV-unexposed-uninfected (HUU) and 2599 HIV-exposed-uninfected (HEU) infants...

Antiretroviral drugs are used in neonates for prevention and treatment of HIV infection. Use of antiretrovirals to prevent perinatal HIV transmission is well established. Early identification of neonates infected with HIV and rapid initiation of combination antiretroviral treatment during the neonatal period is now recommended by WHO and DHHS. However, few antiretrovirals are available in formulations suitable for neonates and there are limited safety and pharmacokinetic data for most antiretrovirals in neonates...

Background: Vaccination of HIV-infected infants with bacille Calmette-Guérin (BCG) is contraindicated. HIV-exposed newborns need a new tuberculosis (TB) vaccination strategy that protects against TB early in life; and avoids the potential risk of BCG disease until after HIV infection has been excluded. Methods: This double-blind randomized controlled trial compared newborn MVA85A prime vaccination (1 x10 8 PFU) vs. Candin® control, followed by selective deferred BCG vaccination at 8 weeks of age for HIV-uninfected infants, and 12 months follow-up for safety and immunogenicity...

In the RV144 vaccine trial, IgG responses against the HIV envelope variable loops 1 and 2 (V1V2) were associated with decreased HIV acquisition risk. We previously reported that infants immunized with a MF59 adjuvanted rgp120 vaccine developed higher magnitude anti-V1V2 IgG responses than adult RV144 vaccinees. To determine if the robust antibody response in infants is due to differences in vaccine regimens or to inherent differences between the adult and infant immune systems, we compared Env-specific IgG responses in adults and infants immunized with the same MF59 and Alum adjuvanted HIV envelope vaccines...

Background: Prevention of mother-to-child transmission (PMTCT) of HIV programs have been scaled-up in many low- and middle-income countries; however, HIV drug resistance (HIVDR) data amongst HIV-1-infected young children remain limited. Methods: Surveys of pre-treatment HIVDR amongst children younger than 18 months of age who were diagnosed with HIV through Early Infant Diagnosis were conducted in five sub-Saharan African countries (Mozambique, Swaziland, South Africa, Uganda, and Zimbabwe) between 2011 and 2014 following World Health Organization guidance...

INTRODUCTION: Early infant diagnosis is an important step in identifying children infected with HIV during the perinatal period or in utero. Multiple factors contribute to delayed antiretroviral treatment initiation for HIV-infected children, including delays in the early infant HIV diagnosis cascade. METHODS: We conducted a retrospective study to evaluate early infant diagnosis turnaround times in Lesotho. Trained staff reviewed records of HIV-exposed infants (aged-6-8 weeks) who received an HIV test during 2011...

HIV-exposed infants born to depressed women may be at risk for adverse developmental outcomes. Half of HIV-infected women in rural South Africa (SA) may suffer from pregnancy-related depression. This pilot study examined the impact of depression in HIV-infected women in rural SA on infant development. Mother-infant dyads (N = 69) were recruited in rural SA. Demographics, HIV disclosure, depression, male involvement, and alcohol use at baseline (18.35 ± 5.47 weeks gestation) were assessed. Male involvement, depression, infant HIV serostatus and development were assessed 12 months postnatally...

Women's empowerment is associated with engagement in some areas of healthcare, but its role in prevention of mother-to-child HIV transmission (PMTCT) services has not been previously considered. In this secondary analysis, we investigated the association of women's decision-making and uptake of health services for PMTCT. Using data from population-based household surveys, we included women who reported delivery in the 2-year period prior to the survey and were HIV-infected. We measured a woman's self-reported role in decision-making in her own healthcare, making of large purchases, schooling of children, and healthcare for children...

Combination antiretroviral regimens have achieved tremendous success in reducing perinatal HIV transmission, and have become standard of care in pregnant women with HIV. However, the large variety of combination antiretroviral regimens utilized in practice raises the question of whether some of these highly potent drugs pose other risks to the pregnancy or infant. While HIV-infected pregnant women are almost always exposed to multiple antiretrovirals concurrently, standard safety screening strategies typically consider each individual antiretroviral separately, which fails to account for potential confounding due to simultaneous exposure to other antiretrovirals...
