BACKGROUND: Growth failure is common among HIV-infected infants, but there are limited data on the effects of HIV exposure or timing of HIV acquisition on growth. METHODS: 14110 infants were enrolled in the ZVITAMBO trial in Zimbabwe before the availability of antiretroviral therapy (ART) or co-trimoxazole. Anthropometric measurements were taken from birth through 12-24 months of age. Growth outcomes were compared between 5 groups of children: HIV-infected in utero (IU), intrapartum (IP) or postnatally (PN); HIV-exposed uninfected (HEU); and HIV-unexposed...

Despite the availability of efficacious prevention of mother-to-child transmission (PMTCT) interventions and improved access to preventive services in many developing countries, vertical HIV transmission persists. A matched case-control study of HIV-exposed infants between January and June 2012 was conducted at 20 clinics in Kenya. Cases were HIV-infected infants and controls were exposed, uninfected infants. Conditional logistic regression analysis was conducted to determine characteristics associated with HIV infection...

INTRODUCTION: The impact of HIV infection and antiretroviral therapy (ART) on neurocognitive outcomes among children aged 7 to 14 years was assessed. We hypothesized that ART would ameliorate neurocognitive sequelae of HIV infection. METHODS: HIV-positive and negative mother-child pairs from the Rakai Community Cohort Study (RCCS) and ART clinics in Rakai, Uganda were followed prospectively over 4 years. Exposures were stratified as: Perinatally HIV Infected (PHIV), Perinatally HIV Exposed but Uninfected (PHEU), and HIV Unexposed and Uninfected (HUU)...

BACKGROUND: Antiretroviral therapy (ART) in HIV pregnant women has led to a dramatic decrease in the rate of HIV mother-to-child transmission but this benefit is counterbalanced with adverse effects related to in utero and neonatal exposure to ART. In 2013, some parents described neurodevelopmental disorders in their children. METHODS: A standardized letter was sent to the 133 women who delivered in Nantes hospital from 01/01/2003 to 31/12/2012 (167 births). RESULTS: Response rate was 33%...

BACKGROUND: The 13-valent pneumococcal conjugate vaccine (PCV13) was designed to include disease-causing serotypes that are important in low-income and middle-income countries. Vaccine effectiveness estimates are scarce in these settings. South Africa replaced PCV7 with PCV13 in 2011 using a 2 + 1 schedule. We aimed to assess the effectiveness of two or more doses of PCV13 against invasive pneumococcal disease in children with HIV infection and in those not infected with HIV. METHODS: Cases of invasive pneumococcal disease in children aged 5 years or younger were identified through national laboratory-based surveillance...

BACKGROUND: Early feeding patterns may affect the growth of HIV-exposed children and thus their subsequent health and cognition. OBJECTIVE: We assessed the association of infant feeding (IF) mode with length-for-age z score (LAZ) and stunting from age 2 d to 18 mo in HIV-exposed African children within a controlled randomized trial, which evaluated triple antiretrovirals initiated during pregnancy and continued for 6 mo postpartum to prevent HIV transmission. METHODS: HIV-infected pregnant women with CD4(+) counts of 200-500 cells/mm(3) from Burkina Faso, Kenya, and South Africa were advised to exclusively breastfeed for up to 6 mo or to formula-feed from birth...

Cigarette smoke usage is prevalent in HIV+ patients and, despite highly active antiretroviral therapy (HAART), these individuals develop an accelerated form of chronic obstructive pulmonary disease (COPD). Studies investigating the mechanisms of COPD development in HIV have been limited by the lack of suitable mouse models. Here we describe a model of HIV induced COPD in wild type mice using EcoHIV, a chimeric HIV capable of establishing chronic infection in immunocompetent mice. A/J mice were infected with EcoHIV and subjected to whole body cigarette smoke exposure...

BACKGROUND: Much evidence of HIV-exposed uninfected (HEU) infant infectious morbidity predates availability of maternal combination antiretroviral therapy and does not control for universal risk factors (preterm birth, low birth weight, suboptimal breastfeeding and poverty). METHODS: This prospective cohort study identified HIV-infected and HIV-uninfected mothers and their newborns from South African community midwife unit. The primary outcome, infectious cause hospitalization or death before 6 months of age, was compared between HEU and HIV-unexposed (HU) infants and classified for type and severity using validated study-specific case definitions...

Trimethoprim-sulfamethoxazole (TMP-SMX) is widely used in malaria-endemic areas in human immunodeficiency virus (HIV)-infected children and HIV-uninfected, HIV-exposed children as opportunistic infection prophylaxis. Despite the known effects that TMP-SMX has in reducing clinical malaria, its impact on development of malaria-specific immunity in these children remains poorly understood. Using rodent malaria models, we previously showed that TMP-SMX, at prophylactic doses, can arrest liver stage development of malaria parasites and speculated that TMP-SMX prophylaxis during repeated malaria exposures would induce protective long-lived sterile immunity targeting pre-erythrocytic stage parasites in mice...

OBJECTIVE: HIV-exposed uninfected infants (HEUs) have frequent severe infection, hospitalization and death. We performed a serologic investigation to determine the role of common childhood respiratory pathogens in the excess incidence of infections in HEUs. DESIGN: Prospective cohort study of mother-infant pairs. METHODS: Among 247 HEUs and 88 HIV-unexposed uninfected (HUU) infant-mother pairs, we measured maternal antibodies to respiratory syncytial virus (RSV) and pneumococcus (PNC 1, 5, 6B, 14); infant antibodies to RSV, influenza A (Flu), parainfluenza viruses (PIV 1, 2, 3), and PNC 1, 5, 6B and 14 were measured at 0 and 6 months, and anti-tetanus antibodies at 6 months...

Cytomegalovirus acquisition and inflammation were evaluated in 231 HIV-exposed uninfected (HEU) and 100 HIV-unexposed Zimbabwean infants at age 6 weeks. HEU and HIV-unexposed infants had a similarly high prevalence of CMV (81.4% vs. 74.0%, respectively; P=0.14), but HEU infants had higher CMV viral loads (P=0.005) and >2-fold higher CRP concentrations (P<0.0001). CMV-positive HEU infants had higher CRP than CMV-negative HEU infants; this association disappeared after adjusting for maternal HIV viral load...

The World Health Organization AIDS epidemic update estimates that more than 37 million people are living with HIV infection. Despite the unprecedented success of antiretroviral treatments, significant challenges remain in the fight against HIV. In particular, how uninfected cells capture HIV and transmit virions to target cells remains an unanswered question. Tissue mast cells and peripheral blood basophils can be exposed to virions or HIV products during infection. Several HIV proteins (i.e., envelope glycoproteins gp120 and gp41, Tat, and Nef) can interact with distinct surface receptors expressed by human basophils and mast cells and modulate their functional responses at different levels...

We evaluated the effect of maternal HIV infection on trans-placental antibody transfer specific to eight group B Streptococcus (GBS) surface protein among 81 HIV-uninfected and 83 HIV-infected mother-newborn pairs using a multiplex immunoassay. Significantly lower antibody titres were detected in HIV-infected mothers and HIV-exposed uninfected newborns compared to HIV-uninfected mother-newborn dyads. Maternal HIV infection was also associated with reduced trans-placental transfer of antibodies for Sip (25.8%), Foldase (30...

Group B Streptococcus (GBS) is a major cause of neonatal sepsis and mortality worldwide. Studies from both developed and developing countries have shown that HIV-exposed but uninfected (HEU) infants are at increased risk of infectious morbidity, as compared to HIV-unexposed uninfected infants (HUU). A higher susceptibility to GBS infections has been reported in HEU infants, particularly late-onset diseases and more severe manifestations of GBS diseases. We review here the possible explanations for increased susceptibility to GBS infection...

OBJECTIVE: Tenofovir (TDF) affects bone health and is widely used in pregnancy but data are limited on the effects of TDF exposure in utero. We examined the association between duration of in-utero TDF exposure and linear growth in HIV-exposed, uninfected (HEU) infants. DESIGN: A prospective cohort of pregnant women initiating TDF-containing regimens at primary care services in Cape Town, South Africa, were enrolled and followed with their breastfeeding infants through 12 months postpartum...

Here we determined the relative expression of HERV-K and W proviruses in HIV infected and non-infected mothers as well as their respective babies up to 1 year-old. HIV-infected mothers, their babies and uninfected control groups presented expression of both HERV-K and HERV-W with relatively high frequency. While the level of HERV-K expression was similar among groups, the level of HERV-W expression in HIV-infected mothers was four-fold higher than the uninfected mothers from the control group (p < 0.01)...

Increased disease susceptibility during early life has been linked to immune immaturity, regulatory T-cell/TH2 immune biasing and hyporesponsiveness. The contribution of myeloid derived suppressor cells (MDSCs) remains uninvestigated. Here, we assessed peripheral MDSC in HIV-infected and -uninfected children with tuberculosis (TB) disease before, during and after TB treatment, along with matched household contacts (HHCs), HIV-exposed, -infected and -uninfected children without recent TB exposure. Serum analytes and enzymes associated with MDSC accumulation/activation/function were measured by colorimetric- and fluorescence arrays...
