Objective: There is a growing body of data that demonstrates increased infectious disease outcomes for HIV-exposed uninfected (HIV-EU) infants as compared to their HIV-unexposed (HU) counterparts. We hypothesized that these HIV-EU infants are at greater risk for infectious morbidity and mortality when compared to the general childhood population. We therefore aimed to characterize infections and growth outcomes among HIV-EU infants in Jamaica during their first two years of life. By identifying these outcomes, specific interventions could be implemented to mitigate this risk of morbidity and mortality...

Longitudinal magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI) studies reveal significant changes in brain structure and structural networks that occur together with cognitive and behavioral maturation in childhood. However, the underlying cellular changes accompanying brain maturation are less understood. Examining regional age-related changes in metabolite levels provides insight into the physiology of neurodevelopment. Magnetic resonance spectroscopy (MRS) measures localize brain metabolism...

STRUCTURE: The study evaluated elvitegravir/cobicistat/tenofovir disoproxil fumarate (TDF)/emtricitabine (FTC) ("Quad pill") for postexposure prophylaxis (PEP). BACKGROUND: HIV-exposed individuals may benefit from PEP, but completion rates have been suboptimal because of regimen complexity and side effects. Newer antiretroviral combinations coformulated as single daily pills may optimize PEP adherence. SETTING: One hundred HIV-uninfected individuals who presented to a Boston community health center after an acute HIV sexual exposure were enrolled and initiated PEP with the daily, single-pill combination Quad pill for a 28-day course...

Increased morbidity and fetal growth restriction are reported in uninfected children born to HIV-1-infected women treated with antiretroviral (ARV) therapy. Viruses and/or pharmacological interventions such as ARVs can induce metabolic stress skewing the cell's immune response and restricting (cell) growth. Novel metabolomic techniques provided the opportunity to investigate the impact of fetal HIV-1 and combination ARV therapy (cART)-exposure on the infants' immune-metabolome. Peroxidized lipids, generated by reactive oxygen species, were increased in cART/HIV-1-exposed infants, indicating altered mitochondrial functioning...

Immunological and clinical findings suggestive of some immune dysfunction have been reported among HIV-exposed uninfected (HEU) children and adolescents. Whether these defects are persistent or transitory is still unknown. HEU pediatric population at birth, 12 months, 6-12 years were evaluated in comparison to healthy age-matched HIV-unexposed controls. Plasma levels of LPS, sCD14, cytokines, lymphocyte immunophenotyping and T-cell receptor excision circles (TREC) were assessed. HEU and controls had similar LPS levels, which remained low from birth to 6-12 years; for plasma sCD14, IL-2, IL-6, IL-7, IL-10, IL-12p70, IL-13, IL-17, IFN-γ, TNF-α, G-CSF, GM-CSF and MCP-1, which increased from birth to 12 months and then decreased at 6-12 years; and for TREC/106 PBMC at birth in HEU and controls...

Background: Pregnancy outcomes of perinatally HIV-infected women (PHIV) are poorly defined. Methods: We compared preterm delivery and birth weight (BW) outcomes [low BW (LBW, <2500 g), small-for-gestational-age (SGA), and BW z-scores (BWZ)] in HIV-exposed uninfected infants of PHIV vs. non-perinatally HIV-infected (NPHIV) pregnant women in the PHACS SMARTT or IMPAACT P1025 studies. Mixed effects models were fit to assess the association of maternal PHIV status with infant BWZ; log binomial models were used to estimate adjusted relative risks (aRR) for dichotomous outcomes...

HIV-1 infection causes AIDS, infecting millions worldwide. The virus can persist in a state of chronic infection due to its ability to become latent. We have previously shown a link between HIV-1 infection and exosome production. Specifically, we have reported that exosomes transport viral proteins and RNA from infected cells to neighboring uninfected cells. These viral products could then elicit an innate immune response, leading to activation of the Toll-like receptor and NF-κB pathways. In this study, we asked whether exosomes from uninfected cells could activate latent HIV-1 in infected cells...

Human immunodeficiency virus type 1 (HIV-1) infection is associated with B cell activation and exhaustion, and hypergammaglobulinemia. How these changes influence B cell responses to coinfections such as malaria is poorly understood. To address this, we compared B cell phenotypes and Abs specific for the Plasmodium falciparum vaccine candidate apical membrane Ag-1 (AMA1) in HIV-infected and uninfected adults living in Kenya. Surprisingly, HIV-1 infection was not associated with a difference in serum AMA1-specific Ab levels...

OBJECTIVES: HIV-exposed uninfected (HEU) infants have higher rates of severe and fatal infections compared with HIV-unexposed (HUU) infants, likely due to immune perturbations. We hypothesized that alterations in natural killer (NK) cell activity might occur in HEU infants and predispose them to severe infections. DESIGN: Case-control study using cryopreserved peripheral blood mononuclear cells (PBMCs) at birth and 6 months from HEU infants enrolled from 2002 to 2009 and HUU infants enrolled from 2011 to 2013...

Little is known about the neurodevelopmental outcomes of children older than 3 years of age born to HIV infected mother but who are HIV-uninfected (HEU), and who have been exposed in utero and early in life to HIV and to antiretroviral medications (ARVs). We conducted a longitudinal study of cognitive, visuomotor and adaptive function of HEU children, who were assessed at two ages, 3.5 and 5.5 years. Sixty-four children (33 female) were assessed. In comparison with population norms for their age, at 3.5 years of age they had scores significantly below age expectations on aspects of adaptive behavior, but at age 5...

BACKGROUND: Little is known regarding effects of perinatally acquired HIV infection (PHIV) on longitudinal change in memory and executive functioning (EF) during adolescence despite the importance of these skills for independence in adulthood. METHODS: PHIV (n = 144) and perinatally HIV-exposed uninfected youth (PHEU, n = 79), ages 12-17, completed standardized tests of memory and EF at baseline and 2 years later. Changes from baseline for each memory and EF outcome were compared between PHEU and PHIV youth with (PHIV/C, n = 39) and without (PHIV/non-C, n = 105) history of CDC class C (AIDS-defining) diagnoses...

Background: HIV-exposed infants are disproportionately at risk of morbidity and mortality compared with their HIV-unexposed counterparts. The role of co-trimoxazole preventive therapy (CPT) in reducing leading causes of infectious morbidity is unclear. Methods: We used data from the Breastfeeding, Antiretrovirals and Nutrition (BAN) clinical trial (conducted 2004-2010, Malawi) to assess the association of 1) CPT and 2) asymptomatic malaria parasitemia with respiratory and diarrheal morbidity in infants...

INTRODUCTION: HIV-exposed, uninfected (HEU) infants are potentially at risk for cardiovascular disease due to in utero exposures. Feeding practices of the infant could compound this risk. However, few studies have evaluated dietary intake of HEU infants. We determined dietary factors associated with rapid weight gain (RWG) among HEU infants from birth to 6 months followed at the University of Miami HIV Screening Program. METHODS: In this cross-sectional analysis, logistic regression was used to determine dietary factors associated with RWG defined as a greater than 0...
