OBJECTIVE: Sub-Saharan Africa has the highest prevalence of children at risk of not achieving their developmental potential, attributable largely to the human immunodeficiency virus (HIV) pandemic coupled with negative environmental factors. Childhood developmental stimulation programmes can mitigate adverse outcomes. METHODS: Neonates testing HIV positive at birth will be initiated on antiretroviral treatment (ART) and receive an age-appropriate stimulation program, updated at 3 monthly intervals through the first year of life...

The conformation of the HIV-1 envelope glycoprotein (Env) substantially impacts antibody recognition and antibody-dependent cellular cytotoxicity (ADCC) responses. In the absence of the CD4 receptor at the cell surface, primary Envs sample a "closed" conformation that occludes CD4-induced (CD4i) epitopes. The virus controls CD4 expression through the actions of Nef and Vpu accessory proteins, thus protecting infected cells from ADCC responses. However, gp120 shed from infected cells can bind to CD4 present on uninfected bystander cells, sensitizing them to ADCC mediated by CD4i antibodies (Abs)...

REVIEW
Olivia Falconer, Marie-Louise Newell, Christine E Jones
The success of prevention of mother to child transmission programs over the last two decades has led to an increasing number of infants who are exposed to human immunodeficiency virus (HIV), but who are not themselves infected (HIV-exposed, uninfected infants). Although the morbidity and mortality among HIV-exposed, uninfected infants is considerably lower than that among HIV-infected infants, they may remain at increased risk of infections in the first 2 years of life compared with their HIV-unexposed peers, especially in the absence of breastfeeding...

OBJECTIVE: Conflicting data exist regarding the impact of in utero exposure to maternal combination antiretrovirals. We compared neurodevelopmental outcomes between HIV-exposed/uninfected (HEU) children exposed in utero to 3-drug combination antiretroviral therapy (ART) versus zidovudine (ZDV) monotherapy. DESIGN: Prospective study of child neurodevelopment, nested within two cohorts of HIV-infected mothers and their children in Botswana (one observational, one interventional)...

BACKGROUND: Congenital cytomegalovirus (CMV) infection (cCMV) is an important cause of hearing loss and cognitive impairment. Prior studies suggest that HIV-exposed children are at higher risk of acquiring cCMV. We assessed the presence, magnitude, and risk factors associated with cCMV among infants born to HIV-infected women, who were not receiving antiretrovirals during pregnancy. METHODS: cCMV and urinary CMV load were determined in a cohort of infants born to HIV-infected women not receiving antiretrovirals during pregnancy...

Women involved in the criminal justice system (WICJ) are at high risk of acquiring HIV and would benefit from HIV pre-exposure prophylaxis (PrEP) but there are no studies in this population to inform PrEP implementation programs. We conducted a cross-sectional survey of HIV-uninfected, cis-gender women on probation, parole and/or recently released from prison/jail to assess PrEP awareness, eligibility, potential barriers to uptake, and the PrEP care continuum. The 125 WICJ surveyed reported high rates of HIV risk behaviors including recent transactional sex (22...

As youth with perinatally acquired HIV infection age, there is a need for studies that identify predictors and correlates of sexual risk behaviors. We examined the association between psychiatric disorders and substance use disorders (SUD) with sexual risk behaviors in youth with perinatally acquired HIV infection and perinatally HIV-exposed but uninfected youth. Participants were recruited from four medical centers in New York City. The Diagnostic Interview Schedule for Children and the Adolescent Sexual Behavior Assessment were administered to assess psychiatric disorders and sexual behaviors, respectively...

Regulatory B cells (Bregs) have been shown to be present during several disease states. The phenotype of the cells is not completely defined and the function of these cells differ between disease. The presence of FASL expressing (killer) B cells during latent and successfully treated TB disease have been shown but whether these cells are similar to regulatory B cells remain unclear. We assessed the receptor expression of FASL/IL5 (killer B cells), CD24/CD38 (regulatory B cells) on whole peripheral blood of participants with untreated active TB and healthy controls...

We evaluated the association between HIV exposed-uninfected (HEU) status, malnutrition, and risk of death in Ugandan children hospitalized with pneumonia. Both HIV exposure and infection were associated with lower anthropometric indices on univariate analysis, and mid-upper arm circumference was significantly associated with overall mortality (OR 0.96) in a multivariable model. HIV infection (OR 5.0) but not HEU status was associated with overall mortality. Malnutrition may contribute to poor pneumonia outcomes among HIV-infected and HEU children requiring hospitalization...

Pathogen sensing and recognition through pattern recognition receptors, and subsequent production of pro-inflammatory cytokines, is the cornerstone of the innate immune system. Despite the fact that HIV-exposed uninfected (HEU) infants are prone to serious bacterial infections, no study has focused on the functionality of their bacteria recognition system. This is the first study to investigate baseline levels of three critically important immune response molecules in this population: complement component (C)-3, toll-like receptor (TLR)-4, and C-reactive protein (CRP)...

Young HIV-exposed children are at high risk for TB infection. We performed QuantiFERON®-TB Gold (QFT) among HIV-exposed children in South Africa at enrolment and one year follow-up. The incidence of TB infection was high for HIV+ (11 cases/100 child-years) and HIV-exposed uninfected (HEU) children (15 cases/100 child-years). QFT may identify HIV-exposed children at risk for TB disease progression.

Long-term outcomes of perinatal exposure to maternal antiretroviral therapy in HIV-exposed uninfected (HEU) children are unknown. However, both HIV antiretroviral therapy and autism spectrum disorder (ASD) have been associated with mitochondrial alterations. Leukocyte mitochondrial DNA (mtDNA) content can serve as a marker for mitochondrial dysfunction. In this cross-sectional, nested case-control study, HEU children with ASD were matched approximately 1:3 on age, sex, and ethnicity to HEU children without ASD, HIV-unexposed uninfected (HUU) controls, and HUU children with ASD...

BACKGROUND: In low and middle-income countries, including South Africa, the epidemiology of pertussis in relation to immunisation, nutritional and HIV status is poorly described. We report on risk factors in South African children hospitalised with pertussis. METHODS: We conducted a prospective, hospital-based, sentinel surveillance programme for pertussis in Gauteng Province, South Africa. Hospitalised children (≤10 years) meeting the surveillance criteria for clinically suspected pertussis were screened and enrolled...

CONTEXT: HIV-infected (HIV+) children have worse neurodevelopmental outcomes compared with HIV-uninfected children. However, little is known regarding the differences in neurodevelopment between young HIV+ children, HIV-exposed but uninfected (HEU) children, and HIV-unexposed and uninfected (HUU) children. OBJECTIVE: To systematically review and meta-analyze data on neurodevelopmental performance between young HIV+, HEU, and HUU children. DATA SOURCES: We systematically searched the following electronic bibliographic databases: Ovid Medline, Embase, PsycINFO, Education Resources Information Center, and the Cochrane Database of Systematic Reviews...

Human immunodeficiency virus (HIV) infection significantly affect neurodevelopmental and behavioral outcomes. We investigated whether alterations of gray matter organization and structural covariance networks with vertical HIV infection adolescents exist, by using the GAT toolbox. MRI data were analysed from 25 HIV vertically infected adolescents and 33 HIV-exposed-uninfected control participants. The gray matter volume (GMV) was calculated, and structural brain networks were reconstructed from gray matter co-variance...

Background: Prevention of mother-to-child transmission of human immunodeficiency virus (HIV) with antiretroviral therapy (ART) has been highly successful. However, HIV-exposed uninfected (HIV-EU) infants might be at increased risk for low birth weight and/or preterm birth. We compared the birth weights and gestational ages of HIV-EU infants to those of HIV-unexposed control infants in Bronx, New York, an epicenter of the HIV epidemic in the United States. Methods: This study was performed with a retrospective cohort of HIV-EU infants born at Montefiore Medical Center between 2008 and 2012 and HIV-unexposed control infants...

BACKGROUND: Perinatally HIV-exposed but uninfected (HEU) children have elevated risk of late language emergence at age 1 year, with possible links to in utero antiretroviral (ARV) exposure. We investigated possible risks for speech impairments (SI) and language impairments (LI) in preschool monolingual HEU children in the United States. METHODS: Speech and language assessments were conducted as part of the PHACS Surveillance Monitoring of ART Toxicities (SMARTT) study at ages 3 (N= 208) and 5 (N = 429) years...
