Studies have observed neurodevelopmental (ND) challenges among young children perinatally HIV-exposed yet uninfected (CHEU) with in utero antiretroviral (ARV) exposure, without clear linkage to specific ARVs. Atazanavir (ATV) boosted with ritonavir has been a preferred protease inhibitor recommended for pregnant women, yet associations of ATV with ND problems in CHEU have been reported. Studies among early school-age children are lacking.
View Article and Find Full Text PDFBackground: To collect and compare selected hearing measures in a pilot study of young adults with perinatally acquired HIV (YAPHIV) and those with perinatal HIV exposure who are uninfected young adults with PHEU (YAPHEU).
Setting: Cross-sectional hearing measures in YAPHIV and YAPHEU enrolled in the Pediatric HIV/AIDS Cohort Study Adolescent Master Protocol (AMP) for Participants 18 Years of Age and Older (AMP Up).
Methods: Pure-tone air conduction audiometry and distortion product otoacoustic emission (DPOAE) data were collected in 1 visit.
Background: CMV infection of the fetus or neonate can lead to devastating disease, and there are no effective prevention strategies to date. Vitamin D is a potent immunomodulator, supports antiviral immune responses, and plays an important role in placental immunity.
Methods: Retrospective cohort study to evaluate the impact of low maternal vitamin D on congenital and early postnatal transmission of CMV among HIV-infected, non-breastfeeding women and their HIV exposed but negative infants from an urban HIV clinic.
Background: Global immune activation and HLA alleles are each associated with the pathogenesis of human immunodeficiency virus (HIV) and hepatitis C virus .
Methods: We evaluated the relationship between 44 HLA class I and 28 class II alleles and percentages of activated CD8 (CD8+CD38+DR+) and CD4 (CD4+CD38+DR+) T cells in 586 women who were naive to highly active antiretroviral therapy. We used linear generalized estimating equation regression models, adjusting for race/ethnicity, age, HIV load, and hepatitis C virus infection and controlling for multiplicity using a false discovery rate threshold of 0.
Objectives: To estimate birth prevalence of congenital cytomegalovirus (cCMV) in HIV-exposed uninfected children born in the current era of combination antiretroviral therapy and describe cCMV-related neurodevelopmental and hearing outcomes.
Study Design: The Surveillance Monitoring for ART Toxicities cohort study follows HIV-exposed uninfected children at 22 sites in the US and Puerto Rico. Birth cCMV prevalence was estimated in a subset of participants who had blood pellets collected within three weeks of birth and underwent ≥1 of 6 assessments evaluating cognitive and language development including an audiologic examination between 1 and 5 years of age.
Objective: To examine the association of vitamin D insufficiency and risk of pregnancy-induced hypertension (PIH) among human immunodeficiency virus (HIV)-infected pregnant women.
Study Design: This is a retrospective cohort study evaluating the impact of low maternal vitamin D levels on PIH and perinatal outcomes among HIV-infected pregnant women receiving care at an urban HIV center from 1991 to 2014.
Results: A total of 366 pregnant women were included, of which 11% developed PIH.
Background: Perinatally HIV-exposed but uninfected (HEU) children have elevated risk of late language emergence at 1 year of age, with possible links to in utero antiretroviral (ARV) exposure. We investigated possible risks for speech impairments (SIs) and language impairments (LI) in preschool monolingual HEU children in the United States.
Methods: Speech and language assessments were conducted as part of the Pediatric HIV/AIDS Cohort Study Surveillance Monitoring of ART Toxicities study at ages 3 (N = 208) and 5 (N = 429) years.
Objective: We sought to describe the current status of perinatal HIV exposure surveillance (PHES) activities and regulations in the United States and to make recommendations to strengthen PHES.
Methods: In 2014, we sent an online survey to health departments in the 50 states, District of Columbia, Puerto Rico, Virgin Islands, and 6 cities and counties (Chicago, Illinois; Houston, Texas; Los Angeles, California; New York, New York; Philadelphia, Pennsylvania; and San Francisco, California). We analyzed responses from 56 of the 59 (95%) jurisdictions.
Background: Language impairment (LI) risk is increased for perinatally acquired human immunodeficiency virus-infected (PHIV) and perinatally exposed to HIV but uninfected (PHEU) youth. This study evaluates the persistence of LI in these groups.
Methods: The Clinical Evaluation of Language Fundamentals was repeated on participants of the Pediatric HIV/AIDS Cohort Study Adolescent Master Protocol 18 months postbaseline.

HIV-related stigma affects people living with HIV (PLWH), especially in communities of color. In our study, African American and Latina/Hispanic women living with HIV (WLWH) described experiences of stigma through PhotoVoice, a community-based participatory method of documentary photography. Ten WLWH from Los Angeles documented stigma experiences through photographs for up to 5 weeks and discussed their images during a focus group or semi-structured individual interview.

Objectives: Hepatitis C virus (HCV) infection causes an alteration in T-cell maturation and activation in patients coinfected with human immunodeficiency virus (HIV). Because interleukin 7 (IL-7) is a major cytokine controlling T-cell homeostasis, we analyzed the potential influence of HCV coinfection on circulating IL-7 levels in HIV-infected women before and after highly active antiretroviral therapy (HAART).
Design And Methods: This prospective study included 56 HIV monoinfected, 55 HIV/HCV coinfected without HCV viremia, 132 HIV/HCV coinfected with HCV viremia, and 61 HIV/HCV-uninfected women for whom plasma levels of IL-7 were determined by enzyme-linked immunosorbent assay at 1 or more follow-up visits before and after HAART.

Background: Plasma HIV RNA is the most significant determinant of cervical HIV shedding. However, shedding is also associated with sexually transmitted infections (STIs) and cervical inflammation. The mechanism by which this occurs is poorly understood.
View Article and Find Full Text PDFObjective: To investigate whether prenatal atazanavir (ATV) exposure, assessed by meconium antiretroviral (ARV) quantification, predicts early child language outcomes. Prenatal ATV exposure previously was associated with poorer language development in 1-year olds.
Methods: Pregnant women with HIV and their uninfected infants enrolled in the Surveillance Monitoring of Antiretroviral Therapy Toxicities study.
Background: Combination antiretroviral (cARV) regimens are recommended for pregnant women with HIV to prevent perinatal HIV transmission. Safety is a concern for infants who were HIV-exposed but uninfected, particularly for neurodevelopmental problems, such as language delays.
Methods: We studied late language emergence (LLE) in HIV-exposed but uninfected children enrolled in a US-based prospective cohort study.
Objective: CD4 and CD8 T-cell activation are independent predictors of AIDS. The complete activation profile of both T-cell subtypes and their predictive value for AIDS risk is largely unknown.
Design: A total of 564 AIDS-free women in the Women's Interagency HIV Study were followed over 6.
Background. Methicillin-resistant Staphylococcus aureus (MRSA) infection incidence has increased in healthy US children. Our objective was to evaluate MRSA incidence and correlates in HIV-infected youth.
View Article and Find Full Text PDFBackground: Before highly active antiretroviral therapy (HAART), congenital cytomegalovirus (CMV) rates were higher among human immunodeficiency virus (HIV)-exposed infants than unexposed infants. This study examines congenital and perinatal/early postnatal (P/EP) CMV among HIV-exposed infants pre- and post- HAART.
Methods: Infants born to HIV-infected women were evaluated for congenital CMV (CMV-positive culture in first 3 weeks of life) and P/EP CMV (positive culture in first 6 months of life).
Objective: To investigate the risk for language impairment (LI) in children perinatally infected or exposed to HIV.
Methods: We evaluated the prevalence of LI in 7- to 16-year-old children with perinatal HIV infection (HIV+) compared with HIV-exposed and uninfected children, using a comprehensive standardized language test (Clinical Evaluation of Language Functioning-Fourth Edition [CELF-4]). LI was classified as primary LI (Pri-LI) (monolingual English exposure and no cognitive or hearing impairment), concurrent LI (Con-LI) (cognitive or hearing impairment), or no LI.
Background: Because activation of T cells is associated with human immunodeficiency virus (HIV) pathogenesis, CD4 and CD8 activation levels in patients coinfected with HIV and hepatitis C virus (HCV) may explain conflicting reports regarding effects of HCV on HIV disease progression.
Methods: Kaplan-Meier and multivariate Cox regression models were used to study the risk of incident clinical AIDS and AIDS-related deaths among 813 HCV-negative women with HIV infection, 87 HCV-positive nonviremic women with HIV coinfection, and 407 HCV-positive viremic women with HIV coinfection (median follow-up time, 5.2 years).
Although the primary mode of hepatitis C virus (HCV) transmission is exposure to blood products or injection drug use (IDU), studies have found varying independent risk factors for HCV infection among persons with no history of IDU or exposure to blood products. For HIV-infected women, sexual transmission may be another potential source of HCV infection. HIV-infected and HIV-negative women at risk for HIV enrolled in the Women's Interagency HIV Study (WIHS) during October 1994 to November 1995 and again between October 2001 and November 2002 were studied.

Methods: We examined trends in hospitalization rates between 1990-2002 among 3,927 children/youths with perinatal HIV infection, ranging in age from newborn to 21 years. We used Poisson regression to test for trends in hospitalization rates by age and year; binomial regression to test for trends in intensive care unit (ICU) admissions and hospitalization at least once and more than once, by age and year; and multivariate logistic regression to examine factors associated with hospitalization, ICU admission, and hospitalization longer than 10 days.
Objective: To evaluate the impact of hepatitis C virus (HCV) on the immune system before receipt of highly active antiretroviral therapy (HAART) and on immune recovery after receipt of HAART among human immunodeficiency virus (HIV)/HCV-coinfected women enrolled in the Women's Interagency HIV Study.
Methods: The study included 294 HIV-infected women who initiated HAART and attended 2 follow-up visits. The women were grouped on the basis of positive HCV antibody and HCV RNA tests.
Background: In the United States, HIV-infected children and adolescents are aging and using antiretroviral (ARV) therapy for extended periods of time.
Objective: To assess trends in ARV use and long-term survival in an observational cohort of HIV-infected children and adolescents in the United States.
Methods: The Pediatric Spectrum of HIV Disease Study (PSD) is a prospective chart review of more than 2000 HIV-infected children and adolescents.
