- Abstract
OBJECTIVES: The purpose of this work was to examine the effects of HIV infection and the impact of highly active antiretroviral treatment with protease inhibitors on neurodevelopmental functioning during the first 3 years of life. PATIENTS AND METHODS: Pediatric AIDS Clinical Trials Group 219/219C is a longitudinal cohort study that has enrolled HIV-infected (HIV+) and HIV-exposed but uninfected (HIV-) infants and children since 1993. Longitudinal profiles of neurodevelopmental functioning as measured by the Bayley Scales of Infant Development were compared by HIV-infection status before and after the availability of highly active antiretroviral therapy with a protease inhibitor and within infants with Bayley tests available before and after initiating protease inhibitor therapy. RESULTS: In the pre-protease inhibitor era, mean mental and motor scores in HIV+ (n = 54) infants <1 year of age were significantly lower than those among HIV- infants (n = 221) and remained lower up to 2 years of age. After protease inhibitors became available, mean mental and motor functioning of HIV+ infants (n = 91) <1 year of age were still significantly lower than those of HIV- infants (n = 838). However, against a background of declining scores among the HIV- infants, there was evidence of limited improvement in the HIV+ infants relative to their uninfected peers. Among infants who had Bayley II evaluations before and after starting a protease inhibitor, there was a trend to improved mental and motor scores after initiation of protease inhibitor therapy. CONCLUSIONS: The suppression of systemic viral replication and subsequent substantial improvements in survival and immunologic status brought about by highly active antiretroviral therapy have been followed by limited improvements in neurodevelopmental functioning in young children. Additional longitudinal research is needed to better understand the role of antiretroviral therapy as well as the impact of genetic and environmental factors on neurodevelopmental functioning in children affected by HIV.

- Abstract
Perinatally acquired human immunodeficiency virus (HIV) has the potential to affect neurodevelopment and long-term cognitive and behavioral outcomes. Early, consistent viral suppression through antiretroviral therapy is a priority for protection of neurodevelopment. Monitoring of neurodevelopment and cognitive functioning, referral for appropriate interventions, caregiver/family support, and assessment of mental health, socioeconomic, and environmental risks are important to optimize health and well-being. Support for medication and health care adherence may be necessary to sustain best outcomes., Competing Interests: Disclosure The authors have nothing to disclose., (Copyright © 2024 Elsevier Inc.

- Abstract
Objective: Central nervous system (CNS) HIV infection can impact cognition and may be an obstacle to cure in adolescents and young adults with perinatal HIV (AYAPHIV). IMPAACT2015 enrolled AYAPHIV on suppressive antiretroviral therapy (ART) with cognitive impairment to detect and quantify HIV in blood and cerebrospinal fluid (CSF)., Design: IMPAACT2015 was a U.S.-based multi-site, exploratory, observational study., Methods: Cognitive impairment was defined as NIH Toolbox Fluid Cognition Composite score (FCCS) more than 1 standard deviation below age-adjusted normative group mean. Cell-free HIV-RNA and cell-associated HIV pol/gag -DNA and 10 biomarkers of inflammation/neuronal injury were measured in paired CSF and blood. ART exposure concentrations were quantified in hair., Results: Among 24 participants, 20 had successful CSF collection and 18 also met viral suppression criteria. Nine of 18 (50%) were female sex-at-birth, and 14 of 18 (78%) were black. Median (range) age was 20 years (13-27), time on ART was 18.3 years (8.0-25.5), and FCCS was 68 (53-80). HIV-DNA was detected in PBMCs from all participants. In CSF, two of 18 (11%, 95% CI: 1.4-34.7%) participants had detectable cell-free HIV-RNA, while HIV gag or pol -DNA was detectable in 13 of 18 (72%, 95% confidence interval: 47-90). Detectable HIV-DNA in CSF was associated with male sex-at-birth ( P = 0.051), lower CD4 + cell count at enrollment ( P = 0.016), and higher PBMC HIV pol -DNA copies ( P = 0.058). Hair antiretroviral concentrations and biomarkers were not associated with CSF HIV-DNA detection., Conclusion: We found that a high proportion of AYAPHIV with neurocognitive impairment had CSF cells harboring HIV-DNA during long-term virologic suppression. This evidence of persistent HIV-DNA in CSF suggests that the CNS should be considered in treatment and cure studies., (Copyright © 2024 The Author(s). Published by Wolters Kluwer Health, Inc.)

- Abstract
Introduction: Over 265 000 women are living with HIV in the USA, but limited research has investigated the physical, mental and behavioural health outcomes among women living with HIV of reproductive age. Health status during the reproductive years before, during and after pregnancy affects pregnancy outcomes and long-term health. Understanding health outcomes among women living with HIV of reproductive age is of substantial public health importance, regardless of whether they experience pregnancy. The Health Outcomes around Pregnancy and Exposure to HIV/Antiretrovirals (HOPE) study is a prospective observational cohort study designed to investigate physical and mental health outcomes of young women living with HIV as they age, including HIV disease course, engagement in care, reproductive health and choices and cardiometabolic health. We describe the HOPE study design, and characteristics of the first 437 participants enrolled as of 1 January 2024., Methods and Analysis: The HOPE study seeks to enrol and follow 1630 women living with HIV of reproductive age, including those with perinatally-acquired HIV, at 12 clinical sites across 9 US states and Puerto Rico. HOPE studies multilevel dynamic determinants influencing physical, mental and social well-being and behaviours of women living with HIV across the reproductive life course (preconception, pregnancy, post partum, not or never-pregnant), informed by the socioecological model. Key research areas include the clinical course of HIV, relationship of HIV and antiretroviral medications to reproductive health, pregnancy outcomes and comorbidities and the influence of racism and social determinants of health. HOPE began enrolling in April 2022., Ethics and Dissemination: The HOPE study received approval from the Harvard Longwood Campus Institutional Review Board, the single institutional review board of record for all HOPE sites. Results will be disseminated through conference presentations, peer-reviewed journals and lay summaries., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

- Abstract
Objective: Deficits in neurocognitive functioning are common among adolescents and young adults (AYA) with perinatally acquired HIV (PHIV). Limitations of traditional neuropsychological tests hinder assessment of neurocognition in low- and middle-income countries where most AYA with PHIV reside. Computerized testing could make assessment of neurocognition more accessible in these countries. This study examined a culturally modified NeuroScreen , a tablet-based neurocognitive testing app, for use in Thailand. Construct validity was examined among Thai AYA (13-23 years) with and without PHIV., Method: NeuroScreen underwent adaptation including language, content, and usability review by Thai psychologists, AYA, and clinical staff. One hundred Thai AYA (50 PHIV; 50 HIV-uninfected, matched controls) were administered the adapted NeuroScreen and a battery of traditional paper-and-pencil neuropsychological tests. Correlations, mean differences, and proportions with impaired performance were examined across NeuroScreen and the traditional tests., Results: The Thai version of NeuroScreen was deemed understandable and culturally appropriate. A large correlation (.82) between overall performance on the NeuroScreen and traditional batteries was observed. Small-to-large correlations were found between conceptually similar NeuroScreen and traditional tests of processing speed, working memory, motor speed, and executive functioning. Mean test performance differences between AYA with PHIV and controls were similar between test batteries. Both sets of tests identified similar rates of impaired participants., Conclusions: Results provide support for the acceptability and construct validity of the Thai NeuroScreen tests to assess neurocognition in Thai AYA with PHIV. An easy-to-use tool to assess neurocognition can help Thai providers provide better care for AYA with PHIV. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

- Abstract
This study examined associations of self-regulatory behavior and cognitive functioning with substance use (SU) to inform interventions for youth with perinatal HIV infection (YPHIV) or exposure but uninfected (YPHEU). Youth aged 7-15 years (YPHIV, n = 390; YPHEU, n = 211) were followed longitudinally with cognitive testing and behavioral questionnaires including self-report of alcohol, marijuana, tobacco, and other SU. Cox proportional hazards analyses were used to examine correlates of initiating each substance for those without prior use at baseline and generalized estimating equation analyses were used to address associations of cognitive/behavioral measurements with SU prevalence for the entire sample. Lower self-reported self-regulation skills, but higher cognitive functioning abilities, were associated with initiation and prevalent use of alcohol and marijuana regardless of HIV status. Our findings suggest SU screening tools and self-regulation interventions developed for general adolescent populations should be implemented for those with PHIV, who may be at heightened risk for SU-related health consequences., (© 2021.

- Abstract
Objective: To develop a predictive model of neurocognitive trajectories in children with perinatal HIV (pHIV)., Design: Machine learning analysis of baseline and longitudinal predictors derived from clinical measures utilized in pediatric HIV., Methods: Two hundred and eighty-five children (ages 2-14 years at baseline; Mage = 6.4 years) with pHIV in Southeast Asia underwent neurocognitive assessment at study enrollment and twice annually thereafter for an average of 5.4 years. Neurocognitive slopes were modeled to establish two subgroups [above (n = 145) and below average (n = 140) trajectories). Gradient-boosted multivariate regressions (GBM) with five-fold cross validation were conducted to examine baseline (pre-ART) and longitudinal predictive features derived from demographic, HIV disease, immune, mental health, and physical health indices (i.e. complete blood count [CBC])., Results: The baseline GBM established a classifier of neurocognitive group designation with an average AUC of 79% built from HIV disease severity and immune markers. GBM analysis of longitudinal predictors with and without interactions improved the average AUC to 87 and 90%, respectively. Mental health problems and hematocrit levels also emerged as salient features in the longitudinal models, with novel interactions between mental health problems and both CD4 cell count and hematocrit levels. Average AUCs derived from each GBM model were higher than results obtained using logistic regression., Conclusion: Our findings support the feasibility of machine learning to identify children with pHIV at risk for suboptimal neurocognitive development. Results also suggest that interactions between HIV disease and mental health problems are early antecedents to neurocognitive difficulties in later childhood among youth with pHIV.

- Abstract
Background: Large numbers of perinatally HIV-infected (PHIV) children are aging into adolescence. We examined cognitive and behavioral outcomes in a longitudinal cohort of Asian youth., Methods: We followed up 231 PHIV, 125 perinatally HIV-exposed, uninfected (HEU), and 138 HIV-unexposed, uninfected (HUU) adolescents (aged 10 years and older), matched by age/sex, in Thailand and Cambodia for 3 years. Executive function was assessed with Children's Color Trails Tests 1 and 2 (CCTT-1 and -2), the design fluency test, and the verbal fluency test. Working memory (Freedom from Distractibility Index) and processing speed index were assessed using WISC-III. Visual memory was assessed by design memory and design recognition subtests of the Wide Range Assessment of Memory and Learning (WRAML-2) and behavioral problems using the Child Behavior Checklist (CBCL). Generalized estimating equations examined adjusted odds ratios of cognitive impairment (Z-scores ≥2 SD below age-adjusted means of the HUU group) and CBCL T-scores in the borderline-clinical range (T-Scores ≥60) in PHIV and HEU versus HUU youth, adjusting for ethnicity, household income, and caregiver characteristics., Results: The median age at enrollment was 13.8 years, with 58% women and 63% Thai participants. PHIV youth had >86% virological suppression and significantly higher impairment rates on CCTT-1 and -2 tests, design fluency test, verbal fluency tests, design memory, and CBCL internalizing and externalizing problems. Results were mostly similar between HEU and HUU groups, apart from higher impairment rates on CCTT-1 and internalizing problems in HEU., Conclusion: Asian adolescents with PHIV remain at risk of cognitive and mental health problems despite HIV treatment. Selective risks are observed among HEU youth.

- Abstract
Objectives: Psychosocial challenges associated with perinatally acquired HIV (PHIV) infection are well known, yet many children infected with HIV since birth demonstrate positive outcomes, referred to as resilience. The purpose of this study was to evaluate emotional-behavioral development and identify salient predictors of resilience among long-term survivors of PHIV., Design: Prospective investigation of children with PHIV compared with demographically similar perinatally HIV-exposed but uninfected (PHEU) and HIV-unexposed, uninfected (HUU) children, all from Thailand and Cambodia., Methods: The Child Behavior Checklist (CBCL; parent version) was administered at baseline and annual follow-up visits (median follow-up of 3 years) to children age 6-14. Resilience was defined as consistent CBCL scores on the Internalizing, Externalizing or Total Problem T scales within normative ranges (T-scores <60) at every time point. Generalized estimating equations examined CBCL scores over time and logistic models examined demographic, socioeconomic, and cultural predictors of resilience., Results: Participants included 448 children (236 PHIV, 98 PHEU, 114 HUU), with median (interquartile range) age at first evaluation of 7 (6-9) years. Children with PHIV exhibited similar rates of resilience as PHEU and HUU on the Externalizing and Total Problems scales. Resilience on the Internalizing scale was more likely in PHEU (71%) compared with PHIV (59%) or HUU (56%), P = 0.049. Factors associated with resilience in adjusted models included: HIV-exposed but uninfected status, higher household income, Cambodian nationality, female sex, and caregiver type., Conclusion: Despite biopsychosocial risks, resilience is observed among PHIV and PHEU children. Further study is needed to understand mechanisms underlying associated factors and intervention priorities.

- Abstract
Among perinatally HIV-infected (PHIV) and perinatally HIV-exposed, uninfected (PHEU) youth, we evaluated the contributions of home environment, psychosocial, and demographic factors and, among PHIV only, HIV disease severity and antiretroviral treatment (ART), to cognitive functioning (CF) and behavioral functioning (BF). A structural equation modeling (SEM) approach was utilized. Exploratory factor analysis was used to reduce predictor variables to major latent factors. SEMs were developed to measure associations between the latent factors and CF and BF outcomes. Participants included 231 PHIV and 151 PHEU youth (mean age = 10.9 years) enrolled in the PHACS adolescent master protocol. Youth and caregivers completed assessments of CF, BF, psychosocial factors and HIV health. Medical data were also collected. Clusters of predictors were identified, establishing four parsimonious SEMs: child-assessed and caregiver-assessed BF in PHIV and PHEU youth. Among both groups, higher caregiver-child stress predicted worse BF. Caregiver resources and two disease severity variables, late presenter and better past HIV health, were significant predictors of CF in PHIV youth. Higher youth CF was associated with better caregiver-reported BF in both groups. Caregiver resources predicted caregiver-reported BF in PHEU youth, which was mediated via youth CF. Among PHIV youth, better past HIV health and caregiver resources mediated the effects of CF on caregiver-assessed BF. Using SEMs, we found a deleterious impact of caregiver and child stress on BF in both groups and of HIV disease factors on the CF of PHIV youth, reinforcing the importance of early comprehensive intervention to reduce risks for impairment.

- Abstract
Background: Medication adherence is a critical but challenging developmental task for children and adolescents with perinatally acquired HIV (PHIV). Understanding how medication responsibility, executive functions (EFs) and adaptive functioning (AF) influence adherence may help prepare adolescents for transition to adulthood., Methods: Participants included PHIV children and adolescents 7-16 years of age enrolled in the Pediatric HIV/AIDS Cohort Study Adolescent Master Protocol, who were prescribed antiretroviral medications. Measures included caregiver report and child self-report measures of adherence, medication responsibility and EF, caregiver report of child AF, examiner-administered tests of EF and processing speed and demographic and health characteristics., Results: Two hundred fifty-six participants with PHIV (mean age: 12 years old) were 51% female, 80% black and 79% non-Hispanic. Per 7-day recall, 72% were adherent (no missed doses). Children/adolescents self-reported that 22% had sole and 55% had shared medication responsibility. Adjusted logistic models revealed significantly higher odds of adherence with sole caregiver responsibility for medication [odds ratio (OR): 4.10, confidence interval (CI): 1.43-11.8, P = 0.009], child nadir CD4% <15% (OR: 2.26, CI: 1.15-4.43, P = 0.018), better self-reported behavioral regulation (OR: 0.65, CI: 0.44-0.96, P = 0.029) and slower processing speed (OR: 0.54, CI: 0.38-0.77, P < 0.001), adjusting for demographic variables (age, race and caregiver education)., Conclusions: Among children and adolescents with PHIV, continued caregiver medication management, especially during adolescence, is essential. Although global EF and AF were not significantly associated with adherence, behavioral regulation was. Given that EF and AF develop throughout adolescence, their relationships to adherence should be evaluated longitudinally, especially as youth transition to adulthood and caregiver responsibility diminishes.

- Abstract
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. Among PHIV youth, associations of baseline and past disease severity with memory and EF performance at follow-up were evaluated using adjusted linear regression models., Results: Participants were primarily black (79%); 16% were Hispanic; 55% were female. Mean memory and EF scores at follow-up generally fell in the low-average to average range. Pairwise comparison of adjusted mean change from baseline to follow-up revealed significantly greater change for PHIV/non-C compared with PHEU youth in only one verbal recognition task, with a difference in mean changes for PHIV/non-C versus PHEU of -0.99 (95% CI: -1.80 to -0.19; P = 0.02). Among youth with PHIV, better immunologic status at baseline was positively associated with follow-up measures of verbal recall and recognition and cognitive inhibition/flexibility. Past AIDS-defining diagnoses and higher peak viral load were associated with lower performance across multiple EF tasks at follow-up., Conclusions: Youth with PHIV demonstrated stable memory and EF during a 2-year period of adolescence, allowing cautious optimism regarding long-term outcomes.

- Abstract
Background: Perinatally acquired HIV (PHIV) confers risk for neurocognitive impairment, which potentially affects school performance and functional independence of infected children. In this study, we examined the associations of 2 key neurocognitive domains, memory and executive function (EF), with academic and adaptive skills among youth with PHIV and perinatally HIV-exposed but uninfected (PHEU) youth., Methods: Participants ages 9 to <19 years enrolled in the Pediatric HIV/AIDS Cohort Study's Memory and Executive Functioning Study completed standardized measures of reading and math. The primary caregivers completed a standardized measure of their child's adaptive behavior. Participants with PHIV, those with (PHIV/C) and without (PHIV/non-C) a Centers for Disease Control and Prevention class C diagnosis, and PHEU participants were compared. Retrospective memory (RM), prospective memory (PM), and EF were evaluated relative to outcomes using general linear regression models adjusted for sociodemographic characteristics., Results: Of the participants (N = 258; mean age, 14.1 years), 46% were male, 75% were black, and 18% were Hispanic. Adjusted mean scores in math and adaptive behavior did not differ among the youth with PHIV/C (n = 45), those with PHIV/non-C (n = 128), and PHEU youth (n = 85). Youth with PHIV/C had lower adjusted mean reading scores than PHIV/non-C and PHEU youth (86.9 vs 93.8 [P = .02] and 93.2 [P = .04], respectively). There were positive associations of RM, PM, EF, and some sociodemographic characteristics with higher reading and math scores. Immediate and delayed verbal memory, delayed visual memory, PM, and some EF measures were positively associated with adaptive behavior., Conclusions: Higher-order cognitive abilities such as memory and EF seem to play a key role in academic and adaptive capacities, regardless of a child's HIV status, and might serve as intervention targets for improving functional outcomes., (© The Author 2016.

- Abstract
Background: Executive functions (EFs) are critical for management of life activities, but few studies have evaluated EFs in children and adolescents with perinatally acquired HIV (PHIV), who are at risk for problems in academics, behavior, and medication adherence. We compared EFs in youth with PHIV and in perinatally HIV-exposed but uninfected (PHEU) youth., Methods: Four Delis-Kaplan Executive Function System (D-KEFS) subtests were administered to 173 youth with PHIV and 85 PHEU youth, aged 9 to <19 years, who were enrolled in the Pediatric HIV/AIDS Cohort Study (PHACS) Memory and Executive Functioning Study. Youth with PHIV, with or without history of a Centers for Disease Control and Prevention Class C (AIDS-defining) condition (PHIV/C [n = 45] and PHIV/non-C [n = 128], respectively), were compared with each other and with PHEU youth. Among youth with PHIV, associations with measures of current and past disease severity were evaluated using adjusted linear regression models., Results: The PHIV/C group (mean age, 15.5 years), compared with the PHIV/non-C and PHEU groups (mean ages, 14.5 and 12.9 years, respectively), were significantly slower on the Inhibition and Color Naming/Reading Combined conditions of the Color-Word Interference subtest and made more errors on Inhibition; differences between the PHIV/C and PHEU groups persisted in adjusted models. No differences in adjusted means for fluency or problem-solving were found. The PHIV/non-C and PHEU groups did not differ on any measure. Associations of specific EF measures with HIV RNA viral load, CD4-positive T-lymphocyte percentage, and age at greatest disease severity were observed., Conclusions: Youth with PHIV and previous AIDS-defining conditions performed more poorly on some EF measures. Relationships of EF development with the degree and timing of disease severity require further study. Implications for long-term outcomes and interventions are important avenues for follow-up., (© The Author 2016.

- Abstract
Introduction: Adolescents are a unique and sometimes neglected group in the planning of healthcare services. This is the case in many parts of sub-Saharan Africa, where more than eight out of ten of the world's HIV-infected adolescents live. Although the last decade has seen a reduction in AIDS-related mortality worldwide, largely due to improved access to effective antiretroviral therapy (ART), AIDS remains a significant contributor to adolescent mortality in sub-Saharan Africa. Although inadequate access to ART in parts of the subcontinent may be implicated, research among youth with HIV elsewhere in the world suggests that suboptimal adherence to ART may play a significant role. In this article, we summarize the epidemiology of HIV among sub-Saharan African adolescents and review their adherence to ART, emphasizing the unique challenges and factors associated with adherence behaviour., Methods: We conducted a comprehensive search of online databases for articles, relevant abstracts, and conference reports from meetings held between 2010 and 2014. Our search terms included "adherence," "compliance," "antiretroviral use" and "antiretroviral adherence," in combination with "adolescents," "youth," "HIV," "Africa," "interventions" and the MeSH term "Africa South of the Sahara." Of 19,537 articles and abstracts identified, 215 met inclusion criteria, and 148 were reviewed., Discussion: Adolescents comprise a substantial portion of the population in many sub-Saharan African countries. They are at particular risk of HIV and may experience worse outcomes. Although demonstrated to have unique challenges, there is a dearth of comprehensive health services for adolescents, especially for those with HIV in sub-Saharan Africa. ART adherence is poorer among older adolescents than other age groups, and psychosocial, socio-economic, individual, and treatment-related factors influence adherence behaviour among adolescents in this region. With the exception of a few examples based on affective, cognitive, and behavioural strategies, most adherence interventions have been targeted at adults with HIV., Conclusions: Although higher levels of ART adherence have been reported in sub-Saharan Africa than in other well-resourced settings, adolescents in the region may have poorer adherence patterns. There is substantial need for interventions to improve adherence in this unique population.

- Abstract
Background: Perinatal HIV (PHIV) infection may place youth at risk for impairments in executive functioning (EF). We examined associations of EF with HIV infection, disease severity and other factors among youth with PHIV and perinatally HIV-exposed, uninfected youth (PHEU)., Methods: Within the US-based Pediatric HIV/AIDS Cohort Study, 354 PHIV and 200 PHEU youth completed a standardized EF measure (Children's Color Trails Test, CCTT) and youth and/or caregivers completed a questionnaire measuring everyday EF (Behavior Rating Inventory of Executive Function, BRIEF). Covariates included HIV status, current and historical disease severity, demographic and caregiver variables and other cognitive measures. Analyses used linear and logistic regression and proportional odds models., Results: No significant HIV status group differences were found on CCTT scores. Caregiver BRIEF ratings indicated significantly fewer problems for PHIV than PHEU youth. However, PHIV youth with past encephalopathy self-endorsed significantly greater metacognitive (ie, cognitive regulation) problems on the BRIEF and performed more slowly on the CCTT than PHEU youth. CCTT and caregiver BRIEF scores had significant associations with indicators of past and present disease severity. Both PHIV and PHEU had significantly worse scores than population means on CCTT and BRIEF; scores had significant associations with demographic covariates., Conclusions: Youth with PHIV show EF problems likely associated with risk factors other than HIV. However, cognitive slowing and self-reported metacognitive problems were evident in PHIV youth with a history of encephalopathy. Assessment and treatment of EF impairment may be important to identifying PHIV youth at particular risk for poor health and behavioral outcomes.

- Abstract
Objectives: We investigated whether HIV disease severity was associated with alterations in structural brain connectivity, and whether those alterations in turn were associated with cognitive deficits in youth with perinatally acquired HIV (PHIV)., Design: PHIV youth (n = 40) from the Pediatric HIV/AIDS Cohort Study (PHACS) (mean age: 16 ± 2 years) were included to evaluate how current and past disease severity measures (recent/nadir CD4%; peak viral load) relate to white matter microstructure within PHIV youth. PHIV youth were compared with 314 controls from the Pediatric Imaging, Neurocognition and Genetics (PING) study., Methods: Diffusion tensor imaging and tractography were utilized to assess white matter microstructure. Mediation analyses were conducted to examine whether microstructure alterations contributed to relationships between higher disease severity and specific cognitive domains in PHIV youth., Results: Whole brain fractional anisotropy was reduced, but radial and mean diffusivity were increased in PHIV compared with control youth. Within PHIV youth, more severe past HIV disease was associated with reduced fractional anisotropy of the right inferior fronto-occipital (IFO) and left uncinate tracts; elevated mean diffusivity of the F minor; and increased streamlines comprising the left inferior longitudinal fasciculus (ILF). Associations of higher peak viral load with lower working memory performance were partly mediated by reductions in right IFO fractional anisotropy levels., Conclusion: Our findings suggest that PHIV youth have a higher risk of alterations in white matter microstructure than typically developing youth, and certain alterations are related to past disease severity. Further, white matter alterations potentially mediate associations between HIV disease and working memory.

- Abstract
Objective: To estimate the association of age of viral suppression and central nervous system penetration effectiveness (CPE) score with neurocognitive functioning among school-age children with perinatally acquired HIV infection (PHIV+)., Design: We analyzed data from two US-based multisite prospective cohort studies., Methods: Multivariable general linear regression models were used to evaluate associations of age at viral suppression and CPE scores (of initial antiretroviral therapy regimen and weighted average) with the Wechsler Intelligence Scale for Children, Third or Fourth Edition neurocognitive assessments [Full-Scale Intelligence Quotient (FSIQ); Performance IQ/Perceptual Reasoning Index (PIQ/PRI); and Verbal IQ/Verbal Comprehension Index (VIQ/VCI)], adjusted for demographic and clinical covariates. Sensitivity analyses were stratified by birth cohort (before versus after 1996)., Results: A total of 396 PHIV+ children were included. Estimated differences in mean FSIQ (comparing virally suppressed versus unsuppressed children) by each age cutoff were 3.7, 2.2, 3.2, 4.4, and 3.9 points at ages 1, 2, 3, 4, and 5, respectively. For PIQ/PRI, estimated mean differences were 3.7, 2.4, 2.2, 4.6, and 4.5 at ages 1 through 5, respectively. In both cases, these differences were significant only at the age 4 and 5 thresholds. After stratifying by birth cohort, the association between age at suppression and cognitive function persisted only among those born after 1996. Age at viral suppression was not associated with VIQ/VCI; CPE score was not associated with FSIQ, verbal comprehension, or perceptual reasoning indices., Conclusion: Virologic suppression during infancy or early childhood is associated with improved neurocognitive outcomes in school-aged PHIV+ children. In contrast, CPE scores showed no association with neurocognitive outcomes.

- Abstract
The prevalence of HIV-associated neurocognitive impairment in perinatally HIV-infected children has declined since the introduction of combination antiretroviral therapy (cART). Early initiation of cART in infancy has been shown to positively impact neurodevelopment; however, children continue to be diagnosed with HIV outside of the early infancy period and can experience subtle to severe neurocognitive deficits despite cART. The causes of these neurocognitive deficits despite effective cART are multifactorial and likely include continued viral replication in the CNS, ongoing neuroinflammation, irreversible CNS injury prior to cART initiation, neurotoxic effects of cART, and socioeconomic and psychosocial effects. Many aspects of our understanding of HIV-associated neurocognitive disorders have emerged from research in adult patients, but perinatally HIV-infected children represent a very different population. These children were exposed to HIV during a period of rapid brain development and have lifelong infection and potential lifelong cART exposure. HIV is no longer a rapidly fatal disease, and most HIV-infected children in resource-rich countries are living into adulthood. It is therefore critical to optimize neurocognitive outcomes of these youth. This review summarizes current understanding of the pathogenesis of HIV-associated CNS infection and the impact of cART on neurocognitive function in children and adolescents and discusses important areas for future research., (Copyright © 2014 John Wiley & Sons, Ltd.)

- Abstract
Objective: To evaluate prevalence, incidence, remission, and persistence of psychiatric and substance use disorders among HIV-infected mothers and identify biopsychosocial correlates., Methods: HIV-infected mothers (n = 1223) of HIV-exposed uninfected children enrolled in a prospective cohort study; HIV-uninfected mothers (n = 128) served as a comparison group. Mothers provided sociodemographic and health information and completed the Client Diagnostic Questionnaire (CDQ). Prevalence of any psychiatric or substance use disorder at initial evaluation was compared between the 2 groups. Incident, remitting, and persisting disorders were identified for 689 mothers with HIV who completed follow-up CDQs. We used logistic regression to evaluate adjusted associations of biopsychosocial characteristics with presence, incidence, remission, and persistence of disorders., Results: Thirty-five percent of mothers screened positive for any psychiatric or substance use disorder at initial evaluation, with no difference by maternal HIV status (P = 1.00). Among HIV-infected mothers, presence of any disorder was associated with younger age [adjusted odds ratio (aOR): 1.39; 95% CI: 1.09 to 1.75], single parenthood (aOR: 1.35; 95% CI: 1.08 to 1.68), and functional limitations (aOR: 2.29; 95% CI: 1.81 to 2.90). Incident disorders were associated with functional limitations (aOR: 1.92; 95% CI: 1.10 to 3.30). Among HIV-infected mothers with a disorder at initial evaluation (n = 238), 61% had persistent disorders. Persistent disorders were associated with lower income (aOR: 2.44; 95% CI: 1.33 to 4.76) and functional limitations (aOR: 3.19; 95% CI: 1.87 to 5.48). Receipt of treatment for any disorder was limited: 4.5% at study entry, 7% at follow-up, 5.5% at both entry and follow-up., Conclusions: Psychiatric and substance use disorders remain significant comorbid conditions among HIV-infected mothers and require accessible evidence-informed treatment.

- Abstract
Introduction: Across the globe, children born with perinatal HIV infection (PHIV) are reaching adolescence and young adulthood in large numbers. The majority of research has focused on biomedical outcomes yet there is increasing awareness that long-term survivors with PHIV are at high risk for mental health problems, given genetic, biomedical, familial and environmental risk. This article presents a review of the literature on the mental health functioning of perinatally HIV-infected (PHIV+) adolescents, corresponding risk and protective factors, treatment modalities and critical needs for future interventions and research., Methods: An extensive review of online databases was conducted. Articles including: (1) PHIV+ youth; (2) age 10 and older; (3) mental health outcomes; and (4) mental health treatment were reviewed. Of 93 articles identified, 38 met inclusion criteria, the vast majority from the United States and Europe., Results: These studies suggest that PHIV+ youth experience emotional and behavioural problems, including psychiatric disorders, at higher than expected rates, often exceeding those of the general population and other high-risk groups. Yet, the specific role of HIV per se remains unclear, as uninfected youth with HIV exposure or those living in HIV-affected households displayed similar prevalence rates in some studies, higher rates in others and lower rates in still others. Although studies are limited with mixed findings, this review indicates that child-health status, cognitive function, parental health and mental health, stressful life events and neighbourhood disorder have been associated with worse mental health outcomes, while parent-child involvement and communication, and peer, parent and teacher social support have been associated with better function. Few evidence-based interventions exist; CHAMP+, a mental health programme for PHIV+ youth, shows promise across cultures., Conclusions: This review highlights research limitations that preclude both conclusions and full understanding of aetiology. Conversely, these limitations present opportunities for future research. Many PHIV+ youth experience adequate mental health despite vulnerabilities. However, the focus of research to date highlights the identification of risks rather than positive attributes, which could inform preventive interventions. Development and evaluation of mental health interventions and preventions are urgently needed to optimize mental health, particularly for PHIV+ youth growing up in low-and-middle income countries.

- Abstract
Background: The influence of disease severity on cognitive and adaptive functioning in perinatally HIV-infected youth with (PHIV+/C) and without (PHIV+/NoC) a previous AIDS-defining illness (Centers for Disease Control and Prevention Class C event), compared with perinatally HIV-exposed but uninfected youth (PHEU) is not well understood., Methods: This was a cross-sectional analysis of cognitive and adaptive functioning in PHIV+/C (n = 88), PHIV+/NoC (n = 270) and PHEU (n = 200) youth aged 7-16 years, from a multisite prospective cohort study. Youth and caregivers completed the Wechsler Intelligence Scale for Children, Fourth Edition and the Adaptive Behavior Assessment System, Second Edition, respectively. We compared means and rates of impairment between groups, and examined associations with other psychosocial factors., Results: Overall mean scores on measures of cognitive and adaptive functioning were in the low average range for all 3 groups. After adjustment for covariates, mean full-scale intelligence quotient scores were significantly lower for the PHIV+/C group than the PHIV+/NoC and PHEU groups (mean = 77.8 versus 83.4 and 83.3, respectively), whereas no significant differences were observed between the PHEU and PHIV+/NoC groups in any domain. Lower cognitive performance for the PHIV+/C group was primarily attributable to a prior diagnosis of encephalopathy. No significant differences between groups were observed in adaptive functioning., Conclusion: For long-term survivors, youth with HIV infection and a prior Centers for Disease Control and Prevention Class C event have higher risk for cognitive but not adaptive impairment regardless of current health status; this finding appears attributable to a previous diagnosis of encephalopathy. Early preventive therapy may be critical in reducing risk of later neurodevelopmental impairments.

- Abstract
Mental health problems (MHPs) among children with perinatal HIV infection have been described prior to and during the highly active antiretroviral therapy (HAART) era. Yet child, caregiver and socio-demographic factors associated with MHPs are not fully understood. We examined the prevalence of MHPs among older children and adolescents with perinatal HIV exposure, including both perinatally HIV-infected (PHIV +) and perinatally HIV-exposed but uninfected (PHEU) youth. Our aims were to identify the impact of HIV infection by comparing PHIV + and PHEU youth and to delineate risk factors associated with MHPs, in order to inform development of appropriate prevention and intervention strategies. Youth and their caregivers were interviewed with the Behavior Assessment System for Children, 2nd edition (BASC-2) to estimate rates of at-risk and clinically significant MHPs, including caregiver-reported behavioral problems and youth-reported emotional problems. The prevalence of MHPs at the time of study entry was calculated for the group overall, as well as by HIV status and by demographic, child health, and caregiver characteristics. Logistic regression models were used to identify factors associated with youth MHPs. Among 416 youth enrolled between March 2007 and July 2009 (295 PHIV +, 121 PHEU), the overall prevalence of MHPs at entry was 29% and greater than expected based on recent national surveys of the general population. MHPs were more likely among PHEU than among PHIV + children (38% versus 25%, p < 0.01). Factors associated with higher odds of MHPs at p < 0.10 included caregiver characteristics (psychiatric disorder, limit-setting problems, health-related functional limitations) and child characteristics (younger age and lower IQ). These findings suggest that PHEU children are at high risk for MHPs, yet current models of care for these youth may not support early diagnosis and treatment. Family-based prevention and intervention programs for HIV affected youth and their caregivers may minimize long-term consequences of MHPs.

- Abstract
Background: Mitochondrial dysfunction has been associated with both human immunodeficiency virus (HIV) infection and exposure to antiretroviral therapy. Mitochondrial dysfunction has not been widely studied in HIV-infected children. We estimated the incidence of clinically defined mitochondrial dysfunction among children with perinatal HIV infection., Methods: Children with perinatal HIV infection enrolled in a prospective cohort study (Pediatric AIDS Clinical Trials Group protocols 219 and 219C) from 1993 through 2004 were included. Two clinical case definitions of mitochondrial dysfunction, the Enquête Périnatale Française criteria and the Mitochondrial Disease Classification criteria, were used to classify signs and symptoms that were consistent with possible mitochondrial dysfunction. Adjusted odds ratios of the associations between single and dual nucleoside reverse-transcriptase inhibitor use and possible mitochondrial dysfunction were estimated using logistic regression., Results: Overall, 982 (33.5%) of 2931 children met 1 or both case definitions of possible mitochondrial dysfunction. Mortality was highest among the 96 children who met both case definitions (20%). After adjusting for confounders, there was a higher risk of possible mitochondrial dysfunction among children who received stavudine regardless of exposure to other medications (odds ratio, 3.44 [95% confidence interval, 1.91-6.20]) or who received stavudine-didanosine combination therapy (odds ratio, 2.23 [95% confidence interval, 1.19-4.21]). Exposure to lamivudine and to lamivudine-stavudine were also associated with an increased risk of mitochondrial dysfunction., Conclusions: Receipt of nucleoside reverse-transcriptase inhibitors, especially stavudine and lamivudine, was associated with possible mitochondrial dysfunction in children with perinatal HIV infection. Further studies are warranted to elucidate potential mechanisms of nucleoside reverse-transcriptase inhibitor toxicities.

- Abstract
Objective: To examine the relationship between markers of vascular dysfunction and neurodevelopmental status in pediatric HIV disease., Design: A cross-sectional design within a prospective, 15-site cohort study conducted in the United States., Methods: Nine vascular biomarkers were examined in 89 HIV-infected children: soluble P-selectin/sCD62P, fibrinogen, adiponectin, monocyte chemoattractant protein-1/CCL-2, interleukin-6, C-reactive protein, soluble vascular cell adhesion molecule-1/sCD106, sE-selectin/sCD62E, and soluble intercellular adhesion molecule-1/sCD54. The Wechsler Intelligence Scale for Children-Fourth edition (WISC-IV) was administered yielding indices for verbal comprehension, perceptual reasoning, working memory and processing speed, and overall composite Full-Scale IQ score. Linear regression models were used to evaluate neurodevelopmental status (measured by WISC-IV scores) as a function of each biomarker while adjusting for demographics, disease severity, and receipt of HAART. Biomarker levels were evaluated in quartiles to evaluate trends in WISC-IV responses., Results: Among the 89 HIV-infected children (median age = 12 years), 56% were girls, 71% black, 16% Hispanic, and 43% had yearly household income below US $20,000. Log (soluble P-selectin) was significantly correlated with all WISC-IV scores; adjusted slopes showed 6-11-point average decrease in scores for each one log unit increase in soluble P-selectin. Final linear regression models for log (fibrinogen) adjusted for sociodemographic and disease characteristics also indicated a negative correlation with all WISC-IV scores (13-30-point decrease for each one log unit increase in fibrinogen); these decreases were significant in the verbal comprehension, perceptual reasoning, and Full-Scale IQ scores., Conclusion: Proinflammatory microvascular and immunologic mechanisms may be involved in neurodevelopmental impairment in children with perinatally acquired HIV disease.

- Abstract
Atrial natriuretic peptide (ANP) concentrations are typically elevated in hypervolemic states. However, ANP levels have been reported to be increased in the peripartum period in women with preeclampsia, a disorder characterized by central hypovolemia. We postulated that ANP levels are elevated in preeclamptic patients before clinically evident disease. ANP concentrations were determined in three groups: uncomplicated pregnancies, pregnancies complicated by preeclampsia, and non-pregnant reproductive-aged women. The former groups were matched for gestational age at plasma sampling and delivery. The plasma samples, obtained prospectively from each patient during the first, second, and third trimesters and within 72 h postpartum, were frozen before RIA. A significant gestational increase in ANP was noted in both groups of pregnant women, with third trimester levels exceeding first trimester levels (P less than 0.05). Consistent with previous reports, ANP levels were elevated in overtly preeclamptic patients vs. matched controls in the third trimester. The ANP concentration was also significantly increased during the second trimester in women destined to develop preeclampsia. Postpartum ANP values decreased in the preeclamptic group to approach the level in normal patients postpartum. Thus, it appears that the stimuli of ANP secretion differ in uncomplicated and preeclamptic patients. Moreover, an elevation of plasma ANP is detectable before the onset of clinical evidence of preeclampsia.
