Dahmani S, Rakhmanina N, Jiang X. Cognitive impairment in children and adolescents living with perinatal HIV disease in the ART era: a meta-analysis. EClinicalMedicine 2024; 72:102602. [PMID: 39010974 PMCID: PMC11247155 DOI: 10.1016/j.eclinm.2024.102602] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/01/2024] [Revised: 03/28/2024] [Accepted: 04/02/2024] [Indexed: 07/17/2024] Open
Abstract
Background Despite improved survival and overall health outcomes from modern antiretroviral therapy (ART), children and adolescents living with HIV are facing pervasive impairments in neurodevelopment including cognitive impairment, but there remains a lack of consensus on the cognitive domains that are affected in those children and adolescents. The objective of this meta-analysis was to evaluate the impact of perinatal HIV-infection on executive function, working memory, and speed of information processing in the ART era. Methods The PubMed database was searched for studies published between 1997 and 2024, plus additional search with the ScienceDirect, bioRxiv, and medRxiv databases. A meta-analysis was conducted on thirty-five studies published between 2012 and 2023 that encompassed a total of 4066 perinatally-infected HIV patients, 2349 HIV-exposed uninfected (HEU) controls, and 2466 HIV-unexposed, uninfected (HUU) controls. Performance scores on executive function, working memory, and processing speed were pooled using random-effects meta-analysis. Findings Compared to HEU and HUU controls, perinatally HIV-infected children and adolescents presented with significant impairments in processing speed (Hedges g = -0.64, p < 0.00001), working memory (Hedges g = -0.69, p < 0.00001), and to a lesser degree, executive function (Hedges g = -0.35, p = 0.02). Meta-regression analysis suggested that the effect estimate of processing speed impairment negatively correlated with Gross National Income (GNI) per capita of the study countries (CALHIV vs HUU, p = 0.0016; CALHIV vs HEU, p = 0.0019), even though HIV-infected cases were compared to sociodemographically matched HUU controls from the same countries. Sub-group meta-analyses with participants from high-income or low-/middle-income countries provided further evidence suggesting that the performance gap between HIV-infected cases and HUU/HEU controls may be larger in low-/middle-income countries than high-income countries. Interpretation In the ART era, cognitive impairment (especially reduced processing speed and working memory) persists in children and adolescents living with HIV. These impairments may be more pronounced among those children and adolescents living with HIV in low-income countries, suggesting that there may be global health inequities in treatment outcomes with perinatal HIV-infection. However, meta-analysis and meta-regression analysis have their limitations, which calls for future collaborative multi-country international studies to directly investigate this important topic. Nevertheless, there is an unmet need to assure equity in timely assessments and interventions to optimize neurocognitive development and outcomes among children and adolescents with perinatal HIV globally. Funding This research was supported in part by NIH R01MH108466, NIH R56NS124422, and NIH R01NS124422.

The adolescent HIV executive function and drumming (AHEAD) study, a feasibility trial of a group drumming intervention amongst adolescents with HIV. AIDS Care 2023; 35:1796-1814. [PMID: 37039077 DOI: 10.1080/09540121.2023.2195607] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2022] [Accepted: 03/20/2023] [Indexed: 04/12/2023]
Abstract
AHEAD feasibility trial assessed the feasibility and acceptability of an 8-session group drumming programme aiming to improve executive function, depression and anxiety symptoms, and perceived social support in adolescents living with HIV in a rural low-income South African setting. Sixty-eight 12- to 19-year-old adolescents participated. They were individually randomised. The intervention arm (n = 34) received weekly hour-long group drumming sessions. Controls (n = 34) received no intervention. Feasibility and acceptability were assessed using rates of: enrolment; retention; attendance; logistical problems; adolescent-reported acceptability. Secondary measures included: five Oxford Cognitive Screen-Executive Function (OCS-EF) tasks; two Rapid Assessment of Cognitive and Emotional Regulation (RACER) tasks; the Self-Reporting Questionnaire-20 (SRQ-20) measuring depression and anxiety symptoms; the Multidimensional Scale of Perceived Social Support (MSPSS). All feasibility criteria were within green progression limits. Enrolment, retention, and acceptability were high. There was a positive effect on adolescent depressed mood with signal for a working memory effect. There were no significant effects on executive function or socio-emotional scales. Qualitative findings suggested socio-emotional benefits including: group belonging; decreased internalised stigma; improved mood; decreased anxiety. Group drumming is a feasible and acceptable intervention amongst adolescents living with HIV in rural South Africa. A full-scale trial is recommended.

Abstract
The objective of this study was to validate the NIH Toolbox Cognition Battery (NIHTB-CB) in Zambian children with and without HIV-infection. Children living with HIV and HIV-exposed, uninfected (HEU) children completed traditional neuropsychological and NIHTB-CB tasks. Using pairwise correlation and a linear regression model we measured associations between traditional measure composite scores and parental ratings of children's abilities, and NIHTB-CB scores. A Receiver Operating Characteristic (ROC) curve was developed to identify participants with impairment. 389 children, 8-17 years old participated. NIHTB-CB and traditional measures converged well as a whole and when comparing analogous individual tests across the two batteries. The NIHTB-CB composite score discriminated between the groups and was positively associated with external criteria for cognitive function: parental ratings of intelligence and school performance. Some English vocabulary and/or an unfamiliar cultural context presented challenges. NIHTB-CB was associated with children's everyday cognitive abilities, though future use may require linguistic and cultural adaptation.

Abstract
BACKGROUND Worldwide, there are more than 13.3 million orphans and vulnerable children affected by Human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) (HIV OVC), defined as individuals below the age of 18 who have lost one or both parents to HIV/AIDS or have been made vulnerable by HIV/AIDS; they are at risk for negative psychosocial and cognitive outcomes. PURPOSE This meta-analysis aimed to examine the scientific literature on available interventions for HIV OVC, with a focus on community-based interventions (CBI). METHODS Systematic electronic searches were conducted from four databases between October 2016 and April 2017 to identify articles investigating the effectiveness of interventions for HIV OVC. Effect sizes were calculated for each article which provided enough information and data points for analyses. RESULTS Seventy-four articles were reviewed, including psychosocial interventions (d = 0.30), cognitive interventions (d = 0.14), social protection interventions (d = 0.36), and community-based interventions (CBI; d = 0.36). Study-specific effect sizes varied widely, ranging from -1.09 to 2.26, that is, from a negative effect to an impressively large positive one, but the majority of studies registered small to medium effects (the overall effect size for all studies was 0.32, SE = 0.03, 95% CI: 0.26-0.37). Social protection interventions had the highest positive outcomes whereas CBI tended to have the fewest significant positive outcomes, with some outcomes worsening instead of improving. CONCLUSIONS Overall, interventions provided to OVC have potential for improving cognitive, psychosocial, and risk-behavior outcomes. Social protection interventions and CBI had the highest effect sizes, but CBI had positive effects on fewer outcomes and demonstrated some negative effects. CBI warrant scrutiny for improvement, as they represent an important form of culturally embedded services with potentially long-term benefits to OVC, yet appear to be differentially effective. Successful components of other types of intervention were identified, including cash grants, mentorship, and family therapy. In addition, more research is needed that attends to which interventions may be more effective for specific populations, or that studies cost-effectiveness.

Abstract
BACKGROUND Youth with perinatal HIV exposure have demonstrated high rates of emotional-behavioral problems. Few studies have longitudinally examined racial/ethnic disparities in such functioning across adolescence, a critical time for targeting prevention/intervention efforts. SETTING The Pediatric HIV/AIDS Cohort Study Adolescent Master Protocol is one of the largest US-based cohort studies of youth with perinatal HIV (YPHIV) infection or HIV exposed but uninfected (YPHEU). METHODS Youth and caregivers individually completed the Behavior Assessment System for Children, second edition, every 2 years between ages 7 and 19 years. We used adjusted mixed-effects models to evaluate whether mean youth-reported emotional concerns and caregiver-reported behavioral concerns differed by race/ethnicity. We used group-based trajectory models to identify groups having similar emotional-behavioral trajectories, followed by multinomial models to determine which factors predicted group membership. RESULTS Three hundred ninety-one YPHIV and 209 YPHEU (7% White non-Hispanic, 21% White Hispanic, 66% Black non-Hispanic, and 6% Black Hispanic) completed a median of 4 assessments over follow-up. Adjusted models showed more caregiver-reported behavioral concerns for Black non-Hispanic YPHEU than for Black non-Hispanic YPHIV, White Hispanic YPHIV, and White Hispanic YPHEU, particularly later in adolescence. Race/ethnicity did not predict membership in subgroups of youth-reported emotional or caregiver-reported behavioral functioning identified using group-based trajectory models. However, factors predicting membership in vulnerable youth-reported emotional and caregiver-reported behavioral groups included experiencing a stressful life event and living with a caregiver who was married or screened positive for a psychiatric condition. CONCLUSIONS Our study revealed that Black non-Hispanic YPHEU are a vulnerable subgroup. Contributing factors that could inform interventions include the caregiver's health, household characteristics, and psychiatric status.

Abstract
Adolescents and youth living with HIV have poorer antiretroviral treatment (ART) adherence and viral suppression outcomes than all other age groups. Effective interventions promoting adherence are urgently needed. We reviewed and synthesized recent literature on interventions to improve ART adherence among this vulnerable population. We focus on studies conducted in low- and middle-income countries (LMIC) where the adolescent and youth HIV burden is greatest. Articles published between September 2015 and January 2019 were identified through PubMed. Inclusion criteria were: [1] included participants ages 10-24 years; [2] assessed the efficacy of an intervention to improve ART adherence; [3] reported an ART adherence measurement or viral load; [4] conducted in a LMIC. Articles were reviewed for study population characteristics, intervention type, study design, outcomes measured, and intervention effect. Strength of each study's evidence was evaluated according to an adapted World Health Organization GRADE system. Articles meeting all inclusion criteria except being conducted in an LMIC were reviewed for results and potential transportability to a LMIC setting. Of 108 articles identified, 7 met criteria for inclusion. Three evaluated patient-level interventions and four evaluated health services interventions. Of the patient-level interventions, two were experimental designs and one was a retrospective cohort study. None of these interventions improved ART adherence or viral suppression. Of the four health services interventions, two targeted stable patients and reduced the amount of time spent in the clinic or grouped patients together for bi-monthly meetings, and two targeted patients newly diagnosed with HIV or not yet deemed clinically stable and augmented clinical care with home-based case-management. The two studies targeting stable patients used retrospective cohort designs and found that adolescents and youth were less likely to maintain viral suppression than children or adults. The two studies targeting patients not yet deemed clinically stable included one experimental and one retrospective cohort design and showed improved ART adherence and viral suppression outcomes. ART adherence and viral suppression outcomes remain a major challenge among adolescents and youth. Intensive home-based case management models of care hold promise for improving outcomes in this population and warrant further research.

Abstract
Orphans and vulnerable children affected by HIV/AIDS (HIV OVC) are at risk for cognitive difficulties and lack of access to education. Interventions addressing cognitive or educational outcomes for HIV OVC worldwide were examined through systematic searches conducted from October 2016 to 2019. We examined the summative effectiveness of interventions and the specific effects of participant age and intervention length. Interventions targeting cognitive outcomes had a small, significant effect, with no effect of moderating variables. Interventions targeting educational outcomes had significant effects. Educational interventions over 1 year were effective, but effects of intervention length were not significant. Overall, this review provides support for the effectiveness of interventions targeting cognitive and educational outcomes for OVC and highlights the need for more research on such interventions.

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
OBJECTIVES To assess longitudinal patterns and determinants of cognitive development in infants living with HIV, infants exposed to maternal HIV infection, and HIV-unexposed infants. METHODS Prospective, community-based cohort study of 555 Malawian infants aged 8 weeks to 24 months, using multivariable linear mixed-effects regression models with random intercepts to analyze repeated measures of cognitive function. RESULTS At 3 months of age, cognitive scores on the Bayley Scales of Infant Development (BSID 3rd edition) were lower in the 96 HIV-infected infants (mean = 14.1 (SD:4.8)) compared to the 289 HIV-exposed (mean = 16.5 (SD:3.7)) and the 170 unexposed infants (mean = 17.5 (SD:3.3)). Over the first two years of life, the small deficit in cognitive development of infants living with HIV who survived and remained in care did not increase (mean score 52.9 among HIV-infected vs 55.6 among HIV unexposed). In multivariable analysis, malnutrition and a more advanced clinical infant HIV stage had a negative impact on cognition at age 3, while financial security, care by the biological mother, and ART for mother and child were associated with better cognitive status at this young age. The positive influence of maternal ART reversed with age. CONCLUSIONS Malawian infants exposed to HIV had a cognitive development that was similar to their unexposed peers in the first two years of life, while that of HIV infected infants lagged behind from the start. Early initiation of effective ART in all HIV infected mothers and infants, and prevention of infant malnutrition are important to safeguard cognitive development of children affected by HIV.

Abstract
BACKGROUND Children with perinatal HIV (pHIV) may display distinct long-term cognitive phenotypes. We used group-based trajectory modeling to identify clusters of children with pHIV after similar developmental trajectories and predictors of belonging to select cognitive trajectory groups. METHODS Participants included children, 4-17 years of age, with pHIV in Thailand and Cambodia. Cognitive measures included translated versions of Intelligence Quotient tests, Color Trails Tests and Beery-Buktenica Developmental Test of Visual-Motor Integration conducted semiannually over 3-6 years. The best fit of trajectory groups was determined using maximum likelihood estimation. Multivariate logistic regression identified baseline factors associated with belonging to the lowest scoring trajectory group. RESULTS Group-based trajectory analyses revealed a 3-cluster classification for each cognitive test, labeled as high, medium and low scoring groups. Most trajectory group scores remained stable across age. Verbal IQ declined in all 3 trajectory groups and the high scoring group for Children's Color Trails Test 1 and 2 showed an increase in scores across age. Children in the lowest scoring trajectory group were more likely to present at an older age and report lower household income. CONCLUSIONS Group-based trajectory modeling succinctly classifies cohort heterogeneity in cognitive outcomes in pHIV. Most trajectories remained stable across age suggesting that cognitive potential is likely determined at an early age with the exception of a small subgroup of children who displayed developmental gains in select cognitive domains and may represent those with better cognitive reserve. Poverty and longer duration of untreated HIV may predispose children with pHIV to suboptimal cognitive development.

The global epidemiology of adolescents living with HIV: time for more granular data to improve adolescent health outcomes. Curr Opin HIV AIDS 2019; 13:170-178.

Abstract
PURPOSE OF REVIEW The aim of this study was to summarize recent evidence on the global epidemiology of adolescents (age 10-19 years) living with HIV (ALHIV), the burden of HIV on the health of adolescents and HIV-associated mortality. RECENT FINDINGS In 2016, there were an estimated 2.1 million (uncertainty bound 1.4-2.7 million) ALHIV; 770 000 younger (age 10-14 years) and 1.03 million older (age 15-19 years) ALHIV, 84% living in sub-Saharan Africa. The population of ALHIV is increasing, as more peri/postnatally infected ALHIV survive into older ages; an estimated 35% of older female ALHIV were peri/postnatally infected, compared with 57% of older male ALHIV. Although the numbers of younger ALHIV deaths are declining, deaths among older ALHIV have remained static since peaking in 2012. In 2015, HIV-associated mortality was the eighth leading cause of adolescent death globally and the fourth leading cause in African low and middle-income countries. SUMMARY Needed investments into characterizing and improving adolescent HIV-related health outcomes include strengthening systems for nationally and globally disaggregated data by age, sex and mode of infection; collecting more granular data within routine programmes to identify structural, social and mental health challenges to accessing testing and care; and prioritizing viral load monitoring and adolescent-focused differentiated models of care.

Abstract
PURPOSE OF REVIEW Adolescents with HIV include both those infected perinatally and behaviourally. This population is confronted by normative challenges and HIV stressors as they move towards becoming increasingly independent adults. This review focuses on mental health and substance use in adolescents with HIV. These are important issues in their own right as well as having implications for antiretroviral therapy (ART) adherence and HIV management. RECENT FINDINGS Sixteen articles, published from 1 January 2016 to 1 September 2017, were included from 13 distinct studies, mostly from the United States and Africa. Cross-sectional designs predominated. There was only one intervention study. There was evidence of mental health and substance use difficulties, although not at a higher level than comparison groups. Consistent associations were found between ART nonadherence and both mental health difficulties and substance use; environmental stressors and mental health difficulties. SUMMARY Adolescents with HIV display considerable resilience. There is a need, however, for interventions for mental health difficulties and substance use, and for ART adherence interventions to consider these issues. Studies on mental health and substance use should cover a wider range of regions. Mitigating the impact and reducing exposure to environmental stressors is a priority.

Agreement and Discrepancy on Emotional and Behavioral Problems Between Caregivers and HIV-Infected Children and Adolescents From Uganda. Front Psychiatry 2019; 10:460. [PMID: 31354539 PMCID: PMC6637279 DOI: 10.3389/fpsyt.2019.00460] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2018] [Accepted: 06/11/2019] [Indexed: 01/14/2023] Open
Abstract
Background: HIV-infected children and adolescents (CA-HIV) face significant mental health challenges related to a broad range of biological and psychosocial factors. Data are scarce on the agreement and discrepancy between caregivers and CA-HIV regarding emotional and behavioral problems (EBPs) in CA-HIV. Objectives: We determined agreement between self- versus caregiver- reported EBPs and describe factors associated with informant discrepancy among caregiver-youth dyads who participated in the "Mental health among HIV-infected CHildren and Adolescents in KAmpala and Masaka, Uganda" (CHAKA) study. Methods: In a cross-sectional sample, caregiver-reported EBPs were assessed with the Child and Adolescent Symptom Inventory-5 (CASI-5), and self-reported problems were evaluated with the Youth Inventory-4 (YI-4) in 469 adolescents aged 12-17 years and the Child Inventory-4 (CI-4) in 493 children aged 8-11 years. Adolescents were questioned about experiences of HIV stigma. Caregiver psychological distress was assessed with the Self-Reporting Questionnaire (SRQ-20). Linear regression models were applied to identify variables associated with discrepancy scores. Results: Self-reported emotional problems (EPs) were present in 28.8% of adolescents and 36.9% of children, and 14.5% of adolescents self-reported behavioral problems (BPs). There was only a modest correlation (r ≤ 0.29) between caregiver- and CA-HIV-reported EBPs, with caregivers reporting more EPs whereas adolescents reported more BPs. Informant discrepancy between adolescents and caregivers for BPs was associated with adolescent age and caregiver's employment and HIV status. Among adolescents, EP discrepancy scores were associated with adolescent's WHO HIV clinical stage, caregiver level of education, and caregivers caring for other children. Among children, EP discrepancy scores were associated with child and caregiver age, caregiver level of education, and caregiver self-rated health status. HIV stigma and caregiver psychological distress were also associated with discrepancy, such that adolescents who experienced HIV stigma rated their EPs as more severe than their caregivers did and caregivers with increased psychological distress rated EBPs as more severe than CA-HIV self-rated. Conclusions: EBPs are frequently endorsed by CA-HIV, and agreement between informants is modest. Informant discrepancy is related to unique psychosocial and HIV-related factors. Multi-informant reports enhance the evaluation of CA-HIV and informant discrepancies can provide additional insights into the mental health of CA-HIV.

Abstract
We examined the role of youth HIV status and other key factors on past-year arrest in perinatally HIV-exposed but uninfected (PHIV-) and perinatally HIV-infected (PHIV+) youth using data from a multi-site study of psychosocial behaviors in PHIV-exposed urban youth (N = 340; 61% PHIV+; 51% female; ages 9-16 at baseline). Youth and caregivers were administered 5 interviews, spanning approximately 7.5 years. Using longitudinal logistic mixed-effect models, we explored the association between past year arrest, internal [e.g., substance use disorder (SUD)] and external (e.g., neighborhood arrest rates) contextual factors, and social-regulation processes (e.g., in-school/work). Arrest rates increased from 2.6 to 19.7% across follow-ups; there were no differences in arrest over time by HIV status. In the final model, odds of arrest were greater for youth who were male, with SUD, ≥ 18 years old, with high levels of city stress, and neither in school nor employed. PHIV-exposed, urban youth have much higher rates of arrest than national samples. Lack of differences in arrest by HIV status suggests key contextual factors are more important in promoting arrest.

Abstract
BACKGROUND Little is known of mental health outcomes among vertically HIV-infected or HIV-affected adolescents in Africa. OBJECTIVES The current study set out to describe depressive symptoms and their correlates among vertically HIV-infected and HIV-affected adolescents at the Kenyan Coast. METHODS 130 adolescents (vertically HIV-infected [n = 44], HIV-affected [n = 53], and unexposed [n = 33]) and their caregivers participated in this cross-sectional study. An adapted version of the Beck Depression Inventory-11 (BDI) was administered to examine depressive symptoms in both adolescents and caregivers, together with measures of sociodemographic, medical, and anthropometric characteristics. FINDINGS Our analysis indicated a main effect of HIV status on mean BDI scores in HIV-infected (18.4 [SD = 8.3) and HIV-affected (16.8 [SD = 7.3]) adolescents compared to the community controls (12.0 [SD = 7.9]), F (2, 127) = 6.704, P = .002, η2 = .095. Post hoc analysis showed that BDI scores of HIV-infected adolescents were higher than those of community controls (P < .001). Similarly, HIV-affected adolescents had BDI scores that were higher than those of community controls (P = .007). However, there was no difference in BDI scores between HIV-infected and HIV-affected adolescents (P = .304). A path analytic model indicated that cumulative psychosocial risk (orphanhood, family poverty, and caregiver depressive symptoms) were positive predictors of BDI scores among adolescents, while nutritional status had a limited role. CONCLUSIONS Both HIV-infected and HIV-affected adolescents are at a high risk of experiencing depressive symptoms, largely due to the multiple psychosocial risk factors in their environment. The provision of adequate psychosocial support and counseling needs to become an integral part of the care program for adolescents from families living with HIV/AIDS at the Kenyan coast and other similar settings.

Abstract
Accurate assessment of HIV-associated cognitive disorders in perinatally infected children and adolescents is challenging. Assessments of general intellectual functioning, or global cognition, may not provide information regarding domain-specific strengths and weaknesses, and may therefore fail to detect, impaired trajectories of development within particular cognitive domains. We compare the efficacy of global cognitive scores to that of composite cognitive domain scores in detecting cognitive disorders in a sample of perinatally HIV-infected children, and a demographically matched HIV negative control group, drawn from the Cape Town Adolescent Antiretroviral Cohort (CTAAC) study. All children were administered a comprehensive neuropsychological test battery. Using data from that test battery, we created ten separate composite cognitive domains: general intellectual functioning, attention, working memory, visual memory, verbal memory, language, visual spatial ability, motor coordination, processing speed and executive function. Within each domain, each test bore a high level of association with each of the other tests in that domain (Cronbach's α ≥ .70 for all domains). We found that composite domain scores calculated on whole-sample data were significantly higher than those calculated using control-sample data. Our comparison of a global cognitive score to composite domain scores suggested that the latter provided more detailed information (regarding strengths, weaknesses, areas of impairment), and when compared to global scores, were more sensitive in detecting HIV-associated cognitive disorders, and were able to distinguish HIV-infected patients from uninfected controls. Hence, we recommend using this method of composite cognitive domains scores, rather than global aggregate scores, when assessing cognitive function in paediatric HIV. This method provides a convenient and relatively accurate assessment that might help with cross-cultural and cross-region comparisons as researchers try to detect cognitive impairment patterns in HIV-infected children and adolescents globally.

Impact of Perinatally Acquired HIV Disease Upon Longitudinal Changes in Memory and Executive Functioning. J Acquir Immune Defic Syndr 2017; 75:455-464.

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.
