Abstract
Central nervous system involvement in HIV infection leads to neurobehavioural sequelae. Although apathy is a well-recognised symptom in adults living with HIV linked to alterations in brain structure, there is scarce research examining motivation in children living with HIV (CLWH). We used the Children's Motivation Scale (CMS; normative mean = 50, SD = 10) to assess motivation levels in 76 CLWH aged 6-16 years (63 on antiretroviral therapy [ART]; 13 ART-naïve slow progressors) in South Africa. Overall, CLWH scored low on the CMS (mean = 35.70 [SD = 5.87]). Motivation levels were significantly reduced in children taking ART compared to ART-naïve slow progressors (p = 0.02), but were not correlated with markers of HIV disease (CD4 + cell count or viral load), or neurocognitive function (p > 0.05). CMS scores were correlated with diffusion tensor imaging metrics of white matter microstructure in specific frontostriatal brain regions (p < 0.05). On multiple regression, associations with the anterior limb of the internal capsule, a subcortical white matter region, remained significant after adjusting for potential confounders. These findings suggest that reduced motivation may be an important neurobehavioural symptom in CLWH and may reflect changes in white matter microstructure of frontostriatal brain regions.

Central auditory test performance predicts future neurocognitive function in children living with and without HIV. Sci Rep 2024; 14:2712.

Abstract
Tests of the brain's ability to process complex sounds (central auditory tests) correlate with overall measures of neurocognitive performance. In the low- middle-income countries where resources to conduct detailed cognitive testing is limited, tests that assess the central auditory system may provide a novel and useful way to track neurocognitive performance. This could be particularly useful for children living with HIV (CLWH). To evaluate this, we administered central auditory tests to CLWH and children living without HIV and examined whether central auditory tests given early in a child's life could predict later neurocognitive performance. We used a machine learning technique to incorporate factors known to affect performance on neurocognitive tests, such as education. The results show that central auditory tests are useful predictors of neurocognitive performance and perform as well or in some cases better than factors such as education. Central auditory tests may offer an objective way to track neurocognitive performance in CLWH.

Abstract
Perinatal HIV impacts on growth and development in childhood, with physical impairments such as growth limitations, decreased physical activity, reduced exercise tolerance and cardiopulmonary dysfunction continuing into adolescence. There is limited data on other physical functioning domains in perinatally HIV-infected adolescents (PHIVA) thus the aim of this study was to establish the physical sequelae of perinatal HIV in adolescents. This South African cross-sectional study compared PHIVA with HIV-negative adolescents, assessing anthropometry, muscle strength, endurance and motor performance. All ethical considerations were adhered to. The study included 147 PHIVA and 102 HIV-negative adolescents, aged 10-16 years. The majority (87.1%) of PHIVA were virally suppressed however, they still showed significant deficits in height (p < 0.001), weight (p < 0.001) and BMI (p = 0.004). Both groups performed poorly in muscle strength and endurance but did not differ significantly. In motor performance, the PHIVA scored significantly lower for manual dexterity and balance, with significantly more PHIVA with motor difficulty. A regression analysis showed that viral suppression predicted muscle strength (p = 0.032) and age positively predicted endurance (p = 0.044) and negatively predicated aiming and catching (p = 0.009). In conclusion, PHIVA face growth deficits and challenges with motor performance, especially with manual dexterity and balance.

Abstract
INTRODUCTION Peer support can help navigate the isolation and psychological strain frequently experienced by youth living with chronic illness. Yet, data are lacking on the impact of providing support for youth living with mixed chronic conditions. We assessed the acceptability, feasibility and preliminary mental health impacts of a clinic-based peer support group for South African youth living with chronic illnesses, including HIV. METHODS This mixed-methods pilot study (September 2021-June 2022) enrolled 58 young patients, ages 13-24, at an urban hospital in Cape Town, South Africa. In-depth interviews elicited the perspectives of 20 young people in relation to their participation in the Better Together programme, a recurring clinic-based peer support group for patients with mixed chronic illnesses. Self-reported resilience, attitudes towards illness, stigma and mental health were captured via established measures. T-tests and multivariate analysis of variance compared psychosocial outcomes for 20 group participants and 38 control patients, controlling for socio-demographic characteristics at enrolment. Logistic regression analyses estimated the predicted probability of a positive depression or anxiety screening given peer group participation. RESULTS All interviewees valued being able to compare treatment regimens and disease management habits with peers living with different conditions. Adolescents living with HIV stated that understanding the hardships faced by those with other conditions helped them accept their own illness and lessened feelings of isolation. Compared to patients who did not participate in Better Together, those who attended ≥5 groups had statistically significantly higher individual-level resilience, a more positive attitude towards their illness(es), lower internalised stigma and a more positive self-concept. The probability of being screened positive for depression was 23.4 percentage points lower (95% CI: 1.5, 45.3) for Better Together participants compared to controls; the probability of a positive anxiety screening was 45.8 percentage points lower (95% CI: 18.1, 73.6). CONCLUSIONS Recurring, clinic-based peer support groups that integrate youth living with HIV and other chronic diseases are novel. Group sustainability will depend on the commitment of experienced peer leaders and providers, routine scheduling and transportation support. A fully powered randomised trial is needed to test the optimal implementation and causal mental health effects of the Better Together model.

Abstract
The management of adolescents living with HIV represents a particular challenge in the global response to HIV. The challenges specific to this age group include difficulties engaging and maintaining them in care, challenges with transition to adult care, and limited therapeutic options for treatment-experienced patients, all of which have been jeopardized by the COVID-19 pandemic. This paper summarizes some of the challenges in managing adolescents living with HIV, as well as some of the most recent and innovative therapeutic approaches in this population.

Abstract
Host genetic factors may modify the risk of developing HIV-associated neurocognitive impairment (HIV-NCI), and genetic research has the potential to inform novel treatments for HIV-NCI. However, there is a need to better understand the acceptability of genetic testing among distinct populations of people living with HIV at increased risk for HIV-NCI, such as young people living with perinatally acquired HIV (PHIV) in low- and middle-income countries, to gauge the feasibility of genetic research within these populations. This pilot study evaluated the acceptability and feasibility of genetic testing to assess risk of future neurocognitive problems in 50 Thai adolescents and young adults (13-24 years; Meanage = 19.16 [standard deviation = 3.09]; 52% female) with PHIV and demographically similar HIV-negative controls. Participants (25 PHIV; 25 controls) completed a survey assessing acceptability of and concerns about genetic testing and were asked to provide blood samples for genetic testing. Descriptive statistics and blood draw completion rates were produced and calculated. Reported concerns about genetic testing were grouped thematically and tallied. Independent t tests and chi-squares explored demographic differences between participants who reported concerns and peers. Results indicated 46 participants (92%) rated genetic testing as "acceptable" or "completely acceptable." Eight participants (16%) reported concerns about genetic testing. The most common concerns were related to genetic information being shared or misused. Compared with participants without concerns, participants who reported concerns had more years of education and were more likely to have postsecondary schooling. Regarding completion rates, 49 participants (98%) agreed to genetic testing and provided blood samples. Overall, results support the acceptability and feasibility of incorporating genetic testing into research investigating HIV-NCI among adolescents and young adults in Thailand. Findings provide important considerations for planning future genetic studies among young people in Thailand.

Abstract
BACKGROUND Early antiretroviral therapy (ART) during infancy reduces cognitive impairment due to HIV, but the extent of benefit is unclear. SETTING Children were recruited from hospital and health centers providing HIV care and treatment in Nairobi, Kenya. METHODS Cognitive, behavioral, and motor outcomes were assessed in children with HIV and early ART (<1 year), children with HIV and late ART (1.5-6 years), and children HIV-unexposed uninfected (CHUU). Domain z scores and odds neurobehavioral impairment (≤15th percentile in CHUU) were compared in adjusted analyses. RESULTS Children with HIV initiated ART at median ages 0.4 (early ART) and 3.5 years (late ART). Children were assessed at median ages 6.9 (CHUU, N = 61), 6.9 (early ART, N = 54), and 13.5 (late ART; N = 27) years. Children with late ART vs. children with early ART had significantly lower z scores in 7 domains, specifically global cognition, short-term memory, visuospatial processing, learning, nonverbal test performance, executive function, and motor skills (adjusted mean differences, -0.42 to -0.62, P values ≤ 0.05), and had higher odds impairment in 7 domains (adjusted odds ratios [aORs], 2.87 to 16.22, P values ≤ 0.05). Children with early ART vs. CHUU had lower z scores in 5 domains (global cognition, short-term memory, delayed memory, processing speed, and behavioral regulation [adjusted mean differences, -0.32 to -0.88, P values < 0.05]) and higher impairment for 2 domains (short-term memory [aOR, 3.88] and behavioral regulation [aOR 3.46], P values < 0.05). Children with late ART vs. CHUU had lower z scores in 8 domains (adjusted mean differences, -0.57 to -1.05, P values ≤ 0.05), and higher impairment in 7 domains (aORs 1.98 to 2.32, P values ≤ 0.05). CONCLUSION Early ART in the first year of life attenuates but does not eliminate the neurodevelopmental compromise of HIV.

Similar cortical morphometry trajectories from 5 to 9 years in children with perinatal HIV who started treatment before age 2 years and uninfected controls. BMC Neurosci 2023; 24:15.

Abstract
BACKGROUND Life-long early ART (started before age 2 years), often with periods of treatment interruption, is now the standard of care in pediatric HIV infection. Although cross-sectional studies have investigated HIV-related differences in cortical morphology in the setting of early ART and ART interruption, the long-term impact on cortical developmental trajectories is unclear. This study compares the longitudinal trajectories of cortical thickness and folding (gyrification) from age 5 to 9 years in a subset of children perinatally infected with HIV (CPHIV) from the Children with HIV Early antiRetroviral therapy (CHER) trial to age-matched children without HIV infection. METHODS 75 CHER participants in follow-up care at FAMCRU (Family Centre for Research with Ubuntu), as well as 66 age-matched controls, received magnetic resonance imaging (MRI) on a 3 T Siemens Allegra at ages 5, 7 and/or 9 years. MR images were processed, and cortical surfaces reconstructed using the FreeSurfer longitudinal processing stream. Vertex-wise linear mixed effects (LME) analyses were performed across the whole brain to compare the means and linear rates of change of cortical thickness and gyrification from 5 to 9 years between CPHIV and controls, as well as to examine effects of ART interruption. RESULTS Children without HIV demonstrated generalized cortical thinning from 5 to 9 years, with the rate of thinning varying by region, as well as regional age-related gyrification increases. Overall, the means and developmental trajectories of cortical thickness and gyrification were similar in CPHIV. However, at an uncorrected p < 0.005, 6 regions were identified where the cortex of CPHIV was thicker than in uninfected children, namely bilateral insula, left supramarginal, lateral orbitofrontal and superior temporal, and right medial superior frontal regions. Planned ART interruption did not affect development of cortical morphometry. CONCLUSIONS Although our results suggest that normal development of cortical morphometry between the ages of 5 and 9 years is preserved in CPHIV who started ART early, these findings require further confirmation with longitudinal follow-up through the vulnerable adolescent period.

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).

Longitudinal Cognitive Outcomes in Children With HIV in Zambia: 2-Year Outcomes From the HIV-Associated Neurocognitive Disorders in Zambia (HANDZ) Study. J Acquir Immune Defic Syndr 2022; 91:217-225.

Abstract
OBJECTIVE To describe longitudinal outcomes and predictors of cognitive outcomes in children with HIV in Zambia. BACKGROUND Multiple studies have shown that children with HIV are at risk for impaired cognition. However, there are limited data on longitudinal cognitive outcomes in children with HIV. METHODS We conducted a prospective cohort study of 208 perinatally infected children with HIV ages 8-17 years, all treated with antiretroviral therapy, and 208 HIV-exposed uninfected controls. Participants were followed for 2 years. Cognition was assessed with a custom NIH Toolbox Cognition Battery, and tests were combined to generate a Summary Cognition Score (SCS). The contribution of potential risk factors to outcomes was explored using regression models and group-based trajectory modeling. RESULTS HIV was strongly associated with lower SCS at baseline [β-14, 95% confidence interval (CI): -20 to -7, P < 0.001]. Change scores over time were similar between groups, but poorer average performance in children with HIV persisted at the 2-year follow-up visit (adjusted β = -11, 95% CI: -22 to -0.3, P = 0.04). Other than HIV, the strongest predictors of baseline SCS included socioeconomic status index (β =3, 95% CI: 1, 5, P = 0.004), history of growth stunting (β=-14, 95% CI: -23 to -6, P = 0.001), history of CD4 count below 200 (β = -19, 95% CI: -35 to -2, P = 0.02), and history of World Health Organization stage 4 disease (β = -10, 95% CI: -19 to -0.2, P = 0.04). In the group-based trajectory model, HIV+ status predicted membership in the lowest performing trajectory group (odds ratio 2.5, 95% CI: 1.2 to 5.1, P = 0.01). CONCLUSIONS Children with HIV are at risk of poor cognitive outcomes, despite chronic treatment with antiretroviral therapy.

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.

Ageing with HIV: a longitudinal study of markers of resilience in young adults with perinatal exposure to HIV, with or without perinatally acquired HIV. J Int AIDS Soc 2022; 25 Suppl 4:e25982. [PMID: 36176020 PMCID: PMC9522985 DOI: 10.1002/jia2.25982] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2022] [Accepted: 08/01/2022] [Indexed: 12/29/2022] Open
Abstract
INTRODUCTION Medical challenges, including perinatally acquired HIV (PHIV), can be considered adversity with the potential to compromise individuals' ability to meet societal expectations across the lifespan. Studies suggest that resilience, defined as positive adaptation in the context of adversity, helps individuals overcome challenges and improve their quality of life. Few longitudinal studies have examined resilience in young adults with perinatally acquired HIV (YAPHIV) or perinatal HIV exposure, uninfected (YAPHEU). We examined three young adult milestones, which can affect the life-long quality of life, as markers of resilience: high school graduation, postsecondary education and current employment. METHODS Analyses included YAPHIV and YAPHEU, ages 19-27 years, followed in longitudinal cohort studies: Pediatric HIV/AIDS Cohort Study Adolescent Master Protocol (AMP) (7-17 years) and AMP Up (≥18 years). Factors known to influence the attainment of milestones (outcomes) were examined: executive function, cognitive efficiency (working memory and processing speed), behavioural/social-emotional functioning, parent/caregiver mental/physical health and cumulative risk. HIV disease markers for YAPHIV were examined. The most recent AMP assessment was used for each factor; outcomes were measured at AMP Up 1-year follow-up. Separate robust Poisson regression models were used to assess associations of each factor with each outcome; PHIV status was explored as an effect modifier of each association. RESULTS Participants (N = 315; YAPHIV = 228): 58% female, 67% Black and 27% Hispanic. Compared to YAPHEU, YAPHIV were older and from families with higher median income and fewer symptoms of parent/caregiver mental health/substance use disorders. Proportions of YAPHIV and YAPHEU, respectively, who achieved each milestone were comparable: 82% versus 78% for high school graduation (p = 0.49), 45% versus 51% for postsecondary education (p = 0.35) and 48% versus 54% for current employment (p = 0.32). Higher cognitive efficiency was positively associated with postsecondary education and current employment. Higher executive function, age-appropriate behavioural/social-emotional functioning and lower cumulative risk were associated with academic milestones. Among YAPHIV, positive associations were: higher current CD4 with postsecondary education and lower nadir CD4 with current employment. PHIV status did not modify any association. CONCLUSIONS YAPHIV and YAPHEU demonstrated resilience, attaining at least one young adult milestone. Cognitive, behavioural and social resources to support resilience in childhood and adolescence may provide the foundation for continued achievement throughout adulthood.

Abstract
BACKGROUND Increasing numbers of children with perinatally acquired HIV (PaHIV) are transitioning into adult care. People living with behaviourally acquired HIV are known to be at more risk of psychosis than uninfected peers. Young adults living with PaHIV face numerous risk factors; biological: lifelong exposure to a neurotrophic virus, antiretroviral medication and immune dysfunction during brain development, and environmental; social deprivation, ethnicity-related discrimination, and migration-related issues. To date, there is little published data on the prevalence of psychotic illness in young people growing up with PaHIV. METHODS We conducted a retrospective case note review of all individuals with PaHIV aged over 18 years registered for follow up at a dedicated clinic in the UK (n = 184). RESULTS In total, 12/184 (6.5%), median age 23 years (interquartile range 21-26), had experienced at least one psychotic episode. The presentation and course of the psychotic episodes experienced by our cohort varied from short-lived symptoms to long term illness and nine (75%) appear to have developed a severe and enduring mental illness requiring long term care. CONCLUSION The prevalence of psychosis in our cohort was clearly above the lifetime prevalence of psychosis in UK individuals aged 16-34 years, which has been reported to be 0.5-1.0%. This highlights the importance of clinical vigilance regarding the mental health of young people growing up with PaHIV and the need to integrate direct access to mental health services within the HIV centres providing medical care.

Abstract
Human immunodeficiency virus (HIV)/Aquired Immune Deficiency Syndrome (AIDS) is a large threat to human health and is challenging to address. This study aims to determine if motor intervention is a possibility for promoting the life expectancy and quality of life of children with HIV. The group consisted of 22 participants: 11 HIV-infected (51.73 months, SD 10.15) and 11 HIV-affected children (44.45 months, SD 10.76). A two-group (intervention and control group) pre-test−post-test research design was followed. The HIV-infected and affected children were randomly matched and grouped into an intervention and control group. The intervention group participated in a 12-week motor intervention of 60 min per session, twice per week. The effect of the program was analyzed with regard to motor skills, as established by the PDMS-2 and two strength capabilities. An ANCOVA adjusted for pre-test differences (p < 0.05) indicated statistically significant improvement (p < 0.05) with large practical significance (d > 0.8) in locomotor, fine motor and overall motor skills. The infected children also showed better improvement compared to the affected children. Motor intervention is recommended in the health care path of children affected and infected with HIV, although modifications for improvement of the program are suggested, based on the results attained.

Abstract
Background There is growing concern about the long-term sequelae [a condition which is the consequence of a previous disease or injury] of perinatally acquired human immunodeficiency virus (HIV). Children living with HIV (CLHIV) present with cardiopulmonary impairments and decreased physical activity which may be due to poor endurance. Objectives Our study aimed to investigate the sub-maximal endurance of CLHIV compared to a non-infected comparison group. Methods In this cross-sectional descriptive study 346 CLHIV, between ages five and eleven years, were assessed using the Six Minute Walk Test (6MWT). Blood pressure, heart rate and oxygen saturation were measured pre-test, immediately post-test and five minutes post-test. Clinical and anthropometric data were recorded. Height and weight were assessed using a stadiometer and a digital scale, respectively. Results 175 CLHIV (52% female) and 171 children without HIV (46% female) participated. All children were Black African. The CLHIV all initiated antiretroviral therapy (ART) at a young age (mean 8.7 months, standard deviation 6.7) and their disease was well controlled (viral load < 1000copies/ml). There were no statistically significant differences in submaximal endurance between the two groups (p = 0.831). Age of starting ART and stunted growth were negatively associated (r = -2.8 (p = 0.019) and r = -46.1 (p = 0.027), respectively) with distance walked in the 6MWT by girls living with HIV. Conclusion CLHIV who initiate ART early with well-controlled disease are able to attain submaximal endurance levels similar to their uninfected peers. Clinical implications Endurance and physical activity should be monitored in CLHIV. Submaximal endurance levels may improve with age and biological maturation.

Abstract
Purpose of Review Perinatally acquired HIV infection (PHIV) can confer neurodevelopmental risk. As children with PHIV increasingly survive through adolescence and into adulthood, understanding its long-term central nervous system (CNS) impacts is critical for maximizing adult outcomes and quality of life. Recent Findings Recently published neurocognitive and neuroimaging findings show impacts on the CNS associated with early HIV disease progression that endure into adolescence and young adulthood. Although developmental trajectories in adolescence largely appear stable, further research on maturational processes is indicated. Summary Although early antiretroviral therapy in infancy appears to be protective, it is not universally available and current youth largely developed without its benefit. The neurocognitive effects of HIV and the multiple other risks to neurodevelopment experienced by youth with PHIV call for further longitudinal research and a multifaceted approach to prevention and intervention.

Abstract
Introduction Older adolescents aged 15–19 years continue to have high rates of loss to follow up (LTFU), and high rates of virologic non‐suppression (VNS) compared to younger adolescents and adults. Adolescent females are at risk of pregnancy, which puts those living with HIV at a dual vulnerability. Our study assessed the factors associated with VNS and LTFU in older adolescents (including pregnant females) who initiated antiretroviral therapy (ART) in South Africa. Methods We included adolescents aged 15–19 years initiating ART between 2004 and 2019, with ≥ one viral load (VL) measurement between 4 and 24.5 months, and ≥ 6 months follow‐up, from six South African cohorts of the International epidemiology Databases to Evaluate AIDS‐Southern Africa (IeDEA‐SA). We defined VNS as VL ≥400 copies/ml and LTFU as not being in care for ≥180 days from ART start and not known as transferred out of the clinic or dead in the first 24 months on ART. We examined factors associated with VNS and LTFU using Fine&Gray competing risk models. Results We included a total of 2733 adolescents, 415 (15.2%) males, median (IQR) age at ART start of 18.6 (17.3, 19.4) years. Among females, 585/2318 (25.2%) were pregnant. Over the 24‐month follow‐up, 424 (15.5%) of all adolescents experienced VNS: range (11.1% pregnant females and 20.5% males). Over half of all adolescents were LTFU before any other event could occur. The hazard of VNS reduced with increasing age and CD4 count above 200 cells/μl at ART initiation among all adolescents having adjusted for all measured patient characteristics [adjusted sub‐distribution hazard ratio (aSHR) 19 vs. 15 years: 0.50 (95% CI: 0.36, 0.68), aSHR: >500 vs. ≤200 cells/μl: 0.22 (95% CI: 0.16, 0.31)]. The effect of CD4 count persisted in pregnant females. Increasing age and CD4 count >200 cells/μl were risk factors for LTFU among all adolescents. Conclusions Older adolescents had a high risk of LTFU shortly after ART start and a low risk of VNS, especially those initiating treatment during pregnancy. Interventions addressing adherence and retention should be incorporated into adolescent‐friendly services to prevent VNS and LTFU and endeavour to trace lost adolescents as soon as they are identified.

Viruses 2021; 13:2543. [PMID: 34960812 PMCID: PMC8706807 DOI: 10.3390/v13122543] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2021] [Revised: 12/13/2021] [Accepted: 12/14/2021] [Indexed: 12/29/2022] Open
Abstract
HIV-1 is known for its complex interaction with the dysregulated immune system and is responsible for the development of neurocognitive deficits and neurodevelopmental delays in pediatric HIV populations. Considering that HIV-1-induced immune dysregulation and its association with neurodevelopmental and neurocognitive impairments in pediatric populations are not well understood, we conducted a scoping review on this topic. The study aimed to systematically review the association of blood and cerebrospinal fluid (CSF) immune markers with neurocognitive deficits and neurodevelopmental delays in pediatric HIV populations. PubMed, Scopus, and Web of Science databases were searched using a search protocol designed specifically for this study. Studies were selected based on a set eligibility criterion. Titles, abstracts, and full texts were assessed by two independent reviewers. Data from the selected studies were extracted and analyzed by two independent reviewers. Seven studies were considered eligible for use in this context, which included four cross-sectional and three longitudinal studies. An average of 130 (±70.61) children living with HIV, 138 (±65.37) children exposed to HIV but uninfected and 90 (±86.66) HIV-negative participants were included across the seven studies. Results indicate that blood and CSF immune markers are associated with neurocognitive development/performance in pediatric HIV populations. Only seven studies met the inclusion criteria, therefore, these limited the number of significant conclusions which could have been made by using such an approach. All considered, the evidence suggests that immune dysregulation, as in the case of adult HIV populations, also has a significant association with neurocognitive performance in pediatric HIV populations.

Abstract
Pediatric HIV infection remains a global health crisis with an estimated 150,000 new mother-to-child (MTCT) infections each year. Antiretroviral therapy (ART) has improved childhood survival, but only an estimated 53% of children worldwide have access to treatment. Adding to the health crisis is the neurological impact of HIV on the developing brain, in particular cognitive and executive function, which persists even when ART is available. Imaging studies suggest structural, connectivity, and functional alterations in perinatally HIV-infected youth. However, the paucity of histological data limits our ability to identify specific cortical regions that may underlie the clinical manifestations. Utilizing the pediatric simian immunodeficiency virus (SIV) infection model in infant macaques, we have previously shown that early-life SIV infection depletes the neuronal population in the hippocampus. Here, we expand on these previous studies to investigate the dorsolateral prefrontal cortex (dlPFC). A total of 11 ART-naïve infant rhesus macaques (Macaca mulatta) from previous studies were retrospectively analyzed. Infant macaques were either intravenously (IV) inoculated with highly virulent SIVmac251 at ~1 week of age and monitored for 6-10 weeks or orally challenged with SIVmac251 from week 9 of age onwards with a monitoring period of 10-23 weeks post-infection (19-34 weeks of age), and SIV-uninfected controls were euthanized at 16-17 weeks of age. Both SIV-infected groups show a significant loss of neurons along with evidence of ongoing neuronal death. Oral- and IV-infected animals showed a similar neuronal loss which was negatively correlated to chronic viremia levels as assessed by an area under the curve (AUC) analysis. The loss of dlPFC neurons may contribute to the rapid neurocognitive decline associated with pediatric HIV infection.

Abstract
Due to the widespread access to, and implementation of, combination antiretroviral therapy, individuals perinatally infected with human immunodeficiency virus type 1 (HIV-1) are living into adolescence and adulthood. Perinatally infected adolescents living with HIV-1 (pALHIV) are plagued by progressive, chronic neurocognitive impairments; the pathophysiological mechanisms underlying these deficits, however, remain understudied. A longitudinal experimental design from postnatal day (PD) 30 to PD 180 was utilized to establish the development of pyramidal neurons, and associated dendritic spines, from layers II-III of the medial prefrontal cortex (mPFC) in HIV-1 transgenic (Tg) and control animals. Three putative neuroinflammatory markers (i.e., IL-1β, IL-6, and TNF-α) were evaluated early in development (i.e., PD 30) as a potential mechanism underlying synaptic dysfunction in the mPFC. Constitutive expression of HIV-1 viral proteins induced prominent neurodevelopmental alterations and progressive synaptodendritic dysfunction, independent of biological sex, in pyramidal neurons from layers II-III of the mPFC. From a neurodevelopmental perspective, HIV-1 Tg rats exhibited prominent deficits in dendritic and synaptic pruning. With regards to progressive synaptodendritic dysfunction, HIV-1 Tg animals exhibited an age-related population shift towards dendritic spines with decreased volume, increased backbone length, and decreased head diameter; parameters associated with a more immature dendritic spine phenotype. There was no compelling evidence for neuroinflammation in the mPFC during early development. Collectively, progressive neuronal and dendritic spine dysmorphology herald synaptodendritic dysfunction as a key neural mechanism underlying chronic neurocognitive impairments in pALHIV.

Abstract
OBJECTIVE This scoping review aims to identify and describe the physical sequelae experienced by adolescents with perinatally acquired HIV. INTRODUCTION Perinatally acquired HIV is a prevalent condition affecting adolescents. It results in neurocognitive dysfunction and mental health challenges. Data show that some of the physical challenges facing this population include stunted growth and delayed puberty; however, other physical challenges remain largely unknown. INCLUSION CRITERIA This review will consider studies that include adolescents aged 10 to 19 years, with perinatally (vertically) acquired HIV. Adolescents from any geographic area, of any ethnicity or socioeconomic background will be considered. The concepts included will be all physical sequelae of perinatally acquired HIV. Studies of any research design, including quantitative, qualitative, and mixed methods, as well as systematic reviews, will be considered. METHODS This review will utilize a three-step search strategy. There will be an initial search of MEDLINE (PubMed), followed by a full search of MEDLINE (PubMed), PEDro, CINAHL (EBSCO), Scopus (Elsevier), ScienceDirect (Elsevier), and Google Scholar. Gray literature will be searched using CDC Stacks and OpenGrey. Lastly, the reference lists of all articles will be checked for additional studies. Titles and abstracts will be screened by two independent reviewers against the inclusion criteria, and a third reviewer will resolve any discrepancies. Results will be charted on a data extraction tool and presented with a table, diagrammatic representation, and a descriptive narrative.

Abstract
Advances in antiretroviral treatment improved the life expectancy of perinatally HIV-infected children. However, growing up with HIV provides challenges in daily functioning. This cross-sectional cohort study investigated the neuropsychological and psychosocial functioning of a group of perinatally HIV-infected children in the Netherlands and compared their outcomes with Dutch normative data and outcomes of a control group of uninfected siblings. The children’s functioning was assessed with internationally well-known and standardized questionnaires, using a multi-informant approach, including the perspectives of caregivers, teachers, and school-aged children. In addition, we explored the associations of socio-demographic and medical characteristics of the HIV-infected children with their neuropsychological and psychosocial functioning. Caregivers reported compromised functioning when compared to Dutch normative data for HIV-infected children in the areas of attention, sensory processing, social-emotional functioning, and health-related quality of life. Teachers reported in addition compromised executive functioning for HIV-infected children. A comparison with siblings revealed differences in executive functioning, problems with peers, and general health. The concurrent resemblance between HIV-infected children and siblings regarding problems in other domains implies that social and contextual factors may be of influence. A family-focused approach with special attention to the child’s socio-environmental context and additional attention for siblings is recommended.

Components of metabolic syndrome associated with lower neurocognitive performance in youth with perinatally acquired HIV and youth who are HIV-exposed uninfected. J Neurovirol 2021; 27:702-715.

Abstract
We investigated the association of metabolic syndrome (MetS) and its components [abdominal obesity, elevated triglycerides (TG), low HDL cholesterol, elevated blood pressure (BP), and impaired fasting glycemia (IFG)] with neurocognitive impairment in youth with perinatally acquired HIV (YPHIV) or who are perinatally HIV-exposed uninfected (YPHEU). This was an observational study with a comparison group of 350 YPHIV and 68 YPHEU ages 10-19 years. Youth with MetS components measured between 1 year before and 3 months after a baseline neurocognitive assessment (Wechsler Intelligence Scale) were selected from the Pediatric HIV/AIDS Cohort Study (PHACS). A sub-group completed another assessment 3 years later. We assessed the association of each baseline MetS component with five standardized neurocognitive indices at baseline and changes in indices over time. At baseline, 15% of YPHIV and 18% of YPHEU met criteria for ≥ 2 MetS components. Among YPHIV, there was no association between MetS components and neurocognitive indices at baseline; however, over time, elevated baseline BP was associated with a greater decrease in mean Perceptual Reasoning scores (-4.3;95%CI: -8.8,0.3) and ≥ 2 MetS components with a greater decrease in mean Processing Speed scores (-5.1;95%CI: -9.4, -0.8). Among YPHEU, elevated TG was associated with lower mean Verbal Comprehension, Perceptual Reasoning, and Full-scale IQ scores at baseline, and IFG with lower mean Verbal Comprehension scores. Components of MetS in YPHIV (elevated BP) and YPHEU (elevated TG and IFG) were associated with lower neurocognitive performance index scores. Studies to elucidate how modifying metabolic risk factors early in life may improve neurocognitive outcomes in this population are warranted.

Abstract
Introduction Since the introduction of combination antiretroviral therapy, human immunodeficiency virus (HIV) infection is a manageable chronic disease. However, school-age children (4–18 years) living with HIV could still experience problems with functioning at school, due to the impact of the virus itself, medication, comorbidities and social stigma. School functioning covers academic achievement, school attendance, and social relationships and is of utmost importance to optimize normal participation. Methods To gain insight in school functioning problems of perinatally HIV-infected children, we performed a systematic review of the literature in multiple databases from January 1997 up to February 2019. Studies were included if they described outcomes of school functioning of school-age children perinatally infected with HIV, in high-income countries. Meta-analyses were performed for sufficiently comparable studies. Results and discussion Results from 32 studies show that HIV-infected children experience more problems in various areas of school functioning in comparison with national norms, matched healthy controls, siblings and HIV-exposed uninfected (HEU) children. The most pronounced differences concerned the usage of special educational services, general learning problems, and mathematics and reading performance scores. Comparisons with both national norms and siblings/HEU children show that the differences between HIV-infected children and siblings/HEU children were less pronounced. Moreover, siblings/HEU children also reported significantly worse outcomes compared to national norms. This suggests that problems in school functioning cannot be solely attributed to the HIV-infection, but that multiple socio-economic and cultural factors may play a role herein. Conclusion Perinatally HIV-infected children seem vulnerable to problems in various areas of school functioning. Therefore, monitoring of school functioning should be an important aspect in the care for these children. A family-focused approach with special attention to a child’s socio-environmental context and additional attention for siblings and HEU children, is therefore recommended.

Abstract
BACKGROUND Children living with human immunodeficiency virus (HIV) are at neuropsychological risk for cognitive and motor dysfunction. However, few prospective, multi-site studies have evaluated neuropsychological outcomes longitudinally among perinatally infected African children who received early antiretroviral treatment (ART). METHODS We enrolled 611 children aged 5 to 11 years at 6 sites (South Africa [3], Zimbabwe, Malawi, Uganda). Of these, there were 246 children living with HIV (HIV+) who were initiated on ART before 3 years of age in a prior clinical trial comparing nevirapine to lopinavir/ritonavir (International Maternal Pediatric Adolescent Acquired Immunodeficiency Syndrome Clinical Trials [IMPAACT] P1060); 183 age-matched, exposed but uninfected (HEU) children; and 182 unexposed and uninfected (HUU) children. They were compared across 3 assessment time points (Weeks 0, 48, and 96) on cognitive ability (Kaufman Assessment Battery for Children, second edition [KABC-II]), attention/impulsivity (Tests of Variables of Attention [TOVA]), motor proficiency (Bruininks-Oseretsky Test, second edition [BOT-2]), and on the Behavior Rating Inventory of Executive Function (BRIEF). The cohorts were compared using linear mixed models, adjusting for site, child's age and sex, and selected personal/family control variables. RESULTS The HIV+ cohort performed significantly worse than the HEU and HUU cohorts for all KABC-II, TOVA, and BOT-2 performance outcomes across all 3 time points (P values < .001). The HUU and HEU cohorts were comparable. For the KABC-II planning/reasoning subtests, the HIV+ children showed less improvement over time than the HUU and HEU groups. The groups did not differ significantly on the BRIEF. CONCLUSIONS Despite initiation of ART in early childhood and good viral suppression at the time of enrollment, the HIV+ group had poorer neuropsychological performance over time, with the gap progressively worsening in planning/reasoning. This can be debilitating for self-management in adolescence.

Neurocognitive function among HIV-infected children on protease inhibitor -based versus non-protease inhibitor based antiretroviral therapy in Uganda: a pilot study. BMC Pediatr 2021; 21:198. [PMID: 33902506 PMCID: PMC8073947 DOI: 10.1186/s12887-021-02676-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/01/2021] [Accepted: 04/16/2021] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND HIV infection is associated with significant neurocognitive deficits making maximization of cognitive function among children receiving antiretroviral therapy (ART) a public health imperative. Non-protease inhibitors (non-PIs) achieve higher drug levels in the cerebral spinal fluid (CSF) compared to PIs, potentially leading to better neurocognitive function by reducing CSF viral load and inflammation. ART that maximises children's neurodevelopment and school achievement could result in improved quality of life and productivity as adults, but little research to date has examined whether non-PI ART is associated with better neurocognitive outcomes. We compared the neurocognitive function between children living with HIV receiving PI-based and non PI-based ART. METHODS We recruited a consecutive sample of clinically stable Ugandan children living with HIV aged 5-12 years who received PI-based or non PI-based ART for ≥ 1 year (viral load < 1000 copies). Neurocognitive function was assessed using the Kaufman Assessment Battery for Children, the Test of Variables of Attention, and Bruininks-Oseretsky Test of Motor Proficiency. Age-adjusted neurocognitive z-scores for the two groups were compared using linear regression models in STATA version 13. The Hommel's method was used to adjust for multiple testing. RESULTS We enrolled 76 children living with HIV; 34 on PI ART and 42 on non-PI ART. Mean (±SD) age was greater in the non-PI vs. PI group (9.5 ± 1.9 vs. 8.5 ± 2.0) years (p = 0.03). Children in the non-PI group had lower socioeconomic scores (5.7 ± 3.3 vs. 7.4 ± 2.8, p = 0.02). There was no difference in neurocognitive function between the groups (adjusted p > 0.05) for KABC and TOVA. Children in the PI group had better total BOT scores than their counterparts (46.07 ± 1.40) vs. 40.51 (1.24), p = 0.03). CONCLUSIONS We detected no difference in neurocognitive function among children on PI and non PI-based ART therapy based on KABC and TOVA tests. Children on PI based ART had better motor function than their counterparts. We recommend a prospective study with a larger sample size.

Abstract
Strategies are needed to optimize HIV health care transition (HCT). We describe HCT outcomes within the University of Maryland STEP Program, which is built upon integration of an adult HIV provider and navigator into the pediatric clinic, and coordinated collaboration between pediatric and adult HIV multi-disciplinary care teams. These outcomes were compared to a historical institutional HCT cohort (N = 50) which attempted transition in an earlier time period (2004-2012). Fifty-eight patients were enrolled during the study period, and 34 attempted HCT. In total, 84 patients underwent attempted HCT. In the STEP cohort, linkage to adult care was 94% and 12 month retention in adult care (95%) was statistically higher compared to the historical cohort. Rates of viral suppression did not differ pre- and post-HCT among STEP Program patients. These results support the concept of an integrated pediatric and adult HIV HCT model though the ability to achieve sustainable HCT success will require further study.

Abstract
Construct validity of novel tablet-based neurocognitive tests (in the NeuroScreen app) measuring processing speed, working memory, and executive functioning in adolescents and young adults (AYA) living with perinatally-acquired HIV (PHIV) and perinatal HIV-exposure without infection (PHEU) was examined. Sixty-two AYA (33 PHIV, 29 PHEU) were recruited from an ongoing longitudinal study (CASAH) in New York City. Medium to large and statistically significant correlations were found between NeuroScreen and gold standard, paper-and-pencil tests of processing speed, working memory, and executive functioning. Results provide partial support for NeuroScreen as an alternative to cumbersome paper-and-pencil tests for assessing neurocognition among HIV-affected AYA.

Abstract
In perinatally HIV-infected (PHIV) children, neurodevelopment occurs in the presence of HIV-infection, and even with combination antiretroviral therapy (cART) the brain can be a reservoir for latent HIV. Consequently, patients often demonstrate long-term cognitive deficits and developmental delay, which may be reflected in altered functional brain activity. Our objective was to examine brain function in PHIV on cART by quantifying the amplitude of low frequency fluctuations (ALFF) and regional homogeneity (ReHo). Further, we studied ALFF and ReHo changes with neuropsychological performance and measures of immune health including CD4 count and viral loads in the HIV-infected youths. We found higher ALFF and ReHo in cerebral white matter in the medial orbital lobe for PHIV (N = 11, age mean ± sd = 22.5 ± 2.9 years) compared to controls (N = 16, age = 22.5 ± 3.0 years), with age and gender as co-variates. Bilateral cerebral white matter showed increased spontaneous regional activity in PHIV compared to healthy controls. No brain regions showed lower ALFF or ReHo in PHIV compared to controls. Higher log10 viral load was associated with higher ALFF and ReHo in PHIV in bilateral cerebral white matter and right cerebral white matter respectively after masking the outcomes intrinsic to the brain regions that showed significantly higher ALFF and ReHo in the PHIV compared to the control. Reductions in social cognition and abstract thinking in PHIV were correlated with higher ALFF at the left cerebral white matter in the left medial orbital gyrus and higher ReHo at the right cerebral white matter in the PHIV patients. Although neuroinflammation and associated neuro repair were not directly measured, the findings support their potential role in PHIV impacting neurodevelopment and cognition.

Abstract
BACKGROUND With combination antiretroviral therapy (cART), infants with perinatally acquired HIV (pHIV) are living into adolescence and adulthood. Worldwide, many have not received cART in the first years of life, and challenges of adolescence complicate transition to adulthood. Neurobehavioral outcomes in pHIV young adults (pHIVAd) are infrequently reported. OBJECTIVES To examine neurobehavioral characteristics of pHIVAd ages 21-30 years, and to compare them with age-matched young adults infected in the second or third decade of life (HIVagematch), and older adults with similar duration HIV disease (HIVOA). METHODS A comprehensive neuropsychological test battery and questionnaires to determine cognitive function and mood, and reviews of neuromedical and behavioral records were undertaken in three groups of 13 individuals each. Descriptive analysis and bivariate techniques were used for comparisons. RESULTS Rates of cognitive impairment were highest in pHIVAd (85%) compared with HIVagematch (38%) and HIVOA (62%). pHIVAd had the worst scores in global cognition, speed of information processing, working memory, and verbal fluency (0.5--1.0 SD below other groups). There was a trend for higher rates of psychiatric dysfunction (predominantly mood disorders) in pHIVAd (85%) compared with HIV-agematch (46%) and HIVOA (54%). Only four pHIVAd reported employment or enrollment in school. Four had autoimmune disorders. CONCLUSION These pHIVAd displayed high rates of cognitive, psychiatric, and autoimmune dysfunction, greater than age-matched or HIV duration-matched comparators. Although this small study is largely descriptive in nature, it suggests that a lack of cART in early life may result in long-term neurobehavioral and immune abnormalities manifesting into adulthood.

Abstract
Many children and adolescents around the world suffer from neurocognitive deficits due to chronic disorders, such as Human Immunodeficiency Virus (HIV) and malaria. Resource-limited settings exacerbate the risk of negative cognitive outcomes due to high prevalence of associated disorders, poverty, and limited access to interventions. Current literature does not provide consensus regarding the efficacy of interventions to support children with cognitive impairments in low-resource settings. This research aimed to identify and evaluate interventions for youth with neurocognitive deficits in resource-limited settings. A systematic review of peer-reviewed literature was conducted within five databases (PubMed, Web of Science, CINAHL, PsycInfo, and WHO Index Medicus). Cognitive impairment was broadly defined to be inclusive of aspects of intellectual and cognitive functioning (e.g., working memory, attention, executive function). The income status of the country or countries in which each study was located was determined according to World Bank Income Status. Studies conducted in countries classified as low- or middle-income were included. Since low-resource areas exist within high-income countries, the resource availability within study settings in high-income countries was systematically evaluated for inclusion. The search yielded 19 articles that met all inclusion criteria. Interventions included strategies involving caregiver training, computerized and non-computerized cognitive training, physical activity, and nutritional supplementation. Interventions were administered in medical facilities, educational facilities, or the home. The majority of the interventions targeted the domains of memory and attention. Overall, the efficacy of interventions was inconsistent. Further, results indicated that the relationship between cognitive improvement and intervention types was not consistent across cognitive domains. However, when evaluating studies on an individual basis, some strategies demonstrated clinically- and statistically-significant improvement in cognitive function among specific groups of children. The low article yield highlights that few researchers have evaluated pediatric cognitive support interventions in low-resource contexts. This review suggests support strategies that should be considered for future studies as neurocognitive screening capacity improves in resource-limited settings.

Differences in location of cerebral white matter hyperintensities in children and adults living with a treated HIV infection: A retrospective cohort comparison. PLoS One 2020; 15:e0241438.

Abstract
Cerebral white matter hyperintensities (WMH) persist in children and adults living with HIV, despite effective combination antiretroviral therapy (cART). As age and principal routes of transmission differ between children (perinatally) and adults (behaviorally), comparing the characteristics and determinants of WMH between these populations may increase our understanding of the pathophysiology of WMH. From separate cohorts of 31 children (NOVICE) and 74 adults (AGEhIV), we cross-sectionally assessed total WMH volume and number of WMH per location (periventricular vs. deep) using fluid-attenuated inversion recovery (FLAIR) MRI images. WMH were either periventricular when within 10mm of the lateral ventricles, or deep otherwise. We assessed patient- or HIV-related determinants of total WMH volume (adjusted for intracranial volume) and location of WMH using logistic regression, while stratifying on children and adults. At enrollment, median age of participants was 13.8 years (IQR 11.4-15.9) for children and 53.4 years (IQR 48.3-60.8) for adults and 27/31 children (87%) and 74/74 adults (100%) had an HIV RNA viral load <200 copies/mL. WMH were present in 16/27 (52%) children and 74/74 adults (100%). The prevalence of deep WMH was not different between groups, (16/16 [100%] in children vs. 71/74 [96%] in adults, p = 0,999), yet periventricular WMH were more prevalent in adults (74/74 [100%]) compared to children (9/16; 56%) (p<0.001). Median WMH volume was higher in adults compared to children (1182 mm3 [425-2617] vs. 109 mm3 [61.7-625], p<0.001). In children, boys were more likely to have deep WMH compared to girls. In adults, older age was associated with higher total WMH volume, and age, hypertension and lower CD4+ T-lymphocyte nadir with a higher number of periventricular WMH. Our findings suggest that the location of WMH differs between children and adults living with HIV, hinting at a different underlying pathogenesis.

Abstract
Human immunodeficiency virus (HIV) is a neurotropic virus that has a detrimental impact on the developing central nervous system (CNS) of children growing up with perinatal HIV (PHIV) due to a combination of pathophysiological processes related to direct viral cytopathic effects and immune activation. This leads to a spectrum of neurocognitive impairment ranging from severe encephalopathy to subtle domain-specific cognitive impairments, as well as psychological disorders that are compounded by HIV-related stigma and sociodemographic factors that disproportionately affect PHIV children. Early commencement and consistent use of combination antiretroviral therapy (cART) has resulted in a dramatic improvement in neuropsychological outcomes for PHIV children; however, they remain vulnerable to cognitive impairment and psychological disorders, as evidenced by imaging findings, randomised clinical trials and observational studies. An optimal neuroprotective cART regimen remains elusive in children, but systemic viral suppression, regular neurocognitive and psychological screening and ready access to neuropsychological management strategies are key components for optimising neuropsychological outcomes. However, a lack of standardised and validated screening tools, particularly in resource-limited settings, hinders a precise understanding of the nature, prevalence and associations between neuropsychological symptomatology and HIV health. This article reviews the natural history, cellular pathophysiology and structural and functional imaging findings for children growing up with HIV, as well as summarising management strategies related to antiretroviral therapy, screening tools and specific interventions for neurocognitive impairments and psychological disorders.

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
OBJECTIVE To analyze the results of the audiological evaluation of children with HIV and AIDS. DATA COLLECTION Systematic review carried out in May 2019 in the Web of Science, PubMed, SciELO, and Scopus databases. Case reports and original articles were included, with no limitationsregarding country or year of publication. DATA SYNTHESIS 278 articles were identified; 26 were included, in which HIV/AIDS was shown to be a risk factor for hearing loss (OR=5.364; p=0.00). The studies used different audiological exams, with varying methodologies. There was no difference regarding the type of hearing loss (p=0.119). CONCLUSION Longitudinal studies using the same type of examination at all stages are suggested, to allow better monitoring of the effects of HIV on the child's hearing,and studies that provide more methodological details. The knowledge of the influence of HIV on the child's auditory system may lead to the promotion of measures that minimize the prevalence of hearing loss, allow an early diagnosis and timely rehabilitation, so as not to compromise child development.

Abstract
BACKGROUND Adolescents living with HIV (ALHIV) in Malawi experience multiple challenges associated with their illness and various social, environmental, economic and cultural factors. In exploring their various medical concerns and social vulnerabilities, we consider the role of multiple services in creating a pathway for resilience. METHODS Multiple methods and case studies allowed for triangulation of evidence and provided a holistic understanding of resilience among adolescents with complex needs. The research methods included: (1) a survey to identify examples of young people with complex needs, (2) qualitative interviews and field notes to further explore these needs, (3) patient files and health passports to identify clinical challenges, and (4) ecomapping exercises to personalize cases and identify resilience-enabling resources and supports. We present four case studies to highlight the complex experiences and access to services of ALHIV, and to illustrate their growing power and decision-making capacity over time. RESULTS Adversity experienced by ALHIV varied by gender, family situation, years of schooling, and use of teen-clubs for support. The two female adolescents emphasised their need to be accepted and how this impacted sexuality and reproduction. The two males illustrated how ideas of masculinity influenced their sexual practice and involvement with health services and the correctional justice system. Multiple risks (alcohol use, sexual activities) and complex needs (belonging, having a purpose in life/productive activities, autonomy, desire for offspring) influence pathways to resilience. ALHIV were able to strengthen their own wellbeing by resisting negative behaviours and peer pressure and caregiver interactions through 'strategic silence'. CONCLUSION ALHIV experienced self-transformation as a result of taking ART, with fewer severe episodes of illness and distressing skin conditions. Continuous engagement at the teen-club clinic transformed both productive activities and social relationships among ALHIV as they set life goals, gained a sense of empowerment, requested SRH services, and formed intimate relationships. These transformative opportunities allowed them to learn ways of minimizing risk of reinfection and violence, and of navigating health worker-caregiver-adolescent interactions.

Abstract
Delayed neurodevelopment is a common outcome in perinatally HIV-infected children. Our aim was to assess the intellectual profile of our cohort, considering both the infection and socio-environmental related variables. A cross-sectional cohort study was undertaken at seven major hospitals in Spain belonging to the CoRISpeS cohort (n = 97). Patients were followed up according to a standard protocol. Intellectual measures, psychosocial profile and HIV infection-related data have been analysed. The average patient age was 15 years. The median CD4 cell percentage was 35% (1,59). Viral load was undetectable in 80% of the patients and 27% were on AIDS category; 38% of whom had encephalopathy. The average composite score of both crystallized intelligence (CI) and intelligence quotient (IQ) for the cohort was lower than that of the general population (p < 0.001). Results revealed a significant difference of 38% between crystallized and fluid intelligence. There was a clear association between IQ and age of diagnosis (p = 0.022); CI and CDC classification (p = 0.035), CD4 count (p = 0.011) and CD4 nadir (p = 0.001). Higher parental education was associated with better performance across all intelligence scales (p < 0.002). A regression model showed that CI was influenced by the academic level of caregivers (p = 0.002), age at start of cART (p = 0.050) and primary language (p = 0.058). Findings revealed significant differences in verbal and non-verbal intellectual scales resulting in a misleading IQ Composite score. Crystallized intelligence demonstrated the highest level of impairment despite adequate treatment and good immunovirological status, while fluid intelligence results were average. Caregiver level of education was the strongest factor across all intelligence measures.

The effect of HIV infection and exposure on cognitive development in the first two years of life in Malawi. Eur J Paediatr Neurol 2020; 25:157-164. [PMID: 31791872 PMCID: PMC7136137 DOI: 10.1016/j.ejpn.2019.11.004] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2018] [Revised: 05/30/2019] [Accepted: 11/17/2019] [Indexed: 11/21/2022]
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
OBJECTIVE Little is known about pregnancy outcomes among women who have acquired human immunodeficiency virus (HIV) through perinatal infection and survived into adulthood. The objectives of this study were to describe pregnancy outcomes among women with perinatal HIV infection (PHIV) in Canada and to identify potential challenges in the prevention of perinatal HIV transmission in this population. METHODS A retrospective review of all pregnancies among women with PHIV who were previously followed as children at two tertiary care centres in Montréal, Québec, was conducted. Data were extracted from pediatric and obstetrical records. RESULTS There were 21 pregnancies among 11 women, and 18 of these pregnancies were unintentional. Mean age at first pregnancy was 19.5 years (range 15-29 years). At the first prenatal visit, 79% had a detectable viral load, 36% were immunosuppressed (CD4 T cell count <200 mm3), and only 36% were receiving antiretroviral therapy (ART). At the time of delivery, although all were prescribed ART, 50% of these women still had a detectable viral load, and 36% remained immunosuppressed. All of the women harboured mutations conferring drug resistance to zidovudine and lamivudine, and the majority (73%) were also resistant to nevirapine. None of the infants were HIV infected, although all received prophylaxis with agents to which their mother's virus was resistant. CONCLUSION Unplanned pregnancies, difficulties with adherence to ART, and drug resistance were identified challenges in the management of pregnancies among women with PHIV. This study highlights a gap in the reproductive counselling of adolescents with PHIV and the need for close follow-up and adherence support during pregnancy in this population.

Abstract
BACKGROUND Monocyte activation may contribute to neuronal injury in aviremic HIV-infected adults; data are lacking in children. We examined the relation between monocyte activation markers and early and long-term neurodevelopmental outcomes in early-treated HIV-infected children. SETTING Prospective study of infant and child neurodevelopmental outcomes nested within a randomized clinical trial (NCT00428116) and extended cohort study in Kenya. METHODS HIV-infected infants (N = 67) initiated antiretroviral therapy (ART) at age <5 months. Plasma soluble (s) CD163 (sCD163), sCD14, and neopterin were measured before ART (entry) and 6 months later. Milestone attainment was ascertained monthly during 24 months, and neuropsychological tests were performed at 5.8-8.2 years after initiation of ART (N = 27). The relationship between neurodevelopment and sCD163, sCD14, and neopterin at entry and 6 months after ART was assessed using Cox proportional hazards models and linear regression. RESULTS Infants with high entry sCD163 had unexpected earlier attainment of supported sitting (5 vs 6 months; P = 0.006) and supported walking (10 vs 12 months; P = 0.02) with trends in adjusted analysis. Infants with high 6-month post-ART sCD163 attained speech later (17 vs 15 months; P = 0.006; adjusted hazard ratio, 0.47; P = 0.02), threw toys later (18 vs 17 months; P = 0.01; adjusted hazard ratio, 0.53; P = 0.04), and at median 6.8 years after ART, had worse neuropsychological test scores (adj. mean Z-score differences, cognition, -0.42; P = 0.07; short-term memory, -0.52; P = 0.08; nonverbal test performance, -0.39, P = 0.05). CONCLUSIONS Before ART, monocyte activation may reflect transient neuroprotective mechanisms in infants. After ART and viral suppression, monocyte activation may predict worse short- and long-term neurodevelopment outcomes.

Abstract
Background Children infected with human immunodeficiency virus (HIV) are at high risk of acquiring intestinal parasitic infections. This study aimed to determine the magnitude of Cryptosporidium and other intestinal parasitic infections and concomitant threats among HIV-infected children. Methods A hospital-based cross-sectional study was carried out at three antiretroviral therapy clinics in southern Ethiopia from February 2016 to June 2017 in 384 HIV positive children. Socio-demographic and clinical data were collected using structured questionnaires. Direct stool microscopic examination and modified Zeihl–Neelsen staining technique to identify parasites. Chi-square test was conducted to determine the real predictors of the infection. Significant association was considered when p-value <0.05 at 95% CI. Results The overall magnitude of intestinal parasitic infections among the study population was 16.9% (95% CI: 13.0–20.8%). The most predominant parasitic infections were Cryptosporidium spp. (9.6%) and the least was Taenia spp. (0.78%). Diarrheal status (χ2=7.653, df=2, p=0.022) was detected to be the only significant associated variable. Conclusion Cryptosporidium infection was found to be the most common intestinal parasitosis among HIV-infected children. Routine screening service for Cryptosporidium and other intestinal parasites is important in the clinical management of HIV-infected children.

Abstract
Although behavioral problems have been observed in children and adolescents with perinatally-acquired HIV infection (PHIV), behavioral information regarding younger PHIV children are scarce. This study aims to identify behavioral problems in PHIV and HIV-exposed uninfected (HEU) children and to evaluate factors associated with such problems. A prospective study of PHIV and HEU young children was conducted. Behavioral problems were assessed with the Child Behavior Checklist (CBCL) at baseline and 12 months later among children aged 18-60 months old. The Patient Health Questionnaire-9 and the Parenting Styles & Dimensions Questionnaire identified primary caregivers' symptoms of depression and parenting styles, respectively, at both visits. Chi-squared analyses were used to compare the prevalence of behavioral problems between groups. Factors associated with behavioral problems were analyzed by logistic regression. From 2016 to 2017, 121 children (41 PHIV and 80 HEU) were assessed with no significant differences in prevalence of Total, Internalizing, Externalizing, and Syndrome scales problems between PHIV and HEU at both visits (p > 0.5). Primary caregivers' depression and lower education in addition to authoritarian and permissive parenting styles were significantly related to child behavioral problems. Family-centered care for families affected by HIV, including positive parenting promotion, mental health care, and education are warranted.

Abstract
This study investigated working memory (WM) training for adolescents with perinatal HIV infection, since WM is negatively impacted by the virus, and adolescence is a time of considerable brain reorganization, during which WM functioning reaches maturation. We posed three main questions: 1) whether WM could be trained in adolescents living with HIV, and if so, whether these effects were maintained over a six-month period during which no further training was received; 2) whether there were differential effects of training on the components of WM (verbal and visuospatial storage, verbal and visuospatial processing); 3) whether the WM training transferred to cognate tasks, and if so, whether these transfer effects were maintained over six months. Sixty-three HIV+ adolescents (10-16 years) from two children's homes were assigned to the training (n = 31) or control (n = 32) group. The training group received 32 hours of supervised training in an adaptive, computerized WM intervention, while the control group received a supervised, placebo computerized program for the same hours. Comprehensive WM and neuropsychological batteries were administered to both groups at pretest, immediately following the intervention, and six months later. Significant improvements were found in verbal WM for the training group, which were maintained six months later. Transfer effects were evident in attention, executive function, memory, language and fluid intelligence. There were no significant posttest improvements in visuospatial storage, and minimal changes in verbal storage and visuospatial WM. These findings represent an important step in exploring ways to improve cognitive functioning in an at-risk population.

Abstract
Introduction Auditory processing disorders can negatively affect academic performance in children. They can result from a number of aetiologies, including the human immunodeficiency virus (HIV). Although studies in paediatrics are limited, research suggests that HIV-infected children display poorer auditory processing skills than uninfected children. Methods The aims of this study were to scan the peer-reviewed literature on auditory processing skills in HIV-infected children, to describe how auditory processing was tested, how auditory processing skills were reported, and to identify gaps in current evidence. This systematic scoping review was conducted using a modified version of Arksey and O’Malley’s framework. Key words comprised ‘HIV’, ‘auditory processing’, ‘hearing’ and ‘child’. Electronic databases were searched for relevant articles published from 1 January 2000 to 30 April 2018, and reference lists of included studies were pearled. Two researchers reviewed the articles and extracted data on sample descriptors, auditory processing testing procedures, and auditory processing skills. A third author collated the results and resolved discrepancies. The American Speech-Language-Hearing Association description of auditory processing skills framed the analysis. Results Five articles were included in this review (three from Brazil, one each from Mexico and Tanzania). Samples, and methods of testing were heterogeneous. Three studies reported on localization abilities, while gap detection thresholds, performance on dichotic tasks and speech discrimination scores were reported in one article each. No one study tested all areas of auditory processing skills and there was limited information about the auditory processing skills required for learning. Conclusion This review highlighted the current sparse evidence-base for auditory processing in HIV-infected children. It identified the need to standardise testing procedures, measures of auditory processing skills, and sample selection.

Abstract
INTRODUCTION Adolescents with perinatally acquired HIV (PHIV) are at risk of chronic disease due to long-standing immune suppression, HIV disease and antiretroviral therapy (ART) exposure. However, there are few data on multisystem disease in this population. We investigated the overlapping burden of neurocognitive, cardiovascular, respiratory and/or renal impairment among PHIV positive (PHIV+) adolescents. METHODS In this cross-sectional analysis, participants aged 9 to 14 years on ART for >6 months were recruited from seven sites across Cape Town from July 2013 through March 2015, together with age-matched HIV-negative (HIV-) adolescents. Impairment at enrolment was assessed across neurocognitive functioning (using the youth-International HIV Dementia Scale); cardiac function (echocardiogram abnormality); respiratory function (abnormal spirometry) and renal function (abnormal glomerular filtration rate). RESULTS AND DISCUSSION Overall, 384 PHIV+ and 95 HIV- adolescents were included (mean age, 11.9 years; 49% female). Median age of ART initiation was 4.2 years (IQR: 1.7 to 7.6) and median CD4 count was 709 (IQR: 556 to 944) with 302 (79%) of PHIV+ adolescents virologically suppressed. Abacavir and Zidovudine were the most commonly used nucleoside reverse transcriptase inhibitors (NRTIs) with 60% of adolescents on non-nucleoside reverse transcriptase inhibitors (NNRTI) and 38% on a protease inhibitor (PI). Among PHIV+ adolescents, 167 (43.5%) had single system impairment only, 110 (28.6%) had two systems involved, and 39 (10.2%) had three or four systems involved. PHIV+ participants had more 2-system and 3-system impairment than HIV-, 110 (28.6%) versus 17 (17.9%), p = 0.03 and 39 (10.2%) versus 3 (4.3%), p = 0.03. PHIV+ participants who had failed a year of school (73.8% vs. 46.4%, p = 0.00) and with a viral load >1000 copies/mL at enrolment (16.8% vs. 8.1%, p = 0.03) were more likely to have dual or multisystem impairment. Of those with cardiac impairment, 86.7% had an additional system impaired. Similarly, in those with neurocognitive impairment, almost 60% had additional systems impaired and of those with respiratory impairment, 74% had additional systems impaired. CONCLUSIONS Despite relatively early ART initiation, there is a substantial burden of multisystem chronic impairment among PHIV+ adolescents. This phenomenon needs to be further explored as this population ages and begins to engage in adult lifestyle factors that may compound these impairments.
