Brain Behav Immun 2024; 116:101-113. [PMID: 38043871 PMCID: PMC10842701 DOI: 10.1016/j.bbi.2023.11.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Revised: 11/09/2023] [Accepted: 11/23/2023] [Indexed: 12/05/2023] Open
Abstract
Perinatally acquired HIV infection (PHIV) currently affects approximately 1.7 million children worldwide. Youth with PHIV (YPHIV) are at increased risk for emotional and behavioral symptoms, yet few studies have examined relationships between these symptoms and brain structure. Previous neuroimaging studies in YPHIV report alterations within the salience network (SN), cognitive control network (CCN), and default mode network (DMN). These areas have been associated with social and emotional processing, emotion regulation, and executive function. We examined structural brain network integrity from MRI using morphometric similarity networks and graph theoretical measures of segregation (transitivity), resilience (assortativity), and integration (global efficiency). We examined brain network integrity of 40 YPHIV compared to 214 youths without HIV exposure or infection. Amongst YPHIV, we related structural brain network metrics to the Emotional Symptoms Index of the Behavioral Assessment System for Children, 2nd edition. We also examined the relationship of inflammatory biomarkers in YPHIV to brain network integrity. YPHIV had significantly lower global efficiency in the SN, DMN, and the whole brain network compared to controls. YPHIV also demonstrated lower assortativity or resilience (i.e., network robustness) compared to controls in the DMN and whole brain network. Further, higher emotional symptom score was associated with higher global efficiency in the SN and lower global efficiency in the DMN, signaling more emotional challenges. A significant association was also found between several inflammatory and cardiac markers with structural network integrity. These findings suggest an impact of HIV on developing brain networks, and potential dysfunction of the SN and DMN in relation to network efficiency.

Abstract
HIV infection is known to have significant effects on central nervous system. This study conducted a meta-analysis of whole voxel-based morphometry (VBM) in HIV patients (N = 435) and HIV-uninfected controls (N = 397). This study observed a reduction of limbic lobe, cingulate gyrus, frontal lobe, middle frontal gyrus, sub-lobar, insula, inferior frontal gyrus and superior frontal gyrus volume in HIV patients. These morphological differences may be responsible for cognitive decline in HIV patients, as these brain regions are closely related to motor and memory functions. These results contribute to a better understanding of the neural mechanisms underlying brain injury in HIV patients and could help develop targeted brain targets, provide more personalized treatment and predict neurodevelopmental outcomes.

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
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
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
We performed vertex-wise analyses comparing grey matter in youth with and without perinatally-acquired HIV (PHIV). PHIV youth had reduced cortical thickness, surface area, and gyrification compared to control youth. PHIV youth did not exhibit the same pattern of inverse grey matter-age relationships that were observed in control youth.
Youth with perinatally-acquired HIV (PHIV) experience specific and global cognitive deficits at increased rates compared to typically-developing HIV-uninfected youth. In youth with PHIV, HIV infects the brain early in development. Neuroimaging studies have demonstrated altered grey matter morphometry in youth with PHIV compared to typically-developing youth. This study examined cortical thickness, surface area, and gyrification of grey matter in youth (age 11–20 years old) with PHIV (n = 40) from the Pediatric HIV/AIDS Cohort Study (PHACS) compared to typically-developing presumed HIV uninfected and unexposed youth (n = 80) from the Pediatric Imaging, Neurocognition and Genetics Study (PING) using structural magnetic resonance imaging. This study also examined the relationship between grey matter morphometry and age. Youth with PHIV had reduced cortical thickness, surface area, and gyrification compared to typically-developing youth. In addition, an inverse relationship between age and grey matter volume was found in typically-developing youth, but was not observed in youth with PHIV. Longitudinal studies are necessary to understand the neurodevelopmental trajectory of youth with PHIV.

Abstract
There are an estimated 2.1 million youth less than 15 years of age living with HIV globally (the majority perinatally HIV-infected [PHIV]) and millions more perinatally HIV-exposed uninfected (PHEU) youth who are expected to survive through adolescence and into adulthood. Transitioning from adolescence to young adulthood requires adaptation to more demanding social interactions, academic pressures, and individual responsibilities which place distinct demands on neurocognitive functions. This study examined longitudinal trajectories of neurocognitive test performance in the domains of processing speed (PS), working memory (WM), and executive functioning (EF) among PHIV and demographically similar PHEU from adolescence through young adulthood. Data for this paper come from four time points, spanning approximately 10 years, within the Child and Adolescent Self-Awareness and Health Study (CASAH). Youth age ranged from 15 to 29 years. Longitudinal linear mixed effect models were computed for each test. Few differences in performance were found on tests of EF and WM between PHIV and PHEU youth as they aged, though PHEU youth showed significantly better PS as they aged than PHIV youth. Future research is needed to understand these vulnerable youth's neurocognitive trajectories as a function of HIV infection and -exposure, biological functions and psychosocial stressors.

Abstract
BACKGROUND Young adults living with perinatally acquired HIV infection (PHIVYAs) are at risk for poor biomedical and behavioral health outcomes. Few studies offer a comprehensive overview of the functioning of this population in young adulthood and the role of HIV. METHODS Data come from the Child and Adolescent Self-Awareness and Health Study, a longitudinal behavioral health cohort study of PHIVYAs and perinatally HIV-exposed but uninfected young adults (PHEUYAs) who are compared on psychiatric and neurocognitive functioning, sexual and substance use behaviors, health and reproductive outcomes, and young adult milestones. RESULTS Overall, 27% of participants met criteria for a psychiatric disorder, including mood (11%), anxiety (22%), and substance use (28%), with no HIV status differences. PHIVYAs performed worse on 2 neurocognitive tests. There were no HIV status differences in condomless sex (41%) or pregnancies (41% women; 38% men). Both groups exhibited similar adult milestones: 67% graduated high school or an equivalent, 19% were in college, and 42% were employed. However, 38% were neither in school or working, 12% reported incarceration, and 16% were ever homeless. Among PHIVYAs, 36% were viremic (>200 copies per mL), and 15% were severely immunocompromised (CD4+ cell count <100 cells per mm3). CONCLUSIONS Many PHIVYAs achieve adult milestones related to school, employment, sexual relationships, and starting families. However, they and PHEUYAs have high rates of psychiatric and substance use disorders and behavioral risks, which can jeopardize long-term health and adult functioning, particularly in the context of HIV. These findings underscore an urgent need to escalate interventions.

Abstract
Despite improved survival due to combination antiretroviral therapy (cART), youth with perinatally-acquired HIV (PHIV) show cognitive deficits and developmental delay at increased rates. HIV affects the brain during critical periods of development, and the brain may be a persistent reservoir for HIV due to suboptimal blood brain barrier penetration of cART. We conducted structural magnetic resonance imaging (sMRI) and cognitive testing in 40 PHIV youth (mean age=16.7years) recruited from the NIH Pediatric HIV/AIDS Cohort Study (PHACS) who are part of the first generation of PHIV youth surviving into adulthood. Historical and current HIV disease severity and substance use measures were also collected. Total and regional cortical grey matter brain volumes were compared to a group of 334 typically-developing, HIV-unexposed and uninfected youth (frequency-matched for age and sex) from the Pediatric Imaging, Neurocognition, and Genetics (PING) study (mean age=16.1years). PHIV youth had smaller (2.8-5.1%) total and regional grey matter volumes than HIV-unexposed and uninfected youth, with smallest volumes seen among PHIV youth with higher past peak viral load (VL) and recent unsuppressed VL. In PHIV youth, worse cognitive performance correlated with smaller volumes. This pattern of smaller grey matter volumes suggests that PHIV infection may influence brain development and underlie cognitive dysfunction seen in this population. Among PHIV youth, smaller volumes were also linked to substance use (alcohol use: 9.0-13.4%; marijuana use: 10.1-16.0%). In this study, collection of substance use information was limited to the PHIV cohort; future studies should also collect substance use information in controls to further address interactions between HIV and substance use on brain volume.
