Manaye M, Melese E, Wassie GT. The magnitude of neurocognitive disorders and associated factors among people living with HIV AIDS facilities in Bahir Dar City Ethiopia. Sci Rep 2024; 14:19058. [PMID: 39154066 PMCID: PMC11330510 DOI: 10.1038/s41598-024-68909-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2024] [Accepted: 07/29/2024] [Indexed: 08/19/2024] Open
Abstract
Neurocognitive disorders are mental health conditions that are caused by medical illnesses and can lead to several acquired cognitive deficits, which represent a decline from a previously attained level of functioning. The principal domains of cognitive functions include complex attention, executive function, learning and memory, language, perceptual-motor function, and social cognition. Studies have shown that people living with human immunodeficiency virus (HIV) are at a heightened risk of experiencing cognitive challenges across multiple domains. Given that, a substantial number of people live in Amhara region, assessing cognitive domains to estimate the current magnitude and factors associated with neurocognitive disorders among HIV/AIDS patients is crucial. An institutional-based cross-sectional study was conducted among 569 participants adults living with HIV attending the city's selected health facilities from March 20 to April 30, 2023. A multistage sampling technique was used. The International HIV Dementia Scale (IHDS) was used to measure the outcome of interest. The data were collected using a structured questionnaire and document review. The data were analyzed using STATA version 14. Multiple binary logistic regressions were used as the final model. A total of 501 individuals, with a response rate of 88.04% participated in the study. The overall proportion of HIV patients with neurocognitive impairment was 54.7% (95% CI 50.62-58.77). Factors associated with the neurocognitive impairment were: being widowed AOR = 3.05 (95% CI 1.47-6.31), divorced AOR = 1.95 (1.16-3.28), rural residence AOR = 2.28 (95% CI 1.02-5.09), CD4 count below 500 cells/dl AOR = 1.61 (95% CI 1.03-2.50), history of opportunistic infection AOR = 2.21 (95% CI 1.42-3.41), being in first-line drug regimen AOR = 2.92 (95% CI 1.22-7.00), being in a first-line regimen with Efavirenz AOR = 4.36 (95% CI 1.07-17.73), and impairment in daily living AOR = 2.64 (95% CI 1.39-4.99). In this study, the proportion of neurocognitive impairment was greater than that in most previous studies conducted in Ethiopia. The factors associated with the disorder were: being widowed or divorced, living in a rural area, having low CD4, having a history of opportunistic infection, receiving a first-line drug regimen, receiving efavirenz-containing drugs, and having impaired daily living. Hence, routine neuropsychological screenings should be integrated into comprehensive ART care by the regional health bureau and implemented by hospitals and health centers.

Abstract
OBJECTIVE To assess the prevalence and associated factors of neurocognitive disorder among people living with HIV/AIDS in South Gondar primary hospitals, North-West Ethiopia, 2023. DESIGN Institution-based cross-sectional study design. SETTING South Gondar primary hospitals, North-West Ethiopia. PARTICIPANTS 608 participants were recruited using the systematic random sampling technique. MEASUREMENT Data were collected using an interviewer-administered questionnaire and medical chart reviews. The International HIV Dementia Scale was used to screen for neurocognitive disorder. The data were entered through EPI-DATA V.4.6 and exported to SPSS V.21 statistical software for analysis. In the bivariable logistic regression analyses, variables with a value of p<0.25 were entered into a multivariable logistic regression analysis to identify factors independently associated with neurocognitive disorder. Statistical significance was declared at a value of p<0.05. RESULTS The prevalence of neurocognitive disorder among HIV-positive participants was 39.1%. In multivariable logistic regression, lower level of education (adjusted OR (AOR)=2.94; 95% CI 1.29 to 6.82), unemployment (AOR=2.74; 95% CI 1.29 to 6.84) and comorbid medical illness (AOR=1.80; 95% CI 1.03 to 3.14) were significantly associated with neurocognitive disorder. CONCLUSION HIV-associated neurocognitive problems affected over a third of the participants. According to the current study, comorbid medical conditions, unemployment and low educational attainment are associated with an increased risk of neurocognitive disorder. Therefore, early detection and treatment are essential.

Abstract
INTRODUCTION Depression is prevalent among aging people living with HIV (PLWH) worldwide. We sought to identify depression risk factors among a group of middle-aged and older PLWH in Lima, Peru. MATERIALS AND METHODS We assessed risk factors for depression among PLWH over age 40 receiving care in an HIV clinic in Lima, Peru. The Patient Health Questionnaire-9 (PHQ-9) was administered. We performed descriptive statistics and logistic regression analyses. RESULTS Mean age was 51.7 ± 7.7 years with 15.3% females. One-quarter of participants had depression with higher frequency in females. Risk factors that significantly increased the risk of depression included female sex (adjusted prevalence ratio [aPR] = 2.19 [95%CI 1.07-4.49]), currently smoking (aPR = 2.25 [95%CI 1.15-4.43]), and prior opportunistic infection (aPR = 2.24 [95%CI 1.05-4.76]). DISCUSSION Our study demonstrates that PLWH who are female, current smokers, or had an opportunistic infection have higher risk of depression. Identifying PLWH at-risk for depression is key to early mental health interventions.

Abstract
The modern combined antiretroviral treatment (cART) for human immunodeficiency virus (HIV) infection has substantially lowered the incidence of HIV-associated dementia (HAD). The dominant clinical features include deficits in cognitive processing speed, concentration, attention, and memory. As people living with HIV become older, with high rates of comorbidities and concomitant treatments, the prevalence and complexity of cognitive impairment are expected to increase. Currently, the management of HAD and milder forms of HAND is grounded on the best clinical practice, as there is no specific, evidence-based, proven intervention for managing cognitive impairment. The present article acknowledges the multifactorial nature of the cognitive impairments found in HIV patients, outlining the current concepts in the field of HAD. Major areas of interest include neuropsychological testing and neuroimaging to evaluate CNS status, focusing on greater reliability in the exclusion of associated diseases and allowing for earlier diagnosis. Additionally, we considered the evidence for neurological involvement in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and the impact of the coronavirus (COVID-19) pandemic, with wider consequences to population health than can be attributed to the virus itself. The indirect effects of COVID-19, including the increased adoption of telehealth, decreased access to community resources, and social isolation, represent a significant health burden, disproportionately affecting older adults with dementia who have limited social networks and increased functional dependence on the community and health system. This synopsis reviews these aspects in greater detail, identifying key gaps and opportunities for researchers and clinicians; we provide an overview of the current concepts in the field of HAD, with suggestions for diagnosing and managing this important neurological complication, which is intended to be applicable across diverse populations, in line with clinical observations, and closely representative of HIV brain pathology.

Sex Differences in the Cognitive Performance of a South African Cohort of People With HIV and Comorbid Major Depressive Disorder. J Int Assoc Provid AIDS Care 2023; 22:23259582231203192. [PMID: 37787183 PMCID: PMC10548808 DOI: 10.1177/23259582231203192] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Revised: 07/02/2023] [Accepted: 09/05/2023] [Indexed: 10/04/2023] Open
Abstract
Women with HIV (WWH) may be more vulnerable to cognitive impairment than men with HIV (MWH), which may be explained by the direct effects of HIV or by sociodemographic and psychiatric characteristics. We recruited 105 people with HIV (PWH; 76 women) with incomplete antiretroviral therapy adherence, comorbid major depressive disorder, and socioeconomically disadvantaged backgrounds. Participants completed neuropsychological testing and measures gathering sociodemographic, medical, and psychiatric information. We compared WWH and MWH cognitive performance using unadjusted and adjusted regressions, and within each respective group, we explored predictors of cognitive performance. Results showed no significant between-sex differences in cognitive performance, both globally and within domains. Fewer years of education (β = 0.94), illiteracy (β = 4.55), and greater food insecurity (β = -0.28) predicted lower cognitive performance in WWH but not MWH. We conclude that sex differences in PWH are likely due to sample characteristics representing broader inequalities, rather than true biological differences.

Abstract
Understanding the effect of the HIV, HTLV-1, and HCV viruses on cognitive aspects can help in the better characterization of dementia, as well as the best conducts to be suitable for rehabilitation. Thus, the present study aimed to characterize and compare the neuropsychological profile of 3 groups of patients with infectious diseases: HIV, HTLV, and HCV. The results of neuropsychological assessments and depression assessment of 325 people treated at a referral hospital for infectious diseases were analyzed, being 120 HIV carriers (74 (61.7%) men) with an average age of 47.5 years (SD = 10.3), 65 patients with HTLV-1 (16 (24.6%) men) with a mean age of 49.9 years (SD = 12.9), and 87 HCV patients (47 (54%) men) with a mean age of 55.5 years (SD = 11.2). In addition, 54 people (26 (48.1%) men) with negative serology who made up the control group were evaluated. The results of the statistical evaluation of the sociodemographic factors of the four groups (HIV, HTLV-1, HCV, and control) showed that in addition to age, schooling was a significant factor among them and may have a strong influence on the performance of cognitive tests. The HTLV-1 group had the lowest neurocognitive performance and also the highest rate of depressive symptoms.

Abstract
Depression is the leading cause of years lived with disability worldwide and PLWHIV present a higher risk of developing depressive symptoms. We aimed to evaluate depressive symptoms and their predictors in virologically suppressed PLWHIV. We conducted a cross-sectional study with 200 PLWHIV. Depressive symptoms were defined as scoring ≥ 14 points in the Beck Depression Inventory II. Most of the participants (58.5%) were men, with a median age of 54 years (IQR: 46.25-59.00). Depressive symptoms' prevalence was 19.5% and they were associated with being divorced/widowed (aOR: 2.93, CI 95%: 1.17-7.37), recurrent falls (aOR: 4.24, CI 95%: 1.07-16.85), pre-frailty (aOR: 3.55, CI 95%: 1.47-8.57), and lower scores in all HRQoL dimensions. Although virologically suppressed PLWHIV presented lower prevalence of depressive symptoms than reported in previous studies in Brazil and South America, they were associated with falls and frailty, highlighting the need for screening.

Abstract
BACKGROUND Neurocognitive impairment is associated with psychological morbidities, such as depression and anxiety, among people living with HIV. The presence of these comorbidities affects viral load suppression, treatment adherence, quality of life, treatment outcomes, and functionality. Despite this fact, there is a dearth of studies that examined the triple burden of neurocognitive impairment and co-occurring depression and anxiety among antiretroviral therapy attendees in Ethiopia. This study aimed to assess the magnitude of HIV-associated neurocognitive impairment and co-occurring depression and anxiety at the same time among people living with HIV/AIDS. METHOD We conducted an institution-based multicenter cross-sectional study in Bahir Dar, Northwest Ethiopia. A total of 410 study participants were selected using a systematic random sampling technique. Neurocognitive impairment was assessed using the International HIV Dementia Scale. Co-occurring depression and anxiety were assessed using the Hospital Anxiety and Depression Scale. A semi-structured questionnaire was applied to collect data on sociodemographic and clinical-related characteristics. Data were analyzed using descriptive statistics and univariate and multivariable logistic regression. RESULTS Two-thirds (66.8%) of the people living with HIV had neurocognitive impairment. The prevalence of co-occurring depression and anxiety was found in 39.8%. Women with HIV, people with comorbid chronic medical illness, and those under a second-line treatment regimen were factors associated with neurocognitive impairment. Furthermore, pill burden, second-line treatment regimen, HIV clinical stages, social support, HIV-perceived stigma, and neurocognitive impairment were associated factors with co-occurring depression and anxiety. CONCLUSIONS We found a high prevalence of neurocognitive impairment and co-occurring depression and anxiety among people living with HIV/AIDs. Further research is needed to assess the clinical course of neurocognitive impairment and co-occurring depression and anxiety.

Abstract
HIV-associated neurocognitive impairment remains a challenge even in the era of antiretroviral therapy (ART). Over 90% of people living with HIV are in low- and middle-income countries. Hence, it is not surprising that such countries bear a considerable burden of comorbidities like HIV-associated neurocognitive impairment despite an overall increase in life expectancy. The literature suggests differences in patient characteristics, clinical profile, prevalent HIV subtypes, treatment choices, pharmacogenetics, and socioeconomic factors between low- and middle-income countries compared with high-income countries. Therefore, we aimed to evaluate the effect of ART on neurocognitive outcomes in low- and middle-income countries. A comprehensive search of five databases (PubMed, CINAHL, CENTRAL, PsychInfo, Google scholar) for studies published between 1996 to 2020 was performed to identify studies that reported neurocognitive outcomes in ART-treated and ART naïve HIV positive individuals. Two independent reviewers conducted study screening, data extraction, and evaluation of the risk of bias. Pooled effect size estimates (Hedges' g) and 95% CI were computed using random-effects models. Sensitivity analysis, subgroup analysis, meta-regression, and evaluation of publication bias were also conducted. Forty studies (24 cross-sectional, 13 longitudinal studies, and two randomized controlled trials) contributed to a series of meta-analyses. We found significant small to moderate effects of antiretroviral therapy for global cognition (Hedges' g observed = 0.30; 95% CI: 0.15, 0.44; k = 25; p = 0.0003; I2 = 92.1%; tau = 0.32; Q = 305.1), executive function (Hedges' g = 0.24, 95%CI: 0.02,0.46; p-0.04; k = 8; I2 = 37.5%; tau = 0.23; Q = 11.2), and speed of information processing (Hedges' g = 0.25, 95% CI: 0.05, 0.45; k = 9; p = 0.02; I2 = 86.4%; tau = 0.21; Q = 58.9). We found no significant ART effect on attention-working memory, learning and memory, motor function, and verbal fluency. No significant effect was seen with the duration of therapy, efavirenz use, and Central Penetrating Effectiveness (CPE) of antiretroviral therapy. Subgroup analyses identified study design (between-group and within-group; cross-sectional and longitudinal) and normative scores as significant sources of heterogeneity. Meta-regression analysis indicated that nadir CD4 modified the magnitude of ART's effect on cognitive outcomes. Age, gender, and country income-group were not significant moderators. Our findings provide systematic evidence that antiretroviral therapy improves neurocognitive outcomes in the domains of global cognition, executive function and speed of information processing, of people living with HIV in low- and middle-income countries, especially those with advanced immunosuppression. However, these findings are not definitive as they are limited by the probability of publication bias, high heterogeneity, and exclusion of significant confounders.

Abstract
OBJECTIVE Although many studies report that women with HIV (WWH) are more vulnerable to cognitive impairment than men with HIV (MWH), this trend is not described consistently in the literature. In this systematic review and meta-analysis, we investigated whether the weight of evidence supports the existence of a significant sex difference in cognitive functioning among people with HIV and, if so, whether specific domains are affected. METHOD A systematic literature search retrieved 4,062 unique articles published between January 2000 and June 2019. Eligibility criteria were that studies directly compared adult WWH and MWH using a neuropsychological test battery. After extensive screening, we included 11 studies in the systematic review (N = 3,333) and 6 in the meta-analysis (N = 2,852). RESULTS Six studies included in the systematic review found WWH performed significantly more poorly on measures of cognitive performance than MWH; the other five found no sex differences. Meta-analytic results indicated that WWH performed significantly more poorly than MWH in three cognitive domains (psychomotor coordination, visuospatial learning, and memory), but magnitudes of effect sizes were small (d = -.16, -.43, and - .30, respectively). Analyses detected no sex differences in global cognitive functioning and in the other cognitive domains. CONCLUSIONS Sex differences in cognitive performance are small, and sociodemographic and psychiatric characteristics of WWH and MWH differ between studies. Cognitive differences between WWH and MWH may be explained by sex-based variation in these characteristics, the impact of which seems to outweigh that of HIV-related clinical variables (e.g., CD4 count and viral load).

Abstract
Long-term effective use of antiretroviral therapy (ART) among people with HIV (PWH) has significantly reduced the burden of disease, yet a cure for HIV has not been universally achieved, likely due to the persistence of an HIV reservoir. The central nervous system (CNS) is an understudied HIV sanctuary. Importantly, due to viral persistence in the brain, cognitive disturbances persist to various degrees at high rates in PWH despite suppressive ART. Given the complexity and accessibility of the CNS compartment and that it is a physiologically and anatomically unique immune site, human studies to reveal molecular mechanisms of viral entry, reservoir establishment, and the cellular and structural interactions leading to viral persistence and brain injury to advance a cure and either prevent or limit cognitive impairments in PWH remain challenging. Recent advances in human brain organoids show that they can mimic the intercellular dynamics of the human brain and may recapitulate many of the events involved in HIV infection of the brain (neuroHIV). Human brain organoids can be produced, spontaneously or with addition of growth factors and at immature or mature states, and have become stronger models to study neurovirulent viral infections of the CNS. While organoids provide opportunities to study neuroHIV, obstacles such as the need to incorporate microglia need to be overcome to fully utilize this model. Here, we review the current achievements in brain organoid biology and their relevance to neuroHIV research efforts.

Characterization of HIV-Associated Neurocognitive Impairment in Middle-Aged and Older Persons With HIV in Lima, Peru. Front Neurol 2021; 12:629257. [PMID: 34220665 PMCID: PMC8248346 DOI: 10.3389/fneur.2021.629257] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2020] [Accepted: 04/21/2021] [Indexed: 12/12/2022] Open
Abstract
Background: With widespread use of antiretroviral medications, people living with HIV (PWH) are living longer worldwide, increasing their risk of developing neurocognitive impairment (NCI). The proportion of Peruvians over age 60 is expected to increase to 25% of the population by 2050, including PWH. Therefore, the problem of aging and NCI, especially in the setting of HIV infection, is uniquely pressing. We sought to study the rates of and risk factors associated with NCI among middle-aged and older PWH in Lima, Peru. Materials and Methods: Sociodemographic, medical (infectious and non-infectious), and psychiatric comorbidity and laboratory data were collected. We administered a brief neuropsychological battery evaluating seven cognitive domains affected in HIV-associated NCI and a depression screening. Cognitive test raw scores were converted to T-scores that were demographically adjusted. Descriptive statistics were performed together with regression (unadjusted and adjusted) analyses to determine potential risk factors for NCI among PWH. Results: This was a cross-sectional study in which 144 PWH aged ≥40 years attending a large HIV clinic in Lima, Peru, were recruited from September 2019 to March 2020. Mean age was 51.6 ± 7.7 years, and mean years of education were 14.0 ± 3.1 with 15% females. Median [interquartile range (IQR)] current CD4 and nadir CD4 were 554 (371, 723) and 179 (83, 291), respectively, and 10% currently had AIDS. The prevalence of NCI was 28.5%, and many demonstrated difficulty with attention and working memory (70%). One-quarter of PWH had mild depression or worse on Patient Health Questionnaire 9 (PHQ-9 ≥ 5). In bivariate analyses, neither a depression history nor a higher PHQ-9 score correlated with NCI. No other non-communicable medical or psychiatric comorbidity nor HIV characteristic was predictive of NCI. Having a positive lifetime history of hepatitis B infection, pulmonary tuberculosis, or syphilis increased risk of NCI (PR 1.72; 95% CI 1.04-2.86) in unadjusted analyses, but not in adjusted analyses. Conclusions: NCI among older Peruvians with HIV was found to be highly prevalent with levels consistent with prior reports of HIV-associated NCI worldwide. Common latent HIV-associated co-infections, including latent syphilis, hepatitis B infection, or pulmonary tuberculosis, may increase the risk of NCI among middle-aged and older PWH in Peru.

Abstract
Quality of life (QoL) is recognized as an essential end point in the disease management of chronic conditions such as HIV with calls to include good QoL as a ‘fourth 90’ in the 90-90-90 testing and treatment targets introduced by World Health Organization in 2016. Cognitive impairments impact a broad spectrum of experiences and are a common issue effecting people living with HIV (PLWH). Despite this, few studies have examined QoL in PLWH who also have a cognitive disorder. This study aimed to synthesize and describe what is known about QoL in those living with HIV-associated neurocognitive disorders (HAND). A scoping review of peer-reviewed literature was conducted to identify how QoL has been investigated and measured in PLWH with HAND, and how PLWH with HAND report and describe their QoL. We searched PsychInfo, Medline, Scopus, and Web of Science along with hand-searching reference lists from relevant studies found. Included studies were those published in English after 1st January 2003 which included PLWH with cognitive impairment not due to other pre-existing conditions. Fifteen articles met criteria for inclusion. Two studies measured QoL as a primary aim, with others including QoL assessment as part of a broader battery of outcomes. The MOS-HIV and SF-36 were the most commonly used measures of overall QoL, with findings generally suggestive of poorer overall QoL in PLWH with HAND, compared to PLWH without cognitive impairment. Studies which examined dimensions of QoL focused exclusively on functionality, level of independence, and psychological QoL domains. There is a considerable dearth of research examining QoL in PLWH with HAND. The initiatives which advocate for healthy aging and improved QoL in PLWH must be extended to include and understand the experiences those also living with cognitive impairment. Research is needed to understand the broad experiential impacts of living with these two complex, chronic conditions, to ensure interventions are meaningful to patients and potential benefits are not missed.

The Impact of Antiretroviral Therapy on Neurocognitive Outcomes Among People Living with HIV in Low- and Middle-Income Countries (LMICs): A Systematic Review. AIDS Behav 2021; 25:492-523.

Abstract
Low and middle-income countries (LMICs) are the epicenter of the HIV epidemic. The scale-up of antiretroviral therapy (ART) has reduced mortality, but HIV-associated neurocognitive impairment (HANI) remains prevalent, which impacts functional performance, medication adherence, and quality of life. We aimed to evaluate the effect of ART on neurocognitive outcomes among people living with HIV/AIDS in LMICs and to identify determinants of these outcomes. We searched electronic databases and reference lists for studies published between 1996 and 2019. Two reviewers screened the primary studies for inclusion and performed the critical appraisal. Results were synthesized using the 'Synthesis without meta-analysis' approach through simple vote counting. We identified 31 studies conducted across four regions (Africa, Asia, South America, and Eastern Europe). Nine studies were cross-sectional, 15 were prospective, and seven were randomized controlled trials. The majority of the articles showed improved neurocognitive performance with ART use but found no association with treatment duration, regimen, central penetrating effectiveness, and conventional biomarkers. Despite the lack of appropriate norms and not accounting for practice effect in most studies, the evidence suggests ART is useful in the treatment of HIV-associated neurocognitive impairment (HANI) but limited in addressing legacy effects, and peripheral, and central viral reservoirs. Improved early ART treatment programs, viral reservoir eradication strategies, and identification of novel biomarkers will be critical in efforts to minimize HIV-associated neurocognitive impairment.

Abstract
PURPOSE OF REVIEW With the establishment of antiretroviral treatment (ART) programs in low- and middle-income countries, people with HIV (PWH) in Latin America and the Caribbean (LAC) are living longer, subsequently developing chronic non-communicable diseases (NCDs). Few studies focus on the impact of aging among older LAC PWH. This systematic review aims to fill this information gap and understand the burden of aging with HIV in LAC. We identified peer-reviewed literature published in English, Spanish, or Portuguese from several databases to assess currently available evidence on the burden of aging with HIV in LAC and selected six common NCDs found in older PWH (cardiovascular disease [CVD], bone and musculoskeletal [MSK] disorders, cancer, renal disease, neurocognitive impairment [NCI], and depression). RECENT FINDINGS Of the 5942 publications reviewed, only 53 articles were found with populations 40 years and older or age-related findings (27 CVD, 13 NCI or depression, 6 MSK disorders, 4 renal disease, 3 cancer). Most (79%) publications were from Brazil with few longitudinal studies on aging with HIV. Prevalence of illnesses such as CVD, NCI, depression, or osteoporosis varied widely depending on the screening instrument utilized and geographic population surveyed. Age was a significant predictor of comorbidity in nearly all studies. Our results demonstrate the need for longitudinal studies and validated screening instruments appropriate for use among PWH in LAC. Understanding the mechanisms behind aging in HIV and the roles of sociocultural factors and genetic diversity specific to LAC is needed to appropriately manage chronic comorbidities as PWH age.

Abstract
In the era of antiretroviral treatment, human immunodeficiency virus (HIV)-associated neurocognitive disorder (HAND) is common in HIV-positive (HIV+) patients, with an incidence of 30-50%. The relationship between education level and HAND has been evaluated in some studies, however, the results were inconsistent. The aim of this meta-analysis was to provide compelling evidence on the association between education level and the risk of HAND. Reports were searched for in the databases of Medline, Embase and PsyclNFO. Studies evaluating the relationship between education level and HAND in adult HIV+ patients were included. The pooled odds ratio/risk ratio was analysed by using the random-effects model. Two subgroup analyses were performed according to the adjustment of educational level in the neurocognitive impairment assessment and the income level. In total, 18 studies were included. Six studies and 12 studies reported education level as the continuous variable and categorical variable, respectively. The methods used for the assessment of neurocognitive impairment in included studies were neuropsychological battery tests (n = 10), HIV Dementia Scale (n = 1), the International HIV Dementia Scale (n = 6) and the Chinese version of the Montreal Cognitive Assessment (n = 1). The result showed that the risk of HAND in HIV+ patients who have lower education attainment was significantly higher than that in HIV+ patients who have higher education attainment. In conclusion, this meta-analysis demonstrated that HIV+ patients who have low education attainment carry higher risk of developing HAND compared with HIV+ patients who have high education attainment. This study highlighted the importance of early neurological screening for HIV+ patients who have low education level.

Abstract
Despite advancements in antiretroviral therapy, mild cognitive deficits persist in nearly half of people with HIV (PWH). The profile of impairment in HIV is highly variable with deficits observed in a range of cognitive domains. Despite evidence of greater cognitive impairment among women with HIV (WWH) vs. men with HIV (MWH), it is unclear how MWH and WWH differ in the type of cognitive impairment and in risk factors associated with cognitive impairment profiles. In a large and well-characterized sample of PWH, we used machine learning to identify profiles of cognitive functioning and their associated factors overall and within sex. Participants included 1,666 PWH (201 WWH; 1,465 MMH) from the HIV Neurobehavioral Research Program who completed a neuropsychological test battery at their baseline visits. Using demographically-adjusted T-scores from 13 test outcomes assessing motor skills, executive functioning, attention/working memory, episodic learning and memory, verbal fluency, and processing speed, we used Kohonen self-organizing maps to identify patterns of high-dimensional data by mapping participants to similar nodes based on T-scores (MCLUST R package). Random forest models were used to determine how sociodemographic (e.g., age, education), clinical (e.g., depressive symptoms, substance use disorder), and biological (e.g., HIV disease characteristics) factors differentially related to membership within a cognitive profile. All analyses were repeated within sex. Three cognitive profiles were identified overall and within each sex. Overall and within MWH, there were unimpaired and global weakness profiles. The third profile in the total sample demonstrated relatively weak auditory attention whereas in MWH showed relative strengths in attention and processing speed. Conversely, there was no unimpaired profile among WWH. Rather, WWH demonstrated separate profiles reflecting weakness in motor skills, a relative weakness in learning and delayed recall, and global weaknesses with spared recognition memory. Despite different cognitive profiles by sex, the most discriminative factors were similar between men and women and included reading level (cognitive reserve), current and nadir CD4 count, plasma HIV viral load, duration of HIV disease, age, depressive symptoms, and race/ethnicity. Findings fill a knowledge gap concerning sex differences in cognitive impairment in PWH and inform personalized risk reduction and therapeutic strategies.

Abstract
Antiretroviral therapy (ART) has transformed HIV into a chronic condition, lengthening and improving the lives of individuals living with this virus. Despite successful suppression of HIV replication, people living with HIV (PLWH) are susceptible to a growing number of comorbidities, including neuroHIV that results from infection of the central nervous system (CNS). Alterations in the dopaminergic system have long been associated with HIV infection of the CNS. Studies indicate that changes in dopamine concentrations not only alter neurotransmission, but also significantly impact the function of immune cells, contributing to neuroinflammation and neuronal dysfunction. Monocytes/macrophages, which are a major target for HIV in the CNS, are responsive to dopamine. Therefore, defining more precisely the mechanisms by which dopamine acts on these cells, and the changes in cellular function elicited by this neurotransmitter are necessary to develop therapeutic strategies to treat neuroHIV. This is especially important for vulnerable populations of PLWH with chemically altered dopamine concentrations, such as individuals with substance use disorder (SUD), or aging individuals using dopamine-altering medications. The specific neuropathologic and neurocognitive consequences of increased CNS dopamine remain unclear. This is due to the complex nature of HIV neuropathogenesis, and logistical and technical challenges that contribute to inconsistencies among cohort studies, animal models and in vitro studies, as well as lack of demographic data and access to human CNS samples and cells. This review summarizes current understanding of the impact of dopamine on HIV neuropathogenesis, and proposes new experimental approaches to examine the role of dopamine in CNS HIV infection. Graphical abstract HIV Neuropathogenesis in the Presence of a Disrupted Dopamine System. Both substance abuse disorders and the use of dopaminergic medications for age-related diseases are associated with changes in CNS dopamine concentrations and dopaminergic neurotransmission. These changes can lead to aberrant immune function, particularly in myeloid cells, which contributes to the neuroinflammation, neuropathology and dysfunctional neurotransmission observed in dopamine-rich regions in HIV+ individuals. These changes, which are seen despite the use antiretroviral therapy (ART), in turn lead to further dysregulation of the dopamine system. Thus, in individuals with elevated dopamine, the bi-directional interaction between aberrant dopaminergic neurotransmission and HIV infection creates a feedback loop contributing to HIV associated neurocognitive dysfunction and neuroHIV. However, the distinct contributions and interactions made by HIV infection, inflammatory mediators, ART, drugs of abuse, and age-related therapeutics are poorly understood. Defining more precisely the mechanisms by which these factors influence the development of neurological disease is critical to addressing the continued presence of neuroHIV in vulnerable populations, such as HIV-infected older adults or drug abusers. Due to the complexity of this system, understanding these effects will require a combination of novel experimental modalities in the context of ART. These will include more rigorous epidemiological studies, relevant animal models, and in vitro cellular and molecular mechanistic analysis.

The Prevalence of Frascati-Criteria-Based HIV-Associated Neurocognitive Disorder (HAND) in HIV-Infected Adults: A Systematic Review and Meta-Analysis. Front Neurol 2020; 11:581346. [PMID: 33335509 PMCID: PMC7736554 DOI: 10.3389/fneur.2020.581346] [Citation(s) in RCA: 68] [Impact Index Per Article: 17.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2020] [Accepted: 11/09/2020] [Indexed: 12/12/2022] Open
Abstract
Background: The HIV associated mortality is decreasing in most countries due to the widespread use of antiretroviral therapy. However, HIV-associated neurocognitive disorder (HAND) remains a problematic issue that lowers the quality of life and increases the public health burden among people living with HIV. The prevalence of HAND varies across studies and selected samples. Therefore, we aimed to quantitatively summarize the pooled prevalence of Frascati-criteria-based HAND and to explore the potential demographic, clinical, and immunological factors. Methods: A comprehensive literature search in PubMed/Medline, Web of Science, Embase, and PsycINFO was performed. A random-effects meta-analysis was conducted using the event rate (ER) for the estimation of the incidence of HAND. Subgroup meta-analyses were used to evaluate between-group differences in categorical variables. Meta-regression with the unrestricted maximum likelihood (ML) method was used to evaluate associations of continuous variables. Results: Eighteen studies whose sample sizes ranged from 206 to 1555 were included in the final analyses. The estimated prevalence of HAND, ANI, MND and HAD were 44.9% (95% CI 37.4-52.7%), 26.2% (95% CI 20.7-32.7%), 8.5% (95% CI 5.6-12.7%), 2.1% (95% CI 1.2-3.7%), respectively. Factors associated with HAND were percent female, current CD4 count, education level and country development level (all ps < 0.05). Conclusion: Longitudinal cohort and multimodal neuroimaging studies are needed to verify the clinical prognosis and the underlying neurocognitive mechanism of HAND. In addition, it is urgently necessary to establish a standardized HAND diagnostic process.

Abstract
OBJECTIVES HIV-associated neurocognitive disorder (HAND), although prevalent, remains a poorly researched cause of morbidity particularly in sub-Saharan Africa (SSA). We aimed to explore the risk factors for HAND in people aged 50 and over under regular follow-up at a government HIV clinic in Tanzania. METHODS HIV-positive adults aged 50 years and over were approached for recruitment at a routine HIV clinic appointment over a 4-month period. A diagnostic assessment for HAND was implemented, including a full medical/neurological assessment and a collateral history from a relative. We investigated potential risk factors using a structured questionnaire and by examination of clinic records. RESULTS Of the cohort (n = 253), 183 (72.3%) were female and the median age was 57 years. Fifty-five individuals (21.7%) met the criteria for symptomatic HAND. Participants were at a greater risk of having symptomatic HAND if they lived alone [odds ratio (OR) = 2.566, P = .015], were illiterate (OR 3.171, P = .003) or older at the time of HIV diagnosis (OR = 1.057, P = .015). Age was correlated with symptomatic HAND in univariate, but not multivariate analysis. CONCLUSIONS In this setting, HIV-specific factors, such as nadir CD4 count, were not related to symptomatic HAND. The "legacy theory" of early central nervous system damage prior to initiation of anti-retroviral therapy initiation may contribute, only in part, to a multifactorial aetiology of HAND in older people. Social isolation and illiteracy were associated with symptomatic HAND, suggesting greater cognitive reserve might be protective.

Abstract
High rates of cognitive disorders in antiretroviral-treated people living with HIV have been described worldwide. The exact prevalence of such cognitive disorders is determined by the definitions used, and the presence of these cognitive disorders significantly impacts the overall wellbeing of people with HIV. With the cohort of people with HIV becoming increasingly older, and having high rates of comorbidities and concomitant medication use, rates of cognitive disorders are likely to increase. Conversely, interventions are being sought to reduce the size of the latent HIV reservoir. If successful, such interventions are likely to also reduce the HIV reservoir in the brain compartment, which could result in improvements in cognitive function and reduced rates of impairment.

Abstract
PURPOSE OF REVIEW Mental health disorders, especially depression, are prevalent among people living with HIV (PLWH) and are associated with cognitive impairment (CI) among HIV-uninfected (HIV-) individuals. We conducted a comprehensive review of the link between depression and cognition among PLWH. RECENT FINDINGS Studies examining depression and cognition in PLWH report high rates of current (median = 24%) and lifetime depression (42%). There is reliable evidence that depression is associated with overall CI among PLWH, and in the cognitive domains of processing speed, executive function, learning and memory, and motor function. Although few studies have examined the interaction between HIV serostatus and depression on CI, there is no evidence of a stronger association between CI and depression in PLWH compared with HIV- controls. Depression is prevalent and reliably associated with CI in PLWH, with an overall pattern of domain-specific associations similar to that of HIV- individuals.

Abstract
PURPOSE OF REVIEW Sex differences in cognitive function are well documented yet few studies had adequate numbers of women and men living with HIV (WLWH; MLWH) to identify sex differences in neurocognitive impairment (NCI) and the factors contributing to NCI. Here, we review evidence that WLWH may be at greater risk for NCI. RECENT FINDINGS We conducted a systematic review of recent studies of NCI in WLWH versus MLWH. A power analysis showed that few HIV studies have sufficient power to address male/female differences in NCI but studies with adequate power find evidence of greater NCI in WLWH, particularly in the domains of memory, speed of information processing, and motor function. Sex is an important determinant of NCI in HIV, and may relate to male/female differences in cognitive reserve, comorbidities (mental health and substance use disorders), and biological factors (e.g., inflammation, hormonal, genetic).

Abstract
BACKGROUND Combination antiretroviral therapy (ART) improves HIV-associated neurocognitive disorder (HAND) stage in the United States where subtype B predominates, but the effect of ART and subtype on HAND stage in individuals in Uganda with subtypes D and A is largely unknown. SETTING A community-based cohort of participants residing in Rakai, Uganda. METHODS Three hundred ninety-nine initially ART-naive HIV-seropositive (HIV+) individuals were followed up over 2 years. Neurological and neuropsychological tests and functional assessments were used to determine HAND stage. Frequency and predictors of HAND and HIV-associated dementia (HAD) were assessed at baseline and at follow-up after ART initiation in 312 HIV+ individuals. HIV subtype was determined from gag and env sequences. RESULTS At 2-year follow-up, HAD frequency among HIV+ individuals on ART (n = 312) decreased from 13% to 5% (P < 0.001), but the overall frequency of HAND remained unchanged (56%-51%). Subtype D was associated with higher rates of impaired cognition (global deficit score ≥ 0.5) compared with HIV+ individuals with subtype A (55% vs. 24%) (P = 0.008). Factors associated with HAD at baseline were older age, depression, and plasma HIV viral load >100,000 copies/mL. At follow-up, age and depression remained significantly associated with HAD. CONCLUSIONS HIV+ individuals on ART in rural Uganda had a significant decrease in the frequency of HAD, but HAND persists after 2 years on ART. The current guideline of immediate ART initiation after HIV diagnosis is likely to greatly reduce HAD in sub-Saharan Africa. Further studies of the effect of HIV subtype and neurocognitive performance are warranted.

Abstract
Introduction: Despite advances in treatment, opportunistic infections are the major cause of morbidity and mortality among patients with the human immunodeficiency virus (HIV).
Objectives: To estimate the prevalence of opportunistic infections among insured HIV patients, and to establish its association with socio-demographic and clinical factors.
Materials and methods: This was an observational study with an analytical focus. We analysed 37,325 records of insured people with HIV. A bivariate analysis using chi square and ANOVA, adjusted by Bonferroni, and multiple logistic regression for the adult population were carried out to explore the association among any opportunistic infections as the response variable and socio-demographic and clinical factors.
Results: From the total, at least 18% experienced an opportunistic infection. The most frequent were tuberculosis and brain toxoplasmosis for adults, and pneumonia and diarrhea for patients under 13 years of age. The prevalence of any opportunistic infection was significantly higher in men (OR=1.5; CI95% 1.4-1.6), in those more than 40 years of age (OR=1.6; CI95% 1.3-2.0), in people subjected to forced displacement (OR=1.7; CI95% 1.5-1.9), and in those belonging to the subsidized or exception health affiliation regimes (OR= 2.7; CI95% 2.1-3.4). Regarding clinical factors, opportunistic infections were significantly associated to time since diagnosis (>10 years) (OR=1.6; CI95% 1.5-1.7), administration of antiretroviral treatment (OR=4.4; CI95% 3.9-5.1), and discontinuity of treatment (OR=1.7; CI95% 1.6-1.8). The multivariate analysis for adults in clinical stage A showed similar results.
Conclusions: Despite the preventable nature of opportunistic infections, their prevalence is high and they predominantly affect the most disadvantaged people.

Abstract
We examined the efficacy of psychological adherence-enhancing interventions (AEIs) compared with usual care in HIV-infected adults under antiretroviral treatment (ART) by focusing on adherence and clinical HIV markers as outcomes in the short term and long term. We searched relevant databases for controlled studies that compared psychological AEIs with usual care. We included 31 comparisons from 27 individual studies in our meta-analyses. Psychological AEIs were significantly superior to usual care in improving adherence [standardized mean difference (SMD) 0.30, 95% CI 0.20-0.40] and reducing HIV viral load (SMD 0.15, 0.07-0.23) at the end of treatment. At the last follow-up, we found no difference between psychological AEIs and usual care, neither on adherence (SMD 0.07, -0.11-0.24) nor on clinical markers (SMD 0.06, -0.03-0.15). After excluding outliers from the analyses, between-study heterogeneity was small, and we did not identify any relevant moderators of intervention effects. In summary, psychological AEIs may significantly improve ART adherence and HIV viral load compared with usual care in the short term, but fail to be superior in achieving long-lasting improvements on ART adherence and clinical HIV markers as compared with usual care. Owing to limited quality and the majority of studies being conducted in the United States or Europe, our results have to be interpreted with caution, and are most relevant to the United States and Europe. The consistently reported difficulties to achieve sustained ART adherence improvements in previous and the present meta-analyses highlight the need to focus on maintaining ART adherence improvements in future research.
