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
Studies of depression and its outcomes in older people living with HIV (PLWH) are currently lacking in sub-Saharan Africa. This study aims to investigate the prevalence of psychiatric disorders in PLWH aged ≥ 50 years in Tanzania focussing on prevalence and 2-year outcomes of depression. PLWH aged ≥ 50 were systematically recruited from an outpatient clinic and assessed using the Mini-International Neuropsychiatric Interview (MINI). Neurological and functional impairment was assessed at year 2 follow-up. At baseline, 253 PLWH were recruited (72.3% female, median age 57, 95.5% on cART). DSM-IV depression was highly prevalent (20.9%), whereas other DSM-IV psychiatric disorders were uncommon. At follow-up (n = 162), incident cases of DSM-IV depression decreased from14.2 to 11.1% (χ2: 2.48, p = 0.29); this decline was not significant. Baseline depression was associated with increased functional and neurological impairment. At follow-up, depression was associated with negative life events (p = 0.001), neurological impairment (p < 0.001), and increased functional impairment (p = 0.018), but not with HIV and sociodemographic factors. In this setting, depression appears highly prevalent and associated with poorer neurological and functional outcomes and negative life events. Depression may be a future intervention target.

The Role of Depressive Symptoms and Physical Activity Levels in Mediating the Association Between HIV Status and Neurocognitive Functions Among Individuals Aged at Least 50 Years in China: Cross-sectional Study. JMIR Public Health Surveill 2022; 8:e32968. [PMID: 35984684 PMCID: PMC9440416 DOI: 10.2196/32968] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2021] [Revised: 06/13/2022] [Accepted: 06/26/2022] [Indexed: 01/22/2023] Open
Abstract
BACKGROUND Neurocognitive impairments are prevalent among older people in China. It is more problematic among older people living with HIV. OBJECTIVE This study aims to compare neurocognitive performance between older people living with HIV and HIV-negative controls, and to explore whether the association between HIV status and neurocognitive performance was mediated by depressive symptoms and level of physical activity. METHODS A cross-sectional study was conducted in Yongzhou, China. All people living with HIV aged ≥50 years listed in the registry were invited. Frequency matching was used to sample HIV-negative controls from the general population according to the distribution of age, sex, and years of formal education of older people living with HIV. A total of 315 older people living with HIV and 350 HIV-negative controls completed the face-to-face interview and comprehensive neuropsychological assessment of seven domains (learning, memory, working memory, verbal fluency, processing speed, executive function, and motor skills). RESULTS As compared to HIV-negative controls, older people living with HIV performed worse in global score and all seven domains (P<.05). HIV infection was associated with higher depressive symptoms (P<.001) and lower level of physical activity (P<.001). Depressive symptoms and physical activity were negatively correlated (P<.001). Depressive symptoms and level of physical activity mediated the association between HIV status and global z-score and four domain z-scores of neurocognitive performance (learning, memory, verbal fluency, and processing speed). CONCLUSIONS Change in mental health and physical activity after HIV infection may partially explain why older people living with HIV are more susceptible to neurocognitive impairment. Promoting mental health and physical activity are potential entry points to slow down the progress of neurocognitive impairment among older people living with HIV.

Abstract
HIV-Associated neurocognitive disorder (HAND) is one of the major concerns since it persists in 40% of this population. Nowadays, HAND neuropathogenesis is considered to be caused by the infected cells that cross the brain-blood barrier and produce viral proteins that can be secreted and internalized into neurons leading to disruption of cellular processes. The evidence points to viral proteins such as Tat as the causal agent for neuronal alteration and thus HAND. The hallmarks in Tat-induced neurodegeneration are endoplasmic reticulum stress and mitochondrial dysfunction. Sirtuins (SIRTs) are NAD+-dependent deacetylases involved in mitochondria biogenesis, unfolded protein response, and intrinsic apoptosis pathway. Tat interaction with these deacetylases causes inhibition of SIRT1 and SIRT3. Studies revealed that SIRTs activation promotes neuroprotection in neurodegenerative diseases such Alzheimer's and Parkinson's disease. Therefore, this review focuses on Tat-induced neurotoxicity mechanisms that involve SIRTs as key regulators and their modulation as a therapeutic strategy for tackling HAND and thereby improving the quality of life of people living with HIV.

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.

Aging with HIV in Latin America and the Caribbean: a Systematic Review. Curr HIV/AIDS Rep 2021; 18:1-47.

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
Objectives Although effective antiretroviral therapy (ART) has been used for more than two decades, HIV-associated neurocognitive disorder remains prevalent. Thus, whether ART can improve neurocognitive impairment is controversial. This review aims to explore the effects of ART on cognitive impairment in people living with HIV (PLWH). Methods A systematic literature search was conducted in eight databases (PubMed, Embase, Web of Science, Cochrane Library, CNKI, VIP, China Biology Medicine disc, and WanFang) to identify studies that compare cognitive function between study groups who are administered and not administered ART. We searched for articles published up to April 2019. Article evaluation and data extraction were independently conducted by two reviewers. Results Sixteen articles (6,694 participants)—14 cross-sectional studies and 2 cohort studies—were included in this meta-analysis. The cross-sectional studies demonstrated that ART group did not perform better than the non-ART group (OR = 1.16; 95% CI, 1.03–1.30). However, the cohort studies reported a significant improvement in cognitive function at three months (OR = 4.01; 95% CI, 2.35–6.85) and six months (OR = 9.24; 95% CI, 1.71–49.96) after ART initiation compared with the baseline data. No significant cognitive improvement was found in participants younger than 55 years old, but the two cross-sectional studies showed that ART may improve cognitive function in PLWH under 65 years old with poor physical condition and immune status. Conclusions ART could improve cognitive function in PLWH with poor physical condition and immune status, but it does not considerably improve cognition in the entire PLWH population.

Abstract
OBJECTIVE The authors assessed the association of physical function, social variables, functional status, and psychiatric co-morbidity with cognitive function among older HIV-infected adults. DESIGN From 2012-2014, a cross-sectional study was conducted among HIV-infected patients ages 50 or older who underwent comprehensive clinical geriatric assessment. SETTING Two San Francisco HIV clinics. PARTICIPANTS 359 HIV-infected patients age 50 years or older. MEASUREMENTS Unadjusted and adjusted Poisson regression measured prevalence ratios and 95% confidence intervals for demographic, functional and psychiatric variables and their association with cognitive impairment using a Montreal Cognitive Assessment (MoCA) score < 26 as reflective of cognitive impairment. RESULTS Thirty-four percent of participants had a MoCA score of < 26. In unadjusted analyses, the following variables were significantly associated with an abnormal MoCA score: born female, not identifying as homosexual, non-white race, high school or less educational attainment, annual income < $10,000, tobacco use, slower gait speed, reported problems with balance, and poor social support. In subsequent adjusted analysis, the following variables were significantly associated with an abnormal MoCA score: not identifying as homosexual, non-white race, longer 4-meter walk time, and poor social support. Psychiatric symptoms of depressive, anxiety, and post-traumatic stress disorders did not correlate with abnormal MoCA scores. CONCLUSIONS Cognitive impairment remains common in older HIV-infected patients. Counter to expectations, co-morbid psychiatric symptoms were not associated with cognitive impairment, suggesting that cognitive impairment in this sample may be due to neurocognitive disorders, not due to other psychiatric illness. The other conditions associated with cognitive impairment in this sample may warrant separate clinical and social interventions to optimize patient outcomes.

Abstract
Patients on antiretroviral therapy face new challenges, such as bodily changes. We conducted a cross-sectional study with people living with HIV/AIDS. We investigate the self-perception of body image and its associations. Most of the patients reported negative self-perception of body image (NSPBI), being mostly women, up to 40 years old and with changes in BMI. NSPBI was associated with depressive symptoms and punctual alterations in the redistribution of body fat: face, abdomen and legs, subjects still little elucidated. Assessing neglected aspects can improve the way these patients see themselves, and come to understand the disease as only a part of their lives.

Abstract
OBJECTIVE We explored the prevalence of HIV infection in older rural South Africans and its associations, as well as the point prevalence of dementia and its associations with HIV and aging. DESIGN We utilized a cross-sectional analytic design. METHODS Using the brief Community Screening Instrument for Dementia together with a rapid HIV test, we conducted a home-based screening survey among 1150 older South Africans. We explored the prevalence of HIV and dementia, and their associations using descriptive statistics and logistic regression analysis. RESULTS The HIV prevalence was 4.78%. Overall, participants were on average 71.3 years old, with nearly 70% having no primary school education. HIV+ participants were significantly younger, more likely to be single and had lower BMI. The overall dementia prevalence was 11.04%. HIV+ participants had higher rates of dementia compared with HIV- participants (18.18 vs. 10.68%) but the difference was NS. In adjusted analysis, screened dementia was associated with older age, the presence of self-reported depression and HIV+ status. Participants were also more likely to self-report cognitive impairment if they were older, depressed and had objective evidence of dementia. CONCLUSION Infection with HIV in rural older South Africans is a prevalent problem, and together with older age, is a significant contributor to cognitive impairment. It is possible that HIV infection contributes to dementia on the basis of an acceleration of degeneration - because our HIV-infected participants were younger - AND an accentuation of aging - because of the higher rates of impairment for similar age groups.

Abstract
Coping strategies play a prominent role in maintaining mental health, but little is known about the main coping strategies and potential influential factors among older Chinese adults with HIV/AIDS. Cross-sectional data of 254 older with HIV/AIDS aged 50 ~ 84 years (160 males and 94 females) from Hunan, China were analyzed to evaluate influential factors associated with coping strategies. The scores of all participants in the different sub-scales of confrontation, avoidance and acceptance-resignation were 15.16 ± 4.03, 16.44 ± 2.70, and 11.06 ± 4.00, respectively. For the confrontation coping strategy, higher scores were obtained by those with a higher education level, non-sexually transmitted HIV, and a first diagnosis at less than 50 years old. Avoidance as a coping strategy was significantly associated with a longer period living with the diagnosis. The participants who were females, unemployed, annual income less than 1000 yuan, had lived with HIV for a longer period, and had disclosed their infection status to their family members were more likely to adopt the acceptance-resignation coping strategy in response to HIV/AIDS. These preliminary findings can provide evidence for effective interventions to improve coping capacity and psychological status in this population.

Dopaminergic impact of cART and anti-depressants on HIV neuropathogenesis in older adults. Brain Res 2019; 1723:146398.

Abstract
The success of combination antiretroviral therapy (cART) has transformed HIV infection into a chronic condition, resulting in an increase in the number of older, cART-treated adults living with HIV. This has increased the incidence of age-related, non-AIDS comorbidities in this population. One of the most common comorbidities is depression, which is also associated with cognitive impairment and a number of neuropathologies. In older people living with HIV, treating these overlapping disorders is complex, often creating pill burden or adverse drug-drug interactions that can exacerbate these neurologic disorders. Depression, NeuroHIV and many of the neuropsychiatric therapeutics used to treat them impact the dopaminergic system, suggesting that dopaminergic dysfunction may be a common factor in the development of these disorders. Further, changes in dopamine can influence the development of inflammation and the regulation of immune function, which are also implicated in the progression of NeuroHIV and depression. Little is known about the optimal clinical management of drug-drug interactions between cART drugs and antidepressants, particularly in regard to dopamine in older people living with HIV. This review will discuss those interactions, first examining the etiology of NeuroHIV and depression in older adults, then discussing the interrelated effects of dopamine and inflammation on these disorders, and finally reviewing the activity and interactions of cART drugs and antidepressants on each of these factors. Developing better strategies to manage these comorbidities is critical to the health of the aging, HIV-infected population, as the older population may be particularly vulnerable to drug-drug interactions affecting dopamine.

Abstract
This study was to compare global and domain-specific neurocognitive performance between older people living with HIV (PLWH) taking/not taking efavirenz (EFV) and HIV-negative controls. A cross-sectional study was conducted in Yongzhou city, China. All PLWH older than 50 years listed on the registry of Centres for Disease Control and Prevention were invited to join the study. Frequency matching was used to sample HIV-negative controls according to the distribution of age, sex, and years of formal education of older PLWH. A total of 308 older PLWH and 350 HIV-negative controls completed the face-to-face interview and neurocognitive assessment using the comprehensive neuropsychological test battery. After adjusting for significant confounders, older PLWH taking EFV showed poorer performance in memory (p = 0.020), verbal fluency (p = 0.002), and poorer global neurocognitive performance (p = 0.032) than those without EFV use. Compared to HIV-negative controls, older PLWH taking EFV had poorer performance in all neurocognitive domains (p values: <0.001-0.003) and poorer global neurocognitive performance (p < 0.001). Similar trends were observed when comparing older PLWH without using EFV versus HIV-negative controls, with the exception of verbal fluency (p = 0.560). Health care workers should monitor the neuropsychological performance of older PLWH, epically those who were taking EFV. Longitudinal studies are warranted.

Abstract
HIV-associated neurocognitive disorders (HAND) remain frequent even among individuals receiving combined antiretroviral therapy (cART). In addition, HAND may adversely affect the quality of life and adherence to cART. There is scarce epidemiological information about HAND in Latin America. This cross-sectional study recruited HIV-infected patients from a tertiary teaching institution in São Paulo, Brazil, between May 2013 and February 2015. The patients were adults with at least 4 years of education and patients with current neurological or psychiatric diseases were excluded. HAND remain frequent even among individuals receiving cART, use of psychoactive substance, or inability to understand the content for neuropsychological evaluation. We used standardized tools to evaluate depression, use of psychoactive substances, and daily life activities, and we performed a comprehensive neuropsychological examination. HAND was classified using the Frascati criteria. Prevalence of HAND was estimated, and an associated variable of symptomatic HAND was identified by logistic regression. Four-hundred twelve HIV-infected patients were included [male: 281 (68%), mean age of 45.3 years]. Most of them [n = 340 (83.7%)] had an undetectable viral load. The prevalence of HAND was 73.6% (n = 303): 210 (50.9%) had asymptomatic neurocognitive involvement (ANI), 67 (16.2%) had mild neurocognitive disorder (MND), and 26 (6.3%) had HIV-associated dementia (HAD). The univariate logistic regression analysis showed that female gender, age older than 50 years, <11 years of schooling, CD4 count below 200 cells/mm3, presence of previous illnesses (e.g., diabetes, hypertension), opportunistic disease history, and a Beck Depression Inventory (BDI) score between 13 and 19 points were factors associated with symptomatic HAND (MND and HAD). However, a BDI score between 13 and 19 points was the single independent variable associated with symptomatic HAND. HAND was highly prevalent in São Paulo, Brazil, and ANI was the more frequent category of HAND. However, 22.5% of participants had symptomatic HAND. This finding constitutes a challenge in clinical practice. A BDI score between 13 and 19 points was the single independent variable associated with symptomatic HAND.

Abstract
INTRODUCTION Combined antiretroviral therapy has enabled human immunodeficiency virus (HIV) carriers to live longer. This increased life expectancy is associated with the occurrence of degenerative diseases, including HIV-associated neurocognitive disorders (HAND), which are diagnosed via a complex neuropsychological assessment. The International HIV Dementia Scale (IHDS) is a screening instrument validated in Brazil for use in the absence of neuropsychological evaluation. HIV patients are frequently diagnosed with depression. We aimed to determine the prevalence of neurocognitive impairment using the IHDS and depressive disorders using the Hamilton Rating Scale for Depression (HAM-D17), compare the IHDS performance with the performances on the Timed Gait Test (TGT), the Digit Symbol Coding Test (DS) and the Brazilian version of the Scale of Instrumental Activities of Daily Living (IADL), and evaluate the association between the IHDS performance and clinical-demographic variables. METHODS One hundred fourteen patients were evaluated in a cross-sectional study conducted in a public outpatient clinic for infectious diseases in Marília City, State of São Paulo, Brazil. Data were collected following consultation. Statistical analysis was performed in accordance with the nature and distribution of the data and hypotheses. RESULTS According to the IHDS, 53.2% of the sampled patients were neuropsychologically impaired. According to the HAM-D17, 26.3% had depressive disorders. There were significant associations between the IHDS and the TGT and DS. Multiple regression analysis indicated that female gender, educational level, and cluster of differentiation 4 (CD4) levels were significantly and independently associated with neurocognitive impairment. CONCLUSIONS The prevalence of neurocognitive impairment according to the IHDS is high and associated with female gender, education level, and low CD4 levels.

Abstract
BACKGROUND Little is known about the prevalence and burden of HIV associated neurocognitive disorder (HAND) among patients on combination antiretroviral therapy (cART) in sub-Saharan Africa. We estimated the prevalence of HAND in adult Malawians on cART and investigated the relationship between HAND and adherence to cART. METHODS HIV positive adults in Blantyre, Malawi underwent a full medical history, neurocognitive test battery, depression score, Karnofsky Performance Score and adherence assessment. The Frascati criteria were used to diagnose HAND and the Global Deficit Score (GDS) was also assessed. Blood was drawn for CD4 count and plasma nevirapine and efavirenz concentrations. HIV negative adults were recruited from the HIV testing clinic to provide normative scores for the neurocognitive battery. RESULTS One hundred and six HIV positive patients, with median (range) age 39 (18-71) years, 73% female and median (range) CD4 count 323.5 (68-1039) cells/µl were studied. Symptomatic neurocognitive impairment was present in 15% (12% mild neurocognitive disorder [MND], 3% HIV associated dementia [HAD]). A further 55% fulfilled Frascati criteria for asymptomatic neurocognitive impairment (ANI); however factors other than neurocognitive impairment could have confounded this estimate. Neither the symptomatic (MND and HAD) nor asymptomatic (ANI) forms of HAND were associated with subtherapeutic nevirapine/efavirenz concentrations, adjusted odds ratio 1.44 (CI. 0.234, 8.798; p = 0.696) and aOR 0.577 (CI. 0.09, 3.605; p = 0.556) respectively. All patients with subtherapeutic nevirapine/efavirenz levels had a GDS of less than 0.6, consistent with normal neurocognition. DISCUSSION/CONCLUSION Fifteen percent of adult Malawians on cART had a diagnosis of MND or HAD. Subtherapeutic drug concentrations were found exclusively in patients with normal neurocognitive function suggesting HAND did not affect cART adherence. Further study of HAND requires more robust locally derived normative neurocognitive values and determination of the clinical relevance of ANI.

Abstract
The vast majority of people living with human immunodeficiency virus (HIV) infection reside in resource-limited settings. As compared with resource-rich settings, there are important differences in the epidemiology and outcomes of HIV infection in resource-limited settings. Nonetheless, little HIV neurology research occurs in these regions. We will first review clinical, epidemiological, and translational HIV neurology research originating from resource-limited settings. We will then discuss the barriers to conducting neurologic research, such as limited human resources, diagnostics, and access to medications. Finally, we will review existing initiatives to build capacity for research in resource-limited settings. Despite the barriers, there is growing interest in and opportunities for collaborative international neurologic research. Including diverse viral and human populations from across the globe in research opens possibilities for important implementation science, clinically oriented science, and basic science discoveries.

Abstract
OBJECTIVES HIV-associated neurocognitive disorder (HAND) is an independent predictor of early mortality and is associated with many difficulties in activities of daily living. We sought to determine the prevalence of and risk factors for HAND in HIV-infected Koreans. In addition, we investigated the performance of screening tools and components of neuropsychological (NP) tests for diagnosing HAND. METHODS HIV-infected patients were enrolled consecutively from two different urban teaching hospitals in Seoul, South Korea between March 2012 and September 2012. Participants completed a detailed NP assessment of six cognitive domains commonly affected by HIV. The Frascati criteria were used for diagnosing HAND. Four key questions, the International HIV Dementia Scale (IHDS) and Montreal Cognitive Assessment (MoCA)-K were also assessed as potential tools for screening for HAND. RESULTS Among the 194 participants, the prevalence of HAND was 26.3%. Asymptomatic neurocognitive impairment and minor neurocognitive disorder accounted for 52.9 and 47.1% of the patients with HAND, respectively. In multivariate analysis, haemoglobin (Hb) level ≤ 13 g/dL (P = 0.046) and current use of a protease inhibitor-based regimen (P = 0.031) were independent risk factors for HAND. The sensitivity and specificity of the IHDS were 72.6 and 60.8%, and those of MoCA-K were 52.9 and 73.4%, respectively. The IHDS (P < 0.001) and MoCA-K (P < 0.001) were both useful for screening for HAND. Among NP tests, the sensitivity and specificity of the Grooved Pegboard Test were 90.2 and 72.0%, and those of the Wisconsin Card Sorting Test were 61.2 and 84.4%, respectively. CONCLUSIONS HAND is a prevalent comorbidity in HIV-infected Koreans. Active screening and diagnosis with effective tools, such as the IHDS, MoCA-K and Grooved Pegboard Test, could be used to identify this important complication.

Abstract
In the era of greatly improved pharmacological treatment of HIV infection through highly active antiretroviral therapy (HAART), HIV patients experience reduced viral loads, reduced opportunistic infections, increased CD4+ T cell count, and greater life expectancy. Although life expectancy is increased, patients often develop neurological disturbances that may persist for long periods, seriously jeopardizing quality of life and adherence to the medication protocols of HAART. For these reasons, HIV-associated neurological disorders have gained importance in both clinical and basic investigations of HIV infection. Depression is the most prevalent neuropsychiatric disorder among people living with HIV. In this review, we discuss how HIV can predispose infected individuals to depression by several interrelated mechanisms. These include inducing chronic elevation of cytokines through activation of microglia and astrocytes; decreasing monoaminergic function; inducing neurotoxicity, especially in dopaminergic neurons; and reducing brain-derived neurotrophic factor. These viral pathways interact with psychosocial factors to create the depressive state. HIV depression has a great impact on quality of life and implementation of antiretroviral therapy, and thus, recognition of these modes of action is significant for understanding HIV neuropathology and for selecting modalities for pharmacologic treatment.

Abstract
Although HIV-associated dementia (HAD) occurs in less than 5 % of individuals with access to combination antiretroviral therapy, rates of milder forms of HIV-associated neurocognitive disorder (HAND) are much higher. We sought to define an optimal cut point for the International HIV Dementia Scale (IHDS) in Thailand for the identification of symptomatic HAND, defined as both HAD and mild neurocognitive disorder. We then sought to determine if adding a simple test from a larger neuropsychological battery could improve the performance characteristics for identifying symptomatic HAND. In this study, subjects comprising 75 seropositive adults in Bangkok, Thailand, completed neuropsychological tests and underwent a full neurological assessment. HAND diagnoses were determined by consensus conference using the 2007 Frascati criteria, blinded to the IHDS results. The optimal IHDS cut point was determined by receiver operating characteristic analysis with cross-validation. Individual neuropsychological tests were then evaluated and combined with the IHDS to test performance characteristics. The IHDS was poor at detecting symptomatic HAND at the optimized cut point of ≤ 10 (sensitivity, 53.3 %; specificity, 89.8 %). Trail Making Test A was most effective in improving performance characteristics when combined with the IHDS, with net sensitivity of 86 % and specificity of 79 %. In this setting, the IHDS performed poorly in identifying symptomatic HAND, but was substantially improved by the addition of Trail Making Test A, which typically requires less than 2 min to complete. This combination should be validated in a larger setting since it may address the critical need for HAND screening instruments in international settings.
