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.

Changes in Cerebrospinal Fluid, Liver and Intima-media-thickness Biomarkers in Patients with HIV-associated Neurocognitive Disorders Randomized to a Less Neurotoxic Treatment Regimen. J Neuroimmune Pharmacol 2023; 18:551-562.

Abstract
The prevalence of neurocognitive impairment in people living with HIV is estimated between 30 and 50%. The pathogenesis of HIV-associated neurocognitive disorders is complex and multifactorial. Aim of the study was to measure the change in CSF biomarkers, Fibroscan and IMT measurements in PLWH with HAND randomized to a less neurotoxic regimen, or continuing their treatment. Adult patients with HAND were screened and enrolled if presenting no major resistance associated mutations, no HIV viral replication, not on efavirenz or darunavir, with R5-tropic HIV and without major confounding conditions. Lumbar puncture, IMT and Fibroscan measurements were performed. After 1:1 randomization to a less neurotoxic regimen consisting of darunavir/cobicistat plus emtricitabine plus maraviroc, or mantaining actual care, tests were repeated after 24 weeks: CSF biomarkes (HIV RNA, tau, p-tau, Beta-amyloid1-42, S100Beta and neopterin) were included. Non-parametric tests (Mann-Whitney and Wilcoxon's) were used. 28 participants completed the study. Male and European ancestry were prevalent; median age was 55 years (51-60). All patients were virally suppressed; median CD4 + count was 626 cell/uL (469-772). Baseline characteristics were similar between the study arms. A significant decrease in CSF p-tau and an increase in CSF neopterin and NFL were observed. We observed a significant reduction in liver stiffness at W24. Despite a small sample size we observed changes in neuromarkers and in hepatic stiffness in patients randomized to the experimental arm. We observed changes in CSF biomarkers (lower phosphorylated-tau and higher neopterin and NFL) that need to be replicated in large cohorts. Subclinical neurotoxicity may be observed in patients with HAND and warrants prospective studies.

Abstract
This paper reports the proceedings of a virtual meeting convened by the European Interdisciplinary Council on Ageing (EICA), to discuss the involvement of infectious disorders in the pathogenesis of dementia and neurological disorders leading to dementia. We recap how our view of the infectious etiology of dementia has changed over the last 30 years in light of emerging evidence, and we present evidence in support of the implication of infection in dementia, notably Alzheimer's disease (AD). The bacteria and viruses thought to be responsible for neuroinflammation and neurological damage are reviewed. We then review the genetic basis for neuroinflammation and dementia, highlighting the genes that are currently the focus of investigation as potential targets for therapy. Next, we describe the antimicrobial hypothesis of dementia, notably the intriguing possibility that amyloid beta may itself possess antimicrobial properties. We further describe the clinical relevance of the gut-brain axis in dementia, the mechanisms by which infection can move from the intestine to the brain, and recent findings regarding dysbiosis patterns in patients with AD. We review the involvement of specific pathogens in neurological disorders, i.e. SARS-CoV-2, human immunodeficiency virus (HIV), herpes simplex virus type 1 (HSV1), and influenza. Finally, we look at the role of vaccination to prevent dementia. In conclusion, there is a large body of evidence supporting the involvement of various infectious pathogens in the pathogenesis of dementia, but large-scale studies with long-term follow-up are needed to elucidate the role that infection may play, especially before subclinical or clinical disease is present.

Abstract
In this fifth decade of the human immunodeficiency virus (HIV) epidemic, central nervous system (CNS) complications including cognitive impairment and mental health remain a burden for people with HIV (PWH) on antiretroviral therapy. Despite the persistence of these complications, which often co-occur, the underlying pathophysiology remains elusive and consequently treatments remain limited. To continue to grow our understanding of the underlying mechanisms of CNS complications among PWH, there is a need to reexamine our current approaches, which are now more than 2 decades old. At the 2021 National Institutes of Health-sponsored meeting on Biotypes of CNS Complications in PWH, the Neurobehavioral Working Group addressed the following: (1) challenges inherent to determining CNS complications; (2) heterogeneity in CNS complications; and (3) problems and solutions for examining integrated biotypes. The review below provides a summary of the main points presented and discussed by the Neurobehavioral Working Group at the meeting.

Cognitive performance in a South African cohort of people with HIV and comorbid major depressive disorder. J Neurovirol 2022; 28:537-551.

Abstract
Cognitive performance in people with HIV (PWH) may be affected by brain injury attributable to the infection itself, by other medical and psychiatric comorbidities (including major depressive disorder; MDD), and by psychosocial factors (e.g., education, food insecurity). We investigated effects of these variables on cognitive performance in a South African cohort of PWH with comorbid MDD and incomplete adherence to antiretroviral therapy (ART). We also examined (a) associations of depression severity with cognitive performance, and (b) whether improvement in depression led to improved cognitive performance. Participants (N = 105) completed baseline neuropsychological, psychiatric, and sociodemographic assessments. Subsequently, 33 were assigned to a cognitive-behavioural therapy for ART adherence and depression (CBT-AD) and 72 to standard-of-care treatment. Eight months post-baseline, 81 (nCBT-AD = 29) repeated the assessments. We investigated (a) baseline associations between sociodemographic, medical, and psychiatric variables and cognitive performance, (b) whether, from baseline to follow-up, depression and cognitive performance improved significantly more in CBT-AD participants, and (c) associations between post-intervention improvements in depression and cognitive performance. At baseline, less education (β = 0.62) and greater food insecurity (β = -0.20) predicted poorer overall cognitive performance; more severe depression predicted impairment in the attention/working memory domain only (β = -0.25). From baseline to follow-up, depression decreased significantly more in CBT-AD participants (p = .017). Improvement over time in depression and cognitive performance was not significantly associated except in the attention/working memory domain (p = .026). Overall, factors associated with cognitive performance were unrelated to brain injury. We conclude that clinicians examining PWH presenting with cognitive difficulties must assess depression, and that researchers investigating cognitive impairment in PWH must collect information on psychosocial factors.

J Family Med Prim Care 2022; 11:5060-5064. [PMID: 36505608 PMCID: PMC9731045 DOI: 10.4103/jfmpc.jfmpc_356_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2021] [Revised: 07/05/2021] [Accepted: 07/12/2021] [Indexed: 12/15/2022] Open
Abstract
Introduction Human immunodeficiency virus (HIV)-associated neurocognitive disorders (HAND) comprise impairment of multiple cognitive domains and cause significant morbidity. International HIV Dementia Scale (IHDS) is a quite sensitive and specific method for screening for HAND, and Modified Mini-Mental State Examination (3MS), though nonspecific, contains more parameters for screening for neurocognition. Hence, we compared 3MS and IHDS as screening tools for HAND with an aim to find out which was a better screening tool for HAND. Methods Using 3MS and IHDS, we assessed the cognitive status of 200 HIV-positive patients (65% males) and 84 controls, presenting to the Department of Medicine, King George's Medical University, Lucknow, India from September 2015 to September 2019. Results According to 3MS, 42 (21%) HIV-positive patients were neurocognitively impaired (mean 76.24 ± 1.51), and 158 (79%) patients were not (mean 87.02 ± 4.16). As per IHDS, 185 (92.5%) HIV patients were neurocognitively impaired (mean 8.45 ± 0.88), and 15 (7.5%) patients were not (mean 11.13 ± 0.35). The mean 3MS score of controls was 87.56 ± 4.26, and the IHDS score was 9.73 ± 1.00. According to Patient Health Questionnaire-9 (PHQ-9), moderate depression occurred in only 3.5% of the patients, and the rest had only minimal or mild depression. In IHDS, psychomotor speed was the most affected parameter, whereas in 3MS, similarities were the most affected. Conclusion IHDS may be over diagnosing neurocognitive impairment in HIV patients due to difficulty in understanding the test, especially psychomotor speed testing. 3MS may be more accurate for detecting neurocognitive impairment in HIV patients, and scale combining both these methods may be a still better choice.

Abstract
BACKGROUND HIV-associated neurocognitive disorders (HAND) have been suggested as persistent even with effective antiretroviral therapy (ART). Aims were to evaluate HAND prevalence and associated factors, in a large cohort of people-with-HIV (PWH). METHODS ART-treated PWH, underwent a neuropsychological examination through a battery of 12 tests exploring 5 different domains, between 2009 and 2020, were included in this cross-sectional analysis. HAND were classified according to Frascati's criteria. Participants were defined as complaining or not-complaining if a cognitive complaint was reported or not. Chi-square for trend and multivariable logistic regression were fitted. RESULTS Overall, 1424 PWH were enrolled during four three-years periods. HAND prevalence was 24%; among complainers (572/1424), it was 38%, higher than among not-complainers (15%). Over the study period, a decreasing HAND prevalence was found in the entire population (P < 0.001) and in complaining (P < 0.001); in not-complaining it remained stable (P = 0.182). Factors associated with HAND were older age, lower educational level, lower current CD4+ T-cell count and HCV co-infection. Compared to nonnucleoside reverse transcriptase inhibitors, receiving dual and integrase strand transfer inhibitor (INSTI)-based therapies was associated with a decreased risk of HAND, as well as being tested in more recent years. CONCLUSIONS In this large cohort of ART-treated PWH, mostly virologically suppressed, a remarkable decreasing HAND prevalence was observed. Besides HIV- and patient-related factors, the reduced risk of HAND found with dual and INSTI-based regimens along with a more recent ART initiation, could suggest a potential role of new treatment strategies in this decline, due to their greater virologic efficacy and better tolerability.

Correlations between cerebrospinal fluid biomarkers, neurocognitive tests, and resting-state electroencephalography (rsEEG) in patients with HIV-associated neurocognitive disorders. J Neurovirol 2022; 28:226-235. [PMID: 35044644 DOI: 10.1007/s13365-021-01047-y] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2021] [Revised: 11/05/2021] [Accepted: 12/18/2021] [Indexed: 12/01/2022]
Abstract
HIV-associated neurocognitive disorders (HAND) are highly prevalent in people living with HIV (PLWH) despite successful treatment with combination antiretroviral therapy (cART). HAND pathogenesis is complex and definitive surrogate biomarkers are not clearly defined. Brain function has been assessed through the evaluation of cortical source rhythms with delta waves associated with neurological impairment. The aim of this study was to assess the correlation between EEG cortical sources, cerebrospinal fluid (CSF) biomarkers, and neurocognitive tests in PLWH with HAND. PLWH with HAND without significant comorbidities were enrolled. Baseline rsEEG-LORETA waves, CSF biomarkers (t-tau, p-tau, β-amiloid42, neopterin, S100β), and neurocognitive tests were correlated and compared through non-parametric tests (Spearman's rho and Mann-Whitney); data are presented as medians (interquartile ranges). Fifty-four patients were enrolled. Median time of suppressed HIV-RNA and CD4+ T-lymphocyte were 10 years (5.5-15) and 691/uL (477-929). Thirty-nine participants (72%) underwent CSF collection: abnormal biomarkers were found in a small percentage. Only neopterin showed a statistically significant correlation with delta activity [parietal (rho 0.579; p < 0.001), occipital (rho 0.493; p = 0.007), and global sources (rho 0.464 p = 0.011)]. Seven patients (12.9%) showed an abnormal neopterin level (> 1.5 ng/mL) with significantly higher delta source activity compared to the ones with in-range concentrations. We observed a statistically significant correlation between working memory test Trail Making B with both CSF neopterin levels and delta waves (p values < 0.05). In a small sample of PLWH with HAND, we observed that higher CSF neopterin levels were associated with higher EEG delta waves and worse working memory tests.

Abstract
The convergence of the HIV and SARS-CoV-2 pandemics is an emerging field of interest. In this review, we outline the central nervous system (CNS) effects of COVID-19 in the general population and how these effects may manifest in people with HIV (PWH). We discuss the hypothetical mechanisms through which SARS-CoV-2 could impact the CNS during both the acute and recovery phases of infection and the potential selective vulnerability of PWH to these effects as a result of epidemiologic, clinical, and biologic factors. Finally, we define key research questions and considerations for the investigation of CNS sequelae of COVID-19 in PWH.

Abstract
PURPOSE OF REVIEW Involvement of the central nervous system (CNS) in HIV-1 infection is commonly associated with neurological disorders and cognitive impairment, commonly referred to as HIV-associated neurocognitive disorders (HAND). Severe and progressive neurocognitive impairment is rarely observed in the post-cART era; however, asymptomatic and mild neurocognitive disorders still exist, despite viral suppression. Additionally, comorbid conditions can also contribute to the pathogenesis of HAND. RECENT FINDINGS In this review, we summarize the characterization of HAND, factors contributing, and the functional impairments in both preclinical and clinical models. Specifically, we also discuss recent advances in the animal models of HAND and in in vitro cultures and the potential role of drugs of abuse in this model system of HAND. Potential peripheral biomarkers associated with HAND are also discussed. Overall, this review identifies some of the recent advances in the field of HAND in cell culture studies, animal models, clinical findings, and the limitations of each model system, which can play a key role in developing novel therapeutics in the field.

Abstract
Human Immunodeficiency Virus type 1 (HIV-1) infection is a chronic disease that affects ~40 million people worldwide. HIV-associated neurocognitive disorders (HAND) are common in individuals with HIV-1 Infection, and represent a recent public health problem. Here we evaluate the performance of a recently proposed short protocol for detecting HAND by studying 60 individuals with HIV-1-Infection and 60 seronegative controls from a Caribbean community in Barranquilla, Colombia. The short evaluation protocol used significant neuropsychological tests from a previous study of asymptomatic HIV-1 infected patients and a group of seronegative controls. Brief screening instruments, i.e., the Mini-mental State Examination (MMSE) and the International HIV Dementia Scale (IHDS), were also applied. Using machine-learning techniques, we derived predictive models of HAND status, and evaluated their performance with the ROC curves. The proposed short protocol performs exceptionally well yielding sensitivity, specificity, and overall prediction values >90%, and better predictive capacity than that of the MMSE and IHDS. Community-specific cut-off values for HAND diagnosis, based on the MMSE and IHDS, make this protocol suitable for HAND screening in individuals from this Caribbean community. This study shows the effectivity of a recently proposed short protocol to detect HAND in individuals with asymptomatic HIV-1-Infection. The application of community-specific cut-off values for HAND diagnosis in the clinical setting may improve HAND screening accuracy and facilitate patients' treatment and follow-up. Further studies are needed to assess the performance of this protocol in other Latin American populations.

Abstract
Neurological manifestations in pandemics frequently cause short and long-term consequences which are frequently overlooked. Despite advances in the treatment of infectious diseases, nervous system involvement remains a challenge, with limited treatments often available. The under-recognition of neurological manifestations may lead to an increase in the burden of acute disease as well as secondary complications with long-term consequences. Nervous system infection or dysfunction during pandemics is common and its enduring consequences, especially among vulnerable populations, are frequently forgotten. An improved understanding the possible mechanisms of neurological damage during epidemics, and increased recognition of the possible manifestations is fundamental to bring insights when dealing with future outbreaks. To reverse this gap in knowledge, we reviewed all the pandemics, large and important epidemics of human history in which neurological manifestations are evident, and described the possible physiological processes that leads to the adverse sequelae caused or triggered by those pathogens.

Abstract
BACKGROUND Depression and neurocognitive impairment are highly prevalent among persons living with HIV and associated with poorer clinical outcomes; however, longitudinal studies of depression-neurocognition relationships in youth living with HIV (YLWH), and the role of antiretroviral therapy (ART), are lacking. This study tested whether (1) depressive symptomatology, across somatic, cognitive, and affective symptom domains, improved with ART and (2) more severe depressive symptoms at baseline were associated with poorer neurocognitive function and poorer HIV suppression. SETTING Data were collected from 181 YLWH (18-24 years) who were treatment-naive, a subset of whom (n = 116) initiated ART. METHODS Participants were categorized into elevated (DS) or nonelevated (non-DS) depressive symptom groups at entry (Beck Depression Inventory-II ≥14) and followed for 36 months. Neurocognition (5-domain battery) and depressive symptoms were repeatedly assessed. Longitudinal models examined depressive symptomatology, neurocognition, and odds of HIV nonsuppression by group. RESULTS Greater improvements in depressive symptoms were observed in the DS group over 36 months [beta = -0.14, (-0.24 to -0.03)], particularly within cognitive and affective domains. Verbal learning performance increased in the DS group [beta = 0.13, (0.01 to 0.24)], whereas psychomotor function improved somewhat in the non-DS group [beta = -0.10, (-0.22 to 0.00)]. Adjusted for ART adherence, odds of HIV nonsuppression did not significantly differ by group [odds ratio = 0.22, (0.04 to 1.23)]; however, greater somatic symptoms at study entry were associated with an increased risk of nonsuppression over time [odds ratio = 2.33 (1.07 to 5.68)]. CONCLUSION Depressive symptoms were associated with differential neurocognitive trajectories, and somatic depressive symptoms at baseline may predict poorer subsequent HIV suppression. Identifying and treating depressive symptoms at ART initiation may benefit neurocognitive and clinical outcomes in YLWH.

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
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
Highly active antiretroviral treatment has led to unprecedented efficacy and tolerability in people living with HIV. This effect was also observed in the central nervous system with the nowadays uncommon observation of dementias; yet in more recent works milder forms are still reported in 20-30% of optimally treated individuals. The idea of a subclinical neuronal toxicity induced by antiretrovirals has been proposed and was somehow supported by the late-emerging effects associated with efavirenz use. In this manuscript we are reviewing all the potential mechanisms by which antiretroviral drugs have been associated with in vitro, ex vivo, or in vivo toxicity to cells pertaining to the central nervous system (neurons, astrocytes, oligodendrocytes, and endothelial cells). These include direct or indirect effects and pathological pathways such as amyloid deposition, damage to small cerebral vessels, and impairment in neurotransmission. The aim of this review is therefore to provide a detailed description of the available literature in order to guide further clinical research for improving patients' neurocognition and quality of life.

Abstract
The aims of the present study were to evaluate the prevalence of undiagnosed mental health conditions (UMHC) in people living with HIV (PLWHIV) on antiretroviral treatment and with long-term suppressed HIV viremia, and its association with neurocognitive impairment (NCI). A cross-sectional observational study on HIV subjects, ≥18 years old, on stable antiretroviral treatment and with HIV viral load <50 copies/mL was carried out. Patients with known comorbidities, substances abuse, anxiety or depression were excluded. UMHC were evaluated by the Millon Clinical Multiaxial Inventory-III and NCI by Frascati criteria. The association between NCI and sociodemographic, clinical HIV variables and mental health conditions was analyzed. Further, the relationship between mental health conditions scores and NCI diagnosis was evaluated. Eighty patients were included, 37.5% had at least one undiagnosed mental health condition, and 26.3% had NCI. The most frequent mental health conditions were: anxiety (21.3%); bipolar disorder (11.3%); and substance dependence (8.8%). Only longer time since HIV diagnosis (p = 0.030) and at least one mental health condition diagnosis (p = 0.002) showed an association with NCI. Participants with NCI presented higher scores in anxiety, alcohol dependence and post-traumatic stress. Undiagnosed mental health conditions are frequent in PLWHIV. These disorders cannot be identified by HIV clinicians or basic screening questionnaires, and they are not usually self-reported by patients. UMHC could act as confounders in the evaluation of NCI.

Abstract
BACKGROUND Protease inhibitor monotherapy (PIM) for human immunodeficiency virus (HIV) may exert suboptimal viral control in the central nervous system. We determined whether cerebral blood flow (CBF) and regional brain volumes were associated with PIM, and whether specific cognitive domains were associated with imaging biomarkers. METHODS Cognitive assessments and brain magnetic resonance imaging were performed after the final visit of a randomized HIV-treatment strategy trial. Participants were virologically suppressed on triple therapy at trial entry and followed for 3-5 years. We studied 37 patients randomized to ongoing triple therapy and 39 randomized to PIM. Resting CBF and normalized volumes were calculated for brain regions of interest, and correlated with treatment strategy and neuropsychological performance. RESULTS Mean age was 48.1 years (standard deviation 8.6 years), 63 male (83%), and 64 white (84%). Participants had median 8.1 years (interquartile range 6.4, 10.8) of antiretroviral therapy experience and CD4+ counts of median 640 cells/mm3 (interquartile range 490, 780). We found no difference between treatment arms in CBF or regional volumes. Regardless of treatment arm, poorer fine motor performance correlated with lower CBF in the caudate nucleus (P = .01), thalamus (P = .04), frontal cortex (P = .01), occipital cortex (P = .004), and cingulate cortex (P = .02), and was associated with smaller supratentorial white matter volume (decrease of 0.16 in Z-score per -1% of intracranial volume, 95% confidence interval 0.02-0.29; P = .023). CONCLUSIONS PIM does not confer an additional risk of neurological injury compared with triple therapy. There were correlations between fine motor impairment, grey matter hypoperfusion, and white matter volume loss. CLINICAL TRIALS REGISTRATION ISRCTN-04857074.

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 Low vitamin D levels are associated with higher odds of cognitive dysfunction in the older population, and in subjects with mental disorders or with chronic neurologic diseases. With combination antiretroviral therapy (cART), incidence of HIV-associated dementia has reduced, while the prevalence of milder forms of neurocognitive impairment (NCI) persisted stable over time. Hypovitaminosis D is often found in HIV infection but its association with NCI has not been investigated yet. The aim was to explore this association in a clinic-based HIV-positive population. METHODS A retrospective, cross-sectional analysis of an existing monocenter dataset obtained from patients undergoing neuropsychological assessment in routine clinical care between January, 2011 and December, 2016 was carried out. NCI was assessed through a standardized battery of 13 tests on 5 different cognitive domains and HIV-associated neurocognitive deficit (HAND) was classified according to Frascati's criteria. Vitamin D deficiency was defined by 25 hydroxy-vitamin D 25(OH)D levels < 10 ng/mL. Logistic regression was adjusted for main associated covariates and seasonality. RESULTS 542 patients were included: 96.7% were receiving cART, median CD4 count was 611/mmc (IQR, 421-809), HIV RNA was < 40 cp/mL in 85.8%. Median 25(OH)D was 23.2 ng/mL (IQR, 15.6-29.2), with vitamin D insufficiency 67.7% and deficiency in 9.4%. Overall, NCI was found in 37.1% and HAND in 22.7%. Compared to patients with higher vitamin D levels, subjects with vitamin D deficiency had increased proportions of NCI (52.9% versus 35.4%; p = 0.014) or of HAND (42.9% versus 24.9%; p = 0.012). Median NPZ-8 scores were significantly different based on vitamin D levels (p = 0.021). At multivariable analyses, vitamin D deficiency was the only risk factor of NCI (OR 2.05; 95% CI 1.04-4.05; p = 0.038) or of HAND (OR 2.12; 95% CI 0.99-4.54; p = 0.052). CONCLUSIONS In HIV-positive persons, severe hypovitaminosis D was independently associated with a higher risk of neurocognitive impairment in general, and of HIV-associated neurocognitive disorders in particular. Future studies are needed to elucidate causal relationship and whether vitamin D supplementation may reverse this risk.

Abstract
PURPOSE OF REVIEW Neurocognitive disorders are not uncommon in HIV-positive patients but their pathogenesis is multifactorial and incompletely understood. After excluding contributing comorbidities, several factors may impair neurocognition including severe immune suppression, incomplete antiviral efficacy, drugs' persistent immune activation, vascular abnormalities, and drugs' neurotoxicity. The effectiveness of targeted antiretroviral strategies on these risk factors is unknown. RECENT FINDINGS Recent studies support the idea that residual cerebrospinal fluid HIV RNA in the setting of plasma viral suppression is associated with compartmental immune activation but the link to neuronal damage is debated. Some authors have reported an incomplete antiviral efficacy in macrophage-derived cells but targeted antiretroviral regimen switches have not been performed. Additionally, improvements in neurocognition using drugs with better central nervous system penetration or maraviroc (associated with favorable immunological properties) have been observed in pilot studies. Trials evaluating specific interventions for cardiovascular health (including brain white matter abnormalities) and neurotoxicity of antiretrovirals are warranted. Central nervous system-targeted antiretroviral strategies are needed in patients with uncontrolled cerebrospinal HIV replication, and they may be suggested in subjects with low CD4 nadir, individuals carrying drug-resistant viruses, and those with compartmental immune activation.

Abstract
OBJECTIVE HIV infection chronically affects the central nervous system (CNS). Olfactory mucosa is a unique site in the respiratory tract that is directly connected to the CNS; thus we wanted to evaluate olfactory mucosa as a surrogate of CNS sampling. DESIGN We conducted a preliminary study examining HIV populations and susceptible cells in the olfactory mucosa. METHODS Olfactory mucosa was sampled by minimally invasive brushing. Cerebrospinal fluid (CSF) analyses were performed as per routine clinical procedures. Olfactory marker protein, CD4+, CD8+, and trans-activator of transcription (TAT) expressions were assessed by immunohistochemistry. Plasma, CSF, and olfactory mucosa HIV-RNA were quantified using the Cobas AmpliPrep/Cobas TaqMan assay, whereas HIV proviral DNA was evaluated on peripheral blood mononuclear cell and olfactory mucosa. HIV-1 env deep sequencing was performed for phylogenetic analysis. RESULTS Among ART-naive participants, 88.2% (15/17), and among ART-treated participants, 21.4% (6/28) had detectable HIV-RNA in samples from their olfactory mucosa; CSF escape was more common in patients with olfactory mucosa escape (50 vs. 7.9%; P = 0.010). Olfactory mucosa samples contained few cells positive for CD4, CD8, or HIV-DNA, and no HIV TAT-positive cells, indicating that this approach efficiently samples virions in the olfactory mucosa, but not HIV-infected cells. Yet, using a deep sequencing approach to phylogenetically compare partial HIV env genes in five untreated participants, we identified distinct viral lineages in the OM. CONCLUSIONS The results of this study suggest that nasal brushing is a well tolerated and useful technique for sampling the olfactory mucosa. HIV-RNA was detected in most naïve and in some treated patients, warranting larger longitudinal studies.

Abstract
HIV-infected (HIV+) women may be more vulnerable to neurocognitive impairment (NCI) due to psychological and physiological factors but previous studies show mixed findings. We investigated the neurocognitive performances in HIV+ versus HIV- women and men. This cross-sectional analysis included 669 HIV+ patients (223 women) and 1338 HIV-uninfected (HIV-) controls (446 women) which were frequency matched on sex, education, and 5-year age categories. NCI was screened using the Mini-mental State Examination. Psychomotor speed was assessed using timed alternating hand sequence test. Prevalence of NCI was higher among women versus men in the HIV+ group (16.1% vs 10.5%) but not the HIV- group (4.3% vs 3.5%). HIV+ women performed worse compared to men on psychomotor speed, orientation, attention, and calculation, whereas HIV- women performed worse compared to men on attention and calculation. Adjusted interaction effects of HIV status × sex (women vs men) were significant on orientation, attention, and calculation, and marginally significant on psychomotor speed (p = 0.053). In multivariable models, among both HIV+ women and men, less years of education and depressive symptoms were associated with NCI. Waist-to-hip ratio above the cut-off was strongly associated with NCI among HIV+ women. HIV+ women perform worse on cognitive measures compared to HIV+ men. The association of central obesity with NCI in HIV+ women should be noted.

Abstract
Background The correlation among high levels of total homocysteine, low levels of B12vitamin, and neurocognitive impairment in HIV negative patients has been the main research topic in some of the latest reviews. The aim of this study was to examine if the alteration of homocysteine, B12 vitamin, and D vitamins plasma levels was present in HIV-positive, and their relationship with cognitive function. Methods 57 HIV infected were enrolled and underwent the serum measurement of homocysteine, B12, and D vitamins. The neurocognitive evaluation investigated 5 cognitive domains, through a neuropsychological battery test Results Homocysteine was found to be elevated in 70.2% of cases, B12 vitamin mean levels were low in 8 participants (14.0%), and 8 patients had D hypovitaminosis (14.0%). Abnormal homocysteine levels were associated with worse performance of verbal fluency (p = 0.003) and worse executive function (Stroop E test p = 0.040). The 25-OH D hypovitaminosis was associated with worse performances in executive functions in three different tests: Stroop E (p = 0.049), Trail B (p = 0.035), and Wais Digit Span (p = 0.042). Pathological levels of B12 Vitamin were also associated to worse performances in executive functions (Trail B Test and Wais Digit Span respectively p = 0.002 and 0.029) and with a lower speed in psychomotor processing (Peg Board Test on dominant hand, p = 0.014). Conclusions In this study serum homocysteine, B12, and D vitamin levels are associated with neurocognitive performances; in fact low performance neurocognitive was correlated with hyperhomocysteine and low B12vitamin, and D vitamin levels. Evidence of the alteration of these parameters could facilitate the early identification of a neurocognitive impairment.

Abstract
Human immunodeficiency virus (HIV)-associated neurocognitive disorders can persist in many patients despite achieving viral suppression while on antiretroviral therapy (ART). Neurocognitive function over 48 weeks was evaluated using a Cogstate test battery assessing psychomotor function, attention, learning, and working memory in 293 HIV-1-infected, ART-experienced, and virologically suppressed adults. The ASSURE study randomized participants 1:2 to remain on tenofovir/emtricitabine (TDF/FTC) and ritonavir-boosted atazanavir (ATV/r) or simplify to abacavir/lamivudine + atazanavir (ABC/3TC + ATV). Neurocognitive z-scores were computed using demographically adjusted normative data and were classified as "impaired" (defined as either a z-score ≤ - 2 or having 2 or more standardized individual test z-scores ≤ - 1); while higher scores (equaling better performance) were classified as "normal". By z-scores, 54.7% of participants had impaired neurocognition at baseline and 50.2% at week 48. There were no significant differences (p < 0.05) in the baseline-adjusted performance between treatment groups for any individual test or by z-score. Specific demographic and medical risk factors were evaluated by univariate analysis for impact on neurocognitive performance. Factors with p < 0.10 were evaluated by backwards regression analysis to identify neurocognition-correlated factors after accounting for treatment, assessment, and baseline. Four risk factors at baseline for impaired neurocognition were initially identified: lower CD4 nadir lymphocyte counts, higher Framingham risk scores, and interleukin-6 levels, and a history of psychiatric disorder not otherwise specified, however none were found to moderate the effect of treatment on neurocognition. In this aviremic, treatment-experienced population, baseline-adjusted neurocognitive function remained stable and equivalent over 48 weeks with both TDF/FTC + ATV/r-treated and in the ART-simplified ABC/3TC + ATV treatment groups.

Peripheral and cerebrospinal fluid immune activation and inflammation in chronically HIV-infected patients before and after virally suppressive combination antiretroviral therapy (cART). J Neurovirol 2018; 24:679-694.

Abstract
Cerebrospinal fluid (CSF)/plasma HIV-RNA ratio has been associated with residual neurocognitive impairment on cART, leading us to hypothesize a specific peripheral and/or CSF immune feature in patients with high CSF/plasma ratio (≥ 1). In patients with diverse pre-cART CSF/plasma ratio (61/70 with CSF/plasma ratio < 1, L-CSF, 9/70 with CSF/plasma ratio ≥ 1, H-CSF), we investigated the effects of 12 months of effective cART on peripheral and CSF inflammatory markers, on T cell activation/maturation and HIV/CMV-specific intracellular cytokine pattern. We also studied the possible clinical association between peripheral/CSF pro-inflammatory milieu and neurocognitive screening tests (MMSE, FAB, IHDS). Prior to cART, the two groups were comparable for peripheral and CSF inflammation, T cell activation/proliferation and maturation, and HIV/CMV-specific response. Upon cART initiation, both H-CSF and L-CSF featured a significant reduction in plasma TNF-α and circulating CD8 activation, with a redistribution of memory/naïve T cell subsets in L-CSF alone. In the CSF compartment, cART seemed able to reduce pro-inflammatory cytokine/chemokine levels in both H-CSF and L-CSF patients. Interestingly, despite a reduction in the pro-inflammatory milieu, no changes were shown in neurocognitive screening tests in both patients' groups. We hereby show that 12-month cART is able to reduce intratechal and peripheral pro-inflammatory burden; a longer cART exposure and a more comprehensive neuropsychological evaluation might be necessary to gain a broader insight into the possible effects on neurocognitive performance.

Abstract
OBJECTIVES Considering the similarities between HIV-associated neurocognitive disorders (HAND) and neurodegenerative dementias and the frequency of executive dysfunctions among HIV-positive patients, we evaluated the accuracy of the Frontal Assessment Battery and Clock-Drawing Test together with the Three Questions Test and International HIV Dementia Scale to screen for HAND. METHODS A cross-sectional monocentric study was conducted from 2010 to 2017. The index tests were represented by the four screening tools; the reference standard was represented by a comprehensive neurocognitive battery used to investigate 10 cognitive domains. Patients were screened by a trained infectious diseases physician and those showing International HIV Dementia Scale scores ≤ 10 and/or complaining of neurocognitive symptoms were then evaluated by a trained neuropsychologist. RESULTS A total of 650 patients were screened and 281 received the full neurocognitive evaluation. HAND was diagnosed in 140 individuals. The sensitivity, specificity, correct classification rate and area under the receiver operating characteristic curve (AUROC) were, respectively, as follows: Frontal Assessment Battery, 40.7%, 95.1%, 68.3% and 0.81; International HIV Dementia Scale, 74.4%, 56.8%, 65.4% and 0.73; Clock-Drawing Test, 30.9%, 73.4%, 53.8% and 0.56; and Three Questions Test, 37.3%, 54.1% and 45.7%. Raising the Frontal Assessment Battery's cut-off to ≤ 16 improved its sensitivity, specificity and correct classification rate to 78.0%, 63.9% and 70.8%, respectively. CONCLUSIONS We observed poor screening performances of the Three Questions and Clock-Drawing Tests. While the International HIV Dementia Scale showed a poor specificity, the Frontal Assessment Battery showed the highest correct classification rate and a promising performance at different exploratory cut-offs.

Abstract
OBJECTIVE To compare the effect of immediate versus deferred antiretroviral treatment (ART) on neuropsychological test performance in treatment-naive HIV-positive adults with more than 500 CD4 cells/μl. DESIGN Randomized trial. METHODS The START parent study randomized participants to commence immediate versus deferred ART until CD4 less than 350 cells/μl. The START Neurology substudy used eight neuropsychological tests, at baseline, months 4, 8, 12 and annually, to compare groups for changes in test performance. Test results were internally standardized to z-scores. The primary outcome was the average of the eight test z-scores (QNPZ-8). Mean changes in QNPZ-8 from baseline were compared by intent-to-treat using longitudinal mixed models. Changes from baseline to specific time points were compared using ANCOVA models. RESULTS The 592 participants had a median age of 34 years; median baseline CD4 count was 629 cells/μl; the mean follow-up was 3.4 years. ART was used for 94 and 32% of accrued person-years in the immediate and deferred groups, respectively. There was no difference between the immediate and deferred ART groups in QNPZ-8 change through follow-up [-0.018 (95% CI -0.062 to 0.027, P = 0.44)], or at any visit. However, QNPZ-8 scores increased in both arms during the first year, by 0.22 and 0.24, respectively (P < 0.001 for increase from baseline). CONCLUSION We observed substantial improvement in neurocognitive test performance during the first year in both study arms, underlining the importance of using a control group in studies assessing neurocognitive performance over time. Immediate ART neither benefitted nor harmed neurocognitive performance in individuals with CD4 cell counts above 500 cells/μl.
