HIV, Depression, and Cognitive Impairment in the Era of Effective Antiretroviral Therapy

Clinical and sociodemographic characteristics of Alzheimer's disease and related dementias among people with HIV

INTRODUCTION

Alzheimer's disease and related dementias (AD/ADRD) continue to be a public health challenge. People with HIV (PWH) are at risk for neurocognitive disorders and may be at risk for AD/ADRD. However, studies examining clinical and sociodemographic factors associated with AD/ADRD among PWH are lacking. Therefore, the aim of this cross-sectional study was to determine the association between selected sociodemographic (age, gender, race, and rurality) and clinical (depression and encephalopathy) factors with AD/ADRD among PWH.

METHODS

Data were obtained from the South Carolina Revenue and Fiscal Affairs (RFA) Office and the South Carolina Alzheimer's Disease Registry ( N  = 13 390). Multivariable logistic regression models were used to determine the association between age, gender, race, rurality, depression, and encephalopathy, and AD/ADRD among PWH.

RESULTS

Among the study population ( N  = 13 390), 5% ( n  = 601) were found to have AD/ADRD. There was a dose-response relationship between age group and AD/ADRD whereas the age group increased, the association increased. For example, those who were aged 80 years and older were 80 times more likely to have AD/ADRD compared to those aged 18-29 years [adjusted odds ratio (aOR): 80.4; 95% confidence interval (CI): 40.2-160.8]. Additionally, male sex (aOR: 1.3; 95% CI: 1.9-1.6) and encephalopathy (aOR: 2.4; 95% CI: 1.9-3.2) were positively associated with AD/ADRD for PWH.

CONCLUSION

AD/ADRD interventions may be warranted among PWH, especially among older adults, men, and those with encephalopathy. Future studies should examine potential pathways between clinical and sociodemographic characteristics and AD/ADRD among PWH.

Relationship between social support and psychological symptoms in people living with HIV/AIDS, at risk of developing HIV - associated dementia

People living with HIV/AIDS often present neuropsychiatric symptoms, including cognitive and mood-related manifestations. Social support helps to cope with adverse events related to mental health. We aimed to analyze the relationship between satisfaction with social support and psychological symptoms in people living with HIV/AIDS at risk of developing HIV-associated dementia. An observational, cross-sectional, and correlational study was conducted. Assessment instruments included: sociodemographic questionnaire; Social Support Scale for People Living with HIV [Seidl & Tróccoli, 2006. Development of a scale for the social support evaluation in HIV/AIDS. Psicologia: Teoria e Pesquisa, 22(3), 317-326.], Brief Symptom Inventory (BSI) [Canavarro, 1999. Psychopathological Symptom Inventory - BSI. In M. G. M. R. Simões, & L. S. Almeida (Eds.), Psychological tests and tests in Portugal (Vol. II, pp. 87-109). SHO/APPORT.]; and International HIV Dementia Scale (IHDS). The sample consisted of 255 participants with a mean age of 48.16 years, 80.8% male, 68.6% living mostly with someone else. The strongest correlation was between the perception of availability of emotional support and availability of instrumental support, r (255) = 0.992; p < 0.001. Individuals with higher satisfaction with perceived emotional support had fewer psychological symptoms. Those with a higher Global Severity Index score on the BSI had a higher risk of dementia. An association was found between symptoms of psychological distress and a higher likelihood of developing HIV-related dementia. To reduce the risk of HIV-associated dementia, it is imperative to improve social support networks, which can serve as a vital clinical strategy.

Predicting Trajectories of Everyday Functioning in Adults Aging with HIV Using Latent Growth Mixture Modeling

As the U.S. population of people with HIV (PWH) ages, PWH exhibit high rates of adverse health outcomes including everyday functioning decline. We aimed to (1) identify trajectories of self-reported everyday functioning and (2) examine baseline predictors (demographics, cognitive domains, psychiatric and medical comorbidities, HIV-disease characteristics) of trajectories among PWH. 742 PWH completed up to five semi-annual visits over two years. Latent growth mixture modeling identified a linear 3-class solution with good statistical fit and interpretability. Most PWH (88%) had good baseline functioning with stability. Two classes had elevated baseline functional declines with worsening (7%) or improvement (5%). Greater depressive symptoms and motor skills impairment predicted higher odds of impaired functioning. Having chronic pulmonary disease increased odds of improvement, which may reflect connection to care, while older age increased odds of worsening. Most aging PWH demonstrate stable everyday functioning; however, interventions for depression and motor skills may improve functioning.

Anxiety, depression and neurocognitive disorder among HIV-infected people in penitentiary institutions of Azerbaijan

PURPOSE

This study aims to assess neurocognitive impairment, depression and anxiety level in HIV-infected individuals in penitentiary institutions of Azerbaijan.

DESIGN/METHODOLOGY/APPROACH

A cross-sectional design was used to recruit incarcerated individuals in penitentiary institutions of Azerbaijan meeting the inclusion criteria (diagnosed with HIV). Participants completed standardized assessments to screen anxiety and depression symptoms, hospital anxiety and depression scale and neurocognitive functioning and mini mental status examination. Demographic and clinical data, including age, gender, HIV disease progression, antiretroviral therapy adherence, history of substance abuse and duration of incarceration, were also collected as covariates of interest. The study was approved by Azerbaijan Medical University Ethics Committee (P.23 / 19.05.2022). Data were analyzed using student-Bonferroni and H-Kruskal-Wallis tests. Variance analysis was conducted using the ANOVA test, while discriminant analyses involved the χ2-Pearson test, through SPSS software, version 26.

FINDINGS

Of the 88 HIV positive patients who agreed to participate, 99% were male, with a median age of 44 years (range: 30-62), median CD4 count 453.1 cells/µl (range: 153-1,290). The prevalence of HIV-associated neurocognitive disorder was 72.7%. Occurrence of comorbid depression and anxiety symptoms was found to be 72% and 67%, respectively. Most patients (59.1%) were HIV-positive for more than five years. Increased depression and anxiety levels were identified mostly in first two years after admission to prison (p < 0.05). HIV-associated neurocognitive disorder was most commonly found among depressed patients (p = 0.009).

ORIGINALITY/VALUE

The findings of this study provide valuable insights into the cooccurrence and interrelationships between anxiety, depression and neurocognitive disorders in individuals with HIV in prisons. It highlights the unique intersection of HIV infection, mental health challenges and incarceration in a country where research on HIV-related issues in prisons is still developing. Ultimately, this study seeks to contribute to identify targeted interventions that address the mental health needs of incarcerated individuals living with HIV in Azerbaijan, promoting their overall well-being and quality of life.

Effect of a WeChat-Based Hybrid Intervention on the Adaptation Outcomes of People Living With HIV/AIDS: Pilot Randomized Controlled Trial

BACKGROUND

People living with HIV/AIDS face multiple challenges that collectively impede their adaptation outcomes. These outcomes include quality of life (QoL), acceptance of illness, mental health (including symptoms of anxiety and depression), and antiretroviral therapy (ART) adherence. While existing evidence addresses specific challenges, it often overlooks the interactions among the various problems people living with HIV/AIDS encounter. The comprehensive-task disease management framework and positive self-management framework provide a theoretical basis for understanding the adaptation process. A culturally tailored, theory-based intervention may be necessary and effective in facilitating better adaptation outcomes for people living with HIV/AIDS.

OBJECTIVE

This study aimed to evaluate the effect of a hybrid intervention called AiCare (Adaptation intervention with Comprehensive-task disease management framework to achieve renormal life) on improving QoL, acceptance of illness, mental health (anxiety and depression), and ART adherence among people living with HIV/AIDS in China.

METHODS

We conducted a 2-arm randomized controlled trial, recruiting 92 people living with HIV/AIDS from an HIV clinic in Hunan, China. Participants were randomly assigned in a 1:1 ratio to either the control group (receiving standard care) or the intervention group (receiving AiCare in addition to standard care). All analyses were performed from an intention-to-treat perspective. Sociodemographic and HIV-specific clinical characteristics, along with key adaptation outcomes-including QoL, acceptance of illness, mental health (anxiety and depression), and ART adherence-were assessed at baseline (T0), post intervention (T1), and 3 months post intervention (T2). We used generalized estimating equation models and difference-in-difference analysis to evaluate the interventions' effects.

RESULTS

The difference-in-difference model showed that at T1, the intervention group experienced significant improvements compared to the control group. QoL increased by 6.35 (95% CI 2.62-10.93, P=.001), acceptance of illness improved by 4.49 (95% CI 2.29-6.68, P<.001), and anxiety decreased by 2.15 (95% CI 1.19-3.11; P=.01). At T2, the intervention group's improvement in QoL was not statistically significant (β 3.62, 95% CI -1.53 to 8.77; P=.17). However, acceptance of illness remained significantly improved by 3.65 (95% CI 1.22-6.08; P=.003), and anxiety decreased by 1.58 (95% CI 0.42-2.74; P=.007). No significant changes were observed in depression or ART adherence between the intervention and control groups. Feedback regarding the AiCare program indicated its acceptability and feasibility.

CONCLUSIONS

The AiCare program demonstrated promising effects in improving disease adaptation outcomes among people living with HIV/AIDS, notably in enhancing QoL, fostering acceptance of illness, and mitigating anxiety symptoms. These findings underscore the hybrid program's potential clinical utility to facilitate the adaptation of people living with HIV/AIDS.

Evidence from high-income countries on the effectiveness of psychosocial interventions to improve mental health, wellbeing and quality of life for adults living with HIV: a systematic review and meta-analysis

INTRODUCTION

There is a need to synthesize recent evidence on the effectiveness of psychosocial interventions to improve mental health, quality of life and wellbeing in adults living with HIV in high-income countries. A systematic review and meta-analysis was conducted to address this research gap.

METHODS

Medline, Embase, Psychinfo and Web of science were searched (from 2008 to December 2023). In total, 67 randomized controlled trials (RCTs) of psychosocial intervention among adults living with HIV in high-income countries were eligible.

RESULTS

In the meta-analysis, there was an overall positive effect of interventions on reducing depression (N = 40; standardized mean difference [SMD] -0.19 [95% CI: -0.29, -0.10]), anxiety (N = 15; SMD -0.12 [-0.23, -0.02]), stress (N = 13; SMD -0.22 [-0.41, -0.04]), and other measures of poor wellbeing (N = 19; SMD -0.18 [-0.35, -0.02]) and increasing levels of coping/self-efficacy (N = 8; SMD 0.17 [0.04, 0.31]). For depression, interventions that used symptom screening above a threshold score to identify eligible individuals were more effective than those without such an eligibility criterion (SMD -0.29 vs. -0.10, p = 0.023). Interventions compared to standard care controls had a greater effect on depression versus interventions compared to not standard care controls, when the latter category included standard care controls that received intentional support (SMD -0.28 vs. -0.11, p = 0.035). There was also weak evidence of an overall positive effect on: reducing stigma (N = 7; SMD -0.17 [-0.35, 0.02]), and improving social support/participation (N = 6; SMD 0.17 [-0.02, 0.35]), mental health quality of life (N = 12; SMD 0.09 [-0.01, 0.19]), physical health quality of life (N = 11; SMD 0.07 [-0.02, 0.16]) and quality of social life (N = 6; SMD 0.10 [-0.04, 0.24]). There was no evidence found for an effect on loneliness, although data were limited.

DISCUSSION

Pooled effect estimates were small or small tomoderate. In line with previous literature, there was no evidence of differential effects on depression according to the intervention type (psychotherapeutic vs. other).

CONCLUSIONS

Evidence from RCTs suggest that psychosocial interventions are effective in improving mental health for adults living with HIV in high-income settings. Interventions were more effective at reducing depression when targeted at those screening positive for mental health symptoms and when compared to a standard care only control group. There was some evidence that longer, more intensive interventions were more effective.

Depressive Symptoms and HIV Viral Suppression: A Systematic Review and Meta-analysis

Previous research suggests that depression impacts HIV outcomes, including viral suppression. This meta-analysis quantifies the association between depression and HIV viral suppression. A systematic literature search was conducted in PubMed, Web of Science, EBSCO, and OVID to identify studies published through 2012 to 2022. The software Rayyan was used to evaluate eligibility of studies, and the 2020 Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines were used for abstracting data. A random effects meta-analysis was performed using Review Manager 5.4.1. Of the 1911 articles screened, 16 studies were included covering 80,103 participants. The results showed individuals without depression were more likely to achieve HIV viral suppression or undetectable viral load compared to individuals with depression (OR 1.30; 95%CI 1.15, 1.48; I2 = 76%). Subgroup analysis indicated this effect was significant among the general population of people living with HIV (n = 75,353; OR 1.32; 95%CI 1.12, 1.55; I2 = 85%) and cisgender women living with HIV (n = 4553; OR 1.28; 95%CI 1.09, 1.50; I2 = 16%), but not among cisgender men living with HIV (most identified as men who have sex with men) (n = 197; OR 2.13; 95%CI 0.43, 10.61; I2 = 83%). This meta-analysis shows a significant positive association between the absence of depression and achieving HIV viral suppression overall and among the subgroup of cisgender women. Public health interventions for people living with HIV should include strategies to identify and address the depressive symptoms that impact adherence to treatment, increase the risk of psycho-behavioral co-morbidities, and exacerbate social or structural factors impeding viral suppression.

Dementia prevalence and risk factors in people with and without HIV in Malawi: A medical record review

BACKGROUND

Sub-Saharan Africa (SSA) is experiencing a rapid increase in its aging population, including people living with human immunodeficiency virus (HIV) (PLHIV). The purpose of this study was to determine the prevalence of dementia among PLHIV and people without HIV (POHIV) in Malawi.

METHODS

We conducted a retrospective medical record review of 400 consecutive patients from a single tertiary health center (200 PLHIV from an HIV clinic and 200 POHIV from an outpatient clinic) in Lilongwe, Malawi.

RESULTS

The overall rate of dementia was higher in PLHIV than that in POHIV (22% vs 10%; p = 1.4e). Older age, unknown employment or unemployed, and depression were significant risk factors for dementia for PLHIV, while older age and depression were significant among POHIV.

DISCUSSION

Our study confirmed the increased risk of dementia in PLHIV and provides valuable groundwork for future dementia studies to accurately examine the prevalence and risk factors of dementia in SSA, including Malawi.

HIGHLIGHTS

Malawians, in SSA, face the double burden of HIV AD and related dementias. We conducted a retrospective medical record review to assess dementia prevalence and risk factors. Dementia prevalence was higher in PLHIV than in POHIV. Older age, unknown employment or unemployed, and depression were risk factors for dementia in PLHIV. Our findings, reflecting the current diagnosing and medical documenting practice in Malawi, provide valuable groundwork for future dementia research in Malawi.

Aging with HIV and HIV-associated neurocognitive impairment

Antiretroviral therapy (ART) is the most effective therapeutic intervention for HIV infection. With improved survival, comorbidities, including neuropsychiatric and HIV-associated neurocognitive impairment (NCI) are of increasing concern to aging people with HIV (PWH). The clinical features and the inter-individual variability of the aging process confound the elucidation of the diagnosis and underlying mechanisms of cognitive dysfunction in aging PWH. Herein, we review the clinical aspects of HIV-associated NCI in the aging PWH contrasting to the normative neuro-aging seen in people without HIV (PWoH) and address the growing role of biomarkers to predict the onset of age-related diseases in PWH and their clinical significance. There is an urgent need for further research into the role of specific immune brain biomarkers in predicting the aging process and how these biomarkers may assist in understanding the mechanisms and possible prognosis of age-related neurocognitive comorbidities in aging PWH as an endpoint for interventional studies.

Acute nicotine vapor attenuates sensorimotor gating deficits in HIV-1 transgenic rats

RATIONALE

Despite improved life expectancy of people with HIV (PWH), HIV-associated neurocognitive impairment (NCI) persists, alongside deficits in sensorimotor gating and neuroinflammation. PWH exhibit high smoking rates, possibly due to neuroprotective, anti-inflammatory, and cognitive-enhancing effects of nicotine, suggesting potential self-medication.

OBJECTIVES

Here, we tested the effects of acute nicotine vapor exposure on translatable measures of sensorimotor gating and exploratory behavior in the HIV-1 transgenic (HIV-1Tg) rat model of HIV.

METHODS

Male and female HIV-1Tg (n = 28) and F344 control rats (n = 29) were exposed to acute nicotine or vehicle vapor. Sensorimotor gating was assessed using prepulse inhibition (PPI) of the acoustic startle response, and exploratory behavior was evaluated using the behavioral pattern monitor (BPM).

RESULTS

Vehicle-treated HIV-1Tg rats exhibited PPI deficits at low prepulse intensities compared to F344 controls, as seen previously. No PPI deficits were observed in nicotine-treated HIV-1Tg rats, however. Nicotine vapor increased locomotor activity across genotypes. Cotinine analyses confirmed comparable levels of the primary metabolite of nicotine across genotypes.

CONCLUSIONS

Previous findings of PPI deficits in HIV-1Tg rats were replicated and, importantly, attenuated by acute nicotine vapor administration. Evidence for similar cotinine levels suggest a nicotine-specific effect in HIV-1Tg rats. Therefore, acute nicotine administration may be beneficial for attenuating sensorimotor deficits in PWH. Future studies should determine the long-term effects of nicotine vapor on similar HIV/NCI-relevant behaviors.

Mental health phenotypes of well-controlled HIV in Uganda

Introduction

The phenotypic expression of mental health (MH) conditions among people with HIV (PWH) in Uganda and worldwide are heterogeneous. Accordingly, there has been a shift toward identifying MH phenotypes using data-driven methods capable of identifying novel insights into mechanisms of divergent MH phenotypes among PWH. We leverage the analytic strengths of machine learning combined with inferential methods to identify novel MH phenotypes among PWH and the underlying explanatory features.

Methods

A total of 277 PWH (46% female, median age = 44; 93% virally suppressed [<50copies/mL]) were included in the analyses. Participants completed the Patient Health Questionnaire (PHQ-9), Beck Anxiety Inventory (BAI), and the PTSD Checklist-Civilian (PCL-C). A clustering pipeline consisting of dimension reduction with UMAP followed by HBDScan was used to identify MH subtypes using total symptom scores. Inferential statistics compared select demographic (age, sex, education), viral load, and early life adversity between clusters.

Results

We identified four MH phenotypes. Cluster 1 (n = 76; PTSD phenotype) endorsed clinically significant PTSD symptoms (average PCL-C total score > 33). Clusters 2 (n = 32; anxiety phenotype) and 3 (n = 130; mixed anxiety/depression phenotype) reported minimal PTSD symptoms, with modest BAI (Cluster 2) and PHQ-9 (Cluster 3) elevations. Cluster 4 (n = 39; minimal symptom phenotype) reported no clinical MH symptom elevations. Comparisons revealed higher rates of sexual abuse during childhood among the PTSD phenotype vs. the minimal symptom phenotype (p = 0.03).

Discussion

We identified unique MH phenotypes among PWH and confirmed the importance of early life adversity as an early risk determinant for unfavorable MH among PWH in adulthood.

Virtual Reality-Based Psychological Intervention for Young Adults Living With HIV: Protocol for a Randomized Controlled Trial

BACKGROUND

Young adults (15-24 years old) living with HIV may experience pressure both from HIV infection and social role change problems, resulting in a series of psychological problems such as depression and anxiety. Effective psychological intervention can improve their mental health and quality of life.

OBJECTIVE

The study aims to explore the effectiveness of VR-based mental intervention on young adults living with HIV. The application and advantages of virtual reality (VR) in children's psychotherapy provide new ideas for psychological intervention for young adults living with HIV.

METHODS

We use the qualitative interviews and questionnaire results as well as guided by classical psychotherapy to create a personalized psychological intervention system for young adults living with HIV through VR technology, which is based on the long-term AIDS treatment cohort and infectious diseases cohort of children. We use the mental scales and biochemical indexes as the outcomes, conducting a prospective randomized controlled trial to verify the feasibility and effectiveness of the VR psychological intervention system.

RESULTS

The study began enrollment in September 2023. To date, 160 participants have finished the baseline questionnaires.

CONCLUSIONS

The study results might provide a scientific basis for accurate psychological treatment among young adults living with HIV in the future.

HIV Stigma is Associated with Two-Year Decline in Cognitive Performance Among People with HIV

HIV stigma is associated with suboptimal clinical outcomes and has been cross-sectionally linked to cognitive deficits in people with HIV (PWH). However, it is unclear whether HIV stigma precedes cognitive decline or vice versa. We examined associations in 303 adult PWH (mean age 50.01 (11.91) years; 46% female; 67% non-Hispanic Black) between the abbreviated Berger Stigma Scale score and longitudinal change across the NIH Toolbox Cognition Battery measures. 89% of participants reported experiencing HIV stigma. In unadjusted analyses, greater HIV stigma was associated with worse attention performance at yearly follow-up visits (B = -0.07, 95% CI = -0.13 - -0.01, p = 0.025). When adjusting for clinicodemographic variables, HIV stigma was associated with worse processing speed and global cognition at yearly follow-up visits. This finding suggests that HIV stigma precedes subsequent cognitive decline and highlights the importance of reducing stigma to improve cognitive functioning among PWH.

Neurocognitive function and its influencing factors in people living with HIV/AIDS

OBJECTIVES

The prevalence of human immunodeficiency virus (HIV) associated neurocognitive disorders (HAND) in people living with HIV/acquired immunodeficiency syndrome (PLWHA) worldwide is as high as 42.6%. This study aims to investigate the neurocognitive function status and its influencing factors in PLWHA, providing evidence for early identification and intervention of neurocognitive impairment in this population.

METHODS

PLWHA aged 18 and above who received outpatient or inpatient care at the First Hospital of Changsha between June and August 2019 were included. Sociodemographic and HIV-related information were collected. Neurocognitive function was assessed using the Brief Neurocognitive Screen (BNCS), which includes the Digit Symbol Test (DST) and Trail Making Test A and B (TMT-A and TMT-B). Impaired neurocognitive function was defined as abnormal scores in at least one dimension (DST score <30, TMT-A time >60 seconds, TMT-B time >90 seconds).

RESULTS

A total of 375 PLWHA were included, of whom 212 (56.5%) exhibited neurocognitive impairment. Higher impairment rates were observed among females, individuals aged ≥50 years, those with primary education or below, and those who were married/cohabiting (all P<0.05). Heterosexual transmission accounted for the majority of infections (233 cases, 62.1%), with a significantly higher rate of neurocognitive impairment (69.1%) compared to homosexual transmission and unknown routes (P<0.001). Higher WHO clinical stages were associated with increased impairment rates (P<0.001). PLWHA with a nadir CD4+ T cell count <200 cells/mm3 or an infection duration ≥5 years had significantly higher impairment rates than those with higher CD4+ T cell count or shorter infection durations (both P<0.05). Logistic regression analysis showed that patients with a nadir CD4+ T cell count <200 cells/mm3 had a significantly higher risk of neurocognitive impairment (OR=2.461, 95% CI 1.116 to 5.427). Compared to WHO stage I, the risk increased progressively in stage II (OR=6.005, 95% CI 2.906 to 12.407), stage III (OR=6.989, 95% CI 2.502 to 19.523), and stage IV (OR=22.059, 95% CI 7.289 to 66.760; all P<0.05).

CONCLUSIONS

Potential risk factors for neurocognitive impairment in PLWHA include low nadir CD4+ T cell counts and advanced WHO clinical stages. The lower the CD4+ T cell count and the higher the clinical stage, the greater the risk of neurocognitive dysfunction.

Comparison of smoking behaviors and associated factors between HIV-infected and uninfected men in Guilin, China: a case-control study

Background

Smoking is highly prevalent among HIV-infected individuals and is associated with high morbidity and mortality. Studies on smoking among HIV-infected individuals in China, especially compared to uninfected individuals, are scarce.

Purpose

This study aimed to investigate and compare the prevalence and factors associated with smoking between HIV-infected and uninfected men in Guilin, China.

Methods

A survey was conducted among 1,395 HIV-infected men at Guilin Third People's Hospital from June to December 2022, with a 1:2 age (±1 year) and education-matched control group of 2,790 HIV-uninfected men, whose data were collected from March to August 2023. Both groups completed an online questionnaire on smoking behaviors and relevant characteristics, with a comparative analysis of associated factors conducted using chi-square tests and multivariable logistic regressions.

Results

The rates of former smokers were comparable between HIV-infected and uninfected men [12.3% (95% CI: 10.7-13.9%) vs. 12.0% (95% CI: 10.9-13.1%)], but the current smoking rate was significantly higher in the infected group than in the uninfected group [37.6% (95% CI: 35.2-40.0%) vs. 27.6% (95% CI: 25.9-29.3%), p < 0.05]. In both groups, the following factors were significantly associated with smoking: higher income, presence of chronic diseases, negative coping styles, lower social support, and having depression, anxiety, and suicidal ideation. Additionally, in HIV-infected men, the following factors were exclusively associated with smoking: heterosexual HIV transmission route, lower CD4+ T cell count, longer duration of antiretroviral therapy (ART), and drug use.

Conclusion

HIV-infected men had higher smoking rates than their uninfected counterparts, indicating that HIV diagnosis may be a critical timing to initiate behavioral changes and deliver smoking cessation interventions. Furthermore, multiple demographic, clinical, and psychosocial factors were associated with smoking, indicating the need to develop and implement comprehensive smoking cessation prevention and intervention programs.

Impact of arterial stiffness on health-related quality of life in older Thai adults with treated HIV infection: a multicenter cohort study

PURPOSE

Despite advancements in antiretroviral therapy (ART) that extend life expectancy, older adults with HIV (OAHIV) face elevated cardiovascular disease risks. This study examines the impact of arterial stiffness on health-related quality of life (HRQoL) among OAHIV in rural Northern Thailand.

METHODS

We conducted a 5-year prospective cohort study from 2015, including 338 OAHIV aged ≥ 50 without prior cardiovascular disease who received ART in 12 community hospitals in Chiang Mai. Arterial stiffness was assessed using Cardio-Ankle Vascular Index (CAVI), with values ≥ 8 indicating significant stiffness. HRQoL was measured using the MOS-HIV Health Survey at baseline, one year, and five years. Analysis adjusted for HIV/AIDS severity, cardiovascular comorbidities, and socioeconomic factors.

RESULTS

Elevated CAVI (≥ 8) was associated with lower HRQoL scores. The elevated CAVI group showed lower physical health summary scores (average difference:- 2.2 points, 95%CI: - 3.5 to - 0.9) and mental health summary scores (average difference: - 1.2 points, 95%CI: - 2.2 to - 0.3) compared to the normal CAVI group (CAVI < 8).

CONCLUSION

Findings highlight the importance of routine screening for arterial stiffness and support the implementation of comprehensive care strategies that incorporate cardiovascular risk management. Such approaches could guide public health interventions and clinical practices to enhance the overall health and well-being of OAHIV, potentially through targeted cardiovascular risk reduction programs and personalized care plans. However, the study's regional focus in rural Northern Thailand and participant attrition over the five-year period limit the generalizability of the findings. Future research in diverse settings with larger sample sizes is needed to confirm these results.

Neurocognition and its predictors in a linguistically and culturally diverse cohort of people with HIV

Objective: HIV/AIDS disproportionately affects Black and Latino people in the United States, yet there is a lack of research on predictors of neurocognitive outcomes in these groups. We examined neurocognitive performance and its key predictors across White, Black, and Latino people with HIV (PWH). Method: Participants included 586 PWH of White, Black, and Latino (English- and Spanish-speaking) background. Neurocognition was assessed via demographically-adjusted Fluid Cognition Composite T-scores from the NIH-Toolbox cognition battery, and individual tests comprising this composite. Predictors examined included sociodemographic and HIV disease characteristics, and medical, psychiatric and substance comorbidities. Results: Compared to White PWH, English-speaking Latino PWH had lower T-scores on the Fluid Cognition Composite, as well as Flanker Inhibition and Picture Sequence Memory tests. While there were no other significant group differences on Fluid Cognition, both Latino PWH language groups performed worse than Black PWH on Flanker Inhibition, and Black PWH performed worse than White PWH on List Sorting. Separate multivariable linear regression models by ethnic/racial/language group showed that significant correlates of worse Fluid Cognition included depressive symptoms among White PWH; hepatitis C co-infection among Black PWH; hypertension among English-speaking Latino PWH; and higher estimated duration of HIV disease and depressive symptoms in Spanish-speaking Latino PWH. Conclusions: Findings suggest worse neurocognition among English-speaking Latino PWH compared to Whites. Predictors of neurocognitive function among PWH differ across ethnic/racial and language groups. Consideration of these HIV disease characteristics and comorbidities may be valuable in developing targeted culturally-relevant interventions aimed at ameliorating neurocognitive dysfunction among diverse PWH.

Improving Sleep in People with HIV and Chronic Pain: A Pilot Study of Brief Behavioral Treatment for Insomnia

OBJECTIVES

Insomnia and chronic pain are common symptoms in people with HIV. Poor sleep has been associated with chronic pain. While cognitive behavioral therapy for insomnia improves insomnia in clinical populations, there are barriers to people with HIV accessing treatment including the lack of trained providers and lengthy sessions. Only one study has examined the efficacy of brief behavioral treatment for insomnia (BBTI) in people with HIV. This study examined BBTI effects on sleep and pain in people with HIV.

METHODS

Ten adults with HIV and chronic pain completed a 4-week, telephone-delivered BBTI treatment. A control group (n = 10) completed a brief mindfulness training (BMT). The Insomnia Severity Index and Brief Pain Inventory were used to assess insomnia severity and pain outcomes, respectively.

RESULTS

There was a significant interaction between intervention and time on insomnia severity, F (2,14) = 5.7, p = .02, partial η2 = 0.45). The BBTI group demonstrated significant improvements in insomnia severity from pre- to post-intervention (p < .001) and from pre-intervention to one-month post-intervention (p = .001) compared to the BMT group. There was a significant interaction between intervention and time on pain interference, F (1,18) = 4.9, p = .02, partial η2 = 0.27). The BBTI group demonstrated a significant decrease in pain interference from pre- to post-intervention (p < .001) compared to the BMT group.

CONCLUSIONS

This pilot study demonstrated that BBTI improved insomnia in people with HIV for up to one-month post-treatment. Novel preliminary evidence suggests that BBTI may also improve pain outcomes in people with HIV.

People with HIV exhibit spectrally distinct patterns of rhythmic cortical activity serving cognitive flexibility

Despite effective antiretroviral therapy, cognitive impairment remains prevalent among people with HIV (PWH) and decrements in executive function are particularly prominent. One component of executive function is cognitive flexibility, which integrates a variety of executive functions to dynamically adapt one's behavior in response to changing contextual demands. Though substantial work has illuminated HIV-related aberrations in brain function, it remains unclear how the neural oscillatory dynamics serving cognitive flexibility are affected by HIV-related alterations in neural functioning. Herein, 149 participants (PWH: 74; seronegative controls: 75) between the ages of 29-76 years completed a perceptual feature matching task that probes cognitive flexibility during high-density magnetoencephalography (MEG). Neural responses were decomposed into the time-frequency domain and significant oscillatory responses in the theta (4-8 Hz), alpha (10-16 Hz), and gamma (74-98 Hz) spectral windows were imaged using a beamforming approach. Whole-brain voxel-wise comparisons were then conducted on these dynamic functional maps to identify HIV-related differences in the neural oscillatory dynamics supporting cognitive flexibility. Our findings indicated group differences in alpha oscillatory activity in the cingulo-opercular cortices, and differences in gamma activity were found in the cerebellum. Across all participants, alpha and gamma activity in these regions were associated with performance on the cognitive flexibility task. Further, PWH who had been treated with antiretroviral therapy for a longer duration and those with higher current CD4 counts had alpha responses that more closely resembled those of seronegative controls, suggesting that optimal clinical management of HIV infection is associated with preserved neural dynamics supporting cognitive flexibility.

Neurosymptomatic HIV-1 CSF escape is associated with replication in CNS T cells and inflammation

During antiretroviral therapy (ART), most people living with HIV-1 have undetectable HIV-1 RNA in their plasma. However, they occasionally present with new or progressive neurologic deficits and detectable HIV-1 RNA in the cerebrospinal fluid (CSF), a condition defined as neurosymptomatic HIV-1 CSF escape (NSE). We explored the source of neuropathogenesis and HIV-1 RNA in the CSF during NSE by characterizing HIV-1 populations and inflammatory biomarkers in CSF from 25 individuals with NSE. HIV-1 populations in the CSF were uniformly drug resistant and adapted to replication in CD4+ T cells, but differed greatly in genetic diversity, with some having low levels of diversity similar to those observed during untreated primary infection and others having high levels like those during untreated chronic infection. Higher diversity in the CSF during NSE was associated with greater CNS inflammation. Finally, optimization of ART regimen was associated with viral suppression and improvement of neurologic symptoms. These results are consistent with CNS inflammation and neurologic injury during NSE being driven by replication of partially drug-resistant virus in CNS CD4+ T cells. This is unlike nonsuppressible viremia in the plasma during ART, which typically lacks clinical consequences and is generated by virus expression without replication.

Executive Function and Adherence in Children and Adolescents Living with HIV: Evidence from the HIV-associated Neurocognitive Disorders in Zambia (HANDZ) Study

Introduction

Executive function (EF) may be impaired in people with human immunodeficiency virus (HIV) infection, and poor EF may affect medication adherence. However, there is little data on EF in children with HIV in sub-Saharan Africa.

Methods

208 children/adolescents with perinatally acquired HIV and 208 HIV-exposed uninfected controls were recruited in Zambia for this prospective cohort study. EF was measured using performance-based, self-report, and parental report measures. Adherence over one year of follow-up was assessed through questionnaires and viral load measurement.

Results

Children with HIV performed significantly worse on all three measures of EF. Lower parental rating of EF was associated with poorer antiretroviral therapy adherence (OR: 1.5, 95% CI = 1.02 - 2.2, p = 0.04).

Conclusion

Children with HIV have EF impairments which may lead to consequences like poor medication adherence and treatment failure. Interventions to improve EF or compensate for impaired EF may be necessary in this population.

Life expectancy and mental related burden of disease among people living with HIV/AIDS

Mental health problems leads to serious disease burden among people living with HIV/AIDS (PLHIV). The study aimed at measuring the mental disorders-caused burden of disease based on PLHIV in mainland China. The data used was from the national HIV/AIDS case reporting system, life expectancy (LE) and LE-eliminated suicide were evaluated by the life-table method. The total YLLs and YLLs caused by suicide in each age group were calculated. The disability weights were estimated by the scale of depression symptoms (CES-D) from the multi-center cross-sectional survey, then calculated the corresponding YLDs as a burden of mental illness among PLHIV. Results showed that the LE had been prolonged by implementing antiviral therapy for PLHIV. The proportion of YLLs caused by suicide was the highest (5·46%) in the 15-24 age group. The YLDs in the 25-34 age group were the highest. The YLLs caused by suicide in males were higher than those in the same age group of females. The YLDs and YLLs were higher in heterosexual-infected PLHIV than in homosexual-infected PLHIV, except for YLLs in the 25-34 age group. In summary, this study first provided localized data on the disease burden caused by mental health problems among PLHIV.

Acute nicotine vapor normalizes sensorimotor gating and reduces locomotor activity deficits in HIV-1 transgenic rats

Rationale

Despite improved life expectancy of people with HIV (PWH), HIV-associated neurocognitive impairment (NCI) persists, alongside deficits in sensorimotor gating and neuroinflammation. PWH exhibit high smoking rates, possibly due to neuroprotective, anti-inflammatory, and cognitive-enhancing effects of nicotine, suggesting potential self-medication.

Objectives

Here, we tested the effects of acute nicotine vapor exposure on translatable measures of sensorimotor gating and exploratory behavior in the HIV-1 transgenic (HIV-1Tg) rat model of HIV.

Methods

Male and female HIV-1Tg and F344 control rats (n=57) were exposed to acute nicotine or vehicle vapor. Sensorimotor gating was assessed using prepulse inhibition (PPI) of the acoustic startle response, and exploratory behavior was evaluated using the behavioral pattern monitor (BPM).

Results

Vehicle-treated HIV-1Tg rats exhibited PPI deficits at low prepulse intensities compared to F344 controls, as seen previously. No PPI deficits were observed in nicotine-treated HIV1-Tg rats, however. HIV-1Tg rats were hypoactive in the BPM relative to controls, whilst nicotine vapor increased activity and exploratory behavior across genotypes. Cotinine analyses confirmed comparable levels of the primary metabolite of nicotine across genotypes.

Conclusions

Previous findings of PPI deficits in HIV-1Tg rats were replicated and, importantly, attenuated by acute nicotine vapor. Evidence for similar cotinine levels suggest a nicotine-specific effect in HIV-1Tg rats. HIV-1Tg rats had reduced exploratory behavior compared to controls, attenuated by acute nicotine vapor. Therefore, acute nicotine may be beneficial for remediating sensorimotor and locomotor activity deficits in PWH. Future studies should determine the long-term effects of nicotine vapor on similar HIV/NCI-relevant behaviors.

Depression symptoms and suicidal ideation among HIV infected Rwandans: the mediating and moderating effects of complicated grief and substance abuse

BACKGROUND

People with HIV/AIDS (PWHA) have 7-36 times greater risk for completed suicide associated with depression symptoms compared to general population. However, no study has sufficiently analyzed the mediating or moderating variables of the relationship between depression and suicidal ideation in Rwanda.

OBJECTIVES

This study aimed to examine how complicated grief mediates and substance abuse moderates the effects of depression symptoms on suicidal ideation.

METHODS

Data were collected from a convenient sample of 140 participants (M-age = 38.79 years, SD = 10.218) receiving antiretroviral therapy (ART) at Remera Health Center in a cross-sectional study. Multiple linear regression and Sobel test were used to examine the relationships between depression symptoms, complicated grief, suicidal ideation, and substance abuse.

RESULTS

The results indicated that 29% of the sample had clinically significant symptoms of depression and 18% had suicidal ideation. The interaction between substance abuse and depression symptoms (β = .468, t = 8.02, p = 0.000) was a significant predictor, explaining the 55.7% of variance in suicidal ideation. Furthermore, the Sobel test demonstrated that complicated grief mediated the effects of depression symptoms (t = 4.67, SE = 0.0101, p ≤ 0.001) on suicidal ideation.

CONCLUSION

The results suggest that depression symptoms are associated with an increased risk of suicidal ideation, and this risk significantly amplified in the presence of complicated grief and substance abuse. These findings highlight the importance of integrating mental health services, particularly those addressing depression, complicated grief, and substance abuse, into HIV care programs to mitigate the risk of suicidal ideation among PWHA.

The beneficial effect of fluoxetine on behavioral and cognitive changes in chronic experimental Chagas disease unveils the role of serotonin fueling astrocyte infection by Trypanosoma cruzi

BACKGROUND

In Chagas disease (CD), a neglected tropical disease caused by the parasite Trypanosoma cruzi, the development of mental disorders such as anxiety, depression, and memory loss may be underpinned by social, psychological, and biological stressors. Here, we investigated biological factors underlying behavioral changes in a preclinical model of CD.

METHODOLOGY/PRINCIPAL FINDINGS

In T. cruzi-infected C57BL/6 mice, a kinetic study (5 to 150 days postinfection, dpi) using standardized methods revealed a sequential onset of behavioral changes: reduced innate compulsive behavior, followed by anxiety and depressive-like behavior, ending with progressive memory impairments. Hence, T. cruzi-infected mice were treated (120 to 150 dpi) with 10 mg/Kg/day of the selective serotonin reuptake inhibitor fluoxetine (Fx), an antidepressant that favors neuroplasticity. Fx therapy reversed the innate compulsive behavior loss, anxiety, and depressive-like behavior while preventing or reversing memory deficits. Biochemical, histological, and parasitological analyses of the brain tissue showed increased levels of the neurotransmitters GABA/glutamate and lipid peroxidation products and decreased expression of brain-derived neurotrophic factor in the absence of neuroinflammation at 150 dpi. Fx therapy ameliorated the neurochemical changes and reduced parasite load in the brain tissue. Next, using the human U-87 MG astroglioma cell line, we found no direct effect of Fx on parasite load. Crucially, serotonin/5-HT (Ser/5-HT) promoted parasite uptake, an effect increased by prior stimulation with IFNγ and TNF but abrogated by Fx. Also, Fx blocked the cytokine-driven Ser/5-HT-promoted increase of nitric oxide and glutamate levels in infected cells.

CONCLUSION/SIGNIFICANCE

We bring the first evidence of a sequential onset of behavioral changes in T. cruzi-infected mice. Fx therapy improves behavioral and biological changes and parasite control in the brain tissue. Moreover, in the central nervous system, cytokine-driven Ser/5-HT consumption may favor parasite persistence, disrupting neurotransmitter balance and promoting a neurotoxic environment likely contributing to behavioral and cognitive disorders.

Multimodal Approach to Neurocognitive Function in People Living with HIV in the cART Era: A Comprehensive Review

Combination antiretroviral treatment (cART) has revolutionized the management of human immunodeficiency virus (HIV) and has markedly improved the disease burden and life expectancy of people living with HIV. HIV enters the central nervous system (CNS) early in the course of infection, establishes latency, and produces a pro-inflammatory milieu that may affect cognitive functions, even in the cART era. Whereas severe forms of neurocognitive impairment (NCI) such as HIV-associated dementia have declined over the last decades, milder forms have become more prevalent, are commonly multifactorial, and are associated with comorbidity burdens, mental health, cART neurotoxicity, and ageing. Since 2007, the Frascati criteria have been used to characterize and classify HIV-associated neurocognitive disorders (HAND) into three stages, namely asymptomatic neurocognitive impairment (ANI), mild neurocognitive disorder (MND), and HIV-associated dementia (HAD). These criteria are based on a comprehensive neuropsychological assessment that presupposes the availability of validated, demographically adjusted, and normative population data. Novel neuroimaging modalities and biomarkers have been proposed in order to complement NCI assessments, elucidate neuropathogenic mechanisms, and support HIV-associated NCI diagnosis, monitoring, and prognosis. By integrating neuropsychological assessments with biomarkers and neuroimaging into a holistic care approach, clinicians can enhance diagnostic accuracy, prognosis, and patient outcomes. This review interrogates the value of these modes of assessment and proposes a unified approach to NCI diagnosis.

Cognitive impairment and neurocognitive profiles among people living with HIV and HIV-negative individuals older over 50 years: a comparison of IHDS, MMSE and MoCA

We aimed to examine the l differences in the assessment of neurocognitive impairment (NCI) using cognitive screening tools between PLWH and HIV-negative individuals and further compare the neurocognitive profiles between the two groups. This was baseline evaluation of Pudong HIV Aging Cohort, including 465 people living with HIV (PLWH) and 465 HIV-negative individuals aged over 50 years matched by age (± 3 years), sex and education. NCI was assessed using the Chinese version of Mini-mental State Examination (MMSE), the International HIV Dementia Scale (IHDS) and Beijing version of Montreal Cognitive Assessment (MoCA). In total, 258 (55.5%), 91 (19.6%), 273 (58.7%) of PLWH were classified as having NCI by the IHDS, MMSE and MoCA, compared to 90 (19.4%), 25 (5.4%), 135 (29.0%) of HIV-negative individuals, respectively (p < 0.05); such associations remained significant in multivariable analysis. PLWH showed a larger overlap of NCI detected by IHDS, MMSE, and MoCA. IHDS and MoCA detected almost all of the NCI detected by MMSE. IHDS-motor and psychomotor speeds and MoCA-executive function showed the greatest disparities between two groups. In multivariable analysis, older age and more depressive symptoms were positively associated with NCI regardless of the screening tools or HIV serostatus. PLWH over 50 years old display a higher prevalence of NCI and distinct neurocognitive profiles compared to HIV-negative individuals, despite viral suppression. Given the more considerable overlap in NCI classification in PLWH, it is advisable to choose one screening tool such as IHDS or MoCA to identify those potentially having NCI and then refer to more comprehensive neuropsychological assessment.

Accelerated aging in people living with HIV: The neuroimmune feedback model

People living with HIV (PLWH) experience earlier onset of aging-related comorbidities compared to their counterparts without HIV. This paper lays out a theoretical model to explain why PLWH experience accelerated aging. Briefly, the model is structured as follows. PLWH experience disproportionately heavy burdens of psychosocial stress across the life course. This psychosocial stress increases risks for depressive symptoms and problematic substance use. Depressive symptoms and problematic substance use interfere with long-term adherence to antiretroviral therapy (ART). Lower ART adherence, in turn, exacerbates the elevated systemic inflammation stemming from HIV infection. This inflammation increases risks for aging-related comorbidities. Systemic inflammation also reduces connectivity in the brain's central executive network (CEN), a large-scale brain network that is critical for coping with stressful circumstances. This reduced capacity for coping with stress leads to further increases in depressive symptoms and problematic substance use. Together, these changes form a neuroimmune feedback loop that amplifies the impact of psychosocial stress on aging-related comorbidities. In this paper, I review the existing evidence relevant to this model and highlight directions for future research.

Social support network factors associated with verbal fluency among vulnerable persons living with HIV

Vulnerable persons living with HIV (PLWH) are at high risk of cognitive impairment and challenges accessing quality social support in later life. Impaired verbal fluency (VF), a cognitive domain linked to HIV, could impede social support associated with health and well-being for already vulnerable PLWH. We examined the structure of social support, using latent class analysis, and the associations among quantity, specific forms and quality of social support and VF among PLWH. Participants enrolled in the BEACON study (n = 383) completed the Controlled Oral Word Association test (COWAT) and a social support network inventory. Latent class analysis with count variables was used to determine the number of classes of PLWH based on their social network characteristics. The majority of PLWH were male (61.4%) and African American (85.9%). Two distinct latent classes, with a major distinction in the number of network members who were female, knew participants' HIV status and HIV medication usage. Fewer support network members (β = -.13, p < 0.01), greater negative interactions (β = -.16, p < 0.01), and less positive interactions with network members (β = .15, p < 0.05) were significantly associated with lower COWAT scores. Comprehensive screening of high-risk PLWH and early intervention with those with cognitive impairment are important for addressing social support needs.

Common antiretroviral combinations are associated with somatic depressive symptoms in women with HIV

OBJECTIVE

While modern antiretroviral therapy (ART) is highly effective and safe, depressive symptoms have been associated with certain ART drugs. We examined the association between common ART regimens and depressive symptoms in women with HIV (WWH) with a focus on somatic vs. nonsomatic symptoms.

DESIGN

Analysis of longitudinal data from the Women's Interagency HIV Study.

METHODS

Participants were classified into three groups based on the frequency of positive depression screening (CES-D ≥16): chronic depression (≥50% of visits since study enrollment), infrequent depression (<50% of visits), and never depressed (no visits). Novel Bayesian machine learning methods building upon a subset-tree kernel approach were developed to estimate the combined effects of ART regimens on depressive symptoms in each group after covariate adjustment.

RESULTS

The analysis included 1538 WWH who participated in 12 924 (mean = 8.4) visits. The mean age was 49.9 years, 72% were Black, and 14% Hispanic. In the chronic depression group, combinations including tenofovir alafenamide and cobicistat-boosted elvitegravir and/or darunavir were associated with greater somatic symptoms of depression, whereas those combinations containing tenofovir disoproxil fumarate and efavirenz or rilpivirine were associated with less somatic depressive symptoms. ART was not associated with somatic symptoms in the infrequent depression or never depressed groups. ART regimens were not associated with nonsomatic symptoms in any group.

CONCLUSIONS

Specific ART combinations are associated with somatic depressive symptoms in WWH with chronic depression. Future studies should consider specific depressive symptoms domains as well as complete drug combinations when assessing the relationship between ART and depression.

Latent Profile Analysis of Cognitive Performance and Depressive Symptoms Among People with HIV

Depression and cognitive impairment are prevalent conditions among people with HIV (PWH), likely attributable to shared causes and common risk factors. Identifying subtypes of PWH with similar patterns of neurocognitive impairment (NCI) and depressive symptoms may inform development of patient-centered interventions that target-specific profiles. This study aimed to (1) classify PWH based on patterns of domain-specific NCI and depression; and (2) determine the relationship between latent class membership and pertinent clinical characteristics. PWH (N = 580, 86.2% male, 57.1% non-Hispanic White, 69.2% unemployed) completed a comprehensive neuropsychological test battery assessing global and domain-specific cognition. Domain-specific NCI was classified as deficit score >0.5. Participants completed the Beck Depression Inventory-II (BDI-II), and domain-specific BDI-II scores reflecting cognitive, affective, and somatic symptoms were computed. Latent profile analysis (LPA) was used to determine latent subgroups of NCI and depression. The optimal LPA solution consisted of five classes: minimal NCI and minimal depression (Class 1), amnestic and minimal depression (Class 2), severe multi-domain NCI and moderate depression (somatic and affective; Class 3), mild NCI and mild depression (Class 4), and moderate multi-domain NCI and severe depression (Class 5). Despite similar levels of functional impairment, Class 5 had a significant psychiatric profile, whereas Class 3 had a complex medical profile (i.e., higher frailty index, higher medications, greater proportion of AIDS diagnosis). In contrast, Class 1 had the lowest medication use and frailty index, with similar HIV disease characteristics to Classes 3 and 5. Our results suggest there are multiple pathways to cognitive and functional impairment among PWH with co-occurring depression and cognitive impairment, and these groups may respond differently to interventions. Of note, our sample was majority non-Hispanic White and male, which is nonrepresentative of the US population of PWH. Future interventions should consider a more integrated, person-centered approach that addresses cognitive and emotional health to optimize health outcomes in PWH.

Identifying and distinguishing cognitive profiles among virally suppressed people with HIV

OBJECTIVE

Cognitive deficits are common among people with HIV (PWH), even when virally suppressed. We identified cognitive profiles among virally suppressed PWH and determined how sociodemographic, clinical/behavioral, and HIV disease characteristics distinguish profile membership.

METHOD

Participants included 704 virally suppressed PWH (Mage = 43.9 [SD = 10.2], 88% male, 58.9% non-Hispanic White) from the HIV Neurobehavioral Research Program. Demographically adjusted T scores were derived from a neuropsychological evaluation comprised of 13 tests. We implemented a pipeline involving dimension reduction and clustering to identify profiles of cognitive performance. Random forest models on a 70/30 training/testing set with internal cross-validation were used to identify sociodemographic, clinical/behavioral, and HIV disease correlates of profile membership.

RESULTS

Six cognitive profiles were identified: (a) "unimpaired" (19.9%); (b) weakness in verbal learning and memory (15.5%); (c) weakness in executive function and learning (25.8%); (d) weakness in motor, processing speed, and executive function (8.1%); (e) impaired learning and recall with weak-to-impaired motor, processing speed, and executive function (13.1%); (f) global deficits (17.6%). The most discriminative sociodemographic, clinical/behavioral, and HIV disease characteristics varied by profile with self-reported mood symptoms and cognitive/functional difficulties (e.g., language/communication, memory, and overall everyday function complaints) most consistently associated with profile membership.

CONCLUSIONS

Cognitive profiles and their associated factors among PWH are heterogeneous, but learning/memory deficits were most common and self-reported mood, and cognitive/functional difficulties were most consistently related to profile membership. This heterogeneity in cognitive profiles and their correlates in PWH suggests that differing mechanisms contribute to cognitive deficits and, thus, underscores the need for personalized risk reduction and therapeutic strategies among PWH.

The Social, Mental, and Physical Health Impacts of the COVID-19 Pandemic on People With HIV: Protocol of an Observational International Multisite Study

ABSTRACT

As the COVID-19 pandemic spread across the world, immunocompromised individuals such as people with HIV (PWH) may have faced a disproportionate impact on their health and HIV outcomes, both from COVID-19 and from the strategies enacted to contain it. Based on the SPIRIT guidelines, we describe the protocol for an international multisite observational study being conducted by The International Nursing Network for HIV Research, with the Coordinating Center based at the University of California, San Francisco (UCSF) School of Nursing. Site Principal Investigators implement a standardized protocol to recruit PWH to complete the study online or in-person. Questions address demographics; HIV continuum of care indicators; mental and social health; COVID-19 and vaccination knowledge, attitudes, behaviors, and fears; and overall outcomes. Results of this study will contribute to knowledge that can inform responses to future public health crises to minimize their impacts on vulnerable populations such as PWH.

Update on Central Nervous System Effects of the Intersection of HIV-1 and SARS-CoV-2

PURPOSE OF REVIEW

Research has shown myriad neurologic and mental health manifestations during the acute and subsequent stages of COVID-19 in people with HIV (PWH). This review summarizes the updates on central nervous system (CNS) outcomes following SARS-CoV-2 infection in PWH and highlight the existing knowledge gaps in this area.

RECENT FINDINGS

Studies leveraging electronic record systems have highlighted the excess risk of developing acute and lingering neurological complications of COVID-19 in PWH compared to people without HIV (PWoH). However, there is a notable scarcity of neuroimaging as well as blood and cerebrospinal fluid (CSF) marker studies that can confirm the potential synergy between these two infections, particularly in PWH receiving suppressive antiretroviral therapy. Considering the unclear potential interaction between SARS-CoV-2 and HIV, clinicians should remain vigilant regarding new-onset or worsening neurological symptoms in PWH following COVID-19, as they could be linked to either infection.

The adolescent HIV executive function and drumming (AHEAD) study, a feasibility trial of a group drumming intervention amongst adolescents with HIV

AHEAD feasibility trial assessed the feasibility and acceptability of an 8-session group drumming programme aiming to improve executive function, depression and anxiety symptoms, and perceived social support in adolescents living with HIV in a rural low-income South African setting. Sixty-eight 12- to 19-year-old adolescents participated. They were individually randomised. The intervention arm (n = 34) received weekly hour-long group drumming sessions. Controls (n = 34) received no intervention. Feasibility and acceptability were assessed using rates of: enrolment; retention; attendance; logistical problems; adolescent-reported acceptability. Secondary measures included: five Oxford Cognitive Screen-Executive Function (OCS-EF) tasks; two Rapid Assessment of Cognitive and Emotional Regulation (RACER) tasks; the Self-Reporting Questionnaire-20 (SRQ-20) measuring depression and anxiety symptoms; the Multidimensional Scale of Perceived Social Support (MSPSS). All feasibility criteria were within green progression limits. Enrolment, retention, and acceptability were high. There was a positive effect on adolescent depressed mood with signal for a working memory effect. There were no significant effects on executive function or socio-emotional scales. Qualitative findings suggested socio-emotional benefits including: group belonging; decreased internalised stigma; improved mood; decreased anxiety. Group drumming is a feasible and acceptable intervention amongst adolescents living with HIV in rural South Africa. A full-scale trial is recommended.

Trajectories of depressive symptoms in young and middle-aged men who have sex with men with new HIV-diagnosis: a 1-year prospective cohort study in Beijing, China

Introduction

Due to the sexual orientation and HIV diagnosis, young and middle-aged men who have sex with men (MSM) with new HIV-diagnosis may experience more depressive syndromes and face greater psychological stress. The study explored trajectories of depressive symptoms of young and middle-aged MSM within 1 year after new HIV-diagnosis and analyze the related factors.

Methods

From January 2021 to March 2021, 372 young and middle-aged MSM who were newly diagnosed as HIV-infection were recruited in two hospitals in Beijing. Self-rating Depression Scale was used to measure the participants' depressive symptom in 1st month, 3rd month, 6th month, 9th month and 12th month after HIV diagnosis. The latent class growth model was used to identify trajectories of the participants' depressive symptoms. Multinomial logistic regression was used to analyse factors related with the trajectories.

Results

Three hundred and twenty-eight young and middle-aged MSM with new HIV-diagnosis completed the research. Depressive symptom in 328 young and middle-aged MSM was divided into three latent categories: non-depression group (56.4%), chronic-mild depression group (28.1%), and persistent moderate-severe depression group (15.5%). The participants assessed as non-depression (non-depression group) or mild depression (chronic-mild depression group) at the baseline were in a non-depression state or had a downward trend within one-year, and the participants assessed as moderate and severe depression (persistent moderate-severe depression group) at the time of diagnosis were in a depression state continuously within 1-year. Multinomial logistic regression analysis showed that, compared with the non-depression group, monthly income of 5,000 ~ 10,000 RMB (equal to 690 ~ 1,380 USD) was the risk factor for the chronic-mild depression group, and self-rating status being fair/good and self-disclosure of HIV infection were protective factors for the persistent moderate-severe depression group while HIV-related symptoms was the risk factor.

Conclusion

Depressive symptoms in young and middle-aged MSM is divided into three latent categories. Extra care must be given to young and middle-aged MSM assessed as moderate or severe depression at the time of HIV-diagnosis, especially to those who had poor self-rating health status, did not tell others about their HIV-infection and experienced HIV-related symptoms.

Sex differences in cognitive function among people with HIV-1 clade C infection in Northern India

Human immunodeficiency virus-1 (HIV-1) clade C is the most prevalent form of HIV-1 comprising nearly 46% of global infections and is the dominant subtype in India. Despite its predominance, the impact of HIV-1 clade C infection on cognitive function has been understudied in comparison with other subtypes, notably clade B, which is primarily found in Europe and North America. Few studies have assessed cognitive impairment in antiretroviral therapy (ART) naïve men and women with HIV-1 clade C infection. In this study conducted in Northern India, differences in neuropsychological functioning were compared between 109 participants (70 men, 39 women) with untreated HIV-1 clade C infection and 110 demographically matched healthy controls (74 men, 36 women). A comprehensive neuropsychological battery was used to examine depression, self-assessment of functioning, and cognitive performance in six domains of functioning. Group differences were assessed by HIV-1 status and sex, controlling for age and education. Results indicated that cognitive deficits were substantially greater among male participants with HIV-1 clade C compared to male controls in all domains of cognitive functioning; in contrast, women with HIV-1 clade C had only minor deficits compared to healthy female participants. In addition, a larger proportion of men with HIV-1 clade C exhibited high levels of depression than women with HIV-1 clade C. These findings suggest that untreated HIV-1 clade C infection in men can have debilitating effects on neuropsychological function and depression, and stress the importance of facilitating rapid access to treatment to reduce the impact of HIV-1 infection.

Antiretroviral Therapy Intensification for Neurocognitive Impairment in Human Immunodeficiency Virus

BACKGROUND

Neurocognitive impairment (NCI) in people with HIV (PWH) on antiretroviral therapy (ART) is common and may result from persistent HIV replication in the central nervous system.

METHODS

A5324 was a randomized, double-blind, placebo-controlled, 96-week trial of ART intensification with dolutegravir (DTG) + MVC, DTG + Placebo, or Dual - Placebo in PWH with plasma HIV RNA <50 copies/mL on ART and NCI. The primary outcome was the change on the normalized total z score (ie, the mean of individual NC test z scores) at week 48.

RESULTS

Of 357 screened, 191 enrolled: 71% male, 51% Black race, 22% Hispanic ethnicity; mean age 52 years; mean CD4+ T-cells 681 cells/µL. Most (65%) had symptomatic HIV-associated NC disorder. Study drug was discontinued due to an adverse event in 15 (8%) and did not differ between arms (P = .17). Total z score, depressive symptoms, and daily functioning improved over time in all arms with no significant differences between them at week 48 or later. Adjusting for age, sex, race, study site, efavirenz use, or baseline z score did not alter the results. Body mass index modestly increased over 96 weeks (mean increase 0.32 kg/m2, P = .006) and did not differ between arms (P > .10).

CONCLUSIONS

This is the largest, randomized, placebo-controlled trial of ART intensification for NCI in PWH. The findings do not support empiric ART intensification as a treatment for NCI in PWH on suppressive ART. They also do not support that DTG adversely affects cognition, mood, or weight.

Cognitive concerns are a risk factor for mortality in people with HIV and coronavirus disease 2019

BACKGROUND

Data supporting dementia as a risk factor for coronavirus disease 2019 (COVID-19) mortality relied on ICD-10 codes, yet nearly 40% of individuals with probable dementia lack a formal diagnosis. Dementia coding is not well established for people with HIV (PWH), and its reliance may affect risk assessment.

METHODS

This retrospective cohort analysis of PWH with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) PCR positivity includes comparisons to people without HIV (PWoH), matched by age, sex, race, and zipcode. Primary exposures were dementia diagnosis, by International Classification of Diseases (ICD)-10 codes, and cognitive concerns, defined as possible cognitive impairment up to 12 months before COVID-19 diagnosis after clinical review of notes from the electronic health record. Logistic regression models assessed the effect of dementia and cognitive concerns on odds of death [odds ratio (OR); 95% CI (95% confidence interval)]; models adjusted for VACS Index 2.0.

RESULTS

Sixty-four PWH were identified out of 14 129 patients with SARS-CoV-2 infection and matched to 463 PWoH. Compared with PWoH, PWH had a higher prevalence of dementia (15.6% vs. 6%, P  = 0.01) and cognitive concerns (21.9% vs. 15.8%, P  = 0.04). Death was more frequent in PWH ( P  < 0.01). Adjusted for VACS Index 2.0, dementia [2.4 (1.0-5.8), P  = 0.05] and cognitive concerns [2.4 (1.1-5.3), P  = 0.03] were associated with increased odds of death. In PWH, the association between cognitive concern and death trended towards statistical significance [3.92 (0.81-20.19), P  = 0.09]; there was no association with dementia.

CONCLUSION

Cognitive status assessments are important for care in COVID-19, especially among PWH. Larger studies should validate findings and determine long-term COVID-19 consequences in PWH with preexisting cognitive deficits.

Cognitive Performance, as well as Depression, Alcohol Use, and Gender, predict Anti-Retroviral Therapy Adherence in a South African Cohort of People with HIV and Comorbid Major Depressive Disorder

Depression and cognitive impairment, which commonly coexist in people with HIV (PWH), have been identified as potential barriers to optimal antiretroviral therapy (ART) adherence. We investigated associations between cognitive performance, depression (as well as other sociodemographic, psychosocial and psychiatric variables) and ART adherence in a South African cohort of PWH with comorbid major depressive disorder (MDD). Cognitive performance and ART adherence were assessed at two time points 8 months apart (Nbaseline = 105, Nfollow-up = 81). Adherence was indicated by self-report, objective measures (Wisepill usage and plasma tenofovir-diphosphate levels), and HIV viral suppression. Mixed-effects regression models examined associations across both time points. Univariate models detected no significant associations between cognitive performance (globally and within-domain) and ART adherence. Multivariate modelling showed increased depression severity (β = - 0.54, p < 0.001) and problematic alcohol use (β = 0.73, p = 0.015) were associated with worse adherence as measured subjectively. Being female (OR 0.27, p = 0.048) and having better global cognitive performance (OR 1.83, p = 0.043) were associated with better adherence as indicated by viral suppression. This study identifies poor global cognitive performance, as well as depression and problematic alcohol use, as potential barriers to optimal ART adherence in PWH and comorbid MDD. Hence, clinicians could consider assessing for cognitive deficits, depression, and problematic alcohol use, and should endeavour to provide the appropriate support so as to improve adherence.

Cerebrospinal fluid levels of 5-HIAA and dopamine in people with HIV and depression

Depression is a common illness in people with HIV (PWH) and is associated with substantial morbidity and mortality. The mechanisms that underpin depression in PWH remain incompletely elucidated, and more research is therefore needed to develop effective treatments. One hypothesis is that neurotransmitter levels may be altered. These levels could be influenced by the chronic inflammation and viral persistence that occurs in PWH. We examined a panel of cerebrospinal fluid (CSF) neurotransmitters in PWH on suppressive antiretroviral therapy (ART), many of whom had a current depression diagnosis. CSF monoamine neurotransmitters and their metabolites were measured from participants in studies at the Emory Center for AIDS Research (CFAR). Only participants on stable ART with suppressed HIV RNA from both plasma and CSF were analyzed. Neurotransmitter levels were measured with high-performance liquid chromatography (HPLC). Neurotransmitters and their metabolites included dopamine (DA), homovanillic acid (HVA, a major metabolite of dopamine), serotonin (5-HT), 5-hydroxyindole-3-acetic acid (5-HIAA, a major metabolite of serotonin), and 4-hydroxy-3-methoxyphenylglycol (MHPG, a major metabolite of norepinephrine). Multivariable logistic regression was used to evaluate factors associated with depression. There were 79 PWH with plasma and CSF HIV RNA levels < 200 copies/mL at the time of the visit, and 25 (31.6%) carried a current diagnosis of depression. Participants with depression were significantly older (median age 53 years versus 47 years, P = 0.014) and were significantly less likely to be African American (48.0% versus 77.8%, P = 0.008). Participants with depression had significantly lower dopamine levels (median 0.49 ng/mL versus 0.62 ng/mL, P = 0.03) and significantly lower 5-HIAA levels (median 12.57 ng/mL versus 15.41 ng/mL, P = 0.015). Dopamine and 5-HIAA were highly correlated. In the multivariable logistic regression models, lower 5-HIAA was significantly associated with the depression diagnosis when accounting for other significant demographic factors. The associations between lower 5-HIAA, lower dopamine, and depression in PWH suggest that altered neurotransmission may contribute to these comorbid conditions. However, the effects of antidepressants on neurotransmitters cannot be ruled out as a factor in the 5-HIAA results.

Cognitive impairment in people living with HIV: consensus recommendations for a new approach

Current approaches to classifying cognitive impairment in people living with HIV can overestimate disease burden and lead to ambiguity around disease mechanisms. The 2007 criteria for HIV-associated neurocognitive disorders (HAND), sometimes called the Frascati criteria, can falsely classify over 20% of cognitively healthy individuals as having cognitive impairment. Minimum criteria for HAND are met on the basis of performance on cognitive tests alone, which might not be appropriate for populations with diverse educational and socioeconomic backgrounds. Imprecise phenotyping of cognitive impairment can limit mechanistic research, biomarker discovery and treatment trials. Importantly, overestimation of cognitive impairment carries the risk of creating fear among people living with HIV and worsening stigma and discrimination towards these individuals. To address this issue, we established the International HIV-Cognition Working Group, which is globally representative and involves the community of people living with HIV. We reached consensus on six recommendations towards a new approach for diagnosis and classification of cognitive impairment in people living with HIV, intended to focus discussion and debate going forward. We propose the conceptual separation of HIV-associated brain injury - including active or pretreatment legacy damage - from other causes of brain injury occurring in people living with HIV. We suggest moving away from a quantitative neuropsychological approach towards an emphasis on clinical context. Our recommendations are intended to better represent the changing profile of cognitive impairment in people living with HIV in diverse global settings and to provide a clearer framework of classification for clinical management and research studies.

Association between depression and HIV infection vulnerable populations in United States adults: a cross-sectional analysis of NHANES from 1999 to 2018

Background

Although the government has made a commitment to advance education on HIV disclosure, depression continues to play a significant role in whether people living with HIV (PLWH) choose to disclose their HIV status to families or friends. Vulnerable populations who are at risk of contracting HIV may also be more susceptible to mental illness. However, there is a limited understanding of the association between depression and vulnerable populations affects by HIV among United States adults. We aimed to explore the incidence of depression in the HIV infection vulnerable populations and assessed the association between the HIV infection vulnerable populations and depression.

Methods

We analyzed the most current statistics from the National Health and Nutrition Examination Survey (NHANES) that included 16,584 participants aged 18 years or older between 1999 and 2018. The Patient Health Questionnaire-9 (PHQ-9) was used to evaluate symptoms of depressive disorder. Demographic characteristics were compared between the HIV infection vulnerable groups and HIV infection low-risk groups. Multivariable logistic regression analysis was also carried out to evaluate the odds rate and association between the HIV infection vulnerable populations and depression.

Results

Based on the most recent statistics from NHANES, HIV infection vulnerable populations were male, younger, less married or living together, non-Hispanic White people, lower income, and lower body mass index (BMI), with higher levels of cigarette smoking, alcohol drinking, a higher prevalence of depression, lower prevalence of hypertension and diabetes mellitus (DM; p < 0.05). Additionally, individuals with severe depression had a higher prevalence of cardiovascular disease (CVD), hypertension, DM, chronic kidney disease (CKD), and a higher proportion of HIV infection vulnerable populations and less married or living together (p < 0.01). Finally, the odds of depression from the logistic regression were significantly increased in HIV infection vulnerable groups (p < 0.01).

Conclusion

Depression might be associated with HIV infection vulnerable populations in the United States adults. More research is needed to evaluate the association between HIV infection vulnerable populations and depression and explore their causal associations. In addition, prevention efforts focusing on HIV disclosure and HIV infection vulnerable populations in the United States should address common co-prevalent depression to reduce new HIV infections.

Analysis of Factors Influencing Depression in Elderly People Living with HIV/AIDS Based on Structural Equation Model: A Cross-Sectional Study in Guangxi, China

Purpose

The purpose of our study is to understand the current status of depression and medical social support in elderly HIV/AIDS, as well as the role of social support on depression, so as to provide a certain reference for reducing the occurrence of depression in the population.

Methods

A total of 115 participants with PLWHA (people living with HIV/AIDS) aged 50 years or older were collected in Guilin from December 2021 to July 2022. Depression and medical social support were assessed using the Center for Streaming Depression Scale (CES-D) and the Medical Social Support Scale (MOS-SSS). The structural equation model was used to examine the relationship between medical social support and depression.

Results

Sixty-one of 115 participants developed depressive symptoms with a prevalence of 53.0%. The results of univariate analysis showed that ethnicity, health status, mean monthly income, antiviral treatment status, and medical social support influenced PLWHA depression (P<0.05). Simple linear regression showed that health status (95% CI: -9.901~-2.635), and antiviral treatment status (95% CI: -12.969~-3.394) influent depression (P<0.05). There were associations between total medical social support, practical support dimension, message and emotional support dimension, social interactive cooperation dimension, emotional support dimension and depression (unadjusted and adjusted for contextual factors) (P < 0.05). Using multiple linear regression analyses, we found that medical-social support was negatively associated with depression with a standardized effect value of -0.223. PLWHA with higher medical social support had lower prevalence of depression.

Conclusion

The results indicate that the prevalence of depression among HIV/AIDS patients in Guilin is high. So the joint efforts of individuals, families, and society are needed to improve the physical and mental health of the PLWHA.

Association between personality and cognitive performance in middle-aged and older adults with human immunodeficiency virus (HIV)

BACKGROUND

Nearly half of adults with human immunodeficiency virus (HIV) experience HIV-Associated Neurocognitive Disorder (HAND), characterized by cognitive impairments in two or more cognitive domains, which can interfere with everyday functioning. Many factors are thought to influence such cognitive impairments in adults with HIV; one factor seldom examined is personality.

OBJECTIVE

This study investigated the association between five major dimensions of personality (openness, conscientiousness, extraversion, agreeableness, and neuroticism) and cognitive function in older adults with HIV.

METHODS

In this cross-sectional study, a secondary data analysis was conducted on 261 HIV + participants. Participants completed a norm-based cognitive battery covering seven cognitive domains, which yielded the following indices: global cognitive impairment, and global and domain-specific T-scores. The Big Five Inventory was used to assess personality traits.

RESULTS

Higher openness, conscientiousness, and agreeableness were associated with better performance on individual cognitive domains while agreeableness and openness were also positively associated with global cognitive T-scores (p < .01). Only openness significantly predicted global cognition when adjusting for covariates (p < .01).

DISCUSSION

Openness was associated with better global cognitive function in persons with HIV. This study provides a basis for further investigation of potential mechanisms for the association between personality and cognition in people with HIV in order to ultimately inform intervention strategies.

Social Support, Internalized HIV Stigma, Resilience and Depression Among People Living with HIV: A Moderated Mediation Analysis

Internalized HIV stigma has been associated with depression among people living with HIV (PLWH). However, it is still unclear whether resilience would mediate the association between internalized HIV stigma and depression and how this indirect effect would be moderated by social support. Data were collected from 402 PLWH in South Carolina using a cross-sectional survey. Data were fitted using a path model that specified the extent to which internalized HIV stigma and depression were related through resilience and how this effect was moderated by social support. Sociodemographic characteristics were included in the model as covariates. The indirect effect of internalized HIV stigma on depression through resilience was statistically significant for high social support but not for low social support. To mitigate negative impacts of internalized HIV stigma on mental health of PLWH, intervention efforts should integrate multilevel components for promoting both resilience and social support.
