Arch Gerontol Geriatr 2023; 109:104950. [PMID: 36739679 DOI: 10.1016/j.archger.2023.104950] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2022] [Revised: 01/24/2023] [Accepted: 01/27/2023] [Indexed: 01/30/2023]
Abstract
BACKGROUND Despite the progress made in managing HIV, the mortality trends among older adults in the US remains understudied. The lack of evidence in this demographic hampers the ability to implement evidence-based interventions. Our aim is to analyze the trends in HIV-related mortality among US citizens aged 65 years and above by demographic characteristics such as age, gender, race/ethnicity, and census region. METHODS We abstracted national mortality data from the underlying cause of death files in the CDC WONDER database. The ICD-10 Codes- B20-B24 were used to identify HIV deaths among US older adults from 1999 to 2020. Trends in age-adjusted mortality rate (AAMR) were assessed using a five-year simple moving average and Joinpoint analysis. Results were expressed as annual percentage changes (APC), average annual percentage changes, and 95% confidence intervals (CI). RESULTS Between 1999 and 2020, a total of 15,694 older adults died from HIV in the US (AAMR= 1.7 per 100,000; 95% CI: 1.6 - 1.7). Overall mortality trends increased at an annual rate of 1.5% (95% CI: 1.2, 1.8) from 1999 through 2020. The trends increased among Non-Hispanic Whites, stabilized among Non-Hispanic Blacks, and decreased among Hispanics from 1999 to 2020. Further, the trends increased consistently across categories of age (65 to 74 years; 75 to 84 years), sex, and census region. CONCLUSIONS HIV mortality among older adults in the US has risen overall from 1999 to 2020, but with varying trends by race and ethnicity. This highlights the need for enhanced public health surveillance to better understand the scope of HIV mortality among older adults and identify high-risk demographic and regional subgroups for targeted interventions. Improving timely diagnosis, managing comorbidities, and stigma surrounding HIV among older adults are crucial to reducing HIV mortality in this population.

Rationale and design of the Anal HPV, HIV and Aging (AHHA) study: Protocol for a prospective study of anal HPV infection and HSIL among men who have sex (MSM) or trans women living with and without HIV, ages 50 and older. FRONTIERS IN EPIDEMIOLOGY 2022; 2:992718.

Abstract
Introduction More than half of people living with HIV in the US are 50+ years old. Despite the benefits of antiretroviral therapy, older individuals with HIV are at higher risk for illnesses than their HIV-negative counterparts. Anal cancer, anal high-grade squamous intraepithelial lesions (HSIL), and anal HPV-16 infection occur most frequently among men who have sex with men living with HIV (MSMLWH). Men aged 60+ are 3-fold more likely to be diagnosed with anal cancer compared with younger men. Despite the increasing risk of anal cancer with age and HIV, little is known about the relationships among aging, HPV infection, HSIL and HIV. Methods and analysis The Anal HPV, HIV, and Aging (AHHA) Study is a two-stage project to evaluate the relationships among anal HPV infection, HSIL, HIV infection, and biomarkers of biological aging in MSM or trans women over the age of 50 years. Stage 1 will estimate the cross-sectional prevalence of both anal HPV infection and HSIL, based on outcomes of anal HPV DNA testing, and high-resolution anoscopy with biopsy. We will also study associations with study outcomes and serological biomarkers of inflammation (interleukin-6, C-reactive protein, D-dimer) and with the Veterans Aging Cohort Study Index and the Fried Frailty Phenotype using multivariable models. Participants living with HIV (n = 150) and HIV-negative participants (n = 150) will be enrolled. The 3-year Stage 2 longitudinal sample restricted to HSIL-negative and anal HPV-16 DNA-negative participants will estimate the 3-year incidence of both anal HSIL and anal HPV, stratified by HIV status through Cox proportional hazards regression. The effect of biomarkers of inflammation and markers of aging on study outcomes will be evaluated through multivariable repeated measures models stratified by HIV status. Ethics and dissemination This protocol was approved by the University of California, San Francisco Institutional Review Board (IRB: 16-18966). Results will be disseminated through presentations at national/international scientific conferences and publication in peer-reviewed journals.

Abstract
BACKGROUND Aging in people with HIV is associated with increased risk of developing synergistic conditions such as neurocognitive impairment, polypharmacy, and falls. We assessed associations between polypharmacy (use of 5 or more non-ART medications), use of neurocognitive adverse effects (NCAE) medications, and odds of falls in women with HIV (WWH) and without HIV (HIV-). METHODS Self-reported falls and medication use data were contributed semiannually by 1872 (1315 WWH and 557 HIV-) Women's Interagency HIV Study participants between 2014 and 2016. Polypharmacy and NCAE medication use were evaluated separately and jointly in multivariable models to assess their independent contributions to single and multiple falls risk. RESULTS The proportion of women who reported any fall was similar by HIV status (19%). WWH reported both greater polypharmacy (51% vs. 41%; P < 0.001) and NCAE medication use (44% vs. 37%; P = 0.01) than HIV- women. Polypharmacy conferred elevated odds of single fall [adjusted odds ratio (aOR) 1.67, 95% CI: 1.36 to 2.06; P < 0.001] and multiple falls (aOR 2.31, 95% CI: 1.83 to 2.93; P < 0.001); the results for NCAE medications and falls were similar. Both polypharmacy and number of NCAE medications remained strongly and independently associated with falls in multivariable models adjusted for HIV serostatus, study site, sociodemographics, clinical characteristics, and substance use. CONCLUSIONS Polypharmacy and NCAE medication use were greater among WWH compared with HIV-, and both were independently and incrementally related to falls. Deprescribing and avoidance of medications with NCAEs may be an important consideration for reducing fall risk among WWH and sociodemographically similar women without HIV.

Abstract
OBJECTIVE This study evaluated body mass index (BMI) and weight changes in people living with human immunodeficiency virus (HIV-1; PLWH) initiated on single-tablet darunavir/cobicistat/emtricitabine/tenofovir alafenamide (DRV/c/FTC/TAF) or bictegravir/FTC/TAF (BIC/FTC/TAF). METHODS Electronic medical record (EMR) data for treatment-naïve or virologically suppressed adults with HIV-1 who initiated treatment with DRV/c/FTC/TAF or BIC/FTC/TAF (index date) were obtained from Decision Resources Group's EMRs (17 July 2017-1 March 2020). Inverse probability of treatment weighting was used to account for differences in baseline characteristics between the two cohorts. BMI and weight changes from pre-index to 3, 6, 9 and 12 months following the index date were compared using weighted mean differences (MDs). The time until an increase in BMI or weight ≥5% or ≥10% was compared using weighted hazard ratios (HRs). RESULTS The weighted DRV/c/FTC/TAF and BIC/FTC/TAF cohorts comprised 1116 and 1134 PLWH, respectively (mean age = ∼49 years, females: ∼28%). Larger increases in BMI and weight from pre-index to each post-index time point were observed in PLWH initiating BIC/FTC/TAF vs DRV/c/FTC/TAF (12 months: MD in BMI = 1.23 kg/m2, p < .001; MD in weight = 2.84 kg [6.26 lbs], p = .008). PLWH receiving BIC/FTC/TAF were significantly more likely to experience weight gain ≥5% (HR = 1.76, p = .004) and ≥10% (HR = 2.01, p = .020), and BMI increase ≥5% (HR = 1.77, p = .004) and ≥10% (HR = 1.76, p = .044) than those receiving DRV/c/FTC/TAF. CONCLUSIONS BIC/FTC/TAF was associated with greater BMI and weight increases compared to DRV/c/FTC/TAF. Weight gain and its sequelae may add to the clinical burden of PLWH and should be considered among other factors when selecting antiretroviral single-tablet regimens.

Abstract
The purpose of this study was to identify factors associated with HIV-associated neurocognitive disorder (HAND) and symptoms of anxiety and depression in HIV+ Brazilian elderly on antiretroviral treatments. The study included 112 HIV+ elderly who completed a questionnaire, tests for cognitive screening, attention, problem solving, processing speed, visual perception, memory, and anxiety and depression scales. The results showed presence of HAND (89.3%), pathological anxiety (48.2%) and depression (58%) in the sample. Higher income was a protective factor for HAND (OR = 0.33). Waking up well-rested (OR = 0.63) and better diet quality (OR = 0.62) reduced the chance of pathological anxiety. Higher education (OR = 0.74) and waking up well-rested (OR = 0.61) reduced the chance of depression. Being female (OR = 7.73) increased the chance of depression. It can be concluded that it is important to evaluate cognitive and emotional aspects of HIV+ elders and to consider social and educational status, diet, and sleep in interventions, paying special attention to elderly women.

Abstract
Obesity is associated with detrimental changes in cardiovascular and metabolic parameters, including blood pressure, dyslipidemia, markers of systemic inflammation, and insulin resistance. In the elderly living with the human immunodeficiency virus (EPLHIV), and being treated with antiretroviral medications, the obesity complications escalate and expose the elderly to the risk of noncommunicable diseases. Given that over 3 million EPLHIV in sub-Sahara Africa, we assessed the prevalence of obesity and its associated factors among EPLHIV in a low-resource setting.This was a cross sectional study of EPLHIV aged 50 years and older, being treated with antiretroviral medications from 2004 to 2018. HIV treatment data collected from multiple treatment sites were analyzed. Baseline characteristics of the participants were described, and multivariable relative risk model was applied to assess the associations between obesity (body mass index [BMI] ≥30 kg/m2) and the prespecified potential risk factors.Of the 134,652 in HIV cohort, 19,566 (14.5%) were EPLHIV: 12,967 (66.3%) were normal weight (18.5 ≤ BMI < 25), 4548 (23.2%) were overweight (25 ≤ BMI < 30), while 2,051 (10.5%) were obese (BMI ≥30). The average age the normal weight (57.1; standard deviation 6.6) and the obese (56.5; standard deviation 5.5) was similar. We observed that being an employed (relative risk [RR] 1.71; 95% confidence interval [CI] 1.48-2.00; P < .001), educated (RR 1.93; 95% CI 1.54-2.41; P < .001), and presence of hypertension (RR 1.78; 95% CI 1.44-2.20; P < .001), increased the risk of obesity. Also, being male (RR 0.38; 95% CI 0.33-0.44; P < .001), stages III/IV of the World Health Organization clinical stages of HIV (RR 0.58; 95% CI 0.50-0.68; P < .001), tenofovir-based regimen (RR 0.84; 95% CI 0.73-0.96, P < .001), and low CD4 count (RR 0.56; 95% CI 0.44-0.71; P < .001) were inversely associated with obesity.This study demonstrates that multiple factors are driving obesity prevalence in EPLHIV. The study provides vital information for policy-makers and HIV program implementers in implementing targeted-interventions to address obesity in EPLHIV. Its findings would assist in the implementation of a one-stop-shop model for the management of HIV and other comorbid medical conditions in EPLHIV.

Abstract
Background: People living with HIV (PLWH) are aging worldwide, and different management strategies may be required for older and younger PLWH. However, demographic characteristics, illness distribution, mortality, and independent risk factors in the PLWH population in China are not yet fully understood, especially in patients aged 50 years or older. Methods: We conducted a retrospective analysis of 4445 HIV-positive Chinese inpatients in Chongqing, China. Results: The mortality rate in patients 50 years or older (the older group) was significantly higher than that in those under 50 years (the younger group) (p < 0.001). In the younger group, independent risk factors for death included: nadir CD4+ T-cell counts <200 cells/μL, not owning medical healthcare insurance, not being on cART, injection drug use, and having one of the following comorbidities: Pneumocystis pneumonia, cryptococcal meningitis, AIDS malignancy, non-AIDS malignancy, and kidney disease. In the older group, independent predictors of death included: being urban residents, nadir CD4+ T-cell counts <200 cells/μL, not being on cART, and having comorbidities such as Pneumocystis pneumonia, hepatitis C, talaromycosis, non-AIDS malignancy, and kidney disease. Conclusions: Demographic characteristics, illness distribution, mortality, and independent risk factors for death in HIV-positive patients differ between the older group and the younger group, indicating that a changing suite of medical and allied support services may be required the for management of older PLWH.

Abstract
OBJECTIVE To determine whether domain-specific neurocognitive (NC) impairments predict falls in HIV+ compared with HIV- women. DESIGN Cross-sectional data analysis from 825 HIV+ and 392 HIV- women in the Women's Interagency HIV Study with NC testing within 2 years before falls surveys. METHODS NC impairment (T score <40) was assessed in 7 domains: executive function, psychomotor speed, attention, learning, memory, fluency, and fine motor function. For domains associated with any fall within 6 months in simple logistic regression (P < 0.05), hierarchical regression models evaluated associations between NC impairment and odds of falling, adjusting for: (1) study site and HIV, (2) demographics, (3) comorbid conditions, (4) substance use/central nervous system active medications, and HIV-specific factors. RESULTS Median age was higher in HIV+ than HIV- women (51 vs. 48 yrs); prevalence of falls was similar (19% HIV+, 16% HIV-). Overall, executive function [OR (odds ratio) = 1.82, 95% CI (confidence interval): 1.21 to 2.74; P = 0.004], psychomotor speed (OR = 1.59, 95% CI: 1.05 to 2.42, P = 0.03), and fine motor (OR 1.70, 95% CI: 1.11 to 2.61, P = 0.02) impairments were associated with greater odds of falls in fully adjusted models. In fully adjusted models, associations of executive function, psychomotor speed, and fine motor were nonsignificant among HIV+ women; conversely, among HIV- women, associations with impaired executive and fine motor functions were strengthened and remained significant. CONCLUSIONS Cognitive impairment was associated with falls among middle-aged HIV- but not HIV+ women. Additional studies should elucidate mechanisms by which domain-specific NC impairment impacts fall risk among older HIV+ and HIV- women and how different factors modify relationships between cognition and falls.

Abstract
In the United States, 4 out of 10 adults with diabetes are ≥65 years of age. The older adult with diabetes is very likely to be asymptomatic and also at higher risk of vascular disease. New concerns include new diagnosis of diabetes for older adults admitted to hospital and older adults in long-term care facilities. The pathophysiology for increased incidence of diabetes in older adults is multifactorial, but dominant features are increased likelihood of metabolic syndrome, dysfunctional insulin secretion, and peripheral insulin resistance. Society in general benefits from more cost-effective care of older adults with diabetes.

Abstract
With the advent of combined antiretroviral therapies, the face of HIV infection has changed dramatically from a disease with almost certain mortality from serious comorbidities, to a manageable chronic condition with an extended lifespan. In this paper we present the more recent investigations into the epidemiology, microbiology, and pathogenesis of periodontal diseases in patients with HIV, and the effects of combined antiretroviral therapies on the incidence and progression of these diseases both in adults and perinatally infected children. In addition, comparisons and potential interactions between the HIV-associated microbiome, host responses, and pathogenesis in the oral cavity with the gastrointestinal tract and other areas of the body are presented. Also, the effects of HIV and combined antiretroviral therapies on comorbidities such as hyposalivation, dementia, and osteoporosis on periodontal disease progression are discussed.

Abstract
A feedback loop between dysbiotic gut microbiota, increased translocation of microbial products such as lipopolysaccharide, and inflammation has been hypothesized to cause immune system dysfunction in early HIV infection. However, despite evidence of a chronic inflammatory phenotype in patients on antiretroviral therapy (ART), the role of oral microbiota in systemic immune activation and the relationship between oral and gut bacterial and fungal diversity have not been explored. Our study suggests a crucial role for oral bacterial and fungal communities in long-term systemic immune activation in patients on ART, expanding the current paradigm focused on gut bacteria. Our results indicate that interventions targeting both inflammation and microbial diversity are needed to mitigate oral inflammation-related comorbidities, particularly in HIV-positive patients. More broadly, these findings can bolster general models of microbiome-mediated chronic systemic immune activation and aid the development of precise microbiota-targeted interventions to reverse chronic inflammation. Despite evidence of a chronic inflammatory phenotype in people living with HIV (PLWH) on antiretroviral therapy (ART), the role of oral microbiota in chronic immune activation has not been fully explored. We aimed to determine the relationship between oral and gut microbiome diversity and chronic systemic inflammation in ART-treated PLWH with prevalent severe periodontitis, an inflammatory condition commonly associated with HIV infection. We assessed bacterial and fungal communities at oral and gastrointestinal sites in a cohort (n = 52) of primarily postmenopausal women on ART using 16S rRNA and internal transcribed spacer (ITS) sequencing and measured cellular and soluble markers of inflammation and immune dysfunction. Linear mixed-effect regression and differential abundance analyses were used to associate clinical characteristics and immunological markers with bacterial and fungal diversity and community composition. Bacterial α-diversity in plaque, saliva, and gut was associated with different immunological markers, while mycobial diversity was not associated with soluble or cellular biomarkers of immune stimulation or T cell dysfunction. Furthermore, lipopolysaccharide-positive (LPS+) bacteria previously linked to inflammatory outcomes were enriched at oral sites in patients with severe periodontitis. Fungal α-diversity was reduced in plaque from teeth with higher clinical attachment loss, a marker of periodontitis, and in saliva and plaque from patients with a history of AIDS. Our results show that both bacterial and fungal oral microbiome communities likely play a role in chronic systemic immune activation in PLWH. Thus, interventions targeting both inflammation and the microbiome, particularly in the oral cavity, may be necessary to reduce chronic immune dysregulation in patients with HIV.

Abstract
People living with human immunodeficiency virus (PLHIV) are at high risk of developing non-HIV related comorbidities, particularly at older ages. In a retrospective claims database analysis, we compared PLHIV to a matched, non-HIV cohort to assess the prevalence of comorbidities and healthcare costs in PLHIV and the general non-HIV population in Germany. In total, 2,132 adult patients with HIV were identified in the InGef research database with HIV ICD-10 diagnosis within each year from 2011 to 2014. Of these, 1,969 could be matched to a control cohort of 3,938 individuals (1:2 ratio). Matching criteria included age, gender and socio-economic variables. The prevalence of acute renal disease (0.5% vs. 0.2%, p = 0.045), bone fractures due to osteoporosis (6.4% vs. 2.1%, p<0.001), chronic renal disease (4.3% vs. 2.4%, p<0.001), cardiovascular disease (12.8% vs. 10.4%, p = 0.006), Hepatitis B (5.9% vs. 0.3%, p<0.001) and Hepatitis C infection (8.8% vs. 0.3%, p<0.001) was significantly higher in PLHIV compared to the matched non-HIV cohort. Mean costs excluding costs for antiretroviral therapy (ART) were significantly higher in the HIV cohort (8,049€ vs. 3,658€, p<0.05). On average, PLHIV incurred excess costs of 16,441€ for ART, 2,747€ for pharmaceuticals excluding ART (p<0.05), 1,441€ for outpatient care (p<0.05) and 321€ for inpatient care (p<0.05). Devices and remedies’ costs were significantly higher in the control cohort with excess costs of 113€ (p<0.05). Considering mean total costs, excluding ART, excess costs for PLHIV amounted to 8,049€ (p<0.05). This analysis demonstrated an increased comorbidity and economic burden of PLHIV compared to matched controls. Our findings suggest that HIV remains an area of high unmet medical need. To improve patient outcomes, adequate HIV management including regular monitoring, screening for comorbidities and optimal ART selection throughout the life course of PLHIV are of key importance.

Abstract
Older people living with HIV (PLWH) may have delayed diagnosis and access to care and therefore have poorer disease outcomes. Little is known about HIV care and disease outcomes among older PLWH in China. This retrospective cohort study used data from all adult HIV/AIDS cases during 1988-2017 in Chongqing, China from two national databases. We compared demographic and behavioral profiles, HIV care, virologic suppression, and mortality between two age groups of 18-49 and ≥50 years. Multivariate logistic and cox regression analyses were used to calculate adjusted odds ratio (AOR) and adjusted hazard ratio (AHR) among older versus younger PLWH. Of 46,580 adult HIV/AIDS cases, 76.1% were men and 38.2% were 50 years of age or older. The proportion of older cases in men increased from 2.4% in 2002 to 51.8% in 2017, and in women from 3.3% to 57.9%. Older PLWH had a lower CD4 count than their younger counterparts at HIV diagnosis (median 323 vs. 391 cells/μL; p < .001). The average time from HIV diagnosis to initiation of antiretroviral therapy (ART) were 6.3 months among older and 12.8 months among younger PLWH (p < .001). Nearly one tenth (9.6%) had virologic failure within 12 months of ART initiation, and the odds of virologic failure among older PLWH was 80% higher [AOR 1.8; 95% confidence interval (CI), 1.1-3.0] than among younger ones after controlling for calendar year of initiating ART and other covariates. The mortality rate within 12 months of initiating ART was 9.8 deaths per 100 person years, and the risk of mortality among older PLWH was three times among younger ones (AHR, 3.1; 95% CI, 2.1-4.6). Older people represented an increasing proportion of new HIV/AIDS cases and were more likely to have virologic failure and mortality within 12 months of ART initiation.

Abstract
HIV-associated neurocognitive disorders (HANDs) persist even with virologic suppression on combination antiretroviral therapy (cART), and the underlying pathophysiological mechanisms are not well understood. We performed structural magnetic resonance imaging and MR spectroscopy (MRS) in HIV+ individuals without major neurocognitive comorbidities. Study participants were classified as neurocognitively unimpaired (NU), asymptomatic (ANI), mild neurocognitive disorder (MND), or HIV-associated dementia (HAD). Using structural MRI, we measured volumes of cortical and subcortical gray matter and total and abnormal white matter (aWM). Using single-voxel MRS, we estimated metabolites in frontal gray matter (FGM) and frontal white matter (FWM) and basal ganglia (BG) regions. Adjusted odds ratios were used to compare HAND to NU. Among 253 participants, 40% met HAND criteria (21% ANI, 15% MND, and 4% HAD). Higher risk of HAND was associated with more aWM. Both HAD and MND also had smaller gray and white matter volumes than NU. Among individuals with undetectable plasma HIV RNA, structural volumetric findings were similar to the overall sample. MND had lower FWM creatine and higher FGM choline relative to NU, whereas HAD and ANI had lower BG N-acetyl aspartate relative to NU. In the virologically suppressed subgroup, however, ANI and MND had higher FGM choline compared to NU. Overall, HAND showed specific alterations (more aWM and inflammation; less gray matter volume and lower NAA). Some MR measures differentiated less severe subtypes of HAND from HAD. These MR alterations may represent legacy effects or accumulating changes, possibly related to medical comorbidities, antiretroviral therapy, or chronic effects of HIV brain infection.

Abstract
INTRODUCTION Since the beginning of the epidemic, human immunodeficiency virus (HIV) has taken more than 36 million lives. OBJECTIVE To determine the antiretroviral drug prescription patterns in a population of individuals with HIV infection in Colombia. MATERIALS AND METHODS Cross-sectional study analyzing the profiles of patients treated with antiretroviral drugs between April 1st and September 30th, 2015. The sociodemographic, pharmacological, and comorbidity variables were identified. Individuals with a positive diagnosis of HIV of all ages and both genders were included. RESULTS We found 641 patients with a mean age of 39.0±17 years who were predominantly male (60.2%). The most used medications were lamivudine-zidovudine (51.6%), lopinavir-ritonavir (36%) and efavirenz (24.5%). The combination of lamivudine-zidovudine plus lopinavir-ritonavir was the most prescribed regimen (29.5%), but a total of 80 different regimens was identified. Being an adult between the ages of 45-64 years (OR=2.25; 95%CI 1.367-3.713) was associated with a greater probabilityof receiving 4 or more antiretrovirals. A total of 267 (41.6%) patients used at least one comedication (range: 1-18 drugs), especially anti-ulcer (57.3%), lipid-lowering (28.8%) and anti-hypertensive (28.5%) drugs. CONCLUSIONS Patients undergoing antiretroviral treatment are receiving medications with elevated intrinsic values at the recommended doses and present comorbidities associated with chronic agerelated conditions. However, these patients receive a great variety of regimens that are not included in the clinical practice guidelines.

Abstract
Inflammation occurs after HIV infection and persists, despite highly active antiretroviral therapy (HAART). Diffusion tensor imaging (DTI) measures HIV-associated white matter changes, but can be confounded by inflammation. Currently, the influence of inflammation on white matter integrity in well-controlled HIV+ patients remains unknown. We used diffusion basis spectral imaging (DBSI)-derived cellularity to isolate restricted water diffusion associated with inflammation separated from the anisotropic diffusion associated with axonal integrity. Ninety-two virologically suppressed HIV+ patients on HAART and 66 HIV uninfected (HIV-) controls underwent neuropsychological performance (NP) testing and neuroimaging. NP tests assessed multiple domains (memory, psychomotor speed, and executive functioning). DTI- and DBSI-derived fractional anisotropy (FA) maps were processed with tract-based spatial statistics for comparison between both groups. Cellularity was assessed regarding age, HIV status, and NP. Within the HIV+ cohort, cellularity was compared with clinical (HAART duration) and laboratory measures of disease (eg, CD4 cell current and nadir). NP was similar for both groups. DTI-derived FA was lower in HIV+ compared with HIV- individuals. By contrast, DBSI-derived FA was similar for both groups. Instead, diffuse increases in cellularity were present in HIV+ individuals. Observed changes in cellularity were significantly associated with age, but not NP, in HIV+ individuals. A trend level association was seen between cellularity and HAART duration. Elevated inflammation, measured by cellularity, persists in virologically well-controlled HIV+ individuals. Widespread cellularity changes occur in younger HIV+ individuals and diminish with aging and duration of HAART.

Abstract
PURPOSE The Comparative Outcomes And Service Utilization Trends (COAST) Study in British Columbia (BC), Canada, was designed to evaluate the determinants of health outcomes and health care services use among people living with HIV (PLHIV) as they age in the period following the introduction of combination antiretroviral therapy (cART). The study also assesses how age-associated comorbidities and health care use among PLHIV may differ from those observed in the general population. PARTICIPANTS COAST was established through a data linkage between two provincial data sources: The BC Centre for Excellence in HIV/AIDS Drug Treatment Program, which centrally manages cART dispensation across BC and contains prospectively collected data on demographic, immunological, virological, cART use and other clinical information for all known PLHIV in BC; and Population Data BC, a provincial data repository that holds individual event-level, longitudinal data for all 4.6 million BC residents. COAST participants include 13 907 HIV-positive adults (≥19 years of age) and a 10% random sample inclusive of 516 340 adults from the general population followed from 1996 to 2013. FINDINGS TO DATE For all participants, linked individual-level data include information on demographics, health service use (eg, inpatient care, outpatient care and prescription medication dispensations), mortality, and HIV diagnostic and clinical data. Publications from COAST have demonstrated the significant mortality reductions and dramatic changes in the causes of death among PLHIV from 1996 to 2012, differences in the amount of time spent in a healthy state by HIV status, and high levels of injury and mood disorder diagnosis among PLHIV compared with the general population. FUTURE PLANS To capture the dynamic nature of population health parameters, regular data updates and a refresh of the data linkage are planned to occur every 2 years, providing the basis for planned analysis to examine age-associated comorbidities and patterns of health service use over time.

Abstract
HIV persists within the body despite successful suppression of virus replication with antiretroviral therapy (ART). HIV lurks in latent and active reservoirs, leading to rebound of virus spread if ART is interrupted. The latent HIV reservoir is a natural consequence of the life cycle of HIV, with integration of HIV into the genomes of cells that are or later enter the resting state, resulting in transcriptionally quiescent provirus. Resting CD4 T cells comprise the majority of the latent reservoir, although new evidence points to additional, smaller cellular reservoirs of latent HIV. An alternate, so-called active reservoir of HIV also exists within cells such as those found the B cell follicle of lymph nodes, where expression of HIV RNA can be found, again despite the full suppression of viremia and viral replication. Multiple factors such as the degree of virus exposure, timing of ART, and host factors can influence the size and characteristics of the HIV reservoir. Constructing effective strategies for HIV eradication and measuring their impact will require a sophisticated knowledge of the HIV reservoir.

Abstract
OBJECTIVES A number of studies have been conducted to identify the self-care strategies that are used by persons living with chronic illnesses to manage their symptoms, but little work has been done to identify the primary information source for these self-care strategies. METHODS We conducted an anonymous online survey with 1373 persons living with HIV to identify the self-care strategies they use to manage 28 commonly experienced symptoms. Following their report of their symptoms and self-care strategies, we asked an open-ended question to identify where the participant obtained the information. We applied iterative content analysis of the narrative data and multi-nominal regression to identify which demographic factors were significantly related to each information source category. RESULTS Respondents reported a total of 8539 information sources for their self-care strategies categorized as follows: Common sense/Self-experience, Healthcare professional, Internet, Literature, Multiple Sources, Social Support, and TV ads. CONCLUSIONS We found that respondents with no college education were significantly more likely to report the use of the Internet as the information source for their self-care strategies. On the other hand, males as compared to females were significantly less likely to use the Internet and significantly more likely to use TV ads.

Abstract
PURPOSE Substance use has been linked to the sexual transmission of HIV among gay, bisexual, and other men who have sex with men (MSM) across the lifespan. Among older, HIV-positive, MSM populations, cognitive dysfunction associated with age and HIV disease progression also may play a role in sexual risk-taking. People aged 50 years and older represent a growing proportion of the overall HIV-positive population. This study aimed to explore relationships between substance use and cognitive function, and their impact on condomless anal sex (CAS) among HIV-positive gay, bisexual, and other MSM aged 50 years and older. METHODS Data from a cross-sectional study of HIV-positive MSM, aged 50 and older (N = 169) were gathered using a computer-assisted survey, researcher-administered behavioral and neurocognitive measures. RESULTS More than 50% of the men used substances and had one or more cognitive impairments. However, only 25% were at higher risk for dementia (i.e., two or more cognitive impairments). Multivariable modeling indicated that use of alcohol to intoxication and date of HIV diagnosis were the strongest predictors of CAS in both a model that included dementia risk and a model that included impaired executive function risk. Current illicit substance use was a significant predictor of CAS only in the model that included dementia risk. Those with better cognitive and executive function had higher odds of CAS. However, only executive function was a significant cognitive predictor of CAS. CONCLUSION Further research is needed to clarify the impact of cognitive function and substance use on sexual risk behaviors as these HIV-positive men achieve normal life expectancies, while continuing to use substances and engage in CAS. Furthermore, addiction treatment remains a critical need for this group even as they transition into later adulthood.

Abstract
The prolongation of an active sexual life in addition to unsafe practices are reflected in the possibility of the occurrence of STDs among the elderly. The scope of this study is to analyze the evolving trend of STDs among the elderly in Brazil and in the world and also to identify the main issues addressed in the literature, providing data that can support public policies that address the health of the elderly. A systematic search was performed in the Lilacs, IBECS, Cochrane Library, Medline, SciELO and PubMed databases. Of a total of 979 studies found, 44 matched the inclusion criteria and comprised the sample of the review. Six main themes were identified: risk factors for infection (34 studies); the influence of Sildenafil as a possible factor (18); diagnosis of STDs in general (20); HIV treatment (24); comorbidities related to HIV (24); and the prevention of STDs (20). More than one theme can be found in each study. The conclusion drawn is that this age group remains out of the focus of public policies of health promotion in the STD context. Therefore, there is a need for awareness about the changes in behavior and the epidemiological profile of this population group.

Abstract
HIV-associated neurocognitive disorder (HAND) remains a common cause of cognitive impairment and persists in 15-55% of HIV+ individuals in the combination antiretroviral therapy (CART) era. CART is now the primary treatment for HAND, but it is effective in only a subset of patients. In the pre-CART era, HIV-associated dementia was the most common form of HAND. However, in CART-treated patients, the prevalence of HIV-associated dementia has declined substantially, and milder stages of HAND, i.e., ANI and MND predominate. HIV+ patients with mild neurocognitive disorder (MND) can still have significant functional impairment in some activities of daily living. There have been several other significant changes in the clinical features of HAND in the CART era. The mean survival for an individual diagnosed with HIV dementia has increased dramatically. In HIV+ individuals on CART with a suppressed systemic viral load, the majority of individuals with HAND remain stable, with a small proportion showing deterioration. Extrapyramidal signs are now less common in patients with HAND on CART. In the CART era, HAND may have a mixed pattern of both cortical and subcortical features with greater deficits in executive functioning and working memory. Despite the milder clinical phenotype, in the CART era, patients with HAND still have persistent laboratory and neuroimaging abnormalities in the central nervous system even with systemic viral suppression. As the HIV+ patient population ages, cerebrovascular disease risk factors such as hypertension, diabetes, and hypercholesterolemia are increasingly recognized as risk factors for cognitive impairment in HIV+ patients on CART. HAND remains a common neurological condition globally in the CART era, necessitating the need for new animal models to examine pathogenesis and potential treatments for HAND.

Abstract
The current article discusses the importance of implementing HIV and AIDS education, prevention, and intervention programs that are tailored to women 50 and older and to determine HIV risk factors for this population. A literature search was performed, resulting in 41 relevant articles. The literature underscored the significance of increasing awareness of HIV/AIDS, particularly among older women. HIV risk behaviors and the effect that these behaviors have on HIV transmission and prevention among women 50 and older are described. Prior research findings identified risk categories of older women that may contribute to the transmission of HIV among this particular population, including heterosexual relations, perceived HIV risk, ageism and HIV transmission, biological factors, transfusions, sexual enhancement aids, and health care providers and prevention messages. In addition, previous findings indicate that health care providers have not traditionally targeted women 50 and older for HIV prevention. Health care providers should incorporate discussion of HIV risk and transmission during clinic visits and implement prevention programs that target this population.

Abstract
BACKGROUND Late presentation (LP) at the time of HIV diagnosis is defined as presentation with AIDS whatever the CD4 cell count or with CD4 <350 cells/mm. The objective of our study was to assess the prevalence of non-infectious comorbidities (NICM) and multimorbidity among HIV-positive individuals with and without a history of LP (HIV + LP and HIV + EP, respectively), and compare them to matched HIV-negative control participants from a community-based cohort. The secondary objective was to provide estimates and determinants of direct cost of medical care in HIV patients. METHODS We performed a matched cohort study including HIV + LP and HIV + EP among people attending the Modena HIV Metabolic Clinic (MHMC) in 2014. HIV-positive participants were matched in a 1:3 ratio with HIV-negative participants from the CINECA ARNO database. Multimorbidity was defined as the concurrent presence of ≥2 NICM. Logistic regression models were constructed to evaluate associated predictors of NICM and multimorbidity. RESULTS We analyzed 452 HIV + LP and 73 HIV + EP participants in comparison to 1575 HIV-negative controls. The mean age was 46 ± 9 years, 27.5% were women. Prevalence of NICM and multimorbidity were fourfold higher in the HIV + LP compared to the general population (p < 0.001), while HIV + EP present an intermediate risk. LP was associated with increased total costs in all age strata, but appear particularly relevant in patients above 50 years of age, after adjusting for age, multimorbidity, and antiretroviral costs. CONCLUSIONS LP with HIV infection is still very frequent in Italy, is associated with higher prevalence of NICM and multimorbidity, and contributes to higher total care costs. Encouraging early testing and access to care is still urgently needed.

Abstract
Objectives To develop and validate a model for predicting the risk of hospital admission within 1 year in the HIV population under antiretroviral treatment. Methods We conducted a retrospective observational study. Patients receiving antiretroviral treatment for at least 1 year who were followed by the pharmacy service in a Spanish-speaking hospital between January 2008 and December 2012 were included. Demographics, and clinical and pharmacotherapy variables, were included in the model design. To find prognostic factors for hospital admission a multivariate logistic regression model was created after performing a univariate analysis. Model validity was determined by the shrinkage method and the model discrimination by Harrell's C-index. Results 442 patients were included in the study. The variables 'CD4 count <200 (cells/µL)', 'drug/alcohol use', 'detectable viral load (>50 copies/mL)', 'number of previous admissions', and 'number of drugs different from antiretroviral treatment' were the independent predictors of risk of hospital admission. Probabilities predicted by the model showed an R2=0.98 for the development sample and an R2=0.86 for the validation sample. The Harrell's C index for the development and validation data were 0.82 (95% CI 0.77 to 0.87) and 0.80 (95% CI 0.73 to 0.88), respectively. Conclusions The model developed in this study may be useful in daily practice for identifying HIV patients at high risk of 1-year hospital admission.

Abstract
BACKGROUND Although the prevalence of HIV-infection among individuals ≥ 50 years of age has increased, the impact of HIV-infection on risk of death in this population remains to be established. Our aim was to estimate long-term mortality among HIV-infected individuals who were 50 years or older, when compared with an individually-matched cohort from the background population. METHODS Population-based cohort-study including HIV-infected individuals ≥ 50 years, who were alive 1 year after HIV-diagnosis (n = 2440) and a comparison cohort individually-matched by age and gender extracted from the background population (n = 14,588). Cumulative survival was evaluated using Kaplan-Meier method and Mortality Rate Ratios (MRRs) were estimated using Cox Regression Models. Study period 1996-2014. RESULTS Estimated median survival time from age 50 years for HIV-infected individuals increased from 11.8 years (95% CI: 10.2 to 14.5) during 1996-1999 to 22.8 years (20.0-24.2) in 2006-2014. MRR decreased with increasing age from 3.8 (3.1-4.7) for 50-55 years to 1.6 (1.0-2.6) for 75-80 years. In a cohort of well-treated HIV-infected individuals ≥ 50 years without AIDS-defining events or comorbidity at study inclusion (n = 517). MRR was 1.7 (1.2-2.3) compared with population controls without comorbidity. CONCLUSION Among HIV-infected individuals estimated median survival time from age 50 years has increased by more than 10 years from 1996-1999 to 2006-2014, but is still substantially lower than in the background population. Even among well-treated HIV-infected individuals ≥ 50 years without comorbidity or AIDS-defining events the estimated median survival time remains lower than in the general population.

Abstract
OBJECTIVE HIV-infected older adults (HOA) are at risk of functional decline. Interventions promoting physical activity that can attenuate functional decline and are easily translated into the HOA community are of high priority. We conducted a randomized, controlled clinical trial to evaluate whether a physical activity counseling intervention based on self-determination theory (SDT) improves physical function, autonomous motivation, depression and the quality of life (QOL) in HOA. METHOD In total, 67 community-dwelling HOA with mild-to-moderate functional limitations were randomized to 1 of 2 groups: a physical activity counseling group or the usual care control group. We used SDT to guide the development of the experimental intervention. Outcome measures that were collected at baseline and final study visits included a battery of physical function tests, levels of physical activity, autonomous motivation, depression, and QOL. RESULTS The study participants were similar in their demographic and clinical characteristics in both the treatment and control groups. Overall physical performance, gait speed, measures of endurance and strength, and levels of physical activity improved in the treatment group compared to the control group (p < .05). Measures of autonomous regulation such as identified regulation, and measures of depression and QOL improved significantly in the treatment group compared with the control group (p < .05). Across the groups, improvement in intrinsic regulation and QOL correlated with an improvement in physical function (p < .05). CONCLUSION Our findings suggest that a physical activity counseling program grounded in SDT can improve physical function, autonomous motivation, depression, and QOL in HOA with functional limitations.

Abstract
Background Rates of first antiretroviral therapy (cART) modifications are high in most observational studies. The age-related differences in treatment duration and characteristics of first cART modifications remain underinvestigated. With increasing proportion of older patients in HIV population it is important to better understand age-related treatment effects. Methods Patients were included into this analysis, if being cART naïve at the first visit at the clinic. Follow-up time was measured from the first visit date until first cART modification or 28 February 2013. First cART modification was defined as any change in the third drug component i.e. protease inhibitor (PI), non-nucleoside reverse transcriptase inhibitor (NNRTI), integrase inhibitor or fusion inhibitor. Cox proportional hazard models were used to identify factors related to first cART modification in three age groups: <30, 30–50 and >50. Results In total 2027 patients with 14,965 person-years of follow-up (PYFU) were included. The oldest group included 136 patients with 1901, middle group 1202 with 8416 PYFU and youngest group consisted of 689 patients with 4648 PYFU. Median follow-up time was 5.8 (IQR 3.4–9.4) years, median time on first cART was 4.4 (IQR 2.1–8.5) years. 72.4 % of patients started PI-based and 26.1 % NNRTI-based regimen. In total 1268 (62.5 %) patients had cART modification (non-adherence 30.8 %, toxicity 29.6 %). Durability of first cART was the best in patients over 50 y.o. (log-rank test, p = 0.001). Factors associated with discontinuation in this group were late presentation (HR 0.45, [95 % CI 0.23–0.90], p = 0.02) and PI use (HR 2.17, [95 % CI 1.18–4.0], p = 0.01). Conclusions Rates of first cART modifications or discontinuation were comparable in all groups; however older patients were significantly longer on first cART regimen.

Abstract
A significant increase in the incidence of cognitive impairment in HIV/AIDS patients has been continuously observed. Consequently, three classification categories of cognitive impairment have been proposed: asymptomatic neurocognitive impairment (ANI) and mild neurocognitive disorder (MND), that correspond to the mild and intermediate forms, and HIV-associated dementia (HAD) for the most severe cases. HIV-associated neurocognitive disorders (HAND) is a broad term that encompasses these three categories. Moreover, the application of neuroimaging methods has led to a major breakthrough in understanding of the neurological changes in HIV, providing greater reliability in the exclusion of associated diseases and allowing earlier diagnosis. Therefore, abnormalities and/or specific neuroimaging elements may soon be incorporated into the HAND classification criteria, which will be of great value in the management of these diseases, including in the optimization of high CNS penetration antiretroviral regimens.

Abstract
Treatment of HIV now occurs largely within the primary care setting, and the principal focus of most visits has become the management of chronic disease states. The clinical pharmacist's potential role in improving chronic disease outcomes for HIV patients is unknown. A retrospective cohort study was performed for HIV-positive patients also diagnosed with diabetes, hypertension, or hyperlipidemia. Characteristics and outcomes in 96 patients treated by an interdisciplinary team that included a clinical pharmacist (i.e., the intervention group) were compared to those in 50 patients treated by an individual healthcare provider (i.e., the control group). Primary outcomes were changes from baseline over 18 months of HbA1c, low density lipoprotein (LDL), and blood pressure, respectively. Secondary outcomes included number of drug-drug interactions, HIV viral load, CD4 count, percent change in smoking status, and percent of patients treated to cardiovascular guideline recommendations. The interdisciplinary team had a significant improvement in lipid management over the control group (LDL: -8.8 vs. +8.4 mg/dL; p=0.014), and the smoking cessation rate over the study period was doubled in the interdisciplinary group (20.4% vs. 11.8%). Among those with an indication for aspirin, a significantly higher percentage of patients were prescribed the medication in the interdisciplinary group compared to the control group (85.5% vs. 64.9%; p=0.014). An informal cost analysis estimated savings of more than $3000 per patient treated by the interdisciplinary team. Based on these results, pharmacist involvement in an HIV primary care clinic appears to lead to more appropriate management of chronic co-morbidities in a cost-effective manner.

Abstract
PURPOSE OF REVIEW HIV enters the brain after initial infection, and with time can lead to HIV-associated neurocognitive disorders (HAND). Although the introduction of combination antiretroviral therapy has reduced the more severe forms of HAND, milder forms are still highly prevalent. The 'gold standard' for HAND diagnosis remains detailed neuropsychological performance testing but additional biomarkers (including neuroimaging) may assist in early detection of HAND. RECENT FINDINGS We review the application of recently developed noninvasive MRI and PET techniques in HIV+ individuals. In particular, magnetic resonance spectroscopy may be more sensitive than conventional MRI alone in detecting HIV associated changes. Diffusion tensor imaging has become increasingly popular for assessing changes in white matter structural integrity due to HIV. Both functional MRI and PET have been limitedly performed but could provide keys for characterizing neuropathophysiologic changes due to HIV. SUMMARY It is hoped that continued progress will allow novel neuroimaging methods to be included in future HAND management guidelines.

Abstract
Owing to the improved longevity afforded by combination antiretroviral therapy (cART), HIV-infected individuals are developing several non-AIDS-related comorbid conditions. Consequently, medical management of the HIV-infected population is increasingly complex, with a growing list of potential drug-drug interactions (DDIs). This article reviews some of the most relevant and emerging potential interactions between antiretroviral medications and other agents. The most common DDIs are those involving protease inhibitors or non-nucleoside reverse transcriptase inhibitors, which alter the cytochrome P450 enzyme system and/or drug transporters such as p-glycoprotein. Of note are the new agents for the treatment of chronic hepatitis C virus infection. These new classes of drugs and others drugs that are increasingly used in this patient population represent a significant challenge with regard to achieving the goals of effective HIV suppression and minimization of drug-related toxicities. Awareness of DDIs and a multidisciplinary approach are imperative in reaching these goals.

Abstract
Background Rising HIV infection rates have been observed among elderly people in Guangxi, China. Inexpensive aphrodisiacs are available for purchase in suburban and rural areas. This study aims to investigate the association between aphrodisiac use and increased HIV risk for middle-aged and elderly men in Guangxi. Methods A matched case-control study of aphrodisiac use-associated HIV infection was performed among male subjects over 50 years old who were clients of low-cost commercial sex venues in Guangxi. The cases were defined as clients who were HIV-positive and two controls were selected for each case. The cases and the controls were matched on the visited sex venue, age (±3 years), number of years of purchasing sex (±3 years), and educational attainment. Subjects were interviewed and tested for HIV. Paired t-test or McNemar Chi-squared test were used to compare the characteristics between the cases and controls. A stepwise conditional logistic regression was used to identify risk factors associated with HIV infection. Findings This study enrolled 103 cases and 206 controls. Aphrodisiac use (P = 0.02, odds ratio (OR) = 1.81, 95% CI = 1.08–3.04), never using condom during commercial sex encounter (P = 0.03, odds ratio (OR) = 1.82, 95% CI = 1.08–3.07), and lacking a stable partner (P = 0.03, odds ratio (OR) = 1.76, 95% CI = 1.05–2.98) were found to be risk factors for HIV infection among the study groups. For subjects reporting aphrodisiac use, the frequency of purchasing sex was positively correlated with the frequency of aphrodisiac use (r = 0.3; p = 0.02). Conclusions Aphrodisiac use was significantly associated with increased HIV infection risk in men over 50 years old who purchased commercial sex in the suburban and rural areas of Guangxi. Further research and interventions should address the links between aphrodisiac use, commercial sex work, condom use, and increased HIV transmission.

Abstract
PURPOSE OF REVIEW This review considers the evidence available to guide clinicians in their choice of optimal antiretroviral therapy (ART) for women with HIV. RECENT FINDINGS Cohort and clinical trial data indicate that ART is as efficacious in women as men, although women are more likely to discontinue therapy, which compromises effectiveness. For many drugs, women have higher plasma levels than men, although whether this is secondary to differing metabolism in women or because on average women have a lower body mass than men is not clear. For many drugs, women experience more adverse events secondary to ART. Opinion on the use of efavirenz in pregnancy differs between countries. The average age of women with HIV is increasing. Although virological responses to ART are not affected by age, immunological responses may be poorer. Older women with HIV face issues such as neurocognitive impairment, early menopause, osteoporosis and polypharmacy, which will have the potential to impact on their use of ART. SUMMARY When planning ART regimes with women, clinicians need to be mindful of the woman's social situation and stage in the life course, as well as the scientific data on individual drug effectiveness according to sex.

Aging of the human innate immune system in HIV infection. Curr Opin Immunol 2014; 29:127-36. [PMID: 24997358 DOI: 10.1016/j.coi.2014.06.007] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2014] [Revised: 06/06/2014] [Accepted: 06/09/2014] [Indexed: 02/07/2023]
Abstract
HIV infection is associated with a chronic inflammatory state arising from multiple factors, including innate immune recognition of HIV, increased microbial translocation, and release of endogenous ligands from damaged cells (such as CD4 T cells). In many respects, this heightened pro-inflammatory environment resembles that associated with aging in the absence of HIV infection, and evidence of dysregulated innate immune responses can be found in not only older HIV-negative adults, but also adults with HIV infection. While the study of innate immune aging in HIV infection is still in its early stages, it seems likely that at least additive, or potentially synergistic effects of aging and HIV infection will be found.

Accelerated aging of selective brain structures in human immunodeficiency virus infection: a controlled, longitudinal magnetic resonance imaging study. Neurobiol Aging 2014; 35:1755-68.

Abstract
Advances in treatment have transformed human immunodeficiency virus (HIV) infection from an inexorable march to severe morbidity and premature death to a manageable chronic condition, often marked by good health. Thus, infected individuals are living long enough that there is a potential for interaction with normal senescence effects on various organ systems, including the brain. To examine this interaction, the brains of 51 individuals with HIV infection and 65 uninfected controls were studied using 351 magnetic resonance imaging and a battery of neuropsychological tests collected 2 or more times over follow-up periods ranging from 6 months to 8 years. Brain tissue regions of interest showed expected age-related decrease in volume; cerebrospinal fluid-filled spaces showed increase in volume for both groups. Although HIV-infected individuals were in good general health, and free of clinically-detectable dementia, several brain regions supporting higher-order cognition and integration of functions showed acceleration of the normal aging trajectory, including neocortex, which extended from the frontal and temporal poles to the parietal lobe, and the thalamus. Beyond an anticipated increase in lateral ventricle and Sylvian fissure volumes and decrease in tissue volumes (specifically, the frontal and sensorimotor neocortices, thalamus, and hippocampus) with longer duration of illness, most regions also showed accelerated disease progression. This accelerated loss of cortical tissue may represent a risk factor for premature cognitive and motor compromise if not dementia. On a more promising note, HIV-infected patients with increasing CD4 counts exhibited slower expansion of Sylvian fissure volume and slower declines of frontal and temporoparietal cortices, insula, and hippocampus tissue volumes. Thus, attenuated shrinkage of these brain regions, likely with adequate pharmacologic treatment and control of further infection, has the potential of abating decline in associated higher-order functions, notably, explicit memory, executive functions, self-regulation, and visuospatial abilities.

Abstract
Human immunodeficiency virus (HIV) enters the brain soon after seroconversion and can cause HIV-associated neurocognitive disorders (HAND). Although the more severe and progressive forms of HAND are less prevalent due to combination antiretroviral therapy (cART), ∼ 40% of HIV-infected (HIV+) patients continue to have cognitive impairment. Some HIV+ individuals who have effective plasma HIV-1 RNA suppression with cART still develop HAND. It is often difficult to diagnose HAND in the outpatient setting as detailed neuropsychological performance testing is required. Additional biomarkers that are relatively easy to obtain and clinically relevant are needed for assessing HIV-associated neuropathologic changes. Recently developed noninvasive magnetic resonance imaging (MRI) techniques have great potential to serve as biomarkers. The authors review the application of some of these neuroimaging techniques, magnetic resonance spectroscopy (MRS), volumetric MRI, diffusion tensor imaging (DTI), functional MRI (fMRI), in HIV+ individuals. Each of the neuroimaging methods offers unique insight into mechanisms underlying neuroHIV, could monitor disease progression, and may assist in evaluating the efficacy of particular cART regimens. It is hoped that considerable progress will continue to occur such that some of these neuroimaging methods will be incorporated across multiple sites and included in future HAND guidelines.

Abstract
BACKGROUND A widened electrocardiographic spatial QRS-T angle has been shown to be predictive of cardiovascular disease in HIV-infected individuals. However, determinants and risk factors of developing widened QRS-T angle over time in this population remain unknown. METHODS AND RESULTS Spatial QRS-T angle was automatically measured from standard electrocardiogram of 1444 HIV-infected individuals without baseline widened spatial QRS-T angle from the Strategies for Management of Antiretroviral Therapy [SMART], a clinical trial comparing two antiretroviral treatment strategies [Drug Conservation (DC) vs. Viral Suppression (VS)]. Conditional logistic regression analysis was used to examine the association between baseline characteristics and incident widened spatial QRS-T angle (a new angle>93° in males and>74° in females). During 2544 person-years of follow-up, 199 participants developed widened angle at a rate of 7.8 per 100 person-years. In unadjusted models, female sex, black race (vs. white), DC treatment strategy, current and past smokers (vs. never), history of alcohol abuse, greater body mass index, history of diabetes and higher levels of hs-C-reactive protein were associated with incident widened spatial QRS-T angle. When these variables were entered together in the same model with adjustment for demographics and treatment strategy, DC treatment strategy [OR (95% CI): 1.50 (1.09, 2.07)], female gender [1.69 (1.17, 2.45)], current and past smoking (vs. never) [2.49 (1.63, 3.81) and 1.93 (1.21, 3.09), respectively], and diabetes [2.28 (1.33, 3.91)] predicted incident widened spatial QRS-T angle. CONCLUSIONS Drug conservation treatment strategy, female gender, smoking, and diabetes are independently predictive of incident widened spatial QRS-T angle in HIV-infected individuals.

Abstract
BACKGROUND Adults aging with HIV infection are at risk for age-related comorbidities and syndromes, such as frailty. The objective of this study was to evaluate the expression and predictors of the frailty phenotype (FP) among HIV-infected (HIV+) and HIV-uninfected (HIV-) men who have sex with men. METHODS A prospective, observational cohort study was nested in the Multicenter AIDS Cohort Study from October 2007-September 2011. FP conversion was defined as the onset of FP over two consecutive study visits. Adjusted odds ratios and 95% confidence intervals ([,]) for FP conversion were estimated using logistic regression models with generalized estimating equations. RESULTS Of 10,571 completed study visits from 1,946 men who have sex with men, 12% and 9% were FP+ among HIV+ and HIV- men, respectively (p = .002). The proportion of FP+ visits increased with age regardless of HIV status, but was significantly greater in HIV+ compared to HIV- men aged 50-64 years. Of the 10,276 consecutive visit pairs contributed by participants, 5% (537) were classified as FP conversion, and 45% of the men with FP conversion had only one FP+ study visit. FP conversion was significantly associated with a history of AIDS (adjusted odds ratios = 2.26 [1.50, 3.39], but not with HIV+ alone (adjusted odds ratios = 1.26 [0.98, 1.64]). Among men who had one or more FP+ visits, 34% of HIV+ and 38% of HIV- men had less than two comorbidities. CONCLUSIONS These findings suggest that expression of the FP can be measured in men who have sex with men with and without HIV infection and reflects multisystem dysfunction in this population; further investigations are needed to better understand clinical utility.

Abstract
Aiming to explore universal HIV testing, and to understand the exact HIV prevalence in the older general population, we conducted a community-based cross-sectional epidemiological investigation in two counties of Zhejiang province, China. Using census strategy and convenience sampling method, those participants who were older than 50 years and met eligibility criteria were enrolled, and HIV prevalence was presented as a crude infection rate. A total of 215,441 (64.82%) were enrolled into this study, HIV testing was added into their health exam plan and 18 were confirmed as HIV positive, giving a crude rate of 0.84/10,000. HIV prevalence was higher among men than among women in all age groups (p < 0.05). Unlike previous research, 14 cases (78%) still had a relatively high CD4 + count; 17 cases (94%) had been infected by sexual transmission. Active large-scale HIV screening by integrating into routine health care can be an effective strategy to find people living with HIV at relative early stage of disease.

Abstract
Objective The aims of this study were to systematically review epidemiological characteristics in older people living with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) (PLWHA) in low endemic areas of the People’s Republic of China, analyze the causes of death and mortality, and provide a basis for targeted prevention in these populations. Methods Nine counties representative of the distribution and epidemiological factors of the HIV epidemic in Zhejiang Province were selected, and data from 1,115 HIV-positive individuals, including 196 older people (≥50 years), who were confirmed as PLWHA from January 1, 2000 to December 31, 2012, were retrospectively analyzed. Results The proportion of older PLWHA increased from 0% in 2000 to 22.45% in 2012. Sexual transmission was the main route, accounting for 82.65% of infections in this group. Compared with the younger group (range from 14 to 49 years old), the older group had significantly lower CD4+ cell counts (291.64 versus 363.63; P<0.001) when first diagnosed, and more of this group presented in the AIDS state with opportunistic infections (51.02% versus 34.06%; P<0.001). In the older group, 25 (12.76%) patients died directly of AIDS and 171 (87.24%) were censored, and in the younger group 50 (5.44%) patients died directly of AIDS and 869 (94.56%) were censored. Estimated survival time since HIV diagnosis in the older group was 11.54±0.49 years (95% confidence interval [CI] 10.59–12.50), while in the younger group it was 13.85±0.46 years (95% CI 12.94–14.76), the log rank (Mantel–Cox) test gave a chi-square value of 3.83, and there was significant difference between the groups (P<0.05). Conclusion The number of older PLWHA increased steadily over the study period in low HIV endemic provinces of a developing country. Later discovery and preexisting disease perhaps contributed to a shorter estimated survival time for older PLWHA and higher mortality.

Abstract
BACKGROUND HIV-infected individuals may be at increased risk of poor physical function. Chronic inflammation has been associated with decreased physical function in the elderly and may also influence physical function in HIV-infected individuals. METHODS This cross-sectional study assessed physical function in 65 HIV-infected women aged 40 and older on stable antiretroviral treatment using the Short Physical Performance Battery (SPPB): a standardized test of balance, walking speed, and lower- extremity strength developed for elderly populations. The relationship between low SPPB score, selected demographic and medical characteristics, and high inflammatory biomarker profile was analyzed using Fisher's exact test and Wilcoxon rank sum test. RESULTS The median age of subjects was 49 years (interquartile range [IQR] 45-55), and the median CD4 T-cell count was 675 cells/mm(3) (IQR 436-828). Thirteen subjects (20%) had a low SPPB score. Subjects with a low SPPB score were more likely to be cigarette smokers (p=0.03), had more medical comorbidities (p=0.01), and had higher levels of interleukin-6 (IL-6) (p<0.05). They also tended to be older (median age 55 vs. 48, p=0.06), more likely to have diabetes (p=0.07), and have higher levels of soluble tumor necrosis factor-1 (p=0.09). CONCLUSIONS Twenty percent of women aged 40 and older with well-treated HIV had poor physical-function performance, which was associated with the high burden of comorbidities in this population and with increased IL-6. However, it is unclear from this cross-sectional study whether increased inflammation was related to poor physical function or to other factors, such as age and medical comorbidities.

Abstract
Objectives We hypothesized that the increased prevalence of noninfectious comorbidities (NICMs) observed among HIV-infected patients may result in increased direct costs of medical care compared to the general population. Our objective was to provide estimates of and describe factors contributing to direct costs for medical care among HIV-infected patients, focusing on NICM care expenditure. Methods A case-control study analyzing direct medical care costs in 2009. Antiretroviral therapy (ART)-experienced HIV-infected patients (cases) were compared to age, sex, and race-matched adults from the general population, included in the CINECA ARNO database (controls). NICMs evaluated included cardiovascular disease, hypertension, diabetes mellitus, bone fractures, and renal failure. Medical care cost information evaluated included pharmacy, outpatient, and inpatient hospital expenditures. Linear regression models were constructed to evaluate predictors of total care cost for the controls and cases. Results There were 2854 cases and 8562 controls. Mean age was 46 years and 37% were women. We analyzed data from 29,275 drug prescription records. Positive predictors of health care cost in the overall population: HIV infection (β = 2878; confidence interval (CI) = 2001–3755); polypathology (β = 8911; CI = 8356–9466); age (β = 62; CI = 45–79); and ART exposure (β = 18,773; CI = 17,873–19,672). Predictors of health care cost among cases: Center for Disease Control group C (β = 1548; CI = 330–2766); polypathology (β = 11,081; CI = 9447–12,716); age < 50 years (β = 1903; CI = 542–3264); protease inhibitor exposure (per month of use; β = 69; CI = 53–85); CD4 count < 200 cells/mm3 (β = 5438; CI = 3082–7795); and ART drug change (per change; β = 911; CI = 716–1106). Conclusion Total cost of medical care is higher in cases than controls. Lower medical costs associated with higher CD4 strata are offset by increases in the care costs needed for advancing age, particularly for NICMs.

Abstract
The HIV-infected older adult (HOA) community is particularly vulnerable to cognitive impairment. Previous studies in the general older adult population have reported that lower scores on tests of cognitive function often correlate negatively with aerobic fitness [5-7]. HIV-infected individuals have significantly reduced aerobic fitness and physical function compared to HIV-uninfected individuals. Determining important correlates of cognitive ability may be beneficial in not only detecting precursors to future cognitive impairments, but also target areas for interventions. The purpose of this study was to investigate the relationship between cognitive ability and aerobic fitness in HIV-infected older adults. We conducted a cross-sectional study of HOA on antiretroviral therapy (ART) >50 years of age. Domain specific cognitive function was assessed by means of a neuropsychological battery. Aerobic fitness (VO2peak) was assessed using a graded, progressive treadmill test. Thirty-seven HOA on ART (mean±SD: age 59±6 years, BMI 28±5, CD4 663±337 cells/ml, duration since HIV diagnosis 17±7 years; 81% males) completed the cognitive tests. Several domains of cognition were significantly associated with VO2peak by Spearman correlation analysis (p<0.05). By step-wise adjusted regression VO2peak was most frequently and significantly related to many cognitive domains such as verbal and visual memory, visual perception, and language (p<0.05). We found that participants with higher Vo2peak were less likely to have more severe forms of HIV-associated neurocognitive disorders (HAND) such as mild neurocognitive disorder (OR=0.65; p=0.01) and HIV-associated dementia (OR=0.64; p=0.0006). In HOA and in conclusion, aerobic fitness is related to cognitive performance on various tasks. The likelihood of cognitive impairment increased with lower fitness levels. Therefore, increased fitness may serve an important factor in maintenance of cognition and neural integrity for aging HIV-infected individuals. Future prospective and large scale studies are needed to evaluate the effect of fitness and vascular stiffness and function on cognition and brain structure among HOA.

[PMID: 23883539 PMCID: PMC3722415 DOI: 10.7448/ias.16.1.18506] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2012] [Revised: 05/28/2013] [Accepted: 06/19/2013] [Indexed: 11/08/2022] Open
Abstract
INTRODUCTION Research investigating HIV, neurocognition and ageing is well developed using neuropsychometric or other quantitative approaches; however, little is known about individuals' subjective experiences. The purpose of this article is to explore the experiences of men aged 50 and older who self-identify as having HIV-associated neurocognitive challenges. In particular, this study uses the Episodic Disability Framework (EDF) to explore participants' perceptions regarding: 1) symptoms/impairments, difficulties with day-to-day activities, challenges with social inclusion and uncertainty; 2) ageing as related to their HIV-associated neurocognitive challenges, and 3) the episodic nature of their HIV-associated neurocognitive challenges. METHODS This qualitative, interpretive study involved in-depth, semi-structured interviews with 12 men aged 50 years and older who self-identified as having HIV-associated neurocognitive challenges. Participants were recruited from a neurobehavioural research unit (NBRU) at a large hospital in Toronto, Canada. Data were analyzed thematically and with reference to the EDF. RESULTS Participants' experiences reflected all concepts within the EDF to some extent. Difficulties with daily activities were diverse but were addressed using similar living strategies. Participants described challenges with work and social relationships resulting from neurocognitive challenges. Participants downplayed the significance of uncertainty in their lives, which they attributed to effective living strategies. Most men reported confusion regarding the link between their neurocognitive challenges and ageing. Others discussed ageing as an asset that helped with coping. CONCLUSIONS This is the first study to use a disability framework to examine the subjective experiences of men ageing with HIV-associated neurocognitive challenges. Findings reframe the episodic disability experienced by these individuals as being predictably linked to certain triggers. As such, support for managing neurocognitive challenges could focus on triggers that exacerbate the condition in addition to the impairments themselves. The study also describes ageing as not only a source of problems but also as an asset among men growing older with HIV.

Abstract
IMPORTANCE Whether people infected with human immunodeficiency virus (HIV) are at an increased risk of acute myocardial infarction (AMI) compared with uninfected people is not clear. Without demographically and behaviorally similar uninfected comparators and without uniformly measured clinical data on risk factors and fatal and nonfatal AMI events, any potential association between HIV status and AMI may be confounded. OBJECTIVE To investigate whether HIV is associated with an increased risk of AMI after adjustment for all standard Framingham risk factors among a large cohort of HIV-positive and demographically and behaviorally similar (ie, similar prevalence of smoking, alcohol, and cocaine use) uninfected veterans in care. DESIGN AND SETTING Participants in the Veterans Aging Cohort Study Virtual Cohort from April 1, 2003, through December 31, 2009. PARTICIPANTS After eliminating those with baseline cardiovascular disease, we analyzed data on HIV status, age, sex, race/ethnicity, hypertension, diabetes mellitus, dyslipidemia, smoking, hepatitis C infection, body mass index, renal disease, anemia, substance use, CD4 cell count, HIV-1 RNA, antiretroviral therapy, and incidence of AMI. MAIN OUTCOME MEASURE Acute myocardial infarction. RESULTS We analyzed data on 82 459 participants. During a median follow-up of 5.9 years, there were 871 AMI events. Across 3 decades of age, the mean (95% CI) AMI events per 1000 person-years was consistently and significantly higher for HIV-positive compared with uninfected veterans: for those aged 40 to 49 years, 2.0 (1.6-2.4) vs 1.5 (1.3-1.7); for those aged 50 to 59 years, 3.9 (3.3-4.5) vs 2.2 (1.9-2.5); and for those aged 60 to 69 years, 5.0 (3.8-6.7) vs 3.3 (2.6-4.2) (P < .05 for all). After adjusting for Framingham risk factors, comorbidities, and substance use, HIV-positive veterans had an increased risk of incident AMI compared with uninfected veterans (hazard ratio, 1.48; 95% CI, 1.27-1.72). An excess risk remained among those achieving an HIV-1 RNA level less than 500 copies/mL compared with uninfected veterans in time-updated analyses (hazard ratio, 1.39; 95% CI, 1.17-1.66). CONCLUSIONS AND RELEVANCE Infection with HIV is associated with a 50% increased risk of AMI beyond that explained by recognized risk factors.

Abstract
This study was based on an analysis of an existing database compiled from 475 medical records of people living with HIV/AIDS admitted to an acute-care hospital in New York City in 2004. The characteristics of patients with HIV infection that received physical therapy were determined. Differences between patients with HIV infection that did and did not receive physical therapy, as well as predictors of receipt of physical therapy, were identified. The physical therapy subgroup (n = 69) had a mean age of 48.3 years, consisted of more men than women, and was predominately black, with public health insurance. Admissions were commonly due to non-AIDS-defining illness as the primary diagnoses, accompanied by several comorbidities. Admissions often presented with functional deficits, incurred a prolonged length of stay, and required assistance at discharge. Differences existed between the physical therapy subgroup and the non-physical therapy subgroup (n = 406). Predictors of receipt of physical therapy were functional status on admission and length of stay.
