stroke and HIV / AIDS

BACKGROUND: Detailed, comprehensive, and timely reporting on population health by underlying causes of disability and premature death is crucial to understanding and responding to complex patterns of disease and injury burden over time and across age groups, sexes, and locations. The availability of disease burden estimates can promote evidence-based interventions that enable public health researchers, policy makers, and other professionals to implement strategies that can mitigate diseases...

BACKGROUND: Regular, detailed reporting on population health by underlying cause of death is fundamental for public health decision making. Cause-specific estimates of mortality and the subsequent effects on life expectancy worldwide are valuable metrics to gauge progress in reducing mortality rates. These estimates are particularly important following large-scale mortality spikes, such as the COVID-19 pandemic. When systematically analysed, mortality rates and life expectancy allow comparisons of the consequences of causes of death globally and over time, providing a nuanced understanding of the effect of these causes on global populations...

OBJECTIVE: Recent research indicates that autophagy is essential for the rupture of intracranial aneurysm (IA). This study aimed to examine and validate potential autophagy-related genes (ARGs) in cases of IA using bioinformatics analysis. METHODS: Two expression profiles (GSE54083 and GSE75436) were obtained from the Gene Expression Omnibus database. Differentially expressed ARGs (DEARGs) in cases of IA were screened using GSE75436, and enrichment analysis and Protein-Protein Interaction (PPI) networks were used to identify the hub genes and related pathways...

BACKGROUND: Despite advancements in the management of HIV infection, the factors contributing to stroke development among HIV-positive individuals remain unclear. This systematic review and meta-analysis aim to identify and evaluate the relative risk factors associated with stroke susceptibility in the HIV population. METHODS: A comprehensive search was conducted in PubMed, Scopus, and Web of Science databases to identify studies investigating the risk of stroke development in HIV patients and assessing the role of different risk factors, including hypertension, diabetes, dyslipidemia, smoking, sex, and race...

A male in his late 30s was found dead in his home. He was diagnosed with human immunodeficiency virus (HIV) about six years prior. The HIV infection was well controlled before his death. He was 166 cm in height and 75 kg in weight. Aside from discoloration of the skin on the right lower patellar, there were no obvious injuries. His brain weighed 1456 g. A cut surface of the brain revealed left thalamic hemorrhage. Histologically, infiltration of phagocytic cells was observed in the bleeding site. Thalamic hemorrhage was considered to be his cause of death in this case...

The discovery of the 32-bp deletion allele of the chemokine receptor gene CCR5 showed that homozygous carriers display near-complete resistance to HIV infection, irrespective of exposure. Algorithms of molecular evolutionary theory suggested that the CCR5- ∆ 32 mutation occurred but once in the last millennium and rose by strong selective pressure relatively recently to a ~10% allele frequency in Europeans. Several lines of evidence support the hypothesis that CCR5- ∆ 32 was selected due to its protective influence to resist Yersinia pestis, the agent of the Black Death/bubonic plague of the 14th century...

BACKGROUND: HIV and hepatitis C virus (HCV) are associated with increased risk of carotid artery atherosclerotic plaque and stroke. We examined associations of HIV- and HCV-related factors with echomorphologic features of carotid artery plaque. METHODS: This cross-sectional study included participants from the MACS (Multicenter AIDS Cohort Study)/WIHS (Women's Interagency HIV Study) Combined Cohort Study who underwent high-resolution B-mode carotid artery ultrasound...

BACKGROUND: Atrial fibrillation (AF) is the leading cause of a surge in hospital expenses for the treatment of strokes. However, evidence regarding clinical features and survival of patients admitted with acute ischemic stroke (AIS) plus AF in Ethiopia is lacking. OBJECTIVE: We assess clinical characteristics, survival, and predictors of mortality of patients with acute ischemic stroke and atrial fibrillation among patients admitted to Tertiary Care Hospitals in Amhara regional state...

OBJECTIVES: We aimed to prospectively describe incident cardiovascular events among people living with HIV (PLWH) in northern Tanzania. Secondary aims of this study were to understand non-communicable disease care-seeking behaviour and patient preferences for cardiovascular care and education. DESIGN: A prospective observational study. SETTING: This study was conducted at the Majengo HIV Care and Treatment Clinic, an outpatient government-funded clinic in Moshi, Tanzania PARTICIPANTS: Adult patients presenting to an HIV clinic for routine care in northern Tanzania were enrolled from 1 September 2020 to 1 March 2021...

BACKGROUND: COVID-19 experiences on noncommunicable diseases (NCDs) from district-level hospital settings during waves I and II are scarcely documented. The aim of this study is to investigate the NCDs associated with COVID-19 severity and mortality in a district-level hospital with a high HIV/TB burden. METHODS: This was a retrospective observational study that compared COVID-19 waves I and II at Khayelitsha District Hospital in Cape Town, South Africa. COVID-19 adult patients with a confirmed SARS-CoV-2 polymerase chain reaction (PCR) or positive antigen test were included...

OBJECTIVES: To define the frequency, risk factors, and clinical outcomes of both AIDS-defining and non-AIDS-defining neurologic infections among people with HIV (PWH). DESIGN: We conducted a retrospective observational cohort study by linking the clinical database at the Southern Alberta HIV Clinic (SAC) with the regional hospital and microbiology databases to identify cases and the associated morbidity and mortality for these neurologic infections from 1995-2018...

We investigated whether blood telomere length (TL), epigenetic age acceleration (EAA), and soluble inflammatory monocyte cytokines are associated with cardiovascular events or diabetes (DM) in people living with HIV (PLHIV). This was a case-control study nested in the Spanish HIV/AIDS Cohort (CoRIS). Cases with myocardial infarction, stroke, sudden death, or diabetes after starting antiretroviral therapy were included with the available samples and controls matched for sex, age, tobacco use, pre-ART CD4 cell count, viral load, and sample time-point...

DESIGN: A multicentre cross-sectional study. SETTING: The study was conducted in Wolaita Sodo University Teaching Referral Hospital and Sodo Health Centre, Southern Ethiopia, from 1 July 2020 to 30 September 2020. PARTICIPANTS: Four hundred and seventeen HIV-positive women on antiretroviral treatment attending public health facilities were approached during the study period...

BACKGROUND: This study aimed to determine the correlation between human-immunodeficiency-virus (HIV) infection and stroke, as well as to estimate the global, regional, and national burden of HIV-associated stroke. METHODS: A registered meta-analysis was performed by searching PubMed, Embase, and Web of Science for relevant literature up to October 31, 2022. The pooled relative risk of stroke in HIV-infected people was calculated using a random-effects model. HIV prevalence and disability-adjusted life years (DALYs) datasets were obtained from the Joint United Nations Program on HIV and AIDS, and the Global Health Data Exchange, respectively...

OBJECTIVES: The advent of antiretroviral therapy (ART) has reduced AIDS-related morbidity and mortality among people living with HIV (PLWH). Due to increased survival, PLWH have now been found to be at risk of chronic conditions related to ageing, such as cardiovascular disease (CVD). Hypertension is common in PLWH and is a major risk factor for the development of CVD. We conducted a systematic literature review to evaluate the research evidence on longitudinal blood pressure (BP) trajectories following ART initiation in PLWH...

OBJECTIVE: We aimed to obtain more precise estimates of stroke to address the wide variation of stroke burden among people living with HIV (PLWH) in different clinical settings. DESIGN: Systematic review and meta-analysis. METHODS: We systematically searched PubMed, EMBASE, and Web of Science for original articles reporting the prevalence and incidence of stroke among PLWH up to November 23, 2022. Der Simonian-Laird random effects were used to obtain pooled estimates and 95% confidence intervals (CIs)...

HIV-associated comorbidities, such as ischemic stroke, are prevalent in people with HIV (PWH). Several studies both in animal models and humans have revealed an association between activation of the inflammasome in HIV-1 infection and stroke. The gut microbiota is an important component in controlling neuroinflammation in the CNS. It has also been proposed to be involved in the pathobiology of HIV-1 infection, and has been associated with an increase in activation of the inflammasome. In this review, we provide an overview of the microbiota-gut-inflammasome-brain axis, focusing on the NLRP3 inflammasome and dysregulation of the microbiome as risk factors that may contribute to the outcome of ischemic stroke and recovery in PWH...

INTRODUCTION: Integrase strand transfer inhibitor (INSTI)-containing antiretroviral therapy (ART) has been associated with weight gain, though there is limited information on associations between ART-related weight gain and cardiometabolic outcomes among people living with HIV-1 (PLWH). We, therefore, evaluated risks of incident cardiometabolic outcomes following INSTI versus non-INSTI-based ART initiation in the United States. METHODS: We conducted a retrospective study using IBM MarketScan Research Databases (12 August 2012-31 January 2021)...

BACKGROUND: The protective advantage against atherosclerotic cardiovascular disease (ASCVD) experienced by women compared to men in the general population is diminished in some high- risk populations. People living with HIV have a higher risk for ASCVD compared to the general population. OBJECTIVE: Compare the incidence of ASCVD among women versus men living with HIV. METHODS: We analyzed data from women (n = 17,118) versus men (n = 88,840) with HIV, and women (n = 68,472) and men (n = 355,360) matched on age, sex, and calendar year of enrollment without HIV who had commercial health insurance in the MarketScan database between 2011 and 2019...
