First-ever acute ischemic strokes in HIV-infected persons: A case-control study from stroke units. Ann Clin Transl Neurol 2024; 11:916-925. [PMID: 38287505 PMCID: PMC11021677 DOI: 10.1002/acn3.52008] [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: 09/19/2023] [Revised: 12/05/2023] [Accepted: 01/09/2024] [Indexed: 01/31/2024] Open
Abstract
OBJECTIVE The stroke risk for persons living with human immunodeficiency virus (PLHIVs) doubled compared to uninfected individuals. Stroke-unit (SU)-access, acute reperfusion therapy-use and outcome data on PLHIVs admitted for acute ischemic stroke (AIS) are scarce. METHODS AIS patients admitted (01 January 2017 to 31 January 2021) to 10 representative Paris-area SUs were screened retrospectively from the National Hospitalization Database. PLHIVs were compared to age-, initial NIHSS- and sex-matched HIV-uninfected controls (HUCs). Outcome was the 90-day modified Rankin Scale score. RESULTS Among 126 PLHIVs with confirmed first-ever AIS, ~80% were admitted outside the thrombolysis-administration window. Despite antiretrovirals, uncontrolled plasma HIV loads exceeded 50 copies/mL (26% of all PLHIVs; 38% of those ≤55 years). PLHIVs' stroke causes by decreasing frequency were large artery atherosclerosis (LAA), undetermined, other cause, cerebral small-vessel disease (CSVD) or cardioembolism. No stroke etiology was associated with HIV duration or detectable HIVemia. MRI revealed previously unknown AIS in one in three PLHIVs, twice the HUC rate (p = 0.006). Neither group had optimally controlled modifiable cardiovascular risk factors (CVRFs): 20%-30% without specific hypertension, diabetes, and/or dyslipidemia treatments. Their stroke outcomes were comparable. Multivariable analyses retained good prognosis associated solely with initial NIHSS or reperfusion therapy. Older age and hypertension were associated with CSVD/LAA for all PLHIVs. Standard neurovascular care and reperfusion therapy were well-tolerated. INTERPRETATION The high uncontrolled HIV-infection rate and suboptimal CVRF treatment support heightened vigilance to counter suboptimal HIV suppression and antiretroviral adherence, and improve CVRF prevention, mainly for younger PLHIVs. Those preventive, routine measures could lower PLHIVs' AIS risk.

Abstract
The relationship between infections and stroke has not been fully characterized, probably delaying the development of specific treatments. This narrative review addresses mechanisms of stroke linked to infections, including hypercoagulability, endothelial dysfunction, vasculitis, and impaired thrombolysis. SARS-CoV-2, the virus that causes COVID-19, may promote the development of stroke, which may represent its most severe neurological complication. The development of specific therapies for infection-associated stroke remains a profound challenge. Perhaps the most important remaining issue is the distinction between infections that trigger a stroke versus infections that are truly incidental. This distinction likely requires the establishment of appropriate biomarkers, candidates of which are elevated levels of fibrin D-dimer and anticardiolipin/antiphospholipid antibodies. These candidate biomarkers might have potential use in identifying pathogenic infections preceding stroke, which is a precursor to establishing specific therapies for this syndrome.

Abstract
PURPOSE OF REVIEW We aim to review the neurological complications of HIV and the social, cultural, and economic inequalities that contribute to disparities in neuroHIV care. RECENT FINDINGS Disparities in diagnostics and care of patients with neurological infections and non-infectious conditions associated with HIV in both high-income and low-to-middle-income countries (LMIC) are common. The COVID-19 pandemic has exacerbated these disparities. Factors, such as HIV-related stigma, may deter people from accessing HIV treatment. First-line recommended treatments for neurological infections are not available in many LMICs, leading to inadequate treatment and exposure to agents with more harmful side effect profiles. Access-related factors, such as lack of transportation, lack of health insurance, and inadequate telehealth access, may increase the risk of HIV-related neurological complications. Further research is needed to increase awareness of neurological complications among providers and PWH, and regional guidelines should be considered to better address these complications.

Abstract
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. We also focus on the potential of targeting the NLRP3 inflammasome as a novel therapeutic approach for PWH who are at risk of developing cerebrovascular diseases.

Abstract
More than 1.2 million people in the United States have Human Immunodeficiency Virus (HIV) infections but 13% of these people are unaware of their HIV infection. Current combination antiretroviral therapy (ART) does not cure HIV infection but rather suppresses the infection with the virus persisting indefinitely in latent reservoirs in the body. As a consequence of ART, HIV infection has changed from a fatal disease in the past to a chronic disease today. Currently in the United States, more than 45% of HIV+ individuals are greater than 50 years of age and 25% will be greater than 65 years of age by 2030. Atherosclerotic cardiovascular disease (CVD), including myocardial infarction, stroke, and cardiomyopathy, is now the major cause of death in HIV+ individuals. Novel risk factors, including chronic immune activation and inflammation in the body, antiretroviral therapy, and traditional CVD risk factors, such as tobacco and illicit drug use, hyperlipidemia, the metabolic syndrome, diabetes mellitus, hypertension, and chronic renal disease, contribute to cardiovascular atherosclerosis. This article discusses the complex interactions involving HIV infection, the novel and traditional risk factors for CVD, and the antiretroviral HIV therapies which can contribute to CVD in HIV-infected people. In addition, the treatment of HIV+ patients with acute myocardial infarction, stroke, and cardiomyopathy/heart failure are discussed. Current recommended ART and their major side effects are summarized in table format. All medical personnel must be aware of the increasing incidence of CVD on the morbidity and mortality in HIV infected patients and must be watchful for the presence of CVD in their patients with HIV.

Abstract
Human immunodeficiency virus (HIV) infection was associated with increased morbidity and mortality, predominantly for opportunistic infections, before using antiretroviral therapy. With this, patients have experienced increased survival and cardiovascular compromise too. The etiology of these clinical conditions could be related to the infection itself, adverse events associated with antiretroviral therapy, or adverse events produced by the combination with other drugs. Some of these conditions have an acute onset, and their rapid recognition is vital for a better prognosis.

Abstract
Stroke is a debilitating neurologic condition characterized by an interruption or complete blockage of blood flow to certain areas of the brain. While the primary injury occurs at the time of the initial ischemic event or hemorrhage, secondary injury mechanisms contribute to neuroinflammation, disruption of the blood-brain barrier (BBB), excitotoxicity, and cerebral edema in the days and hours after stroke. Of these secondary mechanisms of injury, significant dysregulation of various immune populations within the body plays a crucial role in exacerbating brain damage after stroke. Pathological activity of glial cells, infiltrating leukocytes, and the adaptive immune system promote neuroinflammation, BBB damage, and neuronal death. Chronic immune activation can additionally encourage the development of neurologic deficits, immunosuppression, and dysregulation of the gut microbiome. As such, immunotherapy has emerged as a promising strategy for the clinical management of stroke in a highly patient-specific manner. These strategies include regulatory T cells (Tregs), cell adhesion molecules, cytokines, and monoclonal antibodies. However, the use of immunotherapy for stroke remains largely in the early stages, highlighting the need for continued research efforts before widespread clinical use.

Abstract
Background Human Immunodeficiency Virus (HIV) vasculopathy encompasses the development of aneurysms, stenosis and vessel occlusions. Intracranial fusiform aneurysms in Human Immunodeficiency Virus (HIV) were originally described in children; however, HIV-associated aneurysms are increasingly recognized in adults. Purpose: We present two cases to highlight the spectrum of severity and outline instructive clinical courses. Results Case one is a 52-year-old woman with HIV, Acquired Immunodeficiency Syndrome (AIDS)-defining progressive multifocal leukoencephalopathy (PML) and an 18 years course of cerebral aneurysms, aneurysm thrombosis and the development of right middle cerebral artery (MCA) moyamoya pattern collaterals. Case two is a 55-year-old man with AIDS-defining cerebral toxoplasmosis, complicated by IRIS and anterior and posterior circulation fusiform aneurysm formation. Conclusions: The combination of both fusiform abnormalities and Moyamoya, discussed in our first case has not been previously described. In comparison, our second case actually demonstrated improvement in vasculopathy after nine-months of antiretroviral therapy (ART) adherence.

Abstract
A 35-year-old Iranian man with an 18-year history of human immunodeficiency virus (HIV) infection developed sudden left-sided hemiparesis and mild dysarthria. Based on laboratory results, brain and neck computerized tomography angiography (CTA), echocardiography, hypercoagulability tests, and vasculitis tests, the patient was diagnosed with a stroke with multiple intracranial aneurysms secondary to HIV. Cerebral aneurysms and stroke are uncommon in HIV-infected patients, and the aneurysms' exact cause and risk factors are unknown. There is currently no effective regimen or definitive treatment for HIV-associated vasculitis. In the present study, the patient recovered without any neurological deficits following treatment with oral prednisolone, combined with combination antiretroviral therapy (cART), valacyclovir, and antiplatelet medication. Furthermore, after 2 months of immunosuppressive treatment, all imaging abnormalities improved, and no new events were observed at the 20-month follow-up. To the best of our knowledge, this is the first case in which a patient with HIV-associated vasculopathy and stroke has survived successfully, and all angiographic abnormalities completely eliminated.

Abstract
ABSTARCTIntroduction: Cardiovascular disease (CVD) continues to be an essential cause of morbidity and mortality among people living with human immunodeficiency virus infection (PLWH). Since the bulk of cardiovascular risk (CVR) factors are shared between PLWH and the general population, prevention and treatment strategies are similar. However, there are CVR factors particular to PLWH, which need separate consideration. These factors are those HIV-dependent, those related to HIV-derived consequences, and combination antiretroviral therapy (cART)-dependent.Areas covered: In this review, the authors discuss the management of CVD in PLWH, with a special interest in pharmacological treatment and drug-drug interactions with cART.Expert opinion: In recent years, we have witnessed a decreased CVD morbidity and mortality in PLWH, which probably reflects an improvement in the management of CVR factors and CVD in these patients, partially thanks to new developments in antiretroviral therapy. Therefore, although there is still room for improvement, at present, the old desideratum of equaling PLWH and the general population in terms of CVD incidence and prognosis is a little closer.

Abstract
A 56-year-old male with human immunodeficiency virus required hospitalization due to the onset of both dyspnea and asthenia. A computed tomography of the chest exam showed the radiological pattern of coronavirus SARS-CoV-2 pulmonary involvement. Based on immunochromatographic analysis, the patient evolved as a reagent for immunoglobulin M (IgM) and immunoglobulin G (IgG) anti-SARS-CoV-2 antibodies. The individual developed complete hemiparesis with a predominance in the right arm and conduction aphasia. T1-weighted magnetic resonance sequence of the brain showed an area of hypointensity with a high intrinsic cortical signal and hyperintensity in the T2-sequence. A Doppler velocimetric examination showed total/critical sub occlusion, suggesting an ischemic stroke.

Abstract
Introduction This study explored the impact of HIV on the functional recovery of personal activities of daily living of stroke survivors. This assisted in identifying possible implications for the rehabilitation of stroke survivors who are also HIV-positive. Method A quantitative, descriptive, longitudinal comparative research design was used to determine the change in personal activities of daily living scores of HIV-negative and HIV-positive stroke survivors from admission to 1 month after discharge. Data were collected at a rehabilitation unit using the South African Database Functional Measure. Results There was no difference in the rate and nature of functional recovery of personal activities of daily living between the two groups between admission and discharge. A difference was noticed during the period from admission to 1 month after discharge, during which the HIV-negative group continued to show improvement, while the HIV-positive group showed little improvement or a decline in personal activities of daily living scores. Conclusions While the rate and nature of functional recovery related to personal activities of daily living for HIV-positive and HIV-negative stroke survivors is similar during inpatient care, discharge planning for the HIV-positive group needs to consider the decline in personal activities of daily living functioning post discharge. Regular follow-ups and the inclusion of the stroke survivors in an outpatient treatment programme is recommended.

Abstract
Although retroviral therapy (ART) has changed the HIV infection from a fatal event to a chronic disease, treated HIV patients demonstrate high prevalence of HIV associated comorbidities including cardio/cerebrovascular diseases. The incidence of stroke in HIV infected subjects is three times higher than that of uninfected controls. Several clinical and postmortem studies have documented the higher incidence of ischemic stroke in HIV infected patients. The etiology of stroke in HIV infected patients remains unknown; however, several factors such as coagulopathies, opportunistic infections, vascular abnormalities, atherosclerosis and diabetes can contribute to the pathogenesis of stroke. In addition, chronic administration of ART contributes to the increased risk of stroke in HIV infected patients. Concurrently, experimental studies in murine model of ischemic stroke demonstrated that HIV infection worsens stroke outcome, increases blood brain barrier permeability and increases neuroinflammation. Additionally, residual HIV viral proteins, such as Trans-Activator of Transcription, glycoprotein 120 and Negative regulatory factor, contribute to the pathogenesis. This review presents comprehensive information detailing the risk factors contributing to ischemic stroke in HIV infected patients. It also outlines experimental evidence demonstrating the impact of HIV infection on stroke outcomes, in addition to possible novel therapeutic approaches to improve these outcomes.

Abstract
Introduction Stroke is a leading cause of chronic disability and death in both developing and developed countries. A significant proportion of stroke patients are human immunodeficiency virus (HIV) positive. About half of the HIV patients experience some sort of neurological deficit in their lifetimes. The exact reason for the occurrence of stroke in HIV infected patients is poorly understood. The purpose of our study is to determine the frequency of HIV among patients admitted with acute stroke. Materials and methods This cross-sectional study is conducted at a major metropolitan hospital in Karachi for six months. A total of 130 patients of stroke between the ages of 30 and 70 years of either gender were included in this study. A complete history was taken and a physical examination was performed. Each patient underwent a battery of tests that included HIV serology, lipid profile, electrocardiography (ECG), chest X-ray (posteroanterior (PA) view), and computed tomography (CT) scan of the brain. Carotid Doppler ultrasonography to assess carotid artery stenosis was also ordered. The means and standard deviations of age and cluster of differentiation 4 (CD4) cell count were calculated. The frequencies and proportions of gender, diabetes mellitus (DM), hypertension (HTN), smoking, obesity, dyslipidemia, carotid artery stenosis, and HIV status were calculated. Stratification was done by applying the chi-square test and assuming p-value ≤0.05 as significant. This helped analyze the association of age, gender, DM, HTN, smoking, obesity, dyslipidemia, and carotid artery stenosis to the frequency of HIV. Results The mean age of the study population was 55.54 ± 11.166 years. There were 39 (30%) patients <50 years of age while 91 (70%) patients were ≥50 years of age. Gender distribution showed that 86 (66.15%) patients were male, and 44 (33.85%) patients were female. Furthermore, 71 (54.62%) patients were hypertensive, 53 (40.77%) were diabetic, 62 (47.69%) were smokers, 49 (37.69%) were obese, 52 (40%) had dyslipidemia, and 77 (59.23%) had carotid artery stenosis. The frequency of HIV was noted at 24 (18.46%). The mean CD4 count was estimated at 241 ± 103.295 cells/mm3. Stratification showed a significant relationship between the frequency of HIV with only gender (p=0.01) and dyslipidemia (p=0.037). Conclusion HIV infection in patients with stroke is not uncommon. Patients who are male, younger in age, have dyslipidemia, belong to a low socioeconomic class, or have a bad sexual history are more likely to have HIV as an underlying cause of stroke. The exact pathogenesis of such a stroke and the role of antiretroviral therapy in the prevention and treatment of this group of stroke are not completely understood and need further analysis.

Abstract
In the era of effective antiretroviral therapy (ART), HIV has become a manageable disease marked by an elevated risk of non-AIDS-related comorbidities, including stroke. Rates of stroke are higher in people living with HIV (PLWH) compared with the general population. Elevated stroke risk may be attributable to traditional risk factors, HIV-associated chronic inflammation and immune dysregulation, and possible adverse effects of long-standing ART use. Tailoring stroke prevention strategies for PLWH requires knowledge of how stroke pathogenesis may differ from non-HIV-associated stroke, knowledge of long-term stroke outcomes in HIV, and accurate stroke risk assessment tools. As a result, the approach to primary and secondary stroke prevention in PLWH relies heavily on guidelines developed for the general population, with an emphasis on optimization of traditional vascular risk factors and early initiation of ART. This review summarizes existing evidence on HIV-associated stroke mechanisms and considerations for stroke prevention for PLWH.

Abstract
BACKGROUND HIV infection may affect the cardiovascular system through different physiopathological patterns. Rarely reported in HIV negative patients, aneurysms involving the carotid artery have been described for the first time in seropositive patients in 1989. AIMS In our study, we have focused on aneurysm pathology affecting carotid arteries in HIV patients, analyzing clinical and surgical presentation, management, and outcome, through a review of cases published in the literature. METHODS The MEDLINE (www.ncbi.nlm.nih.gov/pubmed) database was reviewed for "carotid artery aneurysm AND HIV OR AIDS OR immunodeficiency." RESULTS Nineteen articles including a total of 46 cases were included in our report. The mean age of patients was 30.6 ± 14.2 years; 30 patients (65.2%) were male. Aneurysms were localized in the intracranial carotid (41.3%) or extracranial artery (58%). Presenting features included symptoms due to compression of neck structures; positivity for neurological symptoms occurred in 36.9%. Patients were managed surgically in 58.7% of cases; surgical morbidity and mortality were of 22.2% and 7.4% respectively, higher for endovascular procedures. The overall mortality in treated and untreated cases was 26.1%. CONCLUSIONS Aneurysms may occur in both the extracranial and intracranial carotid artery in patients with HIV at younger age than in non-HIV patients and are linked to a high morbidity and mortality. Seropositivity must be ruled out whenever this rare vascular condition may occur in the absence of a more likely aetiology and must also be suspected in HIV patients presenting with compressive symptoms of the neck, neurological impairment or stroke.
