HIV-associated multiple intracranial aneurysms and stroke in an adult patient: successful treatment with a combination of glucocorticoid and antiviral agents
AbstractA 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...

A case of ischemic stroke secondary to varicella-zoster virus meningoencephalitis
AbstractVaricella-zoster virus (VZV) lurks in cranial nerves and other brain ganglias after infection. Because middle cerebral artery (MCA) receives the ipsilateral trigeminal ganglia afferent innervations, the reactivated VZV infects the adventitia and intima of cerebral artery wall probably through this way and causes vascular inflammation, finally resulting in artery remodeling, vessel occlusion, and ischemia. In fact, there is a growing clinical recognition that there is an association between VZV reactivation and subsequent stroke. Here, we showed a case of ischemic stroke secondary to varicella-zoster virus meningoen...

Susac syndrome complicating a SARS-CoV-2 infection
We present a case of a 40-year-old man diagnosed with Susac syndrome after COVID-19, presenting with acute sensorineural hearing loss, encephalopathy, a splenial “snowball-like” lesion, and branch retinal artery occlusions with distal arterial wall hyperintensity. Although the pathophysiology of Susac syndrome remains unclear, this case is in line with the ongoing debate about the influence of SARS-CoV-2 on the human immune system. Corticosteroid treatme nt was initiated, followed by two treatments with rituximab, with clinical improvement of the symptomatology. Maintenance treatment currently consists of mycophenolic ...

A case-based systematic review on the SARS-COVID-2-associated cerebrovascular diseases and the possible virus routes of entry
AbstractSevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sparked a global pandemic that continues to affect various facets of human existence. Many sources reported virus-induced acute cerebrovascular disorders. Systematically, this paper reviews the case studies of COVID-19-related acute cerebrovascular diseases such as ischaemic stroke, intracerebral hemorrhage, and cerebral sinus thrombosis. We also spoke about how SARS-CoV-2 can infect the brain and trigger the aforementioned disorders. We stated that SARS-CoV-2 neuroinvasion and BBB dysfunction could cause the observed disorders; however, further research ...

Potential mechanisms of cerebrovascular diseases in COVID-19 patients
AbstractSince the outbreak of coronavirus disease 2019 (COVID-19) in 2019, it is gaining worldwide attention at the moment. Apart from respiratory manifestations, neurological dysfunction in COVID-19 patients, especially the occurrence of cerebrovascular diseases (CVD), has been intensively investigated. In this review, the effects of COVID-19 infection on CVD were summarized as follows: (I) angiotensin-converting enzyme 2 (ACE2) may be involved in the attack on vascular endothelial cells by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), leading to endothelial damage and increased subintimal inflammation, wh...

Viral protein R polymorphisms in the pathogenesis of HIV-associated acute ischaemic stroke: a case –control study
AbstractHIV-1 viral proteins have been implicated in endothelial dysfunction, which is a major determinant of ischaemic stroke risk in HIV-infected individuals. Polymorphisms in HIV-1 viral protein R (Vpr) may alter its potential to promote endothelial dysfunction, by modifying its effects on viral replication, reactivation of latent cells, upregulation of pro-inflammatory cytokines and infection of macrophages. We analysed Vpr polymorphisms and their association with acute ischaemic stroke by comparing Vpr signature amino acids between 54 HIV-infected individuals with acute ischaemic stroke, and 80 age-matched HIV-infecte...

Elevated serum substance P during simian varicella virus infection in rhesus macaques: implications for chronic inflammation and adverse cerebrovascular events
AbstractVaricella and zoster, produced by varicella-zoster virus (VZV), are associated with an increased risk of stroke that may be due to persistent inflammation and hypercoagulability. Because substance P is associated with inflammation, hypercoagulability, and atherosclerotic plaque rupture that may contribute to increased stroke risk after VZV infection, we measured serum substance P in simian varicella virus –infected rhesus macaques. We found significantly increased and persistent serum substance P concentrations during varicella and zoster compared with pre-inoculation, supporting the hypothesis that VZV-induced i...

Neurological injuries in COVID-19 patients: direct viral invasion or a bystander injury after infection of epithelial/endothelial cells
AbstractA subset of patients withcoronavirus 2 disease (COVID-19) experience neurological complications. These complications include loss of sense of taste and smell, stroke, delirium, and neuromuscular signs and symptoms. The etiological agent of COVID-19 isSARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), an RNA virus with a glycoprotein-studded viral envelope that uses ACE2 (angiotensin-converting enzyme 2) as a functional receptor for infecting the host cells. Thus, the interaction of the envelope spike proteins with ACE2 on host cells determines the tropism and virulence ofSARS-CoV-2. Loss of sense of tast...

Herpes simplex virus 2 vasculitis as cause of ischemic stroke in a young immunocompromised patient
We report a case of a young woman with a left middle cerebral artery (MCA) ischemic stroke. The patient had history of HIV-1 infection, with periods of therapeutic non-compliance. Initial computed tomography (CT) imaging studies showed stenosis of the M1 segment of the left MCA, and magnetic resonance imaging (MRI) confirmed infarction of the MCA territory. Serial transcranial Doppler ultrasound revealed progressive occlusion of the MCA and stenosis of the left anterior cerebral artery. Systemic investigation for other causes of stroke was normal. Lumbar puncture revealed a mildly inflammatory cerebrospinal fluid, and HSV-...
