Case ReportsCerebral Microhemorrhage and Purpuric Rash in COVID-19: The Case for a Secondary Microangiopathy.
Since the emergence of Coronavirus Disease 19 (COVID-19) pandemic, multiple neurologic complications in infected patients have been reported. Despite these reports, the mechanism of COVID-19 nervous system injury is not well understood. We report the case of a COVID-19 patient with diffuse microhemorrhages on brain MRI, positive anticardiolipin antibodies, and purpuric rash with biopsy showing a thrombotic vasculopathy, all features suggestive of secondary microangiopathy. ⋯ A 69-year-old male with history of hypertension, chronic kidney disease, and hypothyroidism presented with one week of dyspnea, cough, diarrhea, and fevers. Chest x-ray demonstrated bibasilar consolidations and nasopharyngeal reverse transcriptase polymerase chain reaction confirmed SARS-CoV-2 infection. He had subsequent respiratory decline requiring intubation the day after admission. He developed a truncal morbilliform rash and diffuse purpura, a biopsy of which showed small dermal blood vessels with intraluminal microthrombi consistent with thrombotic vasculopathy. He was found to have elevated aCL IgM and IgG and equivocal lupus anticoagulant study. Brain MRI obtained for persistent encephalopathy showed innumerable areas of susceptibility weighted imaging changes throughout the bilateral juxtacortical white matter, corpus callosum, basal ganglia, and brainstem, as well as multiple small areas of FLAIR hyperintensities, consistent with microhemorrhage DISCUSSION: While there have been several reported cases of neurologic manifestations of COVID-19, the pathophysiology may not be related to neurotropism of the virus itself. The new development of antiphospholipid antibodies and thrombotic vasculopathy in dermal blood vessels in this patient suggest a secondary microangiopathy potentially related to a virally-induced inflammatory state.

Review Multicenter Study Comparative StudyCerebral venous thrombosis in Argentina: clinical presentation, predisposing factors, outcomes and literature review.
Cerebral venous thrombosis (CVT) is a rare medical condition that primarily affects young adults. The clinical spectrum is broad and its recognition remains a challenge for clinicians. Limited information is available on CVT in Argentina. Our goal was to report the results of the first National registry on CVT in Argentina and to compare clinical presentation, predisposing factors and outcomes with other international registries. ⋯ Participants in the first ANR-CVT had a low mortality and disability at 90 days. Clinical and radiological characteristics were similar to CVT from other international registries with a higher prevalence of cancer. There was a high variability in treatment adherence to guidelines as reflected by anticoagulation rates (range 54.5%-100%) at discharge.

Multicenter Study Comparative StudyCall to Action: SARS-CoV-2 and CerebrovAscular DisordErs (CASCADE).
The novel severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2), now named coronavirus disease 2019 (COVID-19), may change the risk of stroke through an enhanced systemic inflammatory response, hypercoagulable state, and endothelial damage in the cerebrovascular system. Moreover, due to the current pandemic, some countries have prioritized health resources towards COVID-19 management, making it more challenging to appropriately care for other potentially disabling and fatal diseases such as stroke. The aim of this study is to identify and describe changes in stroke epidemiological trends before, during, and after the COVID-19 pandemic. ⋯ The proposed study will potentially enable us to better understand the changes in stroke care protocols, differential hospitalization rate, and severity of stroke, as it pertains to the COVID-19 pandemic. Ultimately, this will help guide clinical-based policies surrounding COVID-19 and other similar global pandemics to ensure that management of cerebrovascular comorbidity is appropriately prioritized during the global crisis. It will also guide public health guidelines for at-risk populations to reduce risks of complications from such comorbidities.
