A Potential Role of the CD47/SIRPalpha Axis in COVID-19 Pathogenesis
Curr Issues Mol Biol. 2021 Sep 22;43(3):1212-1225. doi: 10.3390/cimb43030086.ABSTRACTThe coronavirus SARS-CoV-2 is the cause of the ongoing COVID-19 pandemic. Most SARS-CoV-2 infections are mild or even asymptomatic. However, a small fraction of infected individuals develops severe, life-threatening disease, which is caused by an uncontrolled immune response resulting in hyperinflammation. However, the factors predisposing individuals to severe disease remain poorly understood. Here, we show that levels of CD47, which is known to mediate immune escape in cancer and virus-infected cells, are elevated in SARS-CoV-2-infected ...

SARS-CoV-2: Pathogenic Mechanisms and Host Immune Response
Adv Exp Med Biol. 2021;1313:99-134. doi: 10.1007/978-3-030-67452-6_6.ABSTRACTSevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an enveloped, positive-sense RNA coronavirus responsible for the COVID-19 pandemic. Since December 2019, coronavirus disease 2019 (COVID-19) has affected more than 127 million people, 2.7 million deaths globally (as per WHO dashboard, dated 31 March, 2020), the virus is capable of transmitting from human to human via inhalation of infected respiratory droplets or aerosols or contact with infected fomites. Clinically, patients with COVID-19 present with severe respiratory distress synd...

Cerebrovascular Accident and SARS-CoV-19 (COVID-19): A Systematic Review
Discussion: The data suggest SARS-CoV-2 is a risk factor for developing stroke, particularly in patients with hypertension and diabetes. Furthermore, the younger average age of stroke in patients with SARS-CoV-2, particularly those patients with zero identifiable preexisting conditions, creates high suspicion that SARS-CoV-2 is an independent risk factor for development of stroke; however, this cannot yet be proven without comparable control population. The data suggest the risk of developing CVA in the setting of COVID-19 infection is not dependent upon severity of illness. Continued studies must be done to understand the...

Doxycycline for community treatment of suspected COVID-19 in people at high risk of adverse outcomes in the UK (PRINCIPLE): a randomised, controlled, open-label, adaptive platform trial
Lancet Respir Med. 2021 Jul 27:S2213-2600(21)00310-6. doi: 10.1016/S2213-2600(21)00310-6. Online ahead of print.ABSTRACTBACKGROUND: Doxycycline is often used for treating COVID-19 respiratory symptoms in the community despite an absence of evidence from clinical trials to support its use. We aimed to assess the efficacy of doxycycline to treat suspected COVID-19 in the community among people at high risk of adverse outcomes.METHODS: We did a national, open-label, multi-arm, adaptive platform randomised trial of interventions against COVID-19 in older people (PRINCIPLE) across primary care centres in the UK. We included peo...

SARS ‐CoV‐2 and hypertension
The objective of this review is to give an overview of the pathophysiological effects of the Coronavirus Disease 2019 (COVID-19) in relation to hypertension (HT), with a focus on the Renin –Angiotensin–Aldosterone System (RAAS) and the MAS receptor. HT is a multifactorial disease and a public health burden, as it is a risk factor for diseases like stroke, coronary artery disease, and heart failure, leading to 10.4 million deaths yearly. Blood pressure is regulated by the RAAS. The system consists of two counter-regulatory axes: ACE/ANG-II/AT1R and ACE2/ANG-(1-7)/MAS. The main regulatory protein in balancing the RAAS is...

Neurological complications in pediatric patients with SARS-CoV-2 infection: a systematic review of the literature
ConclusionsOur research highlights the large range of neurological manifestations and their presumed pathogenic pathways associated with SARS-CoV-2 infection in children. Nervous system involvement could be isolated, developing during COVID-19 or after its recovery, or arise in the context of a MIS-C. The most reported neurological manifestations are cerebrovascular accidents, reversible splenial lesions, GBS, benign intracranial hypertension, meningoencephalitis; ADEM is also a possible complication, as we observed in our patient. Further studies are required to investigate all the neurological complications of SARS-CoV-2...

Anesthetic Management for Endovascular Treatment of Stroke in Patients With Coronavirus Disease 2019: A Case Series
A significant number of patients with coronavirus disease 2019 develop strokes with large vessel obstructions that may require endovascular treatment for revascularization. Our series focuses on periprocedural issues and the anesthetic management of these patients. We analyzed medical records of 5 patients with positive reverse transcription polymerase chain reaction tests for severe acute respiratory syndrome coronavirus 2 during their hospitalization who underwent endovascular treatment at our hospital between March and mid-June 2020. We found that our patients were different from the typical patients with ischemic strok...

Pathogeny of cerebral venous thrombosis in SARS-Cov-2 infection: Case reports
We describe 2 cases of women admitted during the spring of 2020 for intracranial hypertension signs, in stroke units in Great-east, a French area particularly affected by COVID-19 pandemia. Diagnoses: Cerebral imaging revealed extended CVT in both cases. The first case described was more serious due to right supratentorial venous infarction with hemorrhagic transformation leading to herniation. Both patients presented typical pneumonia due to SARS-Cov-2 infection, confirmed by reverse transcription polymerase chain reaction on a nasopharyngeal swab in only one. Interventions: The first patient had to undergo ...

Neurological Complications of the COVID-19 Pandemic: What Have We Got So Far?
Adv Exp Med Biol. 2021;1321:21-31. doi: 10.1007/978-3-030-59261-5_2.ABSTRACTThe recently emerged coronavirus named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causal agent of COVID-19, is the newest threat to human health. It has already infected more than 54.5 million people worldwide, currently leading to more than 1.3 million deaths. Although it causes a mild flu-like disease in most patients, lethality may increase to more than 20% in elderly subjects, especially in those with comorbidities, like hypertension, diabetes, or lung and cardiac disease, and the mechanisms are still elusive. Common symp...
