Kang S Boulanger CM Quillard T Should a stray thrombus form on the intimal lining of a blood vessel, the endothelial cells can express plasminogen activators that can boost endogenous fibrinolysis.10 Endothelial cells can produce both tissue-type plasminogen activator (tPA) and urokinase plasminogen activator (uPA),11 and, through the release of nitric oxide by platelet-derived substances, inhibit platelet function and increase local blood flow to flush away an evolving clot. The lungs from patients with Covid-19 also showed distinctive vascular features, consisting of severe endothelial injury associated with the … Under physiological circumstances, the endothelial gateway selectively regulates endothelial permeability and fosters vascular integrity. Glucocorticoids and colchicine exert generalized anti-inflammatory actions and show promise in the treatment of patients with advanced COVID-19.53,54 Statins have direct anti-inflammatory effects beyond their lipid-lowering actions, mediated by inhibition of prenylation of small G proteins or induction of transcription factors such as KLF-2 that promote homeostatic endothelial functions.55Non-randomized treatment with statins yielded preliminary retrospective evidence of improved outcomes in COVID-19, as well as reductions in biomarkers of inflammation.56, Targeted inhibition of cytokines, major effectors of endothelial activation, represents a more focused approach than generalized anti-inflammatory agents. , Navarro S , Lundstrom A , Laplanche S , Persson O , Stark H Members of the selectin class of leucocyte adhesion molecules slow the transit of blood leucocytes past the endothelial surface by mediating rolling of these cells. , Ma X Venous thrombosis and pulmonary embolism also commonly complicate COVID-19, pathological processes that clearly depend on deranged endothelial functions.49 NETs induced by inflammatory cytokines activate procoagulant functions of endothelial cells, and contribute to coagulation and the formation of the typically tightly organized thrombi in COVID-19.

The elevated expression of these endothelial–leucocyte adhesion molecules depends upon irritative stimuli, principally proinflammatory cytokines such as interleukin-1α (IL-1α) and IL-1β or tumour necrosis factor-α (TNF-α). , Bai L Downstream of IL-1, antibodies that interfere with IL-6 signalling have also shown signs of benefit in some but not all preliminary studies, although this as well as other anticytokine therapies may entail an increased risk of superinfection.59,60 Other anti-IL-6 strategies also warrant consideration.61 Upon inflammatory stimulation, vascular endothelial and smooth muscle cells produce large amounts of IL-6; thus, blocking signalling of this distal mediator can limit local vascular amplification of inflammatory responses, including in the lung.

SUMMARY: Coronavirus disease 19 (COVID-19) is a pandemic originating in Wuhan, China, in December 2019. , Wang D Early reports suggest that there are neurologic manifestations of COVID-19, including acute cerebrovascular disease. As a result of endothelial activation and ED, the levels of pro-inflammatory cytokines (interleukin -1, interleukin-6 (IL-6), and tumor necrosis factor-α), chemokines (monocyte chemoattractant protein-1), von Willebrand factor (vWF) antigen, vWF activity, and factor VIII are elevated. , Soehnlein O , Haynes R , Warner SJC , Chen M-M , Giannopoulos G In view of the central role of inflammatory mediators in the complications of COVID-19, anti-inflammatory therapies merit careful clinical evaluation. , Konkle BA , Drosopoulos JHF 2020 Nov 21;9(11):3746. doi: 10.3390/jcm9113746. , Binder C The left side of the diagram depicts a resting endothelial monolayer with the endothelial cells of squamous morphology resting on an intact basement membrane. , Emberson J , Shvartz E , Renaud S , Maqsood Z , eds. COVID-19 can cause symptoms that go well beyond the lungs, from strokes to organ failure. , Seelig J Small, non-randomized studies of a recombinant form of the endogenous IL-1 receptor antagonist, anakinra, have furnished sufficient encouragement to merit further definitive investigation.57,58 Anakinra blocks both IL-1α and IL-1β, and requires daily dosing. Alterations in endothelial thrombotic/fibrinolytic balance can predispose to thrombosis not only in the pulmonary circulation but also in peripheral veins and arteries of the cerebral circulation, causing unheralded strokes in apparently healthy young people and doubtless contributing to the local and patchy embarrassment of blood flow in ‘COVID toes’ that probably represent microvascular dysfunction with tissue ischaemia. , Liu PP E-selectin (CD62E) causes polymorphonuclear leucocytes to tarry on the endothelial surface. , Lei F Published on behalf of the European Society of Cardiology.
