Endothelial dysfunction in COVID-19: a unifying mechanism and a potential therapeutic target. government site. Interferon-alpha or -beta facilitates SARS-CoV-2 pulmonary vascular infection by inducing ACE2. A recent study has shown that SARS-CoV-2 infection in humanized K18-hACE-2 mice activates the NLRP3 inflammasome, followed by caspase-1 and IL-1 activation[140]. COVID-19 and thyroid dysfunction: Study finds link - Medical News Today J Inflamm Res. The clinical detection of thermoregulatory impairment provides important diagnostic and localizing information in the evaluation of disorders that impair thermoregulatory pathways, including autonomic neuropathies and ganglionopathies. Kidney Int. 2021;164:6982. In line with this finding, a recent study has demonstrated that human brain microvascular endothelial cells (hBMECs) infected with SARS-CoV-2 display heightened expression of pro-inflammatory cytokines/chemokines/adhesion molecules (such as TNF-, IL-1, MCP-1, CXCL1, CXCL8, CD40, CD44, ICAM1 and VCAM1, etc) and endothelial activation [75]. Heat production and dissipation are dependent on a coordinated set of autonomic responses. Endothelial dysfunction as a primary consequence of SARS-CoV-2 Infection. Virus-induced senescence is a driver and therapeutic target in COVID-19. Therefore, supplementation with high dose intravenous vitamin C (HIVC) could hold therapeutic potential for COVID-19 patients. Syndecan-1, an important vascular component of glycocalyx released after vasculitis and injury, well correlates with the marker of coagulation (D-dimer) in particular. Kang S, Tanaka T, Inoue H, Ono C, Hashimoto S, Kioi Y, et al. Heparanase is a putative mediator of endothelial glycocalyx damage in COVID-19 - A proof-of-concept study. In vivo, SARS-CoV-2-infected K18 mice develop severe COVID-19 and endothelial dysfunction in pulmonary vessels suggested by VCAM-1 and ICAM-1 upregulation and VE-cadherin downregulation [78]. 2021;133:489507. 2021;6:e148999. The glycocalyx consists of highly sulfated proteoglycans with glycosaminoglycan side chains. Kang X, Jin D, Jiang L, Zhang Y, Zhang Y, An X, et al.

Beneficial effects of mineralocorticoid receptor pathway blockade against endothelial inflammation induced by SARS-CoV-2 spike protein. In COVID-19 patients, heart failure and myocardial injury are frequent complications, underscoring the clinical utility of SGLT2 inhibitors [128]. It has been recently reviewed that restoration of balanced effects between the RAAS and ACE2/Ang-(17)/MAS could be a promising way to ameliorate multi-organ injury associated with COVID-19 [130]. It remains to be investigated further whether TCM ameliorates COVID-19 partially by improving endothelial function. 2020;21:9712. Biomedicines. 2021;128:13236. 8600 Rockville Pike Mental status changes and core temperature distinguish potentially fatal heat stroke from heat exhaustion. In addition, reduced flow-mediated dilation (FMD, an easily obtainable method to assess endothelial dysfunction) was observed in COVID-19 patients, thus offering additional markers to serve as the proxy of endothelial cell activation [108]. Vasc Pharmacol. Graa A, Rufino I, Martins AM, Raposo S, Ribeiro HM, Marto J. Int J Pharm. Insights into endotheliopathy in COVID-19. 2020;395:14178. 2020;116:1097100. Vassiliou AG, Kotanidou A, Dimopoulou I, Orfanos SE. Correspondence to Cytokine storm and histopathological findings in 60 cases of COVID-19-related death: from viral load research to immunohistochemical quantification of major players IL-1, IL-6, IL-15 and TNF-. By using high-resolution confocal microscopy, a recent study has detected the existence of SARS-CoV-2 viral proteins within the liver sinusoidal endothelial cells (LSECs) from COVID-19 patient liver tissues[33]. Thus, metformin could be beneficial in reducing the mortality and composite outcomes in COVID-19 patients with T2DM [125]. We envisage further development of cellular models and suitable animal models mimicking endothelial dysfunction aspect of COVID-19 being able to accelerate the discovery of new drugs targeting endothelial dysfunction in pan-vasculature from COVID-19 patients. Medications to protect and/or restore the endothelial glycocalyx integrity hold great therapeutic potential for COVID-19 associated glycocalyx disruption. Increased heparanase activity and heparan sulphate level have been observed in plasma derived from COVID-19 patients [113]. Several histopathological evidence has supported direct viral infection of endothelial cells, for example, electron microscopy of kidney tissues shows the existence of endotheliitis and viral particles in ECs [52]. Combinatorial treatment of human ECs with TNF- and IFN- increased the expression of ACE2, the receptor mediating viral entry via JAK/STAT1 pathway [13]. Diabetes/hyperglycemia further exacerbate pre-existing endothelial dysfunction and hyperinflammation in COVID-19 patients. Katsoularis I, Fonseca-Rodrguez O, Farrington P, Lindmark K, Fors Connolly AM. However, there are also reports showing that ACE2 expression is absent from human ECs. These results suggest that statins can be exploited to treat COVID-19 patients by mitigating endotheliopathy [45, 121]. These effects were blocked by soluble glycoprotein 130, ruxolitinib, and STAT1/3 depletion. In addition to the spike protein, nucleocapsid protein of SARS-CoV-2 can also promotes endothelial activation via TLR2/NF-B and MAPK signaling pathways. S protein treatment of HAECs leads to increased secretion of inflammatory molecules (IL-6, MCP-1 and IL-18) and PAI-1, which can be attenuated by minerocorticoid receptor antagonists [56]. 2021;9:639.

Because each symptom can be traced to the autonomic nervous system and its dysfunction, a platform for investigation is clear. Endothelial integrity is essential for maintaining the pulmonary capillary-alveolar barrier and lung homoeostasis. A recent study has demonstrated that SARS-CoV-2 infection increased superoxide anion production, and mitochondrial DNA (mtDNA) release, leading to the activation of TLR9 and NF-B, which orchestrates the expression of inflammatory genes[94]. Employing mechanical ventilation techniques on venovenous extracorporeal membrane oxygenation (VV ECMO .

Fluvoxamine vs placebo and clinical deterioration in outpatients with symptomatic COVID-19: a randomized clinical trial. Vitamin C consumption significantly reduces mortality risk with COVID-19 patients [157]. 2021;10:e1350. Furthermore, spike protein S1 receptor-binding domain (S1-RBD) infection in mouse brain microvascular ECs induced the degradation of endothelial junctional proteins (VE-Cadherin, junctional adhesion molecule-A, Connexin-43 and PECAM-1), thereby impaired endothelial barrier function and caused vascular leakage and endotheliitis in COVID-19 patients [57, 58]. The primary pharmacological target of heparin could possibly be the endothelial glycocalyx, which is an important microstructure in endothelial cells, essential for maintaining vascular homeostasis by regulating vascular tone, barrier integrity, preventing leukocyte adhesion and thrombosis.

Article Am J Respir Crit Care Med. A recent study has shown the possible involvement of EndoMT in COVID-19. COVID-19 and erectile dysfunction: endothelial dysfunction and beyond. SARS-CoV-2 crosses the blood-brain barrier accompanied with basement membrane disruption without tight junctions alteration. However, compromised glycocalyx integrity promotes S protein/ACE2 interaction and facilitates viral entry [68]. Consistent with this notion, elevated level of C3a in severe COVID-19 patients induced the activation of CD16+ cytotoxic T cells which promotes endothelial injury and the release of monocyte chemoattractant proteins as well as neutrophil activation [96]. 2021;47:3929.
