thermoregulatory dysfunction in covid 19

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]. Neurological implications of COVID-19: role of redox imbalance and mitochondrial dysfunction. 2022;52:e13726. Moreover, supernatant from virus-infected cells can trigger neutrophil extracellular trap formation and platelet activation [88]. Melatonin drugs inhibit SARS-CoV-2 entry into the brain and virus-induced damage of cerebral small vessels. The IL-1, IL-6, and TNF cytokine triad is associated with post-acute sequelae of COVID-19.

Maldonado F, Morales D, Daz-Papapietro C, Valds C, Fernandez C, Valls N, et al. Therefore, primary endothelial cell senescence or secondary senescence caused by SRAS-CoV-2 infected non-ECs can be exploited as a new therapeutic target for ameliorating COVID-19 associated endotheliitis [90]. 2022;145:15035. Endothelial contribution to COVID-19: an update on mechanisms and therapeutic implications. 3). Front Immunol. Respir Med. Mechanistically, L-SIGN interacted with high-mannose-type N-glycans on the receptor-binding domain of SARS-CoV-2 spike protein in a Ca2+-dependent manner [33]. SARS-CoV-2 causes ACE/ACE2 balance disruption and RAAS activation, which leads ultimately to COVID-19 progression, especially in patients with comorbidities, such as hypertension, diabetes mellitus, and cardiovascular disease. Cell Rep Med. 2020;24:422. The effect of glucocorticoids on COVID-19 might be multifactorial, and their endothelium-stabilizing properties by direct activation of endothelial glucocorticoid receptors to block production of IL-6 and VEGF might be the main operating mechanisms [19]. Ni W, Yang X, Yang D, Bao J, Li R, Xiao Y, et al. Biomedicines. Pulmonary capillary endothelium provides a fertile soil for viral entry, replication, thereby facilitating viral entry to the circulating blood [19, 20]. Coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2 infection represents an ongoing public health burden leading to extensive morbidity and mortality worldwide [1]. In addition, mtDNA release also increased vascular reactivity to ET1[94]. Article Circ Res. 2022. https://doi.org/10.1164/rccm.202207-1258ED. Klouda T, Hao Y, Kim H, Kim J, Olejnik J, Hume AJ, et al. Management includes warming measures, hydration, and cardiovascular support. Thermoregulatory dysfunction is defined as significant loss of a person's capacity to control body temperature, and the medical conditions which result in the person's health and bodily function being seriously affected when exposed to extremes of environmental temperatures. 2021;41:176073. Of translational relevance, several candidate drugs which are endothelial protective have been shown to improve clinical manifestations of COVID-19 patients.

Hyperthermia, defined as a core temperature of >40.5C, may present with sweating, flushing, tachycardia, fatigue, lightheadedness, headache, and paresthesia, progressing to weakness, muscle cramps, oliguria, nausea, agitation, hypotension, syncope, confusion, delirium, seizures, and coma. Like other types of organ injury, SARS-CoV-2 infection causes AKI by both direct and indirect mechanisms, including endotheliitis, thrombosis and glucolipid derangement. It is well-recognized that patients with type 2 diabetes mellitus (T2DM) present with increased COVID-19 severity and poorer clinical outcomes compared with non-diabetic subjects [122]. J Med Virol. SARS-CoV-2 productively infects human brain microvascular endothelial cells. Google Scholar. Interestingly, live SARS-CoV-2 virus and sera from COVID-19 patients, but not dead virus or spike protein triggers increased endothelial permeability [20, 23]. 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]. In another translational study, treatment of human pluripotent stem cell-derived endothelial cells (hECs) with SARS-CoV-2 leads to enriched gene program involved in immunity, inflammation and viral response (such as TNF-, IFNs and NF-B signaling pathway). Direct activation of endothelial cells by SARS-CoV-2 nucleocapsid protein is blocked by simvastatin. Recent randomized clinical trials revealed that treatment with fluvoxamine (a selective serotonin reuptake inhibitors, SSRI) reduced the need for COVID-19 hospitalization, reduced mortality and improved outcome over 15 days [148,149,150].

Schimmel L, Chew KY, Stocks CJ, Yordanov TE, Essebier P, Kulasinghe A, et al. Infection with various types of viruses, including SARS-CoV-2, can trigger endothelial senescence. It is possible that these cytokines will disrupt the integrity of various types of junctional proteins, including VE-cadherin, ZO-1, -catenin and gap junction proteins. Analysis of ACE2 expression in autopsy tissues indicates that high expression of ACE2, transmembrane protease serine 2 (TMPRSS2) and associated endotheliitis in capillaries but less in arterioles/venules from COVID-19 patients, compared with COVID-19-free subjects. It has been increasingly appreciated that COVID-19 is not only an infectious disease involving the lung; but also, a vascular disease affecting extrapulmonary organs [174]. Till now, several TCM have shown good therapeutic effects in COVID-19, such as Lianhua Qingwen, Xuebijing Injection, Shuanghuanglian, Jinyinhua and Qingfei Paidu Decoction [161,162,163,164]. Hemil H, de Man AME. Crit Care (Lond, Engl). 2021;95:e0139621. Front Med. 2022;75:103812. 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]. Mechanistically, fluvoxamine is a sigma-1 receptor (S1R) agonist which, on the one hand, reduces the expression of IL-6, while increasing that of eNOS. 2020;7:559811. Cardiovascular dysfunction in COVID-19: association between endothelial cell injury and lactate. Although current pharmacotherapies against acute and post-acute COVID-19 mainly centered on blocking viral replication and limiting inflammation/inflammasome activation, it is likely that novel therapeutic approaches targeting endothelial dysfunction could represent a promising strategy to cardiovascular sequelae in COVID-19 convalescent patients [6] in light of elevated circulating level of biomarker soluble P-selectin in COVID-19 convalescent donors compared to healthy controls [175]. 01 May 2023 01:18:34 4 and 5) [101]. the best experience, we recommend you use a more up to date browser (or turn off compatibility mode in Endothelial to mesenchymal transition: a precursor to post-COVID-19 interstitial pulmonary fibrosis and vascular obliteration? 2021: 1-15. Pawlos A, Niedzielski M, Gorzelak-Pabi P, Broncel M, Woniak E. COVID-19: direct and indirect mechanisms of statins. Since the outbreak of COVID-19 in early 2020, emerging evidence has demonstrated endothelial dysfunction as the unifying and central mechanism of COVID-19 [6]. Mounting evidence suggests that SARS-CoV-2 infection leads to multiple instances of endothelial dysfunction, including reduced nitric oxide (NO) bioavailability, oxidative stress, endothelial injury, glycocalyx/barrier disruption, hyperpermeability, inflammation/leukocyte adhesion, senescence, endothelial-to-mesenchymal transition (EndoMT), hypercoagulability, thrombosis and many others. Xing D, Liu Z. Thus, the endothelium is regarded as the Achilles heel in COVID-19 patients [8]. Statins are prescribed as the first-choice treatment for patients with hypercholesterolemia and coronary artery disease due to their lipid-lowering and pleiotropic anti-inflammatory, antioxidant, anti-thrombotic and immune-modulatory effects. These effects were blocked by soluble glycoprotein 130, ruxolitinib, and STAT1/3 depletion. Large-scale clinical trials are warranted to evaluate whether the use of SGLT2 inhibitors can reduce the mortality and hospitalizations for heart failure in COVID-19 patients with or without T2DM.

Several large-scale clinical trials have suggested that glucocorticoid drug dexamethasone treatment is beneficial for COVID-19 patients [134]. Unauthorized use of these marks is strictly prohibited. The .gov means its official. However, pre-treatment of ECs with losartan (belonging to ARB) and lisinopril (belonging to ACEI), fail to affect the susceptibility of hEC to SARS-CoV-2 infection [131].

Endothelial dysfunction is generally defined as decreased NO bioavailability and an increase in vasoconstrictory substances (such as endothelin-1 (ET1), angiotensin II (AngII) and many others).
