Background. Covid-19 continues to surprise with the variety of symptoms it causes, which is manifested both by respiratory symptoms and by the involvement of the vascular endothelium. This pathology combines the harmful effects of generalized inflammation and coagulation disorders. Objective of the study. To determine the mechanisms by which the fusion of the SARSCoV2 virus takes place with the human host cells and by which it causes disorders of the blood coagulation for the argumentation of possible treatment strategies. Material and Methods. Analysis of clinical trials performed on patients with Covid-19 and also of the literature of 2020 through the following sources: Revmed, Sciencedirect, dovepress, medrxiv, lemonde, and 10 other bibliographic sources. Results. The main actors of SARS-CoV2 infection are the following types (N354D and D364Y, V367F, W436R) of spike proteins (RBDs) that show an increased affinity for the ACE2 receptor ((ΔG) significantly reduced), which allows the virus to bind easily to the surface of the host cell. Complement system, inflammation and coagulation - are interrelated, hypoxia, being caused by respiratory dysfunction, which triggers the "cytokine storm". It includes interferon, chemokine, TNF, interleukin, which together with elevated levels of D-dimers and fibrinogen, Willebrand factor, factor VIII show a procoagulant activity. Conclusion. The most severe clinical forms are associated with anomalies in hemostasis, especially the increase of the concentration of dimers D. Early detection of these potentially predictive anomalies would contribute to an optimized prescription of anticoagulant therapy, facilitating the treatment of pat. |
