Revision of possible pathophysiologic mechanisms 2020-06-02 .txt text/plain 5143 262 39 RESULTS: The pathophysiology of the disease is multifactorial: association with innate immune response, hypercoagulability state, lung tissue damage, neurological and/or gastrointestinal tract involvement, monocytic/macrophage activation syndrome, culminating in exaggerated cytokine secretion, called "cytokine storm", which leads to worsening and death. Until the present day, the cardinal points in severe COVID-19 are upregulated innate immune human response; hypercoagulable state; polymorphous clinical manifestations, due to pulmonary tissue damage, neurological and/ or gastrointestinal tract involvement; and fatal outcome in severe cases of macrophage activation syndrome-like (MAS) [102] . Excessive activation of inflammatory mediators creating a "cytokine storm", leading to damage to the endothelium; formation of multiple thromboses in the microvasculature of the skin; changes in the cellular component of immunity with activation of the complement system, as well as, the possibility of direct entry of SARS-CoV-2 entry via receptor ACE2 and protease TMPRSS2 in the human endothelial cell in dermal blood vessels cannot be excluded such as possible mechanisms if the possibility of virus circulation in the blood is proved. ./cache/cord-265813-2onv9mvl.txt ./txt/cord-265813-2onv9mvl.txt
