Covid-19 disease MESHD is caused by SARS Cov-2 virus. Despite its high transmissibility TRANS, the CFR (Case Fatality Rate) of COVID-19 seems to be lower than the SARS (9,5%) and MERS (34,4%) ones93 , but higher than the influenza one (0-1%)94,95 . The disease is asymptomatic MESHD asymptomatic TRANS or paucisymptomatic in most of the patients, although in few cases it can be characterized by serious complications. The main causes of hospitalization in intensive care are represented by ALI ( Acute Lung Injury MESHD), ARDS (Acute Respiratory Distress HP Syndrome MESHD), cardiovascular problems and coagulopathies (diffuse thrombosis MESHD, microthrombosis, embolisms MESHD, myocarditis MESHD myocarditis HP, arrhytmias, heart failure MESHD, stroke MESHD stroke HP)96-98, acute nephropathy99,100 and encephalopathies101. The virus presence in the vascular wall can cause endotheliitis, which triggers the process of diffuse coagulation that can lead to a worsening of the systemic inflammation MESHD. The exaggerated inflammatory response seems to be connected with the development of ARDS, MOF ( Multiple Organ Failure MESHD) and coagulopathies102-107.
