The clinical spectrum of COVID-19 can be very heterogeneous: from mild flu-like symptoms, to the form with severe pulmonary impairment (dyspnoea, tachypnoea, PaO2 / FiO2 ratio below 300 at arterial blood gas sampling, pulmonary infiltrates covering more than 50% of the respiratory surface); up to 5% of patients tend to rapidly develop acute respiratory distress syndrome (ARDS) with or without acute cardiac damage, underlying a phase of systemic hyperinflammation (cytokine storm) that may result in shock, multi-organ failure and death
