AbstractThe novel coronavirus infectious disease (COVID-19) has rapidly spread and poses a great challenge to researchers, both in elucidating its pathogenic mechanism and developing effective treatments. It has been recently proposed that COVID-19 is an endothelial disease. Indeed, the COVID-19 virus binds to angiotensin-converting enzyme type 2 (ACE2), which is expressed in endothelial cells. ACE2 could be implicated in the production of reactive oxygen species (ROS) caused by endothelial dysfunction due to viral damage. Consequently, oxidative stress could prime these cells to acquire a pro-thrombotic and pro-inflammatory phenotype, predisposing patients to thromboembolic and vasculitic events and to disseminated intravascular coagulopathy (DIC). This implies a pivotal role played by oxygen in the pathogenetic mechanism of COVID-19 disease, in that its availability would tune the oxidant state and consequent damage.© Royal College of Physicians 2020.
