The world has been facing a dreadful situation due to the spread of the Severe Acute Respiratory Syndrome–Coronavirus-2 (SARS-CoV-2) (1). However, neither confirmed effective antiviral medications nor vaccines are available to deal with this emer-gency (2). Many reports have suggested that it is the cytokine storm in COVID-19 that leads to acute respiratory distress syndrome (ARDS) (3). The cytokine storm in COVID-19 refers to the fact that a variety of cytokines are rapidly produced after viral infections (4). In addition, such a cytokine storm induces hypoxia, and direct viral infection can cause cellular damage. Multiorgan damage and injury have been concomitant with COVID-19, and can be observed more in patients with a more severe form of the disease (5).
