About COVID-19

COVID-19 is the disease caused by the new coronavirus SARS-CoV-2, which appeared in China in late 2019. Serious complications of COVID-19 are largely due to the excessive host immune response to the virus, which results in progressive pneumonia and acute respiratory distress syndrome, often requiring mechanical ventilation and critical care.1. Patients with severe COVID-19 also experience dysfunction of several organs, including acute kidney damage, liver dysfunction, heart failure, and blood abnormalities.

Although vaccination has been shown to be effective in limiting the severity of COVID-19, vaccine delays, limited vaccine access globally as well as the emergence of new SARS-CoV-2 variants have perpetuated the global pandemic. Survival rates and health system capacity can both be improved with new treatments that prevent the serious manifestations of COVID-19, such as exacerbation of pneumonia (ARDS) and AKI experienced by patients infected with SARS-CoV-2. Targeting inflammation to reduce the severity of COVID-19 is a therapeutic strategy that should not be affected by the emergence of SARS-CoV-2 variants.
