Brief summary
The COVID-19 pandemic has had a dramatic effect in public health worldwide. In Brazil, there have been more than 2 million confirmed cases and over 75,000 deaths since February 26, 2020. Based on reports of a hyperinflammatory state associated with COVID-19, the use of immunosuppressive drugs may be efficacious in the treatment of this disease. JAK inhibitors have been shown to harness inflammation in a number of different pathologic conditions. The aim of the present study is to evaluate the efficacy and safety of JAK inhibitor ruxolitinib in patients with acute respiratory distress syndrome due to COVID-19.
