IL17A and acute respiratory distress syndrome: Among the critically ill COVID-19 patients, ICU admission IL-17 levels did not differ between survivors and non-survivors (0.73 pg/mL vs. 0.69 pg/mL, p > 0.05), but tended to be higher in patients with COVID-19-inflicted ARDS requiring invasive mechanical ventilation compared to those who were not intubated (0.86 pg/mL vs. 0.08 pg/mL, p = 0.08).
