Within the DS group, IL-6 and ferritin were associated with admission SOFA score (p<0.001 for both), ICU admission (p<0.001 for both) & mortality (IL-6: p = 0.005 & ferritin: p = 0.02); both biomarkers discriminated survivors and non-survivors at 48 hours and all patients who died from DS had pre-mortem ferritin ≥100,000ng/ml. Here, IL6 is linked to Dravet syndrome.
