Furthermore, drawing from the experience of adult COVID-19 patients' management (109), corticosteroid may be considered in pediatric patients, based on expert opinions, if three of the following four indications are met: 1 fever of more than 38.5°C, lasting for at least 3 days; 2 CRP ≥30 mg/L; 3 serum ferritin ≥1,000 μg/L; 4 diffused infiltrative changes documented in both lungs. Here, CRP is linked to COVID-19.
