All patients presented in a hyperinflammatory state characterized by elevated C-reactive protein (median, 113.81 mg/L ± 84.22), serum ferritin (median, 389.25 ng/mL; IQR, 185.00–593.00), interleukin-6 (median, 15.39 pg/mL; IQR, 11.50–65.60), and lymphopenia (median, 1570.00 cells/μL; IQR, 1050.00–2440.00). This evidence concerns the gene IL6 and lymphopenia.
