Corticosteroids use
Methylprednisolone was used for each of the 55 children with corticosteroids, at an initial median (IQR) dose of 2 (1.9-2) mg/kg/day. The median time (IQR) between hospital admission and initiation of corticosteroids was 5.5 (4-7) days. When corticosteroids were initiated, children were febrile since 9 (IQR 8-11) days. The fever ceased in a median (IQR) of 0 (0-1) day after corticosteroids initiation. Three patients required more than 1 course of corticosteroids because of fever recurrence when corticosteroids were ceased. The median duration (IQR) of corticosteroid therapy was 8.5 (4-13.3) days.
