Therapeutic Approach in Colchicine-resistant Recurrent pEricarditis in Children

: Patients will continue daily treatment with anakinra up to week 12. Treatment will be then progressively tapered through the reduction of an administration of the drug per week. Reductions will be performed every 2 weeks up to discontinuation. Therefore, if a relapse does not occur, the treatment will be withdrawn at week 24.

Steroids will be progressively tapered with a reduction of 0,1-0,15 mg/kg/day of prednisone (or 5 mg in patients in treatment with the maximum dosage of 50 mg/day) from the ongoing treatment every week up to discontinuation. If a relapse does not occur, the treatment will be withdrawn in a period of time of 10 weeks.
