Infliximab
Infliximab will be administered as a single IV dose of 10 mg/kg over 2 hours. Infliximab: Infliximab will be administered as a single IV dose of 10 mg/kg over 2 hours.
Methylprednisilone (steroids)
Methylprednisilone (steroids) will be administered as 2 mg/kg IV or orally divided every 12 hours. At the time of hospital discharge the patient will be given a steroid taper that will take at least 3 weeks to complete. Methylprednisolone: Methylprednisilone (steroids) will be administered as 2 mg/kg IV or orally divided every 12 hours. At the time of hospital discharge the patient will be given a steroid taper that will take at least 3 weeks to complete.
Anakinra
Anakinra will be administered at a dose of 8 mg/kg/day IV or SQ with 100 mg every 6 hours as the max dose. This is discontinued with a taper during the hospitalization over 2-4 days once a patient is stable with significantly improved clinical course and laboratory profile.
