Infliximab in the treatment of adult Still's disease refractory to conventional therapy

Clin Exp Rheumatol. May-Jun 2001;19(3):329-32.


In this study we evaluated the efficacy of Infliximab in the treatment of adult Still's disease (ASD) refractory to conventional therapy. Three patients with chronic and active ASD unresponsive to corticosteroids and methotrexate were given intravenous Infliximab infusions at a dosage of 3 mg/kg at weeks 0, 2, 6 and then once every 8 weeks. Methotrexate was maintained in all cases at a dosage of 15 mg/week, whereas the prednisone dose was modified according to disease activity. The follow-up lasted 50 weeks and disease activity improved in all cases during Infliximab therapy. Two patients presented arthralgias and sore throat at 20 and 28 weeks, that was rapidly controlled by Infliximab reinfusion every 4 weeks. One patient relapsed at 18 weeks and dropped out at 22 weeks due to an urticarioid rash after the beginning of the fifth infusion. Infliximab may be effective in the treatment of relapse of ASD refractory to conventional therapy and requiring continuous high dose corticosteroid medication. Further studies are needed to evaluate the long-term safety, efficacy and the optimal schedule of infusion.
