Anakinra Drug Retention Rate and Predictive Factors of Long-Term Response in Systemic Juvenile Idiopathic Arthritis and Adult Onset Still Disease

Background and objective: Only a few studies have reported long-term efficacy of interleukin (IL)-1 inhibition in systemic juvenile idiopathic arthritis (sJIA) and adult onset Still disease (AOSD). Herein we report on the effectiveness of Anakinra (ANA), expressed in terms of drug retention rate (DRR), and evaluate the predictive factors of drug survival in patients with both sJIA and AOSD. Patients and methods: This is a multicentre study...
