Abstract

Abstract : Objective: To assess the medication and disease burden of young adults with juvenile idiopathic arthritis (JIA). Methods: Young adults with JIA prospectively followed in the Juvenile Arthritis Methotrexate/Biologics long-term Observation reported on their health status and medication use. All medications taken (disease-modifying antirheumatic drugs (DMARDs)/prescription/over-the-counter drugs, but excluding most local therapies) classified according to the Anatomical Therapeutic Chemical Classification System were included in this analysis. Medication use at last follow-up was evaluated by sex, JIA category and time from symptom onset to the first biological DMARD (bDMARD) start. Results: A total of 1306 young adults (68% female) with JIA and a mean disease duration of 13.6±6 years were included in the study. Patients reported using on average 2.4±2.1 medicines and 1.5±1.7 non-DMARD medicines, respectively, at the last follow-up. Almost a quarter of the patients reported polypharmacy. The higher the number of medications used was, the higher the disease activity, pain and fatigue, and the lower the quality of life of patients. Medication usage differed significantly between sexes and JIA categories, being highest in patients with rheumatoid factor-positive polyarthritis and systemic JIA. The number of medications used was significantly associated with the time from symptom onset to bDMARD start. Patients taking opioids or antidepressants had a particularly high disease burden and had received bDMARDs an average of 2 years later than patients not taking these medications. Conclusion: Medication use in adults with JIA varies depending on sex, JIA category, and the time between symptom onset and initiation of treatment with bDMARD.
