Radiological Peripheral Involvement in a Cohort of Patients with Polyarticular Juvenile Idiopathic Arthritis at Adulthood

Juvenile idiopathic arthritis (JIA) is a heterogeneous group of 7 diseases classified by the International League of Associations for Rheumatology (ILAR)1. Two forms with polyarticular onset were identified: rheumatoid factor (RF)-positive and RF-negative polyarticular JIA (pJIA)1.

RMDs are highly prevalent and significantly affect activity limitations and participation restrictions. More effort is needed to improve care and research in this field.
