This study investigates pediatric onset rheumatic diseases, which are conditions that affect the joints and muscles in children. The study aims to gather information on how these diseases are currently treated and how active they are in patients. This information will be used to understand the diseases better and to potentially improve treatments for future patients.
Participants in the study will undergo assessments to collect data on their treatment plans and disease activity. The study focuses on conditions like Juvenile Idiopathic Arthritis (JIA) and Systemic Lupus Erythematosus (SLE), and it includes various procedures to monitor these conditions over time.
- Who can participate: Children with Juvenile Idiopathic Arthritis (JIA) who had disease onset before age 16, or those with Systemic Lupus Erythematosus (SLE) before age 18, are eligible if they have active arthritis or meet specific clinical criteria related to SLE.
- Study details: Participants will be involved in assessments to gather information about their treatment plans and disease activity. The study does not involve any experimental treatments or medications.
