Clinical predictors of relapse and severe disease phenotype in children with non-systemic juvenile idiopathic arthritis

Key Points

• The study aims to identify clinical predictors of relapse and severe disease phenotype in children with non-systemic juvenile idiopathic arthritis.
• Analysis of clinical data from children diagnosed with non-systemic juvenile idiopathic arthritis
• Assessment of disease duration, age, and specific joint involvement
• Identification of treatment requirements, including bDMARD usage
• Younger age and involvement of ankles and TMJ correlate with severe disease course.
• Longer disease duration is associated with increased frequency of relapses.
• Not all relapses indicate the presence of severe disease phenotype.
