Anti-CCP antibodies in Brazilian children and adults with juvenile idiopathic arthritis

Area of Science:

• Rheumatology
• Pediatric Rheumatology
• Immunology

Background:

• Juvenile idiopathic arthritis (JIA) often persists into adulthood, necessitating transition of care.
• Continuous inflammatory activity in JIA patients during adult life requires proactive management strategies.
• Identifying patients at risk for prolonged disease is crucial for effective healthcare planning.

Purpose of the Study:

• To determine predictors for juvenile idiopathic arthritis (JIA) patients requiring ongoing care in adult rheumatology clinics.
• To differentiate characteristics of JIA patients managed in pediatric versus adult settings.

Main Methods:

• Comparative analysis of clinical, serological, and demographic data.
• Retrospective study comparing 45 JIA patients from a pediatric clinic with 49 JIA patients from an adult rheumatology clinic.
• Statistical analysis to identify significant differences between the two groups.

Main Results:

• Patients in the adult clinic exhibited a significantly older age at disease onset (p < 0.0001).
• A higher prevalence of positive anti-cyclic citrullinated peptide (CCP) antibodies was observed in the adult JIA cohort (p = 0.05).
• No significant differences were found in JIA subtype, rheumatoid factor (RF) status, uveitis presence, or gender distribution.

Conclusions:

• Older age at disease onset and positive anti-CCP antibodies are potential biomarkers for identifying JIA patients who will require continued care into adulthood.
• These findings can aid in optimizing the transition of care for JIA patients from pediatric to adult rheumatology services.
