Overview
Juvenile idiopathic arthritis (JIA) encompasses a group of chronic inflammatory arthritis syndromes in children under 16 years, with oligoarthritis affecting fewer than five joints initially 1.Diagnosis
Clinical presentation with arthritis in fewer than five joints 1.
Elevated inflammatory markers (erythrocyte sedimentation rate, C-reactive protein) 1.
Radiological evidence of joint inflammation may be minimal in early stages 1.
Exclusion of other rheumatologic conditions through comprehensive evaluation 1.Management
First-line treatments: Nonsteroidal anti-inflammatory drugs (NSAIDs) for pain and inflammation 1.
Disease-modifying antirheumatic drugs (DMARDs): Methotrexate is often initiated early for persistent disease 1.
Biologics: Tumor necrosis factor (TNF) inhibitors such as etanercept or adalimumab for refractory cases 1.
Physical therapy: Essential for maintaining joint function and mobility 1.
Regular monitoring: Assess disease activity, growth, and development 1.Special Populations
Pediatrics: Focus on minimizing systemic effects and preserving growth 1.
Comorbidities: Management requires tailored approaches considering additional health issues 1.Key Recommendations
Initiate NSAIDs early for pain and inflammation management in oligoarthritis (Evidence: Moderate 1).
Consider early introduction of methotrexate for persistent oligoarthritis to prevent joint damage (Evidence: Moderate 1).
Evaluate and consider biologic agents like TNF inhibitors for patients with refractory oligoarthritis (Evidence: Moderate 1).References
