Insights
Current childhood arthritis classification needs updating due to ILAR criteria deficiencies. New systems are being developed by international rheumatology groups like PRINTO to improve pediatric arthritis diagnosis.
Area of Science:
- Pediatric Rheumatology
- Rheumatic Diseases Classification
Background:
- The International League of Associations for Rheumatology (ILAR) criteria for childhood arthritis classification have known deficiencies.
- A revised classification system is needed to accurately diagnose and manage pediatric rheumatic conditions.
Purpose of the Study:
- To review the history and criticisms of current childhood arthritis classification systems.
- To highlight ongoing international efforts to develop improved classification criteria for pediatric arthritis.
Main Methods:
- Review of historical classification systems for childhood arthritis.
- Discussion of major criticisms of the existing International League of Associations for Rheumatology (ILAR) criteria.
- Examination of current initiatives, including the Pediatric Rheumatology International Trials Organization (PRINTO) project.
Main Results:
- The current International League of Associations for Rheumatology (ILAR) system for classifying childhood arthritis has significant limitations.
- Ongoing international collaborative efforts are actively working on developing a new, more robust classification system.
- The Pediatric Rheumatology International Trials Organization (PRINTO) is leading a multi-step process to establish new criteria, currently at step 3.
Conclusions:
- Existing childhood arthritis classification requires revision.
- New classification criteria are essential for advancing pediatric rheumatology research and patient care.
- International collaboration is key to developing effective and updated diagnostic standards for childhood arthritis.
Purpose Of Review:
Childhood arthritis is in need of a new system of classification, owing to deficiencies in the International League of Associations for Rheumatology (ILAR) criteria. We briefly review the history of classification of childhood arthritis, discuss the major criticisms of the current system, and highlight current initiatives to address those concerns.
Recent Findings:
Recent studies in both pediatric and adult rheumatology into the biologic basis of disease as well as the clinical patterns of presentation have informed the efforts toward developing a new classification system. Several efforts are currently underway to improve the classification of childhood arthritis, most notably the project of the Pediatric Rheumatology International Trials Organization (PRINTO). This international alliance of pediatric rheumatologists has begun a 4-step process to create new classification criteria for childhood arthritis. They are currently on step 3 of the process.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
