JADAS27
Pronunciation: JAH-das twenty-seven
Also written as: JADAS27 — Juvenile Arthritis Disease Activity Score with 27 joints
A standardized composite score measuring disease activity in juvenile idiopathic arthritis using 27 joint counts.
Full Definition
The Juvenile Arthritis Disease Activity Score with 27 joints (JADAS27) is a validated composite measure used to assess disease activity in children with juvenile idiopathic arthritis. The score incorporates four components: physician global assessment of disease activity (0-10 scale), parent/patient global assessment of well-being (0-10 scale), count of joints with active arthritis (0-27), and normalized erythrocyte sedimentation rate. JADAS27 scores range from 0 to 57, with higher scores indicating greater disease activity. This tool is widely used in clinical trials and practice to monitor treatment response and guide therapeutic decisions in pediatric rheumatology.
Usage
Usage note: Specify the number '27' to distinguish from other JADAS variants when documenting scores.
In Context
- "The patient's JADAS27 score decreased from 15 to 4 after three months of methotrexate therapy." — Treatment response assessment
- "A JADAS27 score of less than 1 indicates inactive disease in oligoarticular juvenile idiopathic arthritis." — Disease activity interpretation
