How Is Rheumatoid Arthritis Remission Defined?
The Updated Rheumatoid Arthritis Remission Definition
The American College of Rheumatology and European League Against Rheumatism analyzed clinical trial data and surveyed committee members before deciding on two definitions for rheumatoid arthritis remission which primarily apply to use in clinical trials.
To be considered in remission, a clinical trial participant would need to have:
- Tender joint count – less than or equal to 1
- Swollen joint count – less than or equal to 1
- C-reactive protein – less than or equal to 1 mg/dl
- Patient global assessment score – less than or equal to 1 on a 0 to 10 scale
CRP or C-reactive protein is a specific protein produced in the liver which is elevated in the presence of acute inflammation or infection.
