DC-ART: decreased inflammatory synovitis.
As part of the proposal for drug development using the SMARD/DC-ART definitions, "decreased inflammatory synovitis" needs to be defined. We review the literature with respect to each of the indirect, clinical measures of decreased inflammatory synovitis and recommend a preliminary, testable definition based on a per patient response. It includes minimum disease activity criteria for patients entering studies and improvement in at least 5 of the following 6 criteria: greater than 20% improvement in joint swelling count; greater than 20% improvement in joint tenderness count; greater than 20% improvement in erythrocyte sedimentation rate; greater than 30% improvement in physician/assessor global assessment; greater than 30% improvement in pain. While this definition is sensible within the confines of our knowledge to date, using these criteria prospectively in several clinical trials will allow better definition of the appropriate pooled index to define decreased inflammatory synovitis.
