Primary outcome: disease activity
Juvenile Arthritis, inflammatory joints
JUVENILE ARTHRITIS, DISEASE, DISEASE
Disease activity will be assessed by the change in Juvenile Arthritis Disease Activity Score (JADAS-27) between the initial assessment (V0) and V1 (week 14).The JADAS-27 score consists of four parts, three of which are directly related to the disease, and the fourth to patient well-being, as follows:The number of inflammatory joints among 27 identified,A physician assessment of clinical disease activity on a 10-point visual analogue scale (VAS),An assessment of patient’s well-being by a 10-points VAS, scored by the patient or a parent,The normalized erythrocyte sedimentation rate (0 to 10).JADAS-27 scores range from 0 to 57. The higher the score, the more active the disease. It is expected that the JADAS-27 score will be reduced by 2.7 points between the initial assessment (V0) and 14 weeks (V1 - post APA program). This minimal clinically important difference (MCID) corresponds to the decrease needed to go from low clinical impairment (
