Abstract:
Objective: To explore the clinical significance of 7-joint ultrasound score (US7) method in evaluating the progression of RA. Methods Totally 198 RA patients were divided into 3 groups according to disease activity score of 28 joints (DAS28), i.e. light active period group (n=55), medium active period group (n=83) and heavy active period group (n=60). Gray-scale ultrasound (GSUS) and power Doppler ultrasound (PDUS) were performed on the severe lateral wrist joints, the second/third metacarpophalangeal joints, proximal interphalangeal joints and the second/fifth metatarsophalangeal joints. US7 scoring was performed. The differences among 3 groups were compared, and their correlation with the severity of the disease were analyzed. Logistic regression analysis was performed to find the predictive factor of RA. Results: With the severity of disease, DAS28, GSUS synovitis, PDUS synovitis, GSUS tendon tenosynovitis, PDUS tendon tenosynovitis, US7 total score showed significant increase (all P<0.001). There were positive correlation of GSUS synovitis, PDUS synovitis, GSUS tendon tenosynovitis, PDUS tendon tendonitis, US7 total score to the severity of RA (all P<0.001). PDUS synovitis in US7 scoring system was an independent predictor of light-medium activity. PDUS synovitis and GSUS tendon tenosynovitis were independent predictors of medium-heavy activity (all P<0.001). Conclusion: There is correlation between the progression of US7 and RA. PDUS synovitis is an efficient indicator for identifying the severity of RA.
