Valentini et al proposed a revised score for expressing activity of systemic sclerosis. The authors are from the European Scleroderma Trials and Research Group (EUSTAE).
Patient selection: systemic sclerosis
Parameters:
(1) skin changes
(2) digital ulcers
(3) modified Rodnan skin score
(4) tendon friction rubs
(5) serum CRP in mg/dL
(6) DLco as percent of predicted

total score =
= SUM(points for all 6 parameters)
Interpretation:
• minimum score: 0
• maximum score: 10
• The higher the score the more active the scleroderma.
Performance:
• The area under the ROC curve is 0.90.
