EULAR developed a disease activity index for primary Sjogren's syndrome called the ESSDAI. This consists of 12 subscores measuring various components of disease activity. The authors are from the European League Against Rheumatism Sjogren's Task Force.
Patient selection: primary Sjogren's syndrome
Exclude: osteoarthritis
Parameters for articular subscore:
(1) arthralgia with morning stiffness > 30 minutes
(2) 28 joint count for synovitis
