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: fever of infectious origin
Parameters for constitutional subscore:
(1) fever in °C and night sweats
(2) involuntary weight loss in percent
involuntary weight loss in percent =
= (involuntary weight loss) / (baseline weight) * 100%
