Assessment of Disease

≤ 4 Remission > 4 and ≤ 14 Low > 14 and ≤ 28 Moderate > 28 High Composite indices for disease activity assessment Disease Activity index for PSoriatic Arthritis (DAPSA) • a validated and easy to use measure for clinical and trial use in PsA • based on the summation of fve variables: SJ66+TJ68+PtGA (cm)+pain VAS (cm)+CRP (mg/dL) • DAPSA evaluates only peripheral joints and does not refect axial involvement. DAPSA (Disease Activity in Psoriatic Arthritis) Score Tender Joints Swollen Joints 1. Tender Joints Count (0-68), TJ: 2. Swollen Joints Count (0-66), SJ: 3. CRP (mg/dl): 4. Patient's assessment of disease activity and pain How active was your rheumatic disease on average during the last week? How would you describe the overall level of joint pain during the last week? DAPSA = TJ + SJ + CRP + ACTIVITY + PAIN = Disease Activity: 0-4 Remission, 5-14 low, 15-28 moderate, >28 high Disease Activity Ref: Eberl G. Rheumatology (Oxford) 2000;39:148–55. Schoels MM. et al.
