How is PMR-DAS calculated?

PMR-DAS = 0.35×(shoulder pain VAS 0–10) + 0.1×(duration of morning stiffness in minutes) + 0.22×(physician global 0–10) + 0.035×CRP (mg/L). Disease activity: remission ≤7, active >7.

When should prednisolone be tapered in PMR?

Tapering is guided by PMR-DAS achieving remission (≤7) with stable CRP/ESR. Standard protocol: 15–20mg/day initial, reducing by 2.5mg/month to 10mg, then 1mg/month. Flare occurs in 40–50% during tapering.

PMR-DAS Polymyalgia Rheumatica Activity

Calculate the Polymyalgia Rheumatica Disease Activity Score (PMR-DAS) to assess disease activity in polymyalgia rheumatica, combining pain VAS, morning stiffness, physician global, and ESR/CRP.
