ESR, CRP, and PCT values in patients with TA according to activity status and concurrent immunological therapies.
| Active Without Therapies | Inactive Without Therapies | Active While Receiving Therapies | Inactive While Receiving Therapies | |
|---|---|---|---|---|
| No. patients | 1 | 3 | 13 | 24 |
| Mean ESR, mm/h1 | 68 | 14 (8; 7–23) | 35 (23; 3–78) | 11 (9; 1–34) |
| Mean CRP, mg/l2 | 24 | 2.0 (1.0; 0.9–2.7) | 12 (13; 0.9–40) | 3.0 (4.4; 0.1–19) |
