Biochemical markers of inflammation in plasma
| IL-6 (ng/l) Median (range) | CRP (mg/l) Median (range) | |
|---|---|---|
| Vasc pat (n = 59) | 3·6 (0·8–25·5) | 8·5 (0·0–35·4) |
| Smouldering (n = 15) | 7·0 (1·9–25·5) | 16·2 (3·2–35·4) |
| Remission (n = 44) | 2·4 (0·8–7·7) | 6·0 (0·0–29·1) |
| HighProt3 (n = 25) | 3·6 (0·8–25·5) | 9·7 (0·0–33·6) |
| NormProt3 (n = 34) | 3·6 (1·0–16·6) | 7·6 (0·0–35·4) |
| DC (n = 48) | 3.9 (1·3–14·6) | – |
| HBD (n = 30) | 1·0 (0·3–2·4) | 1·6 (0·0–8·0) |
Vasc pat = all vasculitis patients. Smouldering: patients with smouldering disease activity. Remission = patients in remission. HighProt3 = patients with proteinase 3 levels>2 s.d. above the HBD mean value. NormProt 3 = patients with proteinase 3 levels ± 2 s.d. of the HBD mean value. DC = disease controls. HBD = healthy blood donors.
