Plasma concentrations of biomarkers of endothelial dysfunction and low-grade inflammation.
| CRP (mg/L) | SAA (mg/L) | sICAM (ng/mL) | IL-1ß (ng/L) | IL-6 (ng/L) | IL-8 (ng/L) | TNF-α (ng/L) | sVCAM (ng/mL) | E-sel (ng/mL) | ET-1 (ng/L) | |
|---|---|---|---|---|---|---|---|---|---|---|
| Placebo | 1.6 | 1.6 | 211 | 1.5 | 2.3 | 12.5 | 9.8 | 320 | 158 | 1.4 |
| 0.1–12.2 | 0.4–8.9 | 132–311 | 0.2–19.6 | 0.3–19.4 | 0.3–2788 | 4.7–25.5 | 163–598 | 35–480 | 0.8–2.3 | |
| Tea | 0.9 | 1.6 | 201 | 1.7 | 2.5 | 8.9 | 10.8 | 337 | 125 | 1.5 |
| 0.1–16.1 | 0.3–11.4 | 150–253 | 0.2–17.0 | 0.7–7.8 | 0.5–696 | 6.0–18.4 | 180–576 | 55–347 | 1.0–2.1 |
Values are presented as median with 1st and 3rd quartile due to skewed nature of the data (not normal distributed). EDTA-plasma samples were derived from fasted blood samples. Values are not significantly different (p > 0.1) between interventions. CRP: C-reactive protein; SAA: serum amyloid A; sICAM: soluble intercellular adhesion molecule 1; IL-1β: Interleukin-1β; IL-6: interleukin-6; IL-8: interleukin-8; TNF-α: tumor necrosis factor α; sVCAM: soluble vascular adhesion molecule 1; E-sel: E-selectin; ET-1: endothelin-1.
