Plasma levels of antiinflammatory compounds (which counteract inflamma
tion, cortisol, IL-1 receptor antagonist, IL-1ra; soluble IL-2 recepto
r, sIL-2r; soluble intercellular adhesion molecule-1, sICAM-1; interle
ukin-10, IL-10) were synchronously determined in a consecutive series
of 25 patients with severe bacterial infections. Serum levels of corti
sol, IL-1ra, sIL-2r, sICAM-1 and IL-10 were significantly higher in pa
tients with infection compared with healthy volunteers. Bacterial infe
ction results in the production of inflammatory and proinflammatory cy
tokines from macrophage/monocyte, which are thought to be involved in
the pathogenesis of systemic inflammatory response syndrome (SIRS). We
found that counter-inflammatory compounds can also be released during
infectious insults. These results suggested that the biological activ
ity of inflammatory mediators is inhibited by natural antiinflammatory
compounds, and the body itself might down-regulate excessive inflamma
tory cascades through counteracting the inflammatory responses and res
tore homeostasis.
