Demographic, nutritional and clinical predictors of inflammation (high-sensitivity C-reactive protein [hsCRP]), endothelial activation (sE-selectin), and endotoxemia (endotoxin) were assessed.
At postoperative day 7, the sepsis-positive group continued to demonstrate an increase in intestinal permeability, endotoxemia and elastase; a significant difference was observed between the two groups (P = 0.02), whereas there was no significant difference in IL-1, IL-6, and CRP levels.
The pattern of change in the postoperative period of intestinal permeability, systemic endotoxemia and elastase concentration is significantly higher in patients in whom sepsis develops, while the concentration of IL-1β, IL-6, and CRP does not permit to distinguish infection from inflammation.
Serum zonulin was analyzed using ELISA, and markers for metabolic endotoxemia (LPS), inflammation (high-sensitive C-reactive protein and glycoprotein acetylation GlyA), glucose metabolism (fasting glucose and insulin), and lipid metabolism were measured.
In contrast, acute cytokine responses during endotoxemia were lower in AA than EA (e.g. median (IQR) peak IL-1RA, 30 (38) vs.43 (45) ng/ml P=0.002) as was the induction of hepatic acute-phase proteins (e.g. median (IQR) peak CRP 12.9 (9) vs.17.4 (12) mg/L P=0.005).
In contrast to circulating tumor necrosis factor-alpha and C-reactive protein, blood and monocyte Lp-PLA₂ messenger ribonucleic acid decreased transiently, and plasma Lp-PLA₂ mass declined modestly during endotoxemia.
