    Abstract:
    BACKGROUND/AIMS: Prolonged acute-phase response and increase of cytokines have been associated with higher mortality and surgical complications. This study investigated the status of cytokines and acute-phase response markers in patients with obstructive jaundice. METHODOLOGY: Forty-one patients were investigated. Endotoxin, tumor necrosis factor-alpha, interleukin-6, nitric oxide, C-reactive protein, liver enzymes, albumin and percentage of weight loss were determined at admission. RESULTS: Endotoxin, interleukin-6 and C-reactive protein were significantly elevated in both benign and malignant obstructive jaundice. Increased plasma levels of tumor necrosis factor-alpha were only detected in malignant tumors (68 vs. 24 pg/mL; P < 0.001). Patients with positive acute-phase response (C-reactive protein > mean + 2 SD of controls) had greater weight loss (P = 0.02), endotoxin (P = 0.03) and interleukin-6 plasma levels (P = 0.05) than those with no inflammatory response. Prolonged biliary obstruction (> 10 days) was associated with higher weight loss (P = 0.04), tumor necrosis factor-alpha (P = 0.003) and interleukin-6 (P = 0.05) plasma levels. CONCLUSIONS: A prolonged high-grade biliary tract obstruction prompted an increase in endotoxin levels, associated with a positive acute-phase response and cytokine elevation.
