摘要：

Serum levels of interleukin-1 (IL-1 beta), interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-alpha), interferon gamma (IFN-gamma), and C-reactive protein (CRP) were investigated in patients with chronic liver diseases (CLD) and correlated with the type of underlying disease and various clinical and laboratory parameters. Two hundred sixty-four patients suffering from various CLD were studied; 136 cases presented with liver cirrhosis, and 128 patients were in the noncirrhotic stage of their underlying liver diseases. Serum levels of IL-1 beta, IL-6, TNF-alpha, IFN-gamma, and CRP were elevated in patients with CLD. Endogenous cytokine patterns in CLD were stage dependent and only marginally affected by the type of underlying disease. The cirrhotic group of CLD patients showed higher serum levels in IL-1 beta, IL-6, TNF-alpha, and CRP than did noncirrhotic cases, and these differences reached the level of statistical significance. IL-1 beta and TNF-alpha values were closely correlated but did not correlate with IL-6 levels. Elevated concentrations of cytokines represent a characteristic feature of CLD regardless of underlying disease. This and the apparent stage-dependency suggest that enhanced endogenous cytokine levels represent a consequence of liver dysfunction rather than of inflammatory disease.
