- Abstract:
- Alcoholic cirrhosis and viral cirrhosis are associated with alterations of immune system function and cytokine production. Our aim was to investigate whether serum concentrations of soluble receptors for interleukin-2 (sIL-2 R) and tumor necrosis factor (55kD-type, sTNFR-55), and serum neopterin can be used as markers to establish differences in etiology and severity in liver cirrhosis and to determine whether they correlate with laboratory and clinical parameters. Thirty three patients with alcoholic and 15 with viral cirrhosis (classified according to the Child-Pugh score of severity of liver disease) and 43 healthy controls were studied. Serum concentrations of sIL2-R, sTNFR-55 and neopterin were significantly raised in patients. No significant differences between alcoholic and viral cirrhosis were found. The concentrations of sTL-2 R and sTNFR-55 were significantly higher in patients with more severe disease. There existed correlations between sIL-2R and sTNFR-55 (rs = 0.50, P < 0.001) and between both soluble receptors and the Child-Pugh score (sTNF-R55: rs = 0.70, p < 0.001; sIL-2R: rs = 0.33, p < 0.05) and serum albumin. The results are likely to reflect that the monocyte-macrophage and T-cell functions are stimulated in patients with liver cirrhosis independently of the etiology of the disease, and that persistent activation of the immune system occurs in cirrhosis even at the end stage of the disease. Chronic immune activation might have deletereous consequences on the evolution of cirrhosis.
