[Comparison of six potential serum markers of hepatic fibrosis in alcoholic disease of the liver].

The aim of this study was to compare 6 potential serum markers for hepatic fibrosis in patients with alcoholic liver disease. Ninety-three patients (50 +/- 11 years old, 62 males) with biopsy-proven alcoholic liver disease were included in the study. A liver biopsy and serum assays of type I, type III and type IV collagens, N-terminal peptide of type III procollagen, laminin (by radioimmunoassays) and apolipoprotein A1 (by nephelometry) were performed in all patients. A histological score of hepatic fibrosis was established. Alcoholic hepatitis lesions and perisinusoidal fibrosis were assessed separately. A significant correlation was found between the score of hepatic fibrosis and serum levels of type I collagen (r = 0.44, P < 10(-3)), type III collagen (r = 0.36, P < 10(-2)), N-terminal peptide of type III procollagen (r = 0.50, P < 10(-3)), type IV collagen (r = 0.44, P < 10(-3)), laminin (r = 0.50, P < 10(-3)), and apolipoprotein A1 (r = 0.21, P < 0.05). After adjustment for the presence of lesions of alcoholic hepatitis and perisinusoidal fibrosis (partial correlation), serum levels of type I collagen, type III collagen, N-terminal peptide of type III procollagen, type IV collagen, and laminin remained significantly correlated with the score of hepatic fibrosis; in contrast, correlation with serum apolipoprotein A1 was no longer significant. Serum levels of N-terminal peptide of type III procollagen, type IV collagen and laminin were significantly higher in patients with perisinusoidal fibrosis.(ABSTRACT TRUNCATED AT 250 WORDS)
