    Abstract:
    OBJECTIVES: The histological diagnosis of the different stages of alcoholic liver disease is not systematic. The aim of this study was to assess whether common biological features were useful in identifying the different stages. METHODS: One thousand twenty six alcoholic patients with liver histology and without any associated diseases or infections likely to alter serum liver tests were studied. Diagnostic analyses were performed using stepwise discriminant analysis in the entire population and in asymptomatic patients. RESULTS: a) Serum ASAT activity levels were only normal in 39% of the patients with normal histological liver and in 14% of the patients with steatosis; b) liver failure was already present in patients with fibrosis without cirrhosis; c) betagamma block was the only biochemical parameter which confirmed the diagnosis of cirrhosis without biopsy; d) the diagnostic accuracy of common tests was weak for the diagnosis of alcoholic liver disease without cirrhosis but prothrombin time could be useful in excluding the diagnosis of cirrhosis with and without acute alcoholic hepatitis when liver biopsy is not available. CONCLUSION: Only a prothrombin time of 80% with a negative predictive value of 94% and the presence of beta-gamma [corrected] block with a positive predictive value of 98% were useful for assessing the diagnosis of cirrhosis in all patients with alcoholic liver disease.
