  • Title: [1-14C]Ethanol breath test in alcoholic liver disease.

    Abstract:
    The activity of ethanol metabolising enzymes was assessed in 51 patients with alcoholic and non-alcoholic liver disease using tracer doses of [1-14C]ethanol and measuring 14CO2 excretion in the breath. Alcoholic patients with only fatty infiltration of the liver showed significantly increased activity compared with controls. Comparing alcoholic patients with cirrhosis and a serum albumin greater than 28 g/l, activity in those with a recent history of continued heavy drinking was significantly greater than in patients who had abstained from alcohol. In addition, both groups of alcoholic cirrhosis showed significantly more activity than patients with non-alcoholic cirrhosis. The activities of patients with acute alcoholic or viral hepatitis were normal when their prothrombin times were less than 7 sec prolonged, but were reduced when prolongation exceeded 7 sec. These results demonstrate that in chronic alcoholic liver disease, even with cirrhosis, alcohol can still increase the activity of ethanol oxidising enzymes provided hepatic function remains adequate. However, this response is lost in acute liver damage and in chronic alcoholic disease with severe hepatic dysfunction.
