Liver disease of the alcoholic.

Significant liver disease including fatty metamorphosis, alcoholic hepatitis, cirrhosis, and hepatoma occur in two thirds of subjects who consume alcoholic beverages in sufficient quantities to interfere with work and social responsibilities; this is of major importance in the rapidly escalating morbidity and mortality from alcoholism. Chronic alcoholics should be routinely evaluated for the presence of altered liver function and structure. Clearance of indocyanine green using dichromatic ear densitometry and computer and analysis provides a simple and sensitive method for mass screening of such patients. Clinical studies of lymphocyte reactivity to purified alcoholic hyaline may be valuable in recognizing alcoholic hepatitis, the precursor of cirrhosis. Ethanol toxicity, malnutrition and constitutional factors contribute to the development of hepatic fibrosis and cirrhosis in alcoholics. Ethanol and/or acetaldehyde and the supernatant from lymphocytes stimulated by alcoholic hyaline cause a significant increase in the incorporation of proline into collagen of the damaged liver. Abstinence and correction of nutrient deficits are the cornerstones of treatment for alcoholic liver disease; a daily meal and dietary supplements should be provided for those with liver injury who continue to imbibe. Alcoholics with progressive liver disease despite supportive therapy may be aided by pharmacologic agents which suppress immunologic response and reduce fibrogenesis.
