Alcoholic liver disease.
Liver injury may develop in some people who consume alcohol. The pathogenesis of liver damage in such subjects remains obscure. Major histopathologic features of alcohol-associated liver injury include steatosis, steatonecrosis, and cirrhosis. The clinical manifestations of alcoholic liver disease are nonspecific and range from asymptomatic hepatomegaly to stigmata of portal hypertension with advanced parenchymal failure. The severity of the clinical presentation and the degree of aminotransferase elevation correlate poorly with the liver histopathology, particularly in patients who continue to drink alcohol. Short-term mortality of such patients is best predicted by a composite of clinical and laboratory parameters that are influenced by alcohol consumption as well as by liver disease. Long-term prognosis is determined by residual damage to vital organs (that is, whether or not cirrhosis has developed) and whether or not the patient continues to drink. Current therapy of alcoholic liver disease includes abstinence and correction of nutritional deficiencies. Other therapies are experimental and are best utilized in the setting of controlled clinical trials.
