Diagnostic utility of laboratory tests in alcoholic liver disease.
Alcoholic liver disease is an important health problem in the US. A public health approach is proposed, using laboratory tests to identify patients with early fibrosis of the liver. A variety of serological markers of liver fibrosis based on collagen-related products (e.g., amino-terminal propeptides of type III procollagen) have been investigated. Further studies are needed to determine the optimal combination of tests for discriminating between steatosis and early fibrosis. Laboratory tests are also useful in excluding nonalcoholic liver diseases such as viral hepatitis, hemochromatosis, and Wilson disease. The monitoring of sobriety in patients with alcoholic liver disease by currently available tests is far from ideal. A new marker of excessive alcohol consumption, carbohydrate-deficient transferrin, is not usually affected by liver disease and thus shows promise as a marker of relapse in alcoholic patients. The development of reliable screening markers of fibrosis and sobriety could potentially reduce the health costs and suffering associated with the complications of alcoholic cirrhosis.
