  • Title: Clinical and diagnostic significance of aspartate aminotransferase isoenzymes in sera of patients with liver diseases.
    Author: Panteghini M, Malchiodi A, Calarco M, Bonora R.
    Journal: J Clin Chem Clin Biochem; 1984 Feb; 22(2):153-8. PubMed ID: 6716055.
    Abstract:
    Serum aspartate aminotransferase isoenzymes were measured in 123 hospital patients with various liver diseases, using a new and simple immunochemical method. Our findings show the usefulness of this determination in estimating the severity of hepatic damage, especially if accompanied by the measurement of other mitochondrial enzymes. During hepatic damage, the cytoplasmic isoenzyme is found in greater quantities than the mitochondrial isoenzyme, but the level of the latter increases to a greater extent in acute liver diseases. Moreover, the values of mitochondrial aspartate aminotransferase activity and the ratio of mitochondrial to total aspartate aminotransferase in alcoholic hepatitis are higher than expected if so-called hepatic enzymes commonly measured in serum are considered. These results indicate that there is significant mitochondrial damage in alcoholic hepatitis.
