[Management of asymptomatic elevated serum aminotransferase levels, particularly in nonalcoholic steatohepatitis].

At routine determination of serum activities of transaminases (aspartate aminotransferase (ASAT) and alanine aminotransferase (ALAT) increased levels are frequently found. An algorithm may be used in the analysis of elevated transaminase levels: after elimination of the most frequent causes of hepatitis (alcoholic hepatitis, chronic hepatitis B and C) and some rare conditions (autoimmune hepatitis, alpha 1-antitrypsin deficiency, haemochromatosis and Wilson's disease), the diagnosis will often be nonalcoholic steatohepatitis. Although nonalcoholic steatohepatitis is considered a stable disease, recent literature shows a progression to cirrhosis in 8-17%. So far, no effective therapeutic strategies are available for nonalcoholic steatohepatitis.
