We measured the activity of carnosinase, a prominent hepatic peptidase, in sera from 69 patients with liver disorders. Mean values (and SDs) for those with liver cirrhosis (17 cases) and hepatoma (seven cases) were 0.51 (0.28) and 0.68 (0.21) mumol/mL per hour, respectively--clearly less than for normal adults: 4.19 (0.95) mumol/mL per hour. Samples from 17 cases of chronic hepatitis also showed moderately decreased activity, 1.41 (0.97) mumol/mL per hour. In contrast, 14 cases of acute hepatitis generally showed values falling within the normal limits: 3.41 (1.97) mumol/mL per hour. Our results for carnosinase correlated with those for cholinesterase (r = 0.70) and with the concentration of albumin in serum (r = 0.59), but not with the activity of either creatine kinase, aspartate aminotransferase, or alanine aminotransferase in serum. Carnosinase values differed more among groups of disorders than did the values for cholinesterase or albumin. Measurement of serum carnosinase activity may be of clinical value in assessing the severity of chronic liver-cell damage, but not in differentiating liver disease from nutritional, muscle, or endocrine disorders.
