Biotinidase is an enzyme synthesized predominantly by the liver. Serum activity of this enzyme has been shown to be low in chronic liver disease. In this study, we endeavored to assess the diagnostic value of serum biotinidase as a marker of hepatic biosynthetic function in acute and chronic liver dysfunction. Twenty-three patients with acute liver disease and 46 with chronic liver disease, as diagnosed by clinical examination, laboratory tests, histopathology and tests for viral markers, were inducted into the study. Forty-six healthy volunteers were selected as controls. Serum biotinidase activity was estimated in all the subjects. Biotinidase activity was found to be significantly lower in the serum of patients with acute (4.59 +/- 1.26 IU/L vs 7.56 +/- 0.82 IU/L in controls; P</= 0.001) and chronic (2.98 +/- 1.18 IU/L vs 7.56 +/- 0.82 IU/L in controls; P</= 0.001) liver disease. Using receiver-operator characteristic curves, serum biotinidase was found to have high values of sensitivity and specificity when applied as a diagnostic test in both acute and chronic liver disease. These results suggest that serum biotinidase may be a sensitive and specific diagnostic marker of hepatic biosynthetic function in both acute and chronic liver disease.
