Abstract:
:The metabolism of antipyrine to each of its three major metabolites 4-hydroxy-, 3-methylhydroxy- and norantipyrine has previously been demonstrated to be differentially affected in alcoholic cirrhosis. This study compared the metabolism of antipyrine to its metabolites in 30 patients with alcoholic cirrhosis to 15 patients with non-alcoholic cirrhosis and 20 healthy controls. Both groups of cirrhotic patients were comparable with respect to their disease stage, as assessed by the Child-Pugh classification. Compared to controls, patients with alcoholic and non-alcoholic cirrhosis showed a comparable significant reduction in antipyrine clearance and increase in antipyrine half-life. The reduction in antipyrine clearance was due to a reduction in the formation rate of all three antipyrine metabolites in both alcoholic and non-alcoholic cirrhotics. In both groups, the formation rate of norantipyrine was reduced to a greater extent than of 3-methylhydroxy- and 4-hydroxyantipyrine. No significant differences in the parameters of antipyrine elimination, however, were observed between patients with alcoholic and non-alcoholic cirrhosis. Parameters of antipyrine elimination correlated significantly to the Child-Pugh score and single laboratory parameters, however, the correlation coefficients were generally low (< 0.56). The present results suggest that the P450 enzymes involved in antipyrine metabolism are differentially affected in cirrhosis, but there appear to be no differences in the activity of the enzymes between alcoholic and non-alcoholic cirrhosis. Antipyrine metabolism, therefore, depends on the severity rather than the etiology of liver disease and may serve as a measure of hepatic function irrespective of the cause of liver disease.
