Correlation between biochemical tests, parameters of drug elimination and hepatic enzyme induction in chronic liver diseases

The biochemical liver function tests form an integral part of diagnostic practice in hepatology. In this study the parameters suited for the estimation of drug elimination and of the induced state of the liver, thus the excretion of D-glucaric acid, of menthol glucuronide and the parameters of antipyrine and sulphadimidine kinetics were correlated with the results of biochemical laboratory tests in patients with chronic liver disease. The aim was to establish universally valid quantitative correlations between the above results. Multiple relationships were revealed, but generally valid correlations for the group of liver diseases occurred only in special relationships (serum albumin level and antipyrine T1/2; serum bilirubin level and sulphadimidine T1/2). The results have been evaluated from the methodological aspect to work out an appropriate dosage regime in liver diseases.
