Plasma high-density lipoproteins and hepatic microsomal enzyme induction. Relation to histological changes in the liver

European Journal of Clinical Pharmacology

Abstract

The relationship between high-density lipoproteins (HDL) in plasma and hepatic structure and microsomal function has been investigated in 54 patients undergoing diagnostic liver biopsy. Plasma HDL cholesterol and major apoproteins were correlated with hepatic histology and microsomal enzyme activity assessed directly as liver cytochrome P-450 concentration and indirectly by plasma antipyrine clearance rate. HDL cholesterol, the concentrations of apoproteins A-I and A-II, the HDL cholesterol/total cholesterol ratio and cytochrome P-450 were low in subjects with moderate or severe hepatic fatty infiltration or cirrhosis when compared with the values for subjects with a normal live. HDL cholesterol and apoprotein A-I and the HDL cholesterol/total cholesterol ratio were directly proportional to the amount of non-fatty parenchyma in the livers. Subjects with a normal liver undergoing treatment with enzyme-inducing drugs, such as phenytoin, phenobarbital and primidone, had higher HDL cholesterol, apoproteins A-I and A-II, HDL cholesterol/total cholesterol ratio, cytochrome P-450 and antipyrine clearance rate than subjects not receiving such therapy. Treatment with inducers appeared to have compensated for the effect of liver disease ...Continue Reading
