title: Drug metabolism in drug-induced liver diseases: pathogenetic role of active metabolites.
abstract: Three cases with drug-induced liver diseases (hepatitis caused by hydralasine, steatosis caused by methimazole, choletasis caused by birth control pill) were investigated with respect to their drug metabolising ability. Clinical diagnoses were based on the exclusion of other pathogenetic factors, on histological findings of liver biopsy specimens and on the clinical chemical tests. Investigation of biotransforming ability was carried out using test materials (menthol loading, antipyrine, sulfadimidine, caffeine, indocyanine green kinetics) and measurement of D-glucaric acid excretion. In all cases the results show a defective capacity in some respect of drug metabolism. Possible pathogenetic role of reactive metabolites is discussed in the pathomechanism of genesis of drug-induced liver diseases.
