title: Low content of hepatic reduced glutathione in patients with Wilson's disease.
abstract: In five of six patients with symptomatic Wilson's disease (WD) with increased hepatic copper content, increased renal copper excretion, and decreased serum concentrations of ceruloplasmin, significantly low levels of hepatic reduced glutathione (GSH) were found. Three of these patients showed increased levels of oxidized glutathione which in part could account for the missing GSH. These changes may result from increased lipid peroxidation due to the rise of intracellular copper concentration. Furthermore, WD patients showed a 50% decrease in the activity of hepatic GSH S-transferases. From these results we conclude that the disturbance in the hepatic glutathione system of patients with symptomatic WD may contribute to the perpetuation of liver damage. These patients, additionally, may be predisposed to an increased sensitivity to drugs interacting with glutathione.
