title: Zinc, copper, manganese, and iron in chronic alcoholic liver disease.
abstract: Ethanol consumption and/or liver damage may alter liver content of several trace elements, as iron, zinc, copper, and manganese. This alteration may play a role on ongoing liver fibrogenesis. Based on these facts we have determined liver, serum, and urinary Mn, Cu, Zn, and Fe levels in a group of alcoholic cirrhotics and noncirrhotics with normal renal function, comparing them with those of controls. We have observed low liver zinc and high liver copper--this last in relation with histomorphometrically determined total amount of liver fibrosis--and manganese contents in cirrhotics, together with increased excretion of zinc and iron and decreased excretion of manganese. Zinc, iron, and copper excretion kept a relation with data of severity of cirrhosis, including mortality in the case of urinary copper, independently of the use of diuretics. Thus, liver copper and urinary iron, zinc, and copper excretion seem to be related with data of severity of chronic alcoholic liver disease. Low urinary manganese excretion may play a role on liver manganese overload.
