Plasma glutamate dehydrogenase: clinical application in patients with alcoholic liver disease

The time course of plasma glutamate dehydrogenase (GDH) elevation was studied in 42 male alcoholics admitted for alcohol detoxification or for the treatment of medical complications of alcoholism and in 2 volunteers consuming 2 g/kg/day of ethanol under metabolic ward conditions. GDH values were usually highest during or immediately after cessation of drinking; thereafter, they fell rapidly toward the normal range. Early GDH values correlated well with liver histology in 37 patients who subsequently underwent diagnostic liver biopsy.
