Prolyl hydroxylase activity in normal and diseased human liver.
Prolyl hydroxylase activity was determined in liver biopsy samples obtained from 10 patients. The liver prolyl hydroxylase values in patients with active hepatitis distribute into two numerical populations based on the extent of elevation over control. The first of these groups includes those with enzyme levels elevated approximately 2.5-fold over normal. Included in this group are patients with active (but nonagrressive) hepatitis and patients where advanced portal fibrosis is already established. The second group where prolyl hydroxylase is elevated approximately nine-fold is comprised of two patients with advanced clinical symptoms of active alcoholic hepatitis with evidence of aggressive cirrhosis but with only early minimal evidence of existing fibrosis.
