[Serum and tissue concentrations of zinc after oral supplementation in chronic alcoholics with or without cirrhosis].
Seric and hepatic zinc concentrations are decreased in chronic alcoholics, particularly those with cirrhosis. The purpose of this study was: 1) to assess the duration of zinc intake necessary to normalize seric and hepatic zinc concentrations; 2) to demonstrate that this supplementation did not increase zinc concentrations in other tissues (erythrocytes, leukocytes and hair) and did not induce adverse reactions. Twenty alcoholic patients with (group A: n = 13 or without (group B: n = 7) cirrhosis received zinc sulfate 600 mg daily during 10 days, 10 patients with alcoholic cirrhosis during 30 days (group C) and 7 during 60 days (group D) and were compared with a group of 30 normal subjects. Serum zinc concentrations increased to normal values in all groups of patients. Hepatic zinc increased significantly in groups B (p less than 0.05) and D (p less than 0.01). Zinc concentrations in erythrocytes, leukocytes and hair were unchanged. No adverse reactions were observed. We conclude that seric zinc concentrations reached normal values in alcoholics with or without cirrhosis by daily supplementation of 600 mg zinc sulfate during 10 days to 2 months while hepatic zinc concentrations increased but remained under normal values in some patients, particularly those with cirrhosis.
