Abstract
Serum selenium was evaluated in relation to hepatic structure and function in 46 alcoholics with diagnostic liver biopsy classified into 4 groups by hepatic histology. Their serum selenium concentration varied from 12 to 88 µg/1 and was lower (p < 0.001) in all groups of alcoholics, ie patients with normal liver (53.0 ± 20.7 µg/1, mean ± SD), fatty liver (55.8 ± 21.2 µg/1), alcoholic hepatitis (46.0 ±14.1 µg/1), and cirrhosis (41.1 ± 12.8 µg/1), than in 25 healthy controls (88.7 ± 11.0 µg/l). Serum selenium level was related to the severity of liver disease, and most reduced in subjects with decompensated alcoholic cirrhosis. Their serum selenium level (29.2 ± 13.7 µg/l) was below (p < 0.05) that obtained in alcoholics with normal liver and fatty liver respectively. Both inadequate dietary selenium intake and alcohol-induced changes in hepatic structure and function may have contributed to the decrease of serum selenium in the subjects studied.
