Diminished plasma levels of vitamin E in patients with severe viral hepatitis.

RRR-alpha-Tocopherol (Vitamin E) was assayed in plasma of 48 patients with viral hepatitis and of 32 healthy controls. In patients with highly elevated serum transaminases (ALT > 100 U/L) vitamin E plasma levels were significantly lower (17.5 +/- 4.8 mumol/L) than in controls (22.7 +/- 4.2 mumol/L, p < 0.01). The vitamin E/lipid ratios (3.12 +/- 0.63 mumol/g) in these patients were 33% lower than those of the controls (4.68 +/- 0.54 mumol/g). The lowered vitamin E levels in patients with acute or chronic viral hepatitis with high activity of disease may be due to free radical-mediated liver injury.
