ABSTRACT
AIM:
Deficiency in vitamin E, a natural antioxidant, participates in abnormal erythrocyte membrane lipids, structural alterations and hemolysis in advanced cirrhosis. Poor absorption of fat-soluble vitamins limits full correction of deficiency with standard formulations in cirrhosis with cholestasis. The aim of the present study was to examine safety and effects of tocofersolan, a water-soluble derivative of vitamin E, on erythrocyte membrane lipids and anemia in patients with biopsy-proven advanced cirrhosis, vitamin E deficiency and hemolysis.METHODS:
Twenty patients (age, 53 ± 10 years; Child class B/C, 8/12), with low plasma vitamin E, chronic anemia and hemolysis, received oral tocofersolan 700 mg/day for 4 weeks. Erythrocyte membrane lipid composition (cholesterol [Chol], phospholipids [Phosph]) was determined by enzymatic assays. Total and conjugated bilirubin, hemoglobin and vitamin E were measured.RESULTS:
Abdominal pain occurred in one patient. Five patients received blood transfusions due to severe anemia. After 4 weeks, both Chol and Phosph decreased, but changes were not significant. Both plasma vitamin E (P < 0.05) and hemoglobin (P < 0.05) increased, together with a decrease in total (P < 0.05) and conjugated (P < 0.05) bilirubin.CONCLUSION:
In patients with advanced cirrhosis, low vitamin E plasma levels and chronic anemia with hemolysis, oral tocofersolan was overall well tolerated, but did not affect erythrocyte membrane lipid composition.
