Summary

Acanthocytes, also termed spur cell, are large erythrocytes covered with spike-like projections which are associated with severe hemolytic anemia. In advanced cirrhosis, acanthocytes may account for 20 to 30% of red blood cells. Up to 70% of cirrhotic patients display anemia and hemoglobin level may fall to below 5 gr/L in spur cell anemia. The true incidence of spur cells in cirrhosis is not known precisely but may avoisinate 45%, typically in patients with advanced cirrhosis.The presence of spur cells usually predicts lower survival rates. Vitamin E is an antioxidant compound that is a component of biological membrane that helps to maintain integrity of lipid bilayers. Vitamin E deficiency leads to erythrocyte hemolysis, which is improved by supplemental vitamin E. This study is an open label single arm phase II study in cirrhotic patients treated for 4 weeks with Tocofersolan (Vedrop), a water-soluble derivative of alpha-tocopherol, and thus an orally bio-available source of vitamin E. The aim of this study is to determine the effect of tocofersolan on red blood cell membranes lipid composition in adult patients with cirrhosis and vitamin E deficiency. Secondary endpoints are the effects of tocofersolan on anemia, hemolysis and acanthocytosis; on lipid peroxidation and oxidative stress; the safety of a 4 week treatment of 700 mg/day.
