Vitamin E modifies neither fructosamine nor HbA1c levels in poorly controlled diabetes

Rev Invest Clin. Nov-Dec 1996;48(6):421-4.

Abstract

Objective: To examine the effects of vitamin E on total serum protein glycation (fructosamine), hemoglobin glycation (HbA1c), and serum levels of glucose, total cholesterol, triglycerides, LDL-C, HDL-C, apolipoprotein A1 and apolipoprotein B.

Material and methods: Sixty poorly controlled diabetic patients were randomly assigned to receive either 1200 mg/day of vitamin E or identical placebo capsules during a two month period following a double blind cross-over design with a four week wash-out period between regimens.

Results: Seven patients were excluded from the study because of reasons not related to the medication. In the remaining 53 patients, the levels of serum glucose, fructosamine, HbA1c, total cholesterol, HDL-C, LDL-C, Apo A1 and Apo B did not vary significantly with vitamin E as compared with placebo.

Conclusions: No significant effects of vitamin E on any of the parameters evaluated were observed in poorly controlled diabetic patients.
