The relationship between plasma alpha-tocopherol concentration and vitamin E intake in patients with type 2 diabetes mellitus.

Type 2 diabetes mellitus (DM2) predisposes to an increased production of free radicals and a probable reduction in plasma antioxidants, including vitamin E. This cross-sectional study investigated the relationship between plasma alpha-Tocopherol concentration and vitamin E intake in 58 Brazilians with DM2. Plasma alpha-Tocopherol was determined by high-performance liquid chromatography.

The effects of lipoic acid and α-tocopherol supplementation on the lipid profile and insulin sensitivity of patients with type 2 diabetes mellitus: a randomized, double-blind, placebo-controlled trial.

Antioxidants probably play an important role in the etiology of type 2 diabetes (DM2). This study evaluated the effects of supplementation with lipoic acid (LA) and α-tocopherol on the lipid profile and insulin sensitivity of DM2 patients. A randomized, double-blind, placebo-controlled trial involving 102 DM2 patients divided into four groups to receive daily supplementation for 4 months with: 600 mg LA (n = 26); 800 mg α-tocopherol (n = 25); 800 mg α-tocopherol + 600 mg LA (n = 25); placebo (n = 26).

The relationship between arterial elasticity and lipid profile in people with type 1 diabetes mellitus.

A cross-sectional study was carried out to assess small (SAEI) and large (LAEI) arterial elasticity indexes of individuals with T1DM, and its relationship with their lipid profile. There were associations between SAEI and total cholesterol and waist-hip ratio (R(2)=0.29).
