Abstract

Background: Type 2 diabetes mellitus is associated with premature atherosclerosis and arterial stiffening by an accumulation of advanced glycation end-products in vessel wall (1). Green tea polyphenols are considered a cardioprotective substance and may be used as an adjuvant for diabetes treatment, because its ability to stimulates the soluble RAGE secretion (2). There is no clinical evidence of the effect of green tea extract administration on metabolic parameters, arterial stiffness and the soluble RAGE expression.

Material and Methods: A double-blind, placebo-controlled, randomized clinical trial in normotensive patients with type 2 diabetes mellitus was conducted to identify the effect of green tea extract on arterial stiffness, metabolic and anthropometric parameters and on soluble RAGE (sRAGE) with the S100A1 ligand.

Results: We included 20 subjects, there was no difference between groups at baseline. There was a decrease in the green tea extract group on aortic augmentation index (21.12±8.9 to 18.07±9.7, p = 0.045), total cholesterol (203.9±37.6 to 176.9±25.9 mg/dl, p = 0.019) triglycerides (202.6±146.9 to 123.2±64.8 mg/dl, p = 0.023) and an increase in sRAGE (1358.5±390.0 to 1281.1±369.7 p = 0.052).

Conclusions: Green tea extract reduces lipid levels, percentage of aortic augmentation index and increases soluble RAGE concentrations in normotensive patients with Type 2 Diabetes.
