Beta-carotene, glycemic control and dyslipidemia in type 2 diabetes mellitus

Abstract EN

Background : Diabetes mellitus is a stressful condition in which the increased production of free radicals impairs the generation of naturally occurring antioxidants like vitamins and carotenoids .

Aim :The present study deals with the changes in serum ß-carotene in type 2 diabetes mellitus, as modulated by glycemic control and oxidative stress .

Subjects & methods : Multiple biochemical parameters were obtained from plasma of 57 patients with type 2 diabetes mellitus ( 25 males and 32 females ) , on oral hypoglycemic with a disease duration of 1- 15 years and 37 healthy normal subject s of matching age and sex to serve as controls .

The biochemical parameters measured in the present study included the glycated Hb (HbA1c ), serum lipids ( total cholesterol TC, triglycerides TG , high and low density lipoprotein cholesterols, HDL-C & LDL-C ), lipid peroxides and serum ß-carotene.

results revealed a marked reduction of ß- carotene in the diabetics in a pattern proportional to that of the glycemic control ,dyslipidemia and oxidative stress .
