Effect on malondialdehyde, superoxide dismutase and reduced glutathione and its metabolizing enzymes in vitamin D deficient newly diagnosed Type- 2 diabetic patients.

Abstract

Background: India, with 32 million diabetic individuals, currently has the highest incidence of diabetes worldwide. Recently, World Health Organization (WHO) reported that these numbers are predicted to increase to 80 million by the year 2030. Vitamin D regulates glucose metabolism and oxidative stress is a well-established factor of this multi-factorial disease. Aim: Present, study was designed to evaluate certain oxidative stress markers like malondialdehyde, superoxide dismutase, reduced glutathione, glutathione reductase, Glutathione Peroxidase (GPx) along with total antioxidant activity in vitamin D deficient newly diagnosed Type 2 diabetics. Methods: 150 vitamin D deficient newly diagnosed type 2 diabetics’ and equal number of healthy subjects of both genders were recruited. Fasting blood was collected for evaluation of glucose, 25(OH) D and oxidative stress markers. Results: Significant (P<0.01) increase in malondialdehyde by 51.03% while a significant decrease in oxidative stress markers like SOD, GSH, GR, GPx and total antioxidant activity by 27.91 (P<0.05), 26.14% (P<0.05), 32.04% (P<0.01), 25.41% (P<0.05) and 35.85% (P<0.01) respectively was recorded in vitamin D deficient newly diagnosed type 2 diabetics with respect to healthy controls. Conclusions: A fore mentioned observations suggested that vitamin-D deficient newly diagnosed Type-2 diabetics of North-West Indian’s are associated with oxidative stress, a hallmark of various diseases like Diabetes Mellitus, cardiovascular diseases, osteoporosis etc. Therapeutic interventions in combinations of lifestyle and dietary modification might be beneficial to prevent further risk of development of Diabetes Mellitus and cardiovascular diseases like atherosclerosis in North-West Indians.
