Oxidative stress and its correlation with glycated haemoglobin in patients of type 2 diabetes mellitus

Background: Type 2 diabetes mellitus (T2DM) has a heavy disease burden and is one of the leading causes of death worldwide. Oxidative stress leads to the generation of inflammatory mediators and reactive oxygen species, which results in an inflammatory state, which plays a key role in the pathogenesis of diabetes and its complications. We aimed to correlate the levels of Glycated Haemoglobin with Oxidative Stress. Methods: This study included 200 subjects, 100 were type 2 diabetics and 100 healthy non-diabetic individuals. All the individuals were subjected to analysis of Fasting Plasma Glucose, Glycosylated Haemoglobin, Malondialdehyde, Superoxide Dismutase, Glutathione, Catalase, Uric Acid and Ascorbic Acid. The data thus generated was analyzed Statistically using the student 憈� test. ANOVA for comparison of mean in more than two groups. Pearson抯 coefficient of correlation was used to calculate the correlation between different parameters. p <0.05 was considered statistically significant. Results: The results showed that as the Glycated Hb increased, the levels of FBS, MDA, Uric acid increased and Serum SOD, Glutathione, Catalase, and Ascorbic acid levels decreased this change was statistically significant (p<0.05). A positive significant correlation between HbA1c, and fasting blood Glucose, MDA, Uric Acid. SOD, Catalase, Ascorbic Acid and Glutathione showed a negative correlation with glycosylated Haemoglobin. Conclusions: It is hereby concluded that when glycated Hb increases the natural antioxidants that are SOD, catalase, and glutathione decrease to combat the increased formation of ROS. Serum MDA, increased with increased glycated Hb and shows a positive correlation, indicating increasing lipid peroxidation.
