Effect of Type-2 Diabetes Mellitus in Retinopathy Patients on MDA, SOD Activity and its Correlation with HbA1c
Abstract Diabetic retinopathy (DR) is a metabolic disorder of the retina and one of the common problems of Type-2 diabetes mellitus (T-2DM) causing visual loss even at teen ages. In this research article, oxidative stress was the main cause due to reactive oxygen species (ROS) generation at hyperglycemic state and become as the focus point of this study to describe (DR) complication onset. The present study was conducted to compare three groups: T-2DM with complication, T-2DM without complication and control group. For this purpose, number of the individuals participating in this study were n=110 as subject along with T-2DM patients with complication n=50, T-2DM patients without complication n=50 and rest n=10 are taken as control/ normoglycemic individuals. T-2DM patients with/without complication have TAG level is lower than normoglycemic/ control. An observed value of (HbA1c%) glycosylated or glycated hemoglobin type A1c concentration of T2DM with complication group was highest (9.63%) amongst the examined groups. T-2DM with complication has lowest SOD activity (660.96 U/gHb) but the malondialdehyde (MDA) level was found to be higher (5.96 µmol/L) amongst studied groups. Lowest plasma TAG, and higher plasma MDA level indicate the presence of oxidative stress in T2D with/without complications. SOD activity was decreased due to the protein glycation and the surplus level of lipid detoxification especially found in T-2DM cases. Good glycemic control counteracts the response of Lipid peroxidation usually occurs in hyperglycemic state.
