A Study on the Level of Oxidative Stress and Inflammatory Markers in Type 2 Diabetes Mellitus Patients with Different Treatment Modalities.

Abstract

The prevalence of type 2 diabetes mellitus is increasing worldwide in all the age group. UKPDS study had shown that good glycaemic control is maintained by the administration of insulin in addition to hypoglycaemic drugs. But, hyperinsulinemia might cause vascular complications in T2DM. Oxidative stress and inflammation are common in diabetes and plays an important role in vascular complications. The study has been designed to estimate and compare the level of oxidative stress and inflammation in type 2 diabetic patients under different treatment modalities. Sixty Type 2 diabetic subjects undergoing treatment were selected from Government Hospital and VMKV Medical College & Hospital at Salem. The subjects were divided into two groups based on treatment modalities, hypoglycaemic drugs subjects as Group-I (30) and hypoglycaemic drugs & Insulin subjects in Group-II (30). BMI was calculated by standard formula and Fasting blood sugar (FBS), postprandial blood sugar (PPBS), glycated haemoglobin (HbA1c), Lipid profile, oxidative stress (MDA) and inflammatory markers were measured by well established methods. SPSS 16.0 version was used for statistical analysis. In our study we have found significantly high levels of BMI, MDA and hsCRP (25.5±2.79, 2.73±1.65, 1.98±0.85) in Group II subjects when compared to Group I subjects (23.4±3.09, 2.23±1.76, 1.168±1.124). Since risk factors like BMI, MDA and hsCRP were high in Diabetes mellitus patients on both oral hypoglycaemic drugs and insulin, they are more susceptible to cardiovascular diseases. Evaluation of these markers at regular interval can reduce the incidence of vascular complications in Type 2 DM patients.
