BackgroundOxidative stress triggered by hyperglycemia in diabetic patients leads to macrovascular and microvascular complications, resulting in deterioration in the quality of life.AimsThis study aimed to compare the oxidative stress status and quality of life in participants with type 2 diabetes mellitus according to treatment modality.Patients And MethodsNinety type 2 diabetes mellitus participants aged between 40 and 60 years were included in the study. Forty-five participants were receiving oral antidiabetic drugs and 45 participants were receiving insulin therapy. Total antioxidant status, total oxidant status, and paraoxonase-1 were measured and oxidative stress indices were calculated. The SF-36 quality of life questionnaire was applied to the participants.ResultsThe total oxidant status and oxidative stress indices values were higher in the insulin-treated group than in the group treated with oral antidiabetic drugs. Paraoxonase-1 activities of the oral antidiabetic drugs-treated group were statistically significantly higher than the insulin-treated group. In the oral antidiabetic drugs-treated group, the physical function, social function, and pain subscale scores were higher than that of the insulin-treated group. In all participants, a negative correlation between total antioxidant status and fasting blood glucose and hemoglobin A1c, a positive correlation between total oxidant status and hemoglobin A1c and triglyceride, and a positive correlation was found between oxidative stress indices and fasting blood glucose and hemoglobin A1c.ConclusionsIt was found that oxidative stress parameters were higher and quality of life was worse in the insulin-treated participants than participants treated with oral antidiabetic drugs. These results may be closely related to more severe chronic complications in insulin-dependent diabetes.
