AIMS AND OBJECTIVES: Diabetes mellitus (DM) is often termed as a disease of premature aging. Several studies have indicated lopsided redox balance due to pro oxidant environment as one of the important etiological factors. Some recent researches also indicate a causal relationship with oxidative stress (OS). So far, no study has been undertaken on this aspect in Nepali populations. We, therefore, aimed this maiden study in Nepali population to examine redox balance by measuring OS and antioxidant status along with lipid profile in 37 patients of DM type- 2 and 30 matched normal subjects. METHODOLOGY: Thirty seven patients of DM type-2 without any complications (mean age= 57.6+/- 10.6 years) and 30 normal subjects (mean age= 55.8 +/- 14.8 years) were included in this study. Body Mass Index (BMI) and Waist/Hip (W/H) ratio were measured. Fasting blood sample was collected for the analysis of total antioxidant activity (TAA), plasma and urinary thiobarbituric acid reactive substances (TBARS) and lipid profile by standard procedures in both the groups. The statistical analysis was done with SPSS 10 version. RESULTS: Total cholesterol, triglyceride, VLDL-cholesterol, LDL-cholesterol, plasma and urinary TBARS were significantly raised whereas, plasma TAA was significantly reduced in DM type-2 patients as compared to controls. The comparison of old and fresh cases revealed that though TAA was lower and PTBARS and UTBARS were higher in patients but did not attain the level of significance. W/H ratio is significantly higher in patients compared to normal subjects. But, no significant correlation of BMI and W/H with lipid profile is observed in both control and patients. CONCLUSION: Oxidative stress is raised in type 2 DM patients. This along with deranged lipid profile and decreased antioxidant status could be the risk factors in the development of complications associated with DM.
