The Activity of Serum 8-Iso-Prostaglandin F2α as Oxidative Stress Marker in Patients with Diabetes Mellitus Type 2 and Associated Dyslipidemic Hyperglycemia

Background: Oxidative stress has been closely linked to the incidence of diabetic complications. Therefore, the aim of this research article was to study hyperglycemia and abnormal lipid profile in diabetic patient type 2 and its correlation with oxidative stress development as measured by 8-iso-PGF2α and 8-OHdG. Methods: Fifty (50) patients confirmed type 2 diabetes mellitus and eighty (80) non-diabetic control individuals were included in this study. All individuals were tested for blood glucose, lipid profile, 8-iso-PGF2α and 8-OHdG HdG. Results: The age of diabetic patients was observed to be ≥40 yrs in 96% and diabetes was frequently detected in female than in male patients (76% vs. 24%, p < 0.0001). Mean serum lipids were elevated in diabetic patients compared with control individuals (p < 0.0001) except in HDL-C, a significant decrease was recorded (p = 0.04). Serum 8-iso-PGF2α and 8-OHdG were elevated significantly in diabetic patients compared with non-diabetic control and a significant correlation was recorded between them (r = 0.6, p < 0.0001). 8-iso-PGF2α was associated with Age (r = 0.394, p < 0.0001), FBG (0.553, p < 0.0001), LDL-C (r = 0.2, p = 0.023), TG (r = 0.176, p = 0.045) and TC (r = 0.2, p = 0.02). Also, 8-OHdG was associated with age (r = 0.558, p < 0.0001), FBG (r = 0.67, p < 0.0001), LDL-C (r = 0.28, p = 0.001), TG (r = 0.358, p < 0.0001) and TC (r = 0.33, p < 0.0001). Age, FBG, HbA1c, LDL-C, TG and TC showed a significant linear regression with 8-iso-PGF2α and 8-OHdG recording its role as significant predictors for the elevation of 8-iso-PGF2α and 8-OHdG. Therefore, hyperglycemia with oxidative stress development may play a role for dyslipidemia and diabetic complications. Conclusion: Diabetic patient’s type 2 has a higher rate of abnormal serum lipids and correlates significantly with lipid peroxidation and oxidized DNA bases as measured by 8-iso-PGF2α and 8-OHdG. Therefore, 8-iso-PGF2α and 8-OHdG could be used as oxidative biomarkers for evaluating diabetic patients with early prediction of its complications and cancer development.
