ALTERATIONS IN PLASMA ANTIOXIDANT ENZYME LEVELS AND SERUM LIPID PROFILE PARAMETERS IN RELATION TO LIPID PEROXIDATION IN INDIVIDUALS WITH MATERNALLY INHERITED TYPE 2 DIABETES MELLITUS
AbstractAim: The present study aimed to evaluate the antioxidant potential and lipid profile parameters, in relation to lipid peroxidation in patients with maternally inherited type 2 diabetes mellitus and in healthy normal individuals. Methods: All standard methods were used to estimate enzymatic antioxidants [Catalase, Copper containing Superoxide Dismutase (CuSOD), Manganese containing Superoxide Dismutase (MnSOD) and Glutathione Peroxidase (GPX)], non enzymatic antioxidant [Reduced Glutathione (GSH)], lipid peroxidation [Malondialdehyde (MDA)]; and lipid profile parameters [High Density Lipoprotein (HDL), Low Density Lipoprotein (LDL), Triglyceride (TG) and Cholesterol]. Correlations between MDA and all parameters were sought using Spearman’s rank correlation coefficient. Results: Significantly lower mean activities of catalase, CuSOD, MnSOD and GSH and significantly higher mean activity of GPX and higher mean concentration of MDA were reported in plasma samples from patients with type 2 diabetes mellitus as compared to healthy individuals. A significantly lower mean level of HDL and significantly higher mean levels of LDL, TG and Cholesterol were noted in patients with type 2 diabetes mellitus than healthy control individuals. Further, weak to moderate correlations were observed between MDA and CuSOD, MnSOD and GPX. No significant correlation was observed between MDA with GSH and with lipid profiles. Conclusion: In conclusion, lipid peroxidation may be a useful marker for early diagnosis and prognosis of secondary complications in patients with maternally inherited type 2 diabetes mellitus
