Abstract
Aim Diabetes is associated with abnormalities in lipid profile and increased oxidative stress. Statins are preferred agents in diabetic patients due to their antioxidant and LDL-C lowering effects. This study is designed to compare the effects of atorvastatin and rosuvastatin on low density lipoprotein cholesterol (LDL-C), lipid hydroperoxide (LOOH), total oxidant status (TOS) and total antioxidant capacity (TAC) in diabetic patients with hyperlipidemia. Materials and methods Sixty two patients who have type 2 diabetes mellitus with serum LDL levels more than 100 mg/dL were randomly assigned to receive atorvastatin 20 mg ( n = 31) or rosuvastatin 10 mg ( n = 31). Blood tests were performed at the beginning of the study and after three months. Results There were no statistically significant differences in the pre- and after treatment levels of the LDL-C between groups. TAC values were increased in both groups and statistically significant in the former group ( p = 0.007). There was no diferrence between the change percentages ((after treatment TAC − pretreatment TAC) / pretreatment level) of TAC between two treatment groups. The effects of two drugs on the other oxidative parameters were not significantly different. Conclusion Both atorvastatin and rosuvastatin may be helpful in reducing increased oxidative stress in diabetic patients with hyperlipidemia.
