Abstract
Objective of present study is to evaluate the possible role of clopidogrel in improving glycemic indices and oxidative stress in patients with type 2 diabetes. This study was performed on 42 uncontrolled type 2 diabetic patients at the specialized center for Endocrinology and Diabetes, Al-Rasafa Directorate of Health, Baghdad. All of the patients were treated with (glibenclamide 5 mg at morning) and randomized into two groups: the first group includes 22 patients treated with clopidogrel tablets (75 mg/day) for 2 months; the second group includes 20 patients treated with a placebo formula (sodium bicarbonate 200 mg/day) for the same period. Treatment with clopidogrel produced significant improvement (P < 0.05) in fasting serum glucose (FSG), fasting serum insulin level, quantitative insulin sensitivity check index (QUICKI); and oxidative stress markers: serum malondialdehyde (MDA) and serum reduced glutathione (GSH) compared to their baseline levels. There was significant elevation (P < 0.05) in both FSG and fasting serum insulin and the MDA level with significant reduction (P < 0.05) in QUICKI of placebo group compared to their baseline levels. However, clopidogrel produced significant elevation (P < 0.05) in AST and ALT levels but placebo formula caused no significant alteration (P > 0.05) in the serum levels of these two enzymes. In conclusion the treatment with clopidogrel improved glycemic indices and reduced oxidative stress in patients with type 2 diabetes.
