Introduction:
Oxidative stress is now recognized as being the cause and the consequence of cardiovascular diseases.
Objective:
The role that oxidative stress parameters and inflammatory markers may play in diabetes and related cardiovascular disease (CVD) among Tunisian coronary diabetic patients.
Patients And Methods:
We measured the erythrocyte glutathione peroxidase (GPX), the superoxide dismutase (SOD) activities and the plasmatic total antioxidant status (TAS) concentration by colorimetric methods, the hs-CRP by immunonephelometry assays.
Results:
TAS and GPX were significantly decreased among patients compared to the controls (1.14 ± 0.28 mmol/l vs 1.55 ± 0.35 mmol/l; 59.32 ± 10.72 U/gHb vs 149.19 ± 30.95 U/gHb). For the diabetic patients, TAS is correlated positively with hs-CRP (r=0.01, p<10(-3)). At the not diabetic subjects, TAS is correlated negatively with the hsCRP.
Conclusion:
Determination of antioxidative defense markers contributes to understanding the effect of stress oxidative on the development and the prevention of cardiovascular disease.
