OXIDATIVE AND ANTIOXIDANT STATUS IN DEPRESSIVE DISORDER PATHOLOGY

摘要

Depressive disorder is a psychiatric disorder often found lately. Oxidative stress is a mechanism that promotes the occurrence of major depressive disorder . Oxidative stress is defined as an imbalance between oxidants and antioxidants whereby high oxidant content is due to decrease the antioxidant cap city of the system. Objective : The aim of this study is to assess the oxidative and antioxidative status in plasma in patients diagnosed with clinical depression , and to assess whether there is a relationship between oxidative stress and severity of depression . Methods : In this study we gather 50 patients with depression according to the Diagnostic and Statistical Manual of Mental Disorders fourth edition and 20 healthy control subjects . Activity levels of plasma malondialdehyde , superoxide dismutase and glutathione peroxidase were measured in this study to assess the oxidative status and antioxidative defense prior to antidepressant medication . Results : Patients with depression had higher total plasma peroxide and lower plasma antioxidants than controls . Depressed oxidative stress index values patients were significantly higher than controls , and there is a significant positive correlation between the scale and the Hamilton depression Rating Oxidative stress index value . Conclusion : Patients with major depression are exposed to oxidative stress , and oxidative stress index may be useful to reflect the severity of the disease .
