Abstract:
:Oxidative and nitrosative stress (O&NS) could play an important role in the pathophysiology of major depression (MDD). The aim of the present work was to evaluate the specific activity of the main peripheral antioxidant defences (superoxide dismutase--SOD and glutathione peroxidase--GPX) and the level of malondialdehyde--MDA (a lipid peroxidation maker), in depressed patients, as compared to an age-matched control group. Also, we were interested to see if there are any differences between first episode vs. recurrent depression groups, in terms of oxidative stress markers. Additionally, we want it to investigate the effects of different antidepressant medication (mirtazapine, venlafaxine, tianeptine and escitalopram) on oxidative status of depressed patients. Our results showed an increased oxidative stress status in the serum of patients with MDD, expressed by a significant decrease of both SOD and GPX specific activities and a significant increase of the lipid peroxidation marker MDA, as compared to the control group. When we analyzed the oxidative stress status in depressed patients based on chronicity we observed significant decrease of SOD and GPX specific activities in recurrent depression group, as compared to the first episode group. Moreover, a very significant increase in MDA concentration was observed in recurrent depression patients, as compared to the first episode group. Our work provides additional evidences of increased oxidative stress in MDD, expressed by altered antioxidant enzyme activity and increased levels of lipid peroxidation. Also, it seems that sub-classifying depression into different subtypes, based on chronicity, can predict differences in the levels of some various oxidative stress markers.
