The relevance of oxidative stress status in first episode and recurrent depression

Stefanescu, Cristinel, Ciobica, Alin·2012·Journal of Affective Disorders

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.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Higher oxidative stress, lower antioxidants, and more oxidative stress-related DNA/RNA damage are linked to clinical markers of major depressive disorder progression such as greater chronicity, more episodes, and treatment resistance.

    “greater oxidative stress, lower antioxidant, and greater oxidative stress-related DNA/RNA damage have been linked to clinical markers of MDD illness progression, including greater chronicity, more MDEs, and treatment resistance (98,108–113).”
  • Subclassifying depression into different stages based on chronicity can predict significant differences in levels of lipid peroxidation markers such as MDA and in specific activity of main antioxidant enzymes such as SOD and GPX.

    “our group showed that subclassifying depression into different stages, based on chronicity (e.g., first episode versus recurrent depression), can actually predict significant differences in the levels of some lipid peroxidation markers such as MDA and also in the specific activity of the main antioxidant enzymes such as SOD and GPX [19].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
