Abstract

Background Reactive oxygen species (ROS) may play a role in some neuropsychiatric disorders. There is some evidence that the activation of immune-inflammatory process, increase of monoamines catabolism, and abnormalities in lipid compounds may cause overproduction of ROS and, in turn, antioxidative enzyme activities (AEAs) and lipid peroxidation (LP), and that these phenomena may be related to pathophysiology of major depression.Methods The aims of this study were (i) to examine the AEAs and LP levels of the major depressed (MD) patients, and to compare these with healthy controls; and (ii) to investigate the effect of subchronic treatment with selective serotonin reuptake inhibitors (SSRIs) on AEAs and LP levels in MD subjects. Thirty MD patients, and 32 healthy controls (HC) participated in this study. AEAs and LP levels were determined by measuring several antioxidative enzymes and malondialdehyde (MDA) levels in plasma and/or in red blood cells.Results Major depressed patients, especially melancholic patients, had higher AEA and LP levels than those of healthy controls. After treatment for 3 months with SSRIs, AEA and LP levels of the patients were significantly decreased to normal levels.Conclusion These findings suggest that (i) major depression, especially with melancholia, is associated with elevated AEAs and LP, and that (ii) subchronic treatment with SSRIs may have a suppressive effect on AEA and LP. CLINICAL IMPLICATION AND LIMITATION: AEAs might be used for monitoring SSRIs effects.

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.
