Abstract

Background and aims Studies have already pointed out a possible pathophysiological role of oxidative and antioxidative molecules in bipolar disorder. We aimed to evaluate the activity and levels of antioxidant superoxide dismutase (SOD), and oxidant nitric oxide (NO), in bipolar I depressive episode (BD-DE) patients in a prospective design.Method 30 BD-DE patients, diagnosed according to DSM IV, and 30 healthy volunteer controls were included. The serum levels of NO and SOD have been studied when admitted to hospital (1st) and on the 30th days. Clinical outcome was measured by Hamilton Depression Scale (HAM-D). The patients were allowed to have their treatments. One patient was dropped out due to insufficient sampling.Results As in the previous studies, NO 1st day levels were significantly higher in patients and SOD 1st day activity was significantly low (p<0.01). NO levels significantly decreased (p<0.01) and normalized, as SOD activity significantly increased but did not reach to the controls' levels (p<0.01) on the 30th day.Conclusion Despite normalized NO levels, persistent low SOD activity might point out an oxidative imbalance in BD-DE. Chronic low SOD activity may be associated with incapacity of coping with oxidative stress. This research connotes the probable oxidative imbalance in BD-DE and discusses that phenomenon within the continuum of the disease state.

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.
