Abstract

Oxidative stress may contribute to the pathophysiology of bipolar disorder. The aim of this study was to investigate the serum levels or activities of oxidative stress markers in bipolar patients in a manic phase, and evaluate the changes in superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), thiobarbituric acid reactive substances (TBARS), protein carbonyl content (PCC) and 8-hydroxy 2'-deoxyguanosine after treatment (8-OHdG). We consecutively enrolled 23 bipolar inpatients in a manic phase and 40 healthy subjects. Serum oxidative stress markers were measured with assay kits. All patients were evaluated by examining the correlation between oxidative stress markers and Young Mania Rating Scale (YMRS) scores. The serum TBARS levels in bipolar patients in a manic phase were significantly higher than those of healthy subjects (p=0.006), and serum GPx activity was significant lower than that of healthy subjects (p<0.05). The YMRS scores had a significantly positive association with CAT activity and PCC levels (p<0.05) and a negative association with GPx activity (p<0.05). Twenty bipolar patients were followed up, and their oxidative stress markers were measured at the end of treatment. We found significantly d...Continue Reading
