Oxidative stress and generalized inflammatory state are features of bipolar disorders (BD). The objective of this study was to compare the levels of products of inflammatory reaction and oxidative stress markers in patients with bipolar disorders and attention deficit/hyperactivity disorder (ADHD) and to determine the relationship between oxidative stress and inflammation in bipolar disorders. ADHD+BD (n = 30) and BD (n = 30) and healthy controls (n = 30) were enrolled. A clinical evaluation and measurements of malondialdehyde (MDA), high sensitive C reactive protein (hsCRP) and myeloperoxidase (MPO) were performed. Patients with BD+ADHD comorbidity had significantly higher mean MPO levels than BD. Patients with BD had significantly higher mean hsCRP levels than healthy controls. However, there was no significant difference in mean serum hsCRP levels between patients with BD+ADHD and healthy controls. Patients with BD and BD+ADHD had significantly higher mean MDA levels than healthy controls. Our data showed that there is an increased susceptibility to oxidative stress which is strongly related to the serum levels of MDA produced in the serum. hsCRP levels were higher in BD patients than in BD+ADHD and this is suggestive of a higher degree of inflammatory activity in BD patients. ADHD+BD comorbidity seems to augment oxidative stress which is expressed as increased MPO level in the present study. Further large scale studies are needed to extend our results.
