title: Determination of serum antioxidant vitamins, glutathione and MDA levels in panic disorder patients.
abstract: There are sufficient experimental evidences to establish the relationship between the elevated level of malondealdehyde (MDA)-the lipid peroxidation product and depleted level of antioxidants (Vitamin A, E, C and glutathione) in several psychiatric disorders. But previously no study was carried out to determine these components in panic disorder (PD) patients of Bangladesh. This study was conducted to assess the serum concentration of antioxidant vitamins, MDA and glutathione in 54 panic disorder patients and 52 healthy volunteers. Patients were recruited from Bangabandhu Sheikh Mujib Medical University, Bangladesh by random sampling. Serum level of MDA, glutathione and vitamin C were determined by UV spectrophotometric method whereas Vitamins A and E were detected by RP-HPLC method. Data were analyzed by independent t test and Pearson's correlation analysis. It had been found that the PD patients had low level of antioxidants like vitamin A (p=0.041) and vitamin E (p=0.018) than the healthy controls whereas the change of vitamin C is not significant. It had been found that the MDA content was significantly higher (p<0.05) in PD patients than that of controls. There was no significant difference for the glutathione content between the 2 groups. Pearson's correlation coefficient suggested that there were significant negative correlation between the glutathione level and vitamin C (p=0.013) and a positive correlation between the vitamin E and vitamin A (p=0.020) in patient group. Our study reveals that panic disorder patients have considerably higher level of MDA, lower level of antioxidant vitamins and glutathione than the healthy control subjects.
