title: Study of oxidative stress in obsessive compulsive disorder in response to treatment with Fluoxetine.
abstract: Oxidative stress has been found to play important role in several neuropsychiatric diseases including Obsessive Compulsive Disorder. A longitudinal case control study was conducted to evaluate the oxidative stress in 30 newly diagnosed obsessive compulsive disorder patients and same number of control patients. Serum thiobarbituric acid reacting substances, plasma ascorbate were assessed to evaluate oxidative stress and Yale Brown obsessive compulsive scale for disease severity before and after treatment with Fluoxetine at the average dosage of 40 mg/day. Improvement in Yale Brown obsessive compulsive scale score by about 43% after 12 weeks treatment was associated with significantly decreased thiobarbituric acid reacting substances and increased plasma ascorbate values (p < 0.05). The newly diagnosed obsessive compulsive disorder patients had higher serum thiobarbituric acid reacting substances as well as a lower plasma ascorbate levels than the control population. Thus, the present study suggested a significant role of oxidative stress in obsessive compulsive disorder and showed that a successful treatment with Fluoxetine not only improves the clinical scenario but also reduces the oxidative stress that may further improve the prognosis of the disease.
