Abstract

Objectives This case-control study was carried out to compare serum total antioxidant capacity (TAC) in the newly diagnosed children with epilepsy and that of a control group of healthy children at the same age and probable effects of antiseizure medications prescription on it. Materials & Methods Overall, 130 participants (65 in each group) aged between 1 and 17 yr old were enrolled. The study was conducted in Children’s Medical Center, the Pediatrics Center of Excellence, Tehran, Iran in 2015. Serum TAC test was done for both control and patients group before antiseizure medications therapy and after 3 months of monotherapy with sodium valproate, carbamazepine and phenobarbital in patients. Serum TAC values were measured based on Erel’s method using an automated commercial kit. This method is based on the bleaching of the characteristic color of a more stable 2, 2’-azinobis- (3-ethylbenzothiazoline-6-sulfonic acid) radical cation by antioxidants. The results were expressed in mmol Trolox equivalent/l. Results Serum TAC values were significantly lower in the patients group before drug administration [mean (SD): 1.31 (0.19) mmol/L] in comparison with the control group [mean (SD): 1.46 (0.21) mmol/L] (P<0.001). In the patient’s group, no differences were found in the serum TAC before and 3 months after antiseizure medications monotherapy. Conclusion Reduced serum TAC and an increased vulnerability to oxidative stress should be considered as an etiologic factor in the children with epilepsy. © 2018, Iranian Child Neurology Society.
