Serum Thiol-disulphide Levels in Epileptic Pediatric Patients

Background: Epilepsy is a serious clinical condition characterized by recurrent seizures. Oxidative stress plays an important role in the etio-pathogenesis of epilepsy. Measurements of serum thiol and disulfide levels were used to evaluate the antioxidant status of the body Objective: The aim of this study was to determine serum levels of thiol and disulfide in epileptic pediatric patients. Methods: Ninety patients, 54 epilepsy and 36 controls were included in the study. Serum levels of native thiol total thiol and disulfide were measured and disulfide/native, disulfide / total thiol and native thiol/ total thiol ratios were calculated. Hence, the ratios of disulfide/ native thiol, disulfide / total thiol and native thiol/ total thiol were calculated. Results: Serum levels of native thiol, total thiol and disulfide were significantly lower in the epilepsy group than the control group. The ratio of disulfide/native thiol and disulfide / total thiol were significantly higher in the study group than the control group. As well as, the native thiol / total thiol ratio was lower in the epilepsy group than the control group. Native thiol, total thiol and disulfide were significantly lower in the epilepsy group who were taking anti-epileptic drugs than those who were not taking anti-epileptic drugs. Conclusion: We demonstrated a meaningful relationship between oxidative stress markers and epilepsy in pediatric patients.
