Özet

Background: Epilepsy is one of the most common neurological diseases. The underlying pathophysiological mechanisms in epilepsy are still unknown. Oxidative stress is believed to be one of the factors involved in the pathogenesis of epileptogenesis. In various pathophysiological conditions, reactive nitrogen species (RNS) such as nitrogen and peroxynitrite are produced and these RNSs can bind to free nucleosides and nucleotides or to nucleosides and nucleotides existing in the DNA/RNA structure. 8-Nitroguanine (8-NG) is a typical DNA nucleobase product of nitrosative damage generated by RNS. It has been proposed that F2-isoprostanes, in particular 8-iso-Prostaglandin F2a (8-isoPGF2a), are specific, reliable and non-invasive biomarkers of lipid peroxidation in vivo. In the present study, we compared the levels of lipid oxidative stress biomarker 8-isoPGF2a and nitrosative stress DNA biomarker 8-NG in patients with epilepsy undergoing antiepileptic drug (AEDs) treatment and with those in healthy participants.
