8-OHdG and Oxidative Stress in Febrile Seizures
Sponsor: Kayseri City Hospital
Summary
This prospective case-control study investigates whether serum 8-hydroxy-2'-deoxyguanosine (8-OHdG), an established biomarker of reactive oxygen species-mediated DNA oxidation, is elevated in children with febrile seizures compared with healthy children, and whether it differs between simple and complex febrile seizure subtypes. Children presenting with a febrile seizure and age-matched healthy controls have serum 8-OHdG measured within 24 hours of seizure onset, alongside routine inflammatory markers (white-cell count, C-reactive protein) and haemoglobin. The primary aim is to determine whether acute oxidative DNA damage is detectable after febrile seizures and whether 8-OHdG levels distinguish simple from complex subtypes. The study is exploratory and hypothesis-generating; it is not designed to establish 8-OHdG as a clinically applicable diagnostic biomarker.

Interventions
Group 1 Health Controls
Single venous blood sample obtained from each participant; serum 8-hydroxy-2'-deoxyguanosine (8-OHdG) was measured by enzyme-linked immunosorbent assay (ELISA) within 24 hours of seizure onset. This was an observational measurement only; no therapeutic intervention was administered.
Group 2 SFC
Single venous blood sample obtained from each participant; serum 8-hydroxy-2'-deoxyguanosine (8-OHdG) was measured by enzyme-linked immunosorbent assay (ELISA) within 24 hours of seizure onset. This was an observational measurement only; no therapeutic intervention was administered.
Group 3 CFC
Single venous blood sample obtained from each participant; serum 8-hydroxy-2'-deoxyguanosine (8-OHdG) was measured by ELISA within 24 hours of seizure onset. The same measurement was performed in all three groups (healthy controls, simple febrile seizure, and complex febrile seizure). This was an observational measurement only; no therapeutic intervention was administered.
