8-OHdG and Oxidative Stress in Febrile Seizures
Serum 8-Hydroxy-2'-Deoxyguanosine (8-OHdG) and Oxidative DNA Damage in Children With Simple and Complex Febrile Seizures: An Exploratory Prospective Case-Control Study
연구 개요
상태
상세 설명
Febrile seizures are the most common convulsive events of early childhood. Oxidative stress contributes to seizure-induced neuronal injury, but clinical data on oxidative DNA damage across febrile seizure subtypes are limited. This single-centre, prospective case-control study was conducted at the paediatric emergency department of Kayseri City Training and Research Hospital between September and December 2021.
Participants were allocated to three groups: children with a simple febrile seizure, children with a complex febrile seizure, and age- and sex-matched healthy controls. After enrolment, a single venous blood sample was obtained from each child within 24 hours of seizure onset (or at presentation for controls). Serum was separated and stored at -80 °C until analysis.
Serum 8-hydroxy-2'-deoxyguanosine (8-OHdG) was quantified by a commercial enzyme-linked immunosorbent assay (ELISA), with all samples measured in duplicate. Routine laboratory parameters-white-cell count, haemoglobin, and C-reactive protein-and body temperature were recorded concurrently.
Serum 8-OHdG concentrations were compared among the three groups, and the ability of 8-OHdG to discriminate febrile seizure subtypes was explored. Pre-specified subgroup analyses examined complex febrile seizure patients with versus without febrile status epilepticus, and the relationship between 8-OHdG and inflammatory markers. The analysis was framed as exploratory; the study was not powered to validate 8-OHdG as a diagnostic test.

Group 1 Health Controls
Healthy controls (afebrile) n:57 Serum 8-OHdG measurement
|
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
Simple febrile seizure (SFC) n:50 Serum 8-OHdG measurement
|
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
Complex febrile seizure (CFC) n:49 Serum 8-OHdG measurement
|
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.
