Insights
Children with febrile seizures (FS) show an altered thiol/disulphide balance. This suggests that oxidative stress may play a role in the pathogenesis of febrile seizures in pediatric patients.
Area of Science:
- Biochemistry
- Pediatric Neurology
Background:
- Febrile seizure (FS) is the most common seizure type in children.
- The underlying mechanisms of FS remain incompletely understood.
Purpose of the Study:
- To investigate the thiol/disulphide balance in children diagnosed with febrile seizures.
- To explore the potential role of oxidative stress in FS pathogenesis.
Main Methods:
- Compared 40 children with FS to 40 age and gender-matched controls.
- Measured total thiol, native thiol, and disulphide levels.
- Calculated thiol/disulphide ratios.
Main Results:
- Native thiol levels were significantly lower in the FS group compared to controls (p=0.031).
- Disulphide levels and disulphide/native thiol ratios were significantly higher in the FS group.
- A shift in thiol/disulphide balance towards oxidants was observed in children with FS.
Conclusions:
- The altered thiol/disulphide balance in FS suggests a potential role for oxidants in the condition's development.
- Findings indicate that oxidative stress may be implicated in the pathogenesis of febrile seizures.
Purpose:
Febrile seizure (FS) is the most common type of seizure in children and its etiopathogenesis is still not fully understood. We aimed to investigate the thiol/disulphide balance in children who had experienced FS in our study.
Methods:
We included 40 FS and 40 control group subjects in the study. The total thiol, native thiol, and disulphide levels were measured and the disulphide/native thiol, disulphide/total thiol and native thiol/total thiol ratios were calculated in both groups.
Results:
The mean age and gender distribution of the patients and control group subjects were similar. The total thiol level was lower in the FS group than the control group with no statistical significance (p = 0.123). Native thiol was significantly lower in the FS group than the control group (p = 0.031). The disulphide level and the disulphide/native thiol and disulphide/total thiol ratios were statistically significantly higher in the FS group than the control group while the native thiol/total thiol ratio was lower.
Conclusion:
The fact that the disulphide level was higher and the native thiol level lower in the FS group than the control group suggests that the thiol/disulphide balance may have shifted in favor of oxidants and that oxidants may have a role in FS pathogenesis.

Seizures: Classification
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
