Insights
Certain pediatric epilepsy subgroups, including Malays, females, and those under 4 with developmental delays or focal seizures, show better seizure frequency reduction with antiepileptic drug therapy. Polytherapy was linked to higher seizure frequency.
Area of Science:
- Pediatric Neurology
- Epilepsy Management
- Clinical Outcomes Research
Background:
- Seizure control is paramount in epilepsy management.
- Identifying factors influencing seizure frequency is crucial for effective treatment.
Purpose of the Study:
- To evaluate seizure frequency patterns in pediatric epilepsy patients.
- To explore relationships between seizure frequency, demographics, clinical factors, and treatment outcomes.
Main Methods:
- Retrospective cohort study at a Pediatric Neurology Clinic.
- Data collected over 6 months from medical records using a standardized form.
Main Results:
- No overall association between seizure frequency and demographics/clinical characteristics.
- Significant seizure reduction observed in specific subgroups: Malays, females, <4 years, global developmental delay/intellectual disability, and focal seizures.
- Polytherapy associated with higher seizure frequency and increased likelihood of supra-therapeutic antiepileptic drug doses compared to monotherapy.
Conclusions:
- Specific pediatric epilepsy subgroups demonstrate greater responsiveness to antiepileptic drug therapy.
- Subgroups showing better response include Malays, females, younger children (<4 years), those with global developmental delay/intellectual disability, and focal seizures.
Introduction:
Seizure-free patients or substantial reduction in seizure frequency are the most important outcome measures in the management of epilepsy. The study aimed to evaluate the patterns of seizure frequency and its relationship with demographics, clinical characteristics, and outcomes.
Materials And Methods:
A retrospective cohort study was conducted at the Pediatric Neurology Clinic, Hospital Pulau Pinang. Over a period of 6 months, the required data were extracted from the medical records using a pre-designed data collection form.
Results:
Seizure frequency showed no significant association with patient's demographics and clinical characteristic. However, significant reduction in seizure frequency from the baseline to the last follow-up visit was only seen in certain subgroups of patients including Malays, females, patients <4 years of age, patients with global developmental delay/intellectual disability, and patients with focal seizure. There was no significant association between seizure frequency and rate of adverse events. Polytherapy visits were associated with higher seizure frequency than monotherapy visits (27.97 ± 56.66, 10.94 ± 30.96 attack per month, respectively) (P < 0.001). There was a clear tendency to get antiepileptic drugs used at doses above the recommended range in polytherapy (8.4%) rather than in monotherapy (1.4%) visits (P < 0.001). A significant correlation was found between seizure frequency and number of visits per patient per year (r = 0.450, P < 0.001).
Conclusion:
Among children with structural-metabolic epilepsy, Malays, females, patients <4 years of age, patients with global developmental delay/intellectual disability and patients manifested with focal seizure are more responsive antiepileptic drug therapy than the other subgroups of patients.
