Objective:

To describe seizure outcomes and tolerability after PER administration in pediatric patients with AE-related seizures and epilepsy, highlighting the significance of this study due to limited existing data.

Key Findings:
  • In the ASSAE group, 42.8% of patients achieved seizure resolution during the acute phase (3 out of 7).
  • In the AAE group, 57.1% of patients achieved a ≥ 50% reduction in seizure frequency at the 3-month endpoint (4 out of 7).
  • 42.8% of patients in the AAE group achieved seizure freedom at the 3-month endpoint (3 out of 7).
  • No serious adverse events were reported in either group.
Interpretation:

Seizure improvement was observed in some pediatric patients with AE-related seizures or epilepsy after PER administration, without serious adverse events, suggesting potential for clinical application.

Limitations:
  • Small sample size limits the generalizability of findings.
  • Most patients received concomitant ASMs and immunotherapy, complicating the attribution of outcomes to PER.
  • Retrospective nature may introduce biases affecting the results.
Conclusion:

Findings should be interpreted as preliminary and hypothesis-generating, indicating a need for further research to validate these results.
