Potential Role of Perampanel in Reducing Barbiturate Dependency in Febrile Infection-Related Epilepsy Syndrome: A...

Area of Science:

• Neurology
• Pediatric Neurology
• Epileptology

Background:

• Febrile infection-related epilepsy syndrome (FIRES) is a rare, severe neurological disorder in children, characterized by refractory status epilepticus.
• Standard antiepileptic drugs (AEDs) are often ineffective, leading to the use of high-dose anesthetics and mechanical ventilation, associated with significant morbidity.
• The therapeutic role of perampanel, an AED, in FIRES remains largely uninvestigated.

Observation:

• A 13-year-old boy presented with FIRES following a febrile illness, experiencing refractory status epilepticus.
• Initial treatment with AEDs failed, necessitating high-dose thiopental and ventilator support.
• Perampanel was initiated and titrated, leading to successful barbiturate weaning and extubation.

Findings:

• Perampanel administration facilitated the discontinuation of thiopental and mechanical ventilation in a pediatric FIRES case.
• The patient achieved seizure freedom with adjunctive therapy including clobazam and levetiracetam.
• Neuroimaging revealed bilateral hippocampal atrophy, correlating with persistent memory and behavioral deficits post-treatment.

Implications:

• Perampanel may offer a valuable therapeutic option for managing FIRES, potentially mitigating the risks associated with prolonged barbiturate anesthesia.
• Despite cognitive sequelae, perampanel demonstrated a favorable safety profile in this case, suggesting its utility in refractory epilepsy syndromes.
• Further research is warranted to establish the efficacy and safety of perampanel in a larger cohort of FIRES patients.
