Insights
Intravenous levetiracetam effectively treated refractory status epilepticus in two infants with migrating partial seizures in infancy (MPSI). The treatment was well-tolerated, preventing seizure recurrence during follow-up.
Area of Science:
- Pediatric Neurology
- Epileptology
- Clinical Pharmacology
Background:
- Migrating partial seizures in infancy (MPSI) is a rare, severe epileptic syndrome.
- Refractory status epilepticus poses a significant treatment challenge in infants.
Observation:
- Two infants with MPSI and refractory status epilepticus were treated with intravenous levetiracetam.
- Continuous video-electroencephalography (EEG) monitoring was used before, during, and after treatment.
- Comprehensive blood tests were performed to assess safety and tolerability.
Findings:
- Intravenous levetiracetam successfully terminated status epilepticus in both infants.
- The treatment prevented recurrent status epilepticus during the follow-up period.
- No adverse reactions were observed during or after levetiracetam administration.
Implications:
- Intravenous levetiracetam is a promising therapeutic option for status epilepticus in MPSI.
- This study highlights the efficacy and safety of levetiracetam in a challenging pediatric epilepsy syndrome.
- Further research is warranted to confirm these findings in a larger cohort.
Objective:
To evaluate the efficacy and tolerability of intravenous (IV) levetiracetam in refractory status epilepticus of migrating partial seizures in infancy (MPSI).
Methods:
IV levetiracetam was infused in two infants, first as a loading dose of 60mg/kg in 30min, then at 30mg/kg twice a day. Both infants were continuously monitored with video-EEG before, during and after the drug trial. Blood count, liver enzymes, serum creatinine, ammonia and lactate blood levels were performed repeatedly before and after the IV levetiracetam administration. Follow-up was of 16 and 10 months.
Results:
EEG monitoring allowed the diagnosis of MPSI, showing the typical seizures pattern in both patients. IV levetiracetam was effective in stopping status epilepticus in both infants. Levetiracetam also prevented the recurrence of status epilepticus during follow-up. No adverse reactions were observed during the infusion phase or during follow-up.
Conclusions:
MPSI is a newly recognized epileptic syndrome characterized by early onset of intractable partial seizures arisingly independently and sequentially from both hemispheres, migrating from one region of the brain to another and from one hemisphere to another. We report the efficacy of intravenous levetiracetam in resolving refractory status epilepticus in two infants with this new epilepsy syndrome.

Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
