Insights
Levetiracetam effectively reduced seizure frequency in over half of children with refractory epilepsy. This add-on therapy offers a promising treatment option for pediatric patients resistant to conventional antiepileptic drugs.
Area of Science:
- Pediatric Neurology
- Clinical Pharmacology
Background:
- Refractory epilepsy affects approximately 25% of children, leading to significant morbidity and developmental challenges.
- Effective treatment strategies are crucial for managing uncontrolled seizures in pediatric populations.
- Current antiepileptic drugs (AEDs) are ineffective for a substantial number of children with epilepsy.
Purpose of the Study:
- To evaluate the efficacy of levetiracetam as an add-on therapy for children diagnosed with refractory epilepsy.
- To determine the impact of levetiracetam on seizure frequency in pediatric patients unresponsive to standard treatments.
Main Methods:
- A prospective add-on study involving 45 children (aged 0.6-15 years) with refractory epilepsy.
- Levetiracetam was administered as an adjunct to existing antiepileptic drug regimens.
- Dosage ranged from 20mg/kg/day, titrated up to 60mg/kg/day, with a minimum follow-up of 12 weeks.
Main Results:
- Levetiracetam demonstrated efficacy in 54.3% of patients, achieving at least a 50% reduction in seizure frequency.
- 8.7% of children became seizure-free, while 28.3% experienced a 50-74% decrease in seizures.
- No significant correlation was found between treatment outcomes and patient demographics, seizure characteristics, or diagnostic data.
Conclusions:
- Levetiracetam is a viable and effective add-on treatment for pediatric refractory epilepsy.
- The study supports the use of levetiracetam in children who do not respond to conventional antiepileptic drug therapies.
Background:
Epilepsy is a common disease of childhood, in which almost 25% of cases are resistant to common antiepileptic drugs. Uncontrolled epilepsy increases morbidity and mortality rates, adversely affects growth and development in these children and imposes heavy psychological stress and financial burdens on parents, health care and society, making it mandatory to find effective therapies for the condition. Our aim was to study the efficacy of levetiracetam, as an add-on therapy, in children suffering from refractory epilepsy.
Materials And Methods:
In this prospective add-on study, 45 children aged 0.6-15 years (median 5.9 years) with epilepsy not responding to most conventional or new antiepileptic drugs were treated by adding levetiracetam to their present antiepileptic regimen and followed for a minimum period of 12 weeks. The starting dose of 20mg/kg/day was increased at intervals of 1 week by 10mg/kg/day, if necessary, up to a maximum dose of 60mg/kg/day.
Results:
Four children (8.7%) became seizure free, in 4 (8.7%), seizure frequency increased, and in 8 (17.4%) and 13 (28.3%) patients, seizure frequency decreased by 75-99% and 50-74% respectively. Overall levetiracetam was effective in 54.3% of patients, decreasing seizure frequency to at least 50% of baseline seizure frequency. Variables such as sex, age, duration of disease, type and cause of seizure, EEG and imaging data, also type of epileptic syndrome showed no statistically significant correlations with these results.
Conclusion:
Levetiracetam can be used as an effective add-on treatment in children with refractory epilepsy.
