Vigabatrin in infantile spasms: preliminary result

Area of Science:

• Pediatric Neurology
• Clinical Pharmacology

Background:

• Infantile spasms are a severe epilepsy syndrome in infants.
• Effective treatment options are crucial for improving outcomes.

Purpose of the Study:

• To assess the efficacy of vigabatrin in treating infantile spasms in Thai children.
• To evaluate treatment response and side effects in this population.

Main Methods:

• A prospective study involving 20 infants under 2 years with infantile spasms.
• Vigabatrin dosage initiated at 35-50 mg/kg/day, with weekly escalation up to 130 mg/kg/day.
• Treatment response assessed by seizure cessation, frequency reduction, and clinical observation.

Main Results:

• Complete seizure control was achieved in 60% (12/20) of patients.
• An additional 30% (6/20) experienced at least a 50% reduction in seizure frequency.
• One patient developed reversible orofacial dyskinesis; vision evaluations were unremarkable.

Conclusions:

• Vigabatrin demonstrates significant efficacy in treating infantile spasms in Thai children.
• Long-term follow-up is recommended to monitor sustained efficacy and potential adverse events.
