Successful control with bromide of two patients with malignant migrating partial seizures in infancy
1Department of Pediatrics, Kansai Medical University, Moriguchi, Japan.
Abstract:
A 3-month-old male and a 4-month-old female infant with intractable seizures were diagnosed as having malignant migrating partial seizures in infancy (MMPSI) with developmental arrest on the basis of characteristics of symptoms, clinical courses and EEGs. We treated these two patients with potassium bromide (80 mg/kg) after conventional antiepileptic drugs failed to adequately control the seizures. The potassium bromide therapy resulted in complete control of seizures in one patient, and more than 95% reduction in seizure frequency in the other.
Insights
Potassium bromide effectively treated malignant migrating partial seizures in infancy (MMPSI), a severe epilepsy condition. This treatment led to complete seizure control in one infant and significant reduction in another.
Area of Science:
- Pediatric Neurology
- Epileptology
- Clinical Pharmacology
Background:
- Malignant migrating partial seizures in infancy (MMPSI) is a rare and severe form of epilepsy characterized by intractable seizures and developmental arrest.
- Conventional antiepileptic drugs often prove ineffective in managing MMPSI, necessitating exploration of alternative therapeutic strategies.
Observation:
- Two infants, a 3-month-old male and a 4-month-old female, presented with intractable seizures and were diagnosed with MMPSI based on clinical symptoms, disease progression, and EEG findings.
- Standard antiepileptic treatments failed to provide adequate seizure control in both patients.
Findings:
- Treatment with potassium bromide at a dosage of 80 mg/kg was administered to both infants after the failure of conventional therapies.
- Potassium bromide therapy resulted in complete cessation of seizures in one infant and a reduction of over 95% in seizure frequency in the other.
Implications:
- Potassium bromide demonstrates significant efficacy as a therapeutic option for infants diagnosed with malignant migrating partial seizures in infancy.
- This finding suggests that potassium bromide may be a valuable addition to the treatment armamentarium for refractory infantile epilepsy syndromes.
- Further research is warranted to establish optimal dosing, long-term efficacy, and safety profiles of potassium bromide in this pediatric population.
