Insights
Phenobarbital and phenytoin are effective first-line treatments for childhood epilepsy, improving seizure control. Vitamin D supplementation also supports seizure management in some cases.
Area of Science:
- Pediatric Neurology
- Epileptology
- Pharmacotherapy
Background:
- Epilepsy is a neurological disorder characterized by recurrent seizures.
- Optimizing frontline antiepileptic drug (AED) therapy is crucial for managing childhood epilepsy.
- Phenobarbital and phenytoin are established AEDs with potential for frontline use.
Purpose of the Study:
- To evaluate the efficacy of phenobarbital and/or phenytoin as frontline treatments for childhood epilepsy.
- To assess the impact of these AEDs on seizure control and drug utilization.
- To determine the role of vitamin D in managing breakthrough seizures.
Main Methods:
- A before-and-after study design was employed at a pediatric outpatient epilepsy clinic.
- Patient data from two cohorts (pre- and post-protocol) were compared.
- Etiology was investigated using EEG and CT scans; serum calcium, phosphorus, and alkaline phosphatase levels were assessed.
Main Results:
- Good seizure control improved to 84.8% post-intervention, with phenobarbital/phenytoin use increasing significantly.
- Seven of eight children with breakthrough seizures remained seizure-free after vitamin D administration.
- Thirteen of nineteen children on polytherapy were successfully switched to phenobarbital/phenytoin.
Conclusions:
- Phenobarbital and/or phenytoin are effective frontline AEDs for childhood epilepsy.
- Vitamin D administration plays a supportive role in managing certain seizure presentations.
- This study supports the optimized use of phenobarbital and/or phenytoin in pediatric epilepsy management.
Objective:
To optimize the use of phenobarbital and/or phenytoin as frontline drugs for treatment of childhood epilepsy.
Design:
Before-and -after study.
Setting:
Epilepsy clinic at paediatric OPD, Sassoon General Hospital, Pune.
Materials And Methods:
Epilepsy is a condition in which seizures are triggered recurrently from within the brain. For epidemiological classification purpose epilepsy is considered to be present when two or more unprovoked seizures occur at an interval greater than twenty four hours apart. Seizures were classified as generalized and partial seizures, with underlying etiology investigated with EEG, CT scan in majority of the patients. Follow - up rate, seizure - control and antiepileptic drugs used among 151 children enrolled as on 31 March 2005 were compared with 106 children with new onset epilepsy enrolled as on February 2006. Eight children with breakthrough convulsion after a seizure free period of five to eighteen months were followed up after injection vitamin D. Nineteen children with poor control of seizures receiving polytherapy with newer antiepileptic drugs were assessed with frontline antiepileptic medication of phenobarbital and/or phenytoin. Serum calcium, phosphorus, alkaline phosphatase were done in seventy two consecutive children with seizure disorder.
Results:
During post protocol period good seizure control was achieved in 84.8% as against 80.7% and use of phenobarbital and/or phenytoin increased to 65.11% from 22.87%. Of the 8 cases with breakthrough seizures seven remained seizure free after vitamin D administration and with no dose enhancement of AED medications of the nineteen. Children receiving polytherapy thirteen children could be successfully switched to phenobarbital and/or phenytoin. Forty four (61%) children had hypocalcemia (less than 9 mg%), fifty seven (79%) children had raised alkaline phosphatase levels (more than 270 IU).
Comments:
Phenobarbital and/or phenytoin have been found to be effective frontline AED. Periodic administration of vitamin D plays a supportive role.
