Ketogenic diet for treatment of infantile spasms

Area of Science:

• Neurology
• Pediatric Epilepsy
• Nutritional Therapy

Background:

• Infantile spasms (IS) are a severe epilepsy syndrome in infants.
• Catastrophic IS often presents treatment challenges.
• Previous ketogenic diet (KD) protocols had limitations.

Purpose of the Study:

• To evaluate the efficacy, tolerability, and safety of a revised ketogenic diet (KD) protocol for infantile spasms (IS).
• To assess the impact of KD on seizure frequency, EEG, and neurological development in children with IS.

Main Methods:

• Retrospective analysis of 43 children with catastrophic IS treated with a revised KD.
• Data collected from June 1995 to May 2004 across two Korean epilepsy centers.
• Outcomes included seizure frequency, EEG, adverse events, and neurodevelopmental progress.

Main Results:

• 53.5% of patients achieved a seizure-free state.
• 62.8% experienced over a 90% reduction in seizure frequency.
• Improvements in EEG and neurological development were concordant with seizure control.
• The revised protocol, featuring a non-fasting start, 8-month trial, 3:1 lipid-to-non-lipid ratio, and liquid formula, enhanced tolerability and safety.
• Most complications were transient, indicating good overall tolerance.

Conclusions:

• The revised ketogenic diet is an effective alternative therapy for catastrophic infantile spasms.
• The modified protocol improves the safety and comfort of KD treatment.
• Further refinements to the KD protocol may yield additional benefits for IS management.
