{Abstract}: OBJECTIVE: Ketogenic metabolic therapy (KMT) has demonstrated effectiveness in seizure reduction. However, patient compliance and adverse effects limit its use. Ready-to-feed (RTF) ketogenic formulas improve compliance and include components that mitigate adverse effects. This study is the first to evaluate the efficacy and tolerability of an RTF, whey-based, medium-chain triglyceride-enhanced (WBME) ketogenic formula.
METHODS: Retrospective data from patients who received KMT between January 1, 2015, and February 28, 2018, were analyzed. Patients who received ≥75% of their total calories from the WBME formula and who were monitored for 3 months were included. Outcome measures were gastrointestinal issues, acidosis, serum blood glucose and beta-hydroxybutyrate levels, unintentional weight changes, diet response (≥50% reduction in seizures), seizure freedom, and change in formula or discontinuation of therapy. Patients with incomplete outcome data or who received <75% of total calories from the formula were excluded.
RESULTS: Twenty-six patients (13 males; mean [SD] age, 6.1 [5.8] years) met the inclusion criteria. Thirteen patients were established patients who received a standard ketogenic formula before changing to the WBME formula; 13 were patients new to KMT whose therapy was initiated using the WBME formula. This formula was well tolerated; no patient in either group discontinued therapy or required a change in formula. The combined diet response rate (95% CI) for established and new patients was 96% (80-100%). Seizure-freedom (95% CI) for both groups at 3 months posttreatment was 20% (7-41%). The most prevalent adverse effect was constipation (69% [95% CI, 48-86%]).
CONCLUSIONS: The WBME ketogenic formula appears to be effective and well tolerated by pediatric patients with refractory epilepsy.
