OBJECTIVES: To measure and compare the efficacy and tolerability of a classical ketogenic diet (CKD) and a polyunsaturated fatty acids ketogenic diet (PUFAKD) in managing childhood refractory epilepsy. Efficacy was assessed by measuring the change in seizure frequency at 3, 6, 9, and 12 months within and between groups. The percentage reduction in seizures at <50 %, 50-90 %, >90 %, and 100 % was also measured. Tolerability was assessed and compared by recording adverse events - vomiting, nausea, lethargy, and constipation.
METHODS: 52 children, aged 2-10 years, were randomized, 25 in the CKD group and 27 in the PUFAKD group. Fat: carbohydrate + protein ratio of 2.2:1-4:1 was maintained in both diets; the PUFAKD group only used unsaturated fats with an omega 3: omega 6 ratio of 1:2.8. Ketone levels were measured using keto-dipsticks, with 4+ and 4++ (80-160 mg/dL) being the most optimal values.
RESULTS: A significant decrease (p=0.001) in seizures was observed (n=52), with no significant difference (p=0.537) between the two groups. The mean seizure reduction was 71.1 %, with no significant difference (p=0.488) in both groups. The mean compliance rate was 78.3 % (n=52). A statistically significant linear trend existed between a higher compliance rate and a greater reduction in seizures (p = 0.042, Z=4.039) among all children (n=52). Nausea (p=0.033) and vomiting (p=0.014) occurred more in PUFAKD than in CKD.
CONCLUSION: No significant difference was seen in seizure reduction between the two groups. Compliance correlates with a greater seizure reduction. Despite similar seizure reduction rates, the novel PUFAKD exhibited poorer compliance and more pronounced adverse effects compared to CKD. CKD remained a superior choice over the novel PUFAKD in the management of paediatric refractory epilepsy. More controlled trials with varying PUFA compositions are recommended for long-term evaluations.
