Highlights

  • Ketogenic diet can be conducted in a patient with an additional dietary requirement.

  • Ketogenic diet should not be considered as a last chance treatment even in more complex situation.

  • Ketogenic diet can be helpful in the management of Lennox–Gastaut syndrome.

Abstract

The ketogenic diet is an evidence-based treatment for resistant epilepsy including Lennox–Gastaut syndrome. This diet is based on low carbohydrate-high fat intakes. Dietary treatment is also therapeutic for inborn errors of metabolism such as aminoacdiopathies. We report a child with both Lennox–Gastaut syndrome and tyrosinemia type 1. This epilepsy syndrome resulted form a porencephalic cyst secondary to brain abscesses that occurred during the management of malnutrition due to untreated tyrosinemia type 1. We used a ketogenic diet as treatment for Lennox–Gastaut syndrome taking into account dietary requirements for tyrosinemia type 1. The patient was transiently responder during a 6-month period. This report illustrates that ketogenic diet remains a therapeutic option even when additional dietary requirements are needed.

Case report

A 17-month-old girl was brought to our attention for multiple bleeding (epistaxis, otorrhagia, rectorragie) secondary to liver failure with a previous history of growth and development delays.

She was born from non-consanguineous parents, the last of 4 siblings, without prenatal or birth significant history. She had delayed developmental milestones, demonstrating head control at 5 months of age, sitting with support at 9 months, walking and language not yet acquired.

On examination she had

Discussion

This report illustrates that KD could be used taken into account an additional diet requirement for a metabolic disorder. Because of the pharmacoresistance of a Lennox–Gastaut syndrome in a patient with tyrosinemia type 1, we started tailored KD. We used a KD with restricted phenylalanine and tyrosine intakes. Our aim was to maintain plasma tyrosine levels below 400 μmol/l. This treatment was proposed after the failure of various AED combinations with a particular attention with AEDs known to

    We analyzed four RCTs [39–42], among which one studied the economic evaluation of KD versus usual care in children and adolescents with intractable epilepsy; one analyzed patients with refractory epilepsy aged 1–18 years; one studied the efficacy of the classic KD compared with modified Atkins diets in the refractory childhood epilepsy, and another demonstrated a positive impact of the KD on behavioral and cognitive functioning in children and adolescents with refractory epilepsy. Twelve publications were clinical cases [43–54]: among these, one paper studied the use of KD as a broad-spectrum treatment for super-refractory pediatric status epilepticus in patients aged 9 weeks to 13,5 years. Among the 4 clinical reviews [55–58] we obtained from PubMed, 1/4 showed the results of a project group of 5 experts, performed in 2015, in order to create a consensus statement regarding the clinical management of the KD in infancy; 1/4 analyzed the cost-effectiveness of the KD and VNS for the treatment of children with intractable epilepsy; 1/4 performed the analysis of all nonpharmacological medical treatments in pediatric epilepsies, and the last offered an overview of various diets, comparing their efficacy.
