The modified Atkins diet for intractable epilepsy may be associated with late-onset egg-induced anaphylactic reaction: a case report.

Abstract

The modified Atkins diet is a therapeutic option for children with intractable epilepsy. It is less restrictive than the traditional ketogenic diet, with ≈60% of calories from fat sources. We describe a 6-y-old boy with intractable epilepsy treated with the modified Atkins diet who presented to the emergency department with first-time anaphylactic reaction to egg. Symptoms of urticaria and angioedema, shortness of breath, wheezing, and cyanosis developed several minutes after he ate a hard-boiled egg. His history was remarkable for asthma, but no food allergies were documented. The anaphylactic reaction appeared after 6 mo of treatment with the modified Atkins diet (including 10-15 eggs daily), which ameliorated his seizures, and was preceded by streptococcal pharyngitis. Laboratory workup revealed specific immunoglobulin E antibodies to egg. This is the first report of new-onset egg allergy in a child, probably triggered by the high egg content of the modified Atkins diet. The risk of egg allergy should be kept in mind when treating epileptic children with the modified Atkins diet, especially those with comorbid asthma.
