Considering safety and patient tolerance in the use of ketogenic diet in the management of refractory and super-refractory status epilepticus: a systematic review.

Early use of the ketogenic diet (KD) is described as having a particular interest for super‐refractory status epilepticus and febrile infection-related epilepsy syndrome. The authors conducted a systematic review of the available data on the KD for refractory and super-refractory status epilepticus. Following a systematic bibliographic search, the authors found 15 published papers: 2 prospective and 13 retrospective studies. Most often, the primary aim of the retrospective studies was the efficacy evaluation of the KD for refractory or super-refractory status epilepticus. Four studies focused on the use of KD for NORSE/FIRES. These initial studies suggested that KD was effective in these conditions, and that it showed mild and manageable side effects. The published studies provided enough preliminary data to validate the feasibility and safety of the use of KD for refractory and super-refractory status epilepticus. Further studies demonstrating the efficacy of the KD in these indications are needed. Possible design and endpoints are discussed. [ABSTRACT FROM AUTHOR]
