This research is being done to observe the safety, tolerability, side effects, and effectiveness of the ketogenic diet in people with continuous seizures (status epilepticus) being treated in a neurointensive care unit.

Condition Intervention
Status Epilepticus Seizure Epilepsy Refractory Status Epilepticus Medically Resistant Status Epilepticus Dietary Supplement: Ketogenic diet

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Feasibility and Tolerability of the Ketogenic Diet in the Treatment of Refractory Status Epilepticus in a Neurointensive Care Unit.

Further study details as provided by Mackenzie Cervenka, Johns Hopkins University:

Primary Outcome Measures:
  • Feasibility [ Time Frame: 2 weeks ]
    Whether or not the diet protocol was followed

Secondary Outcome Measures:
  • Time to seizure reduction [ Time Frame: Participants will be followed for the duration of the hospital stay, an expected average of 6 weeks ]
    The time (in days) from initiation of the diet to > 50% reduction in frequency and to resolution of electrographic (based on continuous EEG findings) and/or clinical seizures will be recorded.

  • Ranking of tolerability measures on a 10 point scale [ Time Frame: 6 months ]
    Participants will complete a scale ranking convenience, taste, texture, tolerance

  • Number of participants with adverse events and description of events [ Time Frame: 6 months ]
    Reported side effects will be recorded as well as number of patients who develop side effects.

  • Time to achieving serum and/or urinary ketosis [ Time Frame: Until serum or urinary ketosis is achieved, an expected average of 2 weeks ]
    The time (in days) from starting the ketogenic diet to achieving urinary and/or serum ketosis will be recorded.

Enrollment: 15
Study Start Date: November 2012
Study Completion Date: March 2017
Primary Completion Date: March 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Ketogenic diet
Patients will receive the ketogenic diet as a formula delivered via feeding tube. Once able to tolerate food by mouth, patients will be switched to a modified Atkins diet.
Dietary Supplement: Ketogenic diet
4:1 ratio fat: carbohydrates and protein ketogenic liquid via enteral feed
Other Name: KetoCal 4:1 liquid

Exclusion Criteria:

  1. Unstable metabolic condition
  2. Hemodynamic or cardiorespiratory instability
  3. Coagulopathy
  4. Liver failure
  5. Total cholesterol > 300 mg/dL
  6. Inability to tolerate enteral feeds, including ileus
