Differential Ketogenic Diet-Induced Shift In Csf Lipid/Carbohydrate Metabolome Of Pediatric Epilepsy Patients With Optimal Vs. No Anticonvulsant Response: A Pilot Study, Susan A. Masino, David N. Ruskin, Natalie R. Freedgood, Marie Lindefeldt, Maria Dahlin

Faculty Scholarship

Background: The low carbohydrate, high fat ketogenic diet can be an effective anticonvulsant treatment in some pediatric patients with pharmacoresistant epilepsy. Its mechanism(s) of action, however, remain uncertain. Direct sampling of cerebrospinal fluid before and during metabolic therapy may reveal key changes associated with differential clinical outcomes. We characterized the relationship between seizure responsiveness and changes in lipid and carbohydrate metabolites. Methods: We performed metabolomic analysis of cerebrospinal fluid samples taken before and during ketogenic diet treatment in patients with optimal response (100% seizure remission) and patients with no response (no seizure improvement) to search for differential diet effects in …
