BACKGROUND: Inflammation, oxidative stress, and bioenergetic dysfunction are proposed underlying mechanisms of schizophrenia spectrum disorders (SSDs) and bipolar disorders (BDs), contributing to the largely untreated cognitive and negative symptoms in these conditions. Ketone bodies may offer a therapeutic option for these symptoms through their positive effects on the aforementioned mechanisms. Exogenous ketones like ketone esters (KEs) provide a means to quickly induce ketosis without dietary restrictions, though their effects on SSD and BD have not yet been investigated.
OBJECTIVES: This ongoing triple-blind, randomized controlled crossover trial investigates the effects of a single ingestion of KE on signs and symptoms of SSD and BD.
METHODS: A total of 24 patients (12 SSD and 12 BD) receiving inpatient care at Amsterdam University Medical Center (UMC) will be included in the study. Patients will ingest a single dose of KE ((R)-3-hydroxybutyl-(R)-3-hydroxybutyrate deltaG Ketones (dGK) and an isocaloric carbohydrate control with a washout period of 3 days between drinks. The primary outcome is the change in prepulse inhibition of the startle reflex induced by dGK ingestion compared with control. Secondary outcomes include resting-state electroencephalography, P3B amplitude, cognitive performance, and metabolic, immune, oxidative stress, and circadian rhythm parameters. Feasibility and potential side effects will also be assessed.
RESULTS: N/A (study protocol).
CONCLUSIONS: Our current study will offer valuable preliminary data on the effects of KE in patients with SSD and BD. It can provide the foundation for future research into the therapeutic potential of KE in alleviating symptoms and improving functional outcomes in these disorders.This trial was registered at www.clinicaltrials.gov as NCT06426134.
