Does a Ketogenic Dietary Supplement Reduce Alcohol Withdrawal Symptoms in Humans? (KME)
The Ketone Mono Ester Study - Does a Ketogenic Dietary Supplement Reduce Alcohol Withdrawal Symptoms in Humans
A ketogenic diet (KD) is high in fat and low in carbohydrates and induces ketosis. KD is an approved non-pharmacological therapy for drug-resistant child epilepsy. Research has shown that a KD can reduce the behavioral measures of alcohol withdrawal symptomatology in rats. Ketosis is also possible to achieve without adherence to a KD, by ingestion of a ketogenic dietary supplement. In this study, we want to investigate if the attenuating effect of the KD observed in rodents, is also applicable in humans, i.e. whether a ketogenic dietary supplement, here a ketone monoester, would be effective in suppressing alcohol withdrawal symptoms in humans.
Objective:
To test the effect of a ketogenic dietary supplement on the need for benzodiazepines in managing alcohol withdrawal syndrome in humans.
Eligibility:
Adults 18-70 years who are alcohol dependent and are seeking treatment for alcohol withdrawal syndrome in an out-patient setting.
Design:
Double blinded, randomized clinical trial. The participants will be randomized to receive either the ketone ester beverage, or a placebo beverage.
The study will be conducted over three days (72 hours), with follow-up at 1 month and 1 year after completion. A sub-set of patients will undergo Magnetic Resonance Spectroscopy (MRS) following withdrawal treatment, and again after 1 month.

Detailed Description
Neuroimaging studies have shown that acute alcohol administration decreases glucose metabolism in the human brain, which was initially thought to reflect decreased brain function. However, subsequent studies showed that even low doses of alcohol, with minimal behavioral effects, also decreased baseline brain glucose metabolism and further. This led to the hypothesis that the reduction in brain glucose metabolism during alcohol intoxication reflected the brain's utilization of an alternate energy substrate, e.g. the alcohol metabolite acetate. Acetate is not a ketone body, but biochemically similar to the ketone bodies, which include acetoacetate, BHB and acetone. Ketone bodies are similarly taken up by the Monocarboxylate Transporters in neurons, and other brain tissue. A pre-clinical trial has demonstrated that the implementation of a KD for 10 days significantly reduced the behavioral measures of alcohol withdrawal symptomatology in rats. In this study, we want to investigate if the attenuating effect of the KD observed in rodents, is also applicable in humans, i.e. whether a ketogenic dietary supplement, here a ketone monoester, would be effective in suppressing alcohol withdrawal symptoms in humans.
Objectives:
We will investigate the effect of a five times daily oral administration of a ketone dietary supplement beverage vs. placebo on the need for benzodiazepines in alcohol withdrawal syndrome. The KME beverage is a supplement to standardized out-patient alcohol withdrawal treatment.
Study population:
36 participants aged 18-70 with a diagnosis of alcohol use disorder according to the DSM-V, ICD-10, and a previous history of treatment-requiring alcohol withdrawal syndrome.
Design:
Clinical double-blinded, randomized, placebo-controlled, three-day clinical trial, with an MRS (Magnetic Resonance Spectroscopy) sub-study. The participants will be randomized to receive either the ketone ester beverage, or a placebo beverage 5 times daily. Participants will be asked to register benzodiazepine use in a medication-diary during the study. Participants will be asked to self-monitor blood-glucose and ketone levels by use of fingerstick measurements. During the study patients will be evaluated for withdrawal severity, and complete questionnaires on alcohol craving, sleep, anxiety and mood.

Mood, assessed by the Major Depression Inventory scale, MDI. The MDI is a self report mood questionnaire. Symptoms are rated based on how the patient has been feeling over the past two weeks. The diagnostic demarcation line indicates at which point a symptom is severe enough to be used in the DSM-IV diagnostic algorithm of major depression. Each question has a point giving system from 0-5 points. The higher the score, the more severe outcome. Scores from 20-24 indicates minor depressive symptoms. Scores from 25-29 indicates a moderate depression. Scores from 30 and above indicates major depressive symptoms. |
