The investigation of beta-hydroxybutyrate as a marker for sudden death due to hypoglycemia in alcoholics.

The purpose of this study was to determine if the ketone body beta-hydroxybutyrate (beta-HBA) is a useful positive marker for sudden deaths in chronic alcoholics, thought to be due to hypoglycemia. Beta-HBA can be reliably measured in postmortem samples of vitreous humour and urine. In fatalities where there is a history of chronic alcoholism and routine investigations, including autopsy and routine toxicology, yield only a fatty liver as positive findings, a raised level of beta-HBA can be used as an indicator for alcoholic ketosis. Alcoholic ketosis is often associated with antemortem hypoglycemia. Caution should be observed in attributing the significance of ketosis exclusively to alcohol in those conditions where it would otherwise be expected (i.e. diabetic ketoacidosis and chronic starvation). A measurement of this marker of alcoholic ketosis may also help in the investigation of cases where hypothermia or alcohol withdrawal fits are suspected.
