Abstract

Abstract : Aim: To examine the value of vitreous beta-hydroxybutyrate and serum acetone in the investigation of sudden unexpected death. Methods: Coroners' autopsy reports from a provincial UK city, with a population of approximately 900 000, over a 24-month period with significant ketoacidosis were studied. Demographic features, medical history, anatomical and histological findings, and biochemical parameters, including renal function, vitreous glucose, serum and vitreous alcohol, were analysed. Results: Forty-two cases (28 males and 14 females) were identified; 55% had a history of alcohol and/or substance misuse, and mental health problems, particularly depression and anxiety, and 16% were diabetic. In all, 50% of subjects had alcoholic ketoacidosis (AKA), 19% had diabetic ketoacidosis (DKA) and 12% had a history of both diabetes and alcohol abuse. In 19% of cases, an exact cause of ketoacidosis was established. In AKA, the subjects typically had low vitreous glucose and low or undetected blood alcohol levels. All of the subjects with raised vitreous glucose levels had DKA. Conclusion: Ketoacidosis is relatively common and should be considered as a cause of sudden death, especially in alcoholic patients and patients with diabetes with no clear cause of death at autopsy.
