Isopropanol has been identified in five acetonemic patients not exposed to this compound. Serum concentrations ranged up to 297 mg/L for IPA and up to 321 mg/L for acetone. Concentration ratios (isopropanol:acetone) ranged up to 5.12. All five patients had Type I diabetes mellitus and were insulin-dependent. At the time isopropanol was detected each patient was hyperglycemic, and four patients were acidotic. These findings tend to corroborate clinically some earlier autopsy reports that acetone may be converted to isopropanol in physiological conditions in which reduced nicotinamide adenine dinucleotide is elevated. The conversion of acetone to isopropanol in vivo has significant clinical and forensic toxicological implications.

    ABSTRACT: The case is presented of a 34-year-old man, an insulin-dependent diabetic, who was found decomposed in his apartment. The victim had been recently discharged from a mental hospital and was to be monitored by the community's mental health personnel. While the autopsy revealed little in the way of disease, toxicological studies yielded a blood acetone level of 0.070 g/dl and a urine acetone level of 0.086 g/dl. The medical examiner ruled the cause of death diabetic ketoacidosis. To support this conclusion in the absence of a vitreous humor glucose concentration, 18 well-documented cases of diabetic ketoacidosis were reviewed, and acetone concentrations were compared with the acetone concentrations found in the presented case.

    ABSTRACT: A 29-year-old man presented to the Emergency Department with acute mental status changes. He was unable to give a history. He was found to be in diabetic ketoacidosis, although his family reported no prior history of diabetes. A toxic exposure work-up revealed the presence of isopropyl alcohol in the patient’s blood. His condition improved with treatment of the ketoacidosis, and he subsequently denied any exposure to isopropyl alcohol prior to presentation to the hospital. This case provides further support to a growing body of evidence that the detection of isopropyl alcohol may not represent an acute ingestion but, rather, a byproduct of acetone metabolism in certain disease states.
