Acetoacetate and beta-hydroxybutyrate formation in alcoholic ketoacidosis has several causes. It also occurs in response to starvation and the extracellular fluid volume depletion arising from vomiting, decreased fluid intake and inhibition of antidiuretic hormone secretion by alcohol. Moreover, dehydration and volume contraction impair the excretion of ketones by the kidneys, leading to further elevation in ketone levels.

• Severe metabolic disturbances including high levels of free fatty acids do probably play a major role due to the effect on the Krebs Cycle.
• However, after adequate treatment, it is equally essential to refer the patient to alcohol abuse rehabilitation programs to prevent recurrence and long-term irreversible damage from alcohol abuse.
• Alcoholic ketoacidosis is a recognised acute complication in alcohol dependent patients.
• Specimens for microbiology were collected from at least two different sampling sites and always included cardiac blood and cerebrospinal fluid.
• Most of the time the cause of death becomes clear from autopsies, histological, alcoholimetric and toxicological tests, but in a smaller number of cases it remains indeterminate even after these procedures.
• The key tenants to management of AKA include fluid resuscitation and electrolyte correction.
• Examination should reveal a clear level of consciousness, generalised abdominal tenderness (without peritoneal signs), and tachypnoea.

It can be difficult at presentation to distinguish between ethanol, methanol and ethylene glycol toxicity in an alcoholic patient with an increased anion gap, metabolic acidosis and a higher serum osmolal gap. Additional diagnostic possibilities, which may be concurrent abnormalities, include lactic acidosis and diabetic ketoacidosis (Höjer, 1996; Tanaka et al., 2004; McGuire et al., 2006). Main laboratory findings reflect the severity of the ketoacidosis as well as that of fluid and alcoholic ketoacidosis electrolyte disturbances secondary to vomiting and dehydration (Fulop, 1993). The syndrome arises through the various metabolic effects of alcohol in the fasted, volume-depleted, alcoholic who has abruptly stopped his alcohol intake. The ketoacids responsible for alcoholic ketoacidosis (beta-hydroxybutyrate and acetoacetate) are in part formed because of the metabolism of ethanol in the liver. Ethanol is oxidized to acetaldehyde in the liver cytoplasm by alcohol dehydrogenase.

Sudden Unexpected Death in Alcohol Misuse—An Unrecognized Public Health Issue?

Subsequent mismanagement can lead to increasing morbidity and mortality for patients. AKA typically presents with a severe metabolic acidosis with a raised anion gap and electrolyte abnormalities, which are treatable if recognized early and appropriate management instituted. Given the increasing epidemic of alcohol-related healthcare admissions, this is an important condition to recognize and we aim to offer guidance on how to approach similar cases for the practising clinician. On physical examination, beyond the typical signs of chronic alcohol abuse, these patients may present hyperventilation, tachycardia, hypotension and signs of dehydration due to the decreased fluid intake and severe vomiting described above.

Alcoholic ketoacidosis: review of current practice and association of treatments to improvement

Acetaldehyde is metabolized further to acetic acid by aldehyde dehydrogenase. Both steps require the reduction of nicotinamide adenine dinucleotide (NAD+) to reduced nicotinamide adenine dinucleotide (NADH). Sodium and chloride were analyzed in vitreous stored in preservative-free tubes on the Roche Modular P clinical chemistry system. Concentrations were determined by an indirect potentiometry assay (ion selective-electrode using indirect potentiometry). Alternative causes of death were excluded based on all postmortem investigation results.

The relationship between alcohol and coronary heart disease has been the subject of recent media coverage in the UK due to a study published by Arriola et al. which found that moderate, high or very high alcohol intake by men reduces their risk of coronary heart disease by more than 30% [27]. Interestingly, despite this, ischaemic heart disease in this study was still the single commonest cause of death in the alcohol excess group accounting for 16.7% of deaths. Although not within the scope of this paper, it is also interesting that deaths due to coronary heart disease in the alcohol excess group were only half of that seen in the group with no history of alcohol excess (19.8% versus 36.1%), which would seem to support the Arriola et al. study. It may be that some of these 10 cases were indeed SUDAM cases, but at the present time, the criteria for SUDAM need to remain strictly defined until such time as it is more fully understood, allowing the boundaries to be widened. It is also likely in the authors’ opinion that in patients with preexisting cardiac disease (hypertrophic or ischaemic) that alcohol acts synergistically to potentiate fatal arrhythmia in some cases. There is just simply not enough data on this at this time from this study to answer this conclusively.

• Certain populations are predisposed to develop ketoacidosis including people with diabetes, people with a history of prolonged and heavy alcohol use, pregnant women, breastfeeding women, children, and infants.
• This is a common presentation in the emergency department (ED) and requires targeted therapies.
• The relationship between alcohol and coronary heart disease has been the subject of recent media coverage in the UK due to a study published by Arriola et al. which found that moderate, high or very high alcohol intake by men reduces their risk of coronary heart disease by more than 30% [27].
• If your doctor suspects that you’ve developed this condition, they may order additional tests to rule out other possible conditions.

After collection, the vitreous samples were immediately centrifuged at 3000 g for 15 min. The separated supernatant was collected and stored in preservative-free tubes. This drop in blood sugar causes your body to decrease the amount of insulin it produces. If they can’t use glucose because there’s not enough insulin, your body switches to another method to get energy — breaking down fat cells.

• Alcoholic ketoacidosis is the immediate cause of death in a relatively high number of cases of death of chronic alcoholics (up to 23%).
• Denmark (1993) measured the levels of beta-hydroxybutyrate in vitreous and urine in 49 forensic cases and found high concentrations in six chronic alcohol abusers with no specific immediate cause of death.
• Since all cases selected for this study originated from forensic practice with deaths occurring outside the hospital, data on antemortem biochemical results were not available.
• Based on these results and similar features in the clinical field, Denmark postulated that ketoacidosis may play a role in the multi-factorial, metabolic catastrophe leading to death in situations of alcohol withdrawal (Denmark, 1993).

• Routine clinical assays for ketonemia test for AcAc and acetone but not for β-OH.
• If not treated quickly, alcoholic ketoacidosis may be life-threatening.
• In peripheral tissues, where NADH levels are lower, this lactate may be converted to pyruvate for metabolic needs.
• Signs of shock including tachycardia and hypotension can be complicated by overlap of alcohol withdrawal [2].
• Determination of insulin, C-peptide and glucagon in postmortem serum from femoral blood was performed by radioimmunoassay (RIA) method.
• Ethyl alcohol oxidizes at a rate of 20 to 25 mg/dL per hour in most individuals.
