31
Describe the pathophysiology of alcoholic ketoacidosis?
* Lipolysis tends to increase because of increased levels of cortisol and catecholamines, causes by extra stress placed on body by alcohol
* Lipolysis contributes to abundance of FFA, which in turn sees diverted ketone production
* Usually the ketone beta-hydroxybutyrate
* Excess alcohol metabolised drives NADH+ production, which drives production of ketone beta-hydroxybutyrate
* Chronic alcohol misusers have depleted reserve, ethanol will provide calorie intake though glycogen stores depleted
* Metabolism of ethanol raises NADH/NAD which impairs hepatic gluconeogenesis and the metabolism of lactate
* So patient has impaired ability to make glucose, or metabolise lactate driving the hypoglycaemia and acidosis
32
What ketone is usually seen in alcoholic ketoacidosis?
* Usually the ketone beta-hydroxybutyrate
33
What is done to stailise a patient with alcoholic ketoacidosis?
To stabilise patient:
* IV fluids

34
What is vitamin B1?
Thiamine
35
Why is thiamine so important for metabolism?
Thiamine is used at multiple points as co-factor
