Q

What is alcohol dehydrogenase?

A
  1. hepatic enzyme that converts alcohol to acetaldehyde

16
Q

What does Alcohol dehydrogenase and acetaldehyde dehydrogenase do?

A

reduce nicotinamide adenine dinucleotide (NAD) to NADH (reduced form of NAD)

17
Q

What does the excessive NADH in related to NAD inhibit?

A

inhibits gluconeogenesis and increases fatty acid oxidation, which in turn promotes fatty infiltration in the liver (steatosis)

18
Q

How else is alcohol damage caused?

A
  1. Oxygen free radical production through CYPP-450 2E1

2. Hepatocyte TNF-a production induces oxygen free radical production

19
Q

What would FBC show in alcoholic hep?

A

macrocytic anaemia

20
Q

What would LFTs show in alcoholic hep?

A
  1. AST/ALT ratio >2
  2. HIGH bilirubin
  3. -/↑ALP
  4. HIGH GGT
  5. LOW albumin
21
Q

What would clotting screen show for alcoholic hep?

A

INCREASED prothrombin time sensitive marker of significant liver damage

22
Q

What imaging can be done for alcoholic hep?

A

hepatic USS

23
Q

Why is hepatic USS performed?

A
  1. performed in cirrhotic patients to screen for hepatocellular carcinoma but is not the first line investigation (LFTs are)
  2. USS may also show hepatomegaly, fatty liver, liver cirrhosis, liver mass, splenomegaly, ascites, evidence of portal hypertension
24
Q

What is the diagnostic, but rarely needed test for alcoholic hep?

A

liver biopsy

25
Q

What does liver biopsy show in alcoholic hep?

A

Balloning and Mallory bodies indicates hepatitis - which are damaged intermediate filaments inside hepatocytes

26
Q

What do you give in severe alcoholic hep?

A

steroids

27
Q

What is the management for alcoholic hep?

A
  • Alcohol abstinence + withdrawal management (chlordiazepoxide)
  • Nutrition (thiamine- pabrinex, prevent Wernicke-Korsakoff)
  • Weight loss/stop smoking
  • Steroids in severe alcoholic hepatitis
