Q

How does liver cirrhosis occur?

A
  • Chronic liver injury = inflammation, matrix deposition, necrosis leading to fibrosis
  • Liver injury causes necrosis and apoptosis - releasing cell contents and ROS - activation of hepatic stellate cells and tissue macrophages

Q

What is the child-push classification?

A

It is a score calculated by adding the scores of the following five factors:
- Serum bilirubin
- Serum albumin
- Prothrombin time
- Ascites
- Hepatic encephalopathy
A score of under 7 is good and more than 10 is bad

Q

What would the liver biochemistry show in someone with liver cirrhosis?

A
  • Most cases there would be raised AST and ALT
17
Q

What would a low Na+ indicate?

A

Severe liver disease

18
Q

What would you see on imaging techniques in liver cirrhosis?

A

Ultrasound

  • Shows change in the size and shape of liver - hepatomegaly
  • May be marginal modularity of the liver surface and distortion of the arterial vascular architecture
19
Q

What would a CT scan show in liver cirrhosis?

A
  • Hepatosplenomegaly

- Hepatocellular carcinoma

20
Q

What would an endoscopy show in liver cirrhosis?

A

Detection of varies and portal hypertension gastropathy

21
Q

Complications: what would coagulopathy be due to?

A

A fall in clotting factors produced in the liver

22
Q

Complications: what is hepatic encephalopathy a result of?

A

Ammonia is not broken down in the liver and so travels to the brain

  • Asterixes
  • Confusion/coma
23
Q

Complications: why would you get hypoalbuminaemia and what would it result in?

A

The liver isn’t producing albumin resulting in oedema

24
Q

Complications: Why would you get portal hypertension?

A
  • Ascites
  • Oesophageal varices
  • Caput medusa
25
Q

What is the treatment for liver cirrhosis?

A
  • Fluid restriction for ascites
  • Alcohol abstinence
  • Hep A and B vaccination
  • Reduce salt
26
Q

If the cirrhosis is very advanced what is the management option?

A

Liver transplant
