Q

What is the significance of raised ALT and AST respectively?

A

Both indicate cell damage and inflammation in the liver but ALT is liver specific. If high=serious liver damage
If ALT>AST then chronic liver disease
If AST>ALT then established cirrhosis

Q

If the patient has ascites what investigation should you do? What is a positive result suggestive of?

A

Ascitic tap to see if neutrophils are high. If they are it suggests SBP and needs prompt treatment

Q

What general steps are essential for management of cirrhosis?

A

Good nutrition, alcohol abstinence, avoid NSAIDs+sedatives+opiates, screen for HCC every 3-6 months, give colestyramine to help pruritus

17
Q

What is liver cirrhosis?

A

Irreversible liver damage with loss of normal hepatic architecture and nodular regenerations causing loss of the livers synthetic function

18
Q

What treatment when caused by HBV?

A

Avoid alcohol, immunise sexual contacts, give pegylated interferon, adefovir (reverse transcriptase inhibitor), mainly supportive in management

19
Q

What is the treatment when cirrhosis is caused by HCV?

A

Protease inhibitors (boceprevir and teleprevir) and ribavirin and pegylated interferon greatly assist virological response

Otherwise treatment is supportive

20
Q

What treatment would you give for cirrhosis due to PBC?

A

Ursodeoxycholic acid (UCDA)

21
Q

What treatment would you give for cirrhosis due to Wilson’s disease?

A

Penecillamine

22
Q

What is the treatment for ascites?

A

Low salt, restrict fluids, give spironalactone, give furosemide if poor response

23
Q

What is the treatment for SBP?

A

Cefotaxime or tazocin

Add metronidazole if necessary

24
Q

How does cirrhosis lead to deteriorating renal function?

A

Decreased clearance of immune complexes in the liver leads to build up in the kidneys causing IgA nephropathy (type of glomerulonephritis) this means IgA accumulates in the glomerulus and damages kidney function over time

25
Q

What is the overall 5 year survival?

A

50%

26
Q

Poor prognostic factors are?

A

Encephalopathy, serum Na

27
Q

Treatment for the cirrhosis itself?

A

Liver transplant is the only definitive treatment
