How is chronic viral hepatitis B managed?

Describe the LFTs of someone with NASH as opposed to alcoholic liver disease
AST:ALT ratio <1 in NASH whereas in ALD AST:ALT > 2:1
How is NASH progression to cirrhosis measured?
Hepatic US
Recall the pathophysiology of alcoholic liver disease
Alcohol metabolism –> Excess NADH –> inhibition of gluconeogenesis and FA oxidation
What % of heavy drinkers will develop alcoholic hepatitis?
10-15%
What electrolyte imbalance results from ascites?
Hyponatraemia
What 3 tests would you do first-line in suspected Wilson’s disease?

Recall 3 symptoms of haemachromatosis
Tanned skin
T1DM
Liver symptoms
What is Boas’ sign?
Radiation of cholecystitis pain to scapula
Differentiate the expected LFTs in cholelithiasis vs choledocholithiasis
Cholelithiasis: normal
Choledocholithiasis: raised ALP
Differentiate cholelithiasis and choledocholithiasis
Cholelithiasis = in gallbladder Choledocholothiasis = in CBD
Describe the ERCP procedure
Endoscope down into small bowel to the opening of the bile duct
Differentiate ascending cholangitis and acute cholecystitis
Ascending cholangitis is caused by stasis in the CBD, whereas acute cholecystitis is to do with inflammation in the gallbladder or cystic duct
Charcot’s triad and Reynold’s pentad are associated with which condition?
Ascending cholangitis
If RUQ pain is constant, what sort of infection is it most likely to be?
Acute cholecystitis
Rebound tenderness is indicative of which pathology in the RUQ?
Acute cholecystitis
Is jaundice more likely to develop in acute cholecystitis or ascending cholangitis?
Ascending cholangitis
What is a common comorbidity of PBC?
Sjorgen’s syndrome
Which antibodies are diagnostic of PBC?
AMA
What is the diagnostic test for PSC?
MRCP
What is seen upon MRCP in PSC?
Beading
Which test is diagnostic of gallstones?
USS biliary tree
