Q

How to tell between A and E on serology?

A

Q

What is seen in hep B serology?

A

Surface antigen and core antigen on hep B!

In response we produce surface antibody and core antibody. We vaccinate to produce the surface antibody.

Surface antibody - vaccinated or previous infection
Core antibody - actually has infection
If they have HBsAg (the actual hep b antigen) then it’s happening rn needs these below to differ:

IgM - acute
IgG - longer term

Surface - Anti-HBs
Core - Anti-HBc

17
Q

What happens in liver cirrhosis?

A

Normal liver replaced with fibrosis ad nodules of regenerating hepatocytes.

Alc misuse, viral hep, autoimmune, haemochromatosis etc.

18
Q

Signs of chronic liver disease/cirrhosis?

A
Clubbing
Spider naevi (at least 3)
Palmar erythema
Gynaecomastia
Bruising
Dupytren's contracture
19
Q

What is portal hypertension?

A

Liver is cirrhotic so increased pressure in portal vein.
Blood flows from portal to systemic circulation.
Can cause - distended veins (varices), ascites, splenomegaly, caput medusae

20
Q

How to manage cirrhosis?

A

Treat cause and avoid hepatotoxic drugs e.g. NSAIDs

Monitor risk of complications (SBP (infection of ascites), encephalopathy, ascites

21
Q

How to manage complications of cirrhosis?

A

Encephalopathy - protein restriction, oral lactulose, oral rifaximin, phosphate enema but avoid sedatives
Ascites - sodium restriction, diuretics, paracentesis
SPB (>250 neutrophils) - Abx (cefotaxime)
Varices - monitor needs own page

22
Q

How to treat varices?

A

Prophylaxis - beta blocker
Rupture - ABCDE, fluids, bloods, terlipressin and Abx, ligation
Secondary prophylaxis - beta blocker

TIPS procedure

23
Q

What is cholelithiasis?

A

Gallstone in gallbladder (no jaundice)

24
Q

What is biliary colic?

A

Gallstones in bladder or CBD causing pain (no jaundice)

25
Q

What is acute cholecystitis?

A

Gallstone in gallbladder causing inflammation - can be secondary to an infection (no jaundice unless meritzis)

26
Q

How do we treat cholelithiasis, biliary colic and acute cholecysitits?

A

1 - incidental no Mx
2 - analgesia and elective lap chole
3 - clear fluids, analgesic, fluid resus with IV abx with elective lap chole

27
Q

What is choledocholithiasis?

A

Gallstone in CBD (jaundice)

28
Q

What is ascending cholangitis?

A

Infection of the biliary tree (jaundice)

29
Q

When would we do ERCP?

A

Biliary colic if in CBD
Choledocholithiasis (with analgesia
Ascending cholangitis

30
Q

What is charcot’s triad?

A

RUQ pain
Jaundice
Fever

Signs of asce cholangitis
