Q

If you see an alcoholic with a visible vein on the abdominal wall, which other finding are you most likely to see:

A: hepatomegaly, B: splenomegaly, C: bilateral palpable kidneys, D: palpable bladder, E: enlarged prostate on PR

A

B: splenomegaly

EtOH –> nodules form –> cirrhosis. this cause portal Hypertension.

This blood backs up into the splenic vein –> splenomegaly

Q

Life cycle of the hepatocyte - how does it move over time?

A

Hepatocytes are ‘born’ in zone 1, closest to the portal triad,

The move towards zone 3 as they mature

  1. Whole liver involvement
  2. Fibrosis
  3. Nodules of regenerating hepatocytes

Q

what is ‘piecemeal necrosis’

A

Interface hepatitis i.e. inflammation is at the area between lobules + portal triad, resulting in loss of limiting plate between portal triad/hepatocytes

Q

Wilson’s disease - what is the pathophysiology?

A

Mutation of copper ATPase gene (Chr13) leading to copper overload due to failure of secretion in bile

Q

what is the responsible antibody in autoimmune hepatitis?

A

Anti-smooth muscle

24
Q

the effect of a1-antitrypsin deficiency on the liver?

A

the enzyme is synthesised but cant be secreted

  • TONS of enzymes in hepatocytes, but NONE in blood
  • Intracytoplasmic inclusions –> fibrosis + cirrhosis
25
Useful lab investigation of suspected hepatocellular carcinoma
alpha-fetoprotein
26
Anti-mitochondrial antibodies
PBC - primary biliary cirrhosis
27
Anti-smooth muscle antibodies
autoimmune hepatitis
28
Perl's prussian blue stain
Stains for iron in the liver
29
haemochromatosis vs haemosiderosis causes
Haemochromatosis is genetic Haemosiderosis is due to acquired cause (transfusions, EtOH)
30
List cells of the liver
Hepatocytes Bile ducts BVs Endothelial cells Kuppfer cells - macrophages Stellate cells - Vit A store / activated to myofibroblasts
31
What is the portal triad
portal vein artery and bile duct
32
Which liver zone is the most mitotically active?
zone 3 closest to portal triad
33
Describe stellate cell activation
Reduced hepatocyte microvilli Deposition of scar matrix Collagen deposition in space of Dyss, reducing blood flow to hepatocytes Loss of fenestrate between endothelial cells Kuppfer cells activated
34
What is the point of stellate cell activation?
Causes cirrhosis
35
complications of cirrhosis
portal HTN eg varices hepatic encephaopathy - increased toxicity of blood due to reduced filtering liver cell cancer
36
is cirrhosis reversible?
Can be in viral hepatitis if treated aggressively ith antivirals
37
causes of acute hepatitis
Viruses - A and E drugs
38
histology of acute hepatitis
spotty necrosis
39
causes of chronic hepatitis
viruses - B,C,D drugs AI
40
what do grade and stage mean in cirrhosis?
grade = severity of inflamm stage = severity of cirrhosis
41
cause of NAFLD
insulin resistance associated with high BMI or DM
42
Histology of PBC
bile duct loss, chronic inflammation and granulomas
43
who gets PBC
Middle aged females
44
complication of PBC
50% cirrhosis
45
histology of PSC
dense fibrosis - onion skinning - around bile duct, leading to bile duct loss
46
what cancer are PSC patients at risk of getting?
Cholangiocarcinoma
47
where is the iron accumulation in haemochromotosis
INTRAcellular - hepatocytes also in pancreas / skin --> "bronzed diabetes"
48
what conditions is alpha 1 antitrypsin deficiency associated with?
Emphysema, hepatitis and cirrhosis
49
Specific and general causes of hepatic granulomas
Specific = PBC, drugs General = TB, sarcoid
50
What is a granuloma?
Giant cell with activated macrophages around
51
Which liver cancers are benign?
Liver / bile duct adenoma Haemangioma
52
Which liver cancers are malignant?
Secondary mets Hepatocellular Hepatoblastoma Cholangiocarcinoma Haemgiosarcoma
53
Who gets hepatocellular carcinoma?
Old, Western men with cirrhosis
54
Who gets hepatoblastoma?
Kids
55
Associations of cholangiocarcinoma?
PSC, worms, cirrhosis
56
Multiple lesions seen throughout liver. What type of cancer? Why?
Mets - portal circulation comes from many organs and passes through liver so easy route of transmission
