16
Q

Test for autoimmune hepatitis

A

ANA or

Anti smooth muscle antibody (ASMA)

17
Q

Major causes of chronic cholestatic syndromes

A

Primary biliary cirrhosis
Autoimmune cholangitis
Primary sclerosing cholangitis
Idiopathic adulthood ductopenia

18
Q

Characterized by portal inflammation and necrosis of cholangiocytes in small and medium sized bile ducts

A

Primary biliary cirrhosis

19
Q

Treatment of choice for decompensated cirrhosis from PBC

A

Liver transplantation

20
Q

Is the only approved treatment for PBV by slowing the rate of progression of the disease

A

UDCA

21
Q

Antibodies present in 90% of PBC

A

Antimitochondrial antibodies (AMA)

22
Q

4 stages of Primary Biliary cirrhosis

A
  1. Chronic nonsuppurative destructive cholangitis
  2. Involving peri portal areas
  3. Bridging fibrosis
  4. Cirrhosis
23
Q

Seen in approx 50% of patients with PBC

A

Pruritus

24
Q

True or false. Pruritus that presents prior to development of jaundice indicated milder disease

A

False. Severe disease and poor prognosis

25
Q

Dosage of UDCA in PBC

A

13-15 mg/kg/day

26
Q

How is pruritus treated in patients with PBC

A

Antihistamines
Narcotic receptor antagonist (naltrexone)
Rifampicin
Cholestyramine

27
Q

Chronic cholestatic syndrome characterized by diffuse inflammation and fibrosis involving the entire biliary tree resulting in chronic cholestasis

A

Primary sclerosing cholangitis

28
Q

What is concurrent in patient with PSC and what investigations should be done

A

PSC will have overlap with AIHA

50% of patients with PSC will have uclerative colitis thus Colonoscopy is peformed

29
Q

What is the typical cholangiographic findings in PSC

A

Multifocal sticturing and beading involving the intrahepatic and extra hepatic biliary tree. Strictures are typically short and with intervening segments of normal or slightly dilated bile ducts

30
Q

Dreaded complication of PSC

A

Cholangiocarcinoma

31
Q

What is the pathology of cardiac cirrhosis

A

Elevated venous pressure transmitted via the Inferior vena cava and hepatic veins to the sinusoids of the liver which became dilated and engorged with blood. Liver becomes enlarged and swollen

32
Q

True or false. Patient with cardiac cirrhosis will also have chances of developing variceal hemorrhage and encephalopathy

A

False. It is unlikely patient will develop variceal hemorrhage or encephalopathy

33
Q

Difference between cardiac hepatopathy and Budd Chiari Syndrome

A

In Budd Chiari Syndrome there is extravasation of RBC

34
Q

Inherited disorder of iron metabolism that results in progressive increase in hepatic iron deposition which over time can lead to portal based fibrosis progressing to cirrhosis

A

Hemochromatosis

35
Q

Major complication of cirrhosis

A
  1. Portal hypertension
  2. Gastroesoohageal variceal hemorrhage
  3. Splenomegaly
  4. Ascites
  5. Hepatic Encephalopathy
  6. SBP
  7. Hepatorenal syndrome
  8. HCC
36
Q

Definition of portal hypertension

A

Elevation of hepatic venous pressure gradient to (HVPG) to more than 5 mmHg

37
Q

What is the pathophysiology of portal hypertension

A
  1. Increased intrahepatic resistance to passage of blood

2. Increased splanchnic blood flow secondary to vasodilation within splanchnic vascular bed

38
Q

Complications directly related to portal hypertension

A
  1. Variceal hemorrhage

2. Ascites

39
Q

Immediate life threatening problem in portal hypertension with a 20-30% Mortality rate

A

Variceal hemorrhage
