Q

what is the main mechanism of NASH?

A

triglyceride infiltration–> hepatocellular injury may be related to free oxygen radical formation and induction of cytochrome p-450 for metabolism of FFA

Q

What is a major complication of SBP?

A

hepatorenal syndrome

25
What are the indications of paracentisis?
New onset ascites, signs of SBP, clinical deterioration, symptom relief
26
Is coagulopathy a contraindication of paracentisis?
No
27
What are the causes of SAAG >1.1?
portal hypertension from cirrhosis, SBP, acute hepatits, RHF, venous thrombosis, schisto TRANSUDATE
28
What are the causes of SAAG
peritoneal carcinomatosis, pancreatitis, peritoneal dialysis EXUDATE
29
If ascites prtoein is
SBP prophylaxis
30
if PMNs >250 what do we know?
SBP diagnosis | also can do gram stain + culture
31
What should be the treatment for SBP
Cefotaxime- ceftriaxone | albumin infusion to minimize risk of hepatorenal syndrome
32
What are the indications for SBP prophylaxis?
hospitalized cirrhotics w/GI bleed ascites protein 2.5 prior SBP
33
what is hepatorenal syndrome>
AKI- vasodilation of splanchnic arteries and vasoconstriction of renal circulation
34
How doe we diagnoses hepatorrenal syndrome
AKI no response to colume challenge diagnosis of exclusion- must do full AKI work-up
35
What is the treatment of hepatorenal syndrome
increase MAP by 10-15 ICU- norepinephrine + albumin Not ICU- octeotride + midodrine (a1 agonist)+ albumin
36
What is the treatment for Hepatitis B?
supportive for acute infections | IFN-a-2b or lamivudine for chronic
37
Hepatitis C treatment?
old= ribavirin IFN | New- simepravir, sofosbuvir+ledipasvir, ombitasvir/paritaprevir/ritonavir
38
What is the most common cause of chronic hepatitis?
Hepatitis C
39
does Hep B or C have a more acute presentation?
Hep B, but only becomes chronic in 20%
40
what is the mechanism of fibrosis in cirrhosis?
mediated by TGF-B secreted by stellate cells
41
What are the 6 clinical features of cirrhosis
``` portal HTN Increased ammonia Increased estrogen jaundice hypoalbuminemia coagulopathy ```
42
viral hepatitis, autoimmune hepatitis, hemachromatosis cause what pattern of hepatic damage?
periportal
43
alcoholic hepatitis, NASH, CHF, bud chiari cause waht pattern of hepatic damage?
central vein
44
In NASH is ALT or AST higher?
ALT>AST
45
What is different about the biopsy in NASH from ALD?
greater fatty change than alcoholic type
46
What are the iron labs for hemochromatosis?
up ferritin down TIBC Up serum Fe Up % saturation
47
What distinguishes hemochromatosis from normal lipofuscin?
prussian blue stain
48
what is the treatment for hemochromatosis?
phlebotomy
49
What is the treatment for wilson's disease?
D penicillamine
50
What has granulomatous destruction of intrahepatic bile ducts only?
PBC- florid duct lesions | antimitochondrial antibody
51
PSC intra or extrahepatic?
both
52
does PBC increase risk of cholagiocarcinoma?
No
53
What are risk factors for HCC?
chronic hepatitis cirrhosis aflatoxins derived from aspergillus- induce p53 mutations
54
What is an HCC patient at huge risk for>
Budd chiari syndrome | -->invasion of hepatic vein-->thrombosis-->infarction
55
what does anti-HBe mean?
low infectivity
56
What does anti-HBS indicate?
immunity (if it also has anti-HBe IgG, or antiHbc IgG) it means recovery vs. immunized
57
What does antiHBc IgG mean?
chronic or prior exposure
58
true or false- GGT is decreased in Alcoholic liver disease?
false elevated
59
What is the difference between type A and B of drug induced hepatitis?
type A- dose dependent toxicity like tylenol and INH. | type B- unpredictable- occurs at therapeutic doses- nitrofurantoin
