Q

When should fluid restriction be employed?

A

When there is hyponatremia (Na<125), should restrict fluid to 1L a day
Having ascites without hyponatremia does not require fluid restriction

Q

What weight loss per day is recommended in someone with peripheral edema and someone without?

A

Peritoneal membrane can resorb 500 cc per day. So in a patient without peripheral edema, can lose 0.5kg/day. In someone with peripheral edema, can lose 1kg/day

Q

How can you use 24 hour urinary sodium to guide therpay in ascites?

A

if Na excretion is lower than the intake –> insufficient diuresis dose

Persistent ascites despite adequate urinary sodium excretion –> dietary indiscretion

Q

How can you use the urinary Na/K ratio to help guide therapy?

A

Urine Na/K >1, patient should be losing fluid weight, and if not, dietary non compliance should be suspected

Urina Na/K <1, in suffisaient natriuresis, so need to increase diuresis

Think “diuresis should be wasting more Na than K”

Q

What is first line treatment of moderate ascites (grade 2)

A

moderate Na restriction (2g/day) + diuretics (spironolactone with or without lasix).

Of note- a study showed in first episode of ascites, spironolactone alone was effective. Those with longstanding ascites respond better to combination of lasix and aldactone

Q

What is half life of aldactone? What are alternatives to aldacone due to gynecomastia

A

three days, so shouldn’t be titrated up before 72 hours.

alternatives = amiloride or epleronone
100 mg of spironolactone = 50 mg of eplerenone or 10 mg of amiloride

Q

What is treatment of grade 3 ascites

A

grade 1 ascite = only detected by U/S
Grade 2 ascites- moderate ascites
grade 3 = marked dissension of abdomen

Grade 3 treatment = LVP. After paracentesis, Na restriction and diuretics should be started

Referral for LT should be at grade 2 or grade 3 ascites

Q

When do you give albumin after a paracentesis and how much?

A

You should give 6-8g albumin for every liter removed (but don’t need to given unless more than 5L removed)

So if remove 5L, give 40 g
if remove 8L, give 64 g

Q

What do you do for someone with positive culture but PMN<250?

Q

When do you need to do a repeat para for SBP?

A

Should be done with giving antibiotics empirically (i.e PMN>250, negative culture at 48 hours)

Should do it 2 days after intiiation of abx. Decrease in PMN <25% from baseline, means not responding and should broaden abx coverage and rule out secondary bacterial peritonitis

25
What is the goal of NE in HRS?
start at 0.5 mg/hr to achieve an increase in MAP of at least 10 mag Hg or an increase in UOP of >200 mL/4 hours. If one of these goals is not met, increase dose every 4 hours by 0.5 up to max of 3 mg/hr albumin should also be given to main a CVP fo 4 to 10 Ultimately, the response to terlipressin or NE is Cr <1.5 or within 0.3 of baseline Cr in 14 days. If Cr remains at or above pretreatment level over 4 days with max doses of vasoconstrictor tolerated, then therapy may be discontinued

What is the major cause of renal failure in cirrhosis?
Infection, followed by hypovolemia, followed by HRS those with renal failure associated with infections and HRS had the lowest 3-month survival probabilities
30
What is post paracentesis circulatory dysfunction?
activation of the renin-angiotensin system that occurs because of the removal of large amounts of ascites although clinically silent, may be associated with ascites re-accumulation, hyponatremia, HRS, and decreased surviva
31
How much albumin is given with vasoconstrictors in HRS?
Concomitant administration of albumin and vasoconstrictor drugs (1 g/kg of body weight on day 1 followed by 20–40 g/day).
32
When to use hypertonic saline in hyponatremia?
Hypertonic saline is rarely used in the stable patient without evidence of severe symptoms such as seizures due to the risk of rapid correction

TACE, due to bacterial colonization of biliary tree. unclear if this still happens but 2017 says can give moxi before and after highest risk in those with sphincterotomy

help increase muscle mass

closer monitoring. you don't change IS, you dont add mTOR, and you don't give sorafenib
48
How do you treat GAVE in cirrhosis
APC, if no improvement with APC, can do RFA> TIPS does not work because GAVE is due to vascular proliferation, not to high portal pressure
49
What types of ischemic cholangiopathy has the worse outcomes
1. Those with diffuse peripheral necrosis (highest risk of graft failure and will likely need re-transplant) 2.multifocal stenosis (intermediate risk of graft failure) 3. Strictures only at hilum, or start at hilum and then progress to intrahepatic ducts (have the best outcomes)
50
What is a risk factor for placing TIPS for refractory ascites
incarcerated hernia if umbilical hernia is present. Thought to be 2/2 to fast reduction ascites and therefore smaller defect, leading to incarceration.
51
What to do if you see gastric varices
1. see if esophageal varices are present. 2. if no EV present, and isolated gastric varices, get a CT scan to look for splenic vein thrombosis. If splenic vein thrombosis, then can be treated with splenectomy for gastric varices. 3 If actively bleeding, can try glue. and if re-bleeds, can do TIPS
52
Someone with Bili 5, INR 1.2, ALT 1000, HBV 1 million, what do you do

ALF protracted symptoms > 4weeks
54

59
Who can be placed on obeticholic acid in PBC
1. after 1 year of poor response to urso (defined as any elevation in alk phos) 2. contraindicated in patients wit: --- decompensated cirrhosis (Child-Pugh class B or C) ---a prior decompensation event (gastroesophageal varices, encephalopathy) --- compensated cirrhosis with portal hypertension(ascites, varices, thrombocytopenia) because hepatic decompensation and liver failure have been reported with obeticholic acid use in such patients can use with or without urso (if unable to tolerate urso) Response to OCA is defined as alk phos <1.67 x ULN

type 1/HFE: hepcidin deficiency type 4/FPB: reistance of binding hepcidin to ferroprotin
95
what anticoagulation levels should be replaced in cirrhosis
low fibrinogen has been associated with increased bleeding risk in cirrhosis so cryo should be used to replace >100, more so before procedures.
96
What does PVT mean in non transplant and transplant
in LT recipients, the presence of PVT at time of transplant is associated iwht increased post transplant mortality. outside of LT candidates, unknown if it correlates with mortality
97
Do you want to start AC in PVT until varices eradicated
not necessarily, can do EGD on AC. Should NOT DELAY ac until varices eradicated or beta blockade achieved
