Module 3 Chapter 14: Cirrhosis Flashcards
Lab diagnosis for cirrosis
AST>ALP, increased ALP, decreased platelets, increased bilirubin, increased INR, decreased albumin.
imaging diagnosis for cirrhosis
nodular liver or evidence of portal hypertension and big spleen.
physical exam diagnosis for cirrhosis
hyper dynamic circulation (decreased BP and increased HR), stigmata of chronic liver disease (jaundice, ascites, edema, estrogen issues, encephalopathy)
what is mainly responsible for the development of complications? (decompensation)
portal hypertension
the child Pugh score is scored ___(5-6), ____ (7-9) or C (10-15). What components does it comprise of?
encephalopathy ascities bilirubin albumin INR
MELD Score
developed to predict survival after trans jugular portosystemic shunt insertion (TIPS).
Includes bilirubin, INR, creatinine.
Used for liver transplant, but now it includes sodium.
pathophysiology behind varies
o Varices form in response to portal hypertension and represent the reopening of connections
between the portal and systemic circulation
o They are most commonly seen in the distal esophagus, stomach and rectum
clinical presentation of varices
- hematemesis
- melena
- hematoochezia
when should screening for varices occur?
cirrhotics should undergo surveillance endoscopy to look for varices.
but they don’t need an endoscopy if platelets are above 150.
preventing the first bleeding of esophageal varices
NSBB (nadolol, propanolol) or Banding
BUT: Beta blockers do not prevent the varices from FORMING. they prevent existing varices from BLEEDING.
endoscopy and banding should be done every 2-4 weeks until varices are obliterated.
during an active esophageal variceal bleed, what should be given?
- volume expansion (saline) and RBCs if Hb is low.
- 7 days of antibiotics
- octreotide bolus plus infusion 3-5 days
- EGD for banding.
- TIPS for uncontrolled or recurrent bleed.
when should TIPS be considered in cirrhotic patients?
when variceal bleeding is uncontrolled or recurrent
classification of gastric varices
GOV1 along the lesser curvature
GOV2: along greater curvature
Isolated gastric varices
IGV1= in the fundus
IGV2= else where in the stomach.
primary prophylaxis of gastric varices
injection of glue– superior to NSBB in preventing the first bleed.
what to do during gastric variceal bleeding
gluing is preferred, as banding in the stomach is difficult.
gastric varices secondary prophylaxis
NSBB and gluing or consider TIPS for recurrent bleeding
portal hypertensive gastropathy
mosaic pattern in the stomach due to congestion (“snake-skin boot” appearance) and
may have erythema or red spots
gastric antra vascular ectasia
red streaks in the antrum (“watermelon stomach”), or a more diffuse
pattern similar to PHG, and is seen with cirrhosis and connective tissue diseases
management of Portal hypertensive gastropathy
NSBB, octreotide for acute bleeding, TIPS or liver transplant for refractory bleeding
management for Gastric antra vascular ectasia
argon plasma coagulation (APC) or Nd:YAG laser, estrogen therapy, banding might be helpful in antrum, surgery (if not cirrhotic)
pathophysiology of ascites in cirrhosis
Cirrhosis leads to portal hypertension → vasodilators (nitric oxide, carbon monoxide) are produced in response to high pressure in liver and portal circulation → vasodilators get into systemic circulation via collaterals → leads to vasodilation in the systemic circulation (hyperdynamic circulation with ↓ BP and ↑ HR) → kidneys respond to this with activation of renin-angiotensin-aldosterone system (RAAS) → sodium and water retention → worsen portal hypertension → ascites eventually is forced through the liver capsule and peritoneal lining into abdominal cavity NOTE: patients often have cirrhotic cardiomyopathy and low albumin, which contribute to ascites formation
what must be tested when someone presents with ascites?
spontaneous bacterial peritonitis has a mortality of 20% and can lead to hepatic renal syndrome (must do paracentesis to confirm). SBP may be present with fever and high WBC and high creatinine
What must you do with albumin count when someone has ascites?
CALCULATE SEUM ASCITES ALBUMIN GRADIENT= (albumin in serum) - (albumin in the ascites fluid)
if ascites is due to Budd chiari syndrome, the protein is ____ and they are at ___ risk for SBP
high protein, low risk for SBP.
a diagnosis of SBP would have a high ____ count
high neutrophil count. The culture and sensitivity would also be spiked.
first line treatment for asictes
sodium restricted diet - stop alcohol - stop NSAIDS - diuretics (spironolactone) consider for liver transplant
second line treatment for refractory asciets
- large volume paracentesis
- consider stopping NSMM, ACE inhibitors because these can LOWER BP and thus WORSEN fluid retention. - Add MIDODRINE to increase BP and facilitate renal perfusion.
- TIPSS (shunt), lowers portal pressure but improves renal perfusion.q
when should you NOT do tips
when there’s hepatic encephalopathy. you can worsen neurological symptoms further if you have a shunt
treatment for Spontaneous bacterial peritonitis
antibiotics
intravenous albumin
definition of hepatorenal syndrom
- cirrhosis with ascites
- high serum creatinine
-no shock
can manifest via SBP
type II vs type I HRS
o Type II = slow increase in creatinine in
patients with refractory ascites undergoing frequent LVP, which often responds to lowering diuretics
o Type I = rapid deterioration in renal
function, often precipitated by infection or
NSAIDs
Treatment for HRS
midodrine to increase BP (also used as a second line ascites treatment)
- octreotide to lower portal pressure
- albumin intravenously to improve circulation.
consider TIPS. Prognosis is very poor, HRS is an indication for liver transplant.
hepatic encephalopathy
Hepatic encephalopathy (HE) is a brain dysfunction caused by liver insufficiency and/or portosystemic shunting which manifests as a wide spectrum of neurological or psychiatric abnormalities ranging from subclinical alterations to coma
Type A, B and C causes of hepatic encephalopathy
o Type (underlying disease) A = Acute Liver Failure B = Portosystemic shunt C = Cirrhosis
treatment of hepatic encephalopathy
- lactulose (remember that this doesn’t help with acute liver failure, but will help with HE via cirrhosis). It is converted to lactic acid in colon creating acidic environment which slows NH3
absorption - antibiotics
- BCAAs, liver transplantation if refractory
T/F: should restrict protein on cirrhotic patient
false.
condition where ascites travels through the diaphragm
hepatic hydrothorax. can be complicated by infection/sbp. treat just like ascites
- reduce salt intake
- no alcohol
- dieuretics
- stop NSAIDs
2nd:
- paracentesis
- midodrine
- consider TIPSS
- consider stopping ACE inhibitors.
T/F can use acetaminophen if cirrhotic
true, as long as they are not using alcohol. should avoid basis as they can cause Gi bleeding and HRS. Opioits can also accumulate and precipitate hepatic encephalopathy
