Case 3: Cirrhosis Flashcards
Diagnoses:
-Pruritis -COPD -Alcohol abuse -Tobacco abuse -Cirrhosis -Hepatitis C infection -Anemia -CKD 3b
Pruritis: Etiology -Can develop in patients who have ________ due to any cause -List Ex’s
**cholestasis -Intrahepatic cholestasis of pregnancy -Primary sclerosing cholangitis -Malignant biliary tract obstruction -Chronic viral hepatitis -Nonmalignant biliary tract obstruction -Cirrhosis
Pruritis: Pathology -elevated levels of ____ acids in the skin act as pruritogens -Pruritis is also associated with higher serum ____ levels and autotaxin activity
-Incompletely understood -**Elevated levels of bile acids in the skin can act as pruritogens -Lysophosphatidic acid and autotaxin–>Phospholipid formed by action of autotaxin –Studies show patients with cholestatic pruritis had much higher serum LPA levels and autotaxin activity –Injection of LPA induced scratch responses in mice
Pruritis: Pathology: _______ ______ levels are elvated in Patients with chronic liver disease
Endogenous opioid
Cholestatic Pruritis: tx -The following treatments can be used if the Pt doesn’t have which 2 conditions: -1st line tx ? -2nd line ? -3rd line ?
-If the Pt doesn’t have intrahepatic cholestasis of pregnancy or primary biliary cholangitis: Bile acid sequestrant 1st line (Ie: **cholestyramine (Questran) or colestipol (Colestid) –80-85% of patients respond 2nd: Try rifampin (Rifampicin) 3rd: opioid antagonist Ie: naltrexone (Vivitrol) If above fails, try sertraline or phenobarbital
MELD Score=
Model for End-Stage Liver Disease
What labs are included in MELD score calculation?
Uses serum bilirubin, creatinine, INR, and whether a patient has recently had dialysis to predict 3-month survival -2016: Serum sodium added (MELDNa score)
Higher MELD score indicates ______
worse liver dysfunction and ↑ mortality risk
MELD score is used to prioritize Pts awaiting ____
liver transplant
Cirrhosis: complications?
-Variceal hemorrhage -Ascites -Spontaneous Bacterial Peritonitis -Hepatic encephalopathy -hepatic hydrothorax -Hepatocellular Carcinoma -hepatopulmonary Syndrome
Variceal Hemorrhage: management?
-EGD screening/band ligation -Nonselective beta blocker (propranolol, nadolol)
Ascites: tx?
-Diuretics: Spironolactone/furosemide (100:40 ratio) -+/- Paracentesis (albumin replacement after large volume paracenteses if > 4-5 L are removed) -Sodium restriction
