Cirrhosis Flashcards
Cirrhosis defined
Diffuse bridging fibrosis and nodular regeneration via Stella the cells that disrupt normal architecture
Causes of cirrhosis
Alcohol (60%), chronic viral hepatitis, biliary disease, genetic/metabolic disorders
Effects of portal hypertension
Esophageal varices (hematemesis) peptic ulcer (melena) Splenomegaly Caput medusae, ascites Gastropathy Anorectal varices
Effects of liver cells failing
Hepatic encephalopathy Sclera icterus Fetor hepaticus (musty breath) Spider nevi, Gyneocmastia, testicular atrophy (dt inc estrogen) Jaundice Asterixis (hand tremor) Bleeding (dec clotting factors) inc PT Ankle edema Anemia
Serum marker: alkaline phosphatase (ALP)
For cholestatic and obstructive hepatobiliary disease,
HCC
Infiltrative disorders
Bone disease
Aminotransferases (AST and ALT) is for measuring
Liver enzymes Viral hepatitis (ALT >AST) Alcoholic hepatitis (AST > ALT)
Amylase is for measuring
Acute pancreatitis
Mumps
Ceruloplasmin is for diagnosing
Wilsons disease (it will be low)
Y-glutamic transpeptidase (GGT) is for measuring
Increases in various liver and biliary diseases but not in bone disease
Associated with alcohol use
Lipase is most specific for measuring
Acute pancreatitis
Non-alcoholic fatty liver disease
Metabolic syndrome due to insulin resistance
Fatty infiltration of hepatocytes
Cellular ballooning and eventual necrosis
May cause cirrhosis and HCC
High ALT
Hepatic encephalopathy cause
Cirrhosis, then portosystemic shunts, decrease in NH3 metabolism , then neuropsych dysfunction
High NH3 levels
Hepatic encephalopathy presentation
Disorientation/ asterixis (mild) to difficult arousal or coma
Increased NH3 production and absorption is from
Dietary protein, GI bleed, constipation, infection
Decreased NH3 removal is due to
Renal failure, diuretics, bypassed hepatic blood flow post-TIPS
Hepatic encephalopathy treatment
Lactulose to increase NH4 generation and
Rifaximin
Diagnosis of HCC is always preceded by either
HBV or cirrhosis
Portal HTN leads to
Thrombocytopenia (dt splenic sequestration)
Ascites
Encephalopathy
Varices
For the diagnosis of spontaneous bacterial peritonitis one must have….
> 250 polys
Treatment for ascites
Furosemide
Spironolactone
Therapeutic paracentesis
Fluid restricted diet (low salt and water)
Portal hypertension intially leads to increased ____________, ____-_____ _________ and _________
Resistance
Porto-systemic collaterals
Splenomegaly
Most common causes of cirrhosis
Alcohol HCV NASH Autoimmune hepatitis HBV PBC PSC Hemochromatosis
Decompensation physiology that leads to it
Portal HRN
Hyperdynamic circulation
Liver insufficiency
Physical exam findings in compensated cirrhosis
Bitempotal muscle wasting Spider nevi Palmar erythema Palpable left lobe of liver Small liver span right lobe Splenomegaly
(No ascites or encephalopathy)
