GI Flashcards
give some symptoms of acute liver failure
nausea malaise anorexia hepatomegaly jaundice, confusion, bleeding and hypoglycaemia are rare
what are some symptoms specific to chronic liver failure?
ascites
clotting disorder
jaundice
pruritis
spider naevus
endocrine problems (gynaecomastia/impotence/amenorrhoea)
fluid overload (due to systemic vasodilation)
signs: hepatic flap, Dupuytren’s contracture, disorentation, oedema, clubbing, palmar erythema
what hepatitis viruses can cause chronic liver disease?
B (D) and C
what is cholangitis and how does it present?
infection of the biliary tree, caused by bile duct stones. It presents with RUQ pain, fever and jaundice. It can lead to pancreatitis.
what is cholecystitis
inflammation of the gallbladder caused by gallbladder stones, patients usually have a history of biliary colic and palpable gallbladder, jaundice is unlikely. Think CYST, fluid filled sac so it’s the gallbladder rather than the biliary tree.
why are liver disease patients likely to get infections?
impaired reticuloendothelial system
give some signs that a liver failure patient may be deteriorating
hyponatraemia constipation infection spontaneous bacterial peritonitis kidney failure
what 3 things lead to ascites?
fluid retention
low albumin levels
portal hypertension
list some causes of hepatic encephalopathy
hypokalaemia GI bleed infection sedatives analgesics constipation
what do you give a patient with hepatic encephalopathy
lactulose, it decreases ammonia absorption from the gut
what is paracentesis
taking fluid from the abdominal cavity, may sample it to see if they have bacterial peritonitis (culture and ^WCC)
what is fulimant hepatic failure?
when decompensation starts within 12 weeks of onset of disease, the liver can’t regenerate or repair
what decreases risk of bleeding from varicies
beta blockers, if bleeding need endoscopy and somatostatin
why do you test INR rather than LFTs to test liver function?
patients with chronic liver disease may have normal LFTs. INR=prothrombin time
signs that suggest decompensation
coagulopathy
jaundice
ascites
encephalopathy
which hepatitis viruses are blood borne?
B, D and C. A and E are faeco-oral
how is hepatitis C infection treated?
it is usually chronic, can be cured with antivirals, protease inhibitors and pegylated IFN
which hepatitis viruses have a vaccine?
A, B, E
what are AST and ALT?
serum aspartate=AST
alanine aminotransferases=ALT
if increased, they suggest hepatocellular damage
what will be elevated in primary biliary cholangitis?
anti-mitochondrial antibody
anti-nuclear cytoplasmic antibody
IgM
apart from liver disease, what may cause hypoalbuminaemia?
malnutrition
urinary protein loss
sepsis
what is ALP?
alkaline phosphatase, it is in liver membranes, bone, intestine, placenta. Raised in intrahepatic and extra hepatic cholestatic disease, cirrhosis and liver metastases
what on the hands indicates chronic liver disease?
palmar erythema, Dupuytren’s contracture is more a sign of alcohol consumption
what is NASH
non alcoholic steatohepatitis, a type of non alcoholic fatty liver disease, it can complicate to cirrhosis
