Liver Disease Flashcards
What is chronic hepatitis?
Liver inflammation persisting >6 months
What is acute hepatits?
Acute inflammation of the liver. Can progress to fulminant hepatitis or chronic hepatitis.
What are the signs and symptoms of acute hepatitis?
- Unwell, Jaundice, RUQ pain
- Severe –> confusion (encephalopathy), bruising (coagulopathy)
Where do bloods test show in Acute Hep? (4)
Raised ALT/AST (ALT >1000), raised bilirubin, elongated coagulopathy, renal impairment
What are the symptoms of chronic hep? (3)
Often none, fatigue, possible RUQ
How does chronic hep present? (2)
Liver screening (Abnormal LFTs), cirrhosis
What is fulminant hepatitis?
- Acute hepatitis with liver failure
- The development of encephalopathy within 28 days of jaundice
- Poor prognosis - often needs transplantation
What is cirrhosis?
Fibrosis of the liver and nodular formation. initially, patient can compensate but eventually, patient decompensates leading to Loss of Function and symptoms.
What are loss of function signs? (5)
- Jaundice
- Coagulopathy
- Decreased drug metabolism - watch out benzodiazepines and opiates
- Decreased hormone metabolism - increased oestrogen (signs - spider naevi, palmar erythema, gynaecomastia, loss of secondary body hair, genitalia shrink)
- Increased sepsis risk
What are the variceal sites? (4)
oesophageal varices, rectal varices (piles), varices around umbilicus (Caput medusa), retro-peritoneal varices
What are the signs of portal hypertension? (4)
Varices, ascites, renal failure, encephalopathy
What is the treatment of portal hypertension?
Beta-blockers and shunts
How is Hepatitis A spread?
Faeco-oral
What is Hep A serology? (4)
Hep A IgM - acute infection
Hep A IgG - previous infection
HAV in stool - 1 week post-infection
ALT - acute increase with peak at weak 4
How is hep B spread? (3)
Blood (IVDU, medical), sex, vertical (mother to child)
What are serological markers of an acute Hep B infection? (2)
Anti-HBc IgM - first marker to test for as early rise. Suggests acute infection if raised.
HBsAg (surface antigen) - rises early. Disappears after 24 weeks. +ve means chronic/acute. If core IgM negative and well, then chronic
What is the serology in chronic Hep B? (3)
Persistent HbsAg (Hep B surface antigen), Anti-HBc IgG +ve
HbeAg +ve - immuno-tolerant so high viral loads –> INFECTIOUS
Anti-Hbe +ve - immunoreactive so low viral levels –> less infectious. ALT RAISED.
What is the treatment for chronic Hep B? (2)
Antiviral (entecavir/tenofovir) - life-long
Interferon - 48 week course
How is Hep C transmitted?
Blood, medical, IVDU, sex, vertical
What are tests for Hep c?
Hep C IgG antibodies - +ve means exposure
Hep C RNA -
-ve - exposed but not cleared,
+ve - chronic
How is Hep E transmitted?
Faeco-oral
What are the tests for Hep E?
IgG and IgM
What is delirium tremens?
An acute confusional state which results when someone who drinks excess alcohol daily, suddenly stops drinking. Untreated it results in seizures and even death.
