Viral hepatitis Flashcards
What are 3 disease-defining symptoms of viral hepatitis?
1) Tea coloured urine, yellow sclera
2) Abdo/ankle swelling
3) Hematemesis, melena
What are 3 points in a px Hx that may suggest viral hepatitis?
1) HPI:
- prodromal symptoms
- disease-defining symptoms (jaundice, portal HTN, edema)
2) Social Hx
- contact Hx
- risk factors
3) Family Hx
- of chronic viral hepatitis
What are 4 PE findings that are suggestive viral hepatitis?
1) Jaundice
2) Stigmata of chronic liver disease (eg. spider angiomas, palmar erythema)
3) Hepatomegaly
4) Splenomegaly
5) Mental state
6) Ascites/ankles edema
What are 4 complications of chronic hepatitis?
Cirrhosis:
1) Jaundice
2) Ascites
3) Ankle edema
4) Variceal hemorrhage
Liver failure:
5) Coma
6) Liver Cancer
What are 3 supportive tests for viral hepatitis?
1) Liver function test (ALT, AST)
2) Severity
- serum bilirubin
- PT
3) Chronicity
- serum bilirubin, plateley count
- US abdo
4) Others
- Plasma NH4+
- drug levels, liver auto Abs (exclude other etiologies)
What are 5 tests for etiologic confirmation of viral hepatitis?
1) Anti-HAV IgM
2) HBsAg
3) Anti-delta (total)
4) Anti-HEV IgM, IgG, HEV< RNA
5) Anti-HCV, IgG, HCV RNA
What are 4 tests to determine hepatic viral activity?
1) Anti-HBc IgM
2) HBeAg, Anti-HBe
3) HBV DNA
4) Stool HEV RNA
Which px would have a poor prognosis of acute hepatitis?
1) Progressive ↑bilirubin and PT
2) Change of mental state/asterixis
3) Elderly
4) Underlying Cirrhosis
Signs of acute fulminant liver failure/irreversible hepatic decompensation from cirrhosis → Liver transplant
What are 4 supportive treatments for acute viral hepatitis?
1) Maintain normal electrolytes and glucose levels
2) Maintain good enteral nutrition
3) Lactulose → promote bowel movement → prevent hepatic encephalopathy
4) IV Vit. K supplement
5) Ursodeoxycholic acid (2° bile acids)
How would you monitor a px progress after Rx?
1) Regular PE
2) Serial blood tests (PT, LFT, Renal function)
What are the specific treatments for HAV, HBV, HEV?
None
What are the specific treatments for HCV?
DAA (direct acting antiviral)
What are the specific treatments for chronic HBV/HDV?
1) Nucleot(s)ide analogs (oral)
- eg. entecavir, tenofovir
2) Pegylated interferon
What are the specific treatments for chronic HCV?
Direct antivirals (eg. sofosbuvir)
What are the specific treatments for chronic HEV?
Ribavirin
