HEV
what hepatitis viruses have a vaccine available?
A and B
what hepatitis viruses are spread fecal-orally?
A and E
what serology is used to diagnose Hep A?
IgM
what serology is used to diagnose Hep B?
HBsAg
HBcAg
PCR
what serology is used to diagnose Hep C?
HCAb
PCR
what serology is used to diagnose Hep D?
HDV IgM
PCR
what serology is used to diagnose Hep E?
HEV PCR, IgM
which hepatitis viruses cause acute infection?
A and E
AcutE
what will be the biggest clinical distinguishing factor between Hepatitis A and E?
exposure risk
A: daycares
E: travel, unclean water, shellfish, etc.
elevated liver transaminases into the 1000s indicates
Hep A/E
fulminant hepatic failure occurs in 20% of pregnancy cases
Hep E
whats a good way to differentiate the acute hepatic viruses causing hepatitis from CMV, EBV, etc.?
its a lab value
CMV/EBV usually only cause liver transaminases to rise into the 100s and usually have associated pharyngitis
HepA/E would cause AST/ALT into the 1000s
first stage of liver scarring after portal tract inflammation
fibrosis
HCV induces insulin resistance leading to […] which contributes to fibrosis
steatosis
when fibrosis takes over the whole liver, fibrous tissue encompases regenerating nodules causing a nodular appearance
cirrhosis
associated with aplastic anemia, glomerulonephritis, polyarteritis nodosa
Hep B
associated with metabolic disorders, cryoglobulinemia, glomerulonephritis
Hep C
combination therapies for Hep C
2
- glecaprevir/pibrentasvir
- sofosbuvir/velpatasvir
other based on genotype
first line treatment for Hep B
tenofovir, entecavir
