|
Hepatitis A
|
acute infection only
flu like symptoms in adults often asymptomatic in children usually travelers - fecal oral route problem in people with chronic liver disease vaccine |
|
Hepatitis E
|
severe acute hepatitis - no chronic infection
more severe than Hep A 20% mortaility among pregnant women often see in outbreaks |
|
Hepatitis B
|
DNA virus (only one of the hepatitis viruses)
|
|
Hepatitis B Core Ab IgM
|
indicates acute HBV
|
|
Hepatitis B Surface Ag
|
indicates infection (acute or chronic)
|
|
Hepatitis B Surface Ab
|
indicates immunity to Hep B
|
|
Hepatitis B E Ag
|
indicates active replication (and usually active hepatitis)
|
|
Hepatitis B E Ab
|
seroconversion
|
|
Hepatitis B DNA
|
high titer correlates with viral activity and risk for hepatocellular carcinoma
|
|
perinatally acquired chronic HBV
|
Surface Ag+
high serum HBV DNA ALT is normal HBx - minimal inflammation can serocovert: E Ag-, E Ab+, low HBV DNA |
|
adult acquired chronic HBV
|
S Ag+, E Ag+, high serum HBV DNA
elevated ALT, HBx-, active inflammation |
|
inactive (carrier) chronic HBV
|
S Ag+ > 6months
E Ag-, E Ab+ ALT normal low HBV DNA |
|
HBeAg- chronic hepatitis
|
mutant virus that doesnt produce E Ag
E Ag-, E Ab +/-, S Ag+ high serum HBV DNA, elevated ALT, active inflammation |
|
Hepatitis D
|
Needs concurrent HBV infection - for viral coating
coinfection and superinfection - more sever hepatitis |
|
causes of acute hepatitis in HBsAg+ person
|
acute HBV infection
Superinfection seroconversion HBeAG-> anti-Hbe HBV reactivation non-viral liver injury |
|
Hepatitis C
|
most often becomes chronic viral hepatitis
route of infection - blood - tatoos, needles (not usually sexual) EtOH and HCV dmg is synergistic |
|
Hepatitis B labs
|
acute infection see HCV RNA
HCV Ab to diagnosis ALT will go up and down |
