- is acute and self limiting in adults
- can be asymptomatic in children
HAV
A= acute, asymptomatic
- intially presents like serum sickness (fever, arthralgias, rash)
- may progress to carcinoma
2
HBV, HDV
may progress to cirrhoisis or carcinoma
HCV
C=cirrhosis, carcinoma
fulminant hepatitis in pregnant patients
HEV
E=expectant mothers
high mortality in pregnant patients
HEV
pose of risk of progressing to HCC

HBV
HCV
HDV
adults mostly experience full resolutions, but neonates have a far worse prognosis
HBV
HDV after HBV is called
superinfection
poor prognosis
HDV with HBV is called
coinfection
biopsy shows
- hepatocyte swelling
- monocyte infiltration
- coucilman bodies
HAV
biopsy shows
- granular eosinophilic “ground glass” appearance
- cytotoxic T cells
2
HBV, HDV
biopsy shows
lymphoid aggregates with focal areas of macrovesicular steatosis
HCV
biopsy shows
patchy necrosis
HEV
which hepatitis virus does not have a carrier state?
2
HAV, HEV
A= absent carrier state
carrier states are common for which hepatitis viruses?
2
HBV, HCV
depends on HBV HBsAg coat for entry into hepatocytes
HDV
D= depends on
- enteric
- endemic to Asia, Africa, Middle east
HEV
E= enteric, endemic
lack an envelope and are not destroyed by the gut
