[ArchivalUser]

yes B. She had HAV.

[ArchivalUser]

pt had hepatitis a

pt may be in the window period of hepatitis b

pt does not have hepatitis c

biliary cirrosis is not the cause here as it does not mention alkaline phospotase

Could the Patient HAVE hepatitis a infection. since chronic infection does not occir so a very high Ig g indicating an ongoing infection ? Any comments.

[ArchivalUser]

Could the ans be ' none of the above'....b'coz
1- pt has HAV IgG antibodies - so pt had hepatitis not 'has' HAV
2 - pt doesn't have hep B - we cant be sure of that as pt in window period will have HBsAG, HBeAg, HBcAg and Anti HBsAg negative
3 - tests for HCV not done - do cant say if pt has hep c
4 - PBC - presents with fatigue and pruritis. Jaundice, hepatomegaly and RUQ pain seen in 10% of pts. Need anti-mitochondrial ab for diagnosis. And they dont usually present with fever.

[ArchivalUser]

it should be "none of the above" and I think this pt might have tumor.

[ArchivalUser]

In the window period core antigen would be present, right?

[ArchivalUser]

NOT HEPB AND SHE HAD HEPA

[ArchivalUser]

I think both A & B are answers.
Correct me.
