EBV
CMV
Rubella

3
Q

5
Q

What are the methods of assessing chronic hepatitis?

A

Blood tests
Viral load
Grade and stage
Fibroscan

6
Q

What is the only DNA hepatitis virus?

A

B

7
Q

What hep B antigen is present when the virus is replicating?

A

HBeAg

8
Q

What causes damage to the liver in hep B?

A

Body’s immune response

9
Q

What are the signs of active hep B infection on serology?

A

HBsAg
IgM anti-HBc
Viral DNA
High ALT

10
Q

What are the signs of resolved hep B infection on serology?

A

Anti-HBs

Anti-HBc

11
Q

What are the signs of hep B vaccination on serology?

A

anti-HBs

12
Q

What are the infection phases in hep B?

A

Replicative, immune tolerance
Replicative, immune response
Non-replicative, immune control
Replicative, immune escape

13
Q

Who is most likely to be in the replicative, immune tolerance phase of hep B?

A

Infants who were exposed perinatally

No immune response so asymptomatic

14
Q

What happens in the replicative immune response phase?

A

Tolerance wanes, or happens if infected is an adult

Immune system begins to seroconvert HBeAg to antibody

15
Q

What is the non-replicative immune control phase?

A

Asymptomatic carriers; virus is no longer replicating

disease progress halted

16
Q

What happens in the replicative immune escape phase?

A

Reactivation due to mutant strain or immune suppression

17
Q

Which hepatitis antibodies are protective against getting the same virus?

A

A is protective

C is not

18
Q

How many serotypes of hep C are there?

A

6

19
Q

What is the goal of hep C treatment?

A

No RNA detected 12 weeks after treatment
