Q

In patients with chronic HBV, what serological (plasma or serum) markers are detectable for life?

A

HBsAG and IgG for HBc

19
Q

When is it appropriate to start treating chronic HBV?

A

When there is evidence of liver injury….meaning high ALT

20
Q

What are the treatment goals of chronic HBV tx?

A

Decrease replication and minimize liver injury.
Reduce the risk of Hepatocellular carcinoma

Unfortunately, chronic HBV can only be cured in approximately 5-10% of pts.

21
Q

All HIV fts should be tested for HBV. There chance of natural clearance is lower

A

ok….the good news is that some anti-HIV drugs, like Tenofovir, are also anti-HBV.

22
Q

HBD is transmitted parenterally or enterically>

A

Parenterally…Needs the HBsAG to infect

23
Q

Super-infection

A

When a person with CHRONIC HBV becomes infected with HDV

24
Q

Co-infection

A

Just acute HBV and HDV infection occuring simultaneously
