HBV enters a 4- to 10-week incubation period
Initial or acute phase
Marks a decrease in HBV DNA levels with ongoing secretion of HBeAg.
immunoactive phase
HBeAg is replaced by Anti-HBeAg
Seroconversion phase
most prominent surface antigen and is detectable at the onset of clinical symptoms
HBsAg
High levels of antibodies are detectable during acute infections.
IgManti-HBcAg
If there is an infection and if it is proliferating, there should be _______
HBcAg
Patients who respond to vaccines will have ______ only.
anti-HBsAg
HBV vaccines

T/F: HBV infections are not curable
T
First-line therapy options for HBV

○ Telbivudine
○ Adefovir
○ Entecavir
○ Pegylated IFN-α2a
most common blood-borne pathogen
HCV
approximately five times as common as HIV
HCV
caused by an RNA virus from the flaviviridae
HCV
single largest risk factor for HCV infection is
injection drug use
Vast majority of cases are chronic hepatitis.
HCV
detected 1-2 weeks of exposure
HCV
No vaccine
HCV
inhibiting key viral enzyme, NS3/4A serine protease
BOSEPREVIR
Must be administered together with PGN-INF alpha and ribavirin
BOSEPREVIR
Inhibits HCV NS3/4A protease needed for proteolytic cleavage
TELAPREVIR
Specifically intended for patients with compensated liver disease such as cirrhosis
TELAPREVIR
DOCfor thrombocytopenia
Eltrombopag
Stimulates bone marrow platelet production to provide stable platelet counts toallow therapy with interferons
Eltrombopag
Antiviral nucleoside analogue
Ribavirin
Not effective when given alone
Ribavirin
Mean incubation period of HBV
1-4 months
Digests proteins
