16
Q

What defines chronic viral hepatitis?

A

> 6 months

17
Q

What are the two key features of Hep A and Hep E?

A
  • Transmitted via faecal oral route

- Only acute (never chronic)

18
Q

What does serology indicate in Hep A and E?

A
  • IgM = ongoing infection

- IgG = cured

19
Q

Which has a vaccine - Hep A or E?

A

Hep A

20
Q

How are Hep B and C transferred?

A
  • Infected needles
  • Unprotected sex
  • Childbirth
21
Q

What % of people with Hep C get chronic infection?

A

80%

22
Q

What % of people with Hep C are asymptomatic?

A

70-80%

23
Q

What is cirrhosis?

A

Excessive fibrosis

24
Q

What can chronic Hep C infection lead to?

A
  • Liver failure
  • Cancer
  • Cirrhosis
25
Q

Which enzyme is more raised in Hep C?

A

ALT

26
Q

What is the best marker of Hep C?

A

HCV RNA (through PCR)

27
Q

Does HCV IgG mean you are cured?

A

No

28
Q

What is the treatment for HBV and HCV?

A

Antivirals

29
Q

What % of people with Hep B get chronic infection?

A

20% (If < 6 50%)

30
Q

What can chronic Hep C infection lead to?

A
  • Cancer

- Cirrhosis

31
Q

Who can Hep D infect?

A

Only people with HBV

32
Q

What are the 3 HBV antigens?

A

1) HBsAg (surface antigen) - most important
2) HBcAg (core antigen)
3) E antigen

33
Q

What does increased HBV E antigen indicate?

A

More likely to infect someone else (marker of replication)

34
Q

Without what are you not cured from HBV?

A

IgG-HBsAg

35
Q

How long does it take to produce antibody to HBsAg?

A

~ 6 months

36
Q

The presence of which antibody indicates you are cured from HBV?

A

IgG-HBsAg (either vaccinated or naturally cleared the infection)

37
Q

What is the only serology present after a vaccine?

A

IgG-HBsAg

38
Q

What does HBcAg/IgG-HBcAg indicate?

A

Infection with HBV - IgG-HBcAg is not effective but indicates infection

39
Q

What is the core window?

A
  • When you don’t know what will happen

- Only IgG-HBcAg is present
