Parenteral: Hep b, c and D
Oral/faecal: Hep A and E

4

What is unique about hep D?

It can only be acquired by someone also infected with active Hep B - cannot replicate without it

5

What are the 3 routes of transmission for viral hepatitis?

1) Oral/faecal
2) Parenteral
3) Blood Products (e.g. transfusion - parenteral also)

6

What are the common symptoms of viral hepatitis in the prodromal phase?

Flu-like symptoms: nausea/vomiting, malaise, fatigue, anorexia, low-grade fever, myalgia, mild headache.

7

It is another term for jaundice and the associated symptoms

8

What are the common signs & symptoms of viral hepatitis in the icteric phase?

- jaundice - itching (pruritis) - abdo pain - dark urine - pale faeces - arthralgia and skin rash

9

List 3 other differeintials you ought to consider with the icteric picture.

1) Acute HIV infection
2) Acute drug-induced liver injury (e.g. paracetamol/ecstasy etc)
3) Drug-induced hypersensitivity reaction e.g. sulfasalazine hypersensitivity

10

What are you likely to see/find on examination in someone presenting with viral hepatitis?

jaundice - sclera first then skin; hepatomegaly; temperature of up to 40; features of chronic liver disease; evidence of decompensation

11

List some signs consistent with decompensated liver disease.

Encephalopathy - drowsiness, liver flap, hyperventilation
Excretory dysfunction - jaundice
Portal HTN / hypoalbuminaemia - ascites, peripheral oedema, leukonychia
Coagulopathy - bruising
Acid-base imbalance - respiratory acidosis

12

Where is hep B more commonly found globally?

Central Africa and China & SE Asia
Globally a huge problem - approx. 2 deaths a min!

20

What are the aims of Hep B (HBV) therapy?

1) Loss of: replication, e antigen, surface antigen
2) Normalisation of transaminases (ALT and AST)
3) Improve of liver histology
