definition• Jaundice (or icterus) is a term used to describe the yellow

pigmentation of a patient's skin and sclerae caused by excess bilirubin in the blood.

• Jaundice become visible at >35umole/L

• Jaundice is not itself a diagnosis and the cause should always be sought.

• Many diseases cause jaundice through a variety of different mechanisms.

Classification & causes

Pre-hepatic hepatic post-hepatic

haemoglobin bile duct

breakdown

Hepatocyte

Unconjugated

bilirubin conjugation

Liver uptake conjugated

bilirubin

Prehepatic jaundice:

excess production or failure of uptake into liver

• Haemolysis, eg G6PD deficiency

Autoimmune

• Congentital hyperbilirubinaemia eg Gilberts,

Hepatocellular jaundice

Hepatocyte failure / damage (ALT>ALP)• Alcohol• Viral Hepatitis A, B and C, EBV• Cirrhosis• Drugs • Auto immune• Hepatoma• Metastases• Wilsons• Hepatic congestion from cardiac failure

Chronic liver disease• Alcohol & viral hepatitis are the most

common causes of chronic liver disease and cirrhosis.

• Develop when the functional capacity of the liver can no longer maintain normal physiological conditions

• Jaundice is a feature of chronic liver disease

Cholestatic jaundice

impaired excretion of bile (ALP>ALT)• Gallstones• Head of pancreas cancer• Porta hepatis lymph nodes• PBC• Sclerosisng Cholangitis
