Which of the following is most likely to account for
these features?
a)
Hereditary spherocytosis
b)
Warm autoimmune haemolytic anaemia
c)
Hepatitis A
d)
Gilbert’s syndrome
e)
Malaria
Answer: d)
Gilbert's syndrome
·
Mild unconjugated non-haemolytic hyperbilirubinaemia
·
Does not lead to hepatic inflammation, fibrosis, chronic liver
disease or liver failure
·
Genetic variant of the human bilirubin UDP-glucuronyltransferase
(UDP=uridine diphosphate glucuronate)
·
Unconjugated bilirubin rises in the absence of haemolysis
·
Reducing calorie intake increases bilirubin levels even in
normal individuals and this is aggravated in those with Gilbert’s syndrome
