19
Q

Causes of normocytic anaemia? (7)

A 
Chronic disease
Aplastic anaemia
Haemolysis
Sickle cell
Leukaemia
Mixed Iron and B12 deficiency
Increased plasma volume e.g. pregnancy, fluid resuscitation after haemorrhage
20
Q

Causes of microcytic anaemia? (

A 
Iron deficiency
Thalassaemia
Sideroblastic
Lead poisoning
Chronic disease (but this is normally normocytic)
21
Q

Types of Macrocytosis and causes?

A

Megaloblastic:
- B12/folate deficiency or chemo - also presence of macroovalocytes and hypersegmented neutrophils

Non-Megaloblastic:

  • alcohol
  • hypothyroidism
  • pregnancy
  • liver disease
  • marrow failure
  • reticulocytosis
  • -> these can be assoc with anaemia or just isolated macrocytosis
22
Q

Causes of target cells?

A

Liver disease
Hyposplenism
Thalassaemia (alpha or beta)
Iron deficiency

23
Q

Cause of Howell Jolly bodies?

A

Hyposplenism

24
Q

Causes of Heinz bodies?

A 
G6PD deficiency
Alpha thalassaemia (HbH)
Chronic liver disease
25
Q

Intrinsic causes of haemolytic anaemia? (3)

A
  • Membrane problem - e.g. spherocytosis
  • Haem problem - e.g. thalassaemia, sickle cell
  • Metabolic problem - e.g. G6PD deficiency
26
Q

Extrinsic causes of haemolytic anaemia? (4)

A
  • Autoimmune - e.g. SLE, RA
  • Splenomegaly - any cause e.g. cirrhosis, Felty’s syndrome
  • Vascular damage - burns, vasculitis
  • Infection - malaria
27
Q

Common to both intravascular and extravascular haemolysis?
