Study These Flashcards
A

Autoimmune e.g. SLE
Neoplasia e.g. CLL, Lymphoma
Drugs e.g methyldopa

18
Q

2 causes of cold haemolytic anaemia?

Study These Flashcards
A

Neoplasia e.g. lymphoma

Infection e.g. EBV, mycoplasma

19
Q

Causes of normocytic anaemia? (7)

Study These Flashcards
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? (

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

Types of Macrocytosis and causes?

Study These Flashcards
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

Study These Flashcards
A

Liver disease
Hyposplenism
Thalassaemia (alpha or beta)
Iron deficiency

23
Q

Cause of Howell Jolly bodies?

24
Q

Causes of Heinz bodies?

Study These Flashcards
A 
G6PD deficiency
Alpha thalassaemia (HbH)
Chronic liver disease
25
Intrinsic causes of haemolytic anaemia? (3)
- Membrane problem - e.g. spherocytosis - Haem problem - e.g. thalassaemia, sickle cell - Metabolic problem - e.g. G6PD deficiency
26
Extrinsic causes of haemolytic anaemia? (4)
- Autoimmune - e.g. SLE, RA - Splenomegaly - any cause e.g. cirrhosis, Felty's syndrome - Vascular damage - burns, vasculitis - Infection - malaria
27
Common to both intravascular and extravascular haemolysis?

Can become high-grade Non-Hodgkin's - watch and wait OR chemo
30
