Anaemia Flashcards
name 2 causes of microcytic anaemia
Iron deficiency
thalaseamiea
Blood film of iron deficiency anaemia. Which cells will be seen
Rod cells (pencil cells)
name 2 causes of macryocytic anaemia (megaloblastic anaemia). WHY is this the case
B12 deficiency and Folate deficiency
- B12 and folate are essential co-factors for nuclear maturation.
microcytic anaemia due to problem with
- cytoplasm
- nucleus
Cytoplasm
Macrocytic anaemia due to problem with
- cytoplasm
- nucleus
Nucleus
- abnormal nuclear maturation (nucleus fails to divide)
Most common cause of B12 deficiency
Pernicious anaemia
Name 4 causes of B12 deficiency
Pernicious anaemia
Vegan
Gastrectomy
Coeliac disease
Where is B12 absorbed
ileum
Where is folate absorbed
Jejunum
Which auto-antibodies do you check for in ?pernicious anaemia
anti Gastric parietal cell
anti Intrinsic factor
How do you manage pernicious anaemia
Vit B 12 injections for life
What is spurious macrocytosis
Name 2 causes
Volume of mature red cells is normal
but MCV is measured as high
Reticulocytosis (bigger than mature cells)
Cold agglutains
Name an example of a normocytic anaemia
Anaemia of chronic disease
Anaemia of chronic disease
- transferrin (increased/reduced)
- serum ferritin (increased/reduced)
Transferrin - reduced
Serum ferritin - increased
Haemolytic anaemia
- microcytic/normocytic/macrocytic
Normocytic
What will blood film of haemolytic anaemia show
Polychromatic red cells
- due to increased reticulocytosis
Heinz bodies makes you think
G6PD deficiency
Which kind of inheritance is G6PD deficiency
X-linked recessive
Microcytic anaemia means
- nucleus problem
- cytoplasm problem
Cytoplasm problem
Macrocytic anaemia means
- nucleus problem
- cytoplasm problem
Nucleus problem
Which kind of anaemia is thalassaemia
Microcytic anaemia
Target cells on blood film suggest (2)
Iron deficiency anaemia
Splenectomy
Rod cells on blood film suggest
Iron deficiency anaemia
Stores of folate / B12 last longer?
B12 - lasts 2-4 years
Folate - lasts 4 months
