Case 45 – update 1

So far we have a women who is 11 weeks pregnant and feeling tired and out of sorts. She has a microcytic anaemia and a borderline platelet count. Firstly let’s think about the anaemia. The two most common causes of anaemia in pregnancy are:

  • Iron deficiency
  • Haemoglobinopathy

Anaemia is exacerbated in pregnancy due to:

  • Increase in red cell mass
  • Blood loss
  • Increased maternal iron requirements
  • Iron needed by foetus and placenta
  • Dilution – increase in plasma volume

The MCV increases in pregnancy usully by 6Fl by about 26 weeks, so to have a microcytic picture would be unusual during pregnancy unless the patient has significant iron deficiency or a pre-existing haemoglobinopathy.

Questions:

  • What would you want to know before starting iron supplementation?
  • Are there any risks to iron supplementation?
  • When would you consider intravenous iron?
  • Which women are at risk of iron deficiency during pregnancy?
  • Why should iron be replaced? What are the risks of not replacing?
