Haemolytic anaemia of pregnancy.
Haemolytic anaemia apparently induced by pregnancy is reported in an otherwise healthy woman, with a negative family history. Folate deficiency, haemoglobinopathies, enzymopathies, hereditary spherocytosis, paroxysmal nocturnal haemoglobinuria, interstitial haematomata, hypertensive toxaemia, auto-immunity and infections were excluded. The autohaemolysis test showed increased lysis in the presence of added glucose. This abnormality was corrected by insulin when excess glucose was present, but not by insulin alone. It is suggested that this patient's erythrocytes may have been altered by placental lactogen and/or prolactin in such a way as to make them abnormally dependent on insulin for the uptake of glucose.
