[Autoimmune hemolytic anemia during pregnancy. Apropos of 1 case].

A case of auto-immune haemolytic anaemia during pregnancy is described. The different tests carried out on the patient make the diagnosis of idiopathie auto-immune haemolytic anaemic haemolytic anaemia in this case. Several theories have been reviewed in order to try and explain the possible role of pregnancy in the appearance of worsening of this kind of anaemia. The theory most likely to be true is that it is a slowly evolving process of auto-immunisation in which the haemolytic effect was accelerated by the pregnancy and showed itself clinically because of the haemodynamic factors occurring at the placental site.
