Influence of previous blood-transfusion on incidence of pre-eclampsia.
The incidence of pre-eclampsia in 125 primigravidas who had previously received blood-transfusions was significantly less than in a matched series of controls--i.e., 12.8% compared with 23.2%. This suggests that immunological factors may be involved in the aetiology of pre-eclampsia.
