Anti-E in pregnancy.

Since the introduction of anti-Rhesus (Rh) D prophylaxis for RhD-negative women, other Rh and non-Rh red cell alloantibodies have become relatively more important and are now responsible for the greater proportion of haemolytic disease of the newborn. Anti-C and anti-E are the most commonly implicated non-D Rh antibodies in the pathogenesis of haemolytic disease of the newborn'. In 1977 Pepperell et al. reported the outcome of 44 women with anti-E. This is the only published series that investigates the implications of anti-E during pregnancy. The present report presents a retrospective study of the outcome of 122 pregnancies in which anti-E was the sole alloantibody detected.
