[Paroxysmal nocturnal hemoglobinuria in pregnancy].

The combination of paroxysmal nocturnal haemoglobinuria (PNH) and pregnancy occurred in three women aged 29, 31 and 35 years. One patient had a spontaneous abortion twice after which she committed suicide. In the other two the pregnancy and parturition--assisted--were without complications. However, one woman developed post-partum abdominal crises. The children were born at term and healthy. PNH is a rare form of haemolytic anemia. Pregnancy causes lethal complications in 6% of the cases of PNH, while 30% of the pregnancies end in spontaneous abortion or stillbirth. Accurate monitoring of pregnancy and the puerperium is essential.
