The management of pregnancy in paroxysmal nocturnal haemoglobinuria on long term eculizumab

Br J Haematol. 2010 May;149(3):446-50. doi: 10.1111/j.1365-2141.2010.08099.x. Epub 2010 Feb 11.


In Paroxysmal nocturnal haemoglobinuria (PNH), pregnancy is associated with increased maternal and foetal complications to such an extent that the condition has been considered relatively contra-indicated in PNH. Eculizumab has revolutionized the treatment of PNH. We evaluate its use in pregnancy to date. We report on seven patients exposed to eculizumab at different stages of pregnancy including the first two patients to receive the drug from conception to delivery. There was no evidence of complement blockade from cord blood samples taken at delivery. Eculizumab appears safe to use in this setting and is likely to prevent many of the complications usually observed.
