Pregnancy-associated atypical haemolytic uraemic syndrome in the postpartum period: a case report and review of the literature

Pregnancyhas been reported to be a trigger in about 10% of all patients with atypical haemolytic uraemic syndrome(aHUS). However, in contrast to pregnancy-associated thrombotic thrombocytopaenic purpura, the presentation of pregnancy-associated aHUS remains ill defined and can therefore be difficult to diagnose and manage appropriately. Here we report a case of pregnancy-associated relapse of aHUS in a patient with a previous medical historyof aHUS prior to pregnancy.
