Background: Thrombotic microangiopathy (TMA) is a rare, life-threatening disorder characterized by microangiopathic hemolytic anemia, thrombocytopenia, and end-organ damage. Atypical hemolytic uremic syndrome (aHUS) is even less common, comprising less than 10% of hemolytic uremic syndrome (HUS) cases. aHUS in postpartum is associated with poor maternal outcomes, with the majority of cases resulting in end-stage renal disease.

Background: Atypical hemolytic uremic syndrome (aHUS) is a rare, life-threatening thrombotic microangiopathy (TMA) related to congenital mutations impeding control of the alternative pathway of complement. Following approval of the complement C5 inhibitor eculizumab by the European Medicines Agency and the US Food and Drug Administration, initial guidelines suggested lifelong therapy. Yet, growing evidence indicates that discontinuation of eculizumab, or its long-acting form ravulizumab, is possible for many patients.

Thrombotic microangiopathy (TMA) is defined by the typical triad of severe thrombocytopenia, hemolytic anemia and endorgan dysfunction and can be characterized by the pathophysiology of ischemia-inducing microthrombi in arterioles and capillaries possibly leading to severe organ dysfunction up to acutely life-threatening endorgan damage. In terms of etiology, management, therapy and prognosis, the following manifestations are distinguished: thrombotic thrombocytopenic purpura (TTP), shigatoxin-induced hemolytic-uremic syndrome (STEC-HUS), secondary comorbidity-related TMA and atypical hemolytic-uremic syndrome (aHUS). We present the case of a 49 year old lung transplant recipient developing aHUS.
