Eculizumab in pregnancy-associated atypical hemolytic uremic syndrome: insights for optimizing management.

Abstract

Pregnancy-associated atypical hemolytic uremic syndrome is a systemic disease associated with high morbidity and mortality rates, caused by dysregulation of the alternative complement pathway, leading to uncontrolled complement activation resulting in thrombotic microangiopathy. This condition can be effectively treated by anti-C5 therapy, which controls complement activation. Treatment can be safely discontinued after complete remission and resolution of the precipitating cause, especially in patients with a low-risk genetic profile.
