The condition and the treatment
Atypical haemolytic uraemic syndrome (aHUS) is a very rare, life‑threatening condition. It causes blood clots to form in small blood vessels throughout the body and also severe inflammation of blood vessels. This can damage vital organs such as the kidneys, brain and heart.
Eculizumab (also called Soliris) works by stopping blood clots from forming and preventing the inflammation.
