Learn about atypical Haemolytic Uraemic Syndrome (aHUS)

atypical Haemolytic Uraemic Syndrome (aHUS) is a life threatening disease with devastating consequences

It may be scary to find out that you or your loved one may have aHUS. Although aHUS is a life-threatening disease, learning about your disease is important. The more you know, the better you can manage it.1

Here are some key facts about aHUS:

  • aHUS is caused by genetic problems in the complement system, which is a part of the body’s immune system
  • aHUS is important to diagnose accurately because it has signs and symptoms that are similar to those of other diseases.2 Differentiating aHUS from other similar diseases as soon as possible is very important3,4
  • Plasma exchange/infusion has been used to manage aHUS symptoms, but plasma therapy has not been studied in well-controlled trials7
