What are the treatments for aHUS?

Although plasma exchange and plasma infusion are sometimes used to manage aHUS, these therapies have not been studied in well-controlled trials.1


Historic Management Approaches2

Plasma exchange or plasma infusion is sometimes used by doctors to manage aHUS. During this process a plasma infusion is given over several hours at a specialized treatment center.3,6

However, plasma does not treat the underlying disease and no clinical studies have shown that plasma exchange therapy is safe or effective in treating aHUS.2,3-5 Plasma exchange/infusion is not a cure and symptoms may return over time.2,3,6,7

Dialysis or a kidney transplant may be needed for aHUS patients as a result of the damage caused by the disease. However, dialysis and kidney transplants have significant risks associated with them, and neither will actually treat or cure aHUS.8

Recent Advances

As the understanding of the underlying causes of rare diseases such as aHUS has improved, researchers are finding new, more effective and safer treatments. Talk with your doctor about a management plan that works for you and contains frequent follow-up or monitoring of your rare disease.
