What is aplastic anaemia?
Aplastic anaemia is a rare and life threatening condition caused by the bone marrow not functioning properly.

In people with aplastic anaemia, the bone marrow fails to produce enough of all three types of blood cells – red, white and platelets.
Aplastic anaemia treatment is very similar to the treatment someone might have for leukaemia - but because it's so rare, families often don't have access to the same information and support.

The Aplastic Anaemia Trust is the only charity in the UK dedicated to supporting people affected by aplastic anaemia and funding research into this rare form of bone marrow failure.

By donation you'll be....

Providing support
Provide a young child with a story book that explains what aplastic anaemia is and what they can expect from a long stay in hospital - making the long and difficult treatment less frightening.

Make sure there is always some one on the end of the phone. Having someone to talk to who understands, who you don't have to explain your condition to again and again. The AAT support line ensures no one is alone.

Funding Research
In December 2024, the news came out that a clinical trial that The AAT is funding is showing promising results with a brand new treatment for AA.

This year, They'll be publishing a paper setting out the current priorities for clinical research in aplastic anaemia. Those priorities will require The AAT to raise more money for research than they've have ever raised before.

Research can improve the way AA is treated, not just for future patients “some day” far off – but right now. In recent years, research has told us how people with AA respond to the Covid vaccine, and demonstrated the benefits of eltrombopag alongside standard immunosuppressants, and now they're trialling brand new treatments!

If The AAT don’t fund and enable research into aplastic anaemia – no-one will. 

That’s why I'm asking you to donate for the future of AA research.
