Marrowkidz Families 5-11 12-16 17-25 Anti-thymocyte globulin (ATG) treatment This factsheet is for children who need ATG as part of their treatment for aplastic anaemia. What is anti-thymocyte globulin (ATG) treatment? If you have aplastic anaemia, you might be given a medicine called ATG to help make you feel better. Your immune system works to keep your body safe and protect it against diseases and infections. With aplastic anaemia, your immune system can end up working too hard and begin fighting against your bone marrow inside your bones. This means that the bone marrow doesn’t make enough of the blood cells your body needs to keep you healthy. ATG is a kind of medicine that quietens down the immune system for a while. It gives your bone marrow time to get better and start making blood cells again. What’s in this factsheet? This factsheet explains what happens before, during and after ATG treatment. You can view or download the factsheet as a PDF here: Anti-thymocyte globulin (ATG) treatment (age group 5-11) Or order it as a printed booklet here.
