That is the hope of Olle Kämpe, who is a clinical researcher at Karolinska Institutet. It is not known what initiates an auto immune reaction, just that it starts several years before the patients come to clinical care. Kämpe and his group has discovered that the immune system in all patients with Addison's disease reacted to the very same substance – the enzyme 21-hydroxylase. Kämpe and this team are working on a promising treatment for patients with Addison's. You’ll meet Olle Kämpe and his patient Eva Raffner.
