Welcome to a site dedicated to those diagnosed with this rare and challenging autoimmune condition. EGPA occurs in 2-3 new cases per year per million people, which means you are selected with almost impossible odds to belong to this unique group! OK, not what you had in mind but...!

We hope these pages will help as you work your way through the many issues and questions. Moving along the menu above, from left to right, will help order things for you, particularly if you have been recently diagnosed.

If you are a friend or family of a newly diagnosed sufferer then stop off  here.

Why the Egg? EGPA stands for "Eosinophilic Granulomatosis with Polyangiitis!" To remind you of the acronym, our EGg Personal Assistant will appear on some pages!

Churg-Strauss Syndrome (CSS) is the old name, still used by many, but this is slowly changing, particularly in medical documentation.

You are not going to be left alone with these medical tongue twisters. There are new drugs, better treatments and many who have been there before you and are ready to help.
