Differnece beween PAnca Vasculitis and Wegners?

[pberggren1]

I have no idea.

P-ANCA = Microscopic polyangiitis (MPA)-- affects small blood vessels; vasculitis without granulomas

C-ANCA = Wegener's/ Granulomatosis with polyangiitis (GPA)--affects small and medium blood vessels; granulomas + vasculitis

They are treated the same.

However, you can be p-anca positive, and have Wegener's. It's rare, but does happen. Lucky, lucky ME for example!

[Sangye]

Yes, you are unique for sure!

[Chris G]

Hmmmm, I'm sure you meant that in the best possible way!!

I find this very confusing. My blood tests say ANCA- MPO and ANCA- PR3, both are usually positve. I do have a lung nodule, brain MRI shows sinus involvement, stage 3 kidney disease, and some other problems. I have not had any biopsies. My doctor just says vasculitis - can you have both types? Do you happen to know how high the ANCA factors(scores?) can get?
