Welcome to the forum. You are lucky to live in the SF area. There may be several good GPA doctors in the SF area, but the one I've heard recommended most often is Sharon Chung at UCSF medical center. You will find her listed with other specialists on the Vasculitis Foundation website. I think it is also possible that you have MPA, which is closely related to GPA, and I believe also shows positive ANCA. And there may be another one in this category. A specialist would know the distinctions, but in all likelihood the treatment will be the same. Especially if kidneys are involved, you need to get a diagnosis from a specialist so you can get treated with more than just prednisone. There are various immunosuppressants that are used. Good luck and keep us posted.
