Do check out the Vasculitis Foundation website:
Vasculitis Foundation It gives a list of Vasculitis centers, names of specialists etc. - so glad your thoracic surgeon suspected Wegeners and diagnosed it too. But he's probably not a specialist at remission and maintenance therapies. Your rheumatologist might have treated several Wegeners patients, and may be on the list. It's unfortunate you're far from him - won't hurt to find a local rheumatologist who can coordinate your care with a specialist in Toronto.
Several of us on this forum have responded very well to Rituxan, to bring us into remission. Some of us, including me, even get it for maintenance therapy. I've had no noticeable side-effects from it. I also took Bactrim (to prevent pneumonia) and protonix to prevent heartburn from prednisone.
Anyhow, good luck and hope you get to see the doc soon!
