For the ANCA versions of vasculitis (MPA, GPA and EGPA), I believe that Rituximab infusions are best. It seems to have quieted the disease moser completely for me than cytoxan. Everyone has to go through some form of high dose prednisone, usually long term, and the side effect from that are long and frustrating. But it shuts the immune system down and stops the disease from doing more damage, so it's a necessary evil.
