X2 same here for myself, I'm on a weekly Plasma Exchange/Apheresis now for the last 18 months, 78th exchange so far and keeps me a float, I was at one time doing a double wamie Plasme a.m. then IVIG p.m.and didn't see much improvement, IIVIG wasn't very eeffective so I stopped doing them, plasma exchange is much more effective but only lasts 6 to 7 days Max...I'm also on Imuran that took 8 mouths to kick in and was finally able to start weaning off Prednisone and that another story! I also take Mestanon.
