Well I recieved some dissapointing news today. The last test I needed to come back was my JCV antiboody test before I would have started back on Tysabri. Well my GI called today and I test positive for the antibodies....While this dosent exclude me from taking tysabri, some 70% to 90% of the population have the JCV virus, it does put a different perspective on things. So after talking with my doctor it looks like Im going to try a stint of Cimiza first and see if it does anything for me and if not Tysabri will be back on my list. Im a little discouraged as from what Ive read Humira and Cimiza are really similar and I never got any effect from Humira.
