Well, the question of moving up the ladder to a biologic has been an ongoing topic for the last couple of years; unfortunately, last year we found out I don't have any antibodies against measels (received only one shot as a child) so that my doc wants me to stop the Azathioprine first, get the vaccine and then try a new medication. I am right now in the process of finishing my dissertation so I keep postponing since the possibility of getting a big flare when tapering/stopping the Aza is not very encouraging.
Had my last scope in May, all fine, only the sigma-rectum area they found "increasing vascular drawing", but assumed that might be related to the preparation. Biopsies showed no inflammation, no ulcers, no bleeding etc. Actually, the final letter said "full remission".
