There's been a few on the UC forum that had issues with latent TB. Here's one such instance:

Recap: Decided with my doctor to start Remicade because of persistent, mild, inflammation. But I failed by TB test. After waiting a month to see the infectious disease specialist, we did another test and it came back positive again (though just barely). Unfortunately, my travel history gave the doctor enough reason to believe that the result might be real, so he decided to treat the latent TB. He prescribed Rifampin for 4 months, but I was able to start Remicade after 1 month of treatment. I can not wait to be off the Rifampin. First, you are supposed to take it on an empty stomach (i.e. 1 hour before you eat or 2 hours after), but I've mostly given up on that, since I'd just forget to take it. It also interacts with birth control pills so they are less effective. And it can cause liver problems, so you aren't supposed to drink on it or at least not a first when they are checking your liver enzyme levels.

A user, Faithmac, on the UC forum went through this process. Pretty much the same story, been on humira and needed to switch to entyvio. Multiple positive tb tests, no signs of active tb, went to infectious disease doctor, and cleared to take entyvio recently.
