Honestly, Christine, I can't think of anything else to try. I can't see that Lialda would be better than Asacol, since it's the same active ingredient and is designed to treat the entire colon. Do you think you could do a mesalamine enema at night and cortifoam in the morning?
trying Imuran instead of 6MP? I know they are essentially the same thing, but I think they are broken down a bit differently, so maybe Imuran would work better. It's a long shot, but you never know. When my doc and I were discussing the "what ifs" of future treatment, he said that he'd likely move me on to Remi (not at all suggesting you try it!) before trying Imuran or 6MP, but that if I wanted to try one of those first, he prefers Imuran over 6MP. Apparently, his patients have had more success with Imuran.
Like Judilyn, I'm also pretty sure that Humria, like Remicade, has the same TB issue.
I hope you find something that works!
