Remicade was developed as an RA drug, but since UC is also thought to be an autoimmune disease, it can also be used for UC. From what I've seen, it works very well for some people, but for others, it doesn't. My GI said he thinks that there are actually several different "causes" of UC, autoimmune being one of them, and that's why drugs work for some, but not all.
