Hi - I have just the opposite information. Remicade has greatly helped my AS and my Crohn's. In fact, remicade is the drug of choice for the Crohn's when asacol doesn't help. So it makes me wonder if it works so well for Crohn's, then why wouldn't it help with colitis? I know they are different but aren't they alike in lots of ways too? Remicade literally has given me back a life when it comes to the AS. Maybe you could get a second opinion from another rheumatologist.
