PLEASE, a short course of Prednisone can be very effective for some people in moving them to remission. I'd just try not to have her on it for more than a few months at most, and watch for the side effects. If she goes on Pred, make sure she takes a calcium and vitamin D supplement to help protect her bones, and ask the doctor about
something like Fosamax to help prevent osteoporosis. I always took 500 mg. of calcium three times a day.
Since she doesn't seem to be going into remission, usually the next step is either Imuran (azathioprine) or Remicade. You can look both of these up on the internet, but don't let the listed side effects scare you too much. Most people don't get them, and the medications may give her back her life. At this point, she may want to consider taking this semester off to try to get healthy, and resuming in the fall. Trying to go to school and manage a bad flare may just be too much.
I hope you find the right combination for her very soon. I know what she's going through. It was hard for me at my age, and I can't even imagine going through it at 19. She's a brave girl.
