I think you will find this helpful, especially the treatment protocol.
I would not have gone the prednisone way personally, because although you might be seeing improvement now it is probably ony a quick fix. And you are not getting to the underlying problem.

It is important you keep good bacteria in the gut, and limit fats and fiber. I would personally get the enzymes into play and feed 2 meals daily along with dyne to supplement needed calories.
