Hey, guys!
I have AIH, and I was initially on 40 pred, with all the side effects--wt gain, high blood pressure, decreased bone mass, increased blood glucose, acne, ankle swelling, the whole works!.. I, too, couldn't tolerate Imuran due to severe nausea, fatigue. AND, even on the imuran, when they tapered the pred even a little, those enzymes just shot back up!!! My hepatologist gave me Cellcept, which was much less of a side effect problem (some intermittent nausea) but it caused large intestine damage (toxicity), The hepatologist just lowered the dose a little, and everything got better. Then, he gradually tapered and stopped the pred. I was on the pred for about one year, and I am still on 750 of cellcept, with normal liver enzymes!!! Also, my old energy is back and there really arent any side effects. (and, I lost the weight!!!!!)
So, there is hope, but be patient, because it takes a LONG time for the liver to recover . I do go to a hepatologist, not just a gastroenterologist, and this is a good thing, because treating AIH is an art form. As to cause, I had a cold just before, but no antibiotics, weird foods, environmental toxins or substance abuse. So who knows????
