Finally. I just found an article published this month, showing the efficacy of budesonide (Entocort) compared to azathioprine (Imuran) AND the results are verified via colonoscopies.
"Complete or near complete healing was achieved in 83% of azathioprine-treated patients compared with only 24% of budesonide-treated patients."
This is the first evidence I've seen that Entocort CAN cause mucosal healing. Dr. Abreu, formerly at Mt. Sinai, mentioned this study to us way back in September 2007.
