My daughter was finally correctly diagnosed when she was 18, in 2006. We found that the modified version of SCD diet ("modified" in this case means cheating by eating potatoes and rice: based on our experience I do NOT recommend - better to stick to strict SCD) combined with Entocort, a steroid that is released mainly in the intestine, so not as much of it gets into the bloodstream, resulting in far less side effects than prednisone.
We were shocked to see her stricture disappear just with the Entocort and diet. No symptoms but her labs and a colonoscopy showed very mild inflammation. So she introduced LDN, which combined with just one pill of Entocort and the modified SCD, brought her labs to the normal range. She used the LDN to successfully taper off Entocort (previously, she had landed in the hospital when tapering) and then, for a year, enjoyed the best health of her life - not even a sniffle. When she tapered off LDN, within two weeks she got a very bad cold lasting three weeks. And her symptoms came back. Also, the LDN, combined with modified SCD but without Entocort, did NOT bring her labs to the normal range.
Right now, she is slowly tapering off Entocort, and will try Pentasa for the first time and/or LDN again. This time, with strict SCD.
So far, we have not regreted the decision to forgo the more toxic meds. When she had mono and her spleen was enlarged, we were glad her body didn't have to deal with the virus AND toxic meds.
Right now, she is battling a bacterial skin infection caused by one of the "bad bugs," so I'm still thankful she's not on a heavy immunosuppresant, which could have turned this into a far more serious situation.
