The lifelong sequelae of dealing with a bone marrow transplant as a reboot seems to offset gains in food allergy, honestly.
The other thing to bear in mind is that people have trouble enough getting BMT's when they are literally going to die without one.
There is a lot of experimental treatment now crossing over to clinical practice. Some of that is quite controversial at the moment-- most of the leading experts in food allergy (worldwide, mind) believe that such oral desensitization protocols are dangerous and not ready for clinical practice, but they do seem to work well for some (maybe even majority) percentage of patients.
There are troubling reports emerging from the research studies, though, that indicate that not everyone can hold tolerance, and that it may NOT be 'normalizing' for the immune system in all patients-- even among those that can tolerate the protocol in the short term (well, it's like allergy shots, so it's pretty long term as treatment regimens go).
Interesting stuff, to be sure. But scary, when you dig into it-- I feel very fortunate that we have the kind of allergist we do, and that he is on a first-name basis with some of the top researchers in the world. He picks stuff up early, and warned us off of this (in light of my DD's particular history, she seems on an anecdotal basis to be a likely disaster under such a protocol) about four years ago when it started to get hot with clinicians eager to to SOMETHING for patients.
