That's what I was thinking, too, Ginger.
This sounds, in fact, EXACTLY like what our allergist has cautioned (and further; "worried") about with oral desensitization efforts being gradually rolled out clinically.
He really feels that NOBODY but the big league food allergy researchers have any business touching this one right now-- and that even then, it's potentially pretty risky. In his opinion, the people doing it have been pretty fortunate thus far.
I'm guessing that the underlying
reasons for that seeming "luck" have a lot to do with the fact that there's probably a minority of people with anaphylactic PA to begin with (this one is backed up by research even from 10yr back-- it's about 30% of people with a peanut allergy, apparently, but there's no way to know who is in that group clinically), coupled with the HIGH liklihood that many people currently labeled as "peanut allergic" may not be-- or may have such high threshold doses that they are effectively only "intolerant" in clinical terms...
So assume for the sake of argument that about half of contemporary diagnoses are "testing" based... that means that probably (at least) half of THOSE people aren't really allergic to start with... and that the other half contains only about 10% who are fairly sensitive AND likely to anaphylax.
Then there's my hypothesis, which is that people with very low (or worse-- moving/unpredictable) thresholds are rarer still--
it's not really much of a surprise that desensitization programs haven't run into one of those people just yet. There have probably only been a couple hundred people through PN desensitization programs anywhere in north America at this point. Our allergist's fear (and my fear, as well) is that
eventually, someone who doesn't know what they are playing with is going to be the unlucky practitioner who does.
