I think my old thread is in the archived board, so I'm starting a new one. For those that are new to the story, dd had contact ana PA only and underwent OIT in Dallas with Dr. Wasserman's clinic 3 1/2 years ago. She did great with only one moderate reaction the entire time we were up dosing, when we switched to whole PN's. She's been on 1/2 tbsp PB daily maintenance dose for 2 years now.
At the end of the updosing, repeat labs showed a first time ever walnut and pecan allergy (labs immediately prior to treatment had been negative to everything but PN.) She'd eaten baked pecans in the past with absolutely no problem, and not alot of opportunity to eat raw ones. Since then, we've had a few episodes of itchy tongue with hidden raw pecans and walnuts. Honestly, we haven't fed her any baked ones on purpose, so I'm not sure if she'd react.
She's had itchy tongue symptoms two days in a row to certain cheeses from an organic, artisanal cheese place. Looking into it, I think it was due to the probable high histamine content of those types of cheeses - alpine cheeses can end up that way sometimes. Could have been x-con also, though, since this place also has a pecan pesto they put on some sandwiches.
She's had one PB reaction, just recently, involving swelling of her eyelids about an hour after her regular PB dose. She has NEVER reacted since she started maintenance dosing. She had been outside all day all weekend, and our pollen counts are thru the roof right now, and she had a raw spot on her gums from her braces. During up dosing we learned that if the PB sat too long against her gums she'd have localized swelling. So, too much direct exposure +/- an immune system that had been overloaded? Decreased tolerance? During that episode she also had a mild, infrequent little cough. No, I didn't epi her, but thought about it. No problems with the next day's dose or any since.
She has an appointment with the allergist in 2 weeks. I just got her labwork back. Here it is:
PN 0.64 class 1
Pecan 6.64 class 3
Walnut 7.20 class 3
Sesame 0.65 class 1
Cashew 0.44 class 1
Pistachio 0.66 class 1
Hazelnut 0.83 class 2
I'm pretty sure all those other nuts have always been <0.35. Ergh. She's had Nutella in the past without a problem, but we haven't had any in a few months. I'm going to get her some and see what happens. She's also had hummus many, many times without issue.
Much to discuss with the allergist.
