My ds's allergist just called. His peanut Rast is 0.19. It has steadily decreased over the years. His first reaction was ana. when he was around 15 months. He has asthma, but it's pretty well controlled right now with a pretty heavy dose of Flovent. He has outgrown egg, wheat and dairy allergy.

The doc said that he has a 75% chance of passing the challenge. She also said that most hospitals consider >.35 as negative, but they are a very conservative hospital and consider >.10 as being negative.

Ds is entering kindergarten in the fall. I do not have to tell any of you the joy and relief we would feel if he has outgrown. But I'm also extremely scared of what type of reaction he could have if he does not pass. Could he die? What numbers could they shoot up to if he does not pass?

And last, but certainly not least, what would YOU do if he was your child?

Thanks so mcu for answering SOOOO many questions. You all are the best!!

mistey, have they skin tested him as well? While its good that his numbers have gone down, I myself might want to see a skin test before an oral challenge. But honestly, I don't know the true protocol, as we have no current hopes of low numbers.
I hope you find some good advice from others here....

Hi mistey -
Since you asked what I would do, I'll start there. I would not take the challenge yet. I'd wait at least another year to see if the downward trend continues.
I know it would be great if your son could go to kindergarten without having to take percautions, but even if he passes, you'd still need an epipen (I think it's generally recommended that a patient carry an epipen for a year after a successful food challenge.) And I know that even if my son were to pass, I'd still stress about a possible reaction if my kid was eating peanut products at school. But if he's not eating peanut products at school, then it's just as easy to treat him as PA anyway.
But if you do decide to challenge, I think you can trust your medical team that a fatal reaction is very very unlikely. I don't know about his numbers being affected, though - that would concern me.
Any challenges I'd agree to would be very conservative - I think I'd start with just a contact test, with exposure to intact skin.
But it's great news that your doctor is willing to even consider a challenge - hope your son has truly outgrown!

If this were my son with those levels....I would go for the challenge. I would start with contact first and see how he does. If all is fine, no reaction, then I would do an ingestion(ONLY in the allergists office or at the hospital though). But his levels seem very promissing. Also the fact that he's outgrown the other 3 allergens, it really does seem possible.
If you are not ready just yet, you could wait another year. Just take necessary precautions at school until you know if he's outgrown or not. Good luck [img]http://uumor.pair.com/nutalle2/peanutallergy/smile.gif[/img]

Personally, I'd absolutely do it! Since many (most?) challenge at 0.35 or below, I'd say at 0.19 you're pretty safe. I think a SPT first is a good idea, but I assume that's protocol?
I think if you do the challenge and he passes you'll save yourself a world of headaches and stress over this upcoming school year! If he hasn't outgrown it then he's in the safest place to have a reaction, and you'll know for sure. But given his history, it sounds like he's likely to pass (or at least that's what the allergist seems to be thinking).
But do whatever you feel comfortable with! If he does take the challenge, make sure to let us know how it goes. We'll be rooting for him!

based on my literature review and what has been written by Burks and Wood personally I would challenge- they challenge when 2 or less.(50-50 chance)
It would be totally life changing for school.
Again- this is only if it was my situation
This is a challenge in a controlled major medical center

Because it would be life-changing (in a great way) to learn that he is not allergic before he starts kindergarten and because he has a very good chance for a negative challenge, I would be really tempted to do the challenge before school starts. Since his numbers have been trending down, you are pretty sure the result is not a false negative, correct?
We subjected our PA DD to a peanut challenge at age 4 when her RAST was suposedly zero. This result turned out to be a false negative and she almost died. The challenge was not done safely.
You might want to repeat the blood test closer to the time you would do the challenge (?August) to be sure that it is truly negative before attempting the challenge.

BS312- please explain more about your challenge. I need to know what we are or or not getting ourselves into.

let me add to my comment if you challenge, have it done by a board certified allergist specializing in pediatric food allergies and who has much experience with food challenges- they are very controlled and done in a stepwise manner- again- in a major medical center. But, it is a choice you have to determine for yourself.

I was in a similiar situation with my daughter (now 7). Before she entered Kindergarten, her numbers had gone down to below what they considered an allergy. I was asked to put her through a challenge. Had your concerns, so I decided I'd wait a year. I was also told that if she passed the challenge, we should add peanuts to her diet little by little. I felt so uncomfortable about that part, especially since I had just had a baby and wanted to continue to keep our house peanut free until we figured out if the baby was allergic. Decided against the challenge--to wait another year. Unfortunately for us, the numbers shot back up higher than ever before on re-testing one year later--now a challenge is out of the question. I certainly do not wish the same scenario on you, but just wanted to share our story since I'm glad I waited.

I`ve always been stunned every time I read an article by Dr. Wood saying he would challenge if the chance of failing is 50%. There are many allergists who would not agree with that, definitely not ours. The main reason to do it would be so that when your child starts school, you would not really need to ask for accomodations if he passes. You could still make sure the lunch you send to school has no peanuts, but you would not have to ask for peanut free table, food free or nut free classroom, etc. It sure would make life a lot easier. I don`t think I would do it though with a 25% failure rate. However, what I`ve read shows a pass rate of higher than 75% with a cap rast of 0.19. I don`t recall the exact number.
