May have outgrown allergy!

Just a quick note to let all of you know that my son may have outgrown his PA. Two years ago he was a 4+ and this week he retested at a 2+. He will have an open challenge in 6 months when he turns 5. We are cautiously optimistic. I will let you know what happens. Alicia

Does a 2+ mean that he has outgrown PA? Wouldn't testing a Zero (0) mean that he has outgrown it? Just curious as I don't know.

I'm just curious as well as to why just because his numbers have come down your allergist would think that he has outgrown it? Also, is this the class your referring to? TIA

The 4+ to 2+ was on the skin test. 2+ is considered negative. My understanding is that the skin scale is 1+ to 4+ with 1 & 2 being negative and 3 & 4 positive. Someone correct me if I am wrong!His Rast was also negative. He has had no reaction since diagnosis so she comfortable ordering the challenge. Alicia

Thanks! Wishing you and your son all the best in his upcoming challenge. Keep us posted on the outcome.

Thank you for explaining! Keeping fingers crossed that all goes well with the food challenge. Good Luck [img][/img]

Please let us know how it goes.

I hope 2+ is negative because my daughter was 2+ and that took 30 minutes. At the normal 15 minutes, her test was ZERO. The year before, it was 4+. Her allergy appt is today (a new allergist) - I am going to ask for a blood test. I am hopeful for both of us!

If there is ANY reaction on the skin, wouldn't that indicate a positive reaction?

My son was given an oral challenge but only after the skin test showed NO reaction at all. Had there been any redness, swelling etc. the doctors wouldn't have given him an oral challenge.

I would be a little leary about taking the challenge if he still is a 2+. Sometimes a 4+ can have the same reaction as a 2+.

Good luck and keep us posted.

Sandy, I think you may be thinking about Rast classes. I have heard that with rast classes that a 2+ can be as severe as a 4+, but Jake's rast was 0. I have always heard that skin classes are different. If you have heard otherwise, I apologize. I guess it goes to show how much contradictory info is out there. 'Alicia

I just did a search and read a bunch of articles, etc. and this is copied and pasted from one....

"Skin tests

One type of skin test is called a skin prick test. This test is done by placing a drop of a solution containing a possible allergen on the skin, then puncturing the skin under the drop with a needle to introduce the allergen solution into the top layer of the skin. If the skin reacts to the allergen with a red, raised itchy area (called a wheal), it usually means that the person is allergic to that allergen. This is called a positive reaction."

All the articles I read say that if the skin turns red, swells or develops a wheal it is considered positive, and that the skin test is considered more reliable than the rast.

Not trying to bring you down, I think we are all just concerned that your child may have serious problems during this challenge. You may want to get a second opinion.

Alicia, I will let you know that be careful with those tests. My daughter's allergist told us that 99% peanut allergy is lifetime. In addition that when is diagnosed, unless is very low the blood test, it is very rare that the person outgrow it. This is not a discourage but I will not try to give her/him anything with peanuts. The body can react worst. Good luck and hope he/she can outgrow it. Take a secord opinion from a pediatric allergist specialist. Take care

I have to respectfully disagree with the allergist who stated 99% of peanut allergies are for life. This may have been the prevailing thought 10 years ago, but numerous recent studies have shown that 20-25% of those with PA can outgrow it (depending on their age at the time of their first reaction and a low CAP RAST score).

Good luck with challenge. I wish your son the best.

That is exciting news! I am trying so hard not to hope that my DD outgrows her allergy, because I would hate to be let down, but stories like yours do let some hope slip in ;-) Best of luck with your test -- please let us know, either way, when you do it.

I appreciate all of your responses and concern for Jake. Of couse I am concerned as well, but I do think that it is the right thing to do. Despite the 4+ when he was diagnosed, his reactions consisted of flushed cheeks or a few hives on his ankles usually 12 hours after a PB sandwich. In fact he ate peanut butter for at least a year with no anaphalactic reaction and we just were ignorant as to what was causing his flushed cheeks and occasional hives. Jake has sensitive skin, so I expected his skin test to not change, but this time there was no wheal or swelling, just a little pink/redness smaller that a dime. Incidentally, it was not that much different that the negative control. I suspect thats why it was a 2 instead of a 1. I have read your skin test can remain positive after outgrowing for a few years. Anyway, JMO, given the negative rast and history of reactions I would rather know if he has outgrown it before he enters school. I know that he may not have, but I think knowing is worth it. My allergist is a top researcher and recently talked to Dr. Sampson about food allergies. She plans to be involved with the clinical trials of the "vaccine". I trust her and feel comfortable doing a challenge in her office. BTW, a little boy in our church just completed the challenge and has indeed outgrown his. He now eats PB almost every day, so there is hope. If it turns out not to be so for Jake, I am o-kay with that too, but I dont want to restrict him from may contains such as homemade chocolate birthday cakes due to cross-contamination if there is no reason to. I am sorry I am rambling! I respect all of your opinions and understand your concern. I will let you know what happens. Thanks, Alicia

Alicia, Yes, I meant a Rast test. Not a skin test. But what I meant to say was that a skin test can say 0 but indeed it could have a bad reaction like a 4+.

take care, Sandy

Alicia, I think you are doing the right thing with Jake. And I don't think you need a second opinion from another doctor. I have participated in some of the research studies that your allergist has done, and I know she would never even consider a challenge unless she thought it was appropriate. Don't have any doubts or regrets about challenging Jake. If I was in your shoes, I would definitely challenge. Why should he miss out on Birthday cake and such-I wish you lots of luck....

I hope all goes well for both of you, it sounds as though it may be promising, but just be cautious. This is the scoring I have recieved from two different allergists on skin tests. Grading System: 0-1< No allergy detected 2< Possible allergy detected 3-4< Probable allergy Again, good luck and warm wishes.
