Question about egg challenge???


My son's rast came back at 1.8 still class II and my allergist wants to do an egg challenge on Fri. Would you? I just wanted to know if he could eat things that possibly had egg whites in it like cake. Well, now she wants me to show up at the office with a hard boiled egg and a piece of angel food cake. Please what would you do? My husband wants to cancel it and put if off til next year. We are so scared something will happen to our little guy!

Did the allergist do a skin prick on him? I had a RAST of .53, got really excited, had a skin test, and the hive was bigger than a quarter. Not cool, definately still allergic.

So go to the doc, have the stuff with you, but demand an spt first. If his skin test comes back positive, then the decision will have been made for you. If it's negative, then you can decide if you want to do the challenge that day, or if you want to wait for the rast to go a little lower. Plus, while you're waiting the 15 minutes for the SPT, you can ask the doc questions and things to help you decide.

I don't recall if you ever mentioned his age, but if he's older than 3 or 4, don't forget to ask your son if this is something he wants to do. He might have a very strong opinion about it, so you'll want to have a talk with him before you decide anything.

My son is 2. His skin prick was tiny like 3 mm. I really am so confused about it. His peanut was huge like a nickel but his egg white was tiny. She had said lets wait til next year but I am the one that said can he eat things with eggs in it. Everyone I know whose child is allergic can eat things with eggs in it just not straight eggs. But she wanted to test him with a hard boiled egg and angel food cake. What would everyone else do? Please give me any advice you have!

i would wait. here is my experience -- at one, my daughter's skin prick was positive for egg (didn't do a rast); at 2, her rast was zero -- we challenged her (the allergist felt comfortable with "at home" challenge since the rast was literally zero). each time we fed her eggs (or something with egg in it, like pancakes), her eczema would flare up within 48 hours. could it be something other than the egg? possibly. but after about half a dozen times, we decided (along with our allergist) to forego eggs until her next rast. so, we went egg-free for another year. at 3, her rast was .67 (negative, but not zero); again the allergist felt comfortable with challenging her at home. she has been eating egg and egg products for 7 months now with no problem. i say, better safe than sorry. wait a year (i know it's a pain) -- give his little system time to mature.

I tend to agree with Shoshanna. It has been a year since my dd passed her egg challenge. She tested cat 3 at age 1 and at 2 1/2 she RAST tested 0 so we skin tested her and she was ok. Then we skin tested her again and then after she passed that followed up with a food challenge that same day at the Dr's office. We have been able to reintroduce so many foods with success I believe because of total avoidance and alternative med approaches. Most of the time, we didn't even have these foods in th ehouse because I didn't even want her smelling the food. At one time, we were almost allergic to the top 8 and then some....... I know it is hard but your son is young and eggs are relatively easy so replace in foods. You give him more of a chance by waiting until his number hits 0 or at least until he is a bit older. I know a pain but you can do it. Let us know what you decide. Good luck and always remember... go with what you feel is right for your child, the allergist doesn't always know better.

Do you usually trust this doctor? How did you discover the egg allergy - had he had an anaphylactic reaction?

We've never gotten to the point to challenging egg (my son is now 18) so don't know what to tell you. But my son has reacted to egg before. If we were just going by test scores and challenging in a doctor's office, we might have done it to hopefully safely make life easier.

I think we are going to wait it out. There is no reason that we should risk anything. I would rather do the challenge once the Rast and skin test show nothing. My husband says it is no different than what we have been doing! Thanks for the advice!

Jana R.-Hi My son has never reacted to egg before. He had eaten it before no problem. He would eat scrambled eggs, things that contain whole egg, egg whites and yolks. We found out after he got the hives from the peanut butter. Went to the allergist expecting to only see peanuts when the egg was a bigger wheal. We would even accidently feed stuff with egg from not checking the label of some stuff we already had in the pantry. Still no reaction. I think we will just skip the challenge for right now and hope for him to outgrow later. I do trust this allergist she is new to us since we just moved. She said there was an 80% chance of him tolerating, but I would feel better with 100% chance if someone could ever even say that.

I have a slightly differing view. Its well known that children who have egg allergy from a young age have a high chance of growing out of the allergy.

Our son for many years was totally unable to eat egg in any form. Skin hives ( for e.g) when standing in kitchen when I was frying a egg. When he was 7 after testing his doc decided we could have a egg challenge. He passed his cooked egg challenge, he failed the raw egg. This meant that any partially cooked egg ( like scambled egg) would cause a reaction. Simply being able to eat food with well cooked egg in ingredients meant that his diet was wider, more varied and higher in calories. Something that was important as he has always been underweight.

He has finally grown out of his raw egg allergy after a challenge this year. He is 10. We are still finding it an amazing thing to wittness our son eating a boiled egg or egg on toast. But its a food he enjoys. Its made a difference to his life, and being able to cross of a major allergen was fantastic. It also made things easier for me to arrange his food for a overnight school trip this year.

My basic point is that if a food challenge is conducted safely in hospital, its worth condsidering the long term potenital benifits on quality of life. Compared to the possibilty that your child may be avoiding a food when he is not allergic.

Certainly I agree with the idea of getting a skin prick test first. Then go over the risks and benifits of a food challenge with your doc. However having been through three challenges over the years I can say that although stressful and worrying , the long term advantages were worth it.

we have already been told that the peanut and bean allergies will be life long. he has many other allergies. If there is any chance that our son will grow out of any other allergies we would certanily consider food challenges in the future. We also plan to book testing for our son when he is going to be old enough to leave home and support himself. At that stage he will be able to see at what level he may be allergic, and ask the doc any questions. This will have more impact than us as his parents.

We just returned from an egg challenge...did not pass. DD,9, has always avoided egg (except for challenges). Her CAP-RAST was 0.8 three years ago so we did a challenge. After eating almost a whole egg then, she developed abdominal pain and mild nausea, no other symptoms, and that was considered a positive test. We continued to avoid egg. One year ago her level was around 2.5, too high for a challenge. Last week her level was 1.41 and we did the challenge today. After about half an egg she developed abdominal pain and nausea, then itchy eyes, nasal congestion and sneezing (no lower respiratory or skin symptoms). The GI symptoms improved within 10-15 minutes after oral Benadryl. The nasal symptoms persist after almost four hours, but are improving. The allergist thinks there is still about an 80% chance she will eventually outgrow, and if she doesn't entirely outgrow, as an adult she is likely to be able to tolerate small amounts of egg in baked goods but may never be able to eat an omelette.

Josh's Mom, If he was eating all of these things before then he's probably not allergic. The fact that he tested positive to egg when you were having him tested for peanut allergy means that it was a false positive (egg). At my son's last RAST test this year, they accidently tested him for sesame (even though he's been eating sesame all along without problems). Anyway, it came back positive. Dr Wood said we should ignore it since he eats it all the time. I'm surprised that your allergist made you avoid egg even though he'd tolerated it fine prior to testing. Technically, you are already giving it to him in baked goods anyhow. IMO, I would go ahead and have the challenge to put your mind at ease.

I'm not sure what you should do, but I'll tell you our situation. My dd ate a tsp. of scrambled egg at 9 months (ped had said to give her eggs, I knew nothing of food allergies). She vomited for about 4 hours. I still didn't think allergy, just that she was still too young (duh).

Ped said to wait a week and try again. Mother's instinct told me not to, and I waited until about 18 months or so to try again. She never had any other adverse reactions to eggs.

After her peanut reaction (hives above lip) we saw an allergist for skin testing (shortly after turning 2). We also expected only to see one reaction (she was tested for about 30 items). Her egg wheal was 6mm and her peanut was 5mm. The allergist did a CAP RAST for the egg the same day. It came back 1.61, and he recommended a challenge.

I had to cook very runny eggs and take to his office. They did it this way so when they heated them the protein wouldn't be diminished. After 4 hours of eating increasing amounts of egg with no reaction she was declared allergy free (except for PA). She had apparently outgrown the allergy but was still testing positive. She's never had a problem with eggs since that first reaction.

I guess if you trust the allergist, I'd go for the challenge, especially if he hasn't reacted to eggs. Since egg is commonly outgrown, I'd just ask the doctor if he failed the challenge would that exposure have a huge impact on his chances to outgrow it in the future. Good luck with your decision. Let us know what happens.

"...Everyone I know whose child is allergic can eat things with eggs in it just not straight eggs."

Hi there -- you seem to have already made your decision, but I just wanted to let you know that it is possible to be allergic to egg in any form! My dd cannot eat any "straight" egg (like fried or omelette), nor can she eat pancakes, waffles, ravioli, or anything else cooked with egg. She even had a ana rxn to pasta made on shared equip with egg!

Ditto here. DD is unable to even be in a restaurant which is serving breakfast.

She breaks out in hives from the egg aerosols, and has even had more serious rxns.

She also knows when something shares a line with eggs. Even if the manufacturer is adamant that it can't be XC, eventually I find out that it shares a line.

I have a call in with the allergist so I can talk to her about it. He has never reacted to eggs and he is not allergic to egg yolks. So I will post what she says. Thanks for all the information. I hope we make the right choice!
