Testing younger siblings with no exposure?

Will it show a PA?

Have you done it and what were the results?

What do they eat in preschool situations?

I am trying to figure out if I can let ds just have *whatever* in preschool(it is a nut free school), but we are avoiding peanuts/tree nuts until age five. I feel suspicious of sensetivity due to ? contact/airborne eye reactions at our farmstand with lots of birdseed/nuts at registers. The checkout clerks(moms) have twice asked if he is okay. So it is not my imagination. He gets an itchy eye at times(my dd's most pronounced reaction at that age).

I guess if that has triggered something, he would test positive, right? I am thinking of having him tested, but really doubting the results if he were negative at just 2.9. I have enrolled him in preschool and am wanting an epipen for him. Have any of you had epi prescriptions for younger siblings at school "just in case?" The preschool would be very cool with that, but not sure our docs would.

I had raised an old thread, but it did not get any response, so starting this. becca

PA/TNA DD is almost 10. We treat her younger sister the same. Last year sister (4yrs) had a RAST that tested just for peanuts and it was negative. However, Dr. said this could be because she has not been exposed and therefore has not had the opportunity to form the antigens. However, I was glad to hear the test was negative and we still avoid peanuts and tree nuts. She is now 5 and will start kindergarten this fall. This summer I will take her for further testing- so if she is allergic then she will have the epipen for school etc. And if she isn't then I don't have that to worry about w/ her. I will also have my older DD tested, since she was tested at 6 and will be 10 soon.

On Feb 28, 2006

But if she has never been exposed, as before with her test, what makes you secure now, if her test is neg. again? Just wondering. I am worried he will test neg. due to lack of exposure, but could react, and not have epipens at school. becca

On Feb 28, 2006

For the test this summer- if the blood work is negative I'll request a SPT. If that is negative then I'll request a challenge in the office. She had an accidental minor exposure to peanut butter in icing on a birthday party cupcake when she was about 18mths. She just had a small taste- if anything at all- before I took it away and she was fine. She has been around peanut butter and has eaten some nuts successfully. She already tells people she's allergic to peanuts. I would just like to know for sure.

On Feb 28, 2006

I can't say for sure w/r to PA specifically, but I do know what our experience was with TN. All the initial TN tests (RAST and SPT) were negative. So our allergist told us it was fine. We argued this point by pointing out that she had been diagnosed as PA via anaphylaxis so young that she really COULD be totally unexposed to TN. He didn't think we could have avoided trace exposure that successfully. So we gave her filberts very very cautiously. She liked them and ate them fairly sparingly over a period of about six months. We then gave her a few almonds to try. She ate about two at a time over a period of four or five days when we noticed eczema flaring after she ate them. Duly noted. Filberts around the same time resulted in a few hives on her back. Also duly noted. We tried these nuts only because we knew we had a safe uncontaminated source of them (living here in filbert-ville).

Retesting showed she is now (drum roll please) ALLERGIC to them both.

So my advice is that if your child tests negative, insist upon a challenge, and then retest to make sure.

Allergist listened to us when we wanted a test for pistachio. Thank goodness. That was the skin test that got used for show and tell. The sensitiztion was only having a nut shell in her mouth at about 9-10 months old. (shudder)

So if anyone tells you that you can't possibly have really prevented all exposure, DON'T LISTEN if you know you have been that careful.

Hmmm. We have been a nut-free home and dealing with dd's PA for 5 years. So, we have been that careful with him, as he is only 2!

I had the worst dream that he had an anaphylactic reaction, just before I woke today! It was weird because I had been given unsafe chocolate with nuts in it(in the dream) and it was in one of those bags that opened poorly, and it kept ripping a bit more as I scrambled to pick up pieces of the candy before ds did! On and on. I finally get it all cleaned up, and he wanders out of my closet with a PB cup! I do not have those in my closet, IRL, before you think I am a closet eater! Anyway, he has nibbled just edges off the chocolate and I am trying to get it away from him, and he is dodging me. I get it. Watch him, scrambling to clean him up. He gets horse. Dh is in bathroom, just going in to shower. I am alone to run *downstairs for epi*, and I only have expired Jrs. I have kept around for just such an emergency. He is limp in my arms. I could cry tying this(or throw up). Then, it is a dream, so I actually seem to have given him 1/2 of an adult epi(maybe all I could grab quickly enough). He is still for the longest time. Then cracks a smile at me, and says his tummy hurst!

How vivid is that??? I have never had such a dream for dd, my known allergic child. I think I fear the unknown more than what I do know. becca

On Mar 1, 2006

I've asked Dr. Wood this question a million times. I am so worried about my 2 younger boys since the 2 older girls are so allergic. Basically, he said everyone gets some form of exposure.. breast milk, airborne, cross contamination. He recommends waiting till they are closer to age 4 before testing. He told me if they test negative with no symptoms to say otherwise I should feel comfortable they are negative. Jackson has tested negative twice to peanuts and nuts. He's never eaten one but just recently I've let him have something with a warning label of "may contain." He was totally fine. The preschool still doesn't give him anything and when I registered him for kindergarten I told them I didn't want them to give him anything with peanuts or nuts either.. a dietary restriction as opposed to an allergy. I'd prefer he not have anything he can bring into the house and contaminate.

I will let both boys eat birthday cakes and stuff from a bakery which I won't with the girls. SO I feel they are getting some form of exposure and I trust the tests to be accurate.

On Mar 1, 2006

becca, don't you hate those dreams that scare you half to death. The worst part is they linger and make you feel uneasy afterwards too.

Did you nurse your son? If so did you eat any may contains while doing so or while pregnant?

My son was tested at about 16 or 17 months and had a 4+ skin test. He had no known exposure. The only exposure must have been while I was pregnant or nursing.

I think it is worth taking him to the allergist, getting him tested and telling them of your fears.

Good luck.

On Mar 1, 2006

I definately might have eaten may contains, but no known nuts. I did also get a walnut in an ice cream from a stand, while pregnant. Just for anyone who considers risking hard scoop ice cream! So, I suppose there is a chance there has been some mild trace exposure. And, with the itchy eye thing at the farmstand, it might be a contact exposure. If it is enough to make his eye itch and a bit puffy, then it would test, even if low. I also wondered of he got a similar contact eye irritation at a friend's house(where dd has always been fine). I know he, they, consume alot of nuts. She has warned me and watches dd very closely, changes her son's clothes sometimes, in order to play with dd.

So, I guess I have enough suspicion for testing. Part of it is I want ds to have a perfectly regular preschool experience if it is safe for him to do so! It is a peanut and nut free school, but the risk is in birthday and party stuff, unknown may contain type foods. They do not entirely get that there.

He has a perpetual dry rashy deal around his mouth and even now has a funny spot under one eye after chowing Thomas bagels for two days. I actually question sesame, which can require more vigilance, with crackers, bread... alot of mystery spots and mild skin dots here and there.

I guess I have enough to go for testing. Maybe even just a first pass on bloodwork with the ped. He is great and we can pop in anytime. I wait months for the allergist. Plus, I do not really want spt at this time, so the ped can do the bloodwork anyway. Ds would never cooperate sitting for 15-20 mins with serums on his forearms! I can't ever imagine him siiting still that long anyway! Thanks for all the input.

I really want to know, but I don't, and I am sure you all understand what I mean!

I will call the allergist for advice too. Maybe he will recommend what to check before knowing if he needs to see ds. It is all on my mind because I will have to schedule dd's annual allergist appt. soon, and decicing if we should just bring both children. becca

In our case the other sibling is a twin instead of younger. But we ran the RAST last year, and it did show up as negative. Like the rest of you, we had never allowed him to eat peanuts, so we are not 100% convinced. So we now allow him to eat "may contains" occasionally. But we are going to give him a scratch test & a food challenge this coming summer when we do our yearly allergist visit for the PA son. This was recommended by the allergist, and we gladly agreed.

So far, both sons have always been in the same class room - both pre-school and now kindergarten, and I have told the teachers the situation, and for them not to hesitate to give the non-PA son the Epi if he seemed to be reacting to anything.

------------------ Sherlyn Mom to 6 year old twins Ben & Mike - one PA & the other not. Stay Informed And Peanut Free!

On Mar 1, 2006

becca, as far as what to test for, my allergist recommended at such a young age that they test for egg, wheat, milk, and peanut. I would also add in sesame since you have suspicions. I have to get that one done for my son as well.

On Mar 1, 2006

becca, it's actually reassuring to me to hear you're in the same boat. I haven't ever purposely fed my 3YO peanut anything, but once she had some suspicious hives on her ears with something that could have been cross-contaminated. So I'm trying to decide if I should put her through the skin testing, which is how my PA DD's allergist tests. I think we'll do it this summer when she turns 4 unless she has further suspicious symptoms. I want to know and I don't - I'm with you there.

On Mar 1, 2006

Right, I mean, as long as they are always under our watch, we have epis for the older child anyway. But he really needs a Jr. and ours are now almost 3 months expired. I just need the security of him having epi, more than anything. Dd now has full dose, so I have to deal with it now.

Does anyone have a doctor prescribe just in case, because of the family hsitory, for the preschool age? As Sherlyn said, she is fortunate her twins are together in the event of an emergency. It is reassuring to have it there. Seems all schools should have it as a first aid item, regardless. The unkown allergy is more dangerous than the known for anyone. becca

On Mar 1, 2006

Becca, we're in a similar situation. My 3yo DD will be in preschool when she's 4yo, but we keep a PN and TN free home because of her older brother. I know she's had a couple of "may contains" items (not from me, but from other well-meaning family members [img]http://uumor.pair.com/nutalle2/peanutallergy/rolleyes.gif[/img], and one cookie that actually had walnuts. I suspect that she is not allergic, but I'd feel more comfortable with test results prior to sending her to preschool. She's never had eczema the way DS did as a baby and toddler, and there isn't even a hint of asthma as yet. The preschool DS went to is nut-free anyway, but they do allow "may contains" for snacks. We'll probably talk to the allergist about it one of these days when we see him with DS.

Good luck with your decision!

How timely to find this thread!

Our DS is 7 & PA (anaphylaxis at 11 months)& with still-questionable TNAs.

Our DD is 4 1/2 & has tested negative (skin prick) to peanut, as well as other food allergens. We know she was exposed to may contains and tree nuts when she breastfed (for 2 years).

We currently homeschool, but hope to have kids mainstreamed into a public or private school this coming school year -- DS will be in 2nd grade, and DD will either be in K or pre-K, depending on age cutoff.

We plan to have included into DS's 504 some restrictions regarding handling of his sister & restrictions for her exposure as a means of protecting him. There will also be some sort of other written agreement for her teacher/classroom so everyone is on the same page.

As to Epi-pens, our DS has a prescription for *both* Jr & regular Epi-pens. He now weighs 59 lbs (weighed 51 lbs when Rx was written). Current pediatrician was OK with reg Epi-pens, but a second doc felt he was borderline on weight & wanted Jrs. We gave up arguing & realized it would mean we then would also have Jrs to use on DD (weighs 39 lbs) if she were to have anaphylactic reaction to something. So, we always carry 2 of each size & additional for trips. But I'm betting the school won't allow the Jrs on the property for DD unless doctor writes order for it.

Anyone have specifics for sibling written into PA child's 504??

We've got the same situation here too. My oldest has PA and my youngest is about to enter pre-school - he' s never has a taste of peanuts. Last time I asked about testing my youngest, I was told the same thing about the antibodies - no ecposure = no antibodies, so there's really nothing to test for.

He's shown no signs of allergies (knock on wood) - with my oldest, I had suspicions of allergies from the time he was born.

I've enrolled him in pre-school this fall, and have the same issues with the snacks. I do let him eat may contains, and he's never had any issues. It was a hard decision, but I've decided to let him eat whats brought into the classroom, provided there are no actual nuts or peanuts in what he's eating.

On Mar 6, 2006

Hmmm, Becca, I think I'd probably have him tested, both skin and RAST. After you get those results in, then you can figure out what to do next.

I'll just relay our history too. Like others, confusing and not concrete. MFA ds was exposed to peanut butter while I was pregnant, and perhaps with traces around the house after he was born. I was unable to nurse.

I do remember, however, being very careful to wash up after eating it once the kids were born. Odd thing to remember considering how much else I've forgotten...mother's intuition I guess.

Anyway, he was diagnosed with PA through testing only, no known ingestion. Since diagnosis, he's had 2 reactions that I'm just about positive I've traced back to peanut residue.

MFA ds has had eczema since 3 mos. old. His twin doesn't have eczema. But he does still have reflux and has those allergic shiners under his eyes. We had skin testing done around time of brothers' diagnosis, negative. We just had comprehensive bloodwork done through a GI , all negative.

But the reflux and shiners still make me wonder, and I'm making an appt with the allergist for another skin test.

They are currently enrolled in preschool together which has an extremely controlled food environment. But come Kindergarten, it will be totally different.

I would follow your instincts, sorry about the scary dream, how vivid! The problem with testing is we all know it's not completely accurate...but if it's positive, then requesting an epipen won't be a problem. If it's negative, then what to do? Meg

I just had our 3.5 year old tested for peanut - skin testing. His almost 6 yo brother is PA (RAST 82). I originally didn't want to do the skin testing but our allergist changed my mind. I felt comfortable doing it and the great news was that he tested negative to peanut, almond, cat, dog and dust mites. The only spot to react was the histamine spot. We discussed his only chance of exposure would have be in the womb before I found out about our 2nd son's PA when I was 5 months pregnant with our 3rd. But the allergist said it would show up in his skin if he was allergic.

He also said "don't rush out and give him a peanut butter sandwich though" (we have a peanut-free house) but you don't have to worry about the cupcake he might have in preschool next year. He also said that although some people do "grow into" allergies usually that is not the case. So I don't plan to give our littlest anything peanut but I have let him have things that I would never give to my PA son - when he's out with Daddy, not here in our home.

I wish you the best with your little one - hoping for negative testing!

On Mar 6, 2006

My non pa son(turning 6 next month) had a rast test at 3yrs old and it was negative. I do not let him eat any peanut or tree nut products. I do however let him and my dd who is 3 eat cakes at parties and thinsg like that. I do not have may conatins or peanut tree nut products in my house. Our school is does not serve things with nuts in them or peanuts. He is allowed to partipate in parties at school. He also had reflux and has bad allergic shiners, although last year he tested neagtive to enviromental allergens(well the major ones they test for) this year he has gotten worse and is now starting zrytec. I need to take him back to get retested.

My dd is a different matter. I too had a nightmare about her, inthe dream I was in my grandmothers kitchen and we were having a wedding for my pa son, who in the dream was still 8 and no bride was in sight. Anyway I baked him his wedding cake and put it in front of him. He looked at me and said you know I am going to eat this and picked up a peanut M&M and started biting it, next thing i know it's my 3 yr old who is limp in my arms. i called 911 and stood outside on a busy street waiting for an ambulance that just never came, firetrucks, police cars ect kept passing me by,no one stopped, it was such a horribel dream , oh and my father tol dme that i didnt speak to the 911 operator correctly, i mean what is that about??

On Mar 6, 2006

We're dealing with this now. A few years ago we had our two younger kids cap-rast tested. After they drew blood, the dr sat down with us and said that they can't actually be allergic to something they've never been exposed to, so even if the test came back negative (which they did) we should still avoid since they have a higher than usual risk of having or developing a food allergy. Gee thanks Doc, after taking blood from my 3 yo and 5 yo you tell me this. It was a big waste of time, pain and money. Now we're thinking of taking them to another allergist and having skin tests done, because I'm tired of not being comfortable with putting them in activities like scouts and such not knowing for sure if they're allergic or not.

Before we knew that my now 3 year old was mfa, the allergist gave me an epi for her since her sister is PA. Makes one feel so much better...just in case. Of course now we know we MAY need to use it. She has at 1 time or another been allergic to soy,corn,rice,eggs,barley,oats,rye,amarnath,quinoa,blueberry,some melon... and we stay away from shellfish and fish and of course no peanuts or nuts. Oh ya, we recently added dairy which lead to 2 trips to the ER in 12 hours. I woould also say that due to the history of the PA sibling, one never knows if an unknown allergy could "pop up" such as our recent milk allergy. Out of the blue, with all neg RAST tests before and still testing neg. I have read many times, that when you have an allergic tendency allergies can pop up anytime. Better safe than sorry. I think you know all this but thought I would post anyway. MY mfa has gotten back so many foods so it was a shocker with the milk... we didn't have to use the epi but I felt much better knowing I had it for her. I can't and can imagine that your allergist wouldn't agree to an epi for your child. Some allergists are so open and others like to rule the roost. As I am sure you know. My mfa tests neg to many of the foods she is allergic to but then can't eat them. Voila, must have had them through breast milk. I am in the same neg RASt results for PA/TN for her but I don't think she will be able to eat them so I am not testing her and just saying she is allergic although her teachers will know that we really do not know. Good luck

On Mar 6, 2006

My DD is almost 5 and has MFA. I was told to have my DS tested when he was 6 months. He was tested for all the major ones and came back positive for peanuts and soy, both mild. I am still paranoid, if he goes somewhere without DD the extra Epi goes with him. I did have a few may contains when pregnant with him, I was told that was okay(should not have listened). Now pregnant with #3 I will avoid all may contains. We will retest him before he goes to preschool.

On Mar 6, 2006

So, if your ds tested positive to peanuts, why doesn't he have his own epi RX?

I guess I just will book ds when I book dd for her annual allergist appt. Maybe dh can come and we can just do them both together. Might help for him to be with er for the testing, and waiting. Hmmm, then again.... they could get pretty silly or something if bored together, LOL. becca

On Mar 7, 2006

I know I've read that reacting severely to skin testing is a possibility, but we've been ok with it so far...my allergist wiped off the peanut protein "stick", and my ds still developed a wheal from it (not surprising I know)

But, this is scary.

I treated my youngest, now 6, as if he was PA until right before he started Kindergarten. That May I took him for a blood test for peanuts along with repeat blood tests for Ryan. My youngest's result to peanuts was negative. We then went in for a skin test. It was negative so at that point we did an oral challenge (in the office) with the most allergenic peanut product (which caused two severe reactions with Ryan) Ryan had consumed. My little guy had no problems with no reactions. He was definitely exposed through peanuts via breastmilk before we knew Ryan was PA, so at this point his negative result is correct.

I couldn't send him to school without knowing. It wouldn't make sense to me, nor the school, if I did. On one hand I have Ryan, severely allergic with an extensive 504 and lots of epipens at school. For me to say I don't think his brother is allergic and not have him tested but avoid peanuts would not make sense. I need to know--have to know so proper precautions can be taken with medicine available.

Our 8year old son is PA TN allergic and now has the adult Epi-pen. We have an almost 2 year old who at 1

On Feb 13, 2007

I just brought my 4YO DD in to my PA DD's allergist. My 4YO has had 2 suspicious hive incidents in her life, both after eating and not doing much else, but we haven't been able to figure out what caused them. They did do a basic food allergy RAST at her check-up last summer and everything came back negative, including peanut. We've fed her tiny amounts of peanut butter a few times with no reaction.

But I just haven't been feeling comfortable, so I went to the allergist for advice. He thinks it's unlikely she has any food allergies. He said we could do extensive testing, looking for a needle in a haystack, and we probably wouldn't find one. But if it made me feel better, we could test for tree nuts. I wanted to do that. So we did a blood test and we'll find out the results in the next week.

DD has really only been exposed to almonds on purpose (long ago) because we now have a nut-free house, so I really don't think we know her status with tree nuts, and one of her reactions was after a bakery cookie.

Do you think it's funny that an allergist would not be concerned about the sibling of a PA kid, who has had 2 mystery hive incidents herself and is allergic to penicillin (thus, has an allergic tendency, too)? Maybe not everyone thinks you should test just in case? He says (which is true) that you don't really know if someone has a food allergy unless they've had a food challenge of some sort.

I really got the impression that he thinks I'm worrying too much, but that a test for just tree nuts would be reasonable to calm my fears before DD starts school. It's funny, but he was one of the people to put the fear into me when we first went to him for my PA DD! But he would have suggested that I just feed the younger one nuts without testing her first; he just went along with me on the testing.

Also, any opinions on a persistent rash around her mouth? It comes and goes for weeks or months at a time. He and a pediatrician previously believed it was just irritation or dryness.

On Feb 13, 2007

I do not remember the details on this because my daughter is almost eight now, but I do know our pediatric allergist skin tested her between the ages of 1 and 2 for milk allergy. It runs in our family (my son is 3rd generation), so it was good to rule out.

I believe she was also tested for peanut around 3 or 4. We had no reason to think she was allergic and she's not.

We've gotten a lot more relaxed about her in general because she does not appear to have any food allergies, but I did have a moment of anxiety at a party the other night when she ate a shrimp. This is a kid who generally doesn't eat anything unless it's white in color, so I was totally surprised she tried one! No problem.

Regarding Epi-Pens...interestingly enough, they are formulated on the basis of body *surface area*, not weight. The weight guidelines just approximate this surface area. My son is very tiny weight-wise, so we had whole conversations on this topic with the pediatric allergist and he said there isn't a huge difference between an Epi and an Epi Jr. He prescribed an adult Epi for my son, even though he wasn't over the weight recommendation because he was tall enough for it.

And no, a doctor is not going to give you an Epi-Pen unless there's evidence of a clinical allergy. Epi-Pens can cause heart arrythymias (and death in rare cases), so there is some potential liability in prescribing them without a reason.

Sadly, I read a case history once where the person was having a panic attack, treated themselves with multiple Epi-Pens (which obviously didn't help the panic at all), and ended up dying from the epinephrine.

On Feb 13, 2007

My younger DS has RAST tested negative twice for pb. The doctor says go ahead and feed him pb but I haven't had the courage yet. He is in a peanut/tree nut free preschool so I haven't really worried about it. Since he was going to enter a non peanut free school this fall, I was planning on feeding him pb this spring, at my mother's house because she's right up the street from the hospital, on a weekday while older DS is at school. I wound up putting DS in another year of preschool so I'm debating if I should bother this year or push it off another year. Since I have my younger DS with me a lot when my older DS is in school, I allow younger DS to eat "may contains" when his brother isn't around. Funny about your dream, Becca, I had a dream last night that I finally got up the courage to feed my younger DS pb and I realized I had lost my purse with the EpiPen in it.

On Feb 13, 2007

my son is the oldest, and when my daughter turned 4 I had her tested be4 putting her in preschool. unfortunately, she tested positive to both blood and skin. I really thought for sure she would not have it. [img]http://uumor.pair.com/nutalle2/peanutallergy/frown.gif[/img] She too has never had any exposure, but with both tests coming up positive, that's all I need to see. She also tested high like my son. I don't put my test numbers because everyone's are always so different. They both tested in severe category.

On Feb 13, 2007

I am in the same boat, I have 2 younger siblings but we went ahead and skin/blood tested them for peanuts, so far both are negative. I think if it continues, I will have a food challenge before they enter Kindergarten. They have both been exposed)(through breatsfeeding, I still ate pb), so I don't think it's a false negative...I'm just not ready and would never test them myself at home anyways(nor would they even be eating it, but would like to know for school). The same pair have positive skin/blood to eggs but I've never seen a reaction in either of them....we'll address that in a few years as well. Age 5 is a good goal.

But, like others suggested, if you are worried, do some further testing with the allergist and a possible food challenge right before entering school.

We have a 23 month old who is severely peanut & egg allergic. We also have a three month old baby. We are limiting exposure to main allergens with our second child (as we did our first) and are hopeful she does not also develop allergies. When is the earliest we can have a useful skin test done ... I read 18mos somewhere ... is that correct? NP.

I'm not positive, but we did get my daughter blood tested at 6 weeks. She reacted to milk and just wanted it confirmed before cutting everything out of our diet(plus it's good to have a confirmed positive on record, I know some will argue the importance of testing...I test). They did skin test her as well, just this winter, so right before age 1. That's when egg showed up, we also did blood work again to get the numbers of the egg and again the milk.

Under age 3 their immune system is still developing, so you may or may not get correct results, but if it is positive, it's usually a low number. At age 3 it all peeks and the numbers become very high, but their immune system is fully developed so you can start checking for environmental and seasonal then as well. After age 3, their test results tend to come back down a bit(level out so to say)....(this is how it was explained to me by the allergist, so of course I could be wrong).

Thanks ... that is consistent with what I read. I'll probably bring our youngest in to see the allergist once we start introducing solid food, with the understanding that things could change. Our oldest displayed egg allergy at 8 months and had a slight swelling reaction after eating a muffin that had a stray nut in it at 15 months. So there is no need to wait until three =) NP.

Hi. I just wanted to add that my dd's allergist tested her at one year. I have also talked to many other pa parents who tested at similiar and even younger ages. Unfortunately, her rast level is as high now as it was when she was one. This is almost eight years now since her first test.
