I have read through alot of the threads and have noticed that alot of you with PA children have another child nonPA that is Ahsmatic! Is this just a coincidence?
My eldest daughter 5 is PA and her sister who is 2 is ahsmatic. I'm not sure though about being PA she is going to be tested soon. I was just wondering if ther is any link to this situation? Well take care!! [img]http://uumor.pair.com/nutalle2/peanutallergy/biggrin.gif[/img]

Well, my oldest dd age 11, not PA has had asthma since about age 2 and suffers from no food allergies at all. My middle dd age 5 had no asthma and no food allergies. Wade is 2 and has asthma and food allergies. I'm not sure if they are all related because I look at my middle daughter and she has nothing? Don't know if this helps.
Regards,
Katiee (Wade's mom)

Hi, there is some research into genetic links to this disease and the mapping the human genome project could shed more light. Apparently the tendency to food allergy, eczema and asthma are carried on the same gene. It is for this reason that after doing a family medical history when I was first thinking of becoming pregnant that my doctor recommended that I absolutely avoid nuts and peanuts while pregnant. I did so but still ended up with a son who is peanut and tree nut allergic and tends to asthma with upper respiratory infections.

MomLyttle, I had started another thread, under Main Discussion about PA children that were also asthmatic or had other medical "conditions". I had read that if your PA child was asthmatic, an anaphylactic reaction was even more dangerous for them. And, from the response I got to that thread, it looks as though a lot of us have PA children that have asthma.
Now, my non-PA daughter, out of the two children, she is on a preventative medication for asthma (Flovent) based on one viral infection she had and a persistent night cough during that infection. Now, I'm not even clear if she really needs the preventative medication or not. She has no allergies whatsoever (well, she tested positive for milk, but this is a child that drinks milk like it's going out of style!).
It is my PA son that seems hardest hit with things. He has had two actual asthma attacks, he has ended up in the hospital due to dehydration from the stomach flu. He has environmental allergies that I control with Claritin. He is down to two inhalers, from three for his asthma.
Now, he is in school, so of course, he is the one that catches all of the colds first, but he always catches them and he always has them the longest. Again, it seems to be my PA son that is hit hardest health-wise.
What I've been attempting to figure out, through a few recent threads, is where PA falls into the mix in all of this. He's a picky eater and very slender for his age.
And even after all of the wonderful responses I've had, I still can't figure it out.
I do know that he is very similar to me as far as allergies, etc. But, he is also built very much like his father. My daughter seems to be more like her father as far as allergies etc. and built like me. I'm not clear that PA plays a part in it at all, but I do know that it certainly opened up some interesting discussion. Picky eating was the only thing that seemed related, out of all of the "complaints" I have about my son, directly to PA. Otherwise, I'd have to say it was genetic in nature and what kid inherited what predisposition from one of two parents.
Also, please keep in mind that you don't know whether your younger daughter is PA or not.
I am certainly not wishing that she is PA. But, you may actually have an asthmatic PA child like a lot of us do here. This, again, is a wonderful discussion thread, MomLyttle.
I like thrashing these things around, and often times it seems like I'm trying to blame PA for this or that when I'm really simply trying to open what I hope may be interesting discussions. You've done that with this one.
Best wishes! [img]http://uumor.pair.com/nutalle2/peanutallergy/smile.gif[/img]

My older non-PA son is asthmatic - no food allergies now, but he had a whole bunch which he outgrew by age 3. My PA son is also asthmatic. They have different triggers, though. They also both had wicked eczema when younger.
While nobody else has the big time anaphylaxis problem that my PA son has, we are an extremely allergic family - pollens, fruits, veggies, animals, etc., so I guess it comes as no surprise. [img]http://uumor.pair.com/nutalle2/peanutallergy/confused.gif[/img]

I think there is definately a link with allergies. When I took my son to the allergist and was filling out the family history survey it hit me that we have alot of allergenic people in our family from hayfever, asthma to penicillin allergies and PA. This is including sisters bothers, aunts, uncles, cousins and grandparents.
Out of 19 family members 8 are allergic to penicillin and 3 are PA. 9 are asthmatic.

When I had my fourth child I was very concerned that she would have allergies like her brother. However it was easy to see that she displayed none of the early signs of allergy, that William, with hindsight clearly did.
Emily did not develop eczema , had a good sleep pattern, and gained weight well. Allergic infants often display these signs before the age of three months. Unfortunatly Emily did have severe colic, ( another western disease , like allergy) her crying spells lasted for hours, one day 11 hrs, a osteopath sorted her out!!!!!
Emily has had tree nuts in chocolate bars,but has not, at the age of four eaten peanuts. I dought if she is allergic, the latest advice seams to be wait until the child is 7 , and its easy to avoid peanuts until that time.
Out of my four children, only one has multiple allergies, the other children had mild hayfever before the age of five, 2 of them had v. mild eczema as well, that too disappeared at five years.
good luck .

This is a great question! I have three kids. The oldest is my step-son, who is not PA. My son is the middle child (PA) (but a LOT taller than my step-son) and my new husband and I have a daughter together. I found out about my son's PA 1.5 years ago after battling what we thought was asthma for 5 full years and it kept getting worse and more uncontrollable.
I didn't know my son was PA while I was pregnant with my daughter, but did find out before she was eating solids and vowed not to introduce her to peanuts or peanut products until she was at LEAST three. In all ways, she is a very different child. She has never had asthma, but she has had the occasional rash. They both slept through the night from about 4 months old on and were/are excellent babies.
Anyway, my daughter was given peanut butter crackers by my husband and the doctor on a recent week long stay in the hospital (badly infected lymph nodes). She got a localized facial rash, whose origin I thought might have been from the new antibiotic they were giving her.
Later, when I was considering eating some peanuts my mom had brought me while Lira was in the hospital (my son was at his Dad's, and I can't help it... I love peanuts, evil little things!), my husband said, "Go ahead. Lira had some in the hospital and didn't react." I gave her two little peanuts, and she chewed them up, said loudly "NUMMY" and started to scream for more (before she swallowed) and I said, "No more, chew what you have" and so she screamed and the peanuts came out and dribbled down her chin. Within one minute the skin on her face where she dribbled began to swell and turn angry red! I lifted her up, said to my husband "Looks like she's allergic to peanuts! Get the Benadryl!" and rushed her upstairs to the bathtub to wash all the peanut ick off of us both. The rash went away in about 10 minutes from the time I got her in the tub and the Benadryl got in her system.
It wasn't exactly the way I PLANNED to go about finding out if she was allergic. I had PLANNED to wait until she was three and then do a spot test on her lower middle back with some peanut butter (with an EpiPen handy!). But, things don't always work out how you intend.
I took my daughter to the allergist a couple weeks ago and had her tested for peanuts (and a few other things, all negative) and she was 4++ on the peanuts. Using hindsight, I'd say... if you have a child with PA and younger siblings, I don't see how it could HARM anybody for you to take them in for the test! It will ease your mind and possibly save your childs life.
I would hate to burden another person with the guilt and horror of not knowing how to treat an anaphylactic situation concerning one of my possibly PA children, when it was a simple test I could have had done any time! Knowing that one of your children is PA isn't a guarantee that any of your other children will be, but for the sake of peace of mind, finding out is the best course you can go.
Good luck!

I have a 2 1/2 year old with Peanut & Tree Nut allergy and a baby on the way. I plan to treat the baby as peanut & tree nut allergic until he/she is old enough to be tested by our allergist.
I do want to comment that Jamie had no "symptoms" of being peanut allergic until we gave her a taste of peanut butter at 18 months. No one told us to avoid peanut products until 3. They just said not to feed her peanuts because of the choking hazard. She was a very healthy baby. No eczema at all. No signs until her lip swelled up & she had a rash after eating a small amount of peanut butter.
Keeping the new baby peanut & tree nut free will be pretty easy because our house is peanut & tree nut free.
Stay safe & don't take any chances with your other children until you know for sure they are not PA or TNA.

I am not sure if I am the one to answer this...but this is what we've done. I guess the difference is that your 3.5yr old has no know allergies, my younger siblings did, so they were of course tested for those and the foods their older brother was allergic to. I think(if I were you) I'd talk with the allergist right before entering kindergarten to discuss testing and maybe a challenge to any of the foods your are worried about(like peanuts). My almost 4yr old is going to be re-tested and hopefully challenged(so far his pn/tn has been negative, but he's never had any either) but I'd like to know for sure before Kindergarten(for 504 purposes). When he enters preschool next year, I just use the phrase "we are avoiding all pn and tn because of his brother's life threatening allergy"...I spoke with the director, they are fine with that idea.
Anyways, not sure if anyone will agree with me or not, but I would want to know *for sure* before entering Kindergarten....so I think testing beofre is a good idea. I hope it all stays negative for you, good luck!!!

We had our 2.5 year old tested a few months ago for all peanuts and tree nuts due to the fact that our 5 year old is allergic to both.
My 2 yr old tested neg to all, however, I have not gotten up the guts to try anything on him yet. I may ask the dr at my older son's next appt if I can do it in the office.
My husband and I wanted to know either way. Regardless of the results, our home has stayed peanut/tree nut-free. It just makes it slightly easier on play dates, b-day parties, etc. when it's he and I alone and not with our older son.

Does a skin prick test show positive if it's a first exposure?

I just had my 4 year old in the allergist this week for testing. His 7 year old brother is PA.
It came back negative. He has never been exposed to peanuts or tree nuts. He is not allergic to anything else and does not have any seasonal or pet allergies.
The allergist did suggest when he will be going into the first grade and eating in the lunchroom that we do a food challenge there so they can moniter him.
She also told me they are now recommending that you wait until your child is 4 to introduce them to nuts or peanuts. I guess this will be something new they will be announcing.
I would wait on giving nuts or peanuts, just my opinion.

We had our 2 1/2 YO DS tested 2 months ago- his sister is PA, TNA, soy, and egg. He was negative for all however he has never been exposed to Peanuts or any tree nuts because of her allergies. So we will be restesting him in August (when he turns 3) and right before he is to enter preschool. Our allergist said that if he passes the SPT then he will be taste challenged in the office to clear him before school starts.
I really wanted him tested for my own piece of mind before he started preschool. So now we are just waiting to do it again.

I thought that you had to be exposed first for a test to be positive...I remember asking my allergist to test him for foods because I was worried...he would not do spt because it could expose him. He was only 3 and we were testing environmental allergies.
I may be wrong, but I thought it was the same as for a bee sting. Most people do not react the first time they are stung. It is the second time that a reaction will occur?

I do think having a reaction the very first time exposed is rare(but I could be wrong as well). I have been testing my almost 4yr old every year, even though he's never eaten it. I am hoping that *little* exposure from the scratch test will be enough for his body to decide if he is or isn't allergic once we do the challenge. BUT...like my pa son, he had eaten pb crackers many times prior(like over a 3-6mth period) before he had a reaction) so I guess you never can be too sure, but you can try to figure out what you can ahead of time....

hmmm! I thought the same thing. First exposure you don't react. But my son did react the first time he was stung. He was probably bit before his first reaction to a bite -- but I'm sure I would have known if he had been stung previously because it really hurt. Odd.

This is why I am unsure...my 1yr old was given a strawberry newton, for the first time, and she started screaming and pulling at her tongue. She also got some small bumps around her mouth(I gave Benadryl and it stopped after 20 min)....but that was the first time she'd had strawberry(she usually eats just baby food)....we're avoiding for now!!

When you say that you are avoiding allergens with the younger child, to what extent are you going? Are you feeding nothing that's made on shared equipment, avoiding x-contamination possibilities in restaurants, etc.? I ask this because, if she's never had any exposure to the allergens, my understanding is that she definitely will be negative. It takes at least two exposures to trigger an allergic reaction (it can be many more than two exposures before the allergy develops). If you've always followed as strict precautions to avoid the potential allergens as if she actually had the allergy, I don't see how the testing could be a valid test whether she's actually allergic because she hasn't had that first exposure.

My 7 year old has PA, and I brought her younger brother in at 18 months. We'll get him checked annually--He's 2 1/2, so far, no allergies. It can't hurt to test them this young, my daughter had the allergy at that age. You just may get a false negative, which is why you should keep re-testing until they're about 5. If he does test positive, I would want to know sooner rather than later.

My oldest, 6, is ingested, contact and airborne to peanuts with a host of other FA. My 3 year old is only allergic to weeds. We have had her tested twice. My feeling for getting the tests are that she is now participating in play groups and we have left her with a sitter when we have taken DD6 to plays and the like. Although our sitter is VERY aware of the possibilities, I feel better leaving her in cell phones off situations. DD3 still avoids anything that has caused her sister to have anaphalactic reactions (99.999999% avoidance). We are also going to do an ingestion challenge at the Doctor's office before she starts school. She will still never take or eat a PBJ, but the oops factor will not be the same as with her sister.
I will say it was so strange the first time I left DD3 with just a snack bag and a change of cloths--no epi, no benedryl... It almost felt 'normal'

Our allergist told us that the whole "had to have been exposed first for it to show a positive" theory was untrue. I am not saying whether he is 100% correct, but he was adamant that a SPT was not necessary when testing our younger son for FA. He had an immunocap and tested negative. Also, my PA son absolutely reacted to his very *first* exposure to pb, he was only 11 months and had never been exposed before.
My friend's child had an anaphylactic reaction to her very first taste of pb, again that time it was her very first exposure.
The idea that if one sibling is allergic the other one will be is not accurate (IMO) - they have a higher likelihood, yes, but of all the PA kids I know in our school community, they are the only one in their families with the allergy, none of the siblings are PA.
