Hi

I have a question re exposing a younger sibling to peanut products. My son is 4 and had a reaction to touching peanut butter when he was 18 months. He touched peanut butter and then touched his face and his face promptly swelled up. Further ST showed a 7 mm reaction and his RAST was 67, so needless to say we are peanut free and carry an epipen.
I have an 11 month old that we just got tested with a RAST test and his test was negative. He does have eczema and I know that he has a higher chance to developing food allergies. My question is whether I should expose him to peanut products or get an oral challenge and if he tolerates peanuts then continue to feed him peanuts?

Let me tell you my reasoning. I had always heard about avoiding peanut products until age 3 but I went to an allergy talk recently and the allergist mentioned a study of Jewish kids in the UK. There was one group that had a high incidence of peanut allergy and another group that had no peanut allergies and the main difference was that the non allergic group were from Isreal and had been fed peanut snacks called bambas from when they were babies and therefore never seemed to develop allergies. Has anyone heard of this?

thanks

different genetics? pnuts weren't roasted? who knows. Besides it wasn't a study of people at higher risk was it? My 2nd ds was neg at 1 and 2 yrs as well. Then tested positive to walnuts and pnuts at 4 yrs w no known exposure. I suppose we just delayed the inevitable. But if you decide to try it you should get a skin test 1st. RAST can't be positive w/o prior exposures.

Hi Luv,
OK, 1st child--PA
2nd child-TNA
3rd child-both of the above(with no exposure to either before test)
2nd child tested neg to peanuts when she was tested, skin test, but did not have her tested for TNA. Well, found out the hard way, by ambulance that she was allergic. I never gave my 1st PA child any nuts(peanuts/tree nuts) after I found out that he was PA, but I was pregnant with our 3rd and was not with my PA son--so I had some cashews(Fried in canola oil-not peanut oil), so I gave some to my 2nd child. She went into anaphylaxis.
The only thing I find weird:
First Pregnancy----
Ate peanuts, peanutbutter, whatever when I was pregnant. I grew up on this. He ended up allergic.
Second Pregnancy----
Ate cashews--ALOT, and almonds because I was staying away from peanut products. This baby ends up allergic to cashews and almonds the worst, but all Tree nuts are off limits.
Third Pregnancy----
Ate NO NUTS at all!!! Third child ends up allergic to both.
I nursed all of them as well from 1yr-first child-------to 2.5 yrs third child. I don't know what to tell you.
I agree with the fact that the factors involved in the study were not clear. I mean, just saying a peanut or a food made of peanuts if not enough. The conditions have to be more closely related, like the predisposition to food allergies etc.. I would not give the nuts, I would never have it anywhere around my PA child at all. But that is just my opinion. Good Luck.

Correlation is not that same as causation. If I had fed DD "bambas" when she was a baby she would have reacted to it. She reacted to my breastmilk. Exposure/non-exposure is only part of why people develop food allergies. Genetics is another part. Food allergies are caused by the interplay of these and other as of yet unidentified factors. My feeling is that if you have one child with a known peanut allergy, the chances that one of your other children will have a peanut allergy are higher. Early exposure could lead to sensitization. Delay may prevent sensitization if the immune system is allowed to fully mature.
Also, the group that fed their kids "bambas" probably did not have any family members who were allergic to peanuts, right? So their kids were not predisposed to having peanut allergy. Yours are.

I wonder about this myself. My oldest son tested positive via SPT (and reacts to) a host of foods including peanuts and tree nuts. Given our history, I had my 4 mo old son tested this week and he was negative to everything on the "baby panel" (did show a slight reaction to carrot, but they doubt it will cause an issue). We will continue to have a nut free home for my oldest son, but worry about my youngest son when the time comes...
IF Connor continues to be negative and passes a food challenge in the office (or the parking lot of the ER if they don't feel its necessary), I will hopefully be able to send him to eat PB at my parents house (we hope they are moving up here next year) or at another relative close by. We have a few years to cross this bridge because I doubt I would let PB cross his lips until he is at least 4 or 5.

Hi Jennifer,
I waw just curious why you would want Conner to eat PB at all? I am not judging at all, but just curious. My parents live here in town and my mother lived on PB(literally), and when we found out about my first child's PA, she would not touch it with a 10 foot pole. No one eats PB or any candy with peanuts/tree nuts at all-even when they are out of town. We are just trained that way now, and I could never imagine letting any of my kids have something the other is deadly allergic to.
Just wondered if anyone else is this "paranoid" or is it just my family (and friends too?)
Remember-not judging. Just want to understand different views.

I didn't think you were judging at all. In doing all of this research regarding nut allergies, I read in a few places that denying nuts can lead to a nut allergy in children. Not sure if it's true, but then again, I don't know if it's not true either (need to find the info again - had a computer meltdown shortly after).
Aiden will live a life without nuts but let's face it, it may not always be an easy one. Not sure I want to put Connor through that as well. There is no way I would give Connor nuts without a thorough screening down the road and a food challenge in the doctor's office. He is negative right now but have learned that could change. My mom does eat PB because of her diabetes - never around Aiden though. IF I was allow Connor to eat PB it would probably be on a solo overnight visit to my parents house. I have a good five years before we have to face this decision - maybe my thoughts will change.
Insomnia and PA is a bad thing, I tell you. The thoughts that roll through my brain when I'm trying to convince myself to sleep...

In my opinion, and this may sound out there for some, but I've been dealing with allergies for 10 years and when I found out my son was allergic I stumbled across diff websites and from my research I believe that allergies come from toxicity or congestion of the liver/gall bladder. I became allergic to peanuts after I was on antibiotics for too long. I wonder about vaccinations also (I do believe that we need to vaccinate for some things, but today I think they give vaccines for too many things which can weaken the immune system) which causes auto-immune disease which can cause allergies to foods/meds. Think about how common food allergies are now and how there are more and more and also the controversial issue of autism. Think about how many people are getting their gall bladders removed at an even younger age. Did this happen years ago. I just think something is different and we are not as healthy as we used to be. Sometimes I think I should have let my son eat dirt when he was a baby. I guess we can never really figure it out, but that is what I believe.

momll70 - I have my thoughts too. Have to wonder about vaccinations...oldest had his through 9 months (stopped due to increased eczema issues, didn't want to use steroids, seemed smarter to stop the vaccinations for the time being) and has LOTS of food allergies. Given our history, we opted to wait for Connor as well. Connor has had no vaccinations and has no food allergies. Wonder about all that anti-bacterial soap - read somewhere it could cause the body to fight food protein because it doesn't have germs to fight. Used lots of it while pregnant with Aiden and after...none with Connor. And then I wonder about soy and how they have genetically modified it to add to our food. Didn't really follow a diet when pregnant with Aiden or while breastfeeding. After he was diagnosed with soy allergy, I tried to cut as much of it out of my life as humanly possible...gee, Connor has no allergies.
Having said all that, we have a family history of allergies and asthma. Aiden could have just spun a big bankrupt on the genetic wheel of fortune while Connor hit jackpot. I wish I had the answers, because I would love to share them all with you. For now though, I'm busy trying to keep my little ones as safe as possible.
