Mouse,
I am interested in your child's non IGE mediated reaction to soy. My son also projectile vomited soy formula twice, but a month later on scratch and blood tests, he did not show an allergy. (they did show that he was allergic to all tree nuts and peanuts). That was 6 months ago. Last week we tried him on tofu, and three hours later he was vomiting all over his crib. The next day his stools were black.
Was you son able to tolerate soy oil? What about trace amounts of soy in other products? or soy lethicin (sp? -- my son seems fine with this). If I remember correctly, you said he grew out of it at 4 years old. How did you test? Thanks for the info.

Hi Everyone (just back from Vacation - fortunately our flights were uneventful...)
Anyway, my son just seems to be showing an egg allergy - as I have said before his first reaction was from getting egg whites on his hands and his eyes were swollen shut, he had hives and ended up in hospital for his asthma the next evening.
I have been trying to look for an egg substitute here in Canada and haven't had much luck. Does anyone know a brand name or anything that I can look for?
Thanks a lot

Deb O: We use Kingsmill Egg Replacer found in the Health Food Store. It's been good for cakes, pancakes, meatloaf etc..

San 103: My daughter's reaction to soy was quite severe. Projectile vomitting, followed by vomitting for about an hour, and then followed by dry heaves. Finally, collapsing in unawakenable sleep. She is now fine with soy products.

san103:
Sorry it took me so long to reply, I didn't see your post. To answer your questions:
A non-IGE mediated allergy to a food protein will not show positive on either skin or blood tests. These tests will only indicate whether there is an IGE mediated allergy. The way my son's doctors diagnosed the allergy was by his symptoms after he ate the soy protein. Specifically, projectile vomiting, dry heaves (for a long time), as I recall, the vomit from the soy formula resembled coffee grounds, and bloody stools. These symptoms occurred at 10 days old. When my son reached 4 months, the doctor had me try him again on the soy formula. The same symptoms appeared. Then I was told to avoid soy. I followed the recommendations of the Food Allergy Network as far as what ingredients to avoid. He was able to tolerate soy oil and soy lecithin. I tried to avoid all soy protein - even trace amounts. When he turned four, his doctors recommended that he undergo a food challenge. He goes to Johns Hopkins in Baltimore for his food allergies, so that is where we went for the food challenge. He was given soy protein. They have a protocol that they follow as to how much, and how fast it is given to the child. I don't know the particulars. He showed no reaction to the soy. He has eaten foods that contain soy protein many times since then with no reaction whatsoever. Hope this helps. Your child will probably also outgrow this allergy as well.

san103,
My son outgrew his soy allergy by 2 years of age. I presume it was a non-IgE mediated allergy, also. He had projectile vomiting as an infant to soy formula and had a negative skin test at 6 months. I avoided soy protein in my diet (he was breatfed) and his, although he did tolerate soy oil and soy lecithin with no problems. At 2 years of age, his skin test was again negative, and the RAST was very low. The allergist performed a challenge at the office. Good luck to you and your son!

My son was diagnosed as allergic to eggs, soy, and milk at the age of 6 mos. (We discovered the peanut allergy at age 2--the first time he had any.) He outgrew his milk and egg allergies by the age of 5, and had an uneventful soy food challenge at Arkansas Children's Hospital when he was 11. However, he does not like eggs unless they are cooked in other foods, so he has not had any big servings of them.
Good luck! There's hope!

My son is allergic to eggs and peanuts. The egg allergy was diagnosed through RAST testing because we had never seen a reaction. He tolerated eggs in baked goods and spit out the eggs the one time we tried to feed him scrambled eggs. We are currently avoiding all eggs, but the allergist expects him to outgrow his egg allergy before kindergarten.
Baking has been a problem. We have used the Ener-G egg replacers (available through mail order, but I also found it in my grocery store) with some success. I also bought a cookbook that was recommended by FAN that has been pretty good called "Bakin' Without Eggs" by Rosemarie Emro. It's marked $16.95 (US). The recipes are also peanut-free although not all are tree nut free. The ingredients are easy to find in the grocery store. I usually substitute vanilla extract for almond extract.
The biggest problem I find with the recipes is that the first batch of cookies is usually very undercooked even at the top of the given baking time, but that might be my oven. The good news about that is there is no salmonella risk without the eggs. Things also don't seem to brown well without eggs. I guess that's why so many baked items are topped with an egg wash.

Just a heads up regarding Ener-G foods. I e-mailed them to ask about possibility of peanut/tree nut contamination in their egg replacer. This is what they told me: Quote:Some of our products contain almond or almond oil and the granola bars and
granola contain tree nuts including almonds, walnuts, filberts and pecans.
I can't therefore promise absolutely no possibility of any contamination,
however we are very careful.
They also said the same thing in an earlier e-mail about peanuts. I don't feel safe using it anymore, so I substitute with the recipe from FAN, which is 1-1/2 tsp oil, 1-1/2 tsp water and 1 tsp baking powder mixed together (per egg).

We use Kingsmill egg replacer, I should give them a call.
