Today we did an IOFC for sesame. We had to be there at 8:40, which probably doesn't sound too bad, except driving from where we live, to where the doctor's office is, isn't the easiest thing during rush hour =) But we made it in time (barely), and even scored a front row parking spot. I took that as a good sign!
For the challenge, I brought in a package of Stella D'Oro sesame breadsticks - I chose that brand because they labeled for sesame on their packages, so I took it as a good sign that they were on top of labeling, since sesame isn't a requirement. The challenge started with them taking Luke's blood pressure, and then bringing in 2 sesame seeds. Getting him to eat the seeds was a bit of an issue, but nothing that a few sips of water didn't take care of.
After 15 minutes they came in and looked for any sign of hives, took his blood pressure again, and then moved on to 1/16th of the bread stick. The entire challenge went like that - a slightly bigger serving of the breadstick, followed by 15 minutes of waiting, then observing and taking his blood pressure before being given the next bigger serving.
At one point I found a few small red bumps on his lower back -the allergist decided that they weren't hives. Other than that, there weren't any questions- he passed the challenge!
This is great news for us - no more worrying about sesame. Sesame is HARD. Sesame isn't one of the top 8 allergens, so food companies aren't required to label for it, or even include it in the ingredient listing. If you see an ingredients listing and it says "spices", sesame could be lumped into that.
I will say though, that there is a slight downside to it. When his anaphylactic reaction happened after eating at Burger King, I immediately suspected the sesame seeds on the buns. And I did this because a couple weeks earlier, he had eaten a cracker that had sesame seeds on it, and he had gotten a few hives around his mouth. So when we saw the allergist after the BK debacle, he did a skin test for sesame and it came back positive. So even after our current allergist determined that he has a major egg allergy, I held onto some hope that the reaction at BK was a combo of egg+sesame making things worse.
When that reaction happened, he had eaten a tiny amount of the cheeseburger (just picture a Burger King Jr Whopper, and imagine how much mayo is on there- then imagine how big the bites would be from a tiny 18 month old -not very big, so not a whole lot of mayo consumption there). With sesame out of the picture as being a possible issue that day, it shows how serious his egg allergy is. And that, of course, scares me. There's a pattern there between the egg reaction, and the peanut reaction - two tiny bites, very little consumption, and a severe reaction.
Also, another point here- this is a good example of how the only true food allergy test is what happens when you EAT the food item. Skin prick tests (SPTs) can be wrong. I'm thankful that his current doctor knew enough to do a challenge, so that we wouldn't have to go through unnecessary avoidance/stress.
Next up - She wants us to give him shrimp. His blood test was negative for shrimp and crab, but I'm still a bit nervous. We'll be trying it this coming weekend though. Fingers crossed that it goes well!
