Soy Challenge Success!

As I have posted everywhere now (a wee bit excited and relieved), James passed his recent soy challenge. The challenge was a different from his previous one, not only in the fact that it didn't end with epinephrine, steroids, and fear.

Disclaimer: This is a description of one experience with a food challenge. It is not meant to be a guide on how food challenges should be run, medical advice, or anything besides a personal narrative.

Skin Test First

As I've mentioned previously, getting James to the point of no antihistamines for a skin test/food challenge has been difficult. So, we combined the skin test and food challenge into one day. I wanted to get all his skin testing done but the allergist (not James's usual allergist, more on that later) didn't want to stress him out too keep things fairly calm. So, we settled on three tests: soy, wheat, and peanut.

Have you ever seen a more perfect SPT?

I've forgotten which the nurse said was wheat vs soy, but no matter. The histamine reacted, the rest did not, and that was perfect.

A Group Challenge

I knew ahead of time that James would be having a group challenge but I wasn't entirely sure what that would entail, other than there would be other people. My primary concern was if people would be challenging other foods that he is allergic to. My secondary concern was snacks; they had told us to bring snacks but I didn't want to bring something that would be a problem, allergy-wise, for someone else.

What I didn't know until we got there was that James's usual allergist would not be preforming the challenge. I did a fair amount of acting like it was no big deal (and it turned out not to be because the allergist running the challenge was excellent), James likes and trusts his allergist, not allergist's in general. I was concerned he would balk, but he did great (the entire time).

I am not sure how many offices do group challenges. Our experience was in Kaiser San Diego. I asked about the rational (mostly to make conversation because we were there for almost four hours). There is a long wait list (no kidding!). When they have one on one challenges, the primary person preforming the challenge is a nurse (this was our previous experience) and you only see the allergist if there is a problem or at the end. Kaiser is actually shorter on nurses than allergist. The allergist is able to monitor up to four patients at a time whereas the nurse can only monitor one. So, they can move the list faster by having an allergist do four challenges at once. 

I actually liked it better, because the allergist was in the room the entire time, mostly working on paperwork, but there. The allergist did say that they only schedule group challenges for the patients they are most confident will pass.

General Procedures

I believe James drank a total of eight ounces of soy milk, divided into seven different doses. He started with a drop on the tongue and ended with 4 ounces in a cup. There were 15 minutes in between each dose and an hour waiting at the end. He was allowed to drink Gatorade in between doses. Although he complained of the taste, he drank the doses quickly. Except for complaining that the soy milk was disgusting enough to make him want to vomit (quickly adding it was an opinion not a physical reaction), the challenge literally went that smoothly with no hiccups or concerning signs at all. 

Epi-Pen Information

Since we were there, I decided to ask the allergist about Kaiser's Epi-Pen policies. This is from casual conversation and not a "written in stone" policy. According to the allergist, Kaiser Southern California will not be switching to the generic Epi-Pen this year but will be staying with Mylan brand (depending on your plan, of course, but the allergist's first choice will be to write an Epi-Pen prescription). Kaiser is "not really" a commercial plan and the allergists will not be filling out vouchers for Auvi-Q. I did not push this at all, because James is comfortable with the Epi-Pen, having used it before, and I am not looking to switch. If I were, I would definitely question this decision.

Next Steps

We were advised to have James keep soy in his diet 2-4 times a week. I can tell you from his complete disgust during the challenge he won't be consuming soy milk. I'm going to try both tofu and edamame as two sources high in protein, hopefully he will like one or both of them.

James has a wheat challenge in a couple weeks, same allergist, same group challenge. I am hoping now that we have done this once, know the procedure, and he's passed, it will be emotionally easier. It will certainly taste better and so be easier in that respect. I was so proud of James, because he was (outwardly) so calm and composed about the entire challenge. It was not easy for me to stay calm so I can only imagine for him.

This weekend, he will be trying fresh tomato at home (he has OAS to it, but never a severe reaction). I am supposed to contact his allergist when he, presumably, passes. He passed! At that time, I will ask to be put on the wait list for peanut, as well as ask about trying mango and watermelon at home.

The wait list is four to six months, and to be honest, I think we will be glad for the break and will try mango and watermelon at our leisure while waiting. Tree nuts would be the next step, but James is not ready to think about that at this point.

An Apple Every Two Years

is apparently not enough to keep the doctors away.

But, here is James, his first apple in two years.

His Apple History:

He reacted to a fruit salad (no apple) on June 30, 2014, the day before his 12th birthday. He had a two system reaction and so self administered his epi-pen. Later that summer, he got an itchy mouth when eating apple, although he had applesauce earlier that day with no reaction. This disparity led his allergist to test him for oral allergy syndrome (OAS). In one of those weird twists, he did not test positive for apple (on the fresh apple skin test, no IgE was taken). However, he tested positive for other fruits and vegetables, including the melon that we now know caused his reaction.

His allergist advised me that we could do an at home challenge for apple. However, at the time, he was having issues with more and more foods and we were in the process of simplifying his diet. He had no desire to try apple. Since he could eat most apple products, just not fresh apple, we left it alone.

Fast Forward:

He has improved immensely, both physically and emotionally. His IgE for grasses, which is what causes his OAS allergies, are now nearly negative (0.24 and 0.37, a 90% and 89% reduction). We are joining friends this weekend on a hike followed by apple picking; he wanted to be able to eat an apple.

So, we decided to go ahead with the challenge recommended two years ago.

Please note: I am not giving medical advice or recommending you follow these steps. I am describing the steps recommended only in this particular case by a board certified allergist. If you have questions specific to you or your child, please consult your own board certified allergist. Thank you.

What was supposed to happen:

1. Take a thin slice of apple, put it to his lips, wait 15 min.

2. Microwave a small slice of apple for 10 sec. Take a nibble. Wait 15 min.

3. Slowly finish the microwaved slice over 15 min. intervals.

4. Repeat with a fresh slice.

5. Continue eating more until an entire apple has been eaten.

What did happen:

1. Hand James the apple slice to put to his lips.

2. He eats before I can say anything.

3. "What, was I not supposed to eat it?"

The results:

The first day he tried apple (about half of the entire apple), he got some very minor digestive problems. This is not entirely out of the ordinary for him and he was likely nervous. So, we stopped for the day and said we would come back to it.

Two days later, he finished an entire apple with no symptoms. And just like that, one food is down.

Moving Forward:

I plan to celebrate this victory for a while before moving forward. Whether he never had OAS to apples or he if his environmental allergies improved enough that he can now tolerate it, it is a victory. He is confident enough that he will try foods he has been avoiding.

The next food I plan to re-introduce is green beans. His allergist also felt that his issue with legumes is more of an intolerance. Legumes are histamine liberators. Since he has had a histamine type reaction, it is possible that, while his body was recovering from a reaction in particular, he had trouble digesting them. I will not be home trialing any that he was specifically tested for (all were positive) without discussing with his allergist. But, I am ready to lift the "avoiding legumes" label if possible.

Update:

In perfect irony, James got sick, so we will not be going apple picking this weekend. Nothing to do with apples or allergies, just your standard virus. Considering that in two years, he has not had a fever ever, I am debunking the "apple a day keeps the doctor away" advice.

Food Fear Factor

"He's just anxious."

How many of us know someone who has the flu and afterwards, for a time, avoids the food they ate  before the flu started? Logically, they know that pasta dinner did not cause the flu, but physiologically, their stomach turns every time they look at a plate of pasta.

Now imagine that instead of throwing up, that plate of pasta made it difficult to breathe, caused you to be rushed to the emergency room, ended with shots, and tests, and medications, and more tests. Is it surprising that a child looks at everything on the table that night and says, "I don't want to eat that."?

Allergic Living recently published an article, "5 Reasons Patients Shun Critical Food Allergy Testing." Number three on the list was fear of the oral test.

Allergists have (among other things) the job of determining what is safe to eat.  Lives and, depending on the circumstances, nutrition, can be improved by broadening the diet. But, allergists can also undermine the confidence of patients by dismissing fear as "just anxiety."

Our Experience:

James does not test allergic to apple. It was one of the foods he was tested for OAS for. In fact, it was the food that caused a reaction that made the allergist think he had OAS, yet the testing was negative. Since the testing was negative and OAS generally results in minor reactions, the allergist recommended we test apple at home. We haven't. James has no interest in eating apple (he does eat cooked apple). I don't care. He eats plenty of fruits. If he never eats another apple, he is not missing out nutritionally.

Last October, right before our first appointment with Dr. Li, James's allergist recommended a food challenge for soy and wheat. Dr. Li suggested we wait. James implemented a two allergist agreement rule for any food challenge so we are waiting. We would have waited on Dr. Li's request anyway. The time of waiting has been good for James. It has given him time to think about adding in the food, about what a challenge would be like, pass or fail. There are times when anticipation increases anxiety, but this has been about working towards a goal, with each swallowed pills and slather of cream, he takes back some control.

So, if all the tests look good in October, then those are food challenges he will complete. Soy and wheat, unlike apple, would make a huge difference in all of our lives. And, I expect, when the time comes, we will all be a little anxious. But, having taken time and allowed confidence to re-grow, I don't think it will be unmanageable.

Advice to Parents

You know your child. You need to make a careful consideration of all the factors and come to a decision. It's not a time to allow outside pressure from anyone - allergist, family members, strangers writing blogs - influence you, however well meaning they are.

1. Take your time. 

2. Work with your allergist.

3. Don't be afraid of taking your child to a therapist if needed. According to this toolkit from the National Eating Disorders Association, presence of a food allergy is a risk factor for an eating disorder. Obviously, most people with food allergies do not develop an eating disorder, however, if you notice that your child has developed extreme fear or avoidance behavior, professional intervention may be needed.

4. Celebrate your successes. I find this can be a one step forward, two steps back process, so we celebrate every step forward.
