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.

Chronic Urticaria and Low Histamine

I have played with a low histamine diet for James, as it is a fairly common on-line (read: not doctor) recommendation for those with chronic urticaria. And then, last week there was this article:

"A Popular myth – low-histamine diet improves chronic spontaneous urticaria – fact or fiction?"

The points I felt most significant were:

1) they were on the diet for 3 weeks (which truly, is a very short time)
2) 75% of the participants had some improvement
3) 61% reached the endpoint goal of the study

The specific diet they used in the study is not mentioned in the abstract. I would love to see it. Part of my halfheartedness in using a low histamine diet exclusively is that there is so much on-line information, and a lot of it does not agree.

The other issue I have had in completely embracing low histamine is the mental effects. For an already food restricted teen, having to lose more food for a more nebulous health reason (that is, more nebulous than a clear food allergy) is distressing.

Here is how I have handled it:

1) No leftovers. I am trying to adhere to this as strictly as I can. I was a huge leftovers fan. With only three of us, it was easy to cook a meal and then use whatever was leftover in a meal later in the week. James had what we think was a histamine type reaction (leftover tuna, spinach, and blue cheese in a salad) and Dr. Li specifically advised against leftovers (and limiting blue cheese, which we have been fairly successful with).

2) Emphasizing the foods he can eat, trying to add in more of those foods which are low histamine rather than eliminating all the high histamine ones. My thought with this is that if he is full of low histamine foods, he will be not eat as many high histamine ones.

I have been using this list because I like how it is organized. Dr. Bowdish kindly replied on twitter with this option 

.@hollysjoy I've used a variation of this list from Allergy & Immunology Associates of Michigan https://t.co/eUufyigd6x

It's one I also like because of it's clarity and limited nature (ie. not every food you eat is listed as high histamine).

These two reasonable steps are working for us. If this article had been posted when James had active and severe chronic urticaria, I would have done a stricter version, at least for three weeks to see any results.

At this point in James's life, I try to make any dietary changes or limitations part of teaching him how to eat as an adult, not that far away. In some ways, his diagnosis was the best thing that happened to him, because he had no idea one could eat without, in particular digestive, pain.  He is learning to listen to his body and eat accordingly. And this will serve him much longer in life than if I forced a certain diet.

Misdiagnosis

Allergies are particularly prone to misdiagnosis but, the truth is, as you can see in the infographic below, misdiagnosis is a common problem.

Part of this, I believe, is that doctors play the game of statistics. They are looking for the ordinary, what they see most frequently. In general, they get it right (19 out of 20 times). But, what if you are that one?

James was diagnosed by his first pediatrician with lactose intolerance, based on symptoms and statistics. Once he had that diagnosis, it was used by every doctor he saw to explain his frequent diarrhea and cramping. I was obviously not being careful enough with his diet. Eventually, I couldn't stand it anymore and removed all dairy, in all forms, from his diet and discovered for myself that lactose intolerance was not the problem.

Unfortunately, his gastrointestinal problems are returning. In talking to Dr. Li, explaining to her why he was misdiagnosed for so long, she said, "But of course you were careful enough!"

And truly, I was. Not that I can't make mistakes, but I didn't make nearly a decade of mistakes. I should have advocated, both for myself and for James, to get more testing and intervention sooner.

And honestly, I need to keep this in mind, because I am not convinced we have reached the end of his diagnostic tangles.
