IgA Symptoms and Heredity - ADVOCATE

It's so frustrating to have to advocate so hard for this little understood disease!  After suffering for years, I finally landed on Celiac for myself.  My sister and niece have both been diagnosed.  Now, my 12  year old daughter is having all manner of GI symptoms and the bi-lateral rash.  I asked for the antibody panel, it was completed, and IgA came back at 265.  Doc said, "You can't really tell anything by that number."  Period.  I called the GI specialist office who confirmed, yes, especially in combination with her symptoms and heredity, she should be referred to them for further investigation.

Am I losing my mind, or was I right to pursue?  I hate second guessing myself …

You sound like you are on the right track.  By bilateral rash I assume you mean she has a rash on both elbows, knees, hands or other?  A symmetrical rash like that is typical of DH (dermatitis herpetiformis).  DH is a skin condition that only people with celiac disease get.  They test for DH by taking a skin biopsy from clear skin next to a lesion.  The biopsy sample is tested for IgA antibodies.  If she does have DH then she has celiac disease, no endoscopy to confirm is needed.

There is a section of this forum just for DH that has more information.

And welcome to the forum! :)

Yes, I'm referring to the symmetrical rash.  She's got it on both legs.  I had it and it was the WORST.  Thanks for the welcome.  I appreciate it!  And also, thanks for the confirmation.

I am confused.  She had a celiac antibody blood panel?  That would include an Immunoglobulin A (IgA) test that, if in the normal range (and your child’s result seems like it is based on national labs), would validate the celiac specific TTG, EMA and DGP IgA tests.  An IgA test by itself, would just indicate possible Immunoglobulin issues like an IgA deficiency which would mean your kid might be sick with every cold, etc. She is exposed to.  Know that those celiacs who have DH often fail the blood tests, yet they do have intestinal damage.  Make sure you actually had the celiac panel run (DGP, TTG and EMA).  Make sure that your kid has been consuming gluten a solid 8 to 12 weeks prior to the blood or skin biopsies (less time for intestinal biopsies).  If she is in a gluten light, the tests may be invalid.  (Not sure if you are gluten free and that could impact her tests.)

Getting a dermatologist to do the skin biopsy can be tricky.  If not done properly, you could be left in diagnostic limbo land.  Here is some information you can share with a dermatologist who might not be celiac/DH savvy:

I encourage you to keep researching.  It is your best defense!

      There is a 10 year old post in this forum on Edy's and Dreyer's ice cream. The information is somewhat outdated and the thread is closed to further comment, so here is a new one. Edy's And Dreyer's Grand Vanilla Bean Ice Cream - 1.5 Quart is labeled "Gluten Free". This is a different answer than years gone by. I don't know the answer for any other flavor at this moment. On 1 May, 2026, Edy's website says: "As a general rule, the gluten in Edy's and Dreyer's® frozen dessert products is present only in the added bakery products, such as cookies, cake or brownies. We always label the eight major food allergens on our package by their common name. We recommend to always check the label for the most current information before purchasing and/or consuming a product. The exception to this rule is our Slow Churned French Silk frozen dairy dessert, which contains gluten in the natural flavors." https://www.icecream.com/us/en/brands/edys-and-dreyers/faq It seems that Edy's and Dreyer's are more celiac-friendly than they were 10 years ago. Once I found enough information to make today's buying decision, I stopped researching.

      probably not your situation @Mimiof2, but allow me to add one more to @trents list of celiac-mimics: "olmesartan-induced sprue-like enteropathy"

      My dad had an Abdominal Aortic Aneurysm.  Fortunately, it was discovered during an exam.  The doctor could feel my dad's heart beating in his stomach/abdomen.  The aneurysm burst when the doctor first touched it in surgery.  Since he was already hooked up to the bypass machine, my dad survived ten more years.  Close call! Triple A's can press on the nerves in the spinal cord causing leg pain.  I'm wondering if bowing the head might have increased the pressure on an aneurysm and then the nerves.   https://gulfcoastsurgeons.com/understanding-abdominal-aortic-aneurysm-symptoms-and-causes/ Abdominal Aortic Aneurysm Presenting as a Claudication https://pmc.ncbi.nlm.nih.gov/articles/PMC4040638/

      You have an odd story there. To me, the mechanical trigger suggests a mechanical problem and lower leg pain is a classic sciatica symptom. The fact that the clear mechanical linkage is no longer there does not take away from the fact that it was - maybe something shifted and the simple alignment is no longer there. There's also a good chance I am wrong and it's something else entirely. @Scott Adams's mention of shingles is interesting. It seems possible but unlikely to me, but who knows. However, I am writing here to reinforce the idea of getting the shingles vaccine. Ask anyone who has ever had shingles and they will bend your ear telling you how bad it is. I watched my wife go through it and it scared the bejeebers out of me. Even if you had the chicken pox vaccine, you really want to get the shingles vaccine.

      Oddly this effect has gone now, just happened yesterday evening, the nerve pain is now back to its usual "unpredictable" random self again - but that was the only time I ever had some mechanical trigger for it, don't know why! There's no (or wasn't) actual pain in my neck - it was inside the leg, but when I looked down, now though, the leg pain just comes and goes randomly as before again.
