What does this mean?

My daughter had positive blood tests and so I had my son tested. All his tests were negative except Gliadin (deamidated) which was 15.9, a positive is over 15. Does that mean I don't have to worry or would you push for more testing?

A positive deamidated gliadin antibodies (DMG) test means that your son also likely has celiac disease, and will need to go gluten-free. His doctor may want to run more tests, but given that his sister has been diagnosed with celiac disease, his doctor may be able to make the diagnosis without doing an endoscopy.

"Positive test results for deamidated gliadin antibodies, IgA or IgG, are consistent with the diagnosis of celiac disease."

Be sure to discuss this with his doctor.

Thanks. Even though everything else was in normal range? 

Obviously I'll talk to his Dr., but he happens to be on vacation right now so I'll have to wait. 

It would be a crushing diagnosis for him as he thinks bread is life.

Unfortunately this single positive ought to be enough to make a diagnosis, but it's possible his doctor will want to also do an endoscopy to confirm it. For kids the DMG test seems to more accurate than the others, but if you have those other results feel free to share them with the reference range.

Here is a screen shot of the results. Hopefully. You should see everything else is negative and his Iga seems to be in normal range. Unless I'm reading it wrong.

In children the DMG test is the most reliable, and it only takes on positive result to indicate celiac disease...all results do not need to be positve.

      Has anyone found Ozempic affected their symptoms?

      By Wheatwacked · Posted

      Could be the Ozampic is masking your expected symptoms.  Like an analgesic masks pain.  Qzampic slows digestion to lower the rate glucose enters the intestine to slow its effect on glucose level.  It seems it might also slow down the gluten entry into the intestine, reducing its trigger level for the antibodies.  Ultimately the damage from gluten is the same, just not as fast so the pain is less.  Sourdough bread has less gluten.  Ozampic siows its entry.

      Options - 7 year old boy - Helicobacter pylori and serology

      You can sell it better if the whole family does gluten free.  If he does have Celiac Diease, it is genetic so either you, your spouse, or both have a 40% chance of also having Celiac.  There are over 200 non classic symptoms also caused by celiac disease not often considered by doctors. Joint pain, muscle pain, muscle cramps, osteoporosis, and allergies for starters.

      On the cusp of facing a new life of managing a life with Celiac Disease

      By Wheatwacked · Posted

      Hello @MHavoc, thank you for your question and welcome to the clinic. First, has the contstipation abated with the GFD? If your are pursuing further diagnostics you must continue to eat gluten. Each lab has their own reference range for their test, but they indicate an H for high.  Typically anything above 11 is considered positive. Mild chronic inflammation (gastritis) can interfere with intrinsic factor for B12 leading to low B12 causing low MCHC (anemia). So what is causing your gastritis?  A high tTG IgA level generally indicates potential gastrointestinal problems most commonly associated with celiac disease.  Although the biopsy is the Gold Standard for diagnosis, not finding damage in the biopsy does not rule out Celiac Disease. It means they did not find damage where they looked.  The small intestine is over 20 feet long. Many here have been blood positive and biopsy negative, it just delays the diagnosis until you have enough damage to find and fit their diagnostic profile. The Ttg-iga is not only sensitive (90%) but highly specific (98%) and won’t show positive until the damage is severe.  It is estimated that 40% of first degree relatives of diagnosed Celiacs have undiagnosed Celiac Disease, so your sister is a big risk factor in whether you have it. Are You Confused About Your Celiac Disease Lab Results?  This article explains it better and is quite readable. Celiac Disease can cause deficient vitamin D.  Low vitamin D compromises the immune system.  Any other symptoms? liver enzymes?  Recent cold or flue? Celiac Disease and the malabsorption it causes through vitamin and mineral deficiencies can elicit symptoms not usually associated with Celiac Disease. Case in point maybe your gastritis and anemia.

      On the cusp of facing a new life of managing a life with Celiac Disease

      As with most of the people that come here, I have questions and need perspective/info from this wonderful community.  Some background, started having severe constipation that would not abate even with softners (not really fun to talk about), so I was able to finally get in to see my primary and she scheduled some blood work.  One of things she wanted to test for is Celiac Disease due to my sister having celiac disease since a young child. Here are my test results: MCHC = 31.4 so considered slightly low TISSUE TRANSGLUTAMINASE AB, IGA = 78.8 H So with that result, I was scheduled for an endoscope for confirmation of celiac disease, but I am very confused with the results: Diagnosis 1. Duodenum, biopsy: -No pathologic alteration. 2. Stomach, biopsy: -Mild chronic inflammation with reactive epithelial change -H. pylori not identified on immunostained section. -No intestinal metaplasia or dysplasia I am now scheduled to meet with a GI Specialist from the Celiac team, but that won't be until after the New Year.  I would appreciate thoughts about the biopsy report to understand whether it confirms the celiac disease as was indicated by the blood test results. I have been gluten free for two weeks and it is a very difficult adjustment for me as an older 50+ person.

      Anyone else have intermittent left ear ringing and outer right ear pain? Both seem to happen in the evenings.
