Just got genetic testing fm Mayo.  Allergy blood tests done yrs ago showed I was allergic to glutens, so I went gluten-free then.  After that, osteporosis doc was looking for why I got osteoporosis at an early age, he found antibodies.  GI doc did endoscopy, which was okay, he said maybe b/c I had been gluten-free so long (although he had me start on gluten about 6 weeks prior to the test).  My niece was just diagnosed 6 months ago.  New GI dr. ran following...  DQ Alpha 1  01:02, 05:01    DQ Alpha 2  02:01, 06:02  Celiac gene pairs present?  Yes.  I'm thinking these are postive results, right?

Gene testing just means you have the genetic make up for Celiacs but it does not mean you have celiac for sure.  Are they going to do bloodwork for the actual Celiac testing since you went back on Gluten?

I'm not sure what you mean.  I haven't gone back on gluten.  The blood tests before showed the antibodies, the GI dr. didn't feel it was necessary to repeat those tests.

If you had a positive celiac test before, you have Celiac. If you had allergy testing, you did not test for Celiac. This may just be a confusion of word usage? I am not sure why you would be re- tested for Celiac if you were tested for it before.

Edit : your dogs are adorable!

I've had three forms of blood tests that relate to gluten.  Years ago, glutens tested positive when I had allergy blood testing.  Then, a couple of years after that, when my gyn was running blood tests, looking for possible reasons for my early-onset osteoporosis, the one test that was positive was one that showed antibodies for celiac.  Then, I had this latest genetic testing which I can't interpret the results of.

Welcome to the board.  :)

 

For genetic tests that place one in the high risk group for celiac disease are the DQ2 and DQ8 genes.  It looks like you have the DQ2 gene which means you are one of the 30% of the world's population who is at an increased risk of having celiac disease.  I think it is somewhere around 97% of all celiacs have the DQ2 or DQ8 genes.

 

I'm not sure why the doctor ran the genetic test for celiac disease on you since you said you positively tested for the autoantibodies found in celiacs - usually the tissue transglutaminase, endomysial antibodies, or the deaminated gliadin peptides tests. If one of those is positive, you have a gluten sensitivity that took the form of celiac disease, which is an autoimmune disesse that can run in families.  There is not any real need to do the genetic tests if one of those is positive. Even if the endoscopic biopsy is negative (intestinal damage is missed in up to 20% of celiacs) you still have celiac disease.

 

Medically speaking, there is not actually an allergy to gluten.  People can have a sensitivity to gluten, or they can be allergic to things that contain gluten like wheat, but a gluten allergy does not really exist.  An allergy is an IgE reaction and gluten doesn't cause that.

 

And kudos to your doctor for thinking of celiac disease when you presented with early osteoarthritis.  Not many doctors would have made that connection.

I would say you have Celiac by the test results, the genes, and the fact that you developed Osteoporosis early. 6 weeks of gluten prior to an endoscopy isn't enough.. They usually have you shoot for 12, so that's probably why they didn't see any damage. I'd keep going gluten free if I were you.

Thanks, everyone.  And, interestingly (and maybe why my newish GI ran the genetic testing), my 21-year-old niece was just diagnosed with celiac a few months ago.

You said in your first post that your GI had you go back on Gluten 6 weeks before your scope.  We would have to see your actual tests and results to give you better answers but like other's have said, the allergy testing is not Celiac testing.  Can you get your results from before?

Welcome!

Wow, what are you doing for the Osteoporosis? If you were gluten free for all those years, how did the osteoporosis develop? Perhaps, you were not as gluten free as you thought. Cross contamination is a big issue. I highly recommend reading our Newbie 101 section under the "Coping" section of this forum.

Here is the link:

Take care!

Do you mean the test the gynecologist ran?

I am getting confused.  Maybe start over?  Why would the GI put you on a gluten challenge if you were diagnosed years ago?  Did he run any blood work after you were eating gluten?  If you had been gluten free for years - the Celiac blood work shouldn't have been positive (the one the OB?GYN ran?).  

 

 

You may want to get a copy of all your medical records to see if you were actually tested for Celiac or not.  It sounds like you probably have it but a genetic test only tells you that you are 1 of the 30% of people with a gene that could be activated at some time (but for most, will not be activated as only about 1% of the population have Celiac Disease).

      Have I got coeliac disease

      And I agree with Wheatwacked. When a physician tells you that you can't have celiac disease because you're not losing weight, you can be certain that doctor is operating on a dated understanding of celiac disease. I assume you are in the UK by the way you spelled "coeliac". So, I'm not sure what your options are when it comes to healthcare, but I might suggest...

      I have osteopenia and have cracked three vertebrae.  Niacin is connected to osteoporosis! Do talk to your nutritionist and doctor about supplementing with B vitamins.  Blood tests don't reveal the amount of vitamins stored inside cells.  The blood is a transportation system and can reflect vitamins absorbed from food eaten in the previous twenty-four to forty-eight hours.  Those "normal limits" are based on minimum amounts required to prevent disease, not levels for optimal health.   Keep us posted on your progress.   B Vitamins: Functions and Uses in Medicine https://pmc.ncbi.nlm.nih.gov/articles/PMC9662251/ Association of dietary niacin intake with osteoporosis in the postmenopausal women in the US: NHANES 2007–2018 https://pmc.ncbi.nlm.nih.gov/articles/PMC11835798/ Clinical trial: B vitamins improve health in patients with coeliac disease living on a gluten-free diet https://pubmed.ncbi.nlm.nih.gov/19154566/   Nutritional Imbalances in Adult Celiac Patients Following a Gluten-Free Diet https://pmc.ncbi.nlm.nih.gov/articles/PMC8398893/ Nutritional Consequences of Celiac Disease and Gluten-Free Diet https://www.mdpi.com/2036-7422/15/4/61 Simplifying the B Complex: How Vitamins B6 and B9 Modulate One Carbon Metabolism in Cancer and Beyond https://pmc.ncbi.nlm.nih.gov/articles/PMC9609401/

Anemia?  Do you take any supplements, or vitamins? I’m within healthy range for nutritional tests, thyroid and am not anemic. I do have osteopenia. I don’t take any medications, and the dietician was actually a nutritionist (not sure if that is the same thing) recommended by my physician at the time to better understand gluten free eating.    I almost wish the gluten exposure had triggered something, so at least I’d know what’s going on. So confusing!    Many thanks!

      @JudyLou,  I have dermatitis herpetiformis, too!  And...big drum roll... Niacin improves dermatitis herpetiformis!   Niacin is very important to skin health and intestinal health.   You're correct.  dermatitis herpetiformis usually occurs on extensor muscles, but dermatitis herpetiformis is also pressure sensitive, so blisters can form where clothing puts pressure on the skin. Elastic waist bands, bulky seams on clothing, watch bands, hats.  Rolled up sleeves or my purse hanging on my arm would make me break out on the insides of my elbows.  I have had a blister on my finger where my pen rested as I write.  Foods high in Iodine can cause an outbreak and exacerbate dermatitis herpetiformis. You've been on the gluten free diet for a long time.  Our gluten free diet can be low in vitamins and minerals, especially if processed gluten free foods are consumed.  Those aren't fortified with vitamins like gluten containing products are.  Have you consulted dietician?  Have you been checked for nutritional deficiencies?  Osteoporosis? Thyroid? Anemia?  Do you take any supplements, medicine, or vitamins? Niacin deficiency is connected to anemia.  Anemia can cause false negatives on tTg IgA tests.  A person can be on that borderline where symptoms wax and wane for years, surviving, but not thriving.  We have a higher metabolic need for more nutrients when we're sick or emotionally stressed which can deplete the small amount of vitamins we can store in our bodies and symptoms reappear.   Exposure to gluten (and casein in those sensitive to it) can cause an increased immune response and inflammation for months afterwards. The immune cells that make tTg IgA antibodies which are triggered today are going to live for about two years. During that time, inflammation is heightened.  Those immune cells only replicate when triggered.  If those immune cells don't get triggered again for about two years, they die without leaving any descendents programmed to trigger on gluten and casein.  The immune system forgets gluten and casein need to be attacked.  The Celiac genes turn off.  This is remission.    Some people in remission report being able to consume gluten again without consequence.   However, another triggering event can turn the Celiac genes on again.   Celiac genes are turned on by a triggering event (physical or emotional stress).  There's some evidence that thiamine insufficiency contributes to the turning on of autoimmune genes.  There is an increased biological need for thiamine when we are physically or emotionally stressed.  Thiamine cannot be stored for more than twenty-one days and may be depleted in as little as three during physical and emotional stresses. Mitochondria without sufficient thiamine become damaged and don't function properly.  This gets relayed to the genes and autoimmune disease genes turn on.  Thiamine and other B vitamins, minerals, and other nutrients are needed to replace the dysfunctional mitochondria and repair the damage to the body.   I recommend getting checked for vitamin and mineral deficiencies.  More than just Vitamin D and B12.  A gluten challenge would definitely be a stressor capable of precipitating further vitamin deficiencies and health consequences.   Best wishes!

      And I agree with Wheatwacked. When a physician tells you that you can't have celiac disease because you're not losing weight, you can be certain that doctor is operating on a dated understanding of celiac disease. I assume you are in the UK by the way you spelled "coeliac". So, I'm not sure what your options are when it comes to healthcare, but I might suggest you look for another physician who is more up to date in this area and is willing to work with you to get an accurate diagnosis. If, in fact, you do not have celiac disease but you know that gluten causes you problems, you might have NCGS (Non Celiac Gluten Sensitivity). There is no test available yet for NCGS. Celiac must first be ruled out. Celiac disease is an autoimmune disorder that damages the lining of the small bowel. NCGS we is not autoimmune and we know less about it's true nature. But we do know it is considerably more common than celiac disease.
