Hi all.  Just getting started to see if the dreaded celiac disease has encroached into my world.  I been eating a lot of gluten products preceding labs tests.  I got a few of the results back.  What is your take on them?  That is, if you care to comment on them.  I am not seeking medical advice, just some thoughts from those who have experience.  Blood values not give just interpretation.

TOTAL IGA:  NORMAL
TTG, IGA:  NEGATIVE
TTG, IGG:  NEGATIVE
Endomysial Antibody IgA:  NEGATIVE
Deamidated gliadin peptidic (DGP) antibodies, IGA:  POSITIVE
Deamidated gliadin peptidic (DGP) antibodies, IGG:  POSITIVE

 

Thanks for reading and good luck to all.....

It looks like you have two tests that indicate celiac disease. One does not need to have all of the tests positive in order to have it.

Do you have the levels measured and standard ranges for those tests? I.e. are they borderline raised or very high?

In young children, anti-DGP antibodies come up before anti-tTG but don't know if this is true in adults.

Yes, anti-DGP testing is valid in adults.

Antibodies against deamidated gliadin peptides identify adult coeliac disease patients negative for antibodies against endomysium and tissue transglutaminase

Thank you all for the valuable info.  Its been a little troublesome for me and my Dr because I also have Cutaneous and Systemic Lupus as well as Sjogrens Syndrome.  For instance, my 2 rash biopsies reports, one of which is a DIF, state clinically it looks like DH but cannot rule out lupus either.  But due to other symptoms etc.  I feel its DH.  I am never rash free.  I always get eczema and scle rashes but the one on my elbows is blistering and I never seen that before.   I guess my next stop will be the GI doc.  Not looking forward to being scoped.

Thank you again.  Your info is very helpful to me.

That looks like a strong positive for anti-DGP antibodies. It is also possible to have antibodies against related enzymes tTG3 and tTG6 rather than the tTG2 that you were tested for. tTG3 is implicated in DH, and tTG6 in gluten induced neuropathy (GIN). Few centres test for these specific antibodies at the moment. It is also possible to have DH or GIN without showing gut damage.

      Hidden Gluten in distilled vinegar

      By knitty kitty · Posted

      @Manaan2,  I'm so happy to hear you're going to try thiamine and magnesium!  Do let us know the results!   You may want to add a B 50 Complex with two meals of the day to help boost absorption.  Thiamine interacts with each of the other B vitamins which are all water soluble.   When supplementing magnesium, make sure to get sufficient calcium.  Calcium and magnesium need to be kept in balance.  If you choose a calcium supplement, take two hours apart from magnesium as they compete for absorption.  Take Calcium with Vitamin D.  Vitamin D helps calm the immune system.   For pain, I use a combination of thiamine, B12 Cobalamine, and Pyridoxine B6.  These three vitamins together have analgesic effects.  My preferred brand is "GSG 12X Takeda ALINAMIN EX Plus Vitamin B1 B6 B12 Health Supplementary from Japan 120 Tablets".  Alinamin is another form of thiamine.  It really is excellent at relieving my back pain from crushed vertebrae without side effects and no grogginess.   Look into the low histamine version of the Autoimmune Protocol Duet (Dr. Sarah Ballentyne, a Celiac herself, developed it.)  It really helps heal the intestines, too.  It's like a vacation for the digestive system.  Add foods back gradually over several weeks after feeling better.   I'm so happy to have pointed the way on your journey!  Let us know how the journey progresses! P. S. Add a Potassium supplement, too.  Potassium is another electrolyte, like magnessium, that we need.

      Hidden Gluten in distilled vinegar

      @knitty kitty I can't thank you enough!  My husband and I already started looking into those supplements.  We definitely plan to give it a try.  We've been against the Miralax since it was originally advised by PCP, but because of the level of pain she experienced on a daily basis, we decided to try it.  We've made many attempts to gradually decrease but due to her pain and related symptoms, we've kept her on it while trying all sorts of other dietary adjustments pre and post diagnosis specific to food; so far none of those efforts have made a significant difference.  I will definitely share how she's doing along the way!

      Opinions on my test results/symptoms

      By BIg Nodge · Posted

      Hi, I have recently embarked on the gluten-free journey. I have what to me seems like a somewhat confusing set of test results and symptoms. I have been impressed by the accumulated knowledge and thoughtfulness as I browse this forum, so I figured I'd make a post to see if anyone can offer any insight. I know there are many posts like this from new users, so I have tried to do my baseline research first and not ask super obvious questions.  I'm 43, overall very healthy. No history of gluten sensitivity or really any of the classic GI symptoms. About three years ago I started to experience intermittent bouts of fatigue, chills/cold intolerance, and shortness of breath/air hunger (sometimes feels like a hollowness in my chest, hard to describe). The symptoms over time have become fairly significant, though not debilitating, I am able to exercise regularly and am fairly physically active, continue to perform well at work. But for example I have gone from someone who consistently ran hot, was always cranking the a/c, to someone who wears a down vest inside at work in winter and get chills if the a/c even blows on me in summer. I get tired and lose energy even when getting decent amounts of sleep, and have to have my wife take over on long drives that I could previously handle with no problems. More generally when I am experiencing these symptoms they seem to crowd out space in my mind for focusing on my family, my hobbies/activities etc, I sort of withdraw into myself.   I happened to be experiencing these symptoms during an annual physical with my PCP a few years ago, he observed post nasal drip and suggested it was allergies and that I treat it with claritin. At first it seemed to respond to claritin (though not zyrtex), but over time I became unsatisfied with that answer. There didn't seem to be any seasonal rhyme or reason to my symptoms, and I felt like I was on an endless loop of taking claritin, then stopping, not being sure if it was even making a difference. I did eventually get allergy tests and found modest allergies to dust and pollen, which didn't feel like a smoking gun.  I then started seeing a natural medicine doctor who was much more willing to explore my symptoms via testing. The first thing that came back abnormal was elevated thyroid peroxidase antibodies/TPOs, 137 IU/mL vs a reference range of <9. At the same time my thyroid panel showed normal thyroid hormone levels. So it appears my immune system is attacking my thyroid even though it is working fine. I got a thyroid ultrasound at the time, it was clear, but with some abnormalities such that they suggested I get is scanned again in a year. These are certainly risk factors for a thyroid autoimmune disease, though my thyroid seems to be working fine for now.  From here my doctor considered celiac due to the murky thyroid/celiac links, so we did a panel. Results were as follows: TT IGA <1 U/ml, TT IGG <1 U/ml, deamidated gliadin IGA 24.6 U/ml, deamidated gliadin IGG <1 U/ml, IGAs 170 mg/dL. Readings greater than 15 considered high by my lab for the first four, my IGAs are within reference range. So basically just the deamidated IGA popped, but my IGAs are normal. I also notice on the tests that my thyroglobulin was high, 86.7 ng/ml vs a range of 2.8 - 40.9.  My doctor suggested that it certainly wasn't conclusive for celiac, but it was possible, and likely that I have some sort of gluten sensitivity. She suggested going gluten free and seeing how I felt as opposed to doing a biopsy. The best theory I can come up with is perhaps I am a silent celiac or just have a gluten sensitivity that doesn't produce immediate GI symptoms, but is still doing damage and over time has caused leaky gut. So now gluten is getting into my blood, and my immune system is attacking it but also mistakingly attacking my thyroid.  So that's what I did, went gluten free in October. It's been about four months, and I am really not feeling any difference. I still get the same symptoms that come and go. My bowel movements may be a bit more regular, but it was never a major issue before so I would consider that a minor improvement. I know that it can take a while to see improvements, and I am going to remain gluten-free and see how I feel. But I am definitely questioning whether I really understand what is going on, and am open to any thoughts or suggestions from the forum. Sometimes I wish I just went ahead with the biopsy before going gluten-free. While I would certainly be down to start drinking IPAs again ahead of a biopsy, you know, for science, I feel like at this point I would be throwing away four months of work and am better off staying the course and seeing what happens. But I'm really not sure.  I know there is a lot of thyroid knowledge on these boards, along with the celiac expertise, so I'm curious if this resonates with anyone's experience. And I'm interested in what sort of timelines people have experienced in terms of feeling improvements for some of these non-GI symptoms like chills, SOB, brain fog etc. Thanks in advance.

      Testing positive for antibodies, are there visible changes to the colon that could be seen without a biopsy?

      By cameo674 · Posted

      Does it taste like black licorice?  It said it was chewable.  I do not like that flavor.     Since the burn at the back of my throat is there everyday, I usually only take something when it is unbearable and keeping me from ADL especially sleep.

      Nandos improper preparion celiac childrens food

      By Scott Adams · Posted

      Your concerns about Nando's cross-contamination practices are valid and important for the celiac community. It's disappointing that Nando's does not have stricter protocols for children's portions, especially given the risk of cross-contact with gluten-containing items like garlic bread. Cooking gluten-free items on shared surfaces, even if cleaned, is not safe for individuals with celiac disease, as even trace amounts of gluten can cause harm. While the adult butterfly chicken may be a safer option, the inconsistency in practices for children's meals is concerning. It's frustrating that Nando's headquarters did not take responsibility, but sharing your experience raises awareness and may encourage them to improve their protocols. Consider reaching out to celiac advocacy organizations to amplify your concerns and push for better standards. Always double-check with staff and emphasize the importance of avoiding cross-contamination when dining out.
