Dgp Iga And Other Diseases That Cause It To Be Positive

I was only positive on the deamidated gliadiin iga. I was told to go gluten-free and see how I do. I had no idea that getting an endoscopy was a big factor in diagnosing celiac. I went gluten-free for 9 months. I did great for about six months with no symptoms or pain. Then out of nowhere I started getting sick again. I never cheated on the diet, I didn't eat out and I only eat whole foods, nothing processed. I ended up getting a second opinion to another GI. He was arrogant, rude and didn't even examine me. My doctors office sent him my records from over a year ago and didn't include my celiac panel. I told him my results and he said "you don't have celiac, you need to be positive on the ttg test for you to have celiac." He pretty much rushed me out the door and didn't give me any advise on how to help me. I decided to go back to the clinic that ran the test , they have me setup for an endoscopy and colonoscopy for next week and I've been eating gluten again. I've been so sick for so long that I can't tell if it's the gluten or other foods making me sick. I hurt everywhere, I have shortness of breath, my pain radiates from my abdomen to my back (gallstones have been ruled out ). I feel like I'm crazy and nobody believes me. My family and doctors seem irritated when I talk about feeling sick because nothing is showing up on blood tests or ultrasounds. Here are my results for my celiac panel.

Deamidated gliadin pep ab igg -negative

Deamidated gliadin Pdp ab iga- positive - 18 flagged as high - reference range is 0.0-6.1 EUmL

Everything else was negative. They did the full celiac panel

What else would cause dgp to be positive.

Any info is much appreciated. Thanks

Welcome to the board.  :)

 

The DGP IgA is a really good test for detecting celiac disease. If you had a positive test, and feel better on the gluten-free diet, then I would say it is pretty much a sure thing that you have celiac disease. You don't need a positive tTG IgA to have celiac disease, nor do all celiacs have positive biopsies. That new doctor sounds like quite a dud.  :(

 

This site discusses the DGP test a bit:

Open Original Shared Link

 

This report has information on the DGP tests on pages 11 and 12. As you can see from the page 12 chart, the DGP IgA's specificity is 93-96%. That means that out of 100 positive tests, 4-8 do not have celiac disease and would not feel better on the gluten-free diet.

Open Original Shared Link

 

Have you had the DGP retested? It's one of the better tests for monitoring how well you are staying gluten-free. Gluten can slip in in spices, personal care products like soap, toothpaste or shampoo; or it could be in a product that is not made in a gluten free facility or contaminated bulk bin foods. Sometimes recipes change too. Some fries got me last year when their ingredients were changed.

 

Have your kidneys been checked? Pain that radiates to the back can sometimes be caused by kidney problems.

 

How about your thyroid? Thyroiditis is common among celiacs and can cause many symptoms that feel like a glutening.  To check your thyroid, request TSH (should be near a 1), free T4 and free T3 (should be in the upper half of the lab's normal range), and TPO Ab.

 

Best wishes. I hope you feel well soon.

I agree with nvsmom - sure looks like Celiac to me.  Just wanted to add - please don't get discouraged because you ran into a clueless doctor or two... there are idiots in the doctor population just like everywhere else.  And being that there is no prescription for them to write in response to Celiac I really think some of them just don't care to educate themselves about it.  But there are doctors out there who do care and are knowledgeable and who won't treat you like you're crazy.  Sometimes they can be hard to find.

 

In my opinion, based on the test results you posted, you have Celiac.  You're either running into cross-contamination issues or there's hidden gluten in something that you're eating - or there is also something else going on not related to gluten.  Recheck all the labels, as companies change their recipes.  (A common theme on here is ... every label, every time.)  Check your vitamins and any medications too. 

I do however, think that it's good that you're double checking to make sure the pain you're having isn't attributed to something else, potentially more serious.  I think there is a tendency for Celiacs to blame everything on gluten... and sometimes we get sick with other stuff just like everyone else.

Thanks for the replies!! I will know more on Wednesday after my endo/colonoscopy. I was talking with a friend who is a nurse and she mentioned hiatal hernia as possibility. It really makes me wonder. Wish me luck! I'm a little nervous about the colonoscopy prep :/

You will do just fine. Just drink all the fluids as recommend, to prevent dehydration.

I also had one test that came back positive, which the deamidated gliadin IgG portion of the test. My labs were also sent to a gastro doc who also was very rude, said that I didn't have it at all and scoffed when he heard me say that I felt better going gluten free. I did end up finding out a month later after the celiac test came back positive that I have a milk allergy. I didn't feel completely better and when I found that out I went gluten and dairy free. That really made me feel so much better. I would go through with the colonoscopy and endoscopy but you may want to go to an allergist just to rule out any other allergies. You probably don't have any but it is better safe than sorry.

      Shingles - Could It Be Related to Gluten/ Celiac

      My understanding, and ex I erience is that we coeliacs are likely to suffer more extreme reactions from viruses. Eg we are more likely to be hospitalised with influenza. So, sadly, your shingles may be worse because you are coeliac. So sorry you had to go through this. My mother endured shingles multiple times. She was undiagnosed with coeliac disease until...

I was training heavily for cycling for a few weeks prior to the onset of these symptoms starting. I have had low Ferratin for about 4 years (started at 6) and usually sits around 24 give or take. I was...

      Cold/flu or gluten poisoning?

      Cold/flu or gluten poisoning? Hello. I've had another similar episode. I find it very difficult to differentiate between the symptoms of a cold or flu and those caused by gluten poisoning. In fact, I don't know if my current worsening is due to having eaten something that disagreed with me or if the cold I have has caused my body, which is hypersensitive...

      Celiac disease symptoms

      I'm no longer dealing with constipation. I got my liver test last month and it was in normal range. Two years ago I did have a vitamin D deficiency but I'm know taking vitamin D3 pills. Last month I got my vitamin D checked and it was in normal range. I don't believe I've had my choline checked. However, I do drink almond milk eat Greek yogurt on a daily...

      Non-Celiac Gluten Sensitivity (NCGS) can be associated with low ferritin and iron deficiency. Once Celiac Disease (1% of the population affected) has been ruled out by tests the next step is to check for Non Celiac Gluten Sensitivity (10% of the population affected) by eliminating gluten for a trial period, then re-introduce Gluten Challange.

      Hi all,  Looking for some advice. I started having some symptoms this past summer like night sweats and waking at 4 am and felt quite achy in my joints. I was training heavily for cycling for a few weeks prior to the onset of these symptoms starting. I have had low Ferratin for about 4 years (started at 6) and usually sits around 24 give or take. I was doing some research and questioned either or not I might have celiac disease (since I didn’t have any gastric symptoms really). My family doctor ran blood screening for celiac. And my results came back: Tissue Transglutaminase Ab IgA HI 66.6 U/mL Immunoglobulin IgA 1.73 g/ My doctor then diagnosed me with celiac and I have now been gluten free for 3 months. In this time I no longer get night sweats my joint pain is gone and I’m still having trouble sleeping but could very much be from anxiety. I was since referred to an endoscopy clinic to get a colonoscopy and they said I should be getting a biopsy done to confirm celiac. In this case I have to return to eating gluten for 4-6 weeks before the procedure. Just wanted some advice on this. I seem to be getting different answers from my family physician and from the GI doctor for a diagnosis.    Thanks,

      Non-Celiac Gluten Sensitivity (NCGS) can be associated with low ferritin and iron deficiency. Once Celiac Disease (1% of the population affected) has been ruled out by tests the next step is to check for Non Celiac Gluten Sensitivity (10% of the population affected) by eliminating gluten for a trial period, then re-introduce Gluten Challange. Have you been supplementing Iron? How are your liver enzymes? Low levels of ferritin indicate iron deficiency, while  59% transferrin saturation indicates high iron levels.  Possibly indicating Fatty Liver Disease.  Choline is crucial for liver health, and deficiency is a known trigger for Non-Alcoholic Fatty Liver.  Some experts say that less than 10% eat the the Food and Nutrition Board established Adequate Intake that are based on the prevention of liver damage. Severe constipation and hemorrhoids may be linked to a bile or choline deficiency.  "Ninety-five percent of phospholipids (PLs) in bile is secreted as phosphatidylcholine or lecithin."  Fatty acid composition of phospholipids in bile in man   Deficiency of these bile salts causes the bile to get thick. Some people with Celiac Disease are misdiagnosed with Gall Bladder bile issues.  Removal of the gallbladder provides only temporary relief. Whether or not celiac disease or NCGS are your issues you need to look at your vitamin D blood level.
