One Celiac Gene and Positive DGP-IGG


FiveApples

Recommended Posts

FiveApples Newbie

TLDR - I have one celiac gene variant - HLA-DQA1 and my DGP-IGG was elevated (11.2149U/mL). However, none of the other antibodies (ttg iga - 1.7, ttg igg - 3.3 , dgp iga - 4.1) were elevated. What's that mean?

Hey guys, my digestive issues have been going on for years and have been largely ignored before this past year when silent reflux burned my esophagus to the point that I could no longer swallow pills or many foods. An ENT said I needed a battery of tests after looking in my throat, then never called to schedule them, presumably because covid locked down hospitals for anything but life-death situations for a while. Though she also didn't even manage to get a non-pill-form omeprazole to the pharmacy for me like she said she would and never returned my phonecalls about it. I was left with the option of paying an arm and a leg for the prescription of buying otc and crushing when it should have been a free prescription with my insurance if she'd just entered the right one. Obviously not going back to Dr. Idiot. 

I got the reflux under control myself after a couple of months (reduced coffee, dairy, gluten), then started doing at home tests to try and figure out the root issue. To be clear, I've been asking doctors what could be wrong with my digestive system since I was 13, I am now 31, and they've run minimal tests related to digestion. I got diagnosed with gastroparesis some years ago but it only seems to happen when I eat too many eggs so that doesn't really seem like an issue. I've had low bmi all of my life, I'm always vitamin deficient, I'm always exhausted, no matter how healthy I eat. I'm also always hungry despite eating near 4k cals a day with minimal exercise. Not just like a little hungry, I feel insatiable all the time, even if it's only been an hour since I last ate. I'm 5'3" and 94-96lbs. I have idiopathic nerve damage diagnosed through a punch biopsy and had POTS prior to supplementing iodine. 

Anyway, the home tests. I have one celiac gene variant - HLA-DQA1 and my DGP-IGG was elevated (11.2149U/mL). However, none of the other antibodies (ttg iga - 1.7, ttg igg - 3.3 , dgp iga - 4.1) were elevated. 

I know I should go to a doctor and ask, but honestly I'm so fed up with them that I'd rather eat lead. I'm tired of them trying to tell me I need to eat more cause they think I'm a lying anorexic. I'm tired of them telling me my weight's not a big deal when I can see every one of my ribs. I'm tired of it being crystal clear that there's something very wrong with me and them acting like everything's fine. I'm just tired of them. So, I would like opinions, are the two tests above enough to conclude that I have celiac? It doesn't seem like much. And aside from giving me a diagnosis stamp, is there anything else a doctor would even be able to do about celiac if that's what this is? Isn't the treatment just... no more gluten? Is there another test they would have me do if I went to see a doc?

Oh, and my maternal aunt was diagnosed with celiac at some point if that matters. I don't talk to her enough to feel comfortable asking her about it.

Welcome to the forum, FiveApples!

You said: "I got the reflux under control myself after a couple of months (reduced coffee, dairy, gluten), then started doing at home tests to try and figure out the root issue. "

By reducing your gluten intake before you did the antibody testing you likely sabotaged the results. Also, when you post antibody test numbers on the forum, please include the reference ranges for negative vs. positive. Those are not industry standards. They vary from lab to lab.

Thank you! Unfortunately, I had to do something to alleviate symptoms as I couldn't sleep through the night even with a wedge and a special pillow. The testing kit I ordered said it would still be accurate as long as I continued to eat small amounts of gluten daily, which I did. So maybe they were still somewhat accurate?

The Mayo Clinic recommendation for a pretest gluten challenge is two slices of wheat bread (or the equivalent) daily for 6-8 weeks leading up to the day of antibody testing.

It is also possible that you have NCGS (Non Celiac Gluten Sensitivity). It shares many of the same symptoms with celiac disease but does not damage the small bowel villi and so, does not produce antibodies. There currently is no test for NCGS. Celiac disease must first be ruled out.

To me it sounds like you've already identified wheat as a culprit for some or all of your symptoms. You could do a gluten challenge as @trents mentioned and get another blood panel done, or your could just go gluten-free. If your aunt has it your odds of having it are higher, and you already know that you have the genetic markers that make celiac disease a possibility for you. If giving up gluten for life is too big of a prospect for you to consider without a formal diagnosis, then I'd encourage you to get retested.

Also, given that it looks like you had one positive blood test for celiac disease, your doctor may want to schedule an endoscopy, and if so, you'd only need to eat wheat daily for 2 weeks beforehand.

I definitely don't think I was eating that much most days (though some I ate more). Can high dpg-igg be present without any kind of wheat thing going on?

At this point it seems like I may as well just quit gluten for a while and see what happens. If it fixes the issues I can commit. I really don't want to go back to a doctor. I feel more than a little resentful about how they dismissed my issues until things were completely out of control. Thank you!

This might be helpful in understanding the several dimensions of eliminating gluten from your life. And I want to say it's not about cutting way down on gluten, it's all about eliminating it altogether. Even small amounts of gluten can keep the fire smoldering: 

Also be aware that those with gluten sensitivity issues are frequently intolerant to other foods. Common among them are dairy, oats and eggs. So, you might want to keep a food diary so as to spot patterns between your symptoms and what you have been eating. There can be a delay of 24 hr. or more between the consumption of an offending food and the experiencing of symptoms.

I am pretty sure that the dpg-igg test is fairly specific for gluten, but it is the best test to use in those 7 years old or younger:

https://pubmed.ncbi.nlm.nih.gov/22197936/ 

It's possible that it is a false positive test, but unlikely I think.

Or IGA deficient adults. https://pubmed.ncbi.nlm.nih.gov/22197936/ It is very specific for celiac disease.

Honestly, I would probably get an official diagnosis if you can, even if it means switching doctors - you may be able to find a celiac-aware doctor in your area on this forum or others. Bringing a support person to your appointment may get them to take you more seriously. Also, be sure to note your family history of celiac.

Yes, the treatment is just no more gluten, but if it is celiac follow-up care should be performed (which should be covered by your insurance if you have an official diagnosis). You can certainly pay for your own bloodwork/nutrient testing out-of-pocket thru labs like Ulta Lab Tests, but it does get costly. But repeat biopsies and bone mineral density (which really should be done) would have to go thru a doc.

Also, in the future things such as dietary needs for a hospital stay may be taken more seriously if it is "official". Since celiac is an autoimmune disease, you would be at higher risk for developing other autoimmune diseases. And if you have any kids now or in the future, they should be tested (as well as other biological relatives), as they would have a greater change of having celiac too.

https://www.beyondceliac.org/living-with-celiac-disease/talking-to-your-family/getting-the-conversation-started/family-testing/#:~:text=Remember that celiac disease can,or sooner if symptoms develop.

Here are a couple of links to good overviews of the various celiac tests:

https://celiac.org/about-celiac-disease/screening-and-diagnosis/screening/

https://www.beyondceliac.org/celiac-disease/get-tested/

It took me quite a while to not have insatiable hunger as you describe after dropping gluten and adding vitamin supplements to get my nutrient levels into an ideal range (still working on a couple) - I had to eventually go dairy-free also. Abnormal hunger did eventually diminish though (over years, not months).

Additionally, here is a link about the DGP-IgG test:

"A positive test result means that it's likely you have celiac disease."

https://www.urmc.rochester.edu/encyclopedia/content.aspx?contenttypeid=167&contentid=dgp_celiac_disease

It does not look like a total IgA level was measured in the bloodwork you had done? This is usually included in the celiac panel because if a person is IgA deficient, the IgA tests will be invalid (in which case they would look at IgG or  other tests for diagnosis).

      So I recently had allergy testing for IGE antibodies in response to foods. My test results came back positive to corn, white potatoes, egg whites. Tomatoes, almonds and peanuts to name a few.  I have had obvious reactions to a few of these - particularly tomatoes and corn- both GI issues. I don’t really understand all this allergy versus celiac stuff. If the food allergies are mild do I have to avoid these foods entirely? I don’t know what I will eat if I can’t  have corn based gluten free products

      Geography makes a difference.  I'm in the West and Trader Joe's gluten-free bread tastes great and is a better price than most gluten-free breads sold elsewhere in my area.

      We have four children (7-14 yo), and our 7 year old was diagnosed with NCGS (though all Celiac labs were positive, her scope at 4 years old was negative so docs in the US won't call it celiac). We have started her on a Gluten Free diet after 3 years of major digestive issues and ruling out just about everything under the sun. Our home and kitchen and myself are all gluten-free. But I have not asked my husband/her dad or her other siblings to go completely gluten-free with us. They are at home, but not out of the home. This has led to situations when we are eating out where she has to consistently see others eating things she can't have and she has begun to say "Well, I can't have <fill in the blank>...stupid gluten."  How have you supported your gluten-free kiddos in the mental health space of this journey, especially young ones like her. I know it's hard for me as an adult sometimes to miss out, so I can't imagine being 7 and dealing with it! Any tips or ideas to help with this?

      By the time I was 5 I had my first auto0immune disorder, Migraine headaches, with auras to blind me, and vomiting, sensitivity to light and sound. I was 5 years old, and my stepfather would have pizza night, milling his own flour, making thick cheesy gluten pizza, that I would eat and the next day, I would have serious migraines, and my mother & stepfather did nothing about my medical problems. When I was 17 in my first year at college, I was diagnosed with my 2nd known auto-immune disorder, Meniere's disease. I was a elite athlete, a swimmer, and soccer player. And once again my parents didn't think anything of understanding why I had a disorder only older people get. Now after my mother passed from Alzheimer's disease she also suffered with living with gluten. She had a rash for 30 years that nobody could diagnose. She was itchy for 45 years total. My brother had a encapsulated virus explodes in his spleen and when this happened his entire intestines were covered with adhesions, scar tissue and he almost lost his life. He has 5 daughters, and when I finally was diagnosed after being pregnant and my body went into a cytokine storm, I lost my chance to have children, I ended up having Hashimoto's disease, Degenerative Disc disease, and my body started to shut down during my first trimester. I am 6ft tall and got down to 119lbs. My husband and I went to a special immunologist in Terrace, California. They took 17 vials of blood as we flew there for a day and returned home that evening. In 3 weeks, we had the answer, I have Celiac disease. Once this was known, only my father and husband made efforts to change their way of feeding me. At the family cabin, my stepfather & mother were more worried that I would ruin Thanksgiving Dinner. It wasn't until one of my cousins was diagnosed with Celiac disease. They finally looked into getting Gluten Free flour and taking measures to limit "gluten" in meals. He did nothing but ask for me to pay for my own food and wi-fi when I came to the cabin to stay after our house burned down. When he informed my mother, they proceeding to get into a physical fight and she ended up with a black eye. The is just more trauma for me. Sam had no interest in telling the truth about what he wanted. He lied to my mother that he had asked my husband if I could pay for "food" when he asked Geoffrey if I had money to pay for my wi-fi. My mother hates when he spends so much time on the computer so he lied and said I could pay for my own food. I will remind you I weighed 119lbs at this time. (At 6ft) that is a very sick looking person. Neither parent was worried about my weight, they just fought about how cheap my stepfather was. As my mother was diagnosed with Alzheimer's disease in 2014. He had her sign over the will to a trust and added his children. He had no testimonial capacity at the time, so she signed without proper papers. Making this Trust null and void. When I gave my brother my childhood home, my mother stated I would be getting an equal part of inheritance to the house on Race. It currently worth 2.0 million $. I got nothing, and my stepfather has since disowned me b/c of my claim and he knows that my mother would never have left it uneven between my biological brother and myself. She sat me and my husband down, as we lived at the Race Street house and treated and took care of it as our own. My brother took over b/c he was going through a horrific divorce and needed a home so he could get a better custody deal with his soon to be ex-wife who was a Assist DA for Denver. She used the girls against him, and he & I were the primary caregivers. We, Judd and I spent the most time with them pre the divorce. Once Judd moved into the house, he threw all of my mother, grandmother and my family heirlooms out to the Goodwill. Nobody told my mother about this as she was going through cancer treatment and had Alzheimer's disease in her mother and her sister. My stepfather and biological brother took advantage of this matter, as I called a "family council" that my brother just never could make it to at the last moment. All of the furnishing, kitchen ware, everything was in the house my brother just moved into. He had had 2 weddings, I chose to elope b/c my stepfather ruined my brother's first wedding by talking about his relationship with my brother in front of my dad and his entire family, insulting him and having my grandfather leave the ceremony. It was a disaster. My stepfather just plays dumb and blames my father for the slight. I was the only child not to have a wedding. So, my mother and stepfather never had to pay for a thing. My mother had had an agreement with my father he'd pay for college and all medical issues with their kids, myself and Judd. So truly my mother never had to pay for anything big for me in her entire life. I am looking for anyone that has had a similar story, where they grew up in a household that had a baker that regularly milled flour and ate gluten. What happened to you? DId you suffer from different auto-immune diseases b/c of living with a baker using "gluten" Please let me know. I have been looking into legal ways to get my stepfather to give me what my mother had promised, and he erased. Thank you for listening to my story. Jane Donnelly

      Possibly gluten withdrawal. Lot's of info on the internet about it. Somewhat controversial but apparently gluten plugs into the same neuro sensors as opiates do and some people get a similar type withdrawal as they do when quitting opiates. Another issue is that gluten-free facsimile flours are not fortified with vitamins and minerals as is wheat flour (in the U.S. at least) so when the switch is made to gluten-free facsimile foods, especially if a lot of processed gluten-free foods are being used as substitutes, vitamin and mineral deficiencies can result. There is also the possibility that she has picked up a virus or some but that is totally unrelated to going gluten-free.
