Today I got my genetic testing back.

It shows category #4 DQ2 heterozygous. Related risk high. Though I see there is a Very High and Extremely High category, in addition to Moderate, Low, and Extremely Low.

Specifically, DQ2.5 (HLA DQA1*05:DQB1*201) are listed.

The only blood work that came back positive was the Anti-gliadin IGA, which was 24 on a range from 0-15.

Biopsy was done a few months before they were really looking for celiac so I don't know how many biopsies were taken, but they didn't show anything abnormal.

Yes, I have many symtoms but I also have sjogren's syndrome.

Have been trying to be gluten free but am still trying to work out things like shampoos, detergents, lotions, and the like. It will probably take awhile to get thing right.

I am not feeling at all better after a few weeks gluten free. In fact, I'd say that it feels like everything I eat makes me sick and I continue to lose weight.

Have pain in my arms and tingling in my face, legs, and feet.

Thoughts?

This is the most common celiac gene, also nicknamed HLA DQ2. (HLA DQ2,5)

You have only one copy of the DQ2,5 gene.

If you call the lab, they might have the result of the other gene (but it would not change things, since you already have the typical celiac gene)

Those genes are just about the risk, they do not mean you are celiac. Lots of people have HLA DQ2 and will never develop celiac disease.

The positive antigliadin IgA probably means it is early or patchy celiac, and with patchy celiac they might find a spot with celiac, or not, when taking biopsies.

Did they do the more specific deaminated gliadin test that many are getting now? It is much better at catching early celiac.

They did 4 different tests on blood work before the gene test. Here's what came back.

IMMUNOGLOBULIN A-SERUM normal range

GLIADIN ANTIBODY, IGA 24 (Abn: H) 0 - 15 is normal

GLIADIN ANTIBODY, IGG normal range

TISSUE TRANSGLUTAMINASE-A normal range

Annotation:

GLIADIN ANTIBODY, IGA

strict gluten free diet.

As stated, they would not do another endoscopy because they had done one 3 months earlier while checking for something else. From what I read on the biopsy report, lab only received 2 samples from the small intestines, which looked normal.

The only thing shown in the endoscopy was inflammation of the stomach. Colonoscopy showed 3 small diverticula.

Nurse for GI doc says go gluten free, regular GP says this really doesn't mean anything. It's very important to me, of course. My son came back with the same blood work, with an even higher Gliadin Antibody, IGA of 36.

Take all this paperwork to a new GI that specializes in Celiac disease.

There recently was a study trying to find out why one area in the U.S. had half as many positive biopsies compared to the other half of the country, and the difference was how many samples were taken.

Now the area where they took 4 or more samples while doing endoscopy, had twice as many diagnosed with celiac compared to where they only took about 2 samples.

I guess they missed your celiac, as the most common form of celiac nowadays is patchy celiac.

Also, the antigliadin test is known to rise first, and then the ttg, in early celiac.

I would guess that if you continue eating gluten, and even increase the gluten intake, then you will get a positive ttg test, and positive biopsies, after a month or two.

Things can change in a matter of a month or two or three.

But maybe the very specific deaminated gliadin test would tell you more beforehand, as it is very specific for celiac. If it is negative, it probably would not help to do another endoscopy yet.

(here in Europe we often do a gluten challenge to get a diagnosis, if the test results are dubious)

    • Yes I eliminated high glycemic foods. Eating only small amounts of carbs. No fruits, added sugars, starchy grains. Eating lots of fibrous veggies. Eating olive oil, as I don’t seem to tolerate the saturated fats or MCT oil. Allergic to nuts and seeds unfortunately.
    • Just wondering if you have an update at all? Going through the same thing at the the moment with my type 1 14 yr old. I would be interested to know what your gi said and how your daughters doing now? xx
    • Please check the date on post, you just responded and tried talking to a person from 7 years ago. On consideration to the subject Poatoes are a huge flare factor for my UC and cause my blood sugar to sky rocket...I am not even diabetic but for some reason potatoes (hash browns) that I tried a few months ago with some eggs shot it up over 400. not even a control test with table sugar managed that.
    • Have you tried eliminating high glycemic foods? Fruits, added sugars, starchy grains, potatoes. etc? Also adding in slow digesting fibers and fats can prevent insulin spikes, MCT oil is also known to help and protein. Many find consuming nuts and seeds higher in fiber early on in the meal or before a meal can slow down insulin responses and prevent spikes. I always tend to eat a hand full of whole shell pumpkin seeds, hemp seeds, cocoa nibs, etc. while fixing my food, this gets me starting to feel fuller sooner, and seems to help in over all down the road. I know I had some references somewhere to these. I know I read somewhere about the antioxidants in in whole shell seeds like pumpkin and hemp also helped the body regulate insulin levels.
    • Dear AWOL Cast Iron Stomach, Your husband is right bread is bad for you. Of course it's more than bread and gluten, until now it was amateur hour trying to self diagnose and tame this "lion". However they let you down. You slipped through the cracks over and over again it is not your fault your not the Dr. You made mistakes and errors acting like a celiac , not knowing for sure you were, and not feeling like you could fully claim to be or reach out for support . Now you know your husband was closer than any Dr. up until now to determine your illness. Now something is in your record, now hopefully you will be dismissed less,respected more, maybe they will realize its an actual condition going on- not all in your head. Will they? Who knows! Do you care? This is now official, now explained, you not only have to give up gluten, but milk, and corn. In fact give up 98% of processed anything. The cluster of lifetime symptoms were not  "just you", "in your head", "you are not a difficult patient", "when the Dr or nurse looks at you like a nut job you don't have to feel the dismissiveness and condescension. It's an illness and nothing to be shameful of  what is shameful is they and their colleagues missed you failed you. In fact being missed for 4 decades is unjust to you. You were missed time and time again from age 5 to 43, decade after decade after decade, symptom after symptom. It's not that you didn't try from the 5 year old begging to go to the Dr, to the 20 going to the hospital again for another bout of gastroenteritis hoping to get an IV, to the thirty year old saying something is wrong why is this happening, to the forty something a restaurant fed me gluten when I asked for gluten-free, I have been gluten free for 3 1/2 years ,  I have more symptoms and pain than before . I felt so good for those gluten-free years- please help me-make it stop. So many things explained it makes you experience a range of emotions. Grateful: Relief and gratefulness someone finally agreed to send you to someone to test you. She saw past the other diagnosis' and the albatross IBS diagnosis. All the ages and stages of symptoms are explained they all fit. Everyone of them! Someone else also has had them. You are not alone. Read the forum-you fit like a glove. Anger: Anger for the way you have been treated by the medical community, family, some ex boyfriends, friends and coworkers. Anger for the length of time you endured this. Hurt: Hurt for the times people said unkind things to you when you were symptomatic or flaring . you are experiencing symptoms that change your body people are rude to congratulate you on a "pregnancy" you didn't announce or ask why you are not slim when you hardly eat. you are not over emotional -  you are suffering from neuro symptoms, you are not making this up for attention Sad & Guilty: Can I work again? Do I want to work again? What kind of work can I do now? Can I find a job and work PT from home? You didn't envision this your husband having to be sole bread winner now what? I am overwhelmed thinking about this-stop? You now have closure and know how and why you lost your first pregnancy. You now know why you were high risk, complications,  with your children in Pregnancy & Delivery that they couldn't be explained back then It explains why in pregnancy you lost weight and why your morning sickness was extreme and seemed to last longer than anyone you knew,  that your Puppp rash was likely misdiagnosed DH It is not your fault none of it. Please forgive yourself for what you did not know. Your children forgive you. Believe them when they say its not your fault. You can cry, but you can no longer blame yourself. You are a good mother just one with an illness your children will learn to accept. Withdrawn: Why are you withdrawing from your husband? Should you ask him if he wants a divorce? Should you push him away? You didn't know before marriage what was happening you knew something autoimmune was brewing shortly after, but nothing showed on tests. Was this unfair to do to him? Doesn't he deserve someone better? Someone well? Now you can't retire and travel the world as society retirement cliché dictates. Can you afford this illness ? How will this financially impact your spouse, your family?. Why did you do this to this poor man? You are so selfish, you wanted marriage and kids, but was this fair to them? Don't your kids deserve a healthier mom? How will this impact them? Oh my gosh are they going to get this too? Will they grow to resent you? Your illness and diet has taken over their lives! Oh gosh no one say hi to me-please. I hate people and I am too sick to pretend and be fake friendly today. I don't want to tell you I am ill. I don't want to talk about this. I have to absorb this. I hate you people for being healthy. Don't tell me I don't look well. I will snap, I don't want to snap, I am irritable ,and don't feel well. Just keep giving off the unapproachable vibe keep them away.  Am I strong enough to do this? Acceptance: Calm down the inflammation, lack of nutrients, and GI damage is messing with your head. Your husband said for better for worse. Your kids have no choice you are their mother and you are a good mom -you have always been, always will be even on your worst day. If they get this they will be ok. You are strong enough to do this you are just ill and most importantly you must remain here in case they get this so you can guide them and be there for them. Got it? Go on the forum you are not alone it will be ok. You will get this lion back in the cage and manage it. It will be ok. If you can't travel in retirement one day you will find other hobbies or things to occupy your time. He's not going to leave you over this. If he does it will be ok. You'll manage-you always do. You have an answer, you knew it was coming, keep reading, learning, seeking support, and one day it will all work out. You will process all this and will be at peace-until then keep going and above all AVOID GLUTEN!
