genetic tests

Hello,

I was here a bit  in October when I was confused about some symptoms I was experiencing.  I thought maybe Celiac, but hoped not.  My doctor ran a celiac panel, which I realize now wasn't a full panel, she ran 3 tests, which were negative.  She told me that I could still have Celiac and sent me to a GI doctor for a consult.  I was happy the day I got my results and started thinking that my symptoms were in my head.  I thought about not going to the GI appointment and seeing how I felt, then I got this terrible rash that I get from time to time, super itchy, yet burns when you touch it, it keeps me up at night.  I did a little research and realized it could be DH and decided to keep my appointment with the GI doctor.

The GI doctor was awesome, very willing to listen to my concerns.  She is going to do an EGD with biopsies and a colonscopy (what triggered this was treatment resistent iron deficiency anemia).  I also have autoimmune hepatitis and a hiatal hernia so she feels like even if I don't have celiac, she still wants to take a look at things.  She tossed around things like FODMAP, wheat allergy, eosinophil esophagus.  She suggested a genetic test for celiac, she said if it was postitive it meant that I had the genetic potential to develop celiac and if it was negative that I didn't have the genetic potential to develop it.  I looked at my results and some are postitive and some are negative.  I realize that only one needs to be positive, but I was unsure about the numbers, does anyone know what this means?

I thought I could paste a snip but I can't... ugh

HLA DQ2 Negative

HLA DQ8 Positive

HLA DQA1* 03

HLA DQB1* 0302

HLA DQB1* 0301

HLA Variants detected: HLA DQA1* 03

I'm glad she did this test, I can make sure she follows the proper recommmendations for the number/locations of biopsies.  I'm not getting the procedures done until January 8, I don't want to meet the deductible of my high deductible insurance in December, then have to meet it again next year since we are so close to the end of the year.

I'm not sure if I've offended someone, or if nobody comes around these parts, but I feel kind of snubbed.  Maybe there's a different forum where people are active?  I did a search of these forums for what I'm looking for, but I haven't found it on this site.  I'm sorry if I'm annoying for asking the same question that has been asked before, but I thought this was a support forum, where people supported each other, I can find info and try to decipher it on my own, but I came here to talk it out with people who have been through this.

Hi Cheryl,

Im sorry that you feel snubbed... (hugs).  This board has been quiet lately for sure.  I don't know why...holidays?  But I don't think you've said anything offensive.   Would your GI be willing to run the remaining celiac tests?  That would be less expensive than the endoscopy.  I didn't have any genetic testing done so I can't answer anything related to that.  I do know that if it is DH  that you need a biopsy of the skin next to the rash and that can confirm a diagnosis without an endoscopy.  I hope that you get the help and answers that you need.

Cheryl, 

I am sorry that you feel snubbed!  It has been a little slow lately and that seems to be the nature of forums!  Folks get busy or well!  Anyway, I do not have any expertise on genetic testing or DH (celiac disease rash), so that is why I did not respond.  I do know that if you look through the DH section, it can be more difficult to diagnose.  Blood tests can be negative if I recall.  Skin biopsies are really tricky.  Please research DH so that you are knowledgeable and can discuss it with your doctor.  

Remember that the genetic tests are just a tool that has been normally used to rule out celiac disease.  But the latest research shows that there are other genes involved depending on where you live in the world.  

It sounds like you have good doctors.   That is a relief!  With your autoimmine hepatitis and anemia, it sounds like you have celiac disease.   Something is wrong!

Hang in there!

Sorry you feel snubbed.  My laptop died, so I jumped on someone elses computer today.

I am not a full believer in genetic testing as the end all definitive answer.  My family went through the genetic testing and had some questionable results.  I questioned the results and was told by Prometheus labs... Genes can mutate, there is still the 2% known miss rate, and all blood tests have a 30% human error rate.

You might want to look at some information on Pernicious anemia. 

Good luck on your testing.  Please keep us updated on your progress and ask any questions you would like.

There is also the gluten files Celiac group forum that gets very technical.  I think they are still running strong, but I prefer this group.  It seems a lot of our group got very personal and linked up with each other on facebook and such.

Hi CherylS!   Please don't feel slighted!  I'm sure plenty of us have read your post but didn't feel we had anything to help you.  Your situation is fairly complex and I don't share your issues.  Luckily, it does sound like you have good doctors--a HUGE advantage.

I imagine somebody with DH will respond and give you some tips about that.  There is lots of help here and lots of people who are very caring and kind.

Hang around and hang in there!  Best of luck!

Hi Cheryl,

Since you are still in the testing phase, be sure to keep eating gluten for now.  The antibodies that cause celiac damage decline after we stop eating gluten and are harder or impossible to detect after a while.  The IgA antibodies (DH) are deposited in the skin and blood tests don't include skin samples.  That's why they take a sample of skin next to a DH lesion when testing for antibodies.

I suppose you have heard of Hashimoto's Thyroiditis?  I see your interests include Grave's disease.  They test for Hashimoto's by testing for TPO antibodies.  Hashimoto's attacks the thyroid and can cause symptoms to swing between hyper and hypo thyroid.

There is a positive relationship between celiac disease and other auto-immune conditions.  It's not super unusual for people to have more than one auto-immune disease.  Some people say auto-immune diseases run in packs.

Later...

      Thank you for the clarification and for taking the time to explain the terminology so clearly. I really appreciate your insight, especially the distinction between celiac disease and NCGS and how anemia can point more toward celiac. This was very helpful for me.

      Son's legs shaking

      Hi, My 7 year daughter has complained of this in the past, which I thought were part of her glutening symptom, but more recently I have come to figure out it's part of her histamine overload symptom. This one symptom was part of her broader profile, which included irritability, extreme hunger, confusion, post-nasal drip. You might want to look up "histamine...

      Son's legs shaking

      My 5yo was diagnosed with celiac last year by being tested after his sister was diagnosed. We are very strict on the gluten-free diet, but unsure what his reactions are as he was diagnosed without many symptoms other than low ferritin. He had a school party where his teacher made gluten-free gingerbread men. I almost said no because she made it in her...

      Bob red mill gluten free oats

      Not necessarily. The "Gluten Free" label means not more than 20ppm of gluten in the product which is often not enough for super sensitive celiacs. You would need to be looking for "Certified Gluten Free" (GFCO endorsed) which means no more than 10ppm of gluten. Having said that, "Gluten Free" doesn't mean that there will necessarily be more gluten than "Certified...

      High TTG-IgG and Normal TTG-IgA

      By trents · Posted

      Currently, there are no tests for NCGS. Celiac disease must first be ruled out and we do have testing for celiac disease. There are two primary test modalities for diagnosing celiac disease. One involves checking for antibodies in the blood. For the person with celiac disease, when gluten is ingested, it produces an autoimmune response in the lining of the small bowel which generates specific kinds of antibodies. Some people are IGA deficient and such that the IGA antibody tests done for celiac disease will have skewed results and cannot be trusted. In that case, there are IGG tests that can be ordered though, they aren't quite as specific for celiac disease as the IGA tests. But the possibility of IGA deficiency is why a "total IGA" test should always be ordered along with the TTG-IGA. The other modality is an endoscopy (scoping of the upper GI track) with a biopsy of the small bowel lining. The aforementioned autoimmune response produces inflammation in the small bowel lining which, over time, damages the structure of the lining. The biopsy is sent to a lab and microscopically analyzed for signs of this damage. If the damage is severe enough, it can often be spotted during the scoping itself. The endoscopy/biopsy is used as confirmation when the antibody results are positive, since there is a small chance that elevated antibody test scores can be caused by things other than celiac disease, particularly when the antibody test numbers are not particularly high. If the antibody test numbers are 10x normal or higher, physicians will sometimes declare an official diagnosis of celiac disease without an endoscopy/biopsy, particularly in the U.K. Some practitioners use stool tests to detect celiac disease but this modality is not widely recognized in the medical community as valid. Both celiac testing modalities outlined above require that you have been consuming generous amounts of gluten for weeks/months ahead of time. Many people make the mistake of experimenting with the gluten free diet or even reducing their gluten intake prior to testing. By doing so, they invalidate the testing because antibodies stop being produced, disappear from the blood and the lining of the small bowel begins to heal. So, then they are stuck in no man's land, wondering if they have celiac disease or NCGS. To resume gluten consumption, i.e., to undertake a "gluten challenge" is out of the question because their reaction to gluten is so strong that it would endanger their health. The lining of the small bowel is the place where all of the nutrition in the food we consume is absorbed. This lining is made up of billions of microscopically tiny fingerlike projections that create a tremendous nutrient absorption surface area. The inflammation caused by celiac disease wears down these fingers and greatly reduces the surface area needed for nutrient absorption. Thus, people with celiac disease often develop iron deficiency anemia and a host of other vitamin and mineral deficiencies. It is likely that many more people who have issues with gluten suffer from NCGS than from celiac disease. We actually know much more about the mechanism of celiac disease than we do about NCGS but some experts believe NCGS can transition into celiac disease.

This one symptom was part of her broader profile, which included irritability, extreme hunger, confusion, post-nasal drip. You might want to look up "histamine intolerance". I wish I had known of this at the time of her diagnosis, life would have been much easier.  I hope you are able to figure out.

We are very strict on the gluten-free diet, but unsure what his reactions are as he was diagnosed without many symptoms other than low ferritin.  He had a school party where his teacher made gluten-free gingerbread men. I almost said no because she made it in her kitchen but I thought it would be ok.  Next day and for a few after his behavior is awful. Hitting, rude, disrespectful. Mainly he kept saying his legs were shaking. Is this a gluten exposure symptom that anyone else gets? Also the bad behavior?
