Genetic Test Help?

Hi everybody,

Can we have Celiac or gluten intolerance with a negative genetic test? I don't know if it is possible. My biopsia didn't show Celiac , it came back showing gastritis. My dr also ordered a blood test, only one, and was negative. I don't know why he didn't order a complete Celiac panel. Anyway, I went gluten free after the biopsia and got a lot of better. After one month gluten free, my dr told me the tests were negative and to try gluten. I did, and after a few days I got diarrhea, bloating, abdominal pain and so tired. I am thinking to order the genetic test. Do you think it can be usefull in my case?

Thanks a lot for your time,

George.

Hi George,

Here is some information on gene testing:

Open Original Shared Link

Genetic testing for celiac disease

Celiac disease is a multigenic disorder associated with HLA-DQ2 (DQA1*05/DQB1*02) or DQ8 (DQA1*0301/DQB1*0302). HLA DQ2 is expressed in the majority (>90%) of those with celiac disease and DQ8 in about 8%. The expression of these HLA-DQ2 or DQ8 molecules is necessary but not sufficient to develop celiac disease and accounts for only about 50% of the genetic component of the disease. Studies in sibling (sib recurrence risk for celiac disease of 10%) [42] and of identical twins (concordance of 70%) [43] suggest that the contribution of HLA genes in celiac disease is less than 50%. The determination of the presence of HLA DQ2 or DQ8 is now available commercially. The role in the diagnosis of celiac disease is however limited because of the low specificity of the test for celiac disease. These HLA types are present in about 30% of the normal population. Their absence is useful in excluding celiac disease. The role in assessment of the presence of HLA DQ2 or is: 1. In the presence of an equivocal biopsy, 2. When someone is already on the diet, 3. To determine which family members should be screened for celiac disease.

Did they biopsy the small intestine(duodenum)? Gastritis is inflamation in the stomach.

      Anyone else get a lot of upper respiratory infections?

      Definitely worth speaking to your gastroenterologist about this. My own told me that by using Gaviscon a barrier forms over the contents of the stomach and stops gas and acid irritating the throat. In fact, he said to me that because I found relief using Gaviscon that was a very clear indicator that reflux was the cause of that particular issue. A wedge...

      Anyone else get a lot of upper respiratory infections?

      I did get the pneumonia vaccine about 4 years ago. I had this amazing allergist who did all those vitamin deficiencies test and told to get that vaccine. Unfortunately she retired. I haven’t been to an allergist in a few years, I’m not sure what my levels are now. I did have a pulmonologist who wasn’t concern and said I seemed fine to him that I was young...

      Yes I do have acid reflux. I’m not on anything for it at the moment. I sometimes wonder if that’s what it could be because I get heart burn every night. I may revisit my gastrointestinal doctor again. Thanks for the reply

      Anyone else get a lot of upper respiratory infections?

      Hi @HelloFlowersGoodbyeFlour I wonder if you suffer from reflux, as if you do, you may find it could also be irritating your airways. I shall explain: I have to use a blue inhaler from time to time, and it seems to be related to reflux. Never had any trouble before my coeliac diagnosis, the reflux seemed to be something that developed following...

      Since initially getting your D checked a few years ago, has it since rebounded to normal levels? Sounds like at some point you got it checked again.

I did have a pulmonologist who wasn’t concern and said I seemed fine to him that I was young etc. But yes I think I should at the very least get a different opinion. Thank you for your reply

      Hi @HelloFlowersGoodbyeFlour I wonder if you suffer from reflux, as if you do, you may find it could also be irritating your airways.  I shall explain: I have to use a blue inhaler from time to time, and it seems to be related to reflux.  Never had any trouble before my coeliac diagnosis, the reflux seemed to be something that developed following a holiday to France in 2019, where I had been exposed to gluten.    The reflux continued into the autumn and winter, my throat itched to begin with, particularly after meals, but it then that feeling of irritation seemed to spread to my lungs.  I even found it difficult to breathe on occasion. What stopped it in its tracks was using a wedge pillow at night, following a reflux diet (you can find them online), not eating 2-4 hours before bed and also having a dose of Gaviscon Advanced at night, which forms a barrier so that acid/food can't go back up your esophagus.  The throat irritation faded, and then I found it easier to breathe again. Just mentioning in case it could be a contributing factor.
