Grrrr Gene Testing-Results Not What I Expected

so i already felt in the grey area with testing, please see my signature, and was hoping for some validation with genetic testing.  That didn't come through since it showed I don't possess DQ2 or DQ8, but instead have gluten sensitive genes which I know aren't medically backed anyway  :(

 

Here were my results:

 

Gluten Sensitivity Gene Test

HLA-DQB1 Molecular analysis, Allele 1      0303   

HLA-DQB1 Molecular analysis, Allele 2      0501   

Serologic equivalent: HLA-DQ   3,1  (Subtype 9,5)


 

TEST INTERPRETATION(S):

Interpretation of HLA-DQ Testing:  Although you do not possess the HLA-DQB1 genes predisposing to celiac disease (HLA-DQ2 or HLA-DQ8), HLA gene analysis reveals that you have two copies of a gene that predisposes to non-celiac gluten sensitivity, in your case HLA-DQB1*0303 and HLA-DQB1*0501. Having two copies of a gluten sensitive gene means that each of your parents and all of your children (if you have them) will possess at least one copy of the gene. Two copies also means there is an even stronger predisposition to gluten sensitivity than having one gene, and the resultant immunologic gluten sensitivity may be more severe. This test was developed and its performance characteristics determined by the American Red Cross - Northeast Division. It has not been cleared or approved by the U.S. Food and Drug Administration.

Hon, I am sorry, I have looked and looked, but I cannot  find any Pub Med, scientific or informational research that corroborates any 

 

 

" gene that predisposes to non-celiac gluten sensitivity"

 

 

But this does not exclude a NCGS diagnosis.!..if gluten makes you sick, you have a gluten intolerance

and should stay gluten-free.

IMHO  ( I am not a doctor) 

 

"Currently, there are no recommended methods to test for non-celiac gluten sensitivity. Some doctors offer saliva, blood or stool testing. However, these tests have not been validated and are therefore not accepted.  

In NFCA’s webcast, Dr. Guandalini states:

“As a matter of fact, right now, they are to say that there is absolutely no biological readout that is no way can this diagnosis can be supported by any laboratory investigation. No antibodies in the blood are specific enough, or sensitive enough, for this condition. No antibodies in the stools can be utilized to diagnose or screen for this condition.”

Dr. Fasano also touched on this topic and stated that his team is currently conducting research to identify biomarkers that may help to test for and diagnose non-celiac gluten sensitivity:

“…as Dr. Guandalini explained when the only way to make a diagnosis of gluten sensitivity is by exclusionary criteria since we do not have tests that will point in that direction. And that’s where our current efforts are all about. Now that we understand that it is a different entity we want to make sure that we can eventually identify the biomarkers for this condition, and we’re doing a double blind study to identify the biomarkers that will eventually fill the gap that Dr. Guandalini was alluding to.”

I agree with Irish.  You have seen that I have harped about the fact that although I have been formally diagnosed, my husband has not.  He's been gluten-free for 13 years.  He went off gluten at the advice of my allergist and his GP.  It would be nice to have a formal diagnosis, but he has stated that he will not do a gluten challenge.  For what? He already knows that gluten makes him sick.

Oh gee, I know you were hoping for a more definite result.  :(  I've never heard anything about gluten sensitivity genes either.

 

You could be in that minority of celiacs who do not have the DQ2 or DQ8 genes. I read (in Dangerous Grains I believe) that 90 and 94% of celiacs have the DQ2 and DQ8 genes respectively. There are a couple of people around here who are in the same boat - I just can't remember who...

 

The gold standard biopsy after a positive blood test seems like a bit of a crap shoot to me; I'm exaggerating a bit but I don't understand why doctors love it so much. They already had a positive test showing that your body is attempting to do damage when gliadin is in your system, just because they did't find damage doen't mean your body is trying to attack itself. They can miss finding the damage or perhaps your body is withstanding the autoimmune attack better than others do. Who knows... That was part of the reason I did not have the biopsy, I didn't want an ambiguous test to affect my resolve to live gluten-free.

 

You've had positive blood tests, you feel better gluten-free, and your health has improved. It's celiac disease. I've never found anything else that causes a high DGP. The grey area you are in is almost black. KWIM? You are making yourself better, just stick with it and let doctors call it whatever they want.

Not all celiacs have DQ1 or DQ2.  I myself am a firmly diagnosed celiac who is a double DQ9 and was close to death by the time I was diagnosed.  I have a family member who was diagnosed by both blood test and biopsy who recovered on the diet but then was gene tested a few years later and told they were not celiac because they also didn't  have DQ2 or DQ8. There is still much to learn about genes and if you have had some positive blood work that has gone into normal ranges and you have seen relief on the diet IMHO you are celiac. Continue healing and don't worry about what label under which you fall.

all your replies definitely made me feel better :)

 

I was upset when I wrote the first post, there's no denying that, but despite those results it doesn't change that gluten makes me feel terrible.  It brings my digestion to a halt and the brain fog makes me feel like I'm having an out of body experience.  I'm there physically, but mentally I'm so out of it, I'm not fit to be around.  I even thought about the way I would have reacted pre-gluten-free to the test results.  I would have been upset for days at the outcome.  I'm still a bit disappointed, but it's nothing that compares to the fantastic way I've been feeling...minus the post I made the other week about finally trying oats again and reacting to them. 

 

This whole process has been so frustrating, but in the end I realize I should count myself lucky that LabCorp even runs DGP tests as part of their panel, or I would still be wondering what is wrong with me.  The only thing that makes this process less frustrating is coming here to vent and having others truly understand :)

 

Things I've decided:

-I'll stop chasing the celiac diagnosis because without DQ2 or DQ8, this country won't recognize it anyway.  Maybe in the future those genes will change, but right now it is what it is.

-When people ask me why I can't eat something with gluten, I'm still going to say that I tested positive for celiac disease.  They don't need to know which test.

-I really liked Melinda Dennis' idea of saying to a server at a restaurant that I follow a medically necessary gluten free diet. 

-Maybe in the future if they develop a test where they put your DNA/intestine into a petrie dish to see if it reacts, I'll entertain that idea.  A full blown gluten challenge would alienate me from my friends and family because of my terrible mood.

 

I've always been a curious person who wants to know why, and sometimes there isn't always an answer and that drives me nuts.  Before last year, I didn't even know what PubMed was, and now I realize what an awesome resource it is for celiac research and otherwise! 

 

At this point I've exhausted all my options, and so it's time to find my inner peace and let it go.  I'm simply going to say, "No gluten for this girl!" :)

I am also a "I want to know why! " kind of person and research satisfies my curiosity most times. ^_^

 

They are always working on ways to better diagnose this thing, so perhaps in the future, there will be less hassle, less confusion, less people who fall through the cracks and less people left wondering WHY.

 

(and my very cool GI doctor told me he biopsied a man who was seronegative, neither a DQ2 or DQ8 and his villi were totally flat. He said symptoms were his guide in determining the medical necessity. We need more like him.) .

 

And for what it is worth, I think you have a most positive outlook and attitude and I think your username fits you to a T.

Thanks, Irish  :) My username at this time last year didn't fit me at all, but I've grown into it  :P  I remember thinking that I needed to focus in general more on the positives in life, so that's why I chose it.  This last year has really taught me a lot about myself and that rough times will always ebb and flow, but life is a lot easier when you focus on the positives!  It also greatly helps when you realize your problems all along were caused by a tiny, little protein called gluten  :lol:

PoPT is a good name.  :) I think your drive to understand "why" will help you get better faster than most others. Actively researching and not just trusting in others can only help.... Okay, it can frustrate the researcher, but overall it's a good thing.  LOL

My hubs and I have discussed this often. Really...think about how bizarre it is that one food protein makes your own body attack itself

and can kill you if left unchecked. When I think about how really, really bad it got for me and how I actually looked and felt 20 years older

than I was...how I was wasting away and my brain deteriorated...(shudder!)

 

Seems more  like a plot for a cheesy sci-fi novel rather than a "real thing".

      Welcome to the forum, @Judy M! Yes, he definitely needs to continue eating gluten until the day of the endoscopy. Not sure why the GI doc advised otherwise but it was a bum steer.  Celiac disease has a genetic component but also an "epigenetic" component. Let me explain. There are two main genes that have been identified as providing the "potential" to develop "active" celiac disease. We know them as HLA-DQ 2.5 (aka, HLA-DQ 2) and HLA-DQ8. Without one or both of these genes it is highly unlikely that a person will develop celiac disease at some point in their life. About 40% of the general population carry one or both of these two genes but only about 1% of the population develops active celiac disease. Thus, possessing the genetic potential for celiac disease is far less than deterministic. Most who have the potential never develop the disease. In order for the potential to develop celiac disease to turn into active celiac disease, some triggering stress event or events must "turn on" the latent genes. This triggering stress event can be a viral infection, some other medical event, or even prolonged psychological/emotional trauma. This part of the equation is difficult to quantify but this is the epigenetic dimension of the disease. Epigenetics has to do with the influence that environmental factors and things not coded into the DNA itself have to do in "turning on" susceptible genes. And this is why celiac disease can develop at any stage of life. Celiac disease is an autoimmune condition (not a food allergy) that causes inflammation in the lining of the small bowel. The ingestion of gluten causes the body to attack the cells of this lining which, over time, damages and destroys them, impairing the body's ability to absorb nutrients since this is the part of the intestinal track responsible for nutrient absorption and also causing numerous other food sensitivities such as dairy/lactose intolerance. There is another gluten-related disorder known as NCGS (Non Celiac Gluten Sensitivity or just, "gluten sensitivity") that is not autoimmune in nature and which does not damage the small bowel lining. However, NCGS shares many of the same symptoms with celiac disease such as gas, bloating, and diarrhea. It is also much more common than celiac disease. There is no test for NCGS so, because they share common symptoms, celiac disease must first be ruled out through formal testing for celiac disease. This is where your husband is right now. It should also be said that some experts believe NCGS can transition into celiac disease. I hope this helps.

      My husband has had lactose intolerance for his entire life (he's 68 yo).  So, he's used to gastro issues. But for the past year he's been experiencing bouts of diarrhea that last for hours.  He finally went to his gastroenterologist ... several blood tests ruled out other maladies, but his celiac results are suspect.  He is scheduled for an endoscopy and colonoscopy in 2 weeks.  He was told to eat "gluten free" until the tests!!!  I, and he know nothing about this "diet" much less how to navigate his in daily life!! The more I read, the more my head is spinning.  So I guess I have 2 questions.  First, I read on this website that prior to testing, eat gluten so as not to compromise the testing!  Is that true? His primary care doctor told him to eat gluten free prior to testing!  I'm so confused.  Second, I read that celiac disease is genetic or caused by other ways such as surgery.  No family history but Gall bladder removal 7 years ago, maybe?  But how in God's name does something like this crop up and now is so awful he can't go a day without worrying.  He still works in Manhattan and considers himself lucky if he gets there without incident!  Advice from those who know would be appreciated!!!!!!!!!!!!

      You've done an excellent job of meticulously tracking the rash's unpredictable behavior, from its symmetrical spread and stubborn scabbing to the potential triggers you've identified, like the asthma medication and dietary changes. It's particularly telling that the rash seems to flare with wheat consumption, even though your initial blood test was negative—as you've noted, being off wheat before a test can sometimes lead to a false negative, and your description of the other symptoms—joint pain, brain fog, stomach issues—is very compelling. The symmetry of the rash is a crucial detail that often points toward an internal cause, such as an autoimmune response or a systemic reaction, rather than just an external irritant like a plant or mites. I hope your doctor tomorrow takes the time to listen carefully to all of this evidence you've gathered and works with you to find some real answers and effective relief. Don't be discouraged if the rash fluctuates; your detailed history is the most valuable tool you have for getting an accurate diagnosis.

      In this case the beer is excellent, but for those who are super sensitive it is likely better to go the full gluten-free beer route. Lakefront Brewery (another sponsor!) has good gluten-free beer made without any gluten ingredients.

      Welcome to the forum, @catsrlife! Celiac disease can be diagnosed without committing to a full-blown "gluten challenge" if you get a skin biopsy done during an active outbreak of dermatitis herpetiformis, assuming that is what is causing the rash. There is no other known cause for dermatitis herpetiformis so it is definitive for celiac disease. You would need to find a dermatologist who is familiar with doing the biopsy correctly, however. The samples need to be taken next to the pustules, not on them . . . a mistake many dermatologists make when biopsying for dermatitis herpetiformis.
