Is this celiac?

Hi I have recently been diagnosed with Celiac after having months of stool consistency and frequency issues and an upset stomach. The following was my results. Would you agree with a Celiac diagnosis? 

I have both genes for Celiac disease. My endoscopy biopsy showed mild intraepithelial lymphocytosis with preservation of the villlous architecture. my celiac blood panel had my t-transglutaminase (tTG)IgG positive at a 6. My Immunoglobulin A QN Serum was positive at a 366. 

 

My GI says it's celiac and to start a gluten-free diet. I have been on it for 3 weeks and am still having stomach and bowel issues.

You have used some terminology that is unfamiliar to me.

"preservation of the villlous architecture" Does this mean there was no villous atrophy?

"Immunoglobulin A QN Serum". Not sure what this is but it sounds like it might be referring to total IGA.

"tTG-IgG" was positive at 6". What is the reference range?

Did the physician run a tTG-IGA? That is considered the single best test for celiac antibodies. Yet, you do not list that in our results.

You may only think you are eating gluten free. It's much more difficult than most people think. Studies show that most who claim to be eating gluten free are actually practicing lower gluten eating. This primer may help: 

And three weeks might not be enough to see much improvement.

Hi yes, it means there was no villous atrophy. 

 

The tTG reference range said 0-5 was Normal. 6 was a weak positive. 

 

My ttg-iga did not get flagged.

The Immunoglobulin A QN Serum from what I read online is it protects against infections of the mucous membranes lining the mouth, airways, and digestive tract. If they are high it could be a sign of an autoimmune disease, etc.

Were you IGA deficient (low total IgA)? Just wondering why the physician ordered the tTG-IgG? Normally, that is run when total IGA is low since total IGA will suppress the individual IGA values.

I tried to copy and paste my celiac panel results below.  I am not sure which is the total IGA. 

 

Deamidated Gliadin Abs, IgA01 7 units 0-19
 Negative 0 - 19
 Weak Positive 20 - 30
 Moderate to Strong Positive >30
Deamidated Gliadin Abs, IgG01 2 units 0-19
 Negative 0 - 19
 Weak Positive 20 - 30
 Moderate to Strong Positive >30
t-Transglutaminase (tTG) IgA01 <2 U/mL 0-3
 Negative 0 - 3
 Weak Positive 4 - 10
 Positive >10
 Tissue Transglutaminase (tTG) has been identified
 as the endomysial antigen. Studies have demonstr-
 ated that endomysial IgA antibodies have over 99%
 specificity for gluten sensitive enteropathy.
t-Transglutaminase (tTG)
IgG01 6 High U/mL 0-5
 Negative 0 - 5
 Weak Positive 6 - 9
 Positive >9
Endomysial Antibody IgA01 Negative Negative
Immunoglobulin A, Qn,
Serum01 366 High Immunoglobulin A, Qn,

Serum01 366

The tTG-IGG is less accurate (less specific for celiac disease) than the tTG-IGA is my understanding. The fact that you have no villous atrophy really is the key here as that is considered the gold standard for diagnosing celiac disease. Sometimes, however, we get people who are tested while in the early stages of celiac disease who have negative biopsies. If I were you I'd be investigating things like IBS and SIBO.

https://www.webmd.com/a-to-z-guides/immunoglobulin-test#:~:text=If your immunoglobulin level is,arthritis%2C lupus%2C or celiac disease

If your immunoglobulin level is high, it might be caused by:

Allergies

Chronic infections

An autoimmune disorder that makes your immune system overreact, such as rheumatoid arthritis, lupus, or celiac disease

Liver disease

Inflammatory bowel disease

Cancer, such as multiple myeloma, lymphoma, or leukemia

 

I would advise going back to your doctor and ask some questions about that one. I don't think you can yet rule out celiac disease but there are other possibilities that should be investigated.

I also want to add that around 10x more people have non-celiac gluten sensitivity, and there currently isn't a test for it. Since you have unexplained symptoms, and one positive blood test for celiac disease, you may still want to try a gluten-free diet for a few months to see if they go away. Just be sure that your doctor doesn't have any future tests planned for celiac disease before doing so, as this could lead to false-negative results.

      Thanks @Scott Adams I've just read the recipe - it looks a fair bit healthier than mine, with carrots in it, it might even fulfil a person's 5-a-Day fruit and veg quota! I see the writer is of UK descent.  For one minute there, I thought that perhaps the  fruit cake, marzipan and icing thing wasn't just a weird thing we do in the UK?  I am now wondering how widely this type of English cake is consumed in the US.   @Kate333  I wondered if you have ever eaten this?

      For people with celiac disease hidden gluten in their diets is the main cause of elevated Tissue Transglutaminase IgA Antibodies (tTG-IgA), but there are other conditions, including cow's milk/casein intolerance, that can also cause this, and here is an article about the other possible causes:

      Eye irritation can be so frustrating, especially when you're already adjusting to life with celiac disease. It’s great that you’ve seen an eye doctor and taken steps like using a heat mask and drops, which seem to have helped with the dryness. Sometimes, lingering irritation can be linked to inflammation as your body heals, or even to other factors like allergies or environmental irritants (like dust or mold that might increase in colder months). Do you use lubricant eye drops like "Refresh"? I use this often, because I also have dry eye issues at times. It might also be worth reviewing your diet and environment for hidden gluten or allergens, as cross-contamination could contribute to systemic inflammation and affect your eyes. Some celiacs report lingering or unusual symptoms during the first year of healing—it’s a process, but you’re on the right track. If it persists, consider a follow-up with your doctor or an allergist to rule out anything else. Hang in there—you’re doing everything right to support your recovery!
