Help understanding follow-up test results

My daughter (now 12) was diagnosed in Jan. 2020 and her tTG IgA was in the high 100s if I recall correctly. After a gluten-free diet for over a year, the number was down to 15. At her next follow up almost 1 1/2 years later, the tTG IgA was higher again, at 38. She has never been symptom free (main complaints are daily nausea, random sharp abdominal pain a few times a day). We are quite strict with diet, do not eat out (other than a couple of times a year at dedicated gluten-free restaurants). She does eat more processed foods (gluten-free pasta, bread, chicken nuggets etc) than is ideal. Our home is gluten-free, she takes lunch from home to school, etc.

 

My question is, is this higher number and her symptoms clearly a result of continued contamination? I've seen members discuss those numbers being high due to other issues, but her GI didn't mention that possibility. I've combed through everything she eats and possible contamination sources and I'm at my wits end trying to figure this out. Any help would be greatly appreciated!

Here are her test numbers:

Endomysial IgA: negative (previously positive)

IgA: 118 

Glidadin (Deamidated Peptide) IGA Ab: 10.2 (previously 42)

Gliadin (Deamidated Peptide) IgG Ab: 3.2 (previously 55)

Tissue Transglutaminase (tTG) IgA: 38.9 (previously 15)

Tissue Transglutaminase (tTg) IgG: 4.0 (previously 6)

There are some other medical conditions and some foods and meds that can cause elevated tTG-IGA. Crohn's disease is one. NSAIDS can cause elevated tTG-IGA. Dairy and oats (even gluten-free oats) for some celiacs causes a celiac reaction for some people. You might google, "What can cause elevated tTG-IGA besides gluten" and "What can damage small bowel villi besides gluten."

Are her vitamins and supplements gluten free? Wheat starch can be used in pills as a filler. Are the other members of the household practicing gluten free eating at home? Some people on our forum experience glutening from shampoos, body creams and lotions (any epidermal contact with wheat), and oral hygiene products.

She doesn't consume any oats, and rarely takes NSAIDS. She does have a fair amount of dairy, though. 

 

Yes, her vitamins and supplements all claim to be gluten free. Everyone is gluten free at home. I've done my best to check all of the personal care/hygiene products to ensure they're gluten free as well.  

 

I'll read up on your suggested searches. Thank you for your input!

Mucosal reactivity to cow's milk protein in coeliac disease

I would give dairy a good look as the possible problem: https://pubmed.ncbi.nlm.nih.gov/2262836/ This is a very common additional food intolerance among the celiac population.

Thanks for the responses! We'll be cutting out dairy to see if that helps.

      Christmas Cake

      By cristiana · Posted

      Hello all I am taking some time out from work today to make my annual Christmas cake along the lines of a tried and tested English recipe which means a fruit cake, with marzipan  and icing.   As usual, I've left it too late - we're meant to bake these things some time  in advance to improve the flavour.    I never remember.  But it never seems to matter! I thought I'd share it in case any UK coeliacs still haven't made theirs and don't have a recipe, or any of my friends across the Pond want to try making one.  Do you make iced fruit cakes like this in the US for Christmas? - I have no idea! I adapt it slightly as instead of fondant icing I make Royal Icing which sets hard and you can create exciting snow scenes with it if you can find any tiny model houses, churches and trees to put on it!  (my Mum used to do this).   https://www.coeliac.org.uk/information-and-support/your-gluten-free-hub/home-of-gluten-free-recipes/1511804/ With thanks to the charity Coeliac Uk for this recipe.

      My 5 months of Struggle

      Welcome to the forum, @Art Maltman! Ask your physician to order serum antibody tests specifically designed to detect celiac disease. That's the place to start but you shouldn't be on a gluten free diet some weeks before the blood draw. You certainly have some symptoms that are characteristic of celiac disease and you have a first degree relative that has celiac disease. So, I think this would be an appropriate request to bring to your physician. Here is an article outlining the various serum antibody tests that can be ordered when checking for celiac disease:   The physician may not be open to ordering a full panel but push for at least these two: total IGA and tTG-IGA. By the way, absence of gut pain is very common in the celiac population. We call them "silent" celiacs as they have no or very minor symptoms. There are over 200 symptoms and spinoff health issues that have become associated with celiac disease and the range of symptoms and effects produced by the disease in different individuals various tremendously.

      My 5 months of Struggle

      By Art Maltman · Posted

      About 5 Months ago I got a little bit sick and since then I have been having trouble focusing, rembering, thinking thought through, having pressure on my head and even just talking to friends normaly has become a challange. I also have been having yellowish poops. My father was has celiac but I am not sure if thats what is causeing my problems becasue I dont have any abdomnial pain like him. i have also tried going gluten free for a week with no results, but maybe i just need to try for longer. I have gone to doctors but they haven't had really any ideas as to whats wrong with me they just say it could be anything and try this drug maybe it will work. I really am tired of feeling terrible all the time and if any one knows if these symptoms are common to celiac or has any other ideas whats wrong with me please let me know.
