Test Results, advice appreciated

Hi, 

I'm hoping I can get a bit of guidance here until I get an appointment with a second doctor... I just had a second celiac panel and am confused about my results, as well as my doctor's interpretation. Any help or advice is appreciated, as I am totally new to learning about celiac disease. 

First testing (Oct 2016) 

Gliadin IGA 2.4  (normal range <14.9)

Gliadin IGG 19.2 (normal <14.9)......HIGH

ttG IGA  .5 (normal <14.9)

ttG IGG .8 (normal <14.9)

 

Second testing (May 2017)

Gliadin IGA 1.8 (normal <14.9)

Gliadin IGG 23.7 (normal <14.9).....HIGH (even higher than first test)

ttG IGA .5 (normal <14.9)

ttG IGG .8 (normal <14.9)

 

 

I also tested positive for ANA (autoimmunity), negative rheumatoid arthritis, have an enlarged thyroid (but no hashimotos).  I also experience diarrhea, gas, bloating, acid reflux/heartburn, extreme fatigue all the time, sensitivity to dairy. inflammation markers normal, normal HIDA scan, normal CT scan of abdomen. 

 

Doctor says "unlikely that you have celiac or gluten issues, i believe this positive igg is some sort of cross reaction"  but is unable to explain any further.....trying to research leads me to mixed answers. 

Any advice? 

 

Thank you so much .

A high on any one celiac test should result in a gastroenterologist doing an endoscopy to see if there is a positive diagnosis of celiac. There are members here that were only high on one test.

Just so you know, the test for gliadin IgG and IgA are probably deamidated gliadin.  This is important because those are considered very accurate celiac tests.  By your IgG levels, it would indicate celiac disease, but would need to be confirmed by biopsy.  See below...

This is from Mayo Clinic:

Positive test results for deamidated gliadin antibodies, IgA or IgG, are consistent with the diagnosis of celiac disease.

 

Negative results indicate a decreased likelihood of celiac disease.

 

Decreased levels of deamidated gliadin antibodies, IgA or IgG, following treatment with a gluten-free diet are consistent with adherence to the diet. Persistence of high levels of antibodies following dietary treatment suggest poor adherence to the diet or the presence of refractory disease. 

Cautions help-16.gif

Measurements of deamidated gliadin antibodies should not be relied upon exclusively to establish or rule out the diagnosis of celiac disease.

Deamidated Gliadin (assuming this was what your test was...does it happen to say Gliadin Lite II anywhere?) can show up positive for diseases other than celiac. It is a newer test, roughly 10 years old (used under that amount of time in the states) and the research is ongoing. It replaces the OLDER gliadin tests which MOST labs no longer use, but SOME still do. Trouble is, it has such a similar name to the older tests, most docs do not even know that it is a newer version and the old tests got such a bad rap, they disregard them all together.  All of the previous research on Deamidated Gliadin is that it is highly specific to celiac disease. Newer research is showing that this is not necessarily the case.

 

That being said, given the mixed research on the test and the fact that members here have had celiac disease damage on biopsy with only DGP being positive, I think it is irresponsible to not move forward with a biopsy and genetic testing. DGP shows up positive in young children before TTG does and it is possible it does the same in adults. More research needs to be done on that. In fact, one of the recent studies on false positive DGP actually points out one of the limitations of the study was the inability to track the participants for development of celiac disease.

 

STAY ON GLUTEN. Going off of it and on it again may effect your biopsy results as there is no "set" amount of time for a gluten challenge to cause the kind of damage in significant amounts to be picked up on biopsy.

 

You should also have an EMA test done. Rare that it would be positive with a negative TTG, but still possible as  some on these boards could tell you.

 

"cross reaction" to what? DGP can be found positive in autoimmune diseases, but I am unaware of what "cross reaction" means. Sounds like bulls$#& to me.

 

You might need to shop for another doc while you continue eating delicious donuts (chocolate covered white cream) awaiting your further testing.

 

Good luck.

      I do not know this, but since they are labelled gluten-free, and are not really a product that could easily be contaminated when making them (there would be not flour in the air of such a facility, for example), I don't really see contamination as something to be concerned about for this type of product.

      @Jane02, I hear you about the kale and collard greens.  I don't do dairy and must eat green leafies, too, to get sufficient calcium.  I must be very careful because some calcium supplements are made from ground up crustacean shells.  When I was deficient in Vitamin D, I took high doses of Vitamin D to correct the deficiency quickly.  This is safe and nontoxic.  Vitamin D level should be above 70 nmol/L.  Lifeguards and indigenous Pacific Islanders typically have levels between 80-100 nmol/L.   Levels lower than this are based on amount needed to prevent disease like rickets and osteomalacia. We need more thiamine when we're physically ill, emotionally and mentally stressed, and if we exercise like an athlete or laborer.  We need more thiamine if we eat a diet high in simple carbohydrates.  For every 500 kcal of carbohydrates, we need 500-1000 mg more of thiamine to process the carbs into energy.  If there's insufficient thiamine the carbs get stored as fat.  Again, recommended levels set for thiamine are based on minimum amounts needed to prevent disease.  This is often not adequate for optimum health, nor sufficient for people with absorption problems such as Celiac disease.  Gluten free processed foods are not enriched with vitamins like their gluten containing counterparts.  Adding a B Complex and additional thiamine improves health for Celiacs.  Thiamine is safe and nontoxic even in high doses.  Thiamine helps the mitochondria in cells to function.  Thiamine interacts with each of the other B vitamins.  They are all water soluble and easily excreted if not needed. Interesting Reading: Clinical trial: B vitamins improve health in patients with coeliac disease living on a gluten-free diet https://pubmed.ncbi.nlm.nih.gov/19154566/ Safety and effectiveness of vitamin D mega-dose: A systematic review https://pubmed.ncbi.nlm.nih.gov/34857184/ High dose dietary vitamin D allocates surplus calories to muscle and growth instead of fat via modulation of myostatin and leptin signaling https://pubmed.ncbi.nlm.nih.gov/38766160/ Safety of High-Dose Vitamin D Supplementation: Secondary Analysis of a Randomized Controlled Trial https://pubmed.ncbi.nlm.nih.gov/31746327/ Vitamins and Celiac Disease: Beyond Vitamin D https://pmc.ncbi.nlm.nih.gov/articles/PMC11857425/ Investigating the therapeutic potential of tryptophan and vitamin A in modulating immune responses in celiac disease: an experimental study https://pubmed.ncbi.nlm.nih.gov/40178602/ Investigating the Impact of Vitamin A and Amino Acids on Immune Responses in Celiac Disease Patients https://pmc.ncbi.nlm.nih.gov/articles/PMC10814138/

      Thank you so much @knitty kitty for this insightful information! I would have never considered fractionated coconut oil to be a potential source of GI upset. I will consider all the info you shared. Very interesting about the Thiamine deficiency.  I've tracked daily averages of my intake in a nutrition software. The only nutrient I can't consistently meet from my diet is vitamin D. Calcium is a hit and miss as I rely on vegetables, dark leafy greens as a major source, for my calcium intake. I'm able to meet it when I either eat or juice a bundle of kale or collard greens daily haha. My thiamine intake is roughly 120% of my needs, although I do recognize that I may not be absorbing all of these nutrients consistently with intermittent unintentional exposures to gluten.  My vitamin A intake is roughly 900% (~6400 mcg/d) of my needs as I eat a lot of sweet potato, although since it's plant-derived vitamin A (beta-carotene) apparently it's not likely to cause toxicity.  Thanks again!

      Hello, @Jane02,  I take Naturewise D 3.  It contains olive oil.   Some Vitamin D supplements, like D Drops, are made with fractionated coconut oil which can cause digestive upsets.  Fractionated coconut oil is not the same as coconut oil used for cooking.  Fractionated coconut oil has been treated for longer shelf life, so it won't go bad in the jar, and thus may be irritating to the digestive system. I avoid supplements made with soy because many people with Celiac Disease also react to soy.  Mixed tocopherols, an ingredient in Thornes Vitamin D, may be sourced from soy oil.  Kirkland's has soy on its ingredient list. I avoid things that might contain or be exposed to crustaceans, like Metagenics says on its label.  I have a crustacean/shellfish/fish allergy.  I like Life Extension Bioactive Complete B Complex.  I take additional Thiamine B 1 in the form Benfotiamine which helps the intestines heal, Life Extension MegaBenfotiamine. Thiamine is needed to activate Vitamin D.   Low thiamine can make one feel like they are getting glutened after a meal containing lots of simple carbohydrates like white rice, or processed gluten free foods like cookies and pasta.   It's rare to have a single vitamin deficiency.  The water soluble B Complex vitamins should be supplemented together with additional Thiamine in the form Benfotiamine and Thiamine TTFD (tetrahydrofurfuryl disulfide) to correct subclinical deficiencies that don't show up on blood tests.  These are subclinical deficiencies within organs and tissues.  Blood is a transportation system.  The body will deplete tissues and organs in order to keep a supply of thiamine in the bloodstream going to the brain and heart.   If you're low in Vitamin D, you may well be low in other fat soluble vitamins like Vitamin A and Vitamin K. Have you seen a dietician?
