Bloodwork Question...

My 3 year old daughter was tested for celiac about 6 months ago...the antigliadin IgA's and IgG's were both elevated but the reticulin and endomysial antibodies were negative. Because the antigliadin antibodies were elevated, the ped GI wanted to retest her, which we just did last week. Course they performed different tests this time, so we're unable to compare, but they did the endomysial and the ttg tests which were negative. Her total IgA's (not antigliadin specific) were actually elevated, so she's not IgA deficient. Just wondering if I should interpret this bloodwork as an absolute negative. The allergist did suggest trying a gluten-free diet due to the possibility of a wheat intolerance instead of celiac. Just wondering what your thoughts are! Thanks in advance!

Kid's with Celiac by Danna Korn has a chart in it for test results.

+ EMA-Iga/tTG

+AGA-IgG

=Interpretation - Celiac Disease almost certain

That is directly from the book and I am not a doctor!

So you're saying if the endomysial antibody is positive, along with the anti-gliadin IgG...then celiac is almost certain? Well, my daughter's EMA was negative on two different occasions. Funny, the allergist said that many people can have elevated anti-gliadin IgG's, but the IgA's were the ones that were most correlated with celiac. I would definitely be inclined to believe this man - he's very knowledgable and very well respected. (He's also very open minded, which is definitely a plus!) Thanks for your reply!

Your allergist is correct -- elevated IgG for gliadin is not necessarily specific for celiac. EMA is both very specific for celiac and a very good predictor (so a negative means negative most of the time...). IgA can be negative because you are celiac and don't have any, or negative because you aren't celiac at all. If your daughter's came back elevated, you know she actually has IgAs running around. Anyhow, a negative EMA and a negative tTg is going to be negative for celiac in most people's cases....

Don't really want to cause more confusion, but I thought I should point out that a positive IgA antigliadin test shows a reaction to gliadin(gluten), negative IgA tTg and EMA mean that the damage to the intestine is not severe enough to be called celiac, but your allergist is correct that it could be an intolerance to wheat (or gluten) and just not full blown Celiac. No one can say for certain if your daughter will get Celiac Disease later, but you could avoid it all toghether by trying the diet. I assume she must have symptoms or you wouldn't be testing her? If you are finished with testing at this point then it wouldn't be a bad thing to try the diet like the allergist suggested. If her symptoms improve, then you can be pretty sure that gluten is bothering her. You could also have her gene tested. Enterolab does a very good gene test, that included the genes for gluten intolerance, as well as the main genes for Celiac. It costs about $150. You don't need a doctors order either, and you do the test at home. Some people like the idea of having the gene test be private, since they don't want to be discriminated against by future insurance companies who don't want to cover you because you have a genetic disorder...So with Enterolab you have the choice of sharing the results with your doctor or not.

God bless,

Thanks for all the info! Yes my daughter does have symptoms, but she was actually diagnosed with inflammatory bowel disease. I still am a bit skeptical about the diagnosis, so I find myself questioning other possibilities. Her ped GI said she could have celiac in addition to IBD so that's why she's been tested. Her symptoms include loose, foul stools with mucous and, on occasion, trace amounts of blood. We first thought it was a dairy allergy. When we took dairy out of her diet, the blood increased. We did the elimination diet twice - the first time for 3 weeks and the second for 2 weeks. Both times, the blood in her stool increased. I know celiac doesn't normally cause blood, but I'm just wondering why taking dairy out increased her symptoms. Seems she was eating more wheat at the time to make up for the lack of dairy, so it seems logical that she was having some sort of reaction to wheat. But I guess you could also explain it by saying that gluten is tough on the body...it can be even tougher on a damaged intestinal tract causing more blood to appear. Anyway, enough about that. Thanks again for all the info! (By the way, I thought about Enterolab, but I'm very skeptical about the accuracy of the tests.)

  Funny, the allergist said that many people can have elevated anti-gliadin IgG's, but the IgA's were the ones that were most correlated with celiac.

Unfortunately, it is very true... and it means that there are A LOT of people out there with a gluten intolerance that aren't being helped. Elevated IgA is more specific to damage in the intestines... but an elevated IgG is nothing to ignore. The IgG antibodies are the one's that roam freely throughout the body and they are the one's, I believe, are causing the 'other' disorders that have been linked to celiac disease: thyroid, arthritis, diabetes...

If you have a gluten intolerance, evidenced by elevated antibodies to gliadin (IgA or IgG), then the only way to prevent from developing any disorder is to abstain from gluten.

The cure is simple and you don't need a prescription or a doctor to do it! :)

      In the study linked above, the little girl switched to a gluten free diet and gained enough weight that that fat pad was replenished and surgery was not needed.   Here's the full article link...

      Hello, @Jordan Carlson, So glad you're feeling better.   Tecta is a proton pump inhibitor.  PPI's also interfere with the production of the intrinsic factor needed to absorb Vitamin B12.  Increasing the amount of B12 you supplement has helped overcome the lack of intrinsic factor needed to absorb B12. Proton pump inhibitors also reduce the production of digestive juices (stomach acids).  This results in foods not being digested thoroughly.  If foods are not digested sufficiently, the vitamins and other nutrients aren't released from the food, and the body cannot absorb them.  This sets up a vicious cycle. Acid reflux and Gerd are actually symptoms of producing too little stomach acid.  Insufficient stomach acid production is seen with Thiamine and Niacin deficiencies.  PPI's like Tecta also block the transporters that pull Thiamine into cells, preventing absorption of thiamine.  Other symptoms of Thiamine deficiency are difficulty swallowing, gagging, problems with food texture, dysphagia. Other symptoms of Thiamine deficiency are symptoms of ADHD and anxiety.  Vyvanse also blocks thiamine transporters contributing further to Thiamine deficiency.  Pristiq has been shown to work better if thiamine is supplemented at the same time because thiamine is needed to make serotonin.  Doctors don't recognize anxiety and depression and adult onset ADHD as early symptoms of Thiamine deficiency. Stomach acid is needed to digest Vitamin C (ascorbic acid) in fruits and vegetables.  Ascorbic acid left undigested can cause intestinal upsets, anxiety, and heart palpitations.   Yes, a child can be born with nutritional deficiencies if the parents were deficient.  Parents who are thiamine deficient have offspring with fewer thiamine transporters on cell surfaces, making thiamine deficiency easier to develop in the children.  A person can struggle along for years with subclinical vitamin deficiencies.  Been here, done this.  Please consider supplementing with Thiamine in the form TTFD (tetrahydrofurfuryl disulfide) which helps immensely with dysphagia and neurological symptoms like anxiety, depression, and ADHD symptoms.  Benfotiamine helps with improving intestinal health.  A B Complex and NeuroMag (a magnesium supplement), and Vitamin D are needed also.

      @pothosqueen, Welcome to the tribe! You'll want to get checked for nutritional deficiencies and start on supplementation of B vitamins, especially Thiamine Vitamin B 1.   There's some scientific evidence that the fat pad that buffers the aorta which disappears in SMA is caused by deficiency in Thiamine.   In Thiamine deficiency, the body burns its stored fat as a source of fuel.  That fat pad between the aorta and digestive system gets used as fuel, too. Ask for an Erythrocyte Transketolace Activity test to look for thiamine deficiency.  Correction of thiamine deficiency can help restore that fat pad.   Best wishes for your recovery!   Interesting Reading: Superior Mesenteric Artery Syndrome in a 6-Year-Old Girl with Final Diagnosis of Celiac Disease https://pubmed.ncbi.nlm.nih.gov/31089433/#:~:text=Affiliations,tissue and results in SMAS.

      Wow! You're pretty young to have a diagnosis of SMA syndrome. But youth also has its advantages when it comes to healing, without a doubt. You might be surprised to find out how your health improves and how much better you feel once you eliminate gluten from your diet. Celiac disease is an autoimmune disorder that, when gluten is consumed, triggers an attack on the villous lining of the small bowel. This is the section of the intestines where all our nutrition is absorbed. It is made up of billions of tiny finger-like projections that create a tremendous surface area for absorbing nutrients. For the person with celiac disease, unchecked gluten consumption generates inflammation that wears down these fingers and, over time, greatly reduces the nutrient absorbing efficiency of the small bowel lining. This can generate a whole host of other nutrient deficiency related medical problems. We also now know that the autoimmune reaction to gluten is not necessarily limited to the lining of the small bowel such that celiac disease can damage other body systems and organs such as the liver and the joints and cause neurological problems.  It can take around two years for the villous lining to completely heal but most people start feeling better well before then. It's also important to realize that celiac disease can cause intolerance to some other foods whose protein structures are similar to gluten. Chief among them are dairy and oats but also eggs, corn and soy. Just keep that in mind.
