Hi there,

My 7 year old son just got blood work back from his pediatrician and although I'm certain he must have Celiacs she wasn't so sure. He won't see a pediatric GI for another two weeks but I was curious if these results were common outside of a celiac disease diagnosis? Thanks! 

 

Transglutaminase IgA 
Your Value <1 U/mL
Standard Range <15.0 U/mL
NEGATIVE

Gliadin Deamidated IgA
Your Value 34 U/mL
Standard Value <15.0 U/mL
Flag: High
POSITIVE

Welcome to the forum, Lauren0204!

The tTG-IGA is considered to be the centerpiece of celiac antibody testing. That one is negative. But with children, whose immune systems are not fully developed, it will be negative even when they have celiac disease. That is the value of running additional antibody tests as was done for your son. His positive Gliadin Deamidated IgA suggests he does have celiac disease. We often see this same pattern here on the forum when pediatric test results are posted.

There are other antibody tests that can be run in addition to the two that were run. Here is a primer: https://celiac.org/about-celiac-disease/screening-and-diagnosis/screening/

It is also common for the tTG-IGA to be negative when the total serum IGA is low. I wish that value had been tested and reported for your son. The pediatric GI doc may want to order a more complete celiac antibody panel but he/she may also want to do an endoscopy/biopsy to check or damage to the villi that line the small bowel. In the meantime, it is important to make sure your son eats regular amounts of gluten. Otherwise, the test results may be invalid.

Unfortunately, many family physicians are not well-versed on gluten related disorders such as celiac disease and NCGS (Non Celiac Gluten Sensitivity) and many older GI docs are not much better. There has been a tremendous amount of research and discovery done concerning gluten related disorders since they were in med school. Because of that, as a parent you must do your own research and be armed with information when you go to appointments. Be prepared to be appropriately assertive in order to get thorough testing done.

Thanks so much for the response, so very informative much more so than the doctor was. They tried to tell me to just put my child on miralax for constipation and that would solve his severe stomach pain, even though he's never been constipated. I had to push for the blood work, so I assume I'll have to continue to advocate for him until I can get a straight answer.

Let me correct something I said here: "The tTG-IGA is considered to be the centerpiece of celiac antibody testing. That one is negative. But with children, whose immune systems are not fully developed, it will may be negative even when they have celiac disease." 

If your pediatric GI doc wants to do an endoscopy with biopsy, ask about how many samples he takes and from where. We frequently have posters on the forum whose doctors only took a couple of samples and declared there was no damage to the villi. But a second, more thorough biopsy was performed by another doc who found damage. The damage can be patchy and easily missed in the early stages of the disease. We would recommend like four samples each from the duodenum and the duodenum bulb. You would not want to have to unnecessarily repeat the procedure.

By the way, what are your son's symptoms? What led to this investigation of celiac disease?

He was having severe stomach pains on and off for several weeks and we couldn't find a reason. But now with the possibility of it being caused by celiac disease the more I research the more I understand he could have been showing symptoms for much longer (headaches, allergies, eczema, enamel spots on his new adult teeth etc. ) than just a few weeks.

I such add too that he lost 5lbs in less than 2months,which was very alarming as well bc he's already a tall skinny child so it was very noticeable.

Someday, you son will be very grateful that his mom (parents?) got on top of this at an early stage of his life. Most of us suffered with it for many years before ever getting diagnosed and by the time we were diagnosed there was damage to body systems that could not be reversed, mainly due to the nutritional deficiencies from malabsorption that celiac disease produces. Ruined teeth, stunted growth, osteopenia/osteoporosis, neurological damage, etc. 

Keep us posted.

Thanks so much for the kind words. Yes I'm determined to get a diagnosis so no more damage is done.

Lauren, in the celiac population there is a tendency to develop intolerance to some other foods that do not contain gluten. Chief among them are dairy products but also oats and egg intolerance are not uncommon. It may be because of the damage to the small bowel villi or because the proteins found in these other foods mimic the effect of gluten in some people. With dairy there is lactose (the sugar in milk) but also a possibility that the protein casein is the culprit. Research has shown that casein can blunt SB villi like gluten does in some people.

Keep in mind that celiac disease is at heart an immune disorder where the body mistakenly reacts to gluten as an invader. Over time, especially when celiac disease goes undiagnosed and unheeded, the immune system tends to become more dysfunctional so as to include other food proteins in it's list of false invaders. 

Personally, I would not worry about anything but gluten to begin with if it turns out your son does indeed have celiac disease. Chances are he won't have issues with other foods but it's just something to keep in mind if, over a period of weeks and months, he doesn't show much improvement after withdrawing gluten.

because there's cases of children reacting to dairy the same as with gluten... 

and ya maybe lactose intolerance too until healed.

      Your high lactulose test, indicating out of control Small Itenstinal Bacterial O,vergrowth is one symptom.  You likely have low vitamin D, another symptom.  Unless you get lots of sun.   Celiac Disease is a disease of malabsorption, often leading to subclinical vitamin deficiencies.  A lot of people have these symptoms just before an acute phase of Celiac Disease.  Each of the symptoms can have multiple causes that are not celiac disease,  but when you start having multiple symptoms,  and each symptom is treated as a separate disease,  you have to think, maybe these are all one cause. celiac disease. There is a misconception that Celiac Disease is  a gastrointestinal disease and symptoms are only gastro related.  Wrong.  It is an autoimmune disease and has many symptoms that usually are disregarded.  I made that mistake until 63 y.o.  It can cause a dermatitis herpetiformis rash,  white spots on the brain.  It caused my alcoholism, arthritis, congested sineses, protein spots on my contacts lenses, swollen prostate, symptoms that are "part of aging". You may be tolerating gluten, the damage will happen. Of curiosity though, your age, sex, are you outside a lot without sunscreen?

      It would be interesting to see if you were tested again for blood antibodies after abandoning the gluten free diet for several weeks to a few months what the results would be. Don't misunderstand me. I'm not necessarily suggesting you do this but it is an option to think about. I guess I'm saying there is a question in my mind as to whether you actually ever had celiac disease. As I said above, the blood antibody testing can yield false positives. And it is also true that celiac-like symptoms can be produced by other medical conditions.

      Thank you for the reply In the early 2000's I did not have the endoscopy nor the biopsy I do not have those initial records I have only consulted a GI drs in the USA

      Welcome to the forum, @numike! We sometimes get reports like yours from community members who believe their celiac disease has "gone away." We think there can sometimes be cases of remission but not long term healing and that continued consumption of gluten will eventually result in a relapse. This is the state of our knowledge at this point but there is still a lot we don't know and celiac disease continues to surprise us with new findings on a frequent basis. So, we would not advise you to abandon a strict gluten-free diet. Perhaps you can draw consolation from the fact that at the present time you seem to be able to consume gluten without consequences when in situations where you do not have the option to eat gluten-free. But I would advise you to not generalize your recent experience such that you throw caution to the wind. But I want to go back to what you said about being diagnosed by blood test in the early 2000's. Did you not also have that confirmed with an endoscopy and biopsy of the small bowel lining? Normally, a celiac disease diagnosis is not concluded based on a blood test alone because there can be false positives. What kind of doctor did this testing? Was it done in the U.S. or overseas? In the last few years, it has become common in the U.K. to grant a celiac diagnosis from blood testing alone if the antibody test scores are 10x normal or greater. But that practice has not caught on in the U.S. yet and was not in place internationally in the early 2000's. Do you have a record of the tests that were done, the scores and also the reference ranges for negative vs. positive for the tests?
