5 year old son's results...still confused!

Hello! My son has a history of GERD since birth, and was on alimentum formula, was dairy free, and things just didn't really resolve...we were just managing.

Fast forwarding to now...he just had testing done and his DGP IgA was 40.5. Does this usually mean celiacs? 

Back in February he was diagnosed with duodenitis, and the TtG IgA was negative. He was doing a bit better with medication initially, but then this summer got worse. Then at the end of the summer he had rectal bleeding, which has been an isolated incident. 

I know I need to wait on the doctor, but I'm just trying to grasp the possibilities at this point. Thanks for any insights or thoughts!!

Welcome to the forum, Mel43.

Can you provide the negative vs. positive range for the DGP-IGA? There is no industry standard and each lab uses their own ranges.

The tTG-IGA test can generate a false negative if total IGA is low. I would ask your physician to run this test. It is often omitted but especially for children it should be run along with tTG-IGA. With children, we often see elevated DGP-IGA even though the tTG-IGA is negative in cases where the child actually does have celiac disease.

It is important that your son not cut back on gluten consumption until all testing for celiac disease is complete, including an endoscopy with biopsy should your physician decide to order that or to refer your son to a GI doc for such.

Thank you! For the DPG-IGA it lists 0-13.9 as being normal. Max's was 40.5.  His DPG-IGG was 6, with normal being 0-14.9.

His TTG-IGA was <0.5, with normal also being 0-14.9.

When my son was diagnosed with Celiac Disease as soon as he was weaned he was put on Nutramigen.  That was back in 1976 and it is still the best.  Improvement was immediate and he grew up fine and strong. It is the only hypoallergenic baby formula with 100% of all the essential nutrients.  They make a version for toddlers.

Let me reiterate that Max should not reduce his gluten intake (wheat, barley and rye) until all testing for celiac disease is done. Withdrawal of gluten before testing will compromise the test results as it will allow inflammation of the small bowel lining to subside (if Max in fact has celiac disease) and antibodies will therefore cease to be produced.

Also, his DGP-IGA is strongly positive. This is often a more reliable indicator of celiac disease in young children than is the tTG-IGA.

This article might be helpful. It breaks down each type of test, and what a positive results means in terms of the probability that you might have celiac disease. The next step might be an endoscopy to confirm a celiac disease diagnosis, and if that ends up being negative you may still want to try out a gluten-free diet to see if his symptoms improve.  Approximately 10x more people have non-celiac gluten sensitivity than have celiac disease, but there isn’t yet a test for NCGS. If your symptoms go away on a gluten-free diet it would likely signal NCGS.

Thank you all so much for the information! We did the genetic testing, and I'm waiting for the doctor to respond. I'm not sure what this means...his results for DQ2/DQX says value III, high. I'm so lost!

DQ2 is one of the genes that have been proven to be connected to the potential to develop celiac disease. People with the DQ2 who do develop celiac disease tend to be in the most sensitive, severe reaction to gluten group.

      Struggling to get into a good pattern

      By cristiana · Posted

      Since I've been a member of this forum,  I've seen some people write that they have not been able to tolerate corn, and others nightshades - tomatoes, potatoes, eggplant, and peppers (including bell peppers, chili peppers, and paprika).    However, intolerances can be short term, just while you are healing.    So bear this in mind if you start dropping certain foods from your diet - you may well be able to eat them again once you are healed.

      Welcome to the forum, @Izelle! Normally, the diagnosis of celiac disease involves two stages.  The first stage involves a simple blood test that looks for antibodies that are pretty specific to celiac disease. Celiac disease is an autoimmune disorder that attacks the lining of the small bowel which produces antibodies that can be detected in the blood with tests specifically designed for this purpose. There are a number of these tests that can be run. Some are more specific for celiac disease and thus more reliable than others. The two most common antibody tests ordered by physicians when diagnosing celiac disease are the "total IGA" and the "tTG-IGA" test. At least these two should always be ordered. Here is a an article outlining the subject matter of celiac antibody tests:  If the tTG-IGA levels are 10x normal then it is becoming common practice in some countries to grant a celiac diagnosis on the bloodwork alone. The second stage involves an endoscopy with biopsy of the small bowel lining to look for the damage to the small bowel lining typically caused by celiac disease's inflammatory process over time. This is usually done in response to one or more positives from the blood antibody testing and constitutes confirmation of the antibody testing to eliminate the possibility of false positives.

      Diagnosed gluten allergy but not Celiac

      By Waterdance · Posted

      Thank you for saying that. That doctor diagnosed me with IBS with no follow-up so the relationship is already concluded. If I pursue diagnosis further I'll request someone else.

      By Rejoicephd · Posted

      Hey everyone. Thanks again for your suggestions. I wanted to give an update and ask for some follow-up suggestions from you all.  So I did go through all of my food items and stopped eating things that were “gluten free” and switched over to the “certified gluten free” ones (the ones with the g symbol). I also stayed away from restaurants except once and there I ordered something raw vegan and gluten free hoping for the best. I also stayed away from oats and soy and dairy. I've also been increasing my vitamin B complex. I've been doing this for about 12 days and while I know that's not that long, I'm still getting sick. Sometimes having diarrhea. Sometimes getting headaches and having necklaces. Sometimes waking up feeling horrible brain fog. I did go to my GI doc and they did a blood test and found my TtG-IgA was in the negative range (and a lower number than I'd had before). I also had normal levels of CRP. My stool showed no elevation of calprotectin and no pathogens. My GI doc said the symptoms could be related to a gluten exposure or to IBS. I'm keeping a food diary to see if I can narrow down whats going on. I know I have good days and bad days and Im trying to isolate what makes a good day versus a bad day. Generally so far it looks like if it eat something super cautious like raw vegetables that I chopped myself into a salad and almonds, im fine but if I eat something more complex including, say, chicken and rice (even if packaged and certified gluten free or made by me with gluten free ingredients), it may not go so well. I may end up with either a headache, neck tension, brain fog, and/or diarrhea that day or the morning after. Any other thoughts or suggestions? I am planning to start tracking my foods again but I wanted to do it in more detail this time (maybe down to the ingredient level) so are there any common ingredients that celiacs have issues with that you all know of that I should track? I've got dairy, oats, soy, eggs, corn, peas, lentils on my “watch list”. Other things I should add? I'm hoping if I track for another two weeks I can maybe pin down some sensitivities. Appreciate the help and tips. Thank you so much!!
