Lab Results

My 15yo daughter was vomiting really bad one day, followed by increasing stomach pain and constant burping (no more vomiting). The GI dr said "IBS" (even though she did not have symptoms of constipation and diarrhea)and maybe lactose intolerance. She was never lactose intolerant before, but we stopped lactose anyway and the pain continued. We got the following lab results, but the GI still thinks this is IBS since TTG and EMA were negative. We started the gluten free diet on our own after getting labs to try to help her and she is now starting to feel better. Do you think these labs indicate celiac? I just want to help her feel better.

TTG Ab IgA=negative

DGP IgG=4 + (range <1.3)

DGP IgA=6 + (range <2.9)

EMA IgA=negative

Total IgA=135 (44-441)

DQ2.5 (HLA DQA1*05:DQB1*0201)=DQ2 heterozygous

It looks like these results-

DGP IgG=4 + (range <1.3)

DGP IgA=6 + (range <2.9)

are positive and since these are the newest and best blood tests for celiac IMHO you are doing the right thing by having her go gluten free. It would be a good idea to test everyone in the family now.

Thank you!!! I feel like the pushy mom having to fight to get the labs done, and now to find a new GI dr who will listen, but I am willing to do whatever it takes. I will definitely get the rest of us tested.

ya, in my honest opinion- with the positive DGP, DQ2, symptoms, and relief on diet-> i would presume she is a celiac, and that you're catching it before it's bad enough to score positive on all the tests.

the EMA test is a difficult one to do in the lab- it is subject to human error and could easily be a false negative.

I would trust the DGP. Doctors have been taught to trust the TtG and the EMA.

If she is already gluten free and feeling better, combined with those test results, a new GI isn't really going to be of much help unless you put her on gluten again for a couple months so they can biopsy. Even back on gluten and feeling ill she may still have a false negative with the biopsy. You don't need a GI to test the other family members your regular GP can order the blood tests. Just make sure they don't stop eating gluten before testing. If your concerned that she may need the 'official' diagnosis for when she goes off to college talk to your GP and tell them of the good results on the diet and bring a copy of the blood test results. Your GP has likely known about her issues if they have been brought up in any office visits and may give her the 'official' diagnosis if you need it for school or college.

      For people with celiac disease and corn intolerance from it: Is salt still okay for most people?

      By trents · Posted

      Gluten-like cross reactions to other foods are from the proteins that make them up. Dextrose is the sugar component found in corn.

      For people with celiac disease and corn intolerance from it: Is salt still okay for most people?

      By Ryangf · Posted

      I just found out a few days ago that some salt like table salt contains dextrose that’s derived from corn. I’ve been thinking about getting rid of using table salt and just using my own kosher or Himalayan salt, but tbh I’m reluctant to do it. I’ve cut out a lot of things and I don’t really want to cut out anything else that I’m not sure will effect me…in a super small amount that it might be added to salts to stabilize the iodine. I don’t want to be further alienated when I have to go to a restaurant with my friends. Also most of the items at my house that have salt in it canned food etc. are some of the few quick things I can eat- because I’m not the one paying for the food in my household and i can only ask for so much. I’m not in a place financially where I can get a lot of my specialized items- although my family tries their best to get items I Can actually stand. I get I can bring a my own salt with me at a restaurant and ask for no seasoning but it feels like a lot to me- cause I already check for cross contamination and ask if the food has like a high volume of corn in it like cornstarch etc. I’ve also heard most dextrose is not derived from the Zein (corn gluten) portion of it- so it might be safe- but idk if that’s true. I just wanna know if anyone actually responded to it negatively.

      I’m so confused…

      By Scott Adams · Posted

      For my first couple of years after discovering my celiac disease I also had to avoid cow's milk/casein and eggs, as well as other things, but could tolerate duck eggs and sheep and goat's milk products. I'm not sure if you've tried those, but it could be worth testing them out.

      Hello, @Kwinkle, How are you doing?   Have you tried adding a Magnesium supplement?   The B Complex vitamins need magnesium to work properly, especially thiamine vitamin B 1.   Magnesium deficiency symptoms and Thiamine deficiency symptoms both include gas and bloating.  Thiamine deficiency symptoms also include loss of appetite and fatigue.   My gas and bloating resolved rather quickly when I took Benfotiamine (a form of thiamine shown to promote intestinal healing) and Magnesium Glycinate in addition to my B 50 Complex (all twice a day plus the following...).   I found Magnesium L-Threonate or Magnesium Taurate are better when taken with a form of thiamine called TTFD (Tetrahydrofurfuryl dusulfide) because all of these cross the blood brain barrier easily, which corrects the loss of appetite, fatigue and anxiety.    Like @Celiacandme said, keeping a food/mood/poo'd journal is a big help in finding problematic foods, and for making sure your diet is not carbohydrate heavy.  If you're eating a lot if processed gluten free facsimile foods, be aware they do not have vitamins and minerals added to them like their gluten containing counterparts.  For every 1000 kcal of carbohydrates, we need an extra 500 mg of thiamine to turn them into energy and not store them as fat.   Let us know how you're doing!

      Testing

      By Scott Adams · Posted

      Yes, if you had symptoms when eating gluten ruling out celiac disease won't necessarily mean you'll be able to eat gluten again, although it might mean that you may be able to be less strict with your gluten-free diet.
