      Weakly positive DGP IgA

      By Cat M · Posted

      Ah ok, I just saw didn’t even post the DGP IgA at all. 😫 I started with itching and hives Jan 2024, been taking a ton of meds and on Xolair and even that is not providing total relief. The other primary symptoms: intermittent but worsening abdominal pain, diarrhea and bloating. This summer I am just exhausted. I uploaded my 23andMe data to genetic lifehacks and discovered quite a few variations, including DQ2, MTHFR, VDR and I have always had very low ferritin, vitamin D and B12. I still think that mast cell disease makes the most sense, but latest labs show I am barely in range for thiamine, zinc and vitamin A, so the GI stuff feels more important to figure out than the hives right now. I did SIBO testing this morning. TTG IGA <2   0-3 is negative TTG IGG  3   0-5 is neg DGP IGA 21    20-30 is weak positive DGP IGG 4    0-19 is negative Although total IGA is not resulted, there is a footnote stating it was low and the reason they ran IGG.

      Positive TTG antibody and negative EMA antibody

      By Scott Adams · Posted

      This is an interesting case. A positive tissue transglutaminase (tTG) antibody with a negative endomysial antibody (EMA) and normal duodenal histology can present a diagnostic challenge, especially in an asymptomatic patient. While the absence of villous atrophy and negative EMA suggest that the likelihood of active celiac disease is low at this time, such serological discordance may still warrant monitoring. Some individuals may be in the early stages of celiac disease, often referred to as potential celiac disease, particularly if they carry the HLA-DQ2 or DQ8 haplotypes. HLA typing can be quite helpful in this situation; a negative result would virtually rule out celiac disease, whereas a positive result may justify periodic follow-up to monitor for evolving disease. The risk of progression to overt celiac disease is not well defined but appears to be higher in children, those with a family history, or those with autoimmune conditions. In this case, routine follow-up including repeat serology and consideration of symptoms or new risk factors over time would be a reasonable and cautious approach. For people with celiac disease hidden gluten in their diets is the main cause of elevated Tissue Transglutaminase IgA Antibodies (tTG-IgA), but there are other conditions, including cow's milk/casein intolerance, that can also cause this, and here is an article about the other possible causes:

      Have you tried to start a gluten-free diet since your diagnosis in 2019?

      Positive TTG antibody and negative EMA antibody

      By trents · Posted

      Welcome to celiac.com, @Wamedh Taj-Aldeen! Just curious, what is your relationship to the patient? Are you the attending physician? A medical student? A consulted physician? Was a total IGA test ordered? Some physicians are under the dated and mistaken impression that such is only necessary in young children. If total IGA is low, other IGA antibody numbers will be artificially depressed. By the way, it is not unusual to have a positive TTG-IGA and a negative EMA. Are the TTG-IGA numbers borderline high or unequivocally high? There are other diseases and medical conditions that can cause elevated TTG-IGA numbers besides celiac disease but when this is the case, the numbers are usually not dramatically elevated. It can also be the case that villous damage was patchy and affected areas were missed during the biopsy. Or, onset of celiac disease was very recent and villous atrophy has not yet progressed to the point of detectability.  We also have occasional anecdotal reports in this online community of positive antibody testing with negative histology, as you report. But we also know that gluten intolerance can manifest itself apart from enteropathy. It can damage other organ systems. Many celiacs are of the "silent" type, meaning there is an absence or a relative absence of symptoms until the disease has become advanced and there is significant damage to the villous lining or other organ systems. But to answer your questions: 1. I would definitely pursue a routine follow-up and recheck of the antibodies. And, I would order a complete celiac panel including total IGA and IGG stuff in say, six months. Sooner if symptoms manifest. 2. It is impossible to say what is the risk of the future development of over celiac disease. I refer you back to my #1 above concerning rechecking.  3. I would definitely pursue HLA DQ2/DQ8 typing as it can be used as a rule out for celiac disease, though not quite with 100% dependability. I hope my thoughts prove helpful to you.

      Welcome to the forum, @dominiqueccms! Unfortunately, your story is all too common. Some older physicians are dismissive when it comes to gluten intolerance disorders and have this attitude like, "It's the latest fad disease." My advice to you is to get another doctor who has more current knowledge in this area and will take this seriously. In the meantime, this might be helpful: In six months to a year you would do well to get your antibody numbers rechecked to see if you are succeeding in your efforts to eat gluten free. Do you have the numbers from the original testing?
