Do Adults with High Gliadin Antibody Concentrations have Subclinical Gluten Intolerance?

Please note that this study has no biopsy confirmation, so it can only be called gluten intolerance statistics. Its findings indicate that gluten intolerance may be relatively common in the general population.

SO - Gut 1992 Feb;33(2):194-7 AB - Gliadin antibodies of the IgG and IgA isotopes and IgG subclasses were measured in 200 adults who were randomly selected from the Icelandic National Register.

Those with the highest gliadin antibody concentrations were invited with negative controls to participate in a clinical evaluation. Neither the study subjects nor the physicians who recorded and evaluated the clinical findings were aware of the antibody levels. Significantly higher proportion of the gliadin antibody positive individuals reported unexplained attacks of diarrhea (p = 0.03), and IgA gliadin antibodies were associated with increased prevalence of chronic fatigue (p = 0.0037). The gliadin antibody positive group also showed significantly decreased transferrin saturation, mean corpuscular volume and mean corpuscular hemoglobin compared with the gliadin antibody negative controls. Serum folic acid concentrations were significantly lower in the IgA gliadin antibody positive individuals. On blind global assessment, 15 of the 48 participants were thought to have clinical and laboratory features that are compatible with gluten sensitive enteropathy, and 14 of these were in the gliadin antibody positive group (p = 0.013). Complaints that have not been associated with gluten intolerance had similar prevalence in both groups with the exception of persistent or recurrent headaches that were more common in the gliadin antibody positive group. These findings raise the possibility that a sub-clinical form of gluten intolerance may be relatively common.

The following chart summarizes the study:

No. Randomly Selected for Study No. Selected w/ High Gliadin No. w/ Gluten Sensitive Enteropathy No. w/ GSE & High Gliadin
200 ( = 100%) 48 ( = 24%) 15 ( = 7.5%) 14 ( = 7%)

This is a great explanation. There are several great research organizations out there researching this as well to gain even better understanding. You can actually participate in the research and get paid for your time if you are diagnosed with diseases like Celiac, and many others. The research helps to develop diagnostic tests and cures, and you are paid anywhere from $200 to $1000 every time you participate.

It sounds like your hives resolved. I had a six month bout with them. Antihistamines really helped. My doctors are not sure if Mast Cell or autoimmune is the root cause.

My kid has Raynauds. It freaks her classmates out. She wears shoes and wool socks all year round and we live in a warm state. It is autoimmune. She manages it by layering, turning up the heat, use lots of blanket throws. I have Hashimoto?s and celiac disease. So, having multiple autoi...

Well, you do need to replace some things because they are too porous or damaged to remove gluten. Things like old wooden spoons, scratched non-stick pans, toaster, colander, sponges, etc. Honestly, the list is long, so try getting a few celiac books at the library or Amazon. Consider reading t...

When I woke up from my Endoscopy and was told I definitely had celiac disease the first thing I asked my doctor was do I need to get all new kitchen stuff? He assured me that I did not, and as long as my pots and pans and everything else was washed after being used to cook gluten I would have no ...

They have all given you good advice. Like Ennis_Tx said this is not medical advice. Just some observations. Ennis_Tx mentioned already a good B-complex. But people who have Perncious Anemia low B-12 have "Pens and Needles' feeling in their extremities. Mine was much more ...
