Patients with Celiac Disease, Multiple Myeloma React Differently to Various Kinds of Gliadin

Celiac.com 07/01/2009 - Immunity to food allergens such as gliadin, or the proteins in cow's milk is central to prevention of certain diseases via an appropriate restriction diet. Detecting heightened levels immune reactions to antigen(s) in food is important because scientists have credible reports of certain health disturbances, such as celiac disease, and some pre-malignant conditions, such as monoclonal gammopathy of undetermined significance (MGUS), disappearing under a regimen of appropriate food restriction diets.

Only a small number of genetically predisposed individuals show a toxic  small bowel mucosa reaction to gliadin. Since levels of immunogenic gliadin may vary between different wheat species, a team of researchers first set out to assess immunogenic gliadin levels in ten bread wheat types and in three strains of commercially grown durum wheat.

The team was made up of Aleksandra Konic-Ristic, Dejan Dodig, Radmilo Krstic, Svetislav Jelic, Ivan Stankovic, Aleksandra Ninkovic, Jelena Radic, Irina Besu, Branka Bonaci-Nikolic, Njegica Jojic, Milica Djordjevic, Dragan Popovic, and Zorica Juranic.

They were spurred by previous studies that showed sera of some of multiple myeloma (MM) patients with elevated levels of anti-gliadin IgA, without enhanced levels of anti-gliadin IgG antibodies, as determined by commercial ELISA test.

They designed their own specifically to uncover any hidden anti-gliadin IgG immunoreactivity in patient blood samples. For this reason, researchers tested blood of both MM patients and celiac disease patient for immunoreaction with native gliadin isolated from regional wheat species used for bread and pasta making.

The team isolated gliadin from wheat flour by two step 60% ehanolic extraction. They determined gliadin levels by commercial R5 Mendez Elisa using PWG gliadin as the standard.

Results showed immunogenic gliadin content varies between 50.4 and 65.4 mg/g in bread wheat samples and between 20 and 25.6 mg/g in durum wheat samples.

Anti-gliadin IgA and IgG immunoreactivity of patients'sera in (IU/ml) was first measured by commercial diagnostic Binding Site ELISA test, and then additionally by non-commercial ELISA tests, using standardized ethanol wheat extracts -gliadin as the antigen.

In both patient groups, IgA immunoreactivity to gliadin from different samples was almost homogenous and in correlation with results from commercial test, except for one IgA(lambda) myeloma patient. However, results for IgG immunoreactivity were less homogeneous.

Results showed different immunogenic gliadin epitope levels in various species of wheat. They also point to a need for developing a new standard antigen, a representative mixture of gliadin isolated from local wheat species used for bread production in corresponding geographic region for ELISA diagnostic tests.

Have been dealing with splinter hemorrhages on three of my toe nails since February. I did go to my doctor who rightly so did a very complete blood work-up ruling out other diseases such as lupus and RA and referred me to several other doctors to make sure that it was not cancer, endocarditis, or something serious. I went to the doctors. I have done some research on vitamin deficiency and it seems that some link splinter hemorrhages to vitamin C deficiency. For the past 2 1/2 weeks I have been eating 3 clementines a day (in addition to the usual multivitamin that I take) and it seems to be helping the splinter hemorrhages. One has grown out and not returned. Visited my GI doctor today and talked about malabsorption of nutrients as a potential issue. We are doing more blood work and checking nutrient levels. I have to believe it has something to do with the celiac. Sorry I don't have a better answer, but like you am trying to figure this out. Please let me know if you find any answers, and yes, be sure to check with your doctor to rule out anything serious.

You only need one positive on the celiac panel. I tested positive only to the DGP IgA and had a Marsh Stage IIIB intestinal damage. Good luck!

Welcome to the forum. First, you need to get copies of your celiac test to confirm you actually had it done and what the results were. Second, to confirm a diagnosis, you must obtain biopsies via an endoscopy. Were the doctors gastroenterologists? Third you need to research celiac disease. Yes, you can be asymptomatic, but could still have instestinal damage as the small intestine is vast. here is a good place to start: http://www.cureceliacdisease.org/screening/ You might think you are a silent celiac, but ever been anemic? Had your bones checked?

That's good to know about Texas Children's, unfortunately I don't believe they accept our insurance. Our former pediatrician joined with one of their medical groups and we had to find a new one due to insurance. I'll check out their site though.

9 months ago I went to my doctor for normal blood work. She called me to tell me everything looked great, but o yeah, my gluten sensitivity levels were extremely high. I should probably stop eating gluten since it looks like I have celiac. She hung up and I never heard from her again. I cut out gluten completely, even though I have never experienced one single symptom of celiac. 9 months later, I decided to reach out to another doctor to get a second opinion, as I experienced absolutely zero change on 9 months of strict gluten free diet. All this doctor did was request the results from the previous doctor, tell me it is confirmed I have celiac, and hung up the phone. This angers me tremendously on two counts. One, I have absolutely zero symptoms of celiac, and would NEVER know if I was "glutened". Two, the complete lack of information or support from both doctors is horrifying to me. And finally, I simply do not believe the diagnosis and as considering just starting to eat a normal diet again. I would never know the difference. I am really just venting because this situation upsets me so much, and I have suffered mentally and socially from going gluten free. Since I have absolutely zero symptoms, even if I was actually celiac, I highly doubt anything would ever come of it if I continued to eat gluten. I could just pretend I never heard from either terrible doctor and go on living my life. Someone has to have been in the same situation as me, right?
