Do Vitamin D Deficiency, Gut Bacteria, and Gluten Combine in Infancy to Cause Celiac Disease?

This article appeared in the Summer 2008 edition of Celiac.com's Scott-Free Newsletter.

Celiac.com 06/16/2008 - Do vitamin D deficiency, gut bacteria, and timing of gluten introduction during infancy all combine to initiate the onset of celiac disease? Two recent papers raise the potential that this indeed may be the case. One paper finds that when transgenic mice expressing the human DQ8 heterodimer (a mouse model of celiac disease) are mucosally immunized with gluten co-administered with Lactobacillus casei bacteria, the mice exhibit an enhanced and increased immune response to gluten compared to the administration of gluten alone.[1] A second paper finds that vitamin D receptors expressed by intestinal epithelial cells are involved in the suppression of bacteria-induced intestinal inflammation in a study which involved use of germ-free mice and knockout mice lacking vitamin D receptors exposed to both friendly and pathogenic strains of gut bacteria.[2] Pathogenic bacteria caused increased expression of vitamin D receptors in epithelial cells. Friendly bacteria did not.

If one considers these two papers together, one notices: (1) Certain species of gut bacteria may work in conjunction with gluten to cause an increased immune response which initiates celiac disease; (2) The presence of an adequate level of vitamin D may suppress the immune response to those same gut bacteria in such a way as to reduce or eliminate the enhanced immune response to gluten caused by those gut bacteria, thus preventing the onset of celiac disease.

Vitamin D has recently been demonstrated to play a role in preserving the intestinal mucosal barrier. A Swedish study found children born in the summer, likely introduced to gluten during winter months with minimal sunlight, have a higher incidence of celiac disease strongly suggesting a relationship to vitamin D deficiency.[3] Recent studies found vitamin D supplementation in infancy and living in world regions with high ultraviolet B irradiance both result in a lower incidence of type 1 diabetes, an autoimmune disease closely linked to celiac disease.[4][5]

Gut bacteria have long been suspected as having some role in the pathogenesis of celiac disease. In 2004, a study found rod-shaped bacteria attached to the small intestinal epithelium of some untreated and treated children with celiac disease, but not to the epithelium of healthy controls.[6][7] Prior to that, a paper published on Celiac.com[8] first proposed that celiac disease might be initiated by a T cell immune response to "undigested" gluten peptides found inside of pathogenic gut bacteria which have "ingested" short chains of gluten peptides resistant to breakdown. The immune system would have no way of determining that the "ingested" gluten peptides were not a part of the pathogenic bacteria and, thus, gluten would be treated as though it were a pathogenic bacteria. The new paper cited above[1] certainly gives credence to this theory.

Celiac disease begins in infancy. Studies consistently find the incidence of celiac disease in children is the same (approximately 1%) as in adults. The incidence does not increase throughout life, meaning, celiac disease starts early in life. Further, in identical twins, one twin may get celiac disease, and the other twin may never experience celiac disease during an entire lifetime. Something other than genetics differs early on in the childhood development of the twins which initiates celiac disease. Differences in vitamin D levels and the makeup of gut bacteria in the twins offers a reasonable explanation as to why one twin gets celiac disease and the other does not. Early childhood illnesses and antibiotics could also affect vitamin D level and gut bacteria makeup. Pregnant and nursing mothers also need to maintain high levels of vitamin D for healthy babies.

This is a very interesting theory, new to my ears at the very least. I liked it.

Two years ago I was taking Emergen-C vitamin packets on a daily basis without being aware that some of the flavors contain wheat. I became very sick to the point of losing weight. Ever since I have been having major gut problems that wouldn't go away. I had ultrasound to look at my appendix and ovaries and I had upper and lower endoscopy. Thankfully nothing of interest but the diarrhea would not go away. My sister suggested that I have my vitamin D levels checked which I did. 29 ng/ mL despite having been in the sun. This is within the supposed normal range but I started supplementing with Vitamin D3 and my gut problems cleared up. It's been two months and I'm doing great. (And no more acne!)

People interested in supplementing with vitamin D should google 'Vitamin D Council' for lots of information. Researchers are suggesting raising the RDA for vitamin D. Also there are interesting questions about what the upper limits for Vitamin D intake should be. Apparently the research on vitamin D toxicity is very limited and questionable in it's validity.

My son is wheat sensitive and now I think I will add more Vitamin D to his diet also... He was put on Soy formula at a very early age as I was unable to breast feed and regular formula made him vomit. He has no milk allergies. Perhaps this early exposure to gluten, along with the fact that he had antibiotics at least twice before he was a year old has created this for him.

I am vitamin D deficient since childhood and gluten allergy was detected quite late in life (early 30's). This is very helpful to know that deficiency of vitamin D may have caused this allergy to me. I will increase my vitamin D intake and report back.

Thank you so much. 8-12 weeks! Oh my goodness, I don't think I can do that. I think going gluten-free made my body's defenses go down or something. I felt bad before, but reintroducing it was completely awful! I still feel queezy a few days later. Let's pray it just comes back positive. lol

Thanks for the feedback! Gemini you're very right - surgery was a totally weird recommendation. My current doctor treated me without hormones because my TSH levels are normal. The doctor found that my Vitamin D levels were severely low and put me on a high dose. They climbed just out of the deficient range. I am very active and frequently outdoors, and they still only climb out of deficient If i'm on intensive VIitamin D supplementation. - In addition, She also suggested I a modified lower carb diet (I'm at a healthy weight, there was no reduction in calories, just an increase in protein and fat and a reduction in carbs, a low reduction, slightly above the recommendations for a diabetic), which the doctor recommended for PCOS. Both of these coincided correlated with a slight reduction in the anti-thyroid antibodies and a slight reduction in nodule size. My TSH levels have remained stable, so it was incorrect to say function, really just a reduction in the level of attack (but the thyroid levels are still high). The doctor that recommended surgery did so because "you're about to start college and you won't have time for monitoring, it will eventually fail. If we remove it now, you can just go on Synthroid and you'll never have to deal with the levels being out of whack." Yeah.... I was 18 then.... I'm now 27, but my Mom just went "NOPE!" and got a second opinion. This person was fine, but all he did was monitor to make sure the TSH levels stayed ok. They did, I just have a goiter and several nodules. The most recent endo. I've seen, who put me on intensive Vitamin D therapy and worked with me on the diet, felt like she was thorough (again minus completely dismissing the first celiac results. I think the D supplementation and diet were associated with a decrease (but obviously didn't and really couldn't reverse the outcome of the disease) in antibodies and nodule size because my TSH levels have yet to get out of whack. I also wonder if with fewer carbs, I ate less (thought still too much If I'm celiac) gluten, and that could have been more a factor in the correlation. Gemini- I'm glad that you have found a good treatment that keeps your levels where they need to be! I also really appreciate the welcome. Update: I have a referral to a GI specialist! I don't want to have Celiac... I love to travel, and I'm very social. I live in the US but my family is from Uruguay, South America, so I carry this Latin Cultural thing about loving to share food and seeing it as such a huge part of hospitality and community. I know that food in social settings gets hard to navigate...But I feel a sense of relief to think that I might have an answer to other health questions and that there is a way that I can stop or at least slow damage.

These can be sourced from various ingredients one being wheat. Please check with the manufacture of your products to figure out if they contain gluten or how they are made....and yes gluten in your makeup, and especially lotion, shower gel, etc is a huge issues. Consider this, gluten contamination can happen from gluten protein residue. How often would you touch your arms, hair, etc or use your hands and touch your food, plate, fork, spoon before putting it in your mouth? Do you bite your nails, sometimes pick up a mint or gum? Hate to say it this way but if you use gluten containing stuff like that shit will happen with cross contamination. Consider changing over to a dedicated gluten-free version of hygiene products and save your self the drama. I use EO products, The Seaweed Co, Savvy Naturals, Hugo Naturals, and Vaseline products products without issues personally.

I had an enlarged thyroid, but no nodules. Dr felt it and ultrasound confirmed. I had so many symptoms of hypothyroid- weight gain, fatigue, hoarse voice-couldn't yell or sing or swallow (still can't swallow, but mostly at the bottom end. Used to not be able to get it past my neck, either) brain fog so that I couldn't form a complete sentence or respond with any timeliness, cold all the time, etc. Dr was in his 70's and old school. He didn't do any further blood tests or anything. Just said to take iodine. So, I started taking iodine. By the next year, different dr, all my thyroid tests came back normal, it wasn't enlarged anymore and most of my symptoms were very much improved. Read "Iodine: Why you need it and can't live without it" Kinda boring and repetitive, but good info. Iodine Crisis by Lynne Farrow is also really good. (She talks more about breast cancer than thyroid. But, the iodine information & history is great.) https://www.amazon.com/Iodine-Need-Cant-Live-Without/dp/0966088239/ref=sr_1_1?ie=UTF8&qid=1493386200&sr=8-1&keywords=dr+brownstein+iodine+book

Ok can anyone please shed light on this subject! I been reading conflicting information. Do I really need to be concerned about products that contain these two ingredients in them like my face products and my body lotions and shower gels? If I'm not ingesting them can they really hurt me? Only been diagnosed for three weeks with celiac and I'm trying so hard to follow the guidelines but this seems to be a gray area. I also check on the list of unsafe ingredients and I don't see them listed there so whats the scoop? Safe or unsafe please help!!!!
