    TEN FACTS ABOUT CELIAC DISEASE GENETIC TESTING


    Dr. Scot Lewey

    Celiac.com 04/24/2008 - Genetic tests for celiac disease and gluten sensitivity are readily available. Testing can be performed on either blood and mouth swab samples. If the testing is performed by certain laboratories not only will you have quite an accurate prediction of your risk of Celiac disease but also you may have information about the statistical probability that your children will inherit the risk, your likelihood of more severe Celiac disease, whether one or both of your parents had the risk gene, and for some laboratories you may determine your risk of gluten sensitivity without Celiac disease.

    The absence of any portion of the high-risk genetic patterns DQ2 and DQ8 nearly excludes the possibility of celiac disease with an approximate accuracy of 99.9%. However, there is a big caveat about relying on "negative celiac genetic testing". To definitively declare you have negative celiac genetic tests requires that the laboratory test for and report the presence or absence of the entire HLA DQ genetic pattern, including both alpha and beta subunits. The DQ genetic patterns DQ2 and DQ8 have two subunits but some laboratories only test for the beta subunit. This DQ typing is complicated and difficult to understand even by physicians and scientists. I have written an updated detailed review that appears in the Spring 2008 issue of Scott-Free newsletter published by celiac.com.

    Data collected by Dr. Ken Fine of Enterolab has supported the well-known fact that the absence of DQ2 and DQ8 does not exclude the risk of being gluten intolerance or sensitive though it now generally believed that one or both of those genetic white blood cell patterns are required to develop the autoimmune disorder known as Celiac disease or Celiac Sprue. However, there is a new study that reports that being negative for DQ2 and DQ8 does not completely exclude the possibility of celiac disease, especially in men. Previous studies have well documented blood test negative Celiac Sprue, also more common in elderly men with long-standing severe disease. Since DQ2 or DQ8 is almost universally present with the specific blood tests tissue transglutaminase and anti-endomysial antibodies are present it is not surprising that individuals without DQ2 or DQ8 that are negative for these two blood tests are being reported that meet criteria for Celiac disease.

    These new studies are also providing further information that the genetics of Celiac is gender specific. If you are a man, your risk of celiac disease may be higher than a woman if you don't have the classic genetic patterns. Again, in this situation your blood tests may be negative. If you are a woman, the risk for Celiac disease is generally higher than a man, especially if you have received the at risk gene from your father instead of your mother.

    Celiac is arguably the most common autoimmune disease. It is very common. It is easily treated. It affects 1/100 people worldwide. However, most people with celiac disease (~90%) are unaware, undiagnosed or misdiagnosed. Most adults finally diagnosed with celiac disease have suffered at least 10-11 years and have seen more than 3 or more doctors. Genetic testing is not only available but can be extremely helpful in determining your risk of developing Celiac disease, how severe it may be and the risk of your family members. Don't be one of those whose diagnosis is missed or needlessly delayed for over a decade. Get tested! Learn about the genetic tests for Celiac disease and if necessary educate your doctor about this testing.

    Here are ten facts you should know and remember about Celiac genetic testing.

    1. Genetic testing can help determine your risk as well as your children's risk.
    2. Celiac genetic tests can be done on blood or a mouth swab sample but your doctor may be unaware of the tests, not know how to order them, or know how to interpret the results.
    3. Genetic testing is not affected by diet. You can be eating gluten or on a gluten free diet. Blood tests for celiac disease antibodies, however, need to be done while eating gluten. They can become negative within a few weeks of restricting gluten so if you are going to get the diagnostic antibody blood tests don't begin a gluten free or restricted diet before being tested.
    4. Some insurance companies do not for the Celiac genetic test and almost all who do require pre-authorization first. The following diagnostic codes are helpful when requesting insurance coverage: 579.0 (Celiac disease); V18.59 (family history of GI disease); and/or V84.89 (genetic susceptibility to disease).
    5. Some laboratories do not perform the all of the necessary components of the test to completely exclude the possible genetic risk of Celiac disease and most don't test for or report the other gluten sensitive DQ patterns. Before you accept that have a negative test you need to know if your test included both the alpha and beta subunits of HLA DQ or did they just perform the beta typing.
    6. In some rare individuals, especially some men, a negative genetic test may not exclude the possibility of celiac disease anymore than a negative blood test. Men more commonly have negative genetic tests and blood tests, especially older men with long-standing severe disease.
    7. Both the DQ type, and number of copies you have, matter when determining not only your risk but also the possible severity of celiac disease. Two copies of DQ2 carries more risk than one copy of DQ8 or only partial DQ2. Even a single copy of DQ2 alpha subunit ("half DQ2 positive") carries risk for celiac disease but most of the commonly used laboratories for Celiac genetics do not test for or report the presence of this component of the celiac genes.
    8. The absence of at risk genes DQ2 and/or DQ8 does not exclude the possibility of being gluten intolerant or sensitive. You may respond to a gluten free diet even if you don't have DQ2 or DQ8 or true autoimmune Celiac disease.
    9. You can get genetic testing without a doctor's order and the tests can be done without having blood drawn or insurance authorization if you are willing to pay between $150-400 (www.kimballgenetics.com and www.enterolab.com).
    10. Laboratories in the U.S. that are known to offer complete alpha and beta subunit genetic testing include Kimball Genetics, Prometheus, and LabCorp. Bonfils, Quest and Enterolab only test for the beta subunit portions and therefore their test can miss part of a minor alpha subunit that carries a risk of Celiac disease. A negative DQ2 and DQ8 report from these labs may not necessarily be truly negative for the risk of Celiac disease.

    Excellent: it explains why I am a severe celiac and yet am negative for the antibodies. I am a woman, northern European, Hispanic and Middle Eastern ethnicity and no previous known family history. My sons have tested negative for tTg and . My brother is negative for the tTg and antiendomyasial antibodies but has severe osteoporosis at 45 years of age, without any known risk factors. We need to do genetic testing!!

    I had seven endoscopies done only 2 of them with same doctor---rest all different--celiac came back negative--also blood test---I finally found a celiac doctor whom my daughter recommended--she also has celiac disease--she did a cheek swap and sure enough I have celiac disease and have had it for a few years. I started having stomach problems and had a hernia and a sphincter that didn't close--so this was the problem with my severe bile reflux and gerd. I developed scurvy a year before that and it took 3 months for doctors and a specialist to try and find out what it was. I had it very badly on my whole right leg. Discolored-blood collections under the skin---the hundreds of red dots-due to very low platelets- All of the symptoms I had visible and not and no one put it together. I kept suggesting it was a problem with malnutrition but no one listened. My stomach and throat were raw. Had all kinds of tests done---finally my oncologist told me to have a leg biopsy done and sure enough it came back as scurvy. A lot of damage was done to my digestive system. Also had my gallbladder removed-had a small stone--they thought this might have been the source of the reflux --I ended up with worse reflux. It took me 2 years to find a surgeon to do the fundoplication--I am a high risk patient--allergic to many, many,drugs---pump prohibitors gave me seizures-so I am unable to take anything for the gerd. thought all would end there--I still have reflux severely---weigh 93 pounds with many food allergies--casein, yeast all dairy and it goes on----no rice-my blood counts and platelets are always bad--high calcium--cysts now found on my thyroid and most probe my parathyroid glands--didn't show any if the x-rays but I have all the symtoms-kidney stone--I only have one kidney--donated the other to my sister in 1968. I live in pain every day--trying to cope---your articles help me a lot. Thank you.

    I am a Northern European lady and have family history of gluten sensitivity, I am gluten sensitive but do not have DQ2 OR DQ8 AND had one doctor at Mayo clinic telling me that it is 100% certain that I can't have Celiac disease.

    A gluten-free diet put my intestinal symptoms on the right track.

    I have a few concerns, I had a biopsy done in 10/08 and it tested negative for celiac disorder. However 7 months later I'm still having the same symptoms and now my doctor is saying that's not a guarantee (the biopsy) and there treating me as if I do have celiac now.

    Could you please provide some theories as to why older men who test negative for the celiac risk gene can actually have celiac.

    Thanks a lot. I was going to go with Enterolab until I read this article. Now I plan on testing with Kimball or Labcorp. However, I couldn't find any info on Kimball or Labcorp's websites which mentions alpha and beta subunit genetic testing. Are you sure they still offer this? Has anyone else here gotten these tests done?

    I just ordered the tests from Kimball (after seeing the special they're offering right now through this website) and am eagerly looking forward to getting the test and hearing the results. My 2 sisters and I all are showing signs of gluten sensitivity, but none of us has been officially diagnosed yet.

    Very informative, as a scientist and a celiac I am amazed how complex the genetic marking of celiac disease is. I would even dare to say that it would be easier to look for a gluten-tolerant marker and use the non-presence of this marker as an indicator of gluten related conditions! However, I am even more amazed at the very un-scientific diagnosis process that many 'doctors' follow. Too many people are reporting multiple misdiagnoses and inaccurate testing regimes. As a researcher (astrochemist) I would not trust these 'doctors' in my lab!

    I'm Celiac (finally correctly diagnosed in 2001) and have a son (he's 15) that has tested positive for Celiac on one of the blood test. He's had 2 blood tests. The doctor didn't want to do a biopsy so I opted to do genetic testing. I chose Prometheus to do it. It cost $509 and the test came back 'inconclusive' for Celiac. Does anyone know what that means? My doctor said that means that my son may get Celiac and he may not. I'm not thrilled that I spent $509 to find that out. I already knew that!

    Thank you for this article. I was recently diagnosed with celiac and could not figure out how I was going to get my kids tested (11 & 8 years) without a biopsy, especially as neither of them seem to have any real problems. This is a much better way of checking. My doctor uses Quest so will have to discuss either using one of the others or doing it myself. Thanks again!

    Thank you for this very informative article.

    I am a self diagnosed Coeliac…

    I had all the “classic†symptoms but was misdiagnosed by all the doctors that I've seen over a 13 year period!

    I have a sister that was properly diagnosed as Coeliac at 9 months old. At 15 years old, I had severe Anemia that didn't respond to any treatment, Fatigue, Nausea, terrible abdominal pains, weight gain etc but the doctors convinced me (and not my mum…) that I didn't have Coeliac based on a negative blood test and endoscopy.

    Finally, at 28, when the stomach pain attacks grew too close together I insisted on another blood test- which came out positive

    On the advice of my GP, I skipped the biopsy and started a gluten-free diet straight away. I had immediate positive affect on my overall health

    Since then, my 2 kids have been genetically tested. As they carry 1 gene only, the official result was “Coeliac disease cannot be ruled outâ€

    I chose to put them on a strict gluten-free diet, based on my experience. I just had a 3rd child and not even going to bother testing this time….

    My concern is regarding the effect of the 13 year long exposure to Gluten on the risk of bowl cancer

    If anyone could point me to some information regarding that I would appreciate it

    I'm so glad I read this article before choosing a lab. Turns out I have an alpha sub-unit that would not have been detected by labs only checking for the beta sub-unit.

    What I STRENUOUSLY object to in this article is the usage of the term "True Celiac Sprue." This is scientifically and practically a TOTAL MISNOMER. It persists in medicine because medical doctors have ZERO to fifteen minutes of training in Celiac Disease, and the so-called intellects in the field make this extremely artificial, unnnecessary, and wholly disparaging(to add to the already extant built-in disparagement in Celiac inherently)distinction in language that bears ZERO relation to REALITY. They do so in the name of science but cannot in fact justify their actions with sound comprehensive science, just as Lewey accurately acknowledges it is not possible to exclude a possible diagnosis of Celiac on the basis of negative genetic or blood antibody tests(or even BOTH those situations).

    On the positive side I do feel the article makes an important contribution to the gender designation generally supportive of the understanding that men have a harder time obtaining an affirmative diagnosis and some of the reasons for that--although one of the main reasons has nothing to do with medicine and everything to do with Sociollogic and even Socioeconomic factors in that society generally does not easily accept the notion that men should be designated easily as disabled or of a similarly suggestive adjective with regard to health issues, lest the very traditional basis of our society thus be undermined in its basic underpinnings---and this bias is clearly reflected in clinical medicine with relation to Celiac disease. The preference is always, in "acknowledging anything"--to rather conclude some kind of mental health problem, which serves numerous purposes, not the least of which is to minimize the medical aspects lest medical doctors have to accept as much responsibility for caring for such patients as Dr. Lewey has graciously dared to do in his professional life here. The doctors I saw with my disease were in Northern Colorado and over a span of four years' time during the middle 1980's--I did not get done to "The Springs" until I went there to see a woman Naturopath named Shields, who while evidently quite learned generally, also held out zero practical help with my experience of severe Celiac Sprue that took me down to a weight of 119 pounds at age 30 standing six feet two inches in height.

    So I feel I have reason to remain upset over the ignorance of the past, and indeed, while ignorance is not confined to relatively rural areas of the country like Colorado, I certainly encountered a whole bunch in that state vis-a-vis this Celiac thing. And so I commend Dr. Lewey for his "new breed" attitude, a refreshing and necessary element in improving the quality of care of that percentage of us in society he may in fact encounter in his practice.

    On the verge of desperation, after a lifetime of misery (I am 52) and a feces sample on helicobacter pylori which tested negative. I have a very pronounced suspicion for celiac disease. This even before I have discussed this with my physician, which I certainly shall. Thanks, Adi and Sharon Mackey, your contributions are valuable for me.

    I believe that my mother, who died of diabetes, probably had celiac disease. No one that I know of in my family had it, but then, where did I get it?? My daughter tested negative but we know she has it. She is OK as long as she avoids gluten.

    My 3 yr old just had the genetic tests done - and those results, according to the doctor, not only diagnosed my son but helped treat my daughter (7 yrs old)

    My daughter (7) was finally diagnosed with Celiac earlier this spring, after years of tummy issues dating back before she could walk. Her case is so severe, that 10 months on the strict diet haven't cleared up her diarrhea or tummy cramps.

    My son (3) has been "failure to thrive" since before he could walk, but tested negative against Celiac this spring.

    He finally started gaining weight when we began our gluten-free quest for my daughter. After 10 months of the gluten-free diet for him, he's finally at the 50% for his age/weight/stature.... I didn't think I'd ever see that number again.

    Our doctor ran the genetic test on my son & his results were the double DQ2 - the highest risk factor for Celiac, associated with the most severe symptoms.

    He firmly declared my son officially "Celaic" based on history of failure to thrive & then growing exponentially on the diet, paired with his genetic results.

    He also said this genetic pairing of double DQ2 is dominant, and is certain my daughter is the same way. We are bypassing several passive tests on her, and going straight for immunosuppressive therapy. We finally have a confident doctor, and finally have answers.

    Hi, celiac myself and wanting to make a difference in the world by helping others. I would like to know if you are interested in sharing your story. You say touch the life of another going threw the same thing. I am writing a book of people wrongly diagnosed. Could you help me please. I would love to share your story.

    Celiac.com 06/26/2007 - Celiac disease is one of the most common chronic health disorders in western countries. It is also one of the most under-diagnosed. Up until ten years ago, medical schools taught that celiac disease was relatively rare and only affected about 1 in 2,500 people. It was also thought to be a disease that primarily affected children and young people. Recent studies and advances in diagnosis show that at least 3 million Americans, or about 1 in 133 people have celiac disease, but only 1-in-4,700 is ever diagnosed.
    The National Institutes of Health shows the prevalence of celiac disease to other well-known conditions as follows:
    Celiac Disease affects 3 million Americans Epilepsy affects 2.8 million Americans Crohns Disease affects 500,000 Americans Ulcerative Colitis affects 500,000 Americans Multiple Sclerosis affects 333,000 Americans Cystic Fibrosis affects 30,000 Americans People with untreated celiac disease suffer intestinal damage when they eat products containing wheat, rye, or barley. The disease mostly affects people of European (especially Northern European) descent, but recent studies show that it also affects portions of the Hispanic, Black and Asian populations as well. Celiac disease presents a broad range of symptoms, from mild weakness and bone pain, to chronic diarrhea, abdominal bloating, and progressive weight loss. In most cases, treatment with a gluten-free diet leads to a full recovery from celiac disease. It is therefore imperative that the disease is quickly and properly diagnosed so it can be treated as soon as possible.
    If people with celiac disease continue to eat gluten, studies show that their risk of gastrointestinal cancer is 40 to 100 times that of the normal population. In addition to increased cancer risk, untreated celiac disease is associated with osteoporosis, and a two-fold increase in the risk of fractures, including first-time hip fractures. Moreover, an unusually high percentage of people with celiac disease suffer from the following related conditions (% in parenthesis):
    Anemia (3-6%) Arthritis (20%) Ataxia (40%) Cancer—Non-Hodgkins Lymphoma (39%) Cows Milk Intolerance (24%) Dermatitis (5%) Diabetes-Type 1 (12%) Irritable Bowel Syndrome (20%) Liver Disease (42%) Migraine Headaches (4%) Nerve Disease and/or Peripheral Neuropathy (51%) Obesity (30-40%) Osteoporosis (4.5%) Osteomalacia/Low Bone Density (70%) Pancreatic & Thyroid Disorders (5-14%) In fact, untreated celiac disease can actually cause or worsen some of these conditions, and medical guidelines now recommend celiac screening for all people with these conditions.
    The vast majority of people visit doctors who have been in practice for more than ten years, and for whom celiac disease is a rare condition and often not considered when handling complaints. Seniors are also more likely than the general population to suffer from conditions associated with celiac disease (Arthritis, Diabetes, Liver Disease, Osteoporosis, etc). Without awareness and screening, they are at greater risk for developing disorders resulting from celiac disease--many of which are avoidable with diagnosis and treatment. Awareness of celiac disease and related issues offers seniors and easy way to improve their health and wellbeing.

    This article appeared in the Spring 2007 edition of Celiac.coms Scott-Free Newsletter.
    Celiac.com 08/29/2007 - The XII International Celiac Disease Symposium, proudly hosted by the Celiac Disease Center at Columbia University, featured presentations from researchers from all over the globe. The last session of the scientific portion of the symposium, entitled “Non-Dietary Therapies”, was full of controversy and fireworks. Talks given by Drs. Khosla, Gray, Paterson, Anderson and Mitea all revealed that potential alternatives to the gluten free diet are now being aggressively pursued. Several groups have even spun off from pharmaceutical companies to raise funds to test these alternatives in patient trials. However, several questions remain. How close are we to a “pill” or “vaccine” to treat or prevent celiac disease? And do we even need, or more importantly, WANT them, given that the diet is safe and effective?
    Any alternative therapy for celiac disease must be at least as safe as the gluten-free diet, which, if done correctly, has NO side-effects. So the bar is raised very high. An alternative must offer great medical benefit to celiac patients without causing any medical harm. It is also unclear how, exactly, these new therapies will be implemented. Can they treat existing celiac disease? Will they prevent those at increased risk for the disease (such as siblings) from having symptoms? Will these medications allow celiac patients to ingest as much gluten as they want, or will they just take away the fear of contamination when eating questionable foods? What follows is a summary of several important points raised by some of these speakers in regard to the research that their center is doing in this area of “alternative therapies for celiac disease.
    Two groups discussed their research on what has commonly become known as “the celiac pill”. The idea behind the “pill” is somewhat similar to the idea of taking a lactase enzyme supplement to digest the milk sugar lactose (if you are lactose intolerant). However, digesting the proteins that trigger the immune reaction in celiac disease is much more complex than digesting the simple sugar found in dairy products. The small fragments of the gluten proteins from wheat, rye and barley, which stimulate the immune system in someone with celiac disease, contain a large quantity of an amino acid called proline. The stomach and pancreatic enzymes in humans have difficulty digesting the fractions where these prolines are located, making the gluten highly resistant to complete digestion. The idea behind the “celiac pill” is to provide enzymes to break down the gluten into smaller fragments which will not be recognized by a celiac patient’s immune system. Therefore, theoretically, gluten would not cause an immune reaction and could be safely eaten.
    Dr. Gary Gray, an adult gastroenterologist working at Stanford University in California, addressed this issue in his presentation “Oral Enzyme Therapy”. Their study looked at 20 biopsy-proven celiacs in remission (without symptoms) who received orange juice with either gluten or gluten pre-treated with a special enzyme (abbreviated PEP, for prolyl endopeptidase). Each patient consumed a low dose of gluten daily, 5 grams, which is equivalent to one slice of bread. The patients completed a daily symptom questionnaire, and had urine and stool tests of to measure intestinal damage. The researchers concluded that pretreatment of gluten with PEP avoided the development of fat or carbohydrate malabsorption in the majority of those patients who, after a 2-week gluten challenge, developed fat or carbohydrate malabsorption. The PEP enzyme needs to be investigated further in larger trials of celiac patients.
    Cristina Mitea, working with Dr. Fritz Koning at Leiden University in The Netherlands, also presented some data using similar technology, entitled “Enzymatic degradation of gluten in a GI-tract model”. This group published in 2006 that the above described PEP enzyme may not work optimally in the celiac patient, since it is not active at low stomach pH. The PEP enzyme may also be broken down by pepsin, a digestive enzyme in the stomach, before it reaches the small bowel where gluten causes the most damage. Given these facts, this group of researchers characterized a prolyl endoprotease enzyme, derived from the fungus Aspergillus niger, abbreviated AN-PEP. The AN-PEP enzyme, according to some publications, has been shown to work at stomach pH while resisting pepsin digestion. In the lab, the AN-PEP was able to degrade intact gluten as well as small fragments of gluten, including those that stimulate the immune system in patients with celiac disease. It also appeared to act within minutes, which is 60 times faster than PEP. This is particularly important, as ingested gluten will leave the stomach to enter the small bowel within 1 to 4 hours after being eaten. These researchers state that this enzyme is very stable, and could be produced at low cost at food-grade quality in an industrial setting. However, it has not yet been tested in human clinical studies.
    In summary, some of these future potential treatments include:

    I would hate to add up all the hundreds of dollars I have wasted trying to get healthy.  Now, however, I get healthy by focusing on one thing:  making my intestines healthy.  If my intestines are healthy, I can absorb food.  If I can absorb food, my body will be receiving the nutrition it needs to function, and thus I will be healthy.
    Of course, rule number one for all of us is to stay gluten free.  But, focusing on avoidance alone, can get depressing.  Instead, I like to focus on what I can do to strengthen my digestive system.  That way, all the good gluten free food I am consuming can actually benefit my body.  What good is eating healthy if you are unable to absorb the nutrients?  Pouring healthy food into a compromised gut would be as wasteful as pouring dollar bills over an ATM machine and hoping in vain to strengthen your bank account balance.
    Research shows that those of us with celiac disease/gluten intolerance often have decreased absorption despite following a strict gluten free diet.  Scott Adams summarized one of these articles on the celiac.com website back in 2003.  The article by Lee SK, et al. entitled “Duodenal Histology in Patients with Celiac Disease after Treatment with a Gluten-free Diet” implied that even though patients may feel better on a gluten-free diet, there may still be damaged intestinal areas that are incapable of optimal nutrient absorption.  Since specific nutrients are absorbed along specific locations in the small intestine, this can have long-term ramifications.  For instance, the proximal portion of the intestine is the site for absorption of vitamin B6 (pyroxidine).  If that portion is damaged, there will be decreased absorption, and your body will be deficient in B6.  You may then experience a range of neurological symptoms such as nervousness, irritability, and shakiness.  And, as happened in my case, you may see a doctor, only to be told you are having anxiety attacks and be handed a prescription for a mild tranquilizer.  Thankfully, I discovered that a good B6 supplement (Solgar “Magnesium with B6”) was all I needed and threw away the offending prescription, but this serves as an excellent—albeit oversimplified—example as to why we have to focus on improving the health of our intestines.
    Before I go on, I do want to say that the products listed below do not benefit me financially in the least.  Additionally, these are the products that work best for my body.  You may find a different brand works better for you, but as long as our focus is on getting those intestines healthy, we are all heading in the right direction!
    So, read on about what I personally consider the top four intestinal healing supplements…
    The first and best all-round product I have found that truly aids in restoring the intestinal lining is a glutamine supplement put out by a company called Metagenics.  The supplement, called “Glutagenics”, contains glutamine, licorice root, and aloe vera.  While studying for my masters in nutrition at Texas A&M University, we learned that glutamine is a key amino acid that aids in restoring the intestinal lining in patients that are transitioning from being tube-fed to a normal diet.   So, when my own chiropractor suggested this supplement and mentioned it contained glutamine, I purchased it and have been taking it on and off for three years.  
    Glutagenics is available online through various websites that carry the Metagenics brand. The supplement is unfortunately a bit cost prohibitive, but you can shop around for other brands that contain a similar blend, or buy the three active ingredients separately. Unfortunately, this did not work for me (I have an expensive gut), but it may for you.
    The next product is a good omega-3 fatty acid. Omega-3 fatty acids have so many benefits that even if you weren’t working on building up your intestines, they would still be beneficial. During my graduate research, I was fortunate to be part of an ongoing study on the mechanism whereby omega-3 fatty acids reduce the inflammatory response. Obviously, when our intestines are damaged, there is plenty of inflammation. So, including omega-3 fatty acids in our diet is vital.
    Thankfully, omega-3 fatty acids are getting easier and easier to come by. My family eats the high omega-3 brand eggs and the Smart Balance peanut butter and butter spreads. You can also purchase wonderful oil blends by Nordic Naturals. My favorite is the lemon-flavored Omega-3 liquid. The lemon flavor truly masks the fishy taste and even my children swallow the oil with minimal grumbling. Nordic Naturals is quite expensive (around $20.00 for 8 oz) but if you compare the amount of DHA you are getting per serving, it is definitely the most DHA for your dollar!
    Another great healing nutrient is zinc. Zinc is wonderful for wound healing- you’ll see it in many topical creams, but it also helps restore the intestines. Metagenics puts out a great supplement and their products are great for sensitive individuals. I find that 10mg works best for me. I don’t take it every day – too much will give you a bad taste in your mouth. Once I get that bad taste, I know I need to go off it for awhile.
    Finally (for now), find a great probiotic. The one that everyone recommends, by Garden of Life, contains wheat grass, so we have to avoid it. I do extremely well, however, on a product called Lacidophil by Xymogen. My energy levels actually improve on this brand. Xymogen has their own website where you can purchase products directly. Taking a good probiotic restores a healthy balance to your gut flora, which aids in overall health and digestion. I have just recently ordered one from Emerson Ecologics through a natural doctor and it’s supposed to be even better. It has many more strains of the good bacteria so I’m going to try it as soon as it comes in.
    Of the four products listed above, the two that I take daily are the probiotic and omega-3 oil. The other two I take on an ‘as-I-need-it’ basis.
    Unfortunately, our bodies don’t tolerate a lot of extra supplements, so go slowly and only add one at a time. Keep track of how you feel. You may never tolerate the mass quantities that some companies will try to sell you. But, since you are your own best manager, work with yourself slowly and patiently and you will find your health improves over time.
    May God bless you with the wisdom and discernment you need to live a healthy and vibrant life!

    Celiac.com 04/20/2018 - A digital media company and a label data company are teaming up to help major manufacturers target, reach and convert their desired shoppers based on dietary needs, such as gluten-free diet. The deal could bring synergy in emerging markets such as the gluten-free and allergen-free markets, which represent major growth sectors in the global food industry. 
    Under the deal, personalized digital media company Catalina will be joining forces with Label Insight. Catalina uses consumer purchases data to target shoppers on a personal base, while Label Insight works with major companies like Kellogg, Betty Crocker, and Pepsi to provide insight on food label data to government, retailers, manufacturers and app developers.
    "Brands with very specific product benefits, gluten-free for example, require precise targeting to efficiently reach and convert their desired shoppers,” says Todd Morris, President of Catalina's Go-to-Market organization, adding that “Catalina offers the only purchase-based targeting solution with this capability.” 
    Label Insight’s clients include food and beverage giants such as Unilever, Ben & Jerry's, Lipton and Hellman’s. Label Insight technology has helped the Food and Drug Administration (FDA) build the sector’s very first scientifically accurate database of food ingredients, health attributes and claims.
    Morris says the joint partnership will allow Catalina to “enhance our dataset and further increase our ability to target shoppers who are currently buying - or have shown intent to buy - in these emerging categories,” including gluten-free, allergen-free, and other free-from foods.
    The deal will likely make for easier, more precise targeting of goods to consumers, and thus provide benefits for manufacturers and retailers looking to better serve their retail food customers, especially in specialty areas like gluten-free and allergen-free foods.

    Celiac.com 04/19/2018 - Previous genome and linkage studies indicate the existence of a new disease triggering mechanism that involves amino acid metabolism and nutrient sensing signaling pathways. In an effort to determine if amino acids might play a role in the development of celiac disease, a team of researchers recently set out to investigate if plasma amino acid levels differed among children with celiac disease compared with a control group.
     
    The research team included Åsa Torinsson Naluai, Ladan Saadat Vafa, Audur H. Gudjonsdottir, Henrik Arnell, Lars Browaldh, and Daniel Agardh. They are variously affiliated with the Institute of Biomedicine, Department of Microbiology & Immunology, Sahlgrenska Academy, University of Gothenburg, Gothenburg, Sweden; the Institute of Clinical Sciences, Sahlgrenska Academy at the University of Gothenburg, Gothenburg, Sweden; the Department of Pediatric Gastroenterology, Hepatology and Nutrition, Karolinska University Hospital and Division of Pediatrics, CLINTEC, Karolinska Institute, Stockholm, Sweden; the Department of Clinical Science and Education, Karolinska Institute, Sodersjukhuset, Stockholm, Sweden; the Department of Mathematical Sciences, Chalmers University of Technology, Gothenburg, Sweden; the Diabetes & Celiac Disease Unit, Department of Clinical Sciences, Lund University, Malmö, Sweden; and with the Nathan S Kline Institute in the U.S.A.
    First, the team used liquid chromatography-tandem mass spectrometry (LC/MS) to analyze amino acid levels in fasting plasma samples from 141 children with celiac disease and 129 non-celiac disease controls. They then crafted a general linear model using age and experimental effects as covariates to compare amino acid levels between children with celiac disease and non-celiac control subjects.
    Compared with the control group, seven out of twenty-three children with celiac disease showed elevated levels of the the following amino acids: tryptophan; taurine; glutamic acid; proline; ornithine; alanine; and methionine.
    The significance of the individual amino acids do not survive multiple correction, however, multivariate analyses of the amino acid profile showed significantly altered amino acid levels in children with celiac disease overall and after correction for age, sex and experimental effects.
    This study shows that amino acids can influence inflammation and may play a role in the development of celiac disease.

    Celiac.com 04/18/2018 - To the relief of many bewildered passengers and crew, no more comfort turkeys, geese, possums or other questionable pets will be flying on Delta or United without meeting the airlines' strict new requirements for service animals.
    If you’ve flown anywhere lately, you may have seen them. People flying with their designated “emotional support” animals. We’re not talking genuine service animals, like seeing eye dogs, or hearing ear dogs, or even the Belgian Malinois that alerts its owner when there is gluten in food that may trigger her celiac disease.
    Now, to be honest, some of those animals in question do perform a genuine service for those who need emotional support dogs, like veterans with PTSD.
    However, many of these animals are not service animals at all. Many of these animals perform no actual service to their owners, and are nothing more than thinly disguised pets. Many lack proper training, and some have caused serious problems for the airlines and for other passengers.
    Now the major airlines are taking note and introducing stringent requirements for service animals.
    Delta was the first to strike. As reported by the New York Times on January 19: “Effective March 1, Delta, the second largest US airline by passenger traffic, said it will require passengers seeking to fly with pets to present additional documents outlining the passenger’s need for the animal and proof of its training and vaccinations, 48 hours prior to the flight.… This comes in response to what the carrier said was a 150 percent increase in service and support animals — pets, often dogs, that accompany people with disabilities — carried onboard since 2015.… Delta said that it flies some 700 service animals a day. Among them, customers have attempted to fly with comfort turkeys, gliding possums, snakes, spiders, and other unusual pets.”
    Fresh from an unsavory incident with an “emotional support” peacock incident, United Airlines has followed Delta’s lead and set stricter rules for emotional support animals. United’s rules also took effect March 1, 2018.
    So, to the relief of many bewildered passengers and crew, no more comfort turkeys, geese, possums or other questionable pets will be flying on Delta or United without meeting the airlines' strict new requirements for service and emotional support animals.

    WHAT IS CELIAC DISEASE?
    Celiac disease is an autoimmune condition that affects around 1% of the population. People with celiac disease suffer an autoimmune reaction when they consume wheat, rye or barley. The immune reaction is triggered by certain proteins in the wheat, rye, or barley, and, left untreated, causes damage to the small, finger-like structures, called villi, that line the gut. The damage occurs as shortening and villous flattening in the lamina propria and crypt regions of the intestines. The damage to these villi then leads to numerous other issues that commonly plague people with untreated celiac disease, including poor nutritional uptake, fatigue, and myriad other problems.
    Celiac disease mostly affects people of Northern European descent, but recent studies show that it also affects large numbers of people in Italy, China, Iran, India, and numerous other places thought to have few or no cases.
    Celiac disease is most often uncovered because people experience symptoms that lead them to get tests for antibodies to gluten. If these tests are positive, then the people usually get biopsy confirmation of their celiac disease. Once they adopt a gluten-free diet, they usually see gut healing, and major improvements in their symptoms. 
    CLASSIC CELIAC DISEASE SYMPTOMS
    Symptoms of celiac disease can range from the classic features, such as diarrhea, upset stomach, bloating, gas, weight loss, and malnutrition, among others.
    LESS OBVIOUS SYMPTOMS
    Celiac disease can often less obvious symptoms, such fatigue, vitamin and nutrient deficiencies, anemia, to name a few. Often, these symptoms are regarded as less obvious because they are not gastrointestinal in nature. You got that right, it is not uncommon for people with celiac disease to have few or no gastrointestinal symptoms. That makes spotting and connecting these seemingly unrelated and unclear celiac symptoms so important.
    NO SYMPTOMS
    Currently, most people diagnosed with celiac disease do not show symptoms, but are diagnosed on the basis of referral for elevated risk factors. 

    CELIAC DISEASE VS. GLUTEN INTOLERANCE
    Gluten intolerance is a generic term for people who have some sort of sensitivity to gluten. These people may or may not have celiac disease. Researchers generally agree that there is a condition called non-celiac gluten sensitivity. That term has largely replaced the term gluten-intolerance. What’s the difference between celiac disease and non-celiac gluten-sensitivity? 
    CELIAC DISEASE VS. NON-CELIAC GLUTEN SENSITIVITY (NCGS)
    Gluten triggers symptoms and immune reactions in people with celiac disease. Gluten can also trigger symptoms in some people with NCGS, but the similarities largely end there.

    There are four main differences between celiac disease and non-celiac gluten sensitivity:
    No Hereditary Link in NCGS
    Researchers know for certain that genetic heredity plays a major role in celiac disease. If a first-degree relative has celiac disease, then you have a statistically higher risk of carrying genetic markers DQ2 and/or DQ8, and of developing celiac disease yourself. NCGS is not known to be hereditary. Some research has shown certain genetic associations, such as some NCGS patients, but there is no proof that NCGS is hereditary. No Connection with Celiac-related Disorders
    Unlike celiac disease, NCGS is so far not associated with malabsorption, nutritional deficiencies, or a higher risk of autoimmune disorders or intestinal malignancies. No Immunological or Serological Markers
    People with celiac disease nearly always test positive for antibodies to gluten proteins. Researchers have, as yet, identified no such antobodies or serologic markers for NCGS. That means that, unlike with celiac disease, there are no telltale screening tests that can point to NCGS. Absence of Celiac Disease or Wheat Allergy
    Doctors diagnose NCGS only by excluding both celiac disease, an IgE-mediated allergy to wheat, and by the noting ongoing adverse symptoms associated with gluten consumption. WHAT ABOUT IRRITABLE BOWEL SYNDROME (IBS) AND IRRITABLE BOWEL DISEASE (IBD)?
    IBS and IBD are usually diagnosed in part by ruling out celiac disease. Many patients with irritable bowel syndrome are sensitive to gluten. Many experience celiac disease-like symptoms in reaction to wheat. However, patients with IBS generally show no gut damage, and do not test positive for antibodies to gliadin and other proteins as do people with celiac disease. Some IBS patients also suffer from NCGS.

    To add more confusion, many cases of IBS are, in fact, celiac disease in disguise.

    That said, people with IBS generally react to more than just wheat. People with NCGS generally react to wheat and not to other things, but that’s not always the case. Doctors generally try to rule out celiac disease before making a diagnosis of IBS or NCGS. 
    Crohn’s Disease and celiac disease share many common symptoms, though causes are different.  In Crohn’s disease, the immune system can cause disruption anywhere along the gastrointestinal tract, and a diagnosis of Crohn’s disease typically requires more diagnostic testing than does a celiac diagnosis.  
    Crohn’s treatment consists of changes to diet and possible surgery.  Up to 10% of Crohn's patients can have both of conditions, which suggests a genetic connection, and researchers continue to examine that connection.
    Is There a Connection Between Celiac Disease, Non-Celiac Gluten Sensitivity and Irritable Bowel Syndrome? Large Number of Irritable Bowel Syndrome Patients Sensitive To Gluten Some IBD Patients also Suffer from Non-Celiac Gluten Sensitivity Many Cases of IBS and Fibromyalgia Actually Celiac Disease in Disguise CELIAC DISEASE DIAGNOSIS
    Diagnosis of celiac disease can be difficult. 

    Perhaps because celiac disease presents clinically in such a variety of ways, proper diagnosis often takes years. A positive serological test for antibodies against tissue transglutaminase is considered a very strong diagnostic indicator, and a duodenal biopsy revealing villous atrophy is still considered by many to be the diagnostic gold standard. 
    But this idea is being questioned; some think the biopsy is unnecessary in the face of clear serological tests and obvious symptoms. Also, researchers are developing accurate and reliable ways to test for celiac disease even when patients are already avoiding wheat. In the past, patients needed to be consuming wheat to get an accurate test result. 
    Celiac disease can have numerous vague, or confusing symptoms that can make diagnosis difficult.  Celiac disease is commonly misdiagnosed by doctors. Read a Personal Story About Celiac Disease Diagnosis from the Founder of Celiac.com Currently, testing and biopsy still form the cornerstone of celiac diagnosis.
    TESTING
    There are several serologic (blood) tests available that screen for celiac disease antibodies, but the most commonly used is called a tTG-IgA test. If blood test results suggest celiac disease, your physician will recommend a biopsy of your small intestine to confirm the diagnosis.
    Testing is fairly simple and involves screening the patients blood for antigliadin (AGA) and endomysium antibodies (EmA), and/or doing a biopsy on the areas of the intestines mentioned above, which is still the standard for a formal diagnosis. Also, it is now possible to test people for celiac disease without making them concume wheat products.

    BIOPSY
    Until recently, biopsy confirmation of a positive gluten antibody test was the gold standard for celiac diagnosis. It still is, but things are changing fairly quickly. Children can now be accurately diagnosed for celiac disease without biopsy. Diagnosis based on level of TGA-IgA 10-fold or more the ULN, a positive result from the EMA tests in a second blood sample, and the presence of at least 1 symptom could avoid risks and costs of endoscopy for more than half the children with celiac disease worldwide.

    WHY A GLUTEN-FREE DIET?
    Currently the only effective, medically approved treatment for celiac disease is a strict gluten-free diet. Following a gluten-free diet relieves symptoms, promotes gut healing, and prevents nearly all celiac-related complications. 
    A gluten-free diet means avoiding all products that contain wheat, rye and barley, or any of their derivatives. This is a difficult task as there are many hidden sources of gluten found in the ingredients of many processed foods. Still, with effort, most people with celiac disease manage to make the transition. The vast majority of celiac disease patients who follow a gluten-free diet see symptom relief and experience gut healing within two years.
    For these reasons, a gluten-free diet remains the only effective, medically proven treatment for celiac disease.
    WHAT ABOUT ENZYMES, VACCINES, ETC.?
    There is currently no enzyme or vaccine that can replace a gluten-free diet for people with celiac disease.
    There are enzyme supplements currently available, such as AN-PEP, Latiglutetenase, GluteGuard, and KumaMax, which may help to mitigate accidental gluten ingestion by celiacs. KumaMax, has been shown to survive the stomach, and to break down gluten in the small intestine. Latiglutenase, formerly known as ALV003, is an enzyme therapy designed to be taken with meals. GluteGuard has been shown to significantly protect celiac patients from the serious symptoms they would normally experience after gluten ingestion. There are other enzymes, including those based on papaya enzymes.

    Additionally, there are many celiac disease drugs, enzymes, and therapies in various stages of development by pharmaceutical companies, including at least one vaccine that has received financial backing. At some point in the not too distant future there will likely be new treatments available for those who seek an alternative to a lifelong gluten-free diet. 

    For now though, there are no products on the market that can take the place of a gluten-free diet. Any enzyme or other treatment for celiac disease is intended to be used in conjunction with a gluten-free diet, not as a replacement.

    ASSOCIATED DISEASES
    The most common disorders associated with celiac disease are thyroid disease and Type 1 Diabetes, however, celiac disease is associated with many other conditions, including but not limited to the following autoimmune conditions:
    Type 1 Diabetes Mellitus: 2.4-16.4% Multiple Sclerosis (MS): 11% Hashimoto’s thyroiditis: 4-6% Autoimmune hepatitis: 6-15% Addison disease: 6% Arthritis: 1.5-7.5% Sjögren’s syndrome: 2-15% Idiopathic dilated cardiomyopathy: 5.7% IgA Nephropathy (Berger’s Disease): 3.6% Other celiac co-morditities include:
    Crohn’s Disease; Inflammatory Bowel Disease Chronic Pancreatitis Down Syndrome Irritable Bowel Syndrome (IBS) Lupus Multiple Sclerosis Primary Biliary Cirrhosis Primary Sclerosing Cholangitis Psoriasis Rheumatoid Arthritis Scleroderma Turner Syndrome Ulcerative Colitis; Inflammatory Bowel Disease Williams Syndrome Cancers:

    Celiac.com 04/17/2018 - Could the holy grail of gluten-free food lie in special strains of wheat that lack “bad glutens” that trigger the celiac disease, but include the “good glutens” that make bread and other products chewy, spongey and delicious? Such products would include all of the good things about wheat, but none of the bad things that might trigger celiac disease.
    A team of researchers in Spain is creating strains of wheat that lack the “bad glutens” that trigger the autoimmune disorder celiac disease. The team, based at the Institute for Sustainable Agriculture in Cordoba, Spain, is making use of the new and highly effective CRISPR gene editing to eliminate the majority of the gliadins in wheat.
    Gliadins are the gluten proteins that trigger the majority of symptoms for people with celiac disease.
    As part of their efforts, the team has conducted a small study on 20 people with “gluten sensitivity.” That study showed that test subjects can tolerate bread made with this special wheat, says team member Francisco Barro. However, the team has yet to publish the results.
    Clearly, more comprehensive testing would be needed to determine if such a product is safely tolerated by people with celiac disease. Still, with these efforts, along with efforts to develop vaccines, enzymes, and other treatments making steady progress, we are living in exciting times for people with celiac disease.
    It is entirely conceivable that in the not-so-distant future we will see safe, viable treatments for celiac disease that do not require a strict gluten-free diet.
