    ABSTRACT: BACKGROUND AND AIMS - Celiac disease is associated with several autoimmune disorders such as insulin-dependent diabetes, Sjogrens syndrome, Addisons disease and thyroid diseases. The aim of our study was to evaluate the prevalence of celiac disease in patients affected by autoimmune thyroid diseases by means of anti-gliadin and anti-endomysial antibodies. PATIENTS: We studied 92 patients affected by autoimmune thyroid diseases (47 chronic autoimmune thyroiditis, 22 Hashimotos thyroiditis and 23 Graves disease). Ninety patients with non autoimmune thyroid disorders (51 multifollicular goitre, 28 solitary nodule and 11 papillary carcinoma) and 236 blood donors also took part in the study as control groups. METHODS: Total serum IgA were measured in all subjects to exclude selective IgA deficiency; then we measured anti-gliadin antibodies and anti-endomysial antibodies. In patients with anti-gliadin/anti-endomysial antibody positivity and/or with haematinic and laboratory signs of malabsorption we carried out gastrointestinal endoscopy with duodenal histological examination.

    RESULTS: Among the 92 patients with autoimmune thyroid disease, 4 (4.3%) showed anti-gliadin and anti-endomysial positivity and had celiac disease; among the 90 patients with non autoimmune thyroid diseases, 1 (1.1%) had celiac disease; finally, among the blood donors, 1 subject (0.4%) was anti-gliadin-anti-endomysium antibody positive and had celiac disease. Those subjects presenting with only anti-gliadin antibody positivity did not have celiac disease.

    CONCLUSIONS: These results show that the prevalence of celiac disease in patients with autoimmune thyroid diseases is significantly increased when compared with the general population (p = 0.009) but not with patients affected by non autoimmune thyroid disorders (p = 0.18). We suggest a serological screening for celiac disease in all patients with autoimmune thyroid disease measuring anti-endomysial antibodies, considering that early detection and treatment of celiac disease are effective in preventing its complications.

    Dig Dis Sci 2000;45:403-406.
    (Celiac.com 04/10/2000) Italian researcher Dr. Tarcisio Not, of Clinica Pediatrica, I.R.C.C.S., Trieste, and colleagues, have concluded that a relatively high percentage of patients with autoimmune thyroiditis also have celiac disease. They studied 172 patients who had autoimmune thyroid disorders, and two control groups. Their control groups were comprised of 498 patients with other diseases, and 4,000 healthy patients. The method used by the researchers was a blood test that looks for IgA-class endomysium antibodies using immunofluorescence.
    Their results, which were published in the February issue of Digestive Diseases and Sciences, show that the prevalence of celiac disease is 3.4% in patients with autoimmune thyroiditis, compared with 0.6% and 0.25% among the two control groups. They also found a connection between untreated celiac disease, gluten consumption, and autoimmune disorders. The researchers believe that undiagnosed celiac disease can cause other disorders by switching on some as yet unknown immunological mechanism. Untreated celiac patients produce organ-specific autoantibodies. Further, By following these subjects longitudinally, it has been seen that not only do the anti-gliadin antibodies and anti-endomysium antibodies disappear after 3 to 6 months of a gluten-free diet, but so do the organ-specific autoantibodies.
    In conclusion the Italian researchers suggest that patients with autoimmune thyroiditis could benefit from a screening for celiac disease, which could eliminate the symptoms and limit the risk of developing other autoimmune disorders.

    Celiac.com 11/25/2008 - Celiac disease is one of the most under-diagnosed medical disorders, with 97% of all cases currently remaining undiagnosed. According to the National Institutes of Health, 3 million people in theUnited States with celiac disease, while only 140,000 have beendiagnosed. Celiac disease ismore than twice as common in people over 50 years of age.
    People with untreated celiac disease are at risk of developing anynumber of associated conditions, including gastrointestinal cancer atrates of 40 to 100 times those of the general population, in additionto osteoporosis, and a two-fold increase in the risk of fractures,including first-time hip fractures. Moreover, an unusually highpercentage of people with celiac disease suffer from the followingconditions: Anemia, Arthritis, Ataxia, Cancer—Non-Hodgkin’s Lymphoma, Cow's Milk Intolerance, Dermatitis, Diabetes-Type 1, Irritable Bowel Syndrome, Liver Disease, Migraine Headaches, Nerve Diseaseand/or Peripheral Neuropathy, Obesity, Osteoporosis,Osteomalacia/Low Bone Density, Pancreatic & Thyroid Disorders.
    According to a new study by doctors based in Sweden, people with celiac disease face a significantly higher risk of developing thyroid disorders, including hypothyroidism, hyperthyroidism and thyroiditis.
    The thyroid is a small, butterfly-shaped gland in the neck that creates the hormones that control human metabolism.  People with under-active thyroid, called hypothyroidism, suffer symptoms such as fatigue, sensitivity to cold, dry skin and weight gain, while people with overactive thyroid, called hyperthyroidism, commonly suffer from symptoms such as excessive sweating, heat intolerance, and nervousness. However, mild cases of hypo- or hyperthyroidism commonly present no symptoms at all. Inflammation of the thyroid gland is called Thyroiditis.
    The research team, led by Dr. Peter Elfstrom at Orebro University Hospital, reviewed Swedish national health records covering the period from 1963 to 2003. The team compared rates of thyroid disease for 14,000 people with celiac disease against some 68,000 non-celiac control subjects matched for age and gender.
    The results showed that people with celiac disease are diagnosed with hypothyroidism more than four times as often as non-celiacs, with hyperthyroidism more than three times as often as non-celiacs, and with hyperthyroidism more than 3.6 times as often as non-celiacs. Moreover, the relationship works both ways: people with established hypothyroidism, hyperthyroidism and thyroiditis face much higher rates of celiac disease.
    These results held true even after the data were adjusted for potential confounders, including the presence of diabetes mellitus. The researchers theorize that the association between celiac disease and thyroid disease may be due to shared genetic or immunological traits.
    This is just the latest in a string of studies that drives home the importance of early testing for suspected celiac cases, as early discovery and treatment with a gluten free diet greatly reduces associated complications in celiac disease.

    Celiac.com 03/01/2010 - Common autoimmune disorders often coexist in the same subjects, and to cluster in families. A research team recently set out to quantify the risk of diagnosis of coexisting autoimmune diseases in more than 3000 index cases with clinically proven Graves' disease or Hashimoto's thyroiditis.
    The research team included Kristien Boelaert, PhD, Paul R. Newbya, Matthew J. Simmonds, PhD, Roger L. Holder, Jacqueline D. Carr-Smith, Joanne M. Heward, PhD, Nilusha Manjia, Amit Allahabadia, MD, Mary Armitage, DM, Krishna V. Chatterjee, PhD, John H. Lazarus, MD, Simon H. Pearce, PhD, Bijay Vaidya, PhD, Stephen C. Gough, PhD, and Jayne A. Franklyn, PhD.
    To establish the prevalence of coexisting autoimmune disorders, the team conducted a cross-sectional multi-center study of 3286 Caucasian subjects from UK hospital thyroid clinics. 2791 of those had Graves' disease, 495 had Hashimoto's thyroiditis.
    The team used a comprehensive questionnaire to obtain complete personal and parental history for each subject, including information on common autoimmune disorders, and parental history of hyperthyroidism or hypothyroidism.
    The frequency of other autoimmune disorders was 9.67% for patients with Graves' disease and 14.3% for those with Hashimoto's thyroiditis index cases (P=.005).
    Rheumatoid arthritis was the most common coexisting autoimmune disorder, striking 3.15% of patients with Graves' disease, and 4.24% of Hashimoto's thyroiditis cases.
    However, both conditions carried substantially higher relative risks for nearly all other autoimmune diseases (>10 for pernicious anemia, systemic lupus erythematosus, Addison's disease, celiac disease, and vitiligo).
    Cases of Graves' disease showed relative “clustering” among index subjects with parental hyperthyroidism, while cases of Hashimoto's thyroiditis showed relative “clustering” among index subjects with parental hypothyroidism.
    Relative risks for most other coexisting autoimmune disorders were markedly increased among parents of index cases.
    This study is one of the largest so far to quantify the risk of diagnosis of coexisting autoimmune diseases among more than 3000 index cases with clinically proven Graves' disease or Hashimoto's thyroiditis.
    These results emphasize the the importance of screening for other autoimmune diagnoses when patients with autoimmune thyroid disease show new or nonspecific symptoms.

    Celiac.com 02/02/2012 - A team of researchers recently conducted a prospective controlled study on a gluten-free diet and autoimmune thyroiditis in patients with celiac disease.
    The research team included S. Metso, H. Hyytiä-Ilmonen, K. Kaukinen, H. Huhtala, P. Jaatinen, J. Salmi, J. Taurio, and P. Collin. They are affiliated with the Department of Internal Medicine at Tampere University Hospital in Tampere, Finland.
    Prior to the study, there had been contradictory data regarding the ways in which early diagnosis and a gluten-free diet might slow the progression of associated autoimmune diseases in celiac disease.
    The research team investigated the course of autoimmune thyroid diseases in newly diagnosed celiac disease patients, both before and after gluten-free dietary treatment.
    For their study, the team examined twenty-seven adults with newly diagnosed celiac disease, both at the time of diagnosis and after one year on gluten-free diet.
    They also recorded and examined previously diagnosed and subclinical autoimmune thyroid diseases. The team used ultrasound to measure thyroid gland volume and echo-genicity. They also measured autoantibodies against celiac disease and thyroiditis, and conducted thyroid function tests.
    As a control group, they enrolled twenty-seven non-celiac subjects, all of whom followed a normal, gluten-containing diet.
    The data showed that, upon diagnosis, ten of 27 celiac disease patients had either manifest (n = 7) or subclinical (n = 3) thyroid diseases. Only three of 27 control subjects (10/27 vs. 3/27, p = 0.055) had thyroid disease.
    After treatment with a gluten-free diet, thyroid volume continued to decrease significantly in the patients with celiac disease compared with the control subjects, indicating the progression of thyroid gland atrophy regardless of the gluten-free diet.
    Overall, celiac patients faced a higher risk of thyroid autoimmune disorders than non-celiac control subjects. Moreover, a gluten-free diet did not seem to stop or reverse the progression of autoimmune disease after one year.

    Celiac.com 04/21/2018 - Dear Friends and Readers,
    I have been writing articles for Scott Adams since the 2002 Summer Issue of the Scott-Free Press. The Scott-Free Press evolved into the Journal of Gluten Sensitivity. I felt honored when Scott asked me ten years ago to contribute to his quarterly journal and it's been a privilege to write articles for his publication ever since.
    Due to personal health reasons and restrictions, I find that I need to retire. My husband and I can no longer travel the country speaking at conferences and to support groups (which we dearly loved to do) nor can I commit to writing more books, articles, or menus. Consequently, I will no longer be contributing articles to the Journal of Gluten Sensitivity. 
    My following books will still be available at Amazon.com:
    Gluten-free Cooking for Dummies Student's Vegetarian Cookbook for Dummies Wheat-free Gluten-free Dessert Cookbook Wheat-free Gluten-free Reduced Calorie Cookbook Wheat-free Gluten-free Cookbook for Kids and Busy Adults (revised version) My first book was published in 1996. My journey since then has been incredible. I have met so many in the celiac community and I feel blessed to be able to call you friends. Many of you have told me that I helped to change your life – let me assure you that your kind words, your phone calls, your thoughtful notes, and your feedback throughout the years have had a vital impact on my life, too. Thank you for all of your support through these years.

    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
