    SOME IBD PATIENTS ALSO SUFFER FROM NON-CELIAC GLUTEN SENSITIVITY


    Jefferson Adams

    Celiac.com 06/04/2015 - Some researchers feel that people who self report non-celiac gluten sensitivity (SR-NCGS) and also follow a gluten-free diet might actually fall within the spectrum of irritable bowel (IBS). Interestingly, recent reports suggest that large numbers of people with inflammatory bowel disease (IBD) also follow a gluten-free diet.

    Photo: CC--Robert HuffstutterA research team recently assessed the relationship between IBD and self-reported non-celiac gluten sensitivity (SR-NCGS). The team included I.Aziz, F. Branchi, K. Pearson, J. Priest, and D.S. Sanders. They are variously affiliated with the Department of Gastroenterology, Royal Hallamshire Hospital, Sheffield Teaching Hospitals, Sheffield, United Kingdom; and the Gastroenterology and Endoscopy Unit in the Department of Pathophysiology and Transplantation at the Fondazione IRCCS Cà Granda Ospedale Maggiore Policlinico, Department of Pathophysiology and Transplant, Università degli Studi di Milano in Milan, Italy.

    To screen for SR-NCGS and the use of a GFD, they used a cross-sectional questionnaire in 4 groups: ulcerative colitis (n = 75), Crohn's disease (n = 70), IBS (n = 59), and dyspeptic controls (n = 109). They also looked at diagnostic outcomes for IBD in 200 patients presenting with SR-NCGS.

    A total of 25 out of 59 patients with IBS (42.4%), and 40 out of 145 patients (27.6%) with IBD reported SR-NCGS. That number was just 19 of 109 for dyspeptic control subjects (17.4%). As far a gluten-free diet, currently, 11.9% of patients with IBS, and 6.2% of those with IBD are following a gluten-free diet, as compared with just 0.9% for dyspeptic controls; P = 0.02.

    For the purposes of of this study, the team made no differences between ulcerative colitis and Crohn's disease. However, 40.9% of Crohn's disease patients with SR-NCGS suffered from stricturing disease, compared with 18.9% for Chrohn's patients without SR-NCGS; (P = 0.046). Crohn's disease patients with SR-NCGS showed higher overall scores on the Crohn's Disease Activity Index (228.1 versus 133.3, P = 0.002) than those without SR-NCGS.

    The team analyzed 200 cases presenting with SR-NCGS, and found that 197 of them, or 98.5% were most likely diet-related IBS. However, 3 of the SR-NCGS patients (1.5%) actually had IBD, with all of the associated alarm symptoms, and/or abnormal blood parameters.

    The results show that SR-NCGS is not exclusive to IBS, but is also seen in some patients with IBD, which is a more severe, more debilitating condition.

    The team is calling for randomized studies to further delineate the nature of this relationship and clarify whether a gluten-free is appropriate for certain IBD patients.

    Celiac.com 06/13/2012 - In general, doctors and researchers know a good deal about how celiac disease works, and they are finding out more all the time. However, they know very little about non-celiac gluten sensitivity (NCGS).
    In an effort to learn more about non-celiac gluten sensitivity, a team of researchers recently carried out a study to measure the presence of somatization, personality traits, anxiety, depression, and health-related quality of life in NCGS individuals, and to compare the results with celiac disease patients and healthy control subjects. They also compared the response to gluten challenge between patients with non-celiac gluten sensitivity and those with celiac disease.
    The research team included M. Brottveit, P.O. Vandvik, S. Wojniusz, A. Løvik, K.E. Lundin, and B. Boye, of the Department of Gastroenterology at Oslo University Hospital, Ullevål in Oslo, Norway.
    In all, the team looked at 22 patients with celiac disease and 31 HLA-DQ2+ NCGS patients without celiac disease. All patients were following a gluten-free diet.
    Over a three day period, the team challenged 17 of the celiac disease patients with orally ingested gluten. They then recorded the symptoms reported by those patients. They did the same with a group of 40 healthy control subjects.
    The team then had both patients and healthy control subjects complete questionnaires regarding anxiety, depression, neuroticism and lie, hostility and aggression, alexithymia and health locus of control, physical complaints, and health-related quality of life.
    Interestingly, patients with non-celiac gluten sensitivity reported more abdominal (p = 0.01) and non-abdominal (p < 0.01) symptoms after the gluten challenge than patients with celiac disease. The increase in symptoms in non-celiac gluten sensitivity patients was not related to personality.
    However, the two groups both reported similar responses regarding personality traits, level of somatization, quality of life, anxiety, and depressive symptoms. Responses for both groups were about the same as for healthy controls.
    The results showed that patients with non-celiac gluten sensitivity did not show any tendencies toward general somatization, as both celiac disease patients and those with non-celiac gluten sensitivity showed low somatization levels.

    Celiac.com 09/23/2013 - Patients with non-celiac gluten sensitivity (NCGS) do not have celiac disease, but see an improvement in symptoms when they adopt gluten-free diets.
    A team of researchers recently investigated the specific effects of gluten after dietary reduction of fermentable, poorly absorbed, short-chain carbohydrates (fermentable, oligo-, di-, monosaccharides, and polyols [FODMAPs]) in patients with suspected NCGS.
    The research team included Jessica R. Biesiekierski, Simone L. Peters, Evan D. Newnham, Ourania Rosella, Jane G. Muir, and Peter R. Gibson.
    The team performed a double-blind cross-over trial of 37 subjects (aged 24−61 y, 6 men) with NCGS and irritable bowel syndrome (based on Rome III criteria), but not celiac disease.
    They assigned study participants randomly to groups given a 2-week diet of reduced FODMAPs, and were then placed on high-gluten (16 g gluten/d), low-gluten (2 g gluten/d and 14 g whey protein/d), or control (16 g whey protein/d) diets for 1 week, followed by a washout period of at least 2 weeks.
    The researchers then evaluated serum and fecal markers of intestinal inflammation/injury and immune activation, and indices of fatigue.
    The team then crossed twenty-two participants over to groups receiving gluten (16 g/d), whey (16 g/d), or control (no additional protein) diets for 3 days, using visual analogue scales to evaluate symptoms.
    They found that gastrointestinal symptoms consistently and significantly improved for all patients during reduced FODMAP intake, but significantly worsened to a similar degree when their diets included gluten or whey protein.
    The team saw gluten-specific effects in just 8% of study subjects. They saw no diet-specific changes in any biomarker. During the 3-day re-challenge, participants’ symptoms increased by similar levels among groups. Gluten-specific gastrointestinal effects were not reproduced. An order effect was observed.
    A placebo-controlled, cross-over re-challenge study showed no evidence of specific or dose-dependent effects of gluten in patients with NCGS placed diets low in FODMAPs.

    Celiac.com 06/16/2014 - Differentiating between celiac disease and non-celiac gluten sensitivity (NCGS) is important for appropriate treatment, but is often challenging.
    A team of researchers recently set out to assess the best way to distinguish between celiac disease and non-gluten sensitivity. The research team included Toufic A Kabbani, Rohini R Vanga, Daniel A Leffler, Javier Villafuerte-Galvez, Kumar Pallav, Joshua Hansen, Rupa Mukherjee, Melinda Dennis and Ciaran P Kelly.
    For their study, the team reviewed records for 238 patients who were assessed for symptoms responsive to gluten restriction without having celiac disease ruled in or out. For each patient, clinicians noted the demographic information, presenting symptoms, serologic, genetic, and histologic data, nutrient deficiencies, personal history of autoimmune diseases, and family history of celiac disease.
    They define NCGS as symptoms responsive to a gluten-free diet, together with negative celiac blood tests and negative duodenal biopsies while on a gluten-containing diet, or negative human leukocyte antigen (HLA) DQ2/DQ8 testing. Of the 238 patients in the study, 101 had celiac disease, 125 had NCGS, 9 had non-celiac enteropathy, and 3 remained undetermined. Nearly 70% of celiac disease subjects suffered symptoms of malabsorption compared with just under 25% of the NCGS subjects (P<0.0001).
    In addition, the patients with celiac disease were far more likely to have a family history of celiac disease (P=0.004), personal history of autoimmune diseases (P=0.002), or nutrient deficiencies (P<0.0001).
    The positive likelihood ratio for celiac disease diagnosis of a >2× upper limit of normal IgA trans-glutaminase antibody (tTG) or IgA/IgG deaminated gliadan peptide antibody (DGP) with clinical response to a gluten-free diet was 130 (confidence interval (CI): 18.5–918.3).
    The positive likelihood ratio of the combination of gluten-responsive symptoms and negative IgA tTG or IgA/IgG DGP on a regular diet for NCGS was 9.6 (CI: 5.5–16.9).
    When individuals with negative IgA tTG or IgA/IgG DGP also lacked symptoms of malabsorption (weight loss, diarrhea, and nutrient deficiencies) and celiac disease risk factors (personal history of autoimmune diseases and family history of celiac disease), the positive likelihood ratio for NCGS increased to 80.9.
    Based on their findings, the team developed a diagnostic algorithm to distinguish celiac disease from NCGS.
    People with negative celiac blood tests (IgA tTG or IgA/IgG DGP, who are eating a regular gluten-containing diet, are unlikely to have celiac disease.
    Those with negative serology who show no clinical signs of malabsorption, and show no celiac disease risk factors, are highly likely to have NCGS and may not require further testing. Those with positive blood tests should undergo HLA typing to determine the need for biopsy.

    Celiac.com 03/23/2015 - There's been a bit of ping-ponging going on about the status of non-celiac gluten sensitivity as a valid medical condition. Studies have yielded conflicting results, with some supporting, and others negating, the existence of non-celiac gluten-sensitivity. 
    So what's the deal? Does non-celiac gluten sensitivity exist, or not? Researchers and clinicians continue to debate whether people without celiac disease or wheat allergy who consume gluten can experience intestinal and extra-intestinal symptoms attributable to non-celiac gluten sensitivity (NCGS).
    Taking the latest stab at the problem, a team of researchers recently conducted a randomized, double-blind, placebo-controlled, cross-over trial to determine the effects of administration of low doses of gluten to subjects with suspected NCGS. The research team included A. Di Sabatino, U. Volta, C. Salvatore, P. Biancheri, G. Caio, R. De Giorgio, M. Di Stefano, and G. R. Corazza. They are variously affiliated with the First Department of Internal Medicine at St Matteo Hospital Foundation at the University of Pavia in Pavia, Italy, and with the Department of Medical and Surgical Sciences at St Orsola-Malpighi Hospital at the University of Bologna in Bologna, Italy.
    For their study, the team enrolled 61 adults without celiac disease or wheat allergy, but who believe that eating gluten-containing food to be causing of their intestinal and extra-intestinal symptoms. The team randomly assigned participants to groups that received either 4.375 g/day gluten or rice starch (placebo) for 1 week, each via gastro-soluble capsules. Study subjects spend one week on a gluten-free diet, and then switched groups.
    The primary outcome was the change in overall (intestinal and extra-intestinal) symptoms, determined by established scoring systems, between gluten and placebo intake. A secondary outcome was the change in individual symptom scores between gluten vs placebo.
    Per-protocol analysis of data from the 59 patients who completed the trial shows that intake of gluten significantly increased overall symptoms compared with placebo (P=.034). Among the intestinal symptoms, abdominal bloating (P=.040) and pain (P=.047) were significantly more severe when subjects received gluten than placebo. Among the extra-intestinal symptoms, foggy mind (P=.019), depression (P=.020), and aphthous stomatitis (P=.025) were also worse when subjects received gluten than placebo.
    In this cross-over trial, subjects with suspected NCGS saw significantly more severe symptoms during 1 week of intake of small amounts of gluten, compared with placebo. So, at least for now, the NGCS ball seems to be back in the court that considers it a valid medical condition.

    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
    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:
