    WHAT'S THE CELIAC RISK FOR CLOSE RELATIVES OF PEOPLE WITH THE DISEASE?


    Jefferson Adams

    Celiac.com 11/18/2015 - Researchers have known for some time that first-degree relatives (FDRs) of celiac patients are at high risk for developing the disease, and that prevalence among them varies from 1.6 to 38%. However, not much is known about specific risk levels when the FDR is sister, brother, mother, father, son, or daughter of a celiac patient.

    Photo: CC- Wendell OaskayA team of researchers recently conducted a meta-analysis and calculated pooled prevalence of celiac disease among FDRs, second-degree relatives (SDRs), and specific relations with given celiac patients. The research team included P. Singh, S. Arora, S. Lal, T.A. Strand, G.K. Makharia. They are variously affiliated with the Department of Medicine, Massachusetts General Hospital, Boston, Massachusetts, USA; Department of Medicine, Brigham and Women's Hospital, Boston, Massachusetts, USA; Max Healthcare, Gurgaon, India; Medical Services Division, Innlandet Hospital Trust, Lillehammer, Norway; and the Department of Gastroenterology and Human Nutrition at the All India Institute of Medical Sciences, New Delhi, India.

    The team searched 2,259 related medical articles, and found 54 articles relevant for their meta-analysis. They defined celiac disease diagnosis using standard biopsy and Marsh criteria. Analysis of their data group showed an overall celiac disease prevalence of 7.5% (95% confidence interval (CI) 6.3%, 8.8%) in 10,252 FDRs and 2.3% (95% CI 1.3%, 3.8%) in 642 SDRs.

    Pooled celiac disease rates were highest in siblings, at 8.9%, followed by offspring, at 7.9%, and parents, at 3.0%.

    A total of 8.4% of female FDRs showed rates of celiac disease compared to 5.2% male FDRs (P=0.047).

    Sisters and daughters of a primary patient had the highest risk of having celiac disease, at 1 in 7 and 1 in 8, respectively), compared to a risk of 1 in 13 in sons, 1 in 16 in brothers, 1 in 32 in mothers, and 1 in 33 in fathers.

    The data also revealed differences in the pooled prevalence of celiac disease in FDRs according to their geographic location.

    Average pooled rates of celiac disease among FDRs is 7.5%, but the actual rate for a given individual varies widely based on their relationship with the primary celiac patient, and is also influenced by gender and geographical location.

    Celiac.com 07/31/2003 - The findings of this new study are very significant for families of those with celiac disease. The results indicate that 17% of those related to two celiac disease-diagnosed siblings will also have the disease. Past studies have shown that around 10% of first-degree relatives of celiacs also have it, but this study is unique as it focuses on the increased risk for families where two siblings have the disease. This study further emphasizes the conclusions of past studies: If you have a relative with celiac disease--get tested, especially if it is a first-degree relative. - Scott Adams

    Abstract
    :
    "Prevalence of celiac disease among relatives of sib pairs with celiac disease in U.S. families
    Am J Gastroenterol. 2003 Feb;98(2):377-81
    Book L, Zone JJ, Neuhausen SL.
    Division of Pediatric Gastroenterology and Nutrition, Department of PediatricsUniversity of Utah, Salt Lake City, USA.
    OBJECTIVE: Celiac disease is a familial malabsorptive disorder with an estimated prevalence in first-degree relatives of 10-12%. The prevalence for first-degree and more distant relatives has not been determined in families where there are two affected first-degree relatives. The aim of our investigation was to estimate the prevalence and relative risk for celiac disease in relatives of two siblings diagnosed with celiac disease.
    METHODS: We ascertained sib pairs with celiac disease, and then identified all living first-degree relatives and available second-degree relatives to minimize ascertainment bias. We measured IgA endomysial antibodies, a highly specific and sensitive assay for celiac disease, in all subjects without a confirmed biopsy diagnosis. For those individuals with positive serologic tests, IgA tissue transglutaminase antibody tests and human leukocyte antigen DQA1 and DQB1 genotyping were performed for additional confirmation. Individuals with positive biopsy and/or serology were considered affected. We calculated the relative risk of being affected with celiac disease using the lambda® statistic.
    RESULTS: The prevalence of celiac disease in relatives of affected sib pairs was as follows: 21.3% (13/61) of siblings (lambda(S) = 53); 14.7% (10/68) of offspring (lambda(O) = 37); 17.2% (28/163) of first-degree relatives; 19.5% (16/82) of second-degree relatives; and 17.8% (52/292) of all relatives (lambda® = 44.5).
    CONCLUSIONS: In these families, we identified a sibling risk approximately double that found in previous reports, as well as significant risk for more distant relatives, probably because of sharing of a common gene. In families where at least two siblings have been diagnosed with celiac disease, relatives are at high risk for celiac disease. Screening should be considered for all family members.

    Effectiveness of the sorbitol H2 breath test in detecting histological damage among relatives of coeliacs.
    Tursi A, Brandimarte G, Giorgetti GM, Inchingolo celiac disease.
    Dept. of Emergency, L. Bonomo Hospital, Andria (BA), Italy.
    Celiac.com 08/07/2003 - An Italian study conducted by Dr. L. Bonomo and colleagues and published in the July 2003 edition of Scandinavian Journal of Gastroenterology concludes that A significant proportion of coeliacs may be missed if relatives are screened by serology only, while the efficacy of sorbitol H2-BT in screening relatives is confirmed. This study confirms that neither a breath test nor serology can replace intestinal biopsy, which remains the gold standard for the diagnosis of celiac disease, thus confirming the continued importance of performing biopsies for diagnosing celiac disease. The studys goal was to determine the diagnostic capabilities of serological tests (antigliadin (AGA), antiendomysium (EMA) and anti-tissue transglutaminase (anti-tTG)) and sorbitol H2 breath test (H2-BT) in the detection of celiac disease in first-degree relatives. The study screened 111 first-degree relatives of 37 celiac families using both test methods to determine candidates for small-bowel biopsy. First-degree relatives with abnormal test results underwent a small-bowel biopsy, as did those with negative serological and H2 breath test results who had clinical complaints or suspected that they may have celiac disease.
    The biopsy results were expressed using the Marsh classification system, and celiac disease was diagnosed in 49 of the 111 screened relatives of celiacs, or in 44.14%. A breakdown of the results is as follows: 5 showed Marsh IIIc, 8 Marsh IIIb, 16 Marsh IIIa, 13 Marsh II and 7 Marsh I lesions. 19 relatives showed the classical form of celiac disease, 20 showed the sub-clinical form, and 10 showed the silent form. The serological test results indicated an overall positivity of only 36.73%, with strong positive results only in those with severe intestinal damage and Marsh IIIb-c lesions. The sorbitol H2-BT breath test results showed an overall positivity of 83.67%, and showed strong positivity in patients with slight histological damage (Marsh I-IIIa).

    Celiac.com 02/20/2013 - Scientific evidence indicates that the risk of developing celiac disease cannot be explained solely by genetic factors. There is some evidence to support the idea that the season in which a child is born can influence the risk for developing celiac disease. It is known that babies born in summer months are likely to be weaned and introduced to gluten during winter, when viral infections are more frequent.
    A number of studies indicate that early viral infections can increase risk levels for celiac disease, however, earlier studies on birth season and celiac disease have been small, and their results have been contradictory.
    To better answer the question, a research team recently set out to conduct a more thorough study of the relationship between birth month and celiac disease.
    The research team included B. Lebwohl, P.H. Green, J.A. Murray, and J.F. Ludvigsson. The study was conducted through the Department of Paediatrics at Örebro University Hospital in Örebro, Sweden.
    To conduct the study, the team used biopsy reports from all 28 Swedish pathology departments to identify individuals with celiac disease, which they defined as small intestinal villous atrophy (n=29 096).
    Using the government agency Statistics Sweden the team identified 144,522 control subjects, who they matched for gender, age, calendar year and county.
    The team then used conditional logistic regression to examined the association between summer birth (March-August) and later celiac disease diagnosis (outcome measure).
    They found that 54.10% of people with celiac disease were born in the summer months compared with 52.75% of control subjects.
    So, being born in the summer is associated with a slightly higher risk of later celiac disease (OR 1.06; 95% CI 1.03 to 1.08; p).
    While summer birth was not associated with a higher rates of celiac diagnosis in later childhood (age 2-18 years: OR 1.02; 95% CI 0.97 to 1.08), it did show a slightly higher risk of developing celiac disease in adulthood (age ≥18 years: OR 1.04; 95% CI 1.01 to 1.07).
    In this study, the data show that people born during the summer months had a slightly higher risk of developing celiac disease, but that excess risk was small, and general infectious disease exposure early in life were not likely to increase that risk.

    Celiac.com 07/27/2015 - First-degree relatives of individuals with celiac disease are at increased risk for this disorder, but little is known about their risk for other autoimmune diseases.
    A research team recently set out to assess the risk of non-celiac autoimmune disease in first-degree relatives and spouses of people with celiac disease.
    The research team included Louise Emilsson, Cisca Wijmenga, Joseph A. Murray, and Jonas F. Ludvigsson. They are variously affiliated with the Primary Care Research Unit, Vårdcentralen Värmlands Nysäter, Värmland County, Sweden, the Department of Health Management and Health Economy, Institute of Health and Society, University of Oslo, Oslo, Norway, the Department of Genetics, University Medical Center Groningen, University of Groningen, Groningen, The Netherlands, the Division of Gastroenterology and Hepatology, Department of Internal Medicine, Mayo Clinic, Rochester, Minnesota, the Department of Medical Epidemiology and Biostatistics, Karolinska Institutet, Stockholm, Sweden, and with the Department of Pediatrics, Örebro University Hospital, Örebro, Sweden.
    The team found individuals with celiac disease by searching computerized duodenal and jejunal biopsies, collected from 1969 through 2008, at 28 pathology departments in Sweden.
    The team found 29,096 patients with celiac disease based on biopsy reports of villous atrophy of Marsh grade 3 or higher and matched individuals with celiac disease with up to 5 of 144,522 non-celiac control patients based on sex, age, county, and calendar year.
    Through Swedish health care registries, the team identified all first-degree relatives (fathers, mothers, siblings, and offspring) and spouses of 84,648 individuals with celiac disease, and 430,942 control subjects. The team used Cox regression analysis to calculate hazard ratios (HRs) for non-celiac autoimmune disease, such as Crohn’s disease, type 1 diabetes mellitus, hypothyroidism, hyperthyroidism, psoriasis, rheumatoid arthritis, sarcoidosis, systemic lupus erythematosus, or ulcerative colitis, within these groups.
    Cox analysis showed that during the follow-up period averaging just under 11 years, nearly 3333, or 4%, of the first-degree relatives of patients with celiac disease, and 12,860 relatives of controls (3.0%), had an autoimmune disease other than celiac disease.
    First-degree relatives of people with celiac disease had an increased risk of non-celiac autoimmune disease, compared with controls (HR, 1.28; 95% confidence interval, 1.23–1.33), as did spouses (HR, 1.20; 95% confidence interval, 1.06–1.35).
    Risk estimates for non-celiac autoimmune disease did not differ between first-degree relatives and spouses of individuals with celiac disease (interaction test: P = .11). Hazard Ratios for non-celiac autoimmune disease were highest in the first 2 years of follow-up evaluation.
    First-degree relatives and spouses of individuals with celiac disease have a significantly higher risk of non-celiac autoimmune disease.
    In addition to genetic factors, environmental factors and better awareness, testing and diagnosis might influence rates of autoimmune disorders in first-degree relatives of individuals with celiac disease.

    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:
