    CAN SCIENCE TAKE THE GUESSWORK OUT OF DIAGNOSING SERONEGATIVE CELIAC DISEASE?


    Jefferson Adams


    • Can science improve current diagnosis of seronegative celiac disease?


    Celiac.com 09/27/2017 - Patients who have clinical, genetic and histological signs of celiac disease, but no serological markers, present a challenge when it comes to making a diagnosis. If the patient doesn't have elevated antibodies, what signs do doctors look for? What's the best way to evaluate the patient's natural history and response to a gluten-free diet?

    A team of researchers recently set out to outline a specific profile, and to evaluate the natural history and response to a gluten-free diet of patients with seronegative celiac disease.

    The research team included Maria Pina Dore; Giovanni Mario Pes; Ivana Dettori; Vincenzo Villanacci; Alessandra Manca and Giuseppe Realdi. They are variously affiliated with the Internal Medicine Section, Department of Clinical and Experimental Medicine, University of Sassari, Sassari, Italy, with the Baylor College of Medicine, Michael E. DeBakey VAMC, Houston, TX, USA, the Pathology Section, Department of Molecular and Translational Medicine, Spedali Civili and University of Brescia, Brescia, Italy, and with the Pathology Section, Department of Clinical and Experimental Medicine, University of Sassari in Sassari, Italy.

    Patients with duodenal mucosa damage Marsh I, II and III stages, HLA DQ2/DQ8 haplotype and clinical features suggestive of celiac disease, but with negative celiac serology, were defined as seronegative celiac patients.

    The team excluded other common causes of duodenal mucosa damage. They the compared HLA–DR and DQ genotype/haplotype between all Marsh stages of patients with seronegative and seropositive celiac disease. They then assessed clinical features, lab tests and histological findings after a gluten-free diet and a gluten re-challenge. The group provided the team with a long follow-up period to gather data.

    The researchers enrolled a total of 48 patients who fulfilled diagnostic criteria over a 4-year period. Patients with seronegative and seropositive celiac disease showed similar clinical phenotype and HLA−DR and DQ frequencies. However, Marsh I stage was seen in 42% of seronegative patients (42% vs 22%; p<0.05).

    After a 1-year gluten-free diet trial, clinical symptoms, histological features and laboratory testing improved in 40 patients and worsened in those who underwent a 6-months gluten challenge. Five patients with seronegative celiac disease (25%) experienced the occurrence of autoimmune diseases during an average follow-up of about 11 years.

    Patients with seronegative celiac disease did not show any specific profile, but they did see benefits from a gluten-free diet similar to seropositive patients.

    In the absence of more sensitive serological markers, diagnosing seronegative celiac disease remains an often confusing and challenging process of excluding various other possibilities.

    Celiac.com 06/05/2017 - Doctors diagnose celiac disease by confirming various clinical, genetic, serologic, and duodenal morphology features. Based on retrospective data, recent pediatric guidelines propose eliminating biopsy for patients with IgA-TTG levels more than 10-times the upper limit of normal (ULN), along with a few other criteria.
    One retrospective study showed that researchers using levels of IgA-TTG and total IgA, or IgA-TTG and IgG against deamidated gliadin (IgG-DGL) could identify patients both with and without celiac disease. A team of researchers recently set out to validate the positive and negative predictive values (PPV and NPV) of these diagnostic procedures.
    The research team included Johannes Wolf, David Petroff, Thomas Richter, Marcus KH. Auth, Holm H. Uhlig, Martin W. Laass, Peter Lauenstein, Andreas Krahl, Norman Händel, Jan de Laffolie, Almuthe C. Hauer, Thomas Kehler, Gunter Flemming, Frank Schmidt, Astor Rodriques, Dirk Hasenclever, and Thomas Mothes.
    Their team conducted a prospective study of 898 children undergoing duodenal biopsy analysis to confirm or rule out celiac disease at 13 centers in Europe. They then compared results from antibody tests with results from biopsies, follow-up data, and diagnoses made by the pediatric gastroenterologists. In all cases, diagnosis was made for celiac disease, no celiac disease, or no final diagnosis.
    Blinded researchers measured levels of IgA-TTG, IgG-DGL, and endomysium antibodies, while tissue sections were analyzed by local and blinded reference pathologists. The team validated two procedures for diagnosis: total-IgA and IgA-TTG, as well as IgG-DGL with IgA-TTG. Patients whose antibody concentrations for all tests were below 1-fold the ULN were assigned to the no celiac disease category.
    Those whose antibody concentrations for at least one test were above 10-fold the ULN were assigned to the celiac disease category. All other cases were considered to require biopsy analysis.
    The team calculated the ULN values using the cut-off levels suggested by the test kit manufacturers. They conducted HLA-typing for 449 participants. To extrapolate the PPV and NPV to populations with lower rates of celiac disease, they used models that accounted for how specificity values change with prevalence.
    In all, the team found 592 patients with celiac disease, 345 who did not have celiac disease, and 24 with no final diagnosis.
    The TTG-IgA procedure identified celiac disease patients with a PPV of 0.988 and an NPV of 0.934. The TTG-DGL procedure identified celiac disease patients with a PPV of 0.988 and an NPV of 0.958.
    Their extrapolation model estimated that PPV and NPV would remain above 0.95 even at a disease prevalence as low as 4%. Meanwhile, tests for endomysium antibodies and HLA type did not increase the PPV of samples with levels of IgA-TTG 10-fold or more above the ULN.
    Interestingly, the pathologists disagreed in their analyses of duodenal morphology about 4.2% of the time, a rate comparable to the error rate for serologic tests.
    This study validates the use of the TTG-IgA procedure and the TTG-DGL procedure in lieu of biopsy to diagnose pediatric patients with or without celiac disease.

    Celiac.com 07/13/2017 - Until recently, duodenal biopsy was considered the gold standard for diagnosing celiac disease, but that is changing.
    A number of studies have shown that celiac disease can be diagnosed using serological tests alone, but many clinicians have yet to embrace this approach.
    In both retrospective and prospective studies, one research team showed that certain IgA-tissue transglutaminase antibodies levels can predict celiac disease in adults 100% of the time.
    After making some adjustments to the analytical method for measuring the antibody, a team of researchers recently set out to to determine whether such serum tests can reliably diagnose celiac disease in large numbers adult patients without the need for small bowel biopsy.
    The research team included GKT Holmes, JM Forsyth, S Knowles, H Seddon, PG Hill, and AS Austin.
    They are variously associated with the Royal Derby Hospital, the Department of Pathology, and the Derby Digestive Diseases Centre at the Royal Derby Hospital in Derby, UK.
    For their study, the team conducted a retrospective analysis in an unselected series of 270 adult patients who underwent small bowel biopsies and the measurement of serum IgA-tissue transglutaminase antibody levels from 2009 to 2014.
    At an IgA-tissue transglutaminase antibody cut-off greater than 45 U/ml (>8×upper limit of normal+2SDs) the positive predictive value for celiac disease in this cohort was 100%; 40% of cases were above this cut-off.
    The team found that they could use IgA-tissue transglutaminase antibody levels to reliably diagnose celiac disease in a high proportion of these adult patients.
    This study adds to the growing body of evidence that supports the diagnosis of celiac disease without a mandatory small bowel biopsy.
    As a realist of these findings, the study team has changed the diagnostic guidelines for their center, and will now make celiac diagnosis based on cut-off levels of IgA-tissue transglutaminase.
    This is exciting news. For many, many years, the biopsy was considered the gold standard for diagnosing celiac disease.
    By eliminating biopsies in favor of IgA-tissue transglutaminase levels, diagnosing celiac disease could become much easier and even cheaper.

    Celiac.com 09/11/2017 - The FDA has granted clearance for Immco Diagnostics' ELISA for celiac disease, and for Roche's Benchtop Analyzer. What does that mean?
    Immco's test is conducted as a solid phase immunoassay and is intended for the qualitative or semiquantitative detection of IgA or IgG antigliadin antibodies in human blood, and thus to aid in diagnosing patients with celiac disease or dermatitis herpetiformis in conjunction with other laboratory and clinical findings.
    In other important diagnostic news, a benchtop analyzer from Roche Diagnostics and an immunoassay system from Shenzhen New Industries Biomedical was among the instruments and tests cleared by the US Food and Drug Administration in July, according to the agency. The FDA granted 510(k) clearance to Roche's Cobas b 101 instrument platform, as well as the Cobas HbA1c test. The fully automated and self-contained Cobas b 101 uses a single-use reagent disc to measure HbA1c from capillary and/or venous whole-blood samples, according to a document filed with the FDA.
    The Cobas HbA1c is an in vitro diagnostic test for detecting the presence of glycate hemoglobin, which develops when hemoglobin joins with glucose in the blood, becoming 'glycated'. By measuring glycated hemoglobin (HbA1c), clinicians are able to get an overall picture of what our average blood sugar levels have been over a period of weeks/months.
    For people with diabetes this is important as the higher the HbA1c, the greater the risk of developing diabetes-related complications. The HbA1c assay is designed for use with the Cobas b 101 platform, which is not a portable home test, but is intended for a clinical laboratory or point-of-care setting.
    Other instruments receiving FDA clearance in July include a new flow cytometer from Becton Dickinson; an expanded version of Bruker's MALDI Biotyper; and expanded indications for BioMérieux's Vitek MS MALDI-TOF Mass Spectrometery System. The FDA recently cleared the Maglumi 2000 automated immunoassay analyzer from Shenzhen New Industries Biomedical, which uses chemiluminescent technology for running IVD tests on clinical serum samples. The firm's Maglumi 2000 TSH assay for the quantitative determination of thyroid-stimulating hormone in human serum also received 510(k) clearance. The assay is for diagnosing thyroid disorders.
    These are just a few of many new tests and analysis devices that are changing the way doctors diagnose and manage celiac disease, diabetes, and other diseases.
    Look for tests like this to have a profound influence on the way diseases are diagnosed and managed in the future.

    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.
