    CELIAC RATES FOUR TIMES HIGHER AMONG IRRITABLE BOWEL SYNDROME SUFFERERS


    Jefferson Adams

    Celiac.com 05/18/2009 - People with clinical irritable bowel syndrome (IBS) suffer from biopsy-proven celiac disease at rates that are more than four times higher than in non-IBS control subjects, according to the results of a recent systematic review and meta-analysis conducted by Alexander C. Ford, MBChB, MD, MRCP, from Health Sciences Centre, McMaster University, Hamilton, Ontario, Canada, and colleagues.

    Prior studies have indicated that people with IBS had higher rates of celiac disease, but evidence has not been clear, and medical guidelines do not always call for celiac screening in these individuals.

    To determine rates of celiac disease in random adults meeting clinical criteria for IBS, the research team reviewed MEDLINE from 1950 to May 31, 2008, and EMBASE from 1980 to May 31, 2008. They isolated case series and case-control studies that contained data for celiac disease blood screens. They found 14 such studies.

    From each study, they isolated and aggregated positive serologic test results for celiac disease and biopsy-proved celiac disease. They then compared the data to that for patients with IBS and control individuals, using an odds ratio (OR) and 95% confidence interval (CI).

    The team isolated 4204 suitable cases from the identified studies. Of those, 2278 met clinical criteria for IBS (54%). The overall rate of positive immunoglobulin A (IgA)–class antigliadin antibodies (AGA) was 4.0% (95% CI, 1.7% – 7.2%), the rate of positive endomysial antibodies (EMA) was 1.63% (95% CI, 0.7% – 3.0%), and the rate of tissue transglutaminase (tTGA) was 4.1% (95% CI, 1.9% – 7.0%). For biopsy-proven celiac disease, the overall rate was 4.1% (95% CI, 1.9% – 7.0%).

    In patients who met the clinical criteria for IBS compared with non-IBS control subjects, aggregate OR for positive IgA-class antigliadin antibodies was 3.40 (95% CI, 1.62 – 7.13), aggregate OR for either positive EMA or tTGA was 2.94 (95% CI, 1.36 – 6.35), and aggregate OR for biopsy-proved celiac disease was 4.34 (95% CI, 1.78 – 10.6).

    The study did have some weaknesses, including issues with the methodology governing study selection, possible spectrum bias in case-control studies, possible selection bias in studies based in secondary care, and, in some cases, results too limited to allow meaningful aggregation of data.

    Still the research team concludes that rates of biopsy-proven celiac disease are more than four times higher for IBS patients than for non-IBS controls. The team recommends that, if screening is undertaken, EMA or tTGA testing be used in lieu of IgA-AGA testing due to their higher positive predictive value, though they admitted that results will depend on celiac rates in the population being screened.  

    The study was supported by the American College of Gastroenterology.

    Celiac.com 06/15/2008 - Many people with celiac disease have stories to tell about the about how difficult it can be to get a getting a proper diagnosis. Celiac disease can mimic so many other conditions. Irritable Bowel Syndrome (IBS) is one of those conditions. The symptoms for Irritable Bowel Syndrome and for celiac disease are often similar as a result the diagnosis of celiac disease can be delayed or missed and misdiagnosed as irritable bowel syndrome.
    In an effort to reduce the misdiagnosis of celiac disease as Irritable Bowel Syndrome, Britain’s National Institute for Health and Clinical Excellence has drawn up new guidelines covering the diagnosis of Irritable Bowel Syndrome. The guidelines call for all diagnosis of Irritable Bowel Syndrome to be preceded by a screen for celiac disease. Keeping this in mind, anyone suffering from Irritable Bowel Syndrome, and who has not been tested for celiac disease, might want to take the initiative and check with their doctor to see if further testing might be in order.
    Studies show that a minimum of 1 out of every 100 people in Britain suffers from celiac disease, but that only 1 out of 8 is properly diagnosed. More worrisome still is the fact that new research shows that it takes an incredible 13 years on average before the diagnosis are made. That means 13 years of unnecessary pain and discomfort, to say nothing of potential systemic damage for those awaiting a proper diagnosis of celiac disease, including osteoporosis, bowel cancer and increased risk of other autoimmune diseases.
    Since similar numbers likely prevail in America, it's good to keep an eye on clinical changes like the one recently made in Britain. Again, for people diagnosed with IBS, but who have not been evaluated for celiac disease, it might be good to consider getting checked for celiac disease, even if these changes are not officially implemented in America anytime soon. Changes in diagnostic and treatment practices that benefit people with celiac disease are long overdue and highly welcomed by the celiac community.
    As our abilities to evaluate diagnostic and treatment practices continue to expand, look for important changes in the clinical approach to celiac disease, greater awareness among the general population, and improvements in the quality of life among celiacs.

    Celiac.com 10/10/2008 - A team of Finnish researchers announced that they have found high rates of undetected celiac disease in elderly populations. They have also noted that a significant number of those older people diagnosed with celiac disease showed only minor symptoms. The study team was made up of doctors A. Vilppula, P. Collin, M. M¨aki, R. Valve, M. Luostarinen, I. Krekel¨a, H. Patrikainen, K. Kaukinen, and L. Luostarinen.
    Even with a wealth of new information on celiac disease from numerous recent studies, along with better testing methods, we still don’t know very much about rates of celiac disease in older people.  Motivated by that fact, the team recently set out to study the prevalence of celiac disease in elderly populations.
    In theory, celiac disease should occur in the elderly at rates similar to, or lower than, those of the general population. Since current research indicates that about 1 person in a hundred has celiac disease, it seems logical to figure that rates of celiac disease among the elderly would be the same or even lower than rates for the general population.
    The researchers figured that clinically silent or undiagnosed celiac disease would be rare in elderly populations, as they would be likely to develop obvious symptoms. But the team was surprised to find that rates of celiac disease among the elderly are more than double those of the general population.
       
    They looked at 2,815 individuals between the ages of 52–74. They took blood samples from everyone and isolated people who showed signs of clinical celiac disease. They then screened the samples for IgA tissue transglutaminase antibodies. Subjects with positive antibody tests were given a small bowel biopsy. The doctors found celiac disease in 60 individuals, 25 (0.89%) through positive blood tests, and 35 (1.24%) through biopsy, for a total prevalence of in elderly subjects of 2.13% with 95% confidence intervals (1.60–2.67%). Of the screen-detected cases, only 15 had symptoms, and those were mostly mild. Driving home the dangers of late diagnosis, two out of the 60 had small bowel T-cell lymphoma and two had gastric cancer.
    Altogether, celiac disease was diagnosed through biopsy, and by blood test without a post-gluten-free diet follow-up test at a rate of 2.45% (1.88–3.02%).
    This study shows that celiac disease is far more prevalent in elderly people than in the general population.  To better detect and treat celiac disease in elderly populations, the doctors are encouraging the use of active case finding using blood tests, since undetected celiac disease can lead to serious complications and even early death.

    Celiac.com 03/13/2009 - A recent study confirms that celiac disease affects adults with Turner Syndrome at rates of up to 5%, compared to 1% for the general population.
    A team of researchers recently set out to assess rates of celiac disease in adults with Turner Syndrome. Led by doctor A. Frost of the Department of Endocrinology at University College Hospital in London, UK, the research team included doctors M. Band, G. Conway.
    The researchers enlisted 256 adults with clinically proven Turner Syndrome. Five turned out to have existing diagnosis of celiac disease. The team conducted IgA endomysium antibody (EMA) screening for celiac disease on the remaining 251 Turner Syndrome patients.  Eight patients (3.2%) showed positive EMA screens. Doctors offered those eight patients endoscopy with duodenal biopsy.
    Seven patients committed to duodenal biopsy, and all seven (2.8%) showed positive histological confirmation for celiac disease. Thus, the doctors reasonably estimate the rate of sub-clinical celiac disease to be between 2.8% and 3.2%. When the existing cases are factored in, the total population shows rates between 4.7% and 5.1%.
    The team conducted human leukocyte antigen (HLA) typing in the existing celiac disease cases and new EMA-positive cases. Ten of those 13 patients submitted to HLA typing. Eight showed positive results for HLA-DQ2, one for HLA-DQ8, while one showed negative results for both HLA-DQ2 and HLA-DQ8.
    The study demonstrates that celiac disease affects adults with Turner Syndrome at rates of up to 5 times those of the general population, and the results are consistent with previous data published in pediatric populations.

    Celiac.com 05/14/2012 - Should gluten sensitivity be thought of as “celiac light,” as just one of the milder manifestations within the wider spectrum of celiac disease? Some doctors and researchers think so.
    Over the past several years, there has been increasing discussion concerning gluten sensitivity as a possible cause of irritable bowel syndrome (IBS) symptoms in patients for whom celiac disease has been excluded. 
    This is undoubtedly because gluten sensitivity, like IBS, is a symptom-based condition of diverse pathogenesis. As discussed, some have argued that gluten sensitivity might be best thought of as “celiac light,” representing the milder domains of the celiac disease spectrum.
    However, there are some data to suggest that a subset of patients with gluten sensitivity may actually belong to the spectrum of celiac disease.
    In a recent letter to the editors of the American Journal of Gastroenterology, doctors Courtney C. Ferch and William D. Chey of the Division of Gastroenterology at the University of Michigan Health System in Ann Arbor, Michigan, comment at length on the latest findings regarding Irritable Bowel Syndrome and gluten sensitivity without celiac disease.
    Ferch and Chey note that gluten sensitivity is one of the most rapidly growing sectors in the food industry, with gluten-free products accounting for $1.31 billion in U.S. sales alone in 2011. Those sales are expected to exceed $1.6 billion by 2015.
    Major food manufacturers such as General Mills and Betty Crocker, along with popular restaurant chains like PF Chang's and Subway are busy introducing new gluten-free options, or retooling original products into gluten-free versions.
    People with gluten sensitivity typically show symptoms after eating gluten, but show no evidence of celiac disease or food allergy.
    Unlike celiac disease, there are no accepted biomarkers for gluten-sensitivity. Doctors diagnose the condition mainly by looking at the connection between eating gluten and the presence adverse symptoms.
    Numerous studies on gluten sensitivity suffer have included small sample size, a lack of adequate controls, a lack of blinding, and the use of non-validated outcome measures. Even with these limitations, Ferch and Chey say there are several studies worthy of further consideration.
    One of the studies discussed in the Ferch and Chey was a double-blind, placebo-controlled, dietary re-challenge trial performed by Biesiekierski et al. The study sought to better understand the role of gluten ingestion in the development of gastrointestinal (GI) and non-GI symptoms in patients diagnosed with IBS.
    The Biesiekierski study included a sample of 34 patients diagnosed with IBS by the Rome III criteria who had experienced symptom improvement with a gluten-free diet for 6 weeks before study enrollment. Celiac disease had been excluded in all study participants by either a negative HLADQ2/HLA-DQ8 haplotype or a normal duodenal biopsy. The study excluded patients with conditions such as cirrhosis, inflammatory bowel disease, non-steroidal anti-inflammatory drug ingestion, or excessive alcohol.
    Over a six week double-blind randomization phase, study participants followed either a gluten-free or gluten-containing diet that was assigned at random. Nineteen of the 34 patients ate food containing 16 g of gluten per day. The other 15 patients ate gluten-free bread and mufï¬ns. Gluten used in the study was free of fermentable oligo-, di-, monosaccharides and polyols, and its protein distribution included 2.3% nongluten, 45.7% glutenin, and 52% gliadin.
    The primary outcome of the study was the proportion of patients answering “no” on over half of the occasions at the end of each week to this question: “Over the past week, were your symptoms adequately controlled?”
    The study team also assessed secondary outcomes including bloating, abdominal pain, satisfaction with stool consistency, nausea, and tiredness using a 100-mm visual analog scale.
    Once the study period ended, the results showed that many more patients in the gluten group compared with the gluten-free group answered “no” to the primary outcome question (68% vs 40%; P .001).
    Compared with the gluten-ingesting group, those who remained gluten-free also reported signiï¬cant improvements in pain (P .016), bloating (P .031), satisfaction with stool consistency (P .024), and tiredness (P .001), although they showed similar levels of wind (P .053) or nausea (P .69).
    The results of celiac antibodies at baseline and after the dietary intervention were
    similar.  The team also found that diet had no effect on intestinal permeability as measured by urine lactuloseto-rhamnose ratio. Additionally, they found detectable fecal lactoferrin levels in just one patient during the treatment period.
    Meanwhile, high-sensitivity C-reactive protein levels remained normal before and after the dietary intervention.
    There was no difference in the level of symptoms experienced by those with and without HLA-DQ2 and HLA-DQ8 alleles. The authors felt that these data support the existence of non–celiac-associated gluten sensitivity. They concluded that gluten is in fact tied to overall IBS symptoms, bloating, dissatisfaction with stool consistency, abdominal pain, and fatigue in some patients.
    In their letter, Ferch and Chey also comment on several side issues.
    First, they note that a recent global meta-analyses of studies showed that patients with IBS symptoms had signiï¬cantly higher rates of celiac disease than controls. As such, they point out that the American College of Gastroenterology Task Force now recommends routine celiac blood screens for patients with diarrhea-predominant IBS and IBS with a mixed bowel pattern (grade 1B recommendation).
    Secondly, they note that there has been much recent discussion around the potential role of food in IBS symptoms that has focused on celiac disease. However, they point out that much has been made over the possible role of food, and possibly celiac disease, in IBS symptoms. However, they note that data from US studies show no higher risk for celiac disease among patients with IBS symptoms and no warning signs.
    Although these results are certainly intriguing and hypothesis generating, they require validation in larger, randomized, controlled trials in other parts of the world.
    What is clear and important for providers to understand is that gluten sensitivity is here to stay and signiï¬cantly more likely for them to encounter in day-to-day practice than 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.

    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:
