    Rates of celiac disease vary by region, with a sharp variation between Americans living in the northern United States and Americans living in the southern part of the country. A team of researchers recently examined geographic, demographic, and clinical factors associated with prevalence of celiac disease and gluten-free diet in the United States.

    The research team included Aynur Unalp-Arida, M.D., Ph.D, of the National Institute of Diabetes and Digestive and Kidney Diseases, National Institutes of Health, Department of Health and Human Services, Constance E. Ruhl, M.D., Ph.D., of Social & Scientific Systems, Inc., Silver Spring, MD, and Rok Seon Choung, M.D., Ph.D., Tricia L. Brantner, and Joseph A. Murray, M.D., of the Division of Gastroenterology and Hepatology, Mayo Clinic, Rochester, MN.

    For their population-based study, their team analyzed data on gluten-related conditions from the US National Health and Nutrition Examination Survey, from 2009 through 2014, on 22,277 participants 6 years and older. The team found celiac patients using results of serum tests for immunoglobulin A against tissue transglutaminase and endomysium, or of both, a health clinical diagnosis, and adherence to a gluten-free diet.

    The team also accounted for patients who follow a gluten-free diet without a diagnosis of celiac disease. Using the patients' status of gluten-related conditions, the team then compared average serum levels of biochemical and nutritional markers.

    Their results showed that 0.7% of participants had celiac disease, while 1.1% of participants avoid gluten without celiac disease. People who lived at latitudes of 35–39º North or at latitudes of 40º North were more likely to have celiac disease than individuals who lived at latitudes below 35º North, regardless of race or ethnicity, socioeconomic status, or body mass index. People who lived at 40º North or higher were more likely to avoid gluten without a celiac diagnosis, regardless of demographic factors and BMI.

    People with undiagnosed celiac disease, as determined by positive blood tests, had lower average levels of B12 and folate than persons without celiac disease. People with a clinical celiac diagnosis diagnosis had a lower average level of hemoglobin than those without celiac disease.

    Both those with gluten-related conditions and those without showed comparable average levels of albumin, calcium, iron, ferritin, cholesterol, vitamin B6, and vitamin D.

    American living at latitudes of 35º North or greater have higher rates of celiac disease and/or avoid gluten than persons living south of this latitude, independent of race or ethnicity, socioeconomic status, or body mass index.

    Average levels of B12 and folate are lower in individuals with undiagnosed celiac disease, and levels of hemoglobin are lower in participants with a diagnosis of celiac disease, compared to individuals without celiac disease.

    I follow a strict glutenfree diet although never tested. Years ago I was found to be folic acid deficient, but no one picked up why I was, despite a good diet. I suffered from eczema, urticaria, alopecia, but no one linked these symptoms. When I omitted gluten I lost 1.5 stone, my constant indigestion disappeared, and the fatigue disappeared too. My sister and two of her children are coeliacs, we all live 54/55 degrees north.

    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 04/29/2013 - In an effort to determine the accuracy of claims that rates of celiac disease are on the rise, a team of researchers recently examined rates of celiac disease in a well-defined US county.
    The research team included Jonas F. Ludvigsson, Alberto Rubio-Tapia, Carol T. van Dyke, L. Joseph Melton, Alan R. Zinsmeister, Brian D. Lahr and Joseph A. Murray. They are variously affiliated with the Division of Gastroenterology and Hepatology in the Departments of Medicine and Immunology at the College of Medicine of the Mayo Clinic in Rochester, Minnesota, USA, and the Department of Pediatrics of Örebro University Hospital in Örebro, Sweden.
    For their population-based study, the team used medical, histopathology, and celiac disease serology records from the Rochester Epidemiology Project to identify all new cases of celiac disease in Olmsted County, Minnesota, USA since 2000.
    They then calculated age- and sex-specific incidence rates for celiac disease and adjusted those rates to the US white 2000 population. The team also assessed clinical presentation of celiac disease upon diagnosis.
    Overall, they found 249 cases of celiac disease, 92 cases in men and 157 cases in women, in Olmsted County, between 2000 and 2010. Average patient age was 37.9 years. Once adjusted for age and sex, the overall rate of celiac disease within the time studied was 17.4 (95% confidence interval (CI)=15.2–19.6) per 100,000 person-years. That means an increase of over six percent; from 11.1 per 100,000 person-years (95% CI=6.8–15.5) in 2000–2001. The data show the increase leveling off after 2004.
    The data also show that cases of celiac disease with classical symptoms of diarrhea and weight loss decreased over time between 2000 and 2010 (P=0.044).
    Overall, rates of celiac disease have continued to rise over the last decade in this North-American population. This study supports the observation that celiac disease rates in America are, in fact, going up.

    Celiac.com 09/09/2016 - Celiac disease incidence has increased in recent decades. How much do sex, age at diagnosis, year of birth, month of birth and region of birth have to do with celiac disease risk?
    A team of researchers recently conducted a nationwide prospective cohort longitudinal study to examine the association between celiac disease diagnosis and season of birth, region of birth and year of birth. The research team included Fredinah Namatovu, Marie Lindkvist, Cecilia Olsson, Anneli Ivarsson, and Olof Sandström. They are variously affiliated with the Department of Food and Nutrition, the Department of Clinical Sciences, Pediatrics, and the Department of Public Health and Clinical Medicine, Epidemiology and Global Health at Umeå University in Umeå, Sweden.
    Their study included 1,912,204 children aged 0–14.9 years born in Sweden from 1991 to 2009. They found a total of 6,569 children diagnosed with biopsy-verified celiac disease from 47 pediatric departments. The team used Cox regression to examine the association between celiac disease diagnosis and season of birth, region of birth and year of birth.
    They found that children born during spring, summer and autumn had higher celiac disease risk, as compared with children born during winter: adjusted HR for spring 1.08 (95% CI 1.01 to 1.16), summer 1.10 (95% CI 1.03 to 1.18) and autumn 1.10 (95% CI 1.02 to 1.18). Increased celiac disease risk was highest for children born in the south, followed by central Sweden, as compared with children born in northern Sweden.
    The birth cohort of 1991–1996 had increased celiac disease risk if born during spring, for the 1997–2002 birth cohort the risk increased for summer and autumn births, while for the birth cohort of 2003–2009 the risk was increased if born during autumn.
    Both independently and together, season of birth and region of birth are associated with increased risk of developing celiac disease during the first 15 years of life. These seasonal differences in risk levels are likely due to seasonal variation in infectious disease exposure.

    Celiac.com 09/26/2016 - Previous studies have indicated an increase in celiac disease rates in the United States, but these studies have been done on narrow populations, and did not produce results that are nationally representative.
    Researchers recently released an new comprehensive report, called, Time Trends in the Prevalence of Celiac Disease and Gluten-Free Diet in the US Population: Results From the National Health and Nutrition Examination Surveys 2009-2014. The research team included Hyun-seok Kim, MD, MPH; Kalpesh G. Patel, MD1; Evan Orosz, DO; Neil Kothari, MD; Michael F. Demyen, MD; Nikolaos Pyrsopoulos, MD, PhD, MBA; and Sushil K. Ahlawat, MD. They are variously affiliated with the Division of Gastroenterology and the Department of Medicine at Rutgers New Jersey Medical School in Newark.
    Using data from the National Health and Nutrition Examination Surveys, a team of researchers recently examined current trends in both celiac disease rates, and gluten-free diet adherence.
    Currently, far more people follow a gluten-free diet than have celiac disease. The numbers of people eating gluten-free food far outpace the levels of celiac disease diagnosis. This may be due to perceptions that the diet is healthier than a standard non-gluten-free diet.
    This research teams recent surveys examine the current trends in the prevalence of celiac disease and adherence to a gluten-free diet, including people without celiac disease, using nationally representative data from the National Health and Nutrition Examination Surveys (NHANESs) 2009-2014.
    The study evaluated 22,278 individuals over the age of 6 who completed surveys and blood tests for celiac disease. The subjects were interviewed directly regarding their prior diagnosis of celiac disease and adherence to a gluten-free diet.

    The researchers found that 106 (0.69%) individuals had a celiac disease diagnosis, and 213 (1.08%) followed a gluten-free diet but didn't have celiac disease. These results correlate to an estimated 1.76 million people with celiac disease, and 2.7 million people who follow a gluten-free diet without a diagnosis of celiac disease in the United States.

    Overall, the researchers found that the prevalence of celiac disease has remained steady (0.70% in 2009-2010, 0.77% in 2011-2012, and 0.58% in 2013-2014), however, those who follow a gluten-free diet but don't have celiac disease have increased over time (0.52% in 2009-2010, 0.99% in 2011-2012, and 1.69% in 2013-2014). The researchers conclude that the two might be related, as the decrease in gluten consumption could contribute to a plateau in those who are being diagnosed with celiac disease.

    Celiac.com 05/25/2018 - People with celiac disease need to follow a lifelong gluten-free diet. However, once their guts have healed, they can still be sensitive to gluten. Sometimes even more sensitive than they were before they went gluten-free. Accidental ingestion of gluten can trigger symptoms in celiac patients, such as pain in the gut and diarrhea, and can also cause intestinal damage. 
    A new drug being developed by a company called Amgen eases the effects of people with celiac disease on a gluten-free diet. Researchers working on the drug have announced that their proof-of-concept study shows AMG 714, an anti-IL-15 monoclonal antibody, potentially protects celiac patients from inadvertent gluten exposure by blocking interleukin 15, an important mediator of celiac disease, and leads to fewer symptoms following gluten exposure.
    The drug is intended for people with celiac disease who are following a gluten-free diet, and is designed to protect against modest gluten contamination, not to permit consumption of large amounts of gluten, like bread or pasta.
    AMG 714 is not designed for celiac patients to eat gluten at will, but for small, incidental contamination. Francisco Leon, MD, PhD, study director and consultant for Amgen, says that their team is looking at AMG 714 “for its potential to protect against modest contamination, not deliberately eating large amounts of gluten, like bread or pasta.” 
    Amgen hopes that AMG 714 will help celiac patients on a gluten-free diet to experience fewer or less sever gluten-triggered events.
    Findings of the team’s first phase 2 study of a biologic immune modulator in celiac disease will be presented at the upcoming Digestive Disease Week 2018.

    Celiac.com 05/24/2018 - England is facing some hard questions about gluten-free food prescriptions for people with celiac disease. Under England’s National Health Plan, people with celiac disease are eligible for gluten-free foods as part of their medical treatment. 
    The latest research shows that prescription practice for gluten-free foods varies widely, and often seems independent of medical factors. This news has put those prescribing practices under scrutiny.
    "Gluten free prescribing is clearly in a state of flux at the moment, with an apparent rapid reduction in prescribing nationally," say the researchers. Their data analysis revealed that after a steady increase in prescriptions between 1998 and 2010, the prescription rate for gluten free foods has both fallen, and become more variable, in recent years. Not only is there tremendous variation in gluten free prescribing, say the researchers, “this variation appears to exist largely without good reason…”
    Worse still, the research showed that those living in the most deprived areas of the country are the least likely to be prescribed gluten-free products, possibly due to a lower rate of celiac diagnosis in disadvantaged groups, say the researchers.
    But following a public consultation, the government decided earlier this year to restrict the range of gluten free products rather than banning them outright. As research data pile up and gluten-free food becomes cheaper and more ubiquitous, look for more changes to England’s gluten-free prescription program to follow.

    Celiac.com 05/23/2018 - Yes, we at Celiac.com realize that rye bread is not gluten-free, and is not suitable for consumption by people with celiac disease!  That is also true of rye bread that is low in FODMAPs.
    FODMAPs are Fermentable Oligosaccharides, Disaccharides, Monosaccharides and Polyols. FODMAPS are molecules found in food, and can be poorly absorbed by some people. Poor FODMAP absorption can cause celiac-like symptoms in some people. FODMAPs have recently emerged as possible culprits in both celiac disease and in irritable bowel syndrome.
    In an effort to determine what, if any, irritable bowel symptoms may triggered by FODMAPs, a team of researchers recently set out to compare the effects of regular vs low-FODMAP rye bread on irritable bowel syndrome (IBS) symptoms and to study gastrointestinal conditions with SmartPill.
    A team of researchers compared low-FODMAP rye bread with regular rye bread in patients irritable bowel syndrome, to see if rye bread low FODMAPs would reduce hydrogen excretion, lower intraluminal pressure, raise colonic pH, improve transit times, and reduce IBS symptoms compared to regular rye bread. The research team included Laura Pirkola, Reijo Laatikainen, Jussi Loponen, Sanna-Maria Hongisto, Markku Hillilä, Anu Nuora, Baoru Yang, Kaisa M Linderborg, and Riitta Freese.
    They are variously affiliated with the Clinic of Gastroenterology; the Division of Nutrition, Department of Food and Environmental Sciences; the Medical Faculty, Pharmacology, Medical Nutrition Physiology, University of Helsinki in Helsinki, Finland; the University of Helsinki and Helsinki University, Hospital Jorvi in Espoo, Finland; with the Food Chemistry and Food Development, Department of Biochemistry, University of Turku inTurku, Finland; and with the Fazer Group/ Fazer Bakeries Ltd in Vantaa, Finland.
    The team wanted to see if rye bread low in FODMAPs would cause reduced hydrogen excretion, lower intraluminal pressure, higher colonic pH, improved transit times, and fewer IBS symptoms than regular rye bread. 
    To do so, they conducted a randomized, double-blind, controlled cross-over meal study. For that study, seven female IBS patients ate study breads at three consecutive meals during one day. The diet was similar for both study periods except for the FODMAP content of the bread consumed during the study day.
    The team used SmartPill, an indigestible motility capsule, to measure intraluminal pH, transit time, and pressure. Their data showed that low-FODMAP rye bread reduced colonic fermentation compared with regular rye bread. They found no differences in pH, pressure, or transit times between the breads. They also found no difference between the two in terms of conditions in the gastrointestinal tract.
    They did note that the gastric residence of SmartPill was slower than expected. SmartPill left the stomach in less than 5 h only once in 14 measurements, and therefore did not follow on par with the rye bread bolus.
    There's been a great deal of interest in FODMAPs and their potential connection to celiac disease and gluten-intolerance. Stay tuned for more information on the role of FODMAPs in celiac disease and/or irritable bowel syndrome.

    Celiac.com 05/22/2018 - Proteins are the building blocks of life. If scientists can figure out how to create and grow new proteins, they can create new treatments and cures to a multitude of medical, biological and even environmental conditions.
    For a couple of decades now, scientists have been searching for a biological Rosetta stone that would allow them to engineer proteins with precision, but the problem has remained dauntingly complex.  Researchers had a pretty good understanding of the very simple way that the linear chemical code carried by strands of DNA translates into strings of amino acids in proteins. 
    But, one of the main problems in protein engineering has to do with the way proteins fold into their various three-dimensional structures. Until recently, no one has been able to decipher the rules that will predict how proteins fold into those three-dimensional structures.  So even if researchers were somehow able to design a protein with the right shape for a given job, they wouldn’t know how to go about making it from protein’s building blocks, the amino acids.
    But now, scientists like William DeGrado, a chemist at the University of California, San Francisco, and David Baker, director for the Institute for Protein Design at the University of Washington, say that designing proteins will become at least as important as manipulating DNA has been in the past couple of decades.
    After making slow, but incremental progress over the years, scientists have improved their ability to decipher the complex language of protein shapes. Among other things, they’ve gained a better understanding of how then the laws of physics cause the proteins to snap into folded origami-like structures based on the ways amino acids are attracted or repelled by others many places down the chain.
    It is this new ability to decipher the complex language of protein shapes that has fueled their progress. UCSF’s DeGrado is using these new breakthroughs to search for new medicines that will be more stable, both on the shelf and in the body. He is also looking for new ways to treat Alzheimer’s disease and similar neurological conditions, which result when brain proteins fold incorrectly and create toxic deposits.
    Meanwhile, Baker’s is working on a single vaccine that would protect against all strains of the influenza virus, along with a method for breaking down the gluten proteins in wheat, which could help to generate new treatments for people with celiac disease. 
    With new computing power, look for progress on the understanding, design, and construction of brain proteins. As understanding, design and construction improve, look for brain proteins to play a major role in disease research and treatment. This is all great news for people looking to improve our understanding and treatment of celiac disease.

    Celiac.com 05/21/2018 - Just a year ago, Starbucks debuted their Canadian bacon, egg and cheddar cheese gluten-free sandwich. During that year, the company basked in praise from customers with celiac disease and gluten-sensitivity for their commitment to delivering a safe gluten-free alternative to it’s standard breakfast offerings.
    But that commitment came to an ignoble end recently as Starbucks admitted that their gluten-free sandwich was plagued by  “low sales,” and was simply not sustainable from a company perspective. The sandwich may not have sold well, but it was much-loved by those who came to rely on it.
    With the end of that sandwich came the complaints. Customers on social media were anything but quiet, as seen in numerous posts, tweets and comments pointing out the callous and tone-deaf nature of the announcement which took place in the middle of national Celiac Disease Awareness Month. More than a few posts threatened to dump Starbucks altogether.
    A few of the choice tweets include the following:  
    “If I’m going to get coffee and can’t eat anything might as well be DD. #celiac so your eggbites won’t work for me,” tweeted @NotPerryMason. “They’re discontinuing my @Starbucks gluten-free sandwich which is super sad, but will save me money because I won’t have a reason to go to Starbucks and drop $50 a week,” tweeted @nwillard229. Starbucks is not giving up on gluten-free entirely, though. The company will still offer several items for customers who prefer gluten-free foods, including Sous Vide Egg Bites, a Marshmallow Dream Bar and Siggi’s yogurt.
    Stay tuned to learn more about Starbucks gluten-free foods going forward.
