    Celiac.com 06/26/2007 - The results of a study recently published in the online science journal Nature Genetics have revealed a previously unknown genetic risk factor for celiac disease. An international team of researchers set out to study the genetic causes of intestinal inflammatory disorders. When the study began, it was well known that individuals with celiac disease have specific tissue types that identify wheat proteins. Why healthy individuals with the same tissue type failed to develop celiac symptoms or celiac disease remained unknown, and was a key question the team set out to answer. The team was led David van Heel, Professor of Gastrointestinal Genetics at Queen Mary, University of London. The Human Genome Project and the Hap Map Project played key support roles in the study.
    The results show that a protective DNA sequence in a specific gene segment, generally found in healthy individuals are missing in people with celiac disease. The research team evaluated genome data of 778 individuals with celiac disease and 1,422 controls non-celiacs within the British, Irish and Dutch populations.
    Key DNA Sequence Missing in Celiacs
    Researchers discovered that, compared to people with celiac disease, healthy people more commonly have a DNA sequence in the interleukin-2 and interleukin-21 gene region that protects against celiac disease. Interleukin-2 and interleukin-21 are cytokine proteins that are secreted by white blood cells, and which control inflammation. In people with celiac disease, the protective DNA sequence most likely leads to lesser amounts of these cytokines being produced, which weakens the defense against intestinal inflammation.
    Breakthrough in Better Understanding Risk Factors for Development of Celiac Disease
    About 1 in 133 people develop the disease, but, so far, predicting those at risk to develop the disease has been haphazard at best. Present methods of genetic testing can only narrow down the search to about 30% of the general population. These results give doctors a means to discover what further genetic risk factors leave people vulnerable to developing celiac disease.

    Increased Expression of Hypoxia Inducible Factor 1alpha in Celiac Disease
    Celiac.com 06/01/2010 - A clinical research team recently examined the increased expression of hypoxia inducible factor 1alpha in celiac disease. The team included A. Vannay, E. Sziksz, A. Prókai, G. Veres, K. Molnár, D. Nagy Szakál, A. Onódy, I. R. Korponay-Szabó, A. Szabó, T. Tulassay, A. Arató, and B. Szebeni.
    They are affiliated with the First Department of Pediatrics at Semmelweis University, and with the Department of Gastroenterology-Nephrology of Heim Pal Children's Hospital, both in Budapest, Hungary. They are also involved with the Research Group for Pediatrics and Nephrology, a joint project between the two institutions.
    The team set out to follow-up on the hypothesis that hypoxia inducible factor (HIF) 1 signaling may play a key role in maintaining the barrier function of the intestinal epithelium in cases of inflammatory bowel disease (IBD).
    In their 2008 article, "The human side of hypoxia-inducible factor," which appeared in the British Journal of Haematology, Smith, Robbins and Ratcliffe define Hypoxia-inducible factors (HIFs) as transcription factors that respond to changes in available oxygen in the cellular environment, specifically, to decreases in oxygen, or hypoxia.
    The team wanted to characterize the variation of HIF-1alpha and related genes in celiac disease, where the importance of the barrier function is well understood.
    To accomplish their goal, they gathered duodenal biopsy specimens from 16 children with untreated celiac disease, 9 children with treated celiac disease, and 10 control subjects.
    They assessed HIF-1alpha, trefoil factor 1 (TFF1), ecto-5-prime nucleotidase (CD73) and multi-drug resistance gene 1 (MDR1) mRNA and HIF-1alpha protein expression by real-time PCR and Western blot, respectively. They assessed localization of HIF-1alpha by immunofluorescent staining.
    The team observed increased HIF-1alpha and TFF1 mRNA and HIF-1alpha protein expression in the duodenal mucosa of children with untreated celiac disease compared to either the control subjects, or those with treated celiac disease (p<0.05).
    Children with untreated celiac disease showed HIF-1alpha staining in cytoplasmic and nuclear region of the villous enterocytes.
    Children with treated celiac disease showed increased mRNA expression of CD73 and MDR1 versus control subjects (p<0.01 and 0.05, respectively).
    The results of increased mucosal HIF-1alpha expression in children with celiac disease suggests influences from this signaling pathway in the pathological mechanisms of celiac disease.

    A Gluten Free Diet May Alleviate Gastroesophageal Reflux Symptoms in People with Celiac Disease
    Celiac.com 12/16/2011 - To date, symptoms of gastroesophageal reflux disease (GERD) - heartburn and acid regurgitation - have been among the only GI symptoms absent from the list of common manifestations of celiac disease. They are usually definitive indicators of gastric acid reflux. But a report from Julio César Bai's group in Buenos Aires notes that at the time of diagnosis, patients with celiac disease were more likely to complain of GERD symptoms than healthy controls. Moreover, maintaining a gluten free diet alleviated these symptoms. Their results are reported in Clinical Gastroenterology and Hepatology.GERD is a chronic condition usually resulting from the reflux of acidic stomach contents up into the esophagus. It is commonly treated with proton pump inhibitors, but some cases are refractory to this treatment. There has been conflicting data as to whether GERD symptoms are more common in people with celiac, and whether a gluten free diet might help. Dr. Bai's group designed a two pronged study to answer these questions: They undertook a cross sectional analysis of 133 people upon their diagnosis with celiac over the course of 2005, and a longitudinal assessment of 53 of them as they maintained a gluten free diet over the next four years.
    At the time of their diagnosis, the proportion of celiac with reflux was six-fold higher than that in the the 70 healthy controls included in the study. Interestingly, more severe reflux symptoms were associated with the classical, rather than the silent, presentation of celiac disease. However, it should be noted that this was somewhat of a selected population; these data were obtained from patients coming to a malabsorption clinic, where the classic presentation of celiac is more prevalent than the silent type. Moreover, for whatever reason, these healthy volunteers had less GERD symptoms than is usually reported. After three months on a gluten free diet symptoms were comparable to those seen in healthy controls. Interestingly, though, this was the case for patients who reported only partially complying to a gluten free diet as well as those who adhered to it strictly.
    Because these symptoms are alleviated upon assumption of a gluten free diet, the authors hypothesize that they might be caused by a nontraditional mechanism in celiac patients rather than by actual reflux. One suggestion they posit is reduced upper gastrointestinal motility, and another is a permeability defect in the stratified esophageal epithelium. In an editorial accompanying the paper, delayed gastric emptying and disturbed neuroendocrine control of upper GI function are floated potentially contributing to GERD symptoms in untreated celiac. Further research would have to be done to bear out these and other ideas.

    New Study Points to Antibiotics as Celiac Disease Risk Factor
    Celiac.com 07/22/2013 - Celiac disease is known to be caused by a combination of genetic and environmental factors. The genetic markers are fairly well established by now, but the environmental factors that are associated with celiac disease are still pretty foggy. A recent study suggests that antibiotic use might be one such factor.
    In a population-based case-control study analyzing Swedish population data, antibiotic use was compared against diagnosis of celiac disease. 2,933 people with celiac disease diagnoses were linked to the Swedish Prescribed Drug Register, in order to provide a history of antibiotic use. 2,118 people with inflammation (early celiac disease) and 620 people with normal mucosa but positive celiac disease blood test results were also compared. The control group consisted of 28,262 individuals matched for age and sex from the general population.
    The results of the study significantly suggest that antibiotic use is associated with celiac disease, at an odds ratio of 1.4 (1.27-1.53 confidence interval). Early celiac disease was also connected, with an odds ratio of 1.90 (1.72-2.10 confidence ratio), as well as positive celiac disease blood tests, at 1.58 odds ratio (1.30-1.92 confidence interval). Even when antibiotic use in the last year was ruled out, the results were very similar at 1.30 odds ratio (1.08-1.56 confidence interval). When ruling out patients with additional diseases, which could potentially be factors, the results were also very similar at 1.30 odds ratio (1.16-1.46 confidence interval).
    What does all that mean? A 1.4 odds ratio basically means that people who had a history of antibiotic use were 1.4 times as likely as those who had not taken antibiotics to develop celiac disease. The fact that inflammation associated with early celiac disease was also highly connected suggests that antibiotics' role in disrupting the biology of the GI tract could in some way cause celiac disease. There is still some question of causality, but it would seem that antibiotics could very likely be a culprit in the development of celiac disease, and should be avoided when possible.

    Could Gluten-Free Food Be Hurting Your Dog?
    Celiac.com 08/15/2018 - Grain-free food has been linked to heart disease in dogs. A canine cardiovascular disease that has historically been seen in just a few breeds is becoming more common in other breeds, and one possible culprit is grain-free dog food. 
    The disease in question is called canine dilated cardiomyopathy (DCM), and often results in congestive heart failure. DCM is historically common in large dogs such as Great Danes, Newfoundlands, Irish Wolfhounds, Saint Bernards and Doberman Pinschers, though it is also affects some Cocker Spaniels.  Numerous cases of DCM have been reported in smaller dogs, whose primary source of nutrition was food containing peas, lentils, other legume seeds or potatoes as main ingredients. These reported atypical DCM cases included Golden and Labrador Retrievers, a Whippet, a Shih Tzu, a Bulldog and Miniature Schnauzers, as well as mixed breeds. 
    As a result, the U.S. Food and Drug Administration's Center for Veterinary Medicine, along with a group of veterinary diagnostic laboratories, is investigating the possible link between DCM and pet foods containing seeds or potatoes as main ingredients. The good news is that in cases where the dog suffers no genetic component, and the disease is caught early, simple veterinary treatment and dietary change may improve heart function.
    According to Nutritional Outlook, an industry publication for makers of dietary supplements and healthy foods and beverages, there is a growing market for “free from” foods for dogs, especially gluten-free and grain-free formulations. In 2017, about one in five dog foods launched was gluten-free. So, do dogs really need to eat grain-free or gluten-free food? Probably not, according to PetMD, which notes that many pet owners are simply projecting their own food biases when choosing dog food.
    Genetically, dogs are well adapted to easily digest grains and other carbohydrates. Also, beef and dairy remain the most common allergens for dogs, so even dogs with allergies are unlikely to need to need grain-free food. 
    So, the take away here seems to be that most dogs don’t need grain-free or gluten-free food, and that it might actually be bad for the dog, not good, as the owner might imagine.
    Stay tuned for more on the FDA’s investigation and any findings they make.

    Did You Miss the Gluten-Free Fireworks This Past Fourth of July?
    Celiac.com 08/14/2018 - Occasionally, Celiac.com learns of an amusing gluten-free story after the fact. Such is the case of the “Gluten-Free Fireworks.” 
    We recently learned about a funny little event that happened leading up to Fourth of July celebrations in the town of Springdale in Northwest Arkansas. It seems that a sign advertising "Gluten Free Fireworks" popped up near a fireworks stand on interstate 49 in Springdale. 
    In case you missed the recent dose of Fourth of July humor, in an effort to attract customers and provide a bit of holiday levity, Pinnacle Fireworks put up a sign advertising "gluten-free fireworks.” 
    The small company is owned by Adam Keeley and his father. "A lot of the people that come in want to crack a joke right along with you," Keeley said. "Every now and then, you will get someone that comes in and says so fireworks are supposed to be gluten-free right? Have I been buying fireworks that have gluten? So then I say no, no they are gluten-free. It's just a little fun."
    Keeley said that their stand saw a steady flow of customers in the week leading up to the Fourth. In addition to selling “gluten-free” fireworks, each fireworks package sold by Pinnacle features a QR code. The code can be scanned with a smartphone. The link leads to a video showing what the fireworks look like.
    We at Celiac.com hope you and your family had a safe, enjoyable, and, yes, gluten-free Fourth of July. Stay tuned for more on gluten-free fireworks and other zany, tongue-in-cheek stories.

    Stress-Related Disorders Associated with Higher Risk for Autoimmune Disease
    Celiac.com 08/13/2018 - It’s not uncommon for people to have psychiatric reactions to stressful life events, and these reactions may trigger some immune dysfunction. Researchers don’t yet know whether such reactions increase overall risk of autoimmune disease.
    Are psychiatric reactions induced by trauma or other life stressors associated with subsequent risk of autoimmune disease? Are stress-related disorders significantly associated with risk of subsequent autoimmune disease?
    A team of researchers recently set out to determine whether there is an association between stress-related disorders and subsequent autoimmune disease. The research team included Huan Song, MD, PhD; Fang Fang, MD, PhD; Gunnar Tomasson, MD, PhD; Filip K. Arnberg, PhD; David Mataix-Cols, PhD; Lorena Fernández de la Cruz, PhD; Catarina Almqvist, MD, PhD; Katja Fall, MD, PhD; Unnur A. Valdimarsdóttir, PhD.
    They are variously affiliated with the Center of Public Health Sciences, Faculty of Medicine, University of Iceland, Reykjavík, Iceland; the Department of Medical Epidemiology and Biostatistics, Karolinska Institutet, Stockholm, Sweden; the Department of Epidemiology and Biostatistics, Faculty of Medicine, University of Iceland, Reykjavík, Iceland; the Department of Rheumatology, University Hospital, Reykjavík, Iceland; the Centre for Rheumatology Research, University Hospital, Reykjavík, Iceland; the National Centre for Disaster Psychiatry, Department of Neuroscience, Psychiatry, Uppsala University, Uppsala, Sweden; the Stress Research Institute, Stockholm University, Stockholm, Sweden; the Centre for Psychiatry Research, Department of Clinical Neuroscience, Karolinska Institutet, Stockholm, Sweden; the Stockholm Health Care Services, Stockholm County Council, Stockholm, Sweden; the Astrid Lindgren Children’s Hospital, Karolinska University Hospital, Stockholm, Sweden; the Clinical Epidemiology and Biostatistics, School of Medical Sciences, Örebro University, Örebro, Sweden; the Department of Medical Epidemiology and Biostatistics, Karolinska Institutet, Stockholm, Sweden; and the Department of Epidemiology, Harvard T.H. Chan School of Public Health, Boston, Massachusetts.
    The team conducted a Swedish register-based retrospective cohort study that included 106, 464 patients with stress-related disorders, 1,064 ,640 matched unexposed individuals, and 126 ,652 full siblings to determine whether a clinical diagnosis of stress-related disorders was significantly associated with an increased risk of autoimmune disease.
    The team identified stress-related disorder and autoimmune diseases using the National Patient Register. They used Cox model to estimate hazard ratios (HRs) with 95% CIs of 41 autoimmune diseases beyond 1 year after the diagnosis of stress-related disorders, controlling for multiple risk factors.
    The data showed that being diagnosed with a stress-related disorder, such as post-traumatic stress disorder, acute stress reaction, adjustment disorder, and other stress reactions, was significantly associated with an increased risk of autoimmune disease, compared with matched unexposed individuals. The team is calling for further studies to better understand the associations and the underlying factors.

    Five-Minute Healthy Breakfasts
    Celiac.com 08/10/2018 - You’ve heard for years that it’s wise to start your day with a healthy breakfast.  Eating food first thing in the morning gets your metabolism revved so you have energy throughout the day.  There’s also the issue of incorporating healthy foods into your first meal of the day.  Ideally, every meal should include fiber and foods from a variety of food groups.  But the reality is that most people don’t have time in the morning to create an involved meal.  You’re busy getting ready for work, packing the kids’ lunches and trying to get everyone out of the door on time.  
    Don’t fret.  The task of preparing a healthy breakfast just got easier.  You can make 5-minute breakfasts and, with a little bit of planning, you can sneak fiber into those meals without spending a lot of extra time with preparation.  An ideal breakfast will include whole grains (from gluten-free cereals, breads, muffins, or uncontaminated oats), a low-fat dairy item (1% milk, low-fat yogurt, or low-fat cheese), and a source of protein (such as peanut butter or eggs).  Adding fruit is a plus.  
    If you can tolerate uncontaminated oats, make a bowl of oatmeal and add a little extra fiber by stirring in chopped walnuts and dried cranberries.  If you like scrambled eggs, toss some fresh spinach (sliced into thin strips), 1 chopped canned artichoke heart, two tablespoons crumbled feta cheese, and a dash of Italian seasoning to the egg as it cooks.  
    If you have time on weekends to make healthy gluten-free pancakes (which  means that you added perhaps flax seed meal or shredded apples or something that qualifies as fiber to the batter), then freeze the pancakes between sheets of wax paper, place them in a freezer bag, and freeze so they’ll be handy on busy weekday mornings.  If you don’t have time to make them prior to need, you can always use commercial frozen gluten-free pancakes.  In a bowl, mix together a few raisins, half of a chopped pear or apple, a few dashes of cinnamon and a couple of tablespoons of chopped walnuts.  Spoon this mixture down the centers of two toasted (or microwaved) pancakes, drizzle each with 1 teaspoon of pancake or maple syrup, then fold in the sides of the pancakes to make two breakfast sandwiches.
    Brown rice is brown because the bran layer is still on the rice, and the bran layer is the part that’s so high in fiber.  White rice is much lower in fiber and has less nutritional value.  Brown rice isn’t just for dinner anymore.  It offers a nice breakfast alternative from traditional hot cereals.  The next time you make brown rice for dinner, make a little extra and save some for breakfast the next morning.  In the A.M., mix the rice (about 1 cup) with a few chopped pecans, a few raisins, 1/2 cup milk, 3 tablespoons pancake syrup, a dash each of vanilla and cinnamon, then microwave the mixture for 1 minute, stirring once after 30 seconds.  Let it sit for 30 seconds to thicken before eating.  Or stir together 1 cup cooked brown rice, 1/4 teaspoon cinnamon, 1/2 navel orange diced, some chopped dates, dried cranberries, and shredded coconut; heat this in the microwave and then top it off with 1/2 cup low-fat vanilla yogurt.
    Just a note about using the microwave—it’s not an exact science.  Different ovens have different power levels so what cooks in 30 seconds in one person’s microwave may take 45 seconds in someone else’s unit.  Unless you want the food to splatter all over the sides of the oven, you’ll need to cover any liquids or soft foods with waxed paper.  
    There will be days when you don’t have time to sit down at the table and enjoy a leisurely breakfast.  On these days, make a “grab-and-go” breakfast that you can take with you.  Gluten-free wraps keep for several weeks in the refrigerator and they make great fill-and-go containers on busy mornings.  Spread a wrap with peanut butter, sprinkle some fortified gluten-free dry cereal on top, then drizzle with a teaspoon of pancake syrup; roll up the wrap and you have the perfect dashboard dining breakfast to eat on the way to work.  Or scramble an egg, spoon it down the center of the wrap, and then top it off with a little salsa and pepper-jack cheese before rolling it up. If you only have three minutes before you have to leave the house, spoon some low-fat cottage cheese into a cup, stir in a dash of cinnamon, top with a little low-fat gluten-free granola or fortified dry gluten-free cereal, sprinkle berries or chopped peaches over the top, grab a spoon, and you’re ready to go!
    Smoothies can be made in literally one minute.  Toss some frozen raspberries into a blender, add a 12-ounce container of low-fat lemon yogurt, a little milk, and two teaspoons of vanilla; blend, then pour the mixture into a large plastic cup.
    If you oversleep, don’t panic.  Have some back-up foods on hand that you can grab and eat en route to work, like a gluten-free protein bar and a banana, or a bag of nuts and dried fruit, or flax seed crackers with a handful of cheese cubes, or toss some gluten-free granola over a container of yogurt and grab a spoon to take along.
    All of the above suggestions can be made in five minutes or less.  Take the time to start your day off with a healthy breakfast—you deserve to do that for yourself and for your family.
    Apple English Muffins by Connie Sarros
    This recipe is from my newly-released book Student’s Vegetarian Cookbook for Dummies.  While this isn’t a gluten-free cookbook, most of the recipes are naturally gluten-free or can very easily be converted to gluten-free.  
    Preparation time:  4 minutes.  Cooking time:  30 seconds.  Yield:  1 serving
    Ingredients:
    1 tablespoon peanut butter  1 gluten-free English muffin, toasted  1/8 large apple, peeled, cored and sliced thin ½ teaspoon butter  ¾ teaspoon brown sugar 1/8 teaspoon cinnamon Directions:
    Spread peanut butter on one toasted English muffin half.  Lay the apple slices on top. In a small microwave safe bowl, heat the butter in the microwave on high for 15 seconds.  Stir in the brown sugar and cinnamon then nuke for another 15 seconds.  Stir until smooth.  (If necessary, pop it back into the microwave until the brown sugar melts).   Drizzle the cinnamon mixture over the apple slices then place the second half of the English muffin on top. Note:  If you’re out of apples, use a pear, ripe peach or nectarine, mango, or even a banana.
