    Celiac.com 11/28/2011 - Celiac disease often results in "leaky" intestinal mucosa. This development may involve changes in hydrophobicity of the mucus surface barrier along with changes of the epithelial barrier.

    A team of researchers recently compared bio-physical aspects of gastrointestinal mucosa of celiac patients with control subjects, along with the effects of gluten free diet on each group.

    Photo: CC -- spec-ta-clesThe research team included Stefania Bertolazzi, Francesco Lanzarotto, Barbara Zanini, Chiara Ricci, Vincenzo Villanacci, and Alberto Lanzini.

    The team set out to compare duodenal hydrophobicity as an index of mucus barrier integrity in 38 patients studied before and 68 patients during gluten-free diet, and in 90 control subjects. They also checked for regional differences of hydrophobicity in the gastro-intestinal tract.

    The team gauged hydrophobicity by measuring the contact angle (CA) (Rame Hart 100/10 goniometer) created by a single drop of water applied to intestinal mucosal biopsies.

    Once the team pooled the results and evaluated the control groups, patients with histologically normal duodenal biopsies showed significantly higher CA (620 + 90)  than patients with biopsies showing Marsh 1-2 (580 + 100; p<0.02) and Marsh 3 lesions (570+ 100; p<0.02).

    Among the control group, the action sequence of hydrofobicity along the gastrointestinal tract follows the pattern: gastric antrum> corpus> rectum> duodenum> oesophagus> ileum.

    From these results, the team concludes that people with celiac disease experience reduced hydrophobicity of duodenal mucous layer, and a reduced ability to repel luminal contents. This may may contribute to the increased intestinal permeability seen in celiac disease.

    This change in hydrofobicity corresponds to the severity of the mucosal lesions in the patient, and is not completely reversed by gluten-free diet.

    For celiacs gluten can irreversibly damage the intestinal lining, so that its contents "leak" into the rest of the body, a set-up for eventual major disease. At the moment, eating fresh food only and keeping one's environment gluten-free, are one's best defense.

    I understand that they are saying that we who are gluten-intolerant are not able to form a protective layer to keep the contents of our intestines inside (so some leaks out into the bloodstream). What do they mean, however, by that not being resolved by a gluten-free diet? Never? Do we always have a leaky gut? (I have heard that another gut gate-keeper that allows permeability, called Zonulin, also remains elevated in celiac disease--sounds like we're doomed!)

    Celiac.com 01/25/20010 - Women with celiac disease face greater risks for adverse pregnancy outcomes. A team of researchers recently set out to examine the effects of treated and untreated maternal celiac disease on infant birthweight and preterm birth. Among their findings are that expectant mothers with celiac disease face a higher risk of underweight and early-term birth than those without celiac disease.
    The research team included A.S. Khashan, T.B. Henriksen, P.B. Mortensen, R. McNamee, F.P. McCarthy, M.G. Pedersen and L.C. Kenny. They are affiliated variously with the Anu Research Centre of the Department of Obstetrics and Gynecology at the University College Cork at Cork University Maternity Hospital in Ireland, the Perinatal Epidemiology Research Unit in the Department of Paediatrics at Aarhus University Hospital, the National Centre for Register-based Research at the University of Aarhus, Denmark, and the Biostatistics Group, University of Manchester, Manchester, UK.
    For their data, they used a population-based cohort study of all live births in Denmark between 1 January 1979 and 31 December 2004. During that period, 836,241 mothers gave birth to a total of 1,504,342 babies. Mothers with diagnosed celiac disease gave birth to 1105 of those babies, while 346 were born to women with undiagnosed celiac disease.
    The team considered mothers with diagnosed celiac disease to be following a gluten free diet, and those with undiagnosed celiac disease to be on a gluten-inclusive diet. The team measured outcomes based on birthweight, small for gestational age (SGA: birthweight <10th centile), very small for gestational age (VSGA: birthweight <5th centile) and preterm birth. They then compared the results for the treated and untreated celiac disease mothers with those of a celiac-free reference group.
    The research team found that mothers with untreated celiac disease gave birth to smaller babies [difference = –98 g (95% CI: –130, –67)], with a higher risk of SGA [OR = 1.31 (95% CI: 1.06, 1.63)], VSGA [OR = 1.54 (95% CI: 1.17, 2.03)] and early birth [OR = 1.33 (95% CI: 1.02, 1.72)] compared with women with no celiac disease.
    The good news is that mothers with treated celiac disease showed no increased risk of reduced mean birthweight, or of delivering SGA and VSGA infants or preterm birth compared with mothers with no celiac disease.
    From the results, the research team concluded that untreated maternal celiac disease increases the risk of low birthweight, SGA and VSGA, and preterm birth.
    Diagnosis and treatment of maternal celiac disease with a gluten-free diet seems to return the birthweight and preterm birth rate to one comparable to women without celiac disease.
    This study drives home the importance of expectant mothers with celiac disease maintaining a gluten-free diet to promote a healthy delivery.

    Celiac.com 02/23/2011 - In most adults with celiac disease, clinical symptoms disappear with a gluten-free diet. However, the exact effects of a gluten-free diet on rates of mucosal recovery in adults with celiac disease is less certain.
    A group of clinicians recently set out to assess rates of mucosal recovery under a gluten-free diet in adults with celiac disease, and to gauge the clinical prospects of ongoing mucosal damage in celiac patients who follow a gluten-free diet.
    The study group included Alberto Rubio-Tapia, MD; Mussarat W. Rahim, MBBS; Jacalyn A. See, MS, RD, LD; Brian D. Lahr, MS; Tsung-Teh Wu, MD; and Joseph A. Murray, MD.
    Each patient in the study had biopsy-proven celiac disease, and was assessed at the Mayo Clinic. Also, each patient received duodenal biopsies at diagnosis. After beginning a gluten-free diet, each patient had at least one follow-up intestinal biopsy to assess mucosal recovery.
    The study team focused on mucosal recovery and overall mortality. Of 381 adult patients with biopsy-proven celiac disease, a total of 241 (175 women - 73%) had both a diagnostic and follow-up biopsy available for re-review.
    Using the Kaplan–Meier rate of confirmed mucosal recovery to assess these 241 patients, the study group found that 34% of the patients enjoyed mucosal recovery at 2 years after diagnosis (95% with a confidence interval (CI): 27–40 % ), and 66% of patients enjoyed mucosal recovery at 5 years (95% CI: 58–74 % ).
    More than 80% of patients showed some clinical response to the gluten-free diet, but clinical response was not a reliable marker of mucosal recovery ( P = 0.7). Serological response was, by far, the best marker for confirmed mucosal recovery ( P = 0.01).
    Patients who complied poorly with a gluten-free diet ( P < 0.01), those with severe celiac disease defined by diarrhea and weight loss ( P < 0.001), and those with total villous atrophy at diagnosis ( P < 0.001) had high rates of persistent mucosal damage.
    With adjustments for gender and age, patients who experienced confirmed mucosal recovery had lower mortality rates overall (hazard ratio = 0.13, 95 % CI: 0.02 – 1.06, P = 0.06).
    One of the most important findings from this study was that a large number of adults with celiac disease have no mucosal recovery, even after treatment with a gluten free diet.
    Compared to those patients who suffered persistent damage, patients who experienced confirmed mucosal recovery had lower rates of mortality independent of age and gender.
    The group notes that systematic follow-up via intestinal biopsy may be advisable for adults with celiac disease.

    Celiac.com 05/08/2013 - A team of researchers recently set out to test determine if an interactive online intervention might help to improve gluten free diet adherence in adults with celiac disease.
    The research team included Kirby Sainsbury BA/BEd, DCP (candidate), Barbara Mullan PhD and Louise Sharpe PhD. They are affiliated with the School of Psychology, and the Clinical Psychology Unit at the University of Sydney in Sydney, New South Wales, Australia
    For their controlled trial, the researchers recruited 189 adults with biopsy-confirmed celiac disease. They randomly assigned 101 adults to receive the intervention, and 88 adults to a wait-list control condition.
    They retrieved post-intervention data for 70 intervention subjects and 64 wait-list participants, along with three month follow-up data for 46 of 50 who completed the intervention period.
    The team first measured overall gluten-free diet adherence, then measured gluten-free diet knowledge, quality of life and psychological symptoms.
    The researchers based their results on intention-to-treat analysis, which bases their calculations on initial treatment assignment and not on the treatment eventually received.
    ITT analysis helps avoid various misleading factors that can color intervention research, such as non-random attrition of participants from the study or crossover.
    Overall, the intervention group showed strong improvement in gluten-free diet adherence, and gluten-free diet knowledge following the treatment period compared to the wait-list control group.
    However, changes in knowledge had no effect on adherence. These improvements continued through the 3-month’ follow-up period.
    The results show that the online intervention program helped improve adherence to a gluten-free diet for people with celiac disease. Such a program can be developed into a valuable resource for celiacs who are struggling with gluten-free diet adherence.

    Celiac.com 10/15/2014 - A team of researchers recently set out to assess the benefits of a gluten-free diet for people whose blood screens show markers for celiac disease, but who show no physical symptoms. Specifically, they investigated whether screen-detected and apparently asymptomatic adults with endomysial antibodies (EmA) benefit from a gluten-free diet.
    The research team included K. Kurppa, A. Paavola, P. Collin, H. Sievänen, K. Laurila, H. Huhtala, P. Saavalainen, M. Mäki, and K. Kaukinen. They are variously associated with the Tampere Center for Child Health Research, the Tampere School of Health Sciences of the University of Tampere and Tampere University Hospital, the Department of Gastroenterology and Alimentary Tract Surgery at Tampere University Hospital and School of Medicine, University of Tampere, the UKK Institute in Tampere, Finland, the Research Program Unit of the Immunobiology and Haartman Institute at the Department of Medical Genetics of the University of Helsinki in Helsinki, Finland, and the Department of Gastroenterology and Alimentary Tract Surgery, Tampere University Hospital and School of Medicine, University of Tampere, Tampere, Finland and Seinäjoki Central Hospital, Seinäjoki, Finland.
    For their study, they conducted a prospective trial of 3031 individuals at risk for celiac disease based on screens for EmA. They found 40 of 148 seropositive individuals who fulfilled inclusion criteria. They randomly assigned the 40 patients to groups receiving either a gluten-free diet, or a gluten-containing diet.
    They then evaluated ratios of small-bowel mucosal villous height:crypt depth, serology and laboratory test results, gastrointestinal symptom scores, physiologic well-being, perception of health by a visual analog scale, bone mineral density, and body composition at baseline and after 1 year. From that point on, they switched the group on the gluten-containing diet to a gluten-free diet, evaluated them a third time. Patients in the first gluten-free diet group remained on that diet.
    After 1 year on the gluten-free diet, the mean mucosal villous height:crypt depth values increased (P < .001), levels of celiac-associated antibodies decreased (P < .003), and gastrointestinal symptoms improved compared to patients on gluten-containing diets (P = .003).
    The gluten-free diet group showed less indigestion (P = .006), reflux (P = .05), and anxiety (P = .025), and better overall health, based on the visual analog scale (P = .017), compared gluten-containing diet group.
    Only social function scores improved more in the gluten-containing diet group than in the gluten-free diet group (P = .031). There were no differences between groups in terms of lab test results, bone mineral density, or body composition.
    Most measured parameters improved when patients in the gluten-containing diet group were placed on gluten-free diets.
    No subjects considered their experience to be negative and most expected to continue eating gluten-free.
    The results show that a gluten-free diet benefits asymptomatic EmA-positive patients, and show the benefits of actively screening patients at risk for celiac disease.

    Celiac.com 06/22/2018 - The rise of food allergies means that many people are avoiding gluten in recent times. In fact, the number of Americans who have stopped eating gluten has tripled in eight years
    between 2009 and 2017.
    Whatever your rationale for avoiding gluten, whether its coeliac disease, a sensitivity to the
    protein, or any other reason, it can be really hard to find suitable places to eat out. When
    you’re on holiday in a new and unknown environment, this can be near impossible.
    As awareness of coeliac disease grows around the world, however, more and more cities
    are opening their doors to gluten-free lifestyles, none more so than the 10 locations on the
    list below.
    Perhaps unsurprisingly, the U.S is a hotbed of gluten-free options, with four cities making the
    top 10, as well as the Hawaiian island of Maui. Chicago, in particular, is a real haven of
    gluten-free fare, with 240 coeliac-safe eateries throughout this huge city.
    The super hip city of Portland also ranks highly on this list, with the capital of counterculture
    rich in gluten-free cuisine, with San Francisco and Denver also included.
    Outside of the states, several prominent European capitals also rank very highly on the list,
    including Prague, the picturesque and historic capital of the Czech Republic, which boasts
    the best-reviewed restaurants on this list.
    The Irish capital of Dublin, meanwhile, has the most gluten-free establishments, with a huge
    330 to choose from, while Amsterdam and Barcelona also feature prominently thanks to their
    variety of top-notch gluten-free fodder.
    Finally, a special mention must go to Auckland, the sole representative of Australasia in this
    list, with the largest city in New Zealand rounding out the top 10 thanks to its 180 coeliacsafe
    eateries.
    The full top ten gluten-free cities are shown in the graphic below:

    Celiac.com 06/21/2018 - Would you buy a house advertised as ‘gluten-free’? Yes, there really is such a house for sale. 
    It seems a Phoenix realtor Mike D’Elena is hoping that his trendy claim will catch the eye of a buyer hungry to avoid gluten, or, at least one with a sense of humor. D’Elena said he crafted the ads as a way to “be funny and to draw attention.” The idea, D’Elena said, is to “make it memorable.” 
    Though D’Elena’s marketing seeks to capitalizes on the gluten-free trend, he knows Celiac disease is a serious health issue for some people. “[W]e’re not here to offend anybody….this is just something we're just trying to do to draw attention and do what's best for our clients," he said. 
    Still, the signs seem to be working. D'elena had fielded six offers within a few days of listing the west Phoenix home.
    "Buying can sometimes be the most stressful thing you do in your entire life so why not have some fun with it," he said. 
    What do you think? Clever? Funny?

    Celiac.com 06/20/2018 - Currently, the only way to manage celiac disease is to eliminate gluten from the diet. That could be set to change as clinical trials begin in Australia for a new vaccine that aims to switch off the immune response to gluten. 
    The trials are set to begin at Australia’s University of the Sunshine Coast Clinical Trials Centre. The vaccine is designed to allow people with celiac disease to consume gluten with no adverse effects. A successful vaccine could be the beginning of the end for the gluten-free diet as the only currently viable treatment for celiac disease. That could be a massive breakthrough for people with celiac disease.
    USC’s Clinical Trials Centre Director Lucas Litewka said trial participants would receive an injection of the vaccine twice a week for seven weeks. The trials will be conducted alongside gastroenterologist Dr. James Daveson, who called the vaccine “a very exciting potential new therapy that has been undergoing clinical trials for several years now.”
    Dr. Daveson said the investigational vaccine might potentially restore gluten tolerance to people with celiac disease.The trial is open to adults between the ages of 18 and 70 who have clinically diagnosed celiac disease, and have followed a strict gluten-free diet for at least 12 months. Anyone interested in participating can go to www.joinourtrials.com.

    Celiac.com 06/19/2018 - Could baking soda help reduce the inflammation and damage caused by autoimmune diseases like rheumatoid arthritis, and celiac disease? Scientists at the Medical College of Georgia at Augusta University say that a daily dose of baking soda may in fact help reduce inflammation and damage caused by autoimmune diseases like rheumatoid arthritis, and celiac disease.
    Those scientists recently gathered some of the first evidence to show that cheap, over-the-counter antacids can prompt the spleen to promote an anti-inflammatory environment that could be helpful in combating inflammatory disease.
    A type of cell called mesothelial cells line our body cavities, like the digestive tract. They have little fingers, called microvilli, that sense the environment, and warn the organs they cover that there is an invader and an immune response is needed.
    The team’s data shows that when rats or healthy people drink a solution of baking soda, the stomach makes more acid, which causes mesothelial cells on the outside of the spleen to tell the spleen to go easy on the immune response.  "It's most likely a hamburger not a bacterial infection," is basically the message, says Dr. Paul O'Connor, renal physiologist in the MCG Department of Physiology at Augusta University and the study's corresponding author.
    That message, which is transmitted with help from a chemical messenger called acetylcholine, seems to encourage the gut to shift against inflammation, say the scientists.
    In patients who drank water with baking soda for two weeks, immune cells called macrophages, shifted from primarily those that promote inflammation, called M1, to those that reduce it, called M2. "The shift from inflammatory to an anti-inflammatory profile is happening everywhere," O'Connor says. "We saw it in the kidneys, we saw it in the spleen, now we see it in the peripheral blood."
    O'Connor hopes drinking baking soda can one day produce similar results for people with autoimmune disease. "You are not really turning anything off or on, you are just pushing it toward one side by giving an anti-inflammatory stimulus," he says, in this case, away from harmful inflammation. "It's potentially a really safe way to treat inflammatory disease."
    The research was funded by the National Institutes of Health.
