    Photo: Wikimedia Commons.The new blood test is supposedly accurate after only three days of gluten consumption, not the several weeks or months traditionally required to make a diagnosis using intestinal biopsies.

    Researchers from the Melbourne institute, with colleagues from biotechnology company ImmusanT in Boston, US, led a study of the blood test in 48 participants, the results of which were published in the journal Clinical & Experimental Immunology.

    Furthermore, says Dr Jason Tye-Din, gastroenterologist and head of celiac research at Hall, preliminary results show that the new diagnostic test can accurately detect celiac disease within 24 hours.

    Dr Tye-Din said that the blood test built on fundamental research discoveries the team had made about coeliac disease.

    "This 'cytokine release' test measures the T cell response to gluten after three days of consumption, and a positive response is highly predictive of coeliac disease," he said. "With this test, we were able to detect a T cell response in the majority of study participants known to have coeliac disease and importantly, the test was negative in all of the patients who did not have coeliac disease, even though they followed a gluten-free diet and thought gluten was the cause of their symptoms."

    The researchers hope larger studies will confirm its role as a widely used tool for diagnosing coeliac disease.

    I have concerns about this study and the accuracy of this new test. My understanding is that there is currently no way to test someone who is already gluten-free. Therefore, how did the researchers confirm that their test accurately picked up those who were on a gluten-free diet but did not have celiac disease?

    I'm happy that more reliable tests are being developed, but I don't want to have to hurt myself to prove to doctors that I have a disease I know I have. It's a step in the right direction, though, so I'm hopeful that progress in identifying patients with celiac disease will get easier and that more doctors will begin to understand this condition.

    This article does not show how participants were determined to have or not have celiac disease. There is no information about the cost and availability of the test (in the future I assume).

    Celiac.com 01/01/2014 - By enabling researchers to link antibodies with certain diseases, a new method could help uncover and confirm environmental triggers for diseases such as celiac and autism.
    The researchers have two goals, according to professor Patrick Daugherty, a researcher with the department of chemical engineering and the Center for BioEngineering at University of California, Santa Barbara.
    First, they want to create diagnostic tests for diseases for which there are currently no blood tests. Next, they want to figure out what causes the diseases.
    The process works by mining an individual’s immunological memory—a veritable catalog of the pathogens and antigens encountered by his or her immune system
    Every time we encounter a pathogen, our bodies mounts an immune response in the form of antibodies that are specific for given antigens; molecular, microbial, chemical, etc. Each time our bodies mount this response, they form “memory cells” that are activated by subsequent encounters with that specific antigen. Responses can vary, from minor reactions to serious autoimmune diseases in which the body turns against its own tissues and its immune system responds by destroying them, such as in the case of Type 1 diabetes and celiac disease.
    People with celiac disease, for example, will have certain antibodies in their blood that bind to specific peptides—short chains of amino acids—present in wheat, barley, and rye. These peptides are the gluten that trigger adverse reactions in certain people. In the same way that a lock is meant to take only one key, these antibodies will only attach to specific sequences of amino acids that make up the peptides.
    The researchers want to figure out which antibodies are linked to specific diseases. “People with celiac disease have two particular antibody types in their blood, which have proved to be enormously useful for diagnosis,” says Daugherty.

    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.

    Celiac.com 06/18/2018 - Celiac disease has been mainly associated with Caucasian populations in Northern Europe, and their descendants in other countries, but new scientific evidence is beginning to challenge that view. Still, the exact global prevalence of celiac disease remains unknown.  To get better data on that issue, a team of researchers recently conducted a comprehensive review and meta-analysis to get a reasonably accurate estimate the global prevalence of celiac disease. 
    The research team included P Singh, A Arora, TA Strand, DA Leffler, C Catassi, PH Green, CP Kelly, V Ahuja, and GK Makharia. They are variously affiliated with the Division of Gastroenterology and Hepatology, Beth Israel Deaconess Medical Center, Boston, Massachusetts; Lady Hardinge Medical College, New Delhi, India; Innlandet Hospital Trust, Lillehammer, Norway; Centre for International Health, University of Bergen, Bergen, Norway; Division of Gastroenterology and Hepatology, Beth Israel Deaconess Medical Center, Boston, Massachusetts; Gastroenterology Research and Development, Takeda Pharmaceuticals Inc, Cambridge, MA; Department of Pediatrics, Università Politecnica delle Marche, Ancona, Italy; Department of Medicine, Columbia University Medical Center, New York, New York; USA Celiac Disease Center, Columbia University Medical Center, New York, New York; and the Department of Gastroenterology and Human Nutrition, All India Institute of Medical Sciences, New Delhi, India.
    For their review, the team searched Medline, PubMed, and EMBASE for the keywords ‘celiac disease,’ ‘celiac,’ ‘tissue transglutaminase antibody,’ ‘anti-endomysium antibody,’ ‘endomysial antibody,’ and ‘prevalence’ for studies published from January 1991 through March 2016. 
    The team cross-referenced each article with the words ‘Asia,’ ‘Europe,’ ‘Africa,’ ‘South America,’ ‘North America,’ and ‘Australia.’ They defined celiac diagnosis based on European Society of Pediatric Gastroenterology, Hepatology, and Nutrition guidelines. The team used 96 articles of 3,843 articles in their final analysis.
    Overall global prevalence of celiac disease was 1.4% in 275,818 individuals, based on positive blood tests for anti-tissue transglutaminase and/or anti-endomysial antibodies. The pooled global prevalence of biopsy-confirmed celiac disease was 0.7% in 138,792 individuals. That means that numerous people with celiac disease potentially remain undiagnosed.
    Rates of celiac disease were 0.4% in South America, 0.5% in Africa and North America, 0.6% in Asia, and 0.8% in Europe and Oceania; the prevalence was 0.6% in female vs 0.4% males. Celiac disease was significantly more common in children than adults.
    This systematic review and meta-analysis showed celiac disease to be reported worldwide. Blood test data shows celiac disease rate of 1.4%, while biopsy data shows 0.7%. The prevalence of celiac disease varies with sex, age, and location. 
    This review demonstrates a need for more comprehensive population-based studies of celiac disease in numerous countries.  The 1.4% rate indicates that there are 91.2 million people worldwide with celiac disease, and 3.9 million are in the U.S.A.

    Celiac.com 06/15/2018 - There seems to be widespread agreement in the published medical research reports that stuttering is driven by abnormalities in the brain. Sometimes these are the result of brain injuries resulting from a stroke. Other types of brain injuries can also result in stuttering. Patients with Parkinson’s disease who were treated with stimulation of the subthalamic nucleus, an area of the brain that regulates some motor functions, experienced a return or worsening of stuttering that improved when the stimulation was turned off (1). Similarly, stroke has also been reported in association with acquired stuttering (2). While there are some reports of psychological mechanisms underlying stuttering, a majority of reports seem to favor altered brain morphology and/or function as the root of stuttering (3). Reports of structural differences between the brain hemispheres that are absent in those who do not stutter are also common (4). About 5% of children stutter, beginning sometime around age 3, during the phase of speech acquisition. However, about 75% of these cases resolve without intervention, before reaching their teens (5). Some cases of aphasia, a loss of speech production or understanding, have been reported in association with damage or changes to one or more of the language centers of the brain (6). Stuttering may sometimes arise from changes or damage to these same language centers (7). Thus, many stutterers have abnormalities in the same regions of the brain similar to those seen in aphasia.
    So how, you may ask, is all this related to gluten? As a starting point, one report from the medical literature identifies a patient who developed aphasia after admission for severe diarrhea. By the time celiac disease was diagnosed, he had completely lost his faculty of speech. However, his speech and normal bowel function gradually returned after beginning a gluten free diet (8). This finding was so controversial at the time of publication (1988) that the authors chose to remain anonymous. Nonetheless, it is a valuable clue that suggests gluten as a factor in compromised speech production. At about the same time (late 1980’s) reports of connections between untreated celiac disease and seizures/epilepsy were emerging in the medical literature (9).
    With the advent of the Internet a whole new field of anecdotal information was emerging, connecting a variety of neurological symptoms to celiac disease. While many medical practitioners and researchers were casting aspersions on these assertions, a select few chose to explore such claims using scientific research designs and methods. While connections between stuttering and gluten consumption seem to have been overlooked by the medical research community, there is a rich literature on the Internet that cries out for more structured investigation of this connection. Conversely, perhaps a publication bias of the peer review process excludes work that explores this connection.
    Whatever the reason that stuttering has not been reported in the medical literature in association with gluten ingestion, a number of personal disclosures and comments suggesting a connection between gluten and stuttering can be found on the Internet. Abid Hussain, in an article about food allergy and stuttering said: “The most common food allergy prevalent in stutterers is that of gluten which has been found to aggravate the stutter” (10). Similarly, Craig Forsythe posted an article that includes five cases of self-reporting individuals who believe that their stuttering is or was connected to gluten, one of whom also experiences stuttering from foods containing yeast (11). The same site contains one report of a stutterer who has had no relief despite following a gluten free diet for 20 years (11). Another stutterer, Jay88, reports the complete disappearance of her/his stammer on a gluten free diet (12). Doubtless there are many more such anecdotes to be found on the Internet* but we have to question them, exercising more skepticism than we might when reading similar claims in a peer reviewed scientific or medical journal.
    There are many reports in such journals connecting brain and neurological ailments with gluten, so it is not much of a stretch, on that basis alone, to suspect that stuttering may be a symptom of the gluten syndrome. Rodney Ford has even characterized celiac disease as an ailment that may begin through gluten-induced neurological damage (13) and Marios Hadjivassiliou and his group of neurologists and neurological investigators have devoted considerable time and effort to research that reveals gluten as an important factor in a majority of neurological diseases of unknown origin (14) which, as I have pointed out previously, includes most neurological ailments.
    My own experience with stuttering is limited. I stuttered as a child when I became nervous, upset, or self-conscious. Although I have been gluten free for many years, I haven’t noticed any impact on my inclination to stutter when upset. I don’t know if they are related, but I have also had challenges with speaking when distressed and I have noticed a substantial improvement in this area since removing gluten from my diet. Nonetheless, I have long wondered if there is a connection between gluten consumption and stuttering. Having done the research for this article, I would now encourage stutterers to try a gluten free diet for six months to see if it will reduce or eliminate their stutter. Meanwhile, I hope that some investigator out there will research this matter, publish her findings, and start the ball rolling toward getting some definitive answers to this question.

    Celiac.com 06/14/2018 - Refractory celiac disease type II (RCDII) is a rare complication of celiac disease that has high death rates. To diagnose RCDII, doctors identify a clonal population of phenotypically aberrant intraepithelial lymphocytes (IELs). 
    However, researchers really don’t have much data regarding the frequency and significance of clonal T cell receptor (TCR) gene rearrangements (TCR-GRs) in small bowel (SB) biopsies of patients without RCDII. Such data could provide useful comparison information for patients with RCDII, among other things.
    To that end, a research team recently set out to try to get some information about the frequency and importance of clonal T cell receptor (TCR) gene rearrangements (TCR-GRs) in small bowel (SB) biopsies of patients without RCDII. The research team included Shafinaz Hussein, Tatyana Gindin, Stephen M Lagana, Carolina Arguelles-Grande, Suneeta Krishnareddy, Bachir Alobeid, Suzanne K Lewis, Mahesh M Mansukhani, Peter H R Green, and Govind Bhagat.
    They are variously affiliated with the Department of Pathology and Cell Biology, and the Department of Medicine at the Celiac Disease Center, New York Presbyterian Hospital/Columbia University Medical Center, New York, USA. Their team analyzed results of TCR-GR analyses performed on SB biopsies at our institution over a 3-year period, which were obtained from eight active celiac disease, 172 celiac disease on gluten-free diet, 33 RCDI, and three RCDII patients and 14 patients without celiac disease. 
    Clonal TCR-GRs are not infrequent in cases lacking features of RCDII, while PCPs are frequent in all disease phases. TCR-GR results should be assessed in conjunction with immunophenotypic, histological and clinical findings for appropriate diagnosis and classification of RCD.
    The team divided the TCR-GR patterns into clonal, polyclonal and prominent clonal peaks (PCPs), and correlated these patterns with clinical and pathological features. In all, they detected clonal TCR-GR products in biopsies from 67% of patients with RCDII, 17% of patients with RCDI and 6% of patients with gluten-free diet. They found PCPs in all disease phases, but saw no significant difference in the TCR-GR patterns between the non-RCDII disease categories (p=0.39). 
    They also noted a higher frequency of surface CD3(−) IELs in cases with clonal TCR-GR, but the PCP pattern showed no associations with any clinical or pathological feature. 
    Repeat biopsy showed that the clonal or PCP pattern persisted for up to 2 years with no evidence of RCDII. The study indicates that better understanding of clonal T cell receptor gene rearrangements may help researchers improve refractory celiac diagnosis.
