Celiac Disease Diagnosis, Testing & Treatment (Gluten-Free Diet)

This category contains a comprehensive overview that covers the information on diagnosing and treating celiac disease, including the latest research on the various new tests/screening techniques.
Note: The only medically acceptable treatment for celiac disease is a 100% gluten-free diet for life.

    Villous atrophy may be present only in the duodenal bulb, so a biopsy of this region should always be including when diagnosing celiac disease.

    A team of researchers set out to assess the clinical, pathological and serological spectrum of celiac disease in a general population via prospective study (Kalixanda study).

    Adherence to biopsy guidelines recommended by the AGA in 2006 - that at least four samples be submitted - doubles the probability of a celiac diagnosis.

    New research on using HLA-DQ2-gliadin tetramer test to detect celiac disease.
    In an effort to improve diagnosis of celiac disease in patients already on a gluten-free diet, a team of researchers recently evaluated HLA-DQ2-gliadin tetramers for detection of gluten-specific T cells in peripheral blood and histological changes in the duodenum after a short gluten challenge as a diagnostic tool.

    Question:  Do I have to re-introduce gluten in order to have an accurate gluten sensitivity test done?  Answer: Yes and No.  If a person knows they are sensitive to gluten and have gone on a
     gluten-free diet, and want to know if they can have gluten again, then a challenge is in order (reintroduce gluten).

    Tina Turbin is an author, researcher, and gluten-free advocate.
    As an author, researcher, and gluten-free advocate, I work hard to raise awareness for celiac disease and gluten issues, particularly when it comes to increasing the diagnosis rate. Part and parcel of improving diagnosis is proper testing. Evidence is mounting that indicates that blood testing may not be the most effective way to test for celiac disease, and I would recommend that people who suspect they have celiac disease to check with their doctors about other testing options.

    New celiac saliva screening study in JPGN.
    Driven by the high prevalence of celiac disease, a team of researchers based in Italy to assess a new, noninvasive disease screening strategy that would allow them to make an early diagnosis of celiac disease in 6- to 8-year-old children.

    New American Journal of Gastroenterology paper examines celiac disease prevention measures.
    A team of researchers recently compiled an overview of prevention measures and exploratory pharmacological treatments of celiac disease. Maud Pinier, Gregor Fuhrmann, Elena Verdu and Jean-Christophe Leroux comprised the research team.

    Important new FDA approval of celiac disease testing.
    The US Food and Drug Administration (FDA) has given 510(k) clearance for the first two fully automated gliadin tests featuring deamidated peptides for celiac disease. That means U.S. doctors and patients looking for accurate early diagnosis of celiac disease now have a state of the art celiac disease assay with both a high level of sensitivity and specificity.

    Serological screening of healthy volunteers from around the world estimates that the prevalence for celiac disease is approximately 0.5%- 1% of the total population. However, a recent meta-analysis denotes that the actual ratio of known or undiagnosed celiac cases is closer to 1 in 7 people.

    Blood tests miss in some symptomatic kids.
    Properly diagnosing children with celiac disease in conditions where there may be environmental or other causes for classic celiac-associated symptoms, such as malnutrition, diarrhea, and failure to thrive, can present challenges to clinicians.

    Scientists have previously seen a nuclear fluorescence reactivity (NFR) pattern on monkey esophagus in sections which were exposed to celiac disease patients that were sera positive for anti-endomysium antibodies (EMA). Because of this prior knowledge, scientists created a new study to illustrate the NFR, to study  NFR positive results in connection with gluten withdrawal, and also to assess  the possible role if NFR in celiac disease follow-up's.

    A team of researchers evaluated the possibility of diagnosing celiac disease using quantitative analysis of videocapsule endoscopy images.

    In my work as an author, researcher, and gluten-free advocate, I strive to raise awareness for celiac disease and gluten intolerance because I know that with increased awareness will come more research, more proper diagnoses, and even improved treatment. Illustrating this, studies linking the onset of celiac disease to changes in microbes in the digestive tract are not only addressing the question of delayed onset, but they may lead to new research that could eventually result in a probiotic treatment for celiacs.

    A team of researchers recently set out to assess the positive predictive value of blood test screening for possible cases of celiac disease.

    A team of researchers recently conducted a systematic review of diagnostic testing for celiac disease among patients with abdominal symptoms.

    Tina Turbin describes the recent research indicating an association between irritable bowel syndrome and celiac disease. She describes celiac disease and gluten intolerance and the treatment, a gluten-free diet. She also sets down some of the benefits of increased celiac awareness and support for the gluten-free community.

    A team of researchers affiliated with the South-Eastern Norway Regional Health Authority and the University of Oslo is conducting a clinical trial to evaluate the use of HLA-DQ2-gliadin tetramer for diagnosing celiac disease. Their study will assess the use of HLA-DQ2-gliadin tetramer for staining gluten specific T cells to effectively diagnose uncertain celiac disease.

    New Blood Tests for Celiac Disease
    A research team set out to determine the usefulness of newer assays incorporating synthetic deamidated gliadin-related peptides (DGPs), or other TG isoenzymes as antigen, for detecting gluten sensitivity in IgA anti-tTG–seronegative patients.

    A group of clinicians recently set out to estimate the rate of mucosal recovery under a gluten-free diet in adult subjects with celiac disease, and to gauge the clinical prospects of ongoing mucosal damage in celiac patients following a gluten-free diet.
