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.

    Mass screening studies among the general population for celiac disease show a prevalence of approximately 0.5-1.0% in adults and in children. Yet, despite the growing numbers of newly diagnosed celiac disease patients, most cases still remain undiagnosed and therefore, untreated. In part, the masses of misdiagnosed or undiagnosed  celiac disease  patients are a result of the variety of disguises  celiac disease can have. Celiac disease can manifest into a multitude of symptoms including, but by no means exclusive to, malabsorption syndrome, diarrhea, anemia, infertility and osteoporosis.

    A team of researchers recently compared the technical performance and accuracy (sensitivity and specificity) of commercial IgG anti-DGP assays from Euroimmun, Inova, Phadia and The Binding Site against other serologic assays for celiac disease, such as 3IgA and 2IgG anti-tTG assays, 1IgA and 1IgG anti-gliadin assay, 1IgA anti-DGP assay.

    Many people are confused about which tests provide the most accurate results for a celiac diagnosis. In a recent study by a team at the Department of Gastroenternology and Internal Medicine, St. Orsola-Malpigihi Hospital, University of Bologna, Bologna, Italy, researchers evaluated  current testing methods, and made some conclusions about celiac testing that may shed light on the subject for those of us overwhelmed by current conflicting information.

    A team of researchers recently set out to study the viability of confirming histological evidence of villous atrophy in real time, during upper gastrointestinal endoscopy, in live duodenal mucosa of patients with celiac disease, using endocytoscopy, a novel diagnostic technique allowing in vivo real-time visualization of mucosa under 450x magnification.

    A team of researchers recently set out to compare levels of glutamic acid decarboxylase antibody (anti-GAD), islet cell antibody (ICA), thyroperoxidase antibody (anti-TPO), thyroglobulin antibody (anti-TG), antinuclear antibodies (FANA), antibodies to double-stranded DNA (anti-ds DNA), antibody to Sjögren syndrome A antigen (anti-SSA), antibody to Sjögren syndrome B antigen (anti-SSB), Smith antibody (anti-Sm), smooth muscle antibodies (ASMA), and antimitochondrial antibody liver-kidney microsome (AMA-LKM) in patients with celiac disease against healthy control subjects, and autoimmune hypothyroid patients.

    The problem with current diagnosis criteria for celiac disease is that it takes a certain degree of damage to intestinal villi in order to get a formal diagnosis. Since celiac disease with villi damage are just one manifestation of a much broader and more widespread problem--gluten sensitivity...

    The practice of using antibody testing to diagnose celiac disease has led to an explosion in the number of cases detected among children, coupled with a rise in median age at diagnosis, a new study suggests.

    A team of researchers recently set out to assess the prevalence of variable biopsy findings and duodenal bulb involvement in children with celiac disease, as well as its association with clinical parameters.

    Could unknown benefits from one of the oldest parasites of the human digestive tract hold the key to cure for celiac disease? Australian scientists think so. Encouraged by successful treatments of Crohn's and ulcerative colitis by American researchers using a pig whipworm (Trichuris sues), a team of Australian researchers is recruiting volunteers with celiac disease for trials using human hookworm (Necator americanus).

    Although doctors view celiac disease mainly as a gastrointestinal disease, it is now known to have widespread systemic manifestations.A team of researchers recently set out to define the nature and role of systemic cytokine levels in the pathophysiology of celiac disease.

    A team of researchers recently used transcription factor analysis to examine whether celiac patients up-regulate T-bet and pSTAT1 expressions in peripheral blood and whether such up-regulation may be associated with celiac disease activity.

    A team of researchers recently set out to develop specific and sensitive immunoassays that can reliably detect celiac disease. In this case, they developed immunoassays for the detection of IgG and IgA antibodies to gliadin using synthetic peptides. Their results show that Celiac G+ ELISA provides better sensitivity and better specificity compared with other available synthetic gliadin peptide immunoassays.

    The standard method of measuring successful observance of a gluten-free diet in patients with celiac disease is through a dietary interview performed by health professional. However, there is currently have no simple, objective method for conducting such a dietary interview.

    A team of Maltese researchers, led by genetics specialist Christian Scerri, has discovered that a previously unassociated gene contributes to the development of celiac disease. The association of the gene, a variant of a gene called CD59, is the result of three years of research at a University of Malta lab.

    A team of researchers led by Michelle M. Pietzak, M.D., of the University of Southern California Keck School of Medicine in Los Angeles, recently conducted a large-scale study to identify HLA-DQ haplotypes most connected with increased risk of celiac disease.

    Antibodies to deamidated gliadin offer a promising new tool in the diagnosis of celiac disease. A team of researchers recently set out of examine serodiagnosis of childhood celiac disease assay of antibodies against deamidated gliadin.

    Are non-inflammatory gluten peptide analogs effective as biomarkers for celiac disease? Recent research indicates that they just might represent an effective new tool in the management of celiac disease.

    While the use of anti-tTG antibodies is common practice in the diagnosis of celiac disease, their value in long-term follow-up remains controversial. A team of researchers recently set out to assess the value of anti-tTG antibodies in long-term follow-up.

    Accurate blood tests have revolutionized celiac disease diagnosis. Recently, researchers K.E. Evans, A.R. Malloy, and D.A. Gorard set out to review requests for celiac blood testing at a district general hospital laboratory over a decade, to measure the volume of requests, identify their source of referral, and assess positivity rates, along with subsequent rates of duodenal biopsy and histological confirmation.

    Specialty pharmaceutical and diagnostic company, Prometheus Laboratories Inc., announced results from two recent studies concerning the use of serologic testing to predict inflammatory bowel disease (IBD).
