Brachypodium distachyon, a small annual grass with seed storage globulins as primary protein reserves was used in our study to analyse the toxic nature of non-prolamin seed storage proteins related to celiac disease. The main storage proteins of B. distachyon are the 7S globulin type proteins and the 11S, 12S seed storage globulins similar to oat and rice. Immunoblot analyses using serum samples from celiac disease patients were carried out followed by the identification of immune-responsive proteins using mass spectrometry...

BACKGROUND: Celiac disease (CD) is a gluten-triggered autoimmune disorder of the small intestine. A lifelong gluten-free diet (GFD) is the only approved treatment; however, strict adherence is difficult and many suffer from inadvertent gluten exposure. Oral egg yolk anti-gliadin antibody (AGY) is a novel treatment to neutralize gluten and may improve the efficacy of the GFD. AIMS: To determine the safety, tolerability, and potential efficacy of AGY in patients with CD...

The association between pediatric celiac disease (CD) and atherosclerosis is unknown. Our aim was to investigate whether pediatric CD patients have an increased risk of atherosclerosis. We evaluated the premature atherosclerosis by pulse wave velocity (PWV) and carotid intima-media thickness (cIMT). A total of 37 CD patients (20 girls, mean age 13±3.3 years) and 36 healthy age and sex matched controls were enrolled. Mean duration of CD was 47.1±32.3 months and 40.5% of patients had positive tissue transglutaminase antibody (tTg) IgA...

BACKGROUND: The clinical manifestations of celiac disease (CD) have changed in the past decades. There are currently little data describing the initial clinical manifestations of CD in children in Iran. This study describes the initial presentation of children with suspected CD from a geographically defined region in Iran. METHOD: Medical records of children seen in 2007 - 2015 from Sistan and Baluchestan province, Iran, with suspected CD were reviewed. After obtaining TTG-IgA and IgA, subjects were divided into three groups according to presenting symptoms: GI, non-GI, and asymptomatic group...

BACKGROUND: Alopecia areata (AA) is a noncicatricial (nonscarring) alopecia. The association between AA and celiac disease (CD) is debatable. Several studies declare the relationship between AA and CD as measurement of celiac autoantibodies (anti-gliadin IgA and anti-gliadin IgG), but a few studies consider anti-tissue transglutaminase IgA. The aim of this study was to evaluate the frequency distribution of celiac autoantibodies (all of them) in patients with AA compared with controls...

BACKGROUND: Immunoglobulin A (IgA) antibodies to tissue transglutaminase (tTG) are the serologic test of choice for diagnosing celiac disease (CD). Our aim was to determine if elevated IgA anti-tTG were associated with increased mortality risk. METHODS: Stored serum samples of National Health and Nutrition Examination Survey (NHANES) III (1988-1992) were available for 6032 individuals aged 50 years old or above, which were screened for IgA anti-tTG, and if positive, for IgA endomysial antibodies...

Tissue transglutaminase 2 enzyme plays a diverse role in intracellular and extracellular functioning. Aberrant expression of anti-TG2 antibody has recently been proposed for extraintestinal identification of celiac disease (CeD), but its utility is questionable. To examine whether anti-TG2 immunohistochemical (IHC) staining can be of diagnostic value in identifying extraintestinal involvement in CeD, tissue blocks of patients with IgA nephropathies (IgAN), minimal change disease, membranous glomerulonephritis, membrano-proliferative glomerulonephritis, normal kidney, intestinal biopsies from CeD, tropical sprue, nonspecific duodenitis, and inflammatory bowel disease; liver biopsies from patients with chronic hepatitis B and C, acute liver failure (ALF), and CeD-associated liver diseases were retrieved and subjected to IHC staining for anti-tissue transglutaminase 2 enzyme...

OBJECTIVES: Celiac disease (CD) and irritable bowel syndrome (IBS) share similar symptoms, leading to confusion between the two and diagnostic delay. International guidelines recommend screening individuals with IBS for CD, via serological testing. However, studies published recently have cast doubt on the utility of this. We updated a previous meta-analysis examining this issue. METHODS: MEDLINE, EMBASE, and EMBASE Classic were searched through to May 2016. Eligible studies recruited adults with IBS according to symptom-based criteria, physician's opinion, or questionnaire data...

Celiac disease is an autoimmune, gastrointestinal disorder characterized by intolerance to the dietary grain protein gluten. An increased prevalence of celiac disease has been reported in Down syndrome and Turner syndrome, but there has been only few previous reports with respect to the association of celiac disease in Williams-Beuren syndrome. The aim of this study was to evaluate the frequency of celiac disease in our 24 Williams-Beuren syndrome patients. Gastrointestinal problems and celiac disease symptoms of patients were noted...

OBJECTIVES: Treatment for celiac disease (CD) is a lifelong strict gluten-free diet (GFD). Patients should be followed-up with dietary interviews and serology as CD markers to ensure adherence to the diet. However, none of these methods offer an accurate measure of dietary compliance. Our aim was to evaluate the measurement of gluten immunogenic peptides (GIP) in stools as a marker of GFD adherence in CD patients and compare it with traditional methods of GFD monitoring. METHODS: We performed a prospective, nonrandomized, multicenter study including 188 CD patients on GFD and 84 healthy controls...

Celiac disease (CD) is an autoimmune disease frequently associated with type 1 diabetes (T1D). The prevalence of CD in patients with T1D varies from 3 to 6%. The clinical manifestation of CD in patients with T1D is classified as asymptomatic in about half of cases. Our study aims to determine the frequency of anti-tissue transglutaminase autoantibodies (IgA-tTG) and anti-gliadin antibodies (AGA) in patients with type 1 diabetes in order to early recommend jejunal biopsy and establish a gluten-free diet before the onset of clinical signs and complications of celiac disease...

Microbial transglutaminase (mTg) is capable of cross-linking numerous molecules. It is a family member of human tissue transglutaminase (tTg), and is involved in CD. Despite declarations of the safety of mTg for industrial use, direct evidence for immunogenicity of the enzyme is lacking. The serological activity of mTg, tTg, gliadin complexed mTg (mTg neo-epitope) and gliadin complexed tTg (tTg neo-epitope) were studied in 95 pediatric celiac patients (CD), 99 normal children (NC), 79 normal adults (NA) and 45 children with nonspecific abdominal pain (AP)...
