Gluten Induces Subtle Histological Changes in Duodenal Mucosa of Patients with Non-Coeliac Gluten Sensitivity : A Multicentre Study
2022
Background: Histological changes induced by gluten in the duodenal mucosa of patients with non-coeliac gluten sensitivity (NCGS) are poorly defined. \ud \ud \ud \ud Objectives: To evaluate the structural and inflammatory features of NCGS compared to controls and coeliac disease (CeD) with milder enteropathy (Marsh I-II). \ud \ud \ud \ud Methods: Well-oriented biopsies of 262 control cases with normal gastroscopy and histologic findings, 261 CeD, and 175 NCGS biopsies from 9 contributing countries were examined. Villus height (VH, in μm), crypt depth (CrD, in μm), villus-to-crypt ratios (VCR), IELs (intraepithelial lymphocytes/100 enterocytes), and other relevant histological, serologic, and…

T helper cell polarisation in coeliac disease: any (T-)bet ?
2004
Recent data strongly support the view that coeliac disease is a Th1 mediated inflammatory disease as both interferon γ production and T-bet levels in gut infiltrating cells are upregulated The puzzling observation on high interferon γ (IFN-γ) but low interleukin (IL)-12 levels in coeliac disease (CD) has resulted in questions about the underlying principles of T helper cell polarisation. In this issue of G ut ,1 the molecular basis of T helper cell polarisation in CD has been illuminated by the finding that T-bet, the master transcription factor of T helper cell type 1 (Th1) cells, is upregulated in this disease [see page 1090] . The past decade has witnessed a dramatic improvement in our p…

Fast blue B functionalized silica-polymer composite to evaluate 3,5-dihy-droxyhydrocinnamic acid as biomarker of gluten intake
2021
Celiac disease is an immune-mediated systemic disorder elicited by gluten and related prolamines in genetically susceptible individuals. The current treatment is a strict and lifelong gluten-free diet. However, compliance with the gluten-free diet is not always adequate and many food products contain low concentrations of gluten. The determination of dietary transgressions is a challenge for patients, physicians and dietitians. Alkylresorcinols (AR) have been proposed as sensitive and specific biomarkers of gluten consumption. In this work silica-polymer composites doped with fast blue B reagent (FB) have been used to estimate alkylresorcinols in biological samples. The proposed colorimetri…
Refractory coeliac disease: one step closer to the origin of aberrant lymphocytes.
2012
Aberrant intraepithelial lymphocytes (IELs) are the key feature of refractory coeliac disease type II (RCDII), but the cellular origin of these aberrant IELs remains unclear. In a recent paper Schmitz et al 1 further explored previously characterised aberrant IEL cell lines from four patients with RCDII by using a broad spectrum of cell specific markers, RNA array and immunological techniques, to compare these cell lines to IELs from the fetal intestine, the intestine of children and adults and the thymus. IELs are a heterogeneous population of lymphocytes with innate and adaptive features that inhabit the small and large intestine. IELs are important for the maintenance of tolerance to com…

Vaccination Status and Attitudes towards Vaccines in a Cohort of Patients with Celiac Disease.
2022
(1) Background: The identification of vaccination status and attitudes towards vaccines among celiac disease (CD) patients is of great importance, but it has not yet been investigated. The aim of this study was to investigate coverage against vaccine-preventable diseases (VPDs), attitudes towards vaccinations, and its determinants among CD patients. (2) Methods: An anonymous web-based validated questionnaire was sent to a mailing list of CD adult patients. Patients were asked to self-report their previous vaccinations and attitudes towards vaccinations, which were defined as positive, negative, and partially positive/negative. The influencing factors towards vaccinations were investigated, …
Epidemiology and pathogenesis of celiac disease and non-celiac gluten (wheat) sensitivity
2021
Abstract While in the past, celiac disease (CD) was considered the only clinical entity caused by the ingestion of gluten-containing grains, now there is evidence that a spectrum of gluten-related disorders, including also wheat allergy and non-celiac gluten (wheat) sensitivity (NCGS/NCWS), exists. The prevalence of gluten-related disorders is rising, and increasing numbers of individuals are empirically trying a gluten-free diet for a variety of signs and symptoms. CD is a gluten-induced immune-mediated enteropathy characterized by a specific genetic genotype [human leukocyte antigen (HLA)-DQ2 and HLA-DQ8 genes] and autoantibodies (antitissue transglutaminase and antiendomysial). NCGS/NCWS…
