Non-Celiac Wheat Sensitivity Diagnosed by Double-Blind Placebo-Controlled Challenge: Exploring a New Clinical Entity
Gluten Intolerance and Sensitivityin the Elderly.
2020
Celiac disease (CD) is a chronic, immune-mediated enteropathy in genetically predisposed individuals caused by the ingestion of gluten-containing cereals. CD is further characterized by variable clinical presentation, specific serum autoantibody response and a variable degree of damage in the small intestinal mucosa. HLA molecules DQ2 (90%–95%) and DQ8 (5%–10%) are associated with CD, and in the continued presence of gluten the disease is self-perpetuating. Regarding clinical presentation, CD patients may complain of not only gastrointestinal (GI) symptoms, but also extraintestinal symptoms, and most importantly they may often be asymptomatic (“silent” CD). In recent years, several reports …
Recent Advances in Biotechnological Methods for Wheat Gluten Immunotoxicity Abolishment – a Review
2021
Due to the increasing incidence of gluten intolerance, researchers are focusing on finding ways to eliminate immunotoxicity of wheat, this would allow the use of wheat products for gluten-intolerant consumers. The article reviews recent studies on biotechnological methods to eliminate and reduce the immunogenicity of wheat products. So far, many gluten removal methods have been proposed, but their efficacy levels were quite different. Enzymatic treatment of gluten fragments can be considered the simplest and non-invasive tool to eliminate the toxicity of gliadins and glutenins. For this purpose, various endogenous enzymes derived from cereals, and also those of bacterial, fungal, plant, and…

Duodenal and Rectal Mucosa Inflammation in Patients With Non-celiac Wheat Sensitivity
2019
Background & Aims: Studies of non-celiac gluten or wheat sensitivity (NCGWS) have increased but there are no biomarkers of this disorder. We aimed to evaluate histologic features of colon and rectal tissues from patients with NCGWS. Methods: We performed a prospective study of 78 patients (66 female; mean age, 36.4 years) diagnosed with NCGWS by double-blind wheat challenge at 2 tertiary care centers in Italy, from January 2015 through September 2016. Data were also collected from 55 patients wither either celiac disease or self-reported NCGWS but negative results from the wheat-challenge test (non-NCGWS controls). Duodenal and rectal biopsies were collected and analyzed by immunohistoc…
Nomenclature and diagnosis of gluten-related disorders: A position statement by the Italian Association of Hospital Gastroenterologists and Endoscopi…
2017
Abstract Background “Gluten-related disorders” is a term that encompasses different diseases induced by the ingestion of gluten-containing food. Because of their incidence the scientific community has been intensively studying them. Aim To support gastroenterologists with a correct nomenclature and diagnostic approach to gluten-related disorders in adulthood. Methods The Italian Association of Hospital Gastroenterologists and Endoscopists (AIGO) commissioned a panel of experts to prepare a position statement clarifying the nomenclature and diagnosis of gluten-related disorders, focusing on those of gastroenterological interest. Each member was assigned a task and levels of evidence/recommen…
Lead contamination affects the primary productivity traits, biosynthesis of macromolecules and distribution of metal in durum wheat (Triticumdurum L.)
2021
Highlights • The growth, biosynthesis of pigments and other macromolecules appeared to be strong predictors in appraisal of Pb tolerance/susceptibility in durum wheat. • Germplasm of CBD59, CBD63 and CBD66 can be exploited for future selection and breeding programs. • The bioaccumulation of metal in grains of some cultivars of durum wheat much below than permissible limits set by FAO/WHO is of great significance owing to its implications for food safety.
Hybrid QconCAT-Based Targeted Absolute and Data-Independent Acquisition-Based Label-Free Quantification Enables In-Depth Proteomic Characterization o…
2021
Wheat amylase/trypsin inhibitors (ATIs) have gained significant relevance as inducers of intestinal and extra-intestinal inflammation. In this study, we present a novel hybrid data-independent acquisition (DIA) liquid chromatography-mass spectrometry (LC-MS) approach, combining QconCAT technology with short microflow LC gradients and DIA and apply the method toward the quantitative proteome analysis of ATI extracts. The presented method is fast, robust, and reproducible and provides precise QconCAT-based absolute quantification of major ATI proteins while simultaneously quantifying the proteome by label-free quantification (LFQ). We analyzed extracts of 60 varieties of common wheat grown in…
