Factores ambientales de riesgo asociados a la enfermedad celiaca en población con susceptibilidad genética
2017
Introducción y justificación: La enfermedad celiaca (EC), es un trastorno sistémico permanente, provocado por una reacción inmunitaria activada por la ingestión de gluten y proteínas relacionadas, que se da en personas portadoras del HLA-DQ2 y/o DQ8. Este genotipo está ampliamente distribuido en población general, sin embargo solo 1/3 de los individuos genéticamente susceptibles acaba desarrollando una EC, lo que sugiere la necesidad de determinados factores ambientales cuyo papel sería fundamental en el desarrollo de la enfermedad. Numerosos estudios observacionales han sugerido que estos factores pueden ser la cantidad de gluten y el tipo de trigo (hexaploide o tetraploide) ingeridos en l…
Diagnosis of chronic anaemia in gastrointestinal disorders: a guideline by the Italian Association of Hospital Gastroenterologists and Endoscopists (…
2019
Anaemia is a common pathologic condition, present in almost 5% of the adult population. Iron deficiency is the most common cause; other mechanisms can be involved, making anaemia a multi-factorial disorder in most cases. Anaemia being a frequent manifestation in the diseases of the gastrointestinal tract, patients are often referred to gastroenterologists. Furthermore, upper and lower endoscopy and enteroscopy are pivotal to the diagnostic roadmap of anaemia. In spite of its relevance in the daily clinical practice, there is a limited number of gastroenterological guidelines dedicated to the diagnosis of anaemia. For this reason, the Italian Association of Hospital Gastroenterologists and E…
Evaluation of clinical dental variables to build classifiers to predict celiac disease
2008
Objective: The aim of this study was to evaluate the use of salivary variables to build statistical models for predicting celiac disease in symptomatic children. Materials and Methods: the study group consisted of 52 children with celiac disease diagnosed by bowel biopsy, grade III or IV (4 to 12 years old, both sexes) and 23 healthy children as a control group. A logistic regression model was applied to evaluate an individual’s belonging to one group or another. The performance of the model was evaluated by the value of area under the ROC curve. The salivary variables included in the model were the concentration of total proteins, calcium, Ca / P molar ratio, buffer capacity and salivary f…
Effects of Diets Supplemented with Medicinal Mushroom Myceliated Grains on Some Production, Health, and Oxidation Traits of Dairy Ewes
2019
The beneficial properties of mushrooms’ bioactive compounds indicate their potential for use as performance-enhancing natural additives for livestock animals. A study was undertaken to evaluate the effects of diets supplemented with mushroom myceliated grains (MMGs) fed to dairy ewes on intestinal parasite load, milk production, milk fatty acid (FA) composition, and cheese oxidative stability. During an 8-week experimental period, 21 lactating Valle del Belice ewes were divided into 3 groups named MMG20, MMG10, and MMG0. Ewes in each group were fed hay ad libitum and 1.3 kg/day/head of 1 of 3 concentrates with MMGs at 20% (MMG20), 10% (MMG10), or 0% (MMG0). The ewes fed MMG20 had comparable…
Effectiveness of the Influence of Selected Essential Oils on the Growth of Parasitic Fusarium Isolated from Wheat Kernels from Central Europe
2021
The aim of the study was to determine the effectiveness of selected seven commercial essential oils (EsO) (grapefruit, lemongrass, tea tree (TTO), thyme, verbena, cajeput, and Litsea cubeba) on isolates of common Central European parasitic fungal species of Fusarium obtained from infected wheat kernels, and to evaluate the oils as potential natural fungicides. The study was conducted in 2 stages. At each stage, the fungicidal activity of EsO (with concentrations of 0.025
Genome search in celiac disease.
1998
SummaryCeliac disease (CD), a malabsorption disorder of the small intestine, results from ingestion of gluten. The HLA risk factors involved in CD are well known but do not explain the entire genetic susceptibility. To determine the localization of other genetic risk factors, a systematic screening of the genome has been undertaken. The typing information of 281 markers on 110 affected sib pairs and their parents was used to test linkage. Systematic linkage analysis was first performed on 39 pairs in which both sibs had a symptomatic form of CD. Replication of the regions of interest was then carried out on 71 pairs in which one sib had a symptomatic form and the other a silent form of CD. …
Quality of Life in People with Coeliac Disease: Psychological and Socio- Economic Aspects.
2019
Background and Objective: Coeliac disease (CD) is a chronic autoimmune intestinal disorder characterized by intolerance to gluten, a protein contained in certain cereals. The main physiopathological basis of CD is the progressive destruction of intestinal villi caused by gluten ingestion by genetically-susceptible individuals. Patients who receive a diagnosis of CD must make significant changes to their daily habits and this can affect their quality of life. The objective of this review is to summarize the evidence regarding the economic, physical and social limitations which can affect the quality of life in patients with CD. Results: Different factors such as physical changes, psychologi…
Treatment of giardiasis reverses "active" coeliac disease to "latent" coeliac disease.
2001
In patients with coeliac disease, a regression of intestinal damage without a gluten-free diet is a very rare event. We describe a young child with diarrhoea, intestinal mucosa atrophy and positive serum anti-endomysial and anti-tissue transglutaminase (anti-tTG) antibodies during intestinal giardiasis infection. He showed normal intestinal mucosa architecture and negative anti-endomysial and anti-tTG antibodies after his giardiasis was cured, although he continued to assume a normal diet. Re-evaluations on a 6-monthly basis showed that he was symptom free, and all haemato-chemical parameters were within normal limits. Three years after the initial diagnosis, a third intestinal biopsy showe…
Wheat amylase trypsin inhibitors drive intestinal inflammation via activation of toll-like receptor 4
2012
Ingestion of wheat, barley, or rye triggers small intestinal inflammation in patients with celiac disease. Specifically, the storage proteins of these cereals (gluten) elicit an adaptive Th1-mediated immune response in individuals carrying HLA-DQ2 or HLA-DQ8 as major genetic predisposition. This well-defined role of adaptive immunity contrasts with an ill-defined component of innate immunity in celiac disease. We identify the α-amylase/trypsin inhibitors (ATIs) CM3 and 0.19, pest resistance molecules in wheat, as strong activators of innate immune responses in monocytes, macrophages, and dendritic cells. ATIs engage the TLR4–MD2–CD14 complex and lead to up-regulation of maturation markers a…
Effect of The Gluten-Free Diet on Quality of Life, Gastrointestinal Symptoms and Immune System in Patients with Fibromyalgia and Non-Celiac Wheat Sen…
2021
Fibromyalgia (FM) is a clinical syndrome characterized by chronic pain. FM patients complain hyperalgesia and allodynia and they are frequently affected by Non Celiac Wheat Sensitivity (NCWS), a condition where gastrointestinal and extraintestinal symptoms are triggered by gluten and/or wheat ingestion. The gluten-free diet (GFD) impact was evaluated on fibromyalgia-related and gastrointestinal symptoms, health-related quality of life and immune response of patients with both FM and NCWS in order to detect a possible pathogenetic role of wheat/gluten in the triggering of the inflammatory process. Peripheral blood from 8 FM patients, 10 FM and NCWS patients (FM+NCWS patients), 13 NCWS patien…
