Gluten sensitivity

H F Dale, J G Hatlebakk, N Hovdenak, S O Ystad, G A Lied
BACKGROUND: Non-coeliac gluten-sensitivity (NCGS) has been proposed as a new entity with unknown prevalence and mechanisms, and there is a need for a standardized procedure to confirm the diagnosis. The objective of this study was to characterize the response to an oral gluten-challenge in patients with a symptom-relief when following a gluten free-diet (GFD). METHODS: Twenty patients (14F/6M, age range: 21-62 years) with suspected NCGS, without coeliac disease and wheat-allergy, were included while on a gluten-free diet...

Gluten-related disorders are a complex group of diseases that involve the activation of the immune system triggered by the ingestion of gluten. Among these, celiac disease, with a prevalence of 1 %, is the most investigated, but recently, a new pathology, named nonceliac gluten sensitivity, was reported with a general prevalence of 7 %. Finally, there other less-prevalent gluten-related diseases such as wheat allergy, gluten ataxia, and dermatitis herpetiformis (with an overall prevalence of less than 0...

Alpha-gliadin is a highly immunogenic protein from wheat, which is associated with many human diseases, like celiac disease and non-celiac gluten sensitivity. Because of that, gliadin solution is subject to intense biomedical research. However, the physicochemical nature of the employed gliadin solution at physiological pH is not understood. Herein, we present a supramolecular evaluation of the alpha-gliadin protein in water at pH 3.0 by dynamic light scattering (DLS), cryo-transmission electron microscopy (cryo-TEM) and small-angle-...

BACKGROUND: Wheat-dependent, exercise-induced anaphylaxis (WDEIA) is a severe form of allergy in which exercise is being considered as mandatory. The diagnosis is often complex and the clinical reproducibility low. OBJECTIVE: The aims of this study were to establish a standardized challenge method for the diagnosis of WDEIA and to investigate whether exercise is an essential trigger factor or alternatively an augmentation factor able to lower threshold and increase severity...

The aim of the present study was to determine if the enzyme Aspergillus niger prolyl endoprotease (ANPEP), which degrades the immunogenic proline-rich residues in gluten peptides, can be used in the development of new wheat products, suitable for gluten-sensitive (GS) individuals. We have carried out a double-blind, randomised, cross-over trial with two groups of adults; subjects, self-reporting benefits of adopting a gluten-free or low-gluten diet (GS, n 16) and a control non-GS group (n 12). For the trial, volunteers consumed four wheat breads: normal bread, bread treated with 0·8 or 1 % ANPEP and low-protein bread made from biscuit flour...

In the reported case, a 41-year-old Italian man came to the clinician's observation reporting cramps, bloating and watery diarrhoea a few days after drinking water indicated as unpotable from a fountain in a farm area. The medical suspicion was directed at both gluten intolerance and enteric infection, eventually of waterborne origin. Gluten intolerance was investigated by intestinal biopsy and excluded, while stool analyses ruled out infective bacteriological or viral agents and parasites. Subsequently, a persistent eosinophilia was revealed and a parasitological analysis was again suggested, planning for a more sensitive molecular method...

OBJECTIVES: The wide spectrum of clinical symptoms of celiac disease (CD) is partly due to the malnourished state caused by the malabsorption of micro- and macronutrients. It has been suggested that fertility problems and obstetric complications may be a consequence of the endocrine disorders caused by selective nutrient deficiencies. The same selective nutrient deficiencies as in CD could be a reason for fertility problems in non-celiac gluten sensitivity (NCGS). The aim of this study was to investigate the effect of nutrient deficiencies in CD and NCGS on fertility problems...

BACKGROUND: Coeliac disease is one of most prevalent autoimmune illnesses encountered in general practice, and general practitioners have a central role in its diagnosis and follow-up. Key challenges are improving its poor rate of detection, distinguishing it from 'gluten sensitivity', and monitoring and optimising treatment to enhance long‑term outcomes. OBJECTIVE: The objective of this article is to review the evidence-based use of serology, histology and genetic testing in the diagnosis and follow-up care of adults and children with coeliac disease...

Hashimoto's thyroiditis (HT) affects more than 14 million individuals in the United States, most of them women. Thyroid replacement therapy has long been the foundation of medical treatment for HT; however, recent research supports a role for nutritional approaches. This case report describes the management of a 34-y-old female with HT who declined thyroid replacement therapy and was successfully managed for a period of 5 mo. The patient was advised to follow a phytonutrient rich diet (eg, berries); avoid sensitive foods (gluten and soy); and consume quality fats, fermented foods, and filtered water...

BACKGROUND: Paroxysmal gluten-sensitive dyskinesia (PGSD) in border terriers (BTs) results from an immunologic response directed against transglutaminase (TG)2 and gliadin. Recent evidence suggests that PGSD is only one aspect of a range of possible manifestations of gluten sensitivity in the breed. HYPOTHESIS/OBJECTIVES: Gluten sensitivity in BTs is a heterogeneous disease process with a diverse clinical spectrum; to characterize the phenotype of PGSD using TG2 and gliadin autoantibodies as diagnostic markers...

Celiac disease is an autoimmune disorder due to the inflammatory response to gluten in genetically predisposed individuals. It causes an enteropathy associated with several nutritional complications. Strict compliance to a gluten-free diet (GFD) is the current primary therapy. Nonceliac gluten sensitivity (NCGS) is a condition in which gluten ingestion leads to systemic symptoms but is not associated with small bowel atrophy or abnormal celiac serologies. A GFD heals celiac disease enteropathy and improves symptoms in NCGS...

OBJECTIVES: Non-celiac gluten sensitivity (NCGS) is characterized by intestinal and extra-intestinal symptoms that are related to the ingestion of gluten in subjects who are not affected by either celiac disease (CD) or wheat allergy (WA). In this multicenter study, we aim for the first time to evaluate the prevalence of NCGS in pediatric subjects with chronic functional gastrointestinal symptoms associated with gluten ingestion using a double-blind placebo-controlled (DBPC) gluten challenge with crossover...

Introduction: The course of psoriasis relies on a variety of metabolic and immunological parameters. Identification of underlying pro-inflammatory conditions and their control is desired for optimal management. Background: Increased prevalence of serum markers for celiac disease has been reported among patients with psoriasis. The likelihood of occult celiac disease in a subpopulation of patients has been postulated and gluten-free diets have been reported to be effective...

Gluten-related disorders (GRDs) are gradually emerging as epidemiologically relevant diseases, with a global prevalence estimated to be approximately 5% in the population. Conditions related to gluten ingestion include celiac disease (CD), wheat allergy (WA), and nonceliac gluten sensitivity (NCGS). Although mediated by different pathogenic pathways, these 3 conditions share similar clinical manifestations and can present a difficult differential diagnosis. The gluten challenge (GC) is an important diagnostic tool for GRDs, but there is great variability in regards to deciding which patients should be challenged, what amount of gluten should be used, what the GC duration should be, when and where the GC should occur, and, sometimes, why to conduct a GC...

Progesterone is a steroid hormone secreted from the corpus luteum (CL), which is responsible for establishment and maintenance of pregnancy. Early embryonic mortality often occurs due to inadequate regulation of uterine prostaglandin (PG) F2alpha secretion, leading to decrease in progesterone and loss of pregnancy. The objective of the current study was to determine the effects of fish meal supplementation on luteal sensitivity to intrauterine infusions of PGF2alpha. Non-lactating beef cows received corn gluten meal or fish meal supplementation for 60-days...

Nonceliac gluten sensitivity (NCGS) is a gluten-related gastrointestinal disorder distinct from celiac disease (CD) and gluten allergy that is not easy to diagnose due to the lack of biomarkers. It is characterized by intestinal symptoms and extraintestinal manifestations with the consumption of gluten-containing foods. In contrast to CD, NCGS patients do not present a genetic predisposition or intestinal villi atrophy. Recent studies question the proinflammatory triggering activity of α-gliadin fraction contained in wheat, since it has been demonstrated that the amylase-trypsin inhibitors (ATIs) exert a strong activating effect on the innate immune response...

BACKGROUND & AIMS: Information about the clinical outcome of patients with non-celiac wheat sensitivity (NCWS) treated with gluten-free diet (GFD) derive from studies assessing the symptom response in the first few weeks of treatment. We aimed to evaluate the clinical response to the GFD and the quality of life (QoL) of NCWS patients in the long term. METHODS: Forty-four NCWS (diagnosed according to the Salerno criteria) participated in the study. Participants rated their symptoms according to a 0-10 scale patients and filled in a QoL questionnaire (CDQ) before the beginning of the GFD and during a follow-up evaluation performed after at least one year...

Coeliac disease (CD) is an autoimmune disease, characterised by a permanent sensitivity to gluten. It is being progressively recognised as a multisystemic disease, with multiple extraintestinal manifestations. Skin conditions (eg, dermatitis herpetiformis) are an example of its manifestations; however, its underlying mechanisms are still not well understood. This article presents three cases of uncommon skin conditions in patients with a history of CD. Two of them concern linear IgA bullous dermatosis and erythema nodosum, which have been described in the literature as having potential associations with CD, though only a few cases were reported...
