Celiac disease is a T cell-driven intolerance to wheat gluten. The gluten-derived T cell epitopes are proline-rich and thereby highly resistant to proteolytic degradation within the gastrointestinal tract. Oral supplementation with prolyl oligopeptidases has therefore been proposed as a potential therapeutic approach. The enzymes studied, however, have limitations as they are irreversibly inact...

We conducted online electronic searches (published manuscripts in English) of the Cochrane Library, pub med and manual searches of selected specialty journals to identify any pertinent literature. The search was conducted using the key words ‘celiac disease’, ‘gluten related disorder’, ‘non celiac gluten sensitivity’, ‘wheat allergy’, ‘gluten’, , ‘gluten free diet’. Studies not published in Eng...

Celiac Sprue is a multifactorial disease characterized by an intestinal inflammatory response to ingested gluten. Proteolytically resistant gluten peptides from wheat, rye, and barley persist in the intestinal lumen and elicit an immune response in genetically susceptible individuals. Here, we demonstrate the in vivo ability of a gluten-digesting protease ("glutenase") to accelerate the breakdo...

INTRODUCTION Celiac disease is a common autoimmune condition induced by dietary gluten in genetically susceptible individuals. So far, the only available treatment for the disorder is a lifelong strict gluten-free diet, because of which small intestinal histological changes recover and symptoms disappear. However, gluten-free dieting is restrictive, and nutritionally less than optimal, and glut...

Strict criteria for the diagnosis of temporary gluten intolerance are formulated in the light of the case of an 8-week-old infant with severe diarrhoea and failure to thrive, who recovered on an elimination diet that was gluten-free. 8 weeks later an oral challenge with 2.5 g twice daily of powdered gluten for one day produced diarrhoea, weight loss, and impaired xylose absorption. Gluten was s...

Non-celiac gluten sensitivity is defined as a reaction to gluten in persons with a confirmed absence of allergic or autoimmune mechanisms after appropriate laboratory testing. Symptoms resemble those of irritable bowel syndrome (IBS), and may overlap with celiac disease or true wheat allergy. In a research environment, symptoms of non-celiac gluten sensitivity resolve when dietary modifications...

BACKGROUND A non-human primate (NHP) model of gluten sensitivity was employed to study the gene perturbations associated with dietary gluten changes in small intestinal tissues from gluten-sensitive rhesus macaques (Macaca mulatta). METHODOLOGY Stages of remission and relapse were accomplished in gluten-sensitive animals by administration of gluten-free (GFD) and gluten-containing (GD) diets,...

BACKGROUND The European Society for Paediatric Gastroenterology, Hepatology and Nutrition recommended in 2008, based on observational data, to avoid both early (<4 months) and late (≥7 months) introduction of gluten and to introduce gluten while the infant is still being breast-fed. New evidence prompted ESPGHAN to revise these recommendations. OBJECTIVE To provide updated recommendations reg...

An evaluation of the effect of 1 year of a gluten-free diet was performed in patients with irritable bowel syndrome and fibromyalgia syndrome displaying lymphocytic enteritis. Gluten withdrawal produced a slight but significant improvement of the functional symptoms, suggesting that gluten might be partly responsible for this clinical picture. This hypothesis should be confirmed by a double-bli...

Gluten-related diseases were recently classified into three groups according to their physiopathological mechanisms: autoimmunity (celiac disease, dermatitis herpetiformis, gluten ataxia), allergy (wheat allergyrespiratory, alimentary, contact urticary and WDEIA) and no-autoimmune no-allergic (gluten sensitivity)(30). Dermatitis herpetiformis (DH) is an autoimmune blistering cutaneous disease t...
