Filter by:This study evaluates the effect of a multicomponent intervention applied to restaurant staff about training and nutritional quality of menu improvement, in order to promote a healthy diet and a better management of allergies and intolerances addressed to each family member satisfying the customers with specific needs (allergies and intolerances of food).
DAOsin is a food supplement for special medical purpose for the treatment of food intolerance provoked by histamine intake. In this uncontrolled, interventional pilot study the effect of an oral diamine oxidase substitution (DAOsin) on the reduced endogenous diamine oxidase activity in histamine intolerant patients will be examined. Patients with a low endogenous diamine oxidase activity (below 10 Units/ml) take DAOsin for one month 3 times a day. During this month the diamine oxidase activity is tested biweekly. Afterwards a follow up period of one month without taking DAOsin follows. Again the diamine oxidase activity is tested biweekly.
The primary objective is to obtain stool samples from subjects diagnosed with , and displaying signs and/or symptoms of IBD and/or IBS will be evaluated in this study. Eligible subjects require a diagnostic colonoscopy with possible biopsy and clinical evaluation.
A PROSPECTIVE, double blind, placebo-controlled trial
Background: The immediate endoscopic identification and diagnosis of intraepithelial structures and immediate and delayed reactions to allergens in the mucosal surface of the gut are unmet goals in the diagnosis and management of subjects with food intolerances, who are negative to all available tests. Endomicroscopy may be helpful to further visualize and characterize unmasked small bowel reactions to foods, which has not been described before. Confocal laser endomicroscopy provides confocal microscopic imaging simultaneously to the macroscopic view ,which enables the examiner to see immediate reactions after exposure and it further allows capturing of fluid excreted by the gut for further analysis to understand the pathology behind this reaction further. N=50 patients with unexplained bloating and diarrhoea with suspicion of food intolerance and negative testing with routine methods. Patients with Lactose intolerance n=10 patients to compare results. Patients with Fructose intolerance n=10 patients to compare results. Volunteers with Barrett's esophagus who need evaluation for possible dysplasia in the Barrett's mucosa with confocal endomicrosopy but no symptoms of bloating and abdominal pain (n=10) to serve as healthy controls for allergy testing. Methods: The primary objective is to investigate whether endomicroscopy will allow the detection of an allergic reaction of the gut after exposure of the 5 major allergens in the following way: After standard gastroscopy with the endomicroscope including evaluation of the surface of the upper gastrointestinal tract, i.v. injection of Fluorescein, then initial visualisation of the duodenal surface including count of initial lymphocytes/mononuclear cells in the lamina propria: Allergen 1 (milk), allergen 2 (wheat), allergen 3 (soya),allergen 4 (apple), allergen 5 (yeast). The primary endpoint is the visible marked increase of lymphocytes and mononuclear cells in the lamina propria of the duodenum, representing an acute reaction to one of the allergens sprayed to its surface through the endoscope channel.
The purpose of this clinical trial is to evaluate the effect of a new infant starter formula with added prebiotics (GOS) and with a fat blend rich in beta-palmitate.
