Filter by:To determine the allergenic potential in humans, we will conduct a three-stage clinical trial. In the first group, 20 healthy volunteers will be involved. All volunteers will be examined by an allergy specialist before enrolment to the study. After receiving informed consent, all volunteers will undergo an allergy skin test to the study seaweed proteins as well as to common allergens. Participants with a skin test showing sensitization will be excluded. Volunteers will be fed by 5 gram of the study seaweed 2 times a week, under supervision, for 6 weeks. After 6 weeks of feeding, skin tests will be repeated. All participants, will undergo an open oral food challenge after one month of avoidance of the study seaweed protein. Uneventful food challenge will rule out food allergy in a specific volunteer. Second, the extension clinical phase will be conducted with 100 healthy volunteers. The inclusion, exclusion and study design will be similar to the pilot study. The third phase will be conducted in a group of high-risk patients aimed to find the frequency of allergy to the study seaweed in high risk patients. Study population: 20 volunteers with high risk to seaweed food allergy. Inclusion criteria: Adults (>18 years old, males and females) with at least one of the following: Active atopic dermatitis or fish or sea food allergy. Study design will be similar to the pilot study.
At present there is no cure for food allergy. People with a food allergy need to avoid the food they are allergic to in order to stay safe, but we know that accidental exposure is common. Researchers have begun to look at the effectiveness of 'oral immunotherapy' as a treatment for food allergy but results have been mixed. This study is a randomized controlled trial to evaluate the effectiveness of Fish Immunotherapy (FOIT), with codfish as the primary focus, in inducing tolerance in children with fish allergy compared with Placebo. Children will take increasing doses of codfish protein until a total of 12 months treatment is completed. Children will be tested for fish allergy at the start of the study, at the end of fish treatment T1 (12 months) and T2 (8 weeks) after treatment.
At present there is no cure for food allergy. People with a food allergy need to avoid the food they are allergic to in order to stay safe. However we know that accidental exposure is common. Researchers have begun to look at the effectiveness of 'oral immunotherapy' as a treatment for food allergy but results have been mixed. This study is a randomized controlled trial to evaluate the effectiveness of Probiotic and Peanut Oral Immunotherapy (PPOIT) in inducing tolerance in children with peanut allergy compared with Oral Immunotherapy (OIT) alone and with Placebo. Children will take increasing doses of peanut protein and a set amount of probiotic until a total of 18 months treatment is completed. Children will be tested for peanut allergy at the start of the study, at the end of PPOIT treatment T1 (18 months) and T2 (8 weeks) and T3 (1year) after treatment.
Digital technology is essential in the field of health, via connected objects, the medical Internet or even telemedicine; and the info-communication practices (ways of getting information and communicating) of the actors go through digital devices. In addition, at present, the mass of activity documents to be managed in healthcare establishments and an abundant supply of documentary resources in health, available on the Internet, lead to infobesity, information pollution, and work overload. These phenomena lead to an increase in the time spent searching for relevant information and even to the burnout of healthcare professionals. A contextualization of the information communication systems through which the practices of health professionals pass therefore seems necessary so that the tools for managing, extracting and organizing knowledge can support these actors in their work. In the field of allergies, there are many players, and the information that is useful to them is abundant and heterogeneous. This study is based on the hypothesis that a knowledge organization model, developed from existing practices, could make it possible to obtain satisfactory results when searching for information, and be integrated into the daily practices of actors by linking up with other already existing systems and tools.
Early and regular ingestion of the common allergens, peanut and egg has been shown to be an effective allergy prevention strategy. It is not clear whether this is also true of tree nut allergy. Current practice in many Australian allergy clinics for children with peanut allergy (high risk of tree nut allergy), is to advise families to introduce each individual tree nut into their child's diet via a cautious home introduction protocol without prior allergy testing (screening). The safety and effectiveness of an early and regular ingestion strategy for the prevention of tree nut allergy has not been formally evaluated and it is known that around a third of children with peanut allergy develop one or more other nut allergies. This trial is a 2-armed, open-label, randomized, controlled trial (RCT) to assess the safety and efficacy of a supervised hospital based multi-tree nut (almond, cashew, hazelnut and walnut) oral food challenge (OFC) + then home introduction of the remaining tree nuts versus standard care (home introduction of all 8 tree nuts) in infants with peanut allergy to reduce the risk of developing tree nut allergy.
In this study, fecal and urine samples will be collected from children diagnosed with : - IgE mediated cow's milk allergy, - suspected of a cow's milk allergy, but with negative diagnosis - IgE mediated food allergy other than cow's milk - healthy brothers and sisters of the first three groups A subset of patients with IgE-mediated cow's milk allergy will be asked to provide a urine and fecal sample yearly for prognostic purposes. The samples will be analyzed using a technique called metabolomics to identify biomarker candidates with diagnostic and/or prognostic potential. Additionally, microbiome analysis will be performed to map the microbiome of all groups.
This is an observational cohort study of 221 breast-feeding mother-infant dyads delivered at term. The goal of the study is to investigate whether levels of immune-related microRNAs (miRNAs) in maternal breast milk (MBM) influence child atopy risk in the first 12 months, defined as atopic dermatitis, wheezing, or food allergy. Infant exposure to individual miRNA components will be quantified at 0, 4, and 16-weeks after delivery using high throughput RNA sequencing of MBM samples and detailed dietary logs employing the Infant Feeding Practices (IFP) survey. The relationship of individual miRNA exposures (parts per million) and presence/absence of atopy in the 48 weeks after delivery will be assessed, while controlling for environmental exposures (National Survey of Lead hazards and Allergens in Housing), maternal diet, and genetic predisposition. Potential transfer of MBM miRNAs to the infant oropharynx and subsequent impact on immune reactivity will also be explored through RNA sequencing of infant saliva and quantification of cytokine profiles.
This study is a multi-center, randomized, double-blind, placebo-controlled study in participants 1 to less than 56 years of age who are allergic to peanut and at least two other foods (including milk, egg, wheat, cashew, hazelnut, or walnut). While each participant may be allergic to more than two other foods, the primary endpoint/outcome in this study will only be assessed in peanut and two other foods for each participant. The primary objective of the study is to compare the ability to consume foods without dose-limiting symptoms during a double-blind placebo-controlled food challenge (DBPCFC), after treatment with either omalizumab or placebo for omalizumab.
Oral immunotherapy (OIT) is a food allergy treatment where small amounts of the food a child is allergic to is eaten and gradually increased over time with the aim to be able to eat a certain amount of the allergen without experiencing an allergic reaction. While this process works in many children there are concerns about safety, feasibility and drop-outs and how to adapt protocols for multiple allergies. Many OIT trials have targeted approximately 4000mg of single food/day. In these trials up to 40% drop-out. There is evidence much lower doses can have beneficial effects. The investigators will evaluate if low doses of foods can allow for OIT to multiple foods. This approach may have efficacy against accidental exposure and be able to demonstrate immune changes. This approach may have a low burden of treatment and a low rate of allergic reactions and
The study determines how a 6 months oral immunotherapy (OIT) program with hen's egg (HE) effects cellular and humoral immune responses in 50 children with HE allergy. Clinical data, transcriptomics and epigenetics are combined and analyzed by advanced system biology methods. This study will provide better understanding of the effects and mechanisms of OIT.
