Filter by:For Patients diagnosed as cow milk protein allergy: Elimination of cow's milk products (CMPs) for 6 months. All infants were supplemented with Amino Acid-based Formula (AAF) (Neocate infant®/ Neocate junior®, Dannone Nutricia) for 6 months at start of elimination diet. For mixed milk fed infants (still receiving breast milk with the formula), mothers were encouraged to continue breast-feeding while avoiding all milk and milk products from their own diet. Intervention after completing 6 months of eliminating CMPs. The included patients were randomly assigned to one of (2 groups). 1. Group I (AAF group) n= 50 Infants in this group continued with Amino Acid-based Formula for another 6 months. 2. Group II (pHF group) n= 50 Infants in this group were shifted gradually to Partially-hydrolyzed whey formula (pHF) (Liptomil Plus HA infant formula. for another 6 months with continuation of elimination of cow's milk products. They were followed up for manifestations of intolerance to pHF. Infant who showed manifestations of intolerance were returned to AAF and continued for 6 months with AAF. Final step: Reintoduction of CMPs After 12 months of elimination of CMPs, evaluation of tolerance to whole CMPs was done by oral food challenge (OFC). For infants who were still non-tolerant to CMPs after 12 months of elimination were followed up and re-challenged after 6 months.
The evaluation of the quality of life (QOL) in food allergy (AA) is difficult due to the lack of a currently validated questionnaire. There are only a few tools available to assess the impact of nutritional care on the QOL of the allergic patient . Available questionnaires are poorly adapted to studies dealing with large cohorts where functionality and ease of use are determining factors. The aim of this work will be to develop and validate QOL questionnaires for AA, short and easy to use, also integrating the theme of collective catering in order to assess the evolution of QOL in patients with food allergy. The target population of the questionnaires will be: i) the parents of allergic children 0 to 17 years (15 questions) ii) allergic children aged 8 to 17 years (13 questions) iii) Adults over 18 (14 questions) After receiving an information note, eligible patients or their parents will complete the questionnaires. A total of 200 patients will be recruited for each questionnaire. A statistical evaluation will be carried out using 200 questionnaires for each targeted population in order to validate the psychometric properties of the questionnaire as well as investigate the degree of correlation between the scores of the mini-questionnaire and those obtained using the Europrevall reference questionnaire.
The purpose of this study is testing the use of Enhanced-Butanol purified-Food Allergy Herbal Formula-2 (E-B-FAHF-2) Chinese herbal therapy in combination with multi-food oral immunotherapy (OIT) and Xolair® (Omalizumab) to help children and adults who are allergic to foods be able to safely tolerate food allergens. Specifically in this protocol, the food allergens are milk, egg, peanut, almond, cashew, hazelnut, walnut, sesame, and/or wheat. Omalizumab is considered an investigational drug for the treatment of food allergies in children and adults. Investigational means it has not been approved by the Food and Drug Administration (FDA) for use in the U.S. The researchers hope to learn whether the addition of Chinese herbal therapy (E-B-FAHF-2) can improve the outcome of sustained unresponsiveness (which is the ability to consume a food allergen and pass an oral food challenge after being off treatment for 3 months) as compared to placebo (i.e. subjects with OIT/Omalizumab + herbal vs. OIT/Omalizumab + placebo), and will help adults and children be able to safely ingest the foods they are allergic to.
The investigators will conduct low-dose intranasal allergen challenges on children and young people with an indeterminate diagnosis of food allergy to cow's milk or peanut. Blood samples will also be taken, for conventional blood allergy diagnostics (allergy-specific Immunoglobulin E) and mast cell activation test (MAT). The data will be used to determine the diagnostic accuracy of two complementary, novel approaches to diagnose food allergy, in a representative clinical cohort.
The purpose of this study is to describe the symptoms and their evolution up to the age of 5 years in a population of newly diagnosed infants with a suspected or confirmed allergy to cow proteins, for whom the doctor prescribed the Pepticate® Syneo® replacement formula as soon as they were diagnosed. The Pepticate® Syneo® product is an advanced protein hydrolyzate, food type intended for special medical purposes. This is a product already available on the market.
IgE-mediated wheat allergy is a growing allergy problem in children, and affected children can predict with immediate-type allergic reactions to the extent of anaphylactic shock. Current diagnostic methods based on crude wheat extract are inaccurate and unreliable. Besides, these children are managed by a passive "wait-and-see" approach that reflect the natural history of wheat allergy. Nonetheless, a significant proportion of wheat-allergic children have persistent disease until school-age and adolescence. There is an unmet need for designing effective and safe immunotherapeutic strategy for wheat allergy. This study aims to investigate performance of allergy tests based on crude wheat and wheat allergens as measured using both quantitative and functional IgE-based assays for diagnosing IgE-mediated wheat allergy; and to compare efficacy and safety of different dosages of wheat oral immunotherapy (OIT) for treating these paediatric patients. For the initial part, this study will recruit children with immediate-onset adverse reactions after wheat ingestion for different allergy tests, with their wheat allergy ascertained by the gold-standard double-blind, placebo-controlled food challenge. The investigators will then recruit the wheat-allergic children into a randomized, double-blind, parallel-group clinical trial with low-dose and standard-dose wheat OIT for 12 months. The main outcomes include the diagnostic performance of different conventional and novel allergy tests for challenge-confirmed wheat allergy and the rates of desensitization and sustained unresponsiveness achieved by the two dosing regimens of wheat OIT.
Thresholds In food allergy evaluaTion And predictioN, a prospective, observational registry. The aim is to quantify food allergy thresholds in Canada and their clinical predictors.
The proposed research project will evaluate a novel behavioral intervention that promotes early adolescent food allergy self-management and adjustment through 1) food allergy education, 2) problem-solving, communication, assertiveness, and anxiety management skill building, and 3) peer support.
Infant food protein allergy is the most common allergic disease in children, which can lead to infantile-specific dermatitis, intestinal inflammation, and so on. Dietary avoidance is a common strategy for food protein allergy in infants and young children. However, the hidden etiology of food protein allergy or multiple food allergies often leads to poor efficacy. The aim of this study is to observe the clinical effectiveness of Bifidobacterium intervention on food allergy.
The goal of this single center retrospective cohort study with observational longitudinal follow up is to compare food - allergic children (egg, milk and peanut allergy) with children in control group (children without any food allergy). The main question[s] it aims to answer are: - If children with food allergy groups will have lower food intake od micronutrients? - If growth in children with food allergy is worse as in control group? - If they are more malnourished and in the food allergies group is more stunting than in the control group? - If children with milk allergy have lower intake of calcium in their diet and lower mineral bone density? Participants will be asked to do 3 day food diary and to have blood analysed (hemograme, complete blood count, serum iron status, serum protein). If there is a comparison group: Researchers will compare milk, egg and peanut allergy group to the control group (peers without food allergy) to see if the food allergy affects growth, macronutrient, micronutrient intake.
