Filter by:- To search the effects of montelukast on the airway inflammation including FEV1%, FEV1%/FVC, the provocholine® (methacoline chloride powder for inhalation) challenge tests, the leukotriene levels in the exhaled breath condensate in asthmatic children with and without food allergy aged 6-18 years old. - To define the patient groups with good response to montelukast and to define the parameters which predict the good response.
- Hypothesis 1: Food allergies are associated with poor growth which can be corrected with nutrition intervention. - More than 10% of children with multiple food allergies will have a weight-for-age z-score less than - 2 at diagnosis. The z-score is a measure of the distance from the mean value, or 50th percentile on the growth chart. A z-score of less than - 2 indicates that the child is underweight. - Growth parameters of children with multiple food allergies will improve after intervention by a team that includes a dietitian and an allergist. - Hypothesis 2: Food allergies are associated with low micronutrient intake which can be corrected with nutrition intervention. o More than 30% of children with multiple food allergies will consume less than 67% of the Dietary Reference Intake for at least one macronutrient or micronutrient at diagnosis. - Macronutrient and micronutrient intake will increase after intervention by a team that includes a dietitian and an allergist. • Hypothesis 3: Food allergies are related to behavioral feeding problems which can be corrected with nutrition intervention. - At least 25% of children with multiple food allergies will have behavioral feeding problems at diagnosis. - Prevalence of behavioral feeding problems will decrease after nutrition intervention.
Immediate food allergy is , sometimes , a life threatening situation . Diagnosis is done by skin prick test with commercial extracts. Nevertheless, some of the extracts are not optimal and reproduce false negative results (no allergy) in patients with history highly suggestive of allergic reaction. The aim of this study is to compare the reproducibility of different commercial extracts and raw food in patients with convincing history of acute allergic symptoms related to food .
The purpose of this study is to analyze the expression and activity of inhibitory molecules on eosinophils obtained from allergic subjects.
The purpose of this study is 1. To validate in french quality of life questionnaires for food allergic children 2. To evaluate if the quality of life of food allergic french speaking children aged 0-12 years is affected by their condition 3. To validate a didactic game for food allergic children
The goal of this study will be to increase the reaction threshold (desensitization) of peanut allergic children using peanut sublingual immunotherapy and to determine if the nonreactive state of the immune system persists after treatment has been discontinued (tolerance).
ITN049AD (LEAP-On) Study is a continuation of the ITN032AD LEAP Study (NCT00329784). Peanut Allergy, a recognized public health concern, is a common and potentially life-threatening food allergy for which there is no treatment. ITN032AD (LEAP) Study evaluated whether early exposure to peanut promotes tolerance and provides protection from developing peanut allergy in children who are allergic to eggs or who have severe eczema. ITN049AD (LEAP-On) Study will evaluate persistent tolerance to peanut by assessing the effect of twelve months of cessation of peanut consumption in LEAP Study participants who consumed peanut and those who avoided peanut over the previous five years.
The investigators plan to launch a Specific Oral Tolerance Induction (SOTI) pilot study in order to assess the efficacy and the safety of hypoallergenic (H.A.) wheat cereals, for children with allergy to wheat. The study has the potential to offer a desensitization treatment option for children allergic to wheat. The investigators hypothesize that H.A. wheat cereals have similar efficacy with less side effects than native wheat cereals.
