Accidental Reactions in Peanut/Tree Nut Allergic Children

Study Purpose

Food allergy is an immune reaction, triggered by food protein allergens, of varying severity, from mild local reaction to life threatening anaphylaxis and fatalities. Peanut is a plant from the botanical family of the Fabaceae, more commonly known as legumes. The prevalence of peanut and tree nut allergy is increasing. In France (ELFE cohort), it is estimated to 0.93%. The tree nuts include mainly almond, hazelnut, pistachio, cashew nut, walnut, pecan nut and Brazil nut. Allergy's prevalence is estimated to 0.54% in children up to 5.5 years. Peanut allergy is a main cause of anaphylaxis and deaths due to food allergy. Recurrence of food allergy is a main concern. The risk has been estimated to 10% per year for peanut. In France, Data in real-life on the rate of recurrence of allergic reactions and anaphylaxis to peanut/tree-nut as well as risk factors, are lacking. The objective of this study is to assess the frequency of allergic reaction to peanut and tree-nuts, to describe the reactions' characteristics and risk factors.

Recruitment Criteria

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
