Improving Diagnosis of Legume Allergy in Children

Study Purpose

In France, almost 15% of serious food allergies in children are caused by legumes, especially peanuts. Other legumes like soy, lentils, peas, lupin, chickpeas, beans, and fenugreek can also cause allergic reactions. But here's the problem: only peanuts, soy, and lupin are required to be clearly labeled on food packaging in the European Union. This makes it hard for families to know when other legumes-like peas or fenugreek-are hidden in processed foods. Avoiding all these legumes is hard-especially since many of them are used in processed foods and not always listed on the label. Right now, detailed allergy tests to evaluate the probability of allergy diagnosis are only available for peanuts and soy, and not for other legumes. LACID study has been created to find and study the proteins in lupin, fenugreek, and peas that may cause allergies and developp better allergy tests for these legumes-possibly as part of a diagnostic tool that can give clear results using just a blood sample. The goal is to help doctors and families better understand which legumes a child really needs to avoid-and which ones are actually safe to eat.

Recruitment Criteria

Accepts Healthy Volunteers

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

No
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.

Observational
Eligible Ages N/A - 18 Years

Trial Details

Trial ID:

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.

NCT06995950
Phase

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.

Additional Details

In France, almost 15% of serious food allergies in children are caused by legumes, especially peanuts. Other legumes like soy, lentils, peas, lupin, chickpeas, beans, and fenugreek can also cause allergic reactions. But here's the problem: only peanuts, soy, and lupin are required to be clearly labeled on food packaging in the European Union. This makes it hard for families to know when other legumes-like peas or fenugreek-are hidden in processed foods. At the same time, legumes are being used more and more. They are healthy, rich in protein, and better for the environment. In France, a 2019 law (called EGALIM) requires at least one vegetarian meal per week in schools, and these meals often use legumes to replace meat. To make them more appealing to kids, legumes are turned into foods that look familiar-like veggie nuggets or burgers. As a result, children are eating more legumes, often without knowing it. Children who are allergic to peanuts are often also sensitised to other legumes. This is because the proteins in different legumes can be similar. But being "sensitised" doesn't mean a child will have a real allergic reaction when eating that food. Previously, a retrospective study conducted in Nancy, France, looked at nearly 200 children allergic to peanuts. In this study, 2 out of 3 children were sensitised to at least one other legume, 1 out of 5 was truly allergic to another legume and allergy was confirmed in 16% of cases for fenugreek, 56% for lupin, and 45% for peas. Avoiding all these legumes is hard-especially since many of them are used in processed foods and not always listed on the label. Lupin can be hidden in pastries, fenugreek is found in spice mixes and even some cheeses or medicines and peas are used in vegetarian dishes like veggie steaks or nuggets. This makes everyday life stressful for allergic children and their families. Right now, the only sure way to know if a child is allergic to a food is to do a carefully supervised food oral challenge at the hospital. But scientists are trying to find easier, safer ways to diagnose legume allergies-so that children don't have to avoid foods unnecessarily. So far, detailed allergy tests are available for peanuts and soy, but not for other legumes. LACID study has been created to find and study the proteins in lupin, fenugreek, and peas that may cause allergies and developp better allergy tests for these legumes-possibly as part of a diagnostic tool that can give clear results using just a blood sample. The goal is to help doctors and families better understand which legumes a child really needs to avoid-and which ones are actually safe to eat.
