Characteristic and Evolution of an Atypical IgE-mediated Cow Milk Allergy Form With Hands and Feet Angio-oedema

Study Purpose

Cow milk allergy is one of the most frequent food allergy among children. Cow milk protein's avoidance is needed until spontaneous recovery during the two first years of life. A atypical clinical form with angio-oedema of hands and feet which is associated with high rate of lactoserum's IgE might be a hope of an earlier recovery.

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 - 17 Years
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

- Patients with a concordant history of IgE-mediated CMA (skin reaction within the next hours of cow milk proteins intake, regression of symptoms with avoidance of cow milk, +/- recurrence of identical symptoms when readministration) - Patients with documented positive awareness markers (skin test and/or specific IgE > 0,1 kilo units of allergen-specific IgE per liter (kUA/l )) - Patients who have had a specific IgE assay at T0 (at diagnosis) and T1 (recheck 4 to 7 months after the reaction) - Age under 6 month at the time of the first CMA reaction.

- Patient followed at the pediatric allergology consultation at the Pediatric Hospitals of Nice.

Exclusion Criteria:

- patients without IgE specific performed in the first month after the reaction.

- patients who have had only 1 documented specific IgE test

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.	NCT04318483
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

Cow Milk allergy is one of the most frequent pediatric food allergy and occurs during the first months of life. It is due to an inappropriate reaction of immune system against the human body. Its treatment is the avoidance of the cow milk proteins. Its spontaneous recovery occurs mostly during the first years of life with the decreasing of the specific IgE and the clinical tolerance to cow milk proteins. Two shorts cas reports (3 and 5 patients) have described a clinical form of IgE-mediated cow milk allergy with angio-oedema of hands and feet. This clinical form is associated with more increasing of specific IgE against lactoserum proteins than caseine's. However it has been showed that casein is a marker of cow milk allergy persistence. It might be possible that this atypical form of cow milk allergy progresses favorably towards a restoration of tolerance earlier than the clinical form without angio-oedema of the extremities
