Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • kinetics of specific IgE

    kinetic is defined by dosage of specific IgE (cow milk, caseine, whey proteins) from diagnostic from control to 7 months after

    at inclusion

Secondary Outcomes (4)

  • comparison of specific IgE kinetics between case and control patient

    at inclusion

  • Clinical characteristics of allergic reaction

    at inclusion

  • Clinical characteristics of patients

    at inclusion

  • Age of clinical tolerance

    at inclusion

Eligibility Criteria

AgeUp to 17 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)
Sampling MethodNon-Probability Sample
Study Population

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

You may qualify if:

  • 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 ))
  • Patient followed at the pediatric allergology consultation at the Pediatric Hospitals of Nice

You may not qualify if:

  • patients without IgE specific performed in the first month after the reaction
  • patients who have had only 1 documented specific IgE test
