A few years ago, a study examined the results of tests performed routinely in asthmatic children over 5 years. The top ten of this study was in order: the two main families of mites of house dust (Dermatophagoides ptéronussinus and Dermatophagoides farinae), pollens from grasses (cocksfoot, phéole, ivraie), cats, cockroaches, or cockroaches, pollens bétulacées (alder, birch, charm, hazelnut), wheat, two air molds (Alternaria, Cladosporium) and rabbit hair. Positive tests for animals other than cat food and came away after the “winners”.

Children food allergies is increasing, but remains lower than allergy to dust mites, which has become a real public health problem. It should be remembered that 60 to 80% of children with asthma are sensitive to dust mites in house dust. Asthma affects, depending on age, 11 to 14% of children and adolescents french. In France, 7 to 9% of children are allergic to dust mites!

In the same study, one is surprised to find little testing positive for the dog, because this allergy is not exceptional. This phenomenon is explained technically. The allergen extracts used in tests for dogs are manufactured by laboratories. The product used for the test did not cover all species of dogs. The presence in the classification of wheat does not mean that children react to the consumption of wheat. This positive test is mainly due to cross-react with pollen. Other allergens very real, but more rare

Obviously these 10 allergens, the most common in children, do not summarize all allergies in children. The study looked at children whose dominant event was asthma. A similar study conducted among children with eczema have found more food allergens. Other allergens are encountered less frequently. The change of lifestyle leads to emergence of new allergies, including pets. Allergy to insects and especially wasps is uncommon in children and is uniquely responsible for respiratory signs. Allergy to drugs is a reality but it is much rarer than previously thought in children.
