Confirmation of Etiologic Diagnosis in Children With House Dust Mite Allergy as an Essential Stage Before Allergen Specific Immunotherapy. A Review

Abstract

House dust mites are important cause for allergic rhinitis, and almost half of allergic rhinitis patients is sensitized to them. In patients with house dust mite allergy evidence of sensitivity can not be strictly achieved with medical history and patients complaints, since the cause-effect relationships are not obvious. At the same time incomplete allergological examination can lead to an incorrect definition of the main relevant allergens, and expensive treatment may not give the desired result in this cases. The estimation of the allergens for allergenspecific immunotherapy should be based on the disease history, detection of offending allergens by means of allergological examination in vivo with skin tests, nasal or conjunctival provocational tests, and component diagnostics if necessary. This approach based on use of provocational tests as a part of allergological examination is considered to be one of the ways to personalized therapy.
