[Can allergy be prevented in children? Environmental intervention. CON: environmental intervention is not effective].
Genetic and environmental background of allergic disease has been suggested the option of allergy prevention by allergen avoidance. For many years this environmental manipulation has been commonly recommended as primary prevention, but it was not effective which was proved by general increasing trend in allergy prevalence. Prospective observation of birth cohort combined with well controlled intervention didn't confirm the usefulness of such intervention. Allergen elimination as an element of secondary and tertiary prevetion could be effective if it leads to true reduction of allegen concentration which seems very difficult. Allergen elimination using currently available methods is very expensive with little benefit. During last few years new opposite option of allergy prevention it means tolerance induction has been proposed. Till now traditional approach to allergy prevention is worldwide recommended.
