[Allergic rhinitis in children].

Allergic rhinitis is the most prevalent form of chronic rhinitis in children. It is driven by allergic inflammation and is commonly associated with other atopic diseases such as asthma and atopic eczema. The main allergens are primarily aeroallergens: house dust mite, and tree, grass and weed pollen. It is, however, not exceptional to experience symptoms of allergic rhinoconjunctivitis in conjunction with food allergy and oral food allergy syndrome, especially in infants and toddlers. Allergic rhinitis is often associated with allergic asthma, either preceding it, or developing later and making it more difficult to treat. The mainstay of treatment is exposure prophylaxis, antihistamines, leukotriene antagonists and intranasal corticosteroids. Allergic rhinitis is one of the prime indications for specific allergen immunotherapy, which may have a preventive effect on the development of asthma. Allergic rhinitis associated with intermittent or mild persistent asthma may be a good indication for concomitant combination treatment with antihistamines and leukotriene antagonists. Intranasal corticosteroids should not be withheld in more severe forms. Shortterm (up to 3 months) use of intranasal corticosteroids has not been associated with any significant local or systemic side effects.
