We investigated the effect of intranasal, inhaled corticosteroid or the combination of both in patients with both pollen- induced rhinitis and asthma.

Background: Sublingual immunotherapy (SLIT) is a clinically effective treatment in both pollen and house dust mite- induced rhinitis and asthma.

Allergic diseases such as allergen- induced rhinitis represent an inflammatory reaction that is characterized by the chemotaxis and activation of various cell populations.
