[Rhinovirus and airway allergy].
Rhinoviruses cause the majority of common colds, which often provoke wheezing in patients with asthma. The precise mechanisms responsible for the rhinovirus infection-induced exacerbations of bronchial asthma remain uncertain.

Thus, it may affect the nasal airway patency, function and sinonasal-related quality of life. The aim of this study is to objectively and subjectively evaluate these effects. Methods: In this prospective study, 43 patients with pituitary adenoma who were c...
متن کاملMechanisms of the Development of Nasal Hyperreactivity in Nasal Allergy
Nasal hyperreactivity in nasal allergy conditions is closely related to allergic inflammation, particularly to infiltration by activated eosinophils in the nasal mucosa, observed 4 to 10 hours after a single antigenic challenge. Repeated antigenic challenge in subjects with nasal allergy enhanced nasal hyperreactivity. On the other hand, various therapies including topical steroids, immunothera...
متن کاملAirway allergy and viral infection.
There are complex interactions between airway allergy and viral infection. Available evidence suggests that viral respiratory infection can initiate, maintain and activate exacerbation of allergic conditions in respiratory tract. Innate and inflammatory responses to acute viral infection play important roles in its relationship to allergic reactions. On the other hand, biased immune responses t...
