RESUMO

There is increasing evidence for a close link between the upper and the lower respiratory tracts and the fact that rhinitis has an important impact on asthma. Several clinical and experimental observations suggest a similar immunopathology between the upper and lower airways in allergic subjects. The common inflammatory process that develops in the respiratory tract explains some of the complex interactions among different clinical diseases such as rhinitis, sinusitis, asthma, bronchial hyperresponsiveness and viral infections. There are also non-inflammatory mechanisms that may contribute to the link between rhinitis and asthma. Moreover, the outcomes of various pharmacological treatments of rhinitis have recently provided further support for the hypothesis of the united airways. We discuss some of the recent observations on the nose-lung interaction and some of the novel therapeutic approaches used to treat rhinitis and asthma that arise from this.
