[Questionnaire for determining relationship between nasal and asthma symptoms].
BACKGROUND
The interaction between allergic rhinitis and bronchial asthma is well known. However, there is little epidemiological data on the relationship between nasal diseases and asthma, especially in Japan.


METHODS
We administered a questionnaire to 126 patients to examine the frequency of associations between nasal and asthma symptoms in patients with both nasal disease and asthma. We also investigated in which type of patients the asthma symptoms were affected by changes in nasal symptoms.


RESULTS
Thirty-eight patients (30%) were aware that their asthma was worsened by exacerbated nasal disease, and nasal treatment improved asthma in 28 patients (22%). The influence of changes in nasal symptoms on asthma symptoms was stronger in patients lacking good asthma control. The relationship between nasal and asthma symptoms tended to be stronger in patients with sinusitis.


CONCLUSIONS
About 30% of patients with nasal disease and asthma reported an association between their nasal and asthma symptoms. Nasal treatment is considered to be important for asthma control, especially in patients with asthma symptoms. These results suggested the important role of comprehensive allergy care in controlling both nasal disease and asthma.
