Abstract
Inflammatory processes affecting nasal and bronchial mucosa are
similar in nature. Flares of allergic rhinitis may precipitate additional
asthma attacks and aggravate the underlying asthma symptoms. Allergic
rhinitis is regarded as a risk factor for the development of asthma,
especially in the presence of bronchial hyperresponsiveness.
Patients with underlying allergic rhinitis are three times more likely
to develop asthma when compared with normal subjects. The presence of
bronchial inflammation in non-asthmatic patients with seasonal allergic
rhinitis is well established.
We therefore conducted a study on 60 children to examine whether
those with allergic rhinitis without known underlying asthma have
impaired spirometry. We compared them with those having allergic rhinitis
and asthma, also with others having asthma only. The effect of treatment
on spirometric parameters was shown after 3 months.
