Abstract

Abstract
Background : the link between allergic rhinitis(AR) and asthma has been confirmed. AR is a risk factor for the onset of asthma . Spirometry is a noninvasive method to evaluate lower respiratory system function in AR patients.
The aim of the study: to evaluate spirometric lung function and response to post- bronchodilatation test in patient with AR.
Methods: This prospective cross sectional study carried out on 100 patients with persistent AR. Spirometry ,post- bronchdilatation test, serum total IgE and eosinophils in blood and sputum were performed for all patients.
Results: Our results reconfirming the concept of "a single air way with a single disease". In our study the patients with persistent AR were have impaired spirometric parameters.
Conclusion: Our study confirming the predictive value of forced expiratory flow at 25% and 75% (FEF 25-75) as a marker of early bronchial involvement of small air way disease (SAD) in AR and also confirm the link between upper and lower respiratory system.
