Nasal Airway Resistance and Latent Lower Airway Involvement in Allergic Rhinitis.

Conclusion: Significantly greater proportion of patients with moderate-severe and persistent allergic rhinitis had elevated nasal airway resistance values. 72% patients with allergic rhinitis had lower airway involvement despite having no symptoms of asthma, prevalence being greater in patients with severe and persistent disease. Proportion of patients with lower airway hyper-responsiveness is significantly higher among patients with raised nasal airway resistance as determined by rhinomanometry. This study thus concludes that measurement of nasal airway resistance determined by active anterior rhinomanometry is a good objective tool to measure severity of nasal obstruction in allergic rhinitis with good correlation with the ARIA clinical severity grade .It may also be a promising tool to identify allergic rhinitis patients who are at a higher risk of having latent lower airway involvement.
