Two-thirds of patients with allergic rhinitis may be at risk of becoming asthmatic

Allergic rhinitis (AR) may be considered a risk factor for the onset of asthma. Recently, it has been reported that forced expiratory flow between 25% and 75% of vital capacity (FEF(25-75) ) may predict a positive response to bronchodilation test in asthmatic children.

1,500 adult patients suffering from persistent AR were evaluated in this study from Italy.

63% of patients had reversibility to bronchodilation test and 18% had impaired FEF(25-75) values (lower than 65% of predicted).

This study highlights that about two-thirds of patients with persistent AR may be considered at risk of becoming asthmatic. Spirometry may allow the early detection of patients prone to develop asthma.
