To the Editor:The observations of Ciprandi and Cirillo1 on the presence of
subclinical airway obstruction in patients without asthma with al-lergic rhinitis are appreciated. Airflow obstruction in patients withallergic rhinitis was first reported more than 30 years ago.2,3 How-ever, relatively small numbers of subjects were included in theseearlier studies. Ciprandi and Cirillo1 report on 4782 subjects withallergic rhinitis without asthma symptoms and with a normalFEV1. Twenty-three percent of these patients had a forced expira-tory flow between 25% and 75% of vital capacity (FEF25-75)<_65% predicted. They indicate that an FEV1 <_85% predictedwas 90.7% sensitive and 87.6% specific for the identification ofindividuals with FEF25-75 <_65% predicted.
It would be important to know whether those with an FEF25-75<_65% predicted have reversible airflow obstruction as shown byan improvement in FEV1 in response to a bronchodilator. Previ-ous publications partially address this question. Fairshter et al3 re-port that the rhinitis group demonstrated a significant increase inmaximal expiratory flow at 50% of vital capacity, FEV1, andforced vital capacity in response to isoproterenol inhalation. Sve-nonius et al4 also demonstrated a significant increase in maximalexpiratory flow at 25% of vital capacity (V9max25) in their allergicrhinitis group in response to an inhaled ß-adrenergic agonist (al-buterol). Because this information is presented as group results,we do not know whether increased flow rates in response to bron-chodilators in the allergic rhinitis group were the result of greaterresponses among individuals with FEF25-75 <_65% predicted thanamong those with a higher FEF25-75. This raises the question ofwhether the subset of patients with allergic rhinitis who have air-way hyperreactivity5-7 and reversible airflow obstruction in facthave asymptomatic asthma or whether there are critical physio-logic factors that protect these individuals from developing theasthmatic phenotype despite allergy and baseline airwaydysfunction.

We thank the authors of the published article on forcedexpiratory flow between 25% and 75% of vital capacity(FEF25-75) and bronchodilation response in children withasthma1 for their response.2 The data concerning the responseto the bronchodilation test are not available in our studybecause the Italian Navy Medical Corps states as rules forasthma diagnosis, in case of normal FEV1 values, thatmethacholine bronchial challenge must be performed toassess the possible presence and the degree of bronchialhyperreactivity. In this regard, our data showed that 36.7%of patients with impaired FEF25-75 values (such as <_65% ofpredicted) had severe bronchial hyperreactivity, whereasonly 7.3% of patients with normal FEF25-75 values had severebronchial hyperreactivity.
