Reply To the Editor: The observations of Ciprandi and Cirillo 1 on the presence of subclinical airway obstruction in patients without asthma with al- lergic rhinitis are appreciated. Airflow obstruction in patients with allergic rhinitis was first reported more than 30 years ago. 2,3 How- ever, relatively small numbers of subjects were included in these earlier studies. Ciprandi and Cirillo 1 report on 4782 subjects with allergic rhinitis without asthma symptoms and with a normal FEV 1 . Twenty-three percent of these patients had a forced expira- tory flow between 25% and 75% of vital capacity (FEF 25-75 ) < _65% predicted. They indicate that an FEV 1 < _85% predicted was 90.7% sensitive and 87.6% specific for the identification of individuals with FEF 25-75 < _65% predicted. It would be important to know whether those with an FEF 25-75 < _65% predicted have reversible airflow obstruction as shown by an improvement in FEV 1 in response to a bronchodilator. Previ- ous publications partially address this question. Fairshter et al 3 re- port that the rhinitis group demonstrated a significant increase in maximal expiratory flow at 50% of vital capacity, FEV 1 , and forced vital capacity in response to isoproterenol inhalation. Sve- nonius et al 4 also demonstrated a significant increase in maximal expiratory flow at 25% of vital capacity (V9 max 25) in their allergic rhinitis 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 greater responses among individuals with FEF 25-75 < _65% predicted than among those with a higher FEF 25-75 . This raises the question of whether the subset of patients with allergic rhinitis who have air- way hyperreactivity 5-7 and reversible airflow obstruction in fact have asymptomatic asthma or whether there are critical physio- logic factors that protect these individuals from developing the asthmatic phenotype despite allergy and baseline airway dysfunction.

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.
