RATIONALE: Epidemiological studies have shown that rhinitis and asthma coexist frequently. In addition, allergic rhinitis is an important risk factor for the development of asthma. This work was carried out to characterize the lung function of patients with allergic rhinitis without asthma.

METHODS: Descriptive cross-sectional study comprising 42 patients with a mean age of 26.5 years (range of 6 to 45 years) of which 59% were male, who were treated at the "General Calixto García" hospital in the period from April to August 2017. All patients underwent clinical history and spirometric with written informed consent. It was analyzed the relationship between the degree of involvement of lung function with the frequency and severity of allergic rhinitis and bronchodilator response, according to the classification of the ARIA modified guidelines.

RESULTS: 31% presented alterations in FEV1, predominating the male sex with 19.1%, 10 patients (23.8%) had persistent allergic rhinitis and 11 (26%) had good response after bronchodilators, reaching normal levels of FEV1.

CONCLUSIONS: In a high proportion of patients with persistent allergic rhinitis, there is involvement of lung function, reinforcing the concept of "a single respiratory tract with a single disease". It is necessary to evaluate lung function in patients with persistent allergic rhinitis.
