The purpose of this study was to determine if asthma with and without rhinitis represent distinct forms of disease. A prospective cross-sectional study. Healthy controls, participants with asthma without rhinitis, and participants with both asthma and rhinitis We compared lung function and airway inflammation between the three groups of participants. We recruited 32 participants: 12 normals, 8 asthmatics without, and 12 with rhinitis. Compared to asthmatics with rhinitis, asthmatics without rhinitis had more severe airflow limitation (FEV1/FVC 60.6 [IQR 22.8] versus 74.8 % [IQR 7.8] and fewer induced sputum eosinophils (2.8 [IQR 5.8] and 9.6 [IQR 23.8], respectively). Sputum interleukin 6 correlated inversely with lung function measured by post-bronchodilator FEV1 in the study cohort (Spearman correlation coefficient −0.55, p<0.01). Asthmatics without rhinitis tend to have lower lung function and less eosinophilic inflammation in the lung. This study suggests that asthmatics without rhinitis represent a distinct phenotype of asthma in which low lung function is dissociated from eosinophilic cellular inflammation.
