• Resumen

  • Objective Allergic rhinitis (AR), non-allergic rhinitis (NAR), chronic rhinosinusitis with nasal polyps (CRSwNP), and chronic rhinosinusitis without nasal polyps (CRSsNP) occur frequently in asthmatic patients. We evaluated nasal symptoms and nasal endoscopic findings in patients with asthma and correlated them to asthma severity.

    Methods Subjects (n = 150) with asthma completed questionnaires designed to provide information related to asthma and nasal disease. Patients were divided into four groups based on asthma severity. Pulmonary function tests, skin-prick tests (SPTs) and nasal endoscopy were performed on every patient. Clinical findings were compared in asthma patients by rhinologists.

    Results The total incidence of AR, NAR, CRSwNP and CRSsNP in these patients with asthma was 76%. By using Fisher's Exact Test, there was no statistical significance between asthma severity and the incidence of AR, NAR, CRSwNP and CRSsNP (P = 0.311). There was a significant difference in the total nasal symptoms score among subjects with different grades of asthma (P = 0.002). However, there were no significant differences in the total Lund�Kennedy endoscopic score (LKS) (P = 0.736). The nasal endoscopic scores were significantly correlated at a high degree with the nasal symptoms score (P = 0.000). A significant correlation was found between the nasal endoscopic score and the duration of asthma in the patients with different grades of asthma (P < 0.05).

    Conclusions The relationship between rhinitis and asthma is complex. Nasal airways should become part of standard clinical assessment and follow-up in patients with asthma.
