Paranasal computed tomography results in asthma patients: Association between sinus sites and allergen types
Chronic rhinosinusitis (CRS) is a common comorbidity of asthma. The aim of this study was to investigate the relationships between the presence of rhinosinusitis, sinus site involvement, and total computed tomography (CT) sinus scores and the presence of allergy, allergen type, and severity of disease. Asthma patients (128 subjects), consisting of 57 allergic and 71 nonallergic patients, were included in the study. Presence of rhinosinusitis and sinus scores were evaluated by CT. CRS was determined in 45 (78.9%) allergic asthma patients and 44 (62.0%) nonallergic asthma patients (p < 0.05). Ethmoid sinus involvement was higher among allergic asthma patients compared with nonallergic patients (68.4% versus 43.7%; p = 0.005). House-dust mite allergy (71.4% versus 46.5%; p = 0.008) and pollen allergy (73.5% versus 47.9%; p = 0.01) showed positive correlations with ethmoid sinus involvement. No correlation was found between severity of disease and mean total CT sinus scores (p > 0.05). The present study has shown the prevalence of chronic sinusitis to be higher in patients with allergic asthma, particularly in patients allergic to house-dust mites and pollens, with no correlation between severity of disease and presence of CRS. Investigating chronic sinusitis together with allergen sensitivity early in asthma diagnosis may contribute positively to patient treatment.
