Influence of asthma on quality of life and clinical characteristics of patients with nasal polyposis

Recent studies have evidenced that nasal polyposis (NP) may lead to significant limitations in physical, emotional and social aspects of life of the affected patients. The study is aimed to investigate the influence of asthma on quality of life (QoL), intensity of symptoms, endoscopic and computerized tomography (CT) sinus findings in patients with NP. The cross-sectional study included 88 adult patients with NP out of whom 35 (39.8 %) were asthmatic while 53 (60.2 %) were non-asthmatic. QoL is assessed based on Short Form-36 Health Survey (SF-36) questionnaire, while symptom intensity was presented using visual analogue scale (VAS). The objective finding is presented as endoscopic and CT score. Comparison of individual symptom intensity, total score and major symptom score failed to evidence any statistically significant difference between the groups. Minor symptom score which include intensity of headache, fetor ex ore, fatigue/malaise, dental pain, cough, pressure/fullness in the ears and fever was higher in the group with asthma (p < 0.05). Comparison of scores according to SF-36 domains, as well as summary scores for physical and mental health did not reveal statistically significant difference between the observed groups. Mean value of the endoscopic score in the group with asthma was 8.57 ± 2.22, being 8.38 ± 1.93 in the group without asthma (p > 0.05). Mean value of the CT score in the groups with and without asthma was 20.37 ± 4.34 and 17.47 ± 4.75, respectively (p < 0.01). Asthma has no influence on QoL and endoscopic findings of patients with NP, however it influences minor symptom score and CT findings.
