Background: Rhinosinusitis is a nasal and paranasal sinus infection. Chronic infection and allergies are two major causes of nasal polyp formation. Objectives: In this study, we examined the relationship between NO and aeroallergens to determine the relationship between exhaled nitric oxide level and sensitivity to aeroallergens in chronic rhinosinusitis with nasal polyps (CRSwNP) patients referring to Hazrat Rasool Hospital in Tehran from December 2016 to May 2017. Methods: A cross-sectional study was conducted on 72 patients. The prick test and exhaled NO measurements were done to determine allergens in CRSwNP patients. Statistical analysis was done to determine the relationship between the allergy and sensitivity to indoor aeroallergens in patients with CRSwNP. Results: The correlation coefficient of. 0.014 and 0.001 were evaluated for Mosquito and Cockroach respectfully, which were significantly correlated with nitric oxide. The less correlation with nitric oxide was 0.003, which was evaluated for MUCOR. Conclusions: This study showed that most people with CRSwNP had a sensitivity to at least one indoor aeroallergen, and cockroaches were the most common allergen in patients with CRSwNP with a 17.9% prevalence. This study showed that the correlation of FeNO with the sensitivity of these patients to home aeroallergens can be used, and this correlation for mosquito and cockroach aeroallergens is very valuable. The NO level and prick testing of aeroallergens can be used to estimate the relapse or lack of appropriate response to medical treatment in patients with CRSwNP.
