Asthma in Rhinosinusitis: A Survey from Iran.
BACKGROUND
The coexistence of asthma and chronic rhinosinusitis (CRS) is more common than expected given their individual prevalence in the general population and may affect patient's quality of life. The aim of this study was to evaluate the prevalence of asthma in chronic rhinosinusitis in Mashhad, Northeast Iran.


METHODS
This study was performed in two university hospital from November 2012 for 12 months. In total, 153 patients with chronic rhinosinusitis were enrolled and referred to a particular pulmonologist for asthma evaluation.


RESULTS
The mean age of participants was 40.54±13.11 years, and 41.8% were male. In total, 63.4% of patients had the polypoid form of CRS. The proportion of patients in this study with asthma was 41.8%, compared with a general asthma prevalence in this region of 13.5%.


CONCLUSIONS
There is a high prevalence of asthma among patients with CRS, but it often remains undiagnosed. Asthma in CRS patients should be diagnosed and treated in order to improve patient's quality of life. We recommend an evaluation of the lower airways in all of these patients as well as further studies in this field.
