The Prevalence of Allergic Rhinitis in Patients with Chronic Rhinosinusitis

Introduction: Chronic rhinosinusitis (CRS) is a multifactorial disease. Allergies are considered a predisposing factor to CRS; however, this remains controversial. The objective of this research was to investigate the prevalence of co-morbidities and allergic reaction, and to specify the most common allergens in patients with confirmed CRS.   Materials and Methods: One hundred patients with signs and symptoms of CRS who met the diagnostic endoscopic and radiologic criteria of chronic rhinosinusitis were selected. They filled out a questionnaire and underwent a skin prick test for the common inhalant allergens. Allergic rhinitis was diagnosed according to the history and positive skin prick tests.   Results: The mean age of patients was ۳۴. Males were slightly more involved (۵۴%). The prevalence of polypoid and none-polypoid rhinosinusitis was ۵۴% and ۴۶% respectively. The patients’ most common symptoms were nasal discharge (۹۵%), blockage (۹۴%), smell disorders (۶۳%), cough (۴۵%), halitosis (۴۱%), lethargy (۳۷%), and aural fullness (۳۶%). Allergy to at least one allergen was noted in ۶۴% of the CRS patients which is higher than general population in Mashhad, Iran with allergic rhinitis (۲۲.۴%). Salsola was the most common allergen. There was no significant difference in allergic reactions between polypoid and non-polypoid CRS patients.   Conclusion:  Allergic reactions was found in Iranian CRS patients with or without polyposis to be much higher than general population in Mashhad with allergic rhinitis alone.
