INTRODUCTION: There are conflicting data regarding the association between allergy and chronic rhinosinusitis with nasal polyps (CRSwNP). The objective of this study was to determine whether an allergy is a contributing factor to CRSwNP.
METHODS: We conducted a prospective non-randomized controlled study comparing patients suffering from CRSwNP with participants who had no nasal symptoms. Both CRSwNP and non-CRSwNP participants underwent a skin prick test, and the odds ratio was calculated to determine the risk of having CRSwNP between those with positive and those with negative results.
RESULTS: There were 48 participants in this study with a mean age of 33.33 years. The skin prick test was positive in 15 CRSwNP patients (62.5%) and 8 participants in the control group (33.33%). The odds of having CRSwNP were 3.3 times higher in the positive skin test group than in the negative group (p = 0.046, 95% CI 1.02 to 10.90).
CONCLUSIONS: This study found a strong relationship between allergy and CRSwNP and that allergy patients have a high risk of having CRSwNP.
