Analytic Study Of The Differences Of Allergy Between Asal Polyps And Antrochoanal Polyps

Objective: To study the relation of etiology and pathogenesis between Nasal polyps(NP) and Antrochoanal polyps (ACP) by comparing the allergen test results of the patientswith two types of Nasal disease. Methods: A retrospective analysis of allergen skin pricktest (SPT) results between42cases of NP and19patients diagnosed with ACP whichfrom January2010to December2012in our patients. Results: the test results show thattested with44kinds of allergens, positive ratio (at least one allergen was positive) is47.6%(20cases in42patients) in patients with NP, and31.6%(6cases in19patients) inpatients with ACP,17kinds of allergens including candida albicans, cross-linking sporemold, pine, curry, fruit, meat, fish, pineapple, apples, bananas, strawberries, peaches,tomatoes, grapes, potatoes, spinach and milk were not appear allergic reaction (AR)through the test, and other27kinds of allergens in all61subjects appeared at least onepositive result. As a result, in the other27kinds of allergens, negative rate of SPT testresults in ACP patients is obviously higher than that of patients with NP, difference isstatistically significant (P<0.05), and the Z value is-5.0445. Conclusion: the etiology andpathogenesis of NP and ACP may be different, compared with NP, AR plays lesssignificant role in causing and the developing ACP, and AR may be one of the causes ofNP.
