Résumé
OBJECTIVE@#To investigate the effects of prophylactic drugs on allergic rhinitis.@*METHOD@#Thirty patients diagnosed as allergic rhinitis based on mugwort allergen were randomly divided into three groups: budesonide group (n = 10), saline group (n = 10) and control group (n = 10). The patients in budesonide group and saline group respectively received budesonide nasal spray (64 microg per, 256 microg once daily) and saline nasal spray twice daily starting two weeks before the date which the patient onset last year and continuing up to the end of the pollen season. The patients in control group were treated without any processing. The nasal symptom scores and attack times of the three groups was recorded.@*RESULT@#During the pollen season, 2 patients attacked in the budesonide group (20%), and all the patients attacked in saline group and control group (100%). Statistical significance was found among the three groups (P < 0.01), and between budesonide group and the other two groups (P < 0.01). The budesonide group had lower symptom score than the other two groups and a postponed attack time. All the differences had Statistical significance (Value of chi-square statistic = 21. 558, P < 0.01, Fisher exact test P < 0.01).@*CONCLUSION@#Prophylactic administration of budesonide, starting two weeks before the date which the patient onset may release symptom and even avoid the attack of the allergic rhinitis based on mugwort allergen.
