[Clinical effects assessment of nasal cellulose powder on allergic rhinitis].

Objective:To evaluate the role of nasal cellulose powder locally applied in allergic rhinitis patients.Method:Fifty patients with allergic rhinitis were divided randomly into two groups: the study group and the control group. The study group were treated with nasal cellulose powder while the control group were treated with physiological sea water.Objective and subjective examinations (nasal airway resistance, nasal syndrome score, rhinoconjunctivitis qualityof life questionnaire and olfactory function,nasal mucus cilia clearance ) were performed before and 3 months after treatment.Result:After treatment, partial parameters in nasal syndrome store ( nasal itching, nasal discharge,sneezing and total store) and rhinoconjunctivitis qualityof life questionnaire (sleep, nasal symptom, non-hay-fever symptom, emotional function and total score) in the study group were significantly improved than those in the control group (P< 0.05). However, no significant difference was found in olfactory function, Nasal airway resistance, nasal mucus cilia clearance and the eye symptom in rhinoconjunctivitis qualityof life questionnaire between the two groups after treatment (P> 0.05). No adverse reaction was found in both groups.Conclusion:Nasal cellulose powder can help alleviate clinical symptoms and improve the quality of life in allergic rhinitis patients with no significant side effect.
