Leukotriene D4 Nasal Provocation Test in Allergic Rhinitis

NCT01963741

RandomizedCrossoverSingle-blindDiagnostic

Summary

Leukotrienes play critical roles in the inflammatory process in allergic rhinitis and bronchial asthma, therefore, anti-leukotriene therapy is part of treatment for asthma. However, not all allergic rhinitis accompanied with or without asthma treated with anti-leukotriene were effective. So it is critical to develop a method to identify the response subgroup. In this study, it is assumed that nasal physiological responsiveness to leukotriene nasal provocation test (NPT) is able to gain evidence on the effect of leukotriene on the development of allergic rhinitis and asthma, and is helpful to the use of anti-leukotriene agent. The purpose of the study is to establish the methodology and diagnostic value of leukotriene D4 (LTD4) nasal provocation.
