The Correlation About Exhaled Nitric Oxide With Allergic Rhinitis And Asthma

Objective: To study the correlation about exhaled nitric oxide withallergic rhinitis and asthma. Methods:28patients with asthma (group A),20patients with allergic rhinitis as group B, where patients with allergicrhinitis and asthma combined seven cases of group C, and then select20healthy people group D were measured in each group NO. The results: A, B,C group exhaled NO concentrations were significantly higher than those ingroup D (P <0.05); FEV1%values of A, B, C group were lower than the Dgroup, the difference was significant compared (P <0.05). Asthma andallergic rhinitis patients exhaled NO levels and FEV1%values werenegatively correlated (r=-0.348, P <0.05). CONCLUSION: exhaled NOlevels with allergic rhinitis and asthma incidence has some relevance, asnoninvasive monitoring of disease progression and a reliable indicator ofprognosis.
