SESSION TITLE: Asthma II
SESSION TYPE: Original Investigation Poster
PRESENTED ON: Saturday, April 16, 2016 at 11:45 AM - 12:45 PM
PURPOSE: To investigate the predictive value of fractional exhaled nitric oxide (FeNO) of sputum eosinophilia in chronic cough (CC) and classic asthma (CA).
METHODS: Patients with CC and CA who referred to the Guangzhou Institute of Respiratory Disease were enrolled from 2010 to 2015. The causes of CC was confirmed according to the results of relevant tests and a successful response to the therapy for the initial diagnosis. Sputum induction and FeNO measurement were performed in all patients. Correlations between FeNO and sputum eosinophils in CC and CA were determined by Spearman rank correlation. Receiver operating characteristics (ROC) curve was constructed by using the values of FeNO.
