ABSTRACT
Objective To explore the diagnostic significance of differential cell count in induced sputum to chronic cough and assessment of airway inflammation.Methods The sputum of 335 chronic cough patients were induced.Differential cell counts were measured in these samples.The side effects were observed during the induced procedure.The final diagnosis was made based on clinical manifestation and examination findings including pulmonary function tests,provocation test,induced sputum cell differentials, etc.Results The cause of chronic cough was defined in 322 patients.The six most important causes of cough were typical asthma(TA,n=84),eosinophilic bronchitis (EB,n=62),atopic cough (AC,n= 42),cough variant asthma (CVA,n=40),gastroesophageal reflux cough(GERC,n=37),rhinitis and/ or paranasal sinusitis (PNDs,n=32),and others and indefinite cause (n=25,13).Percentage of eosinophils were significantly increased in the induced sputum of AC,EB,CVA,and GERC patients (0.005,0.052,0.059,0.234) compared with those in other causes and the healthy controls (0) (P
