ATP Level in Induced Sputum and Cough Sensitivity to ATP in Subjects With Refractory/Unexplained Chronic Cough
In Brief
An observational study for Refractory/Unexplained Chronic Cough. Completed, enrolled 131 participants across 1 site.
Detailed Summary
This is a cross-sectional study to investigate ATP level in induced sputum and cough sensitivity to ATP in subjects with refractory/unexplained chronic cough. 60 patients with refractory/unexplained chronic cough and 30 matched healthy controls were recruited. Demographic data, clinical characteristic, cough sacles and medical history records were collected. Cough chanllage(ATP and capsaicin) and ATP measurement in sputum were conducted.The difference of sputum ATP level between patients and control and the correlation between sputum ATP level and cough sensitivity to ATP were analyzed.
