Abstract:

Objective

To investigate the prevalence and characteristics of swallowing related cough (SRC) in asthma patients.

Methods

A total of 94 asthmatic patients from August 2017 to November 2019 whom diagnosed with asthma in our hospital were selected as the study group, and asthma questionnaire survey was conducted to analyze whether they had SRC, as well as the related postnasal drip, heartburn, cough and acid reflux.

Results

The patients were divided two groups, 48 patients with SRC positive (51.1%) and 46 patients with SRC negative (48.9%); the main foods that causing cough in patients with SRC positive was spicy (33.3%) and sour (43.8%); the 24 hour pH monitoring showed that the weak acid reflux (%) in the proximal part of esophagus in patients with SRC positive was significantly higher than SRC negative group (P<0.05); the frequency of cough caused by postnasal drip and heartburn was significantly higher than SRC negative group (P<0.05).

Conclusion

SRC is common in asthmatic patients, which is closely related to postnasal drip, heartburn and acid reflux.

Key words: Asthma, Swallowing related cough, Acid reflux, Postnasal drip
