Abstract:

Objective

To investigate the characteristics of gastroesophageal reflux associated chronic cough (GERC) with laryngopharyngeal reflux (LPR).

Methods

According to the criteria of inclusion, exclusion and diagnosis, a total of 60 patients with chronic cough who were hospitalized in the people's Hospital from January 2019 to June 2019 were selected as the study group, and the refluxsymptom index (RSI) questionnaire survey, cough symptom score, high-resolution esophageal manometry and 24-hour pH monitoring were conducted to analyze reflux characteristics.

Results

After analysis of 24 h pH monitoring, the number of reflux, the percentage of acid exposure time and DeMeester score the patients were further divided into two groups: non acid GERC group (n=32) and acidic GERC group (n=28). In non acid GERC group, the RSI score was significantly higher than that of acid GERCgroup [25.00 (8.00) vs 16.00 (6.50); Z=-3.105, P=0.001]. In addition, the scores of "continuous voice clearing" and "dyspnea or asphyxia attack" in non acid GERC patients were more significant than those in acidicGERC patients.

Conclusion

The patients with LPR and GERC was partially overlapped, and the patients with higher RSI may show more non acid reflux and dyspnea.
