Erosive Esophagitis Worsens Reflux Signs and Symptoms in Asthma Patients Without Affecting Pulmonary Function Tests

Abstract

Objectives. To determine whether erosive esophagitis (EO) worsens reflux signs and symptoms and affects pulmonary function test in asthma patients. Methods. Sixty asthma patients with gastroesophageal and laryngopharyngeal reflux symptoms were included. Spirometry, reversibility test, esophagogastroscopy, laryngoscopy, and esophagogastroscopic biopsies were conducted. Results. EO was diagnosed in 25% (n = 15) of the patients. The remaining 45 patients were placed into the non-erosive esophagitis (NEO) group. Of the 15 EO patients, grade 1 esophagitis was identified in 75% (n = 9), grade 2 in 12.5% (n = 3), and grade 3 in 12.5% (n = 3). Pulmonary function test results were not significantly different between the EO and NEO groups. Gastroesophageal and laryngopharyngeal reflux symptoms such as regurgitation, dysphagia, dyspnea, globus sensation, dysphonia, and sore throat were more frequent in EO patients than in the NEO group. The reflux finding score (RFS) was 7.33 and 4.55 in EO and NEO patients, respectively (p □ .001). Posterior commissure hypertrophy was the most common laryngoscopic finding in both of the groups followed by diffuse laryngeal edema, erythema, and pseudosulcus. Conclusions. Gastroesophageal and laryngopharyngeal reflux symptoms were more frequent in EO patients than in the NEO group. The laryngoscopic findings of laryngopharyngeal reflux were more severe and the RFS was significantly higher in EO patients than in NEO patients. The presence of EO seems to be associated with an increase in reflux without affecting pulmonary function as EO did not cause a significant decrease in pulmonary function tests.
