Article Abstract

The relationship between chronic obstructive pulmonary disease (COPD) and reflux esophagitis (RE) was controversial. We investigated the factors influencing RE development in patients with COPD and evaluated the association between RE and AECOPD.Patients with COPD who underwent esophagogastroduodenoscopy from January 2003 to December 2013 in St. Paul's Hospital, the Catholic University of Korea (Seoul, Korea) were enrolled retrospectively. The grade of RE was based on the Los Angeles classification and minimal change esophagitis. Body mass index, smoking history, medical history, AECOPD, pulmonary function test data, endoscopic findings, and comorbidities were reviewed.Of a total of 218 patients with COPD, 111 (50.9%) were diagnosed with RE. None of age, sex, smoking history, or the severity of airflow limitation was associated with RE. AECOPD was not related to either the presence or severity of RE. There was no significant correlation between RE grade by Los Angeles classification and severity of airflow limitation (P = .625). Those who had RE used theophylline (P = .003) and long-acting muscarinic antagonists (P = .026) significantly more often than did controls. The use of theophylline (OR 2.05; 95% CI, 1.16-3.65, P = .014) was associated with an increased incidence of RE.The use of theophylline might increase the risk of RE in COPD patients. RE may not be associated with airflow limitation or AECOPD.
