  • Gastroesophageal reflux is associated with incresead exacerbation of chronic obstructive pulmonary disease

    Objective To investigate the prevalence and predisposing factors of gastroesophageal reflux(GER)in patients with chronic obstructive pulmonary disease(COPD)and its impacts on the frequency of COPD exacerbations.Methods 50 patients with acute exacerbation of COPD were enrolled in the study.All patients filled a modified version of clinically validated standardized Mayo Clinic GER questionnaire.Pulmonary function tests(PFT),body mass index(BMI),serum albumin,and medications were recorded.The patients were divided in to GER group(13 patients with GER symptoms longer than one year and diagnosed GER by gastroscope) and non-GER group(37 patients without GER symptoms).Results There were no significant differences in the BMI,serum albumin,use of inhaled steroids and theophylline between the two groups.Forced expiratory volume in one second as a percentage of the predicted value(FEV1%pred)(37% vs 38.3%,P=0.608.),residual volume % predicted(123.4 % vs 137.8%,P=0.222),and residual volume to total lung capacity(139.4% vs 141.5%,P=0.798) were not significantly different between the two groups.The number of COPD exacerbations per year was significantly higher in patients with GER compared to patients without GER(4.5 vs 1.3,P=0.006).Conclusions The severity of airflow obstruction and the hyperinflation is unlikely to contribute to the development of GER.Patients with GER experience significantly more exacerbations per year when compared to patients without GER,suggesting more highlight warrant in treatment of GER in COPD patients.
