[Relationship between chronic obstructive pulmonary disease and gastroesophageal reflux disease defined by the Frequency Scale for the Symptoms of gastroesophageal reflux disease].
Little is known about gastroesophageal reflux disease (GERD) in chronic obstructive pulmonary disease (COPD) patients. The aim of this study was to investigate the prevalence, clinical characteristics and risk factors for GERD in COPD patients, based on the Frequency Scale for the Symptoms of GERD (FSSG). In 228 COPD patients, the prevalence of GERD was 26.7%, independent of COPD stage. Logistic regression multivariate analysis revealed significant risk factors for accompanying GERD were age (p = 0.009; odds ratio (OR), 0.933; 95% confidence interval (CI) 0.885 to 0.983) and number of COPD exacerbation within one year (p = 0.043; OR, 1.675; 95% CI, 1.075 to 2.764). The risk factors of COPD exacerbation were total FSSG score (p = 0.031; OR, 1.079; 95% CI, 1.007 to 1.156) and inhaled corticosteroid use (p = 0.003; OR, 3.238; 95% CI, 1.482 to 7.076). Moreover, the Spearman rank correlation test showed that FSSG score was weakly but significantly correlated with the number of COPD exacerbations (rs = 0.317, p < 0.001). In conclusion, the incidence of GERD in COPD patients is high, and the incidence of GERD is closely related to COPD exacerbation.
