Abstract

Background: The association of gastro-esophageal reflux (GER) with a wide variety of pulmonary disorders was recognized. We aimed to evaluate the effect of GER-induced esophagitis on airway hyper-reactivity (AHR) in patients and the response to treatment.

Materials and methods: In this cohort study, 30 patients attending the gastrointestinal clinic of a university hospital with acid reflux symptoms were included. All patients were evaluated endoscopically and divided into case group with esophagitis and control group without any evidence of esophagitis. Spirometry and methacholine test were done in all patients before and after treatment of GER with pantoprazole 40 mg daily for six months.

Results: There was a significant difference in the rate of positive methacholine test between the cases (40%) and the controls (6.7%) prior to anti-acid therapy (P < 0.0001). After six months of treatment, the frequency of positive methacholine test diminished from 40 to 13.3% in the case group (P < 0.05) but did not change in the controls (P = 0.15).

Conclusion: The presence of esophagitis due to GER would increase the AHR and treatment with pantoperazole would decrease AHR in patients with proved esophagitis and no previous history of asthma after six months.

Keywords: Airway hyper-reactivity; gastroesophageal reflux; methacholine test; spirometry.
