BACKGROUND/AIMS: Bronchiectasis is aggravated by gastroesophageal reflux disease (GERD) owing to micro aspiration. Some researchers note the effect of antireflux surgery in bronchiectasis with GERD. However, few have investigated the effects of medical antireflux therapy. We investigated the effect of proton pump inhibitors (PPIs) in bronchiectasis with GERD.

METHODS: From March 2003 to May 2015, the clinical records of patients who had bronchiectasis with GERD were reviewed. Patients underwent an initial pulmonary function test (PFT) and chest computed tomography when diagnosed with bronchiectasis. One group with typical GERD symptoms was treated with PPIs, while the other group was not. Both groups underwent PFTs within six months after completing PPI therapy. Population characteristics and associations were compared between the groups.

RESULTS: Two hundred and fifty-seven patients (124 male, 133 female; mean age 67.6±10.0 years) were included. There were no significant differences between the groups in terms of forced vital capacity (FVC; p=0.239), forced expiratory volume in one second (FEV1; p=0.555), or FEV1/FVC (p=0.374) after PPI therapy. However, there were significant improvements in FVC (p=0.002) and FEV1 (p=0.006) in patients with high BMI in the PPI treatment group.

CONCLUSIONS: PPIs have no effect on the pulmonary function in patients with bronchiectasis and GERD. However, PPIs were noted to produce improvements in lung function in patients with bronchiectasis and high BMI.
