INTRODUCTION: Gastroesophageal reflux disease (GERD) plays an important role in lung transplant (LT) outcomes. This study aims to evaluate the impact of a novel sleep positioning device (SPD) on lung function in LT recipients with GERD.
METHODS: In this single-center cohort study, LT recipients (2014 to 2019) with GERD who were prescribed an SPD within 2 years of LT were included. A historical control group of LT recipients with GERD on PPI only (2011 to 2013) was selected to compare forced expiratory volume in 1 second (FEV1) as a marker of lung function.
RESULTS: Twenty LT recipients using SPD (cases) and 54 patients in the historical control group with proven GERD were included. Mean (SD) interval between LT and SPD prescription was 8.6 (5.7) months. Mean % predicted FEV1 was higher in SPD users than controls post-LT at 6 months (80% vs. 69%) and 1 year (80% vs. 71%), respectively. Among SPD users, post-SPD FEV1 was higher than pre-SPD FEV1 (82% vs. 70%).
CONCLUSION: Use of a novel SPD can stabilize or improve pulmonary function in patients with GERD after LT. SPD may be a safe and cost-effective adjunctive therapy for the management of GERD after LT.
