RESULT (REflux Surgery in Lung Transplantation) Preliminary Study Protocol (RESULT)
10 septembre 2014 mis à jour par: Duke University
Prospective and Retrospective Study to Develop a Multi-center Randomized Study, to Determine if Prevention of GERD Related Aspiration by Surgical Fundoplication Improves Lung Allograft Function
The purpose of the prospective study is to collect information surrounding lung transplant in order to develop a randomized study to determine if prevention of gastroesophageal reflux disease (GERD) related aspiration (stomach acid coming up from the stomach into the esophagus) by surgical fundoplication improves lung rejection. Lung transplantation has evolved into an effective treatment for patients with end-stage lung disease; however, a significant limitation to long-term survival is patients develop a condition of scarring known as chronic lung rejection, which can cause lung function to deteriorate, thereby reducing a patient's chances for survival. Preliminary research has shown a correlation between the presence of gastroesophageal reflux disease (GERD) and impaired early lung rejection as assessed by a breathing test, FEV1 (the amount of forced expired air volume in 1 second).
The Investigator is interested in learning more about this condition and the potential for aspiration (inhaling fluid) injury. The primary goal of this preliminary study will be to identify aspiration markers that are correlated with adverse clinical outcomes (increased early rejection, decreased FEV1) that may be used as inclusion criteria for the future randomized trial.
The purpose of the retrospective study is to collect information surrounding lung transplant in order to develop a randomized study to determine if prevention of gastroesophageal reflux disease (GERD) related aspiration (stomach acid coming up from the stomach into the esophagus) by surgical fundoplication improves lung rejection.
The goal of this retrospective data collection is to review the following:
- subject outcome event rates for subjects with and without gastroesophageal reflux disease (GERD) for survival, Bronchiolitis Obliterans Syndrome (BOS), acute rejection and Forced Expiratory Volume in the first second (FEV-1),
- the estimated treatment effect of fundoplication on the above event rates,
- a threshold effect for Bronchiolitis Obliterans Syndrome (BOS) and/or death are more likely to occur at higher or more proximal acid or non-acid contact times.
This data will be collected in order to better design and coordinate a multicenter prospective study.

Description détaillée
Prospective Group: Approximately 125 Bronchoalveolar Lavage (BAL) samples will be collected from eligible subjects at the time of clinical bronchoscopies and will be within 2 weeks of their esophageal study. The Bronchoalveolar Lavage (BAL) samples will be assayed for bile acids; pepsin, pepsinogen I and II; trypsin; gastrin, and Lipopolysaccharide (LPS) content. Short-term clinical outcome measures including acute rejection episodes, and Forced Expiratory Volume in the first second (FEV-1) at one year will be collected. Correlation between markers of reflux and aspiration will be analyzed.
Retrospective Group: Up to 800 charts within the past 5 years will be reviewed for 1) subject outcome event rates for subjects with and without Gastroesophageal Reflux Disease (GERD) for survival, Bronchiolitis Obliterans Syndrome (BOS), acute rejection and Forced Expiratory Volume in the first second (FEV-1), 2) what is the estimated treatment effect of fundoplication on the above event rates, 3) is there a threshold effect such that events such as BOS and death are more likely to occur only at higher or more proximal acid or non-acid contact times. This review will better address the role of Gastroesophageal Reflux Disease (GERD) in lung allograft failure, the clinical utility of surgical fundoplication in preventing lung allograft injury, and the role that acid and non-acid reflux as related to aspiration causes lung allograft injury as it relates to a wider population.

BAL aspiration markers
Délai: 1 year
|
For the prospective study analysis, we will be assessing the relationship of gastroesophageal reflux and aspiration post lung transplantation with the occurrence of lung allograft dysfunction by reviewing BAL samples prospectively collected in approximately 125 subjects.
These BAL samples will be assayed for bile acids; pepsin, pepsinogen I and II; trypsin; gastrin, and LPS content.
The correlation of the aspiration biomarkers to acute rejection, BOS, death and FEV-1 at one year will be assessed.

Death
Délai: 1 year
|
For the retrospective study, the first specific goal of data collection is outcome event rates for subjects with and without GERD for survival and the estimated treatment effect of fundoplication on the above event rates.
A threshold effect for death is more likely to occur at higher or more proximal acid or non-acid contact times.
Up to 5 years of follow-up data will be available for analysis with the primary comparison at one year.
These data will be used to better design and coordinate a multicenter prospective study.
