Purpose
The overall purpose of this project is to develop and validate a simple, non-invasive method to detect aspiration of gastro-intestinal fluid into the respiratory tract. In the inpatient setting, the investigators will compare the quantity of cromolyn detected in urine collected overnight after 4 ingestions (at 2h intervals) of a 200 mL of a 1mg/mL solution of cromolyn sodium, by 5 healthy control subjects and 5 patients (3-6 with pulmonary fibrosis; and 3-6 either awaiting or recently undergone lung transplantation) with clinical and laboratory evidence of GER (gastroesophageal reflux) with microaspiration. In the outpatient setting, the investigators will compare the quantity of cromolyn detected in urine collected overnight after 1 ingestions (at 4h intervals) of a 200 mL of a 1mg/mL solution of cromolyn sodium, by 10 patients (3-6 with pulmonary fibrosis; and 3-6 either awaiting or recently undergone lung transplantation) with clinical and laboratory evidence of GER (gastroesophageal reflux) with microaspiration.
