Fat malabsorption contributes to poor nutritional status in people with cystic fibrosis (CF) and exocrine pancreatic insufficiency (EPI). Prescribing gastric acid-reducing agents such as proton pump inhibitors (PPIs) and histamine receptor antagonists (H2RAs) as an adjunct to pancreatic enzyme replacement therapy (PERT) to improve PERT efficacy and dietary fat absorption has become accepted clinical practice in CF, despite limited evidence to support the practice. Establishing the efficacy and true health benefit of acid suppression for nutritional status and outcomes in CF is particularly important in light of potential health risks and cost associated with long-term or even lifetime use of these medications.
This study aims to characterize changes in fat malabsorption using the coefficient of fat absorption (CFA) as the primary endpoint in subjects who are on and off acid suppression with a PPI in addition to PERT. Additionally, the SmartPill® will be used to evaluate duodenal power of hydrogen (pH) while on and off acid suppression, and the malabsorption blood test (MBT) will be used to characterize changes in fat absorption. Associations will be explored between changes in nutritional status (weight, height, BMI), clinical GI symptoms, and quality of life in subjects treated with PPI vs. placebo.
