#386 A Prospective Evaluation of the Effects of Chronic Proton Pump Inhibitor Use on Plasma Biomarker Levels in Humans
Introduction: Proton pump inhibitors (PPIs) are used primarily to treat gastroesophageal reflux disease. PPI-induced achlorhydria increases circulating gastrin and chromogranin A (CGA). CGA is a widely used biomarker for the diagnosis and follow-up for gut-based neuroendocrine tumors (NETs). PPI-induced increases in CGA or gastrin may falsely suggest the presence of a NET when none exists. Pancreastatin, a fragment of CGA, is also commonly used to diagnose and follow NETs.
