It is well established that continuous proton-pump inhibitor (PPI) therapy could significantly increase serum CgA level via hypergastrinemia, but the effect of a single dose of PPI on serum CgA level has not yet been evaluated. Aim: To analyze the acute effect of a single dose of PPI on serum CgA levels during fasting and postprandial, over a period of four hours. Patients and methods:…
