Comparison of peptic ulcer disease risk between peritoneal and hemodialysis patients.

Background: Compared to the general population, patients with end-stage renal disease (ESRD) have increased peptic ulcer and upper GI bleeding complication rates. However, the risk factors for peptic ulcer among ESRD patients are unknown.

Methods: In this retrospective study, we enrolled 827 incident dialysis patients and diagnosed peptic ulcer on the basis of endoscopic findings; information on the morbidities and medical prescription were obtained directly from medical records.
