Abstract

<abstract> <title> <x xml:space="preserve">Abstract</x> </title> <p> <italic>Background</italic>: Upper gastrointestinal bleeding (UGIB) is a major cause of clinical bleeding among patients with end-stage renal disease (ESRD). This study aimed to investigate the association between mortality and UGIB in patients with uremia. <italic>Methods</italic>: From 2004 to 2010, a tertiary hospital-based retrospective cohort comprising 322 patients undergoing hemodialysis was investigated. All the patients were diagnosed with UGIB according to the International Classification of Diseases, 9th Revision (ICD-9) that included peptic ulcer bleeding, duodenal ulcer bleeding, and other symptoms. UGIB was required to be one of the first three discharge diagnoses. Rehospitalization within 3 days after discharge was regarded as the same course. Exclusion criteria were age <20 years, previous gastric resection or vagotomy, esophageal and gastric variceal bleeding, or gastric cancer within the first 2 years of the index hospitalization. <italic>Results</italic>: The all-cause in-hospital mortality rate of patients with UGIB undergoing hemodialysis was high, with the first-month mortality rate of 13.7%, sixth-month mortality rate of 26.7%, and first-year mortality rate of 27.0%. Using Cox regression models, we found that the high mortality rate of the UGIB group was significantly correlated with older age [adjusted hazard ratio (HR) = 1.02, 95% confidence interval (CI) = 1.01–1.04], female sex (adjusted HR = 1.62, 95% CI = 1.05–2.51), infection during hospitalization (adjusted HR = 1.85, 95% CI = 1.13–3.03), single episodic UGIB (adjusted HR = 2.00, 95% CI = 1.08–3.70), abnormal white blood cell (WBC) count (adjusted HR = 1.59, 95% CI = 1.03–2.45), and albumin level ≤3 g/dL (adjusted HR = 2.67, 95% CI = 1.51–4.72). <italic>Conclusion</italic>: In conclusion, patients with ESRD who are admitted with primary UGIB have a profoundly increased risk of all-cause in-hospital mortality during the follow-up period.</p> </abstract>
