Abstract

Background: Few large population-based studies have compared the occurrence of peptic ulcer bleeding (PUB) in cirrhotic and noncirrhotic patients. Aims: To investigate if cirrhotic patients have higher risk of PUB than the general population and to identify possible risk factors of PUB in cirrhotic patients. Methods: Using the National Health Insurance Research Database, a nationwide population-based dataset in Taiwan and matching age, gender, comorbidities and ulcerogenic medication by propensity score, 4013 cirrhotic patients, 8013 chronic hepatitis patients and 7793 normal controls were compared. The log-rank test was used to analyse differences in accumulated PUB-free survival rates between the groups. Cox proportional hazard regressions were performed to evaluate independent risk factors for PUB in all patients and identified risk factors of PUB in cirrhotic patients. Results: During the 7-year follow-up, cirrhotic patients had significantly higher incidences of PUB than chronic hepatitis patients and controls, respectively (P <0.001 by log-rank test). By Cox proportional hazard regression analysis, cirrhosis was independently associated with increased risk of PUB (hazard ratio: 4.22; 95% CI 3.37-5.29, P <0.001) after adjusting for age, gender, economic status, underlying comorbidities and ulcerogenic medication. Age, male, diabetes, chronic renal disease, history of gastro-oesophageal variceal bleeding and use of nonsteroidal anti-inflammatory drugs were risk factors for PUB in cirrhotic patients. Conclusion: Cirrhotic patients have a significantly higher risk of peptic ulcer bleeding after adjustments for possible confounding factors like age, gender, economic status, underlying comorbidities and ulcerogenic medication.
