Abstract

Background: Gastrointestinal bleeding (GIB) is a common complication in cirrhosis. Renal dysfunction may be crucial for the outcomes of cirrhotic patients with acute GIB. This study aimed to explore the incidence and mortality of renal dysfunction in cirrhotic patients with acute GIB. Methods: The PubMed, EMBASE, and Cochrane Library databases were searched. We pooled the incidence and mortality of renal dysfunction in cirrhotic patients using a random-effect model. Odds ratio (OR) with 95% confidence interval (CI) were calculated. Results: Seventeen studies were included. The pooled incidence of renal dysfunction was 21% (95%CI = 16%-25%) in cirrhosis with acute GIB. In subgroup analyses, the pooled incidence of renal failure, acute kidney injury (AKI), and renal impairment were 21%, 25%, and 15%, respectively. The pooled mortality was 46% (95%CI = 37%-55%) in cirrhosis with acute GIB and renal dysfunction. In subgroup analyses, the pooled mortality in patients with renal failure, AKI, and renal impairment were 42%, 47%, and 49%, respectively. Renal dysfunction significantly increased the mortality of cirrhosis with acute GIB (OR = 4.92; 95%CI = 3.47–6.96; P < 0.001). Conclusion: Renal dysfunction is a common indicator for poor outcome of cirrhosis with acute GIB. Prevention of renal dysfunction in such patients should be further explored.
