ABSTRACT
Acute kidney injury (AKI) frequently occurs in hospitalized individuals with liver cirrhosis and represents a significant risk factor for early in-hospital mortality, holding crucial clinical and prognostic importance. The objective of this meta-analysis was to assess the risk factors associated with AKI in hospitalized individuals with cirrhosis. This systematic review and meta-analysis was conducted in concordance with guidelines provided by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement. Two independent researchers systematically searched major databases, including MEDLINE/PubMed, Web of Science, and EMBASE, from January 2015 until December 2023. A total of 14 studies were included in this meta-analysis, of which six were prospective, and the remaining were retrospective. Of the 9,659 cirrhosis patients in the 14 included studies, 3,968 had developed AKI with a pooled incidence of 41% (95% confidence interval = 34-47%). Our findings showed that a high Model for End-Stage Liver Disease (MELD) score, infection, high Child-Pugh-Turcotte stage score, high serum creatinine, high serum bilirubin, and low serum albumin were significantly associated with high incidence of AKI in liver cirrhosis patients. The results emphasize the importance of vigilant monitoring in cirrhosis patients to detect any indications of AKI, followed by meticulous and attentive management.
