Abstract

Purpose

Bloodstream infection (BSI) is an important cause of adverse outcomes for recipients with liver transplantation (LT). This meta-analysis aimed to identify risk factors associated with post-LT BSI.

Methods

Relevant studies published up to June 2017 were searched from seven electronic databases. The studies were reviewed according to the inclusion and exclusion criteria. The Z test was used to determine the pooled odds ratio (OR) or standardized mean difference (SMD) of the risk factors. ORs and their corresponding 95% confidence intervals (CIs), or SMDs and their corresponding 95% CIs were used to identify the significant difference of risk factors.

Results

Seventeen studies enrolling 4410 recipients were included. Eleven risk factors were identified to be associated with BSI after LT: male recipient (OR = 1.28), ascites (OR = 1.68), model for end-stage liver disease (MELD) score (SMD = 0.20), Child–Pugh class C (OR = 1.69), operation time (SMD = 0.18), incompatible blood type (OR = 2.87), operative blood loss (SMD = 0.33), rejection (OR = 1.72), biliary complications (OR = 1.91), hemodialysis (OR = 3.37), and retransplantation (OR = 2.86).

Conclusions

Although some risk factors were identified as significant factors for BSI after LT, which may provide a basis for clinical prevention, well-designed prospective studies should be done to overcome the limitations of this study.
