摘要

Background

Sarcopenia is prevalent in patients with chronic liver diseases, especially in cirrhosis patients. While sarcopenia is identified as a predictor of mortality in cirrhosis, its influence on acute-on-chronic liver failure (ACLF) remains unclear. This systematic review with meta-analysis aimed to explore the prognostic value of sarcopenia in ACLF patients.

Methods

A comprehensive online literature search was performed in Medline (via PubMed), Web of Science, Embase, and Cochrane Library, and eligible studies were screened according to the predetermined criteria. The quality of the included studies was assessed by using the revised Cochrane Collaboration Risk of Bias Tool for randomized-control studies and the Newcastle-Ottawa Quality Assessment Scale for observational studies. Available outcomes measured by odds ratio (OR), hazard ratio (HR), and risk ratio (RR) with a 95% confidence interval (CI) were extracted and further included in the meta-analysis. Stata (version 18.0) was used for all statistical analyses.

Results

Nine studies were included in further analysis. The pooled prevalence of sarcopenia was 53.3% (95% CI: 53.26 − 71.23%). The presence of sarcopenia was positively associated with 28-day mortality (HR = 2.11, 95% CI: 1.50–2.95, p < 0.001, I2 = 0.0%; OR = 2.73, 95% CI: 1.37–5.42, p = 0.004, I2 = 0.0%), 90-day mortality (HR = 1.66, 95% CI: 1.13–2.46, p = 0.01, I2 = 72.3%), and overall mortality (HR = 1.81, 95% CI: 1.30–2.51, p < 0.01, I2 = 0.0%). When using continuous variables to describe sarcopenia, a 1-unit increase in these indicators was almost significantly related to reduced 90-day mortality (HR = 0.98, 95% CI: 0.95-1.00, p = 0.052, I2 = 0.0%) and significantly associated with lower 1-year post-transplantation mortality (HR = 0.91, 95% CI: 0.85–0.98, p = 0.012, I2 = 32.7%).

Conclusion

Current evidence illustrates that sarcopenia is an unfavorable factor for both short- and long-term prognosis. More studies are needed to validate these findings in the future.
