ARTICLE HIGHLIGHTS
Research background

Since hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) is a syndrome with a high short-term mortality rate, and clinically identifying those patients at a high mortality risk is of great significance.

Research motivation

The aim of this study was to investigate the clinical value of soluble mannose receptor (sMR) in patients with HBV-ACLF.

Research objectives

To investigate the clinical value of sMR for predicting 90-d mortality of patients with HBV-ACLF.

Research methods

A total of 43 patients with HBV-ACLF were enrolled in this retrospective study, and their serum sMR levels were determined using an enzyme-linked immunosorbent assay. A multivariate logistic regression analysis was used to analyze the independent risk factors for mortality.

Research results

When compared with chronic hepatitis B patients and healthy controls, serum sMR level was significantly higher in HBV-ACLF patients. Serum sMR helped to distinguish the survivors from non-survivors, and it was positively correlated with model for end-stage liver disease (MELD) score, HBV-DNA level, and total bilirubin level. In addition, serum sMR level was an independent risk factor and significantly improved the performance of MELD score in predicting the prognosis of HBV-ACLF patients.

Research conclusions

Serum sMR level is significantly elevated in patients with HBV-ACLF, and it is significantly associated with indicators of liver injury and disease severity. Additionally, sMR level is negatively correlated with patients outcome. Finally, sMR level may be a predictor of the prognosis of patients with HBV-ACLF.

Research perspectives

Future studies are needed to investigate the mechanisms underlying the role of sMR. And it is necessary to determine the dynamic changes in serum sMR during the progression of HBV-ACLF. Multicenter trials with large sample sizes are also required to confirm the current findings.
