    Abstract:
    OBJECTIVE: This study aimed to assess the relationship between glucocorticoid treatment and mortality among patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF). METHODS: We conducted a retrospective, hospital-based cohort study from 2019 to 2022, including 394 consecutively enrolled HBV-ACLF patients at the Third Affiliated Hospital of Chongqing Medical University. We recorded patient demographics, liver function, CD163 concentration, Model for End-Stage Liver Disease (MELD) score, and complications. The primary endpoint was 30-day mortality. RESULTS: No significant differences were observed between the glucocorticoid-treated and non-glucocorticoid groups regarding sex, age, liver function, complications, or plasma CD163 concentration. After treatment, the median levels of total bilirubin (TBil), alanine aminotransferase (ALT), aspartate aminotransferase (AST), international normalized ratio (INR), and HBV DNA were 322.9 (IQR 258.6-383.3) μmol/L, 354.4 (IQR 253.1-444.6) U/L, 258.4 (IQR 186.4-322.4) U/L, 2.3 (IQR 2.1-2.5), and 5.0 (IQR 4.0-6.0) log IU/mL, respectively. Changes in ALT, AST, sCD163, TBil, INR, and MELD score before and after treatment showed no statistical differences between the glucocorticoid and non-glucocorticoid groups (P > .05). However, the mortality rate was significantly lower in the glucocorticoid group compared to the non-glucocorticoid group (11.2% vs. 29.9%, respectively; P < .001). Multivariable analysis revealed that, after adjusting for confounders, non-glucocorticoid treatment was associated with a higher adjusted hazard ratio (HR) for mortality (HR = 3.7, 95% CI 2.2-6.2) compared to glucocorticoid treatment. Additionally, an interaction test indicated that the association between non-glucocorticoid treatment and mortality was more robust in the sCD163 ≥ 18.2 mg/L group (HR = 7.6, 95% CI 2.9-19.9) but weaker in the sCD163 < 18.2 mg/L group (HR = 2.2, 95% CI 1.2-4.3) (P for interaction < .05). CONCLUSIONS: These findings suggest that glucocorticoids are an effective treatment for reducing mortality in HBV-ACLF patients, with particular effectiveness observed in patients with high sCD163 concentrations.
