Objective: To explore the predictive effect of systemic immune inflammatory index (SII) combined with neutrophil-to-lymphocyte ratio (NLR) on prognosis of acute-on-chronic liver failure (ACLF) patients.
Methods: A retrospective analysis was conducted on the data of 160 patients diagnosed with hepatitis B virus (HBV)-ACLF in Hunan Provincial People's Hospital from June 2022 to June 2023. The patients were divided into a survival group and a death group based on their survival status within 90 days after admission. General data, laboratory indicators, and complications were recorded. The risk factors affecting prognosis of HBV-ACLF patients and the correlation between NLR, SII, and model for end-stage liver disease (MELD) score were analyzed, and the predictive effect of NLR and SII on prognosis was evaluated.
Results: Compared to the survival group, the age, MELD score, and incidence of infection of the death group were higher, and the expression levels of total bilirubin, aspartate aminotransferase, serum creatinine, white blood count, neutrophil, NLR, SII, and international normalized ratio were increased, while the expression levels of alanine aminotransferase, platelets and lymphocytes were decreased (all P<0.05). NLR, SII and MELD score were all risk factors affecting the prognosis of HBV-ACLF patients (all P<0.001). There was a positive correlation between NLR, SII and MELD score (P<0.001). SII combined with NLR showed good performance in predicting the prognosis within 90 days after admission in ACLF patients.
Conclusion: SII combined with NLR has a good prognostic effect on ACLF patients.
