s Observation on the Effect of Sequentially Combined Multi-modal Artificial Liver Treatment on HBV-related Acute-on-chronic Liver Failure

Objective: To observe the short-term effect of sequentially combined multimodal artificial liver treatment (SCMALT) on HBV-related acute-on-chronic liver failure (HBV-ACLF). Methods: HBV-ACLF patients 155 cases undergoing artificial liver treatment were analyzed, and they were sorted into the SCMALT group and the conventional-modal artificial liver treatment (CALT) group. The clinical data of all patients were recorded and the serum levels of interleukin-8 (IL-8), chemokine interferon-inducible protein-10 (IP-10), and interleukin-6 (IL-6) were detected. The changes in the 30-day survival rate, cytokine level, model for end-stage liver disease (MELD) score, and complications of artificial liver treatment were analyzed. Results: After being followed up for 30 days, 104 patients survived and 51 died. At the end of the whole-course treatment, the decreases in IL-6, IP-10, and IL-8 levels and MELD scores in the SCMALT group were greater than in the CALT group. Cox regression suggested WBC (OR=1.066, 95% CI 1.012-1.123, P=0.017), AT-III activity (OR=0.935, 95% CI 0.907-0.964, p=0.000) at baseline, artificial liver treatment mode (OR=0.362, 95% CI 0.164-0.800, p=0.012), number of artificial liver treatments (OR=0.656, 95% CI 0.436-0.986, p=0.043), spontaneous peritonitis (OR=0.337, 95% CI 0.165-0.689, p=0.003), and hepatic encephalopathy (OR=0.104, 95% CI 0.028-0.388, p=0.001) were independent influencing factors of 30-day survival rate. SCMALT can significantly prolong the survival period of the patient. No obvious difference was shown in the proportions of bleeding and circulation instability between the two groups (p>0.05). Conclusion: Compared with the CALT, SCMALT can more effectively remove inflammatory mediators and reduce the MELD score in HBV-ACLF patients, which can obviously ameliorate the prognosis, with less effect on the platelet count.
