ABSTRACT

Acute-on-chronic liver failure (Acute-on-chronic liver failure, ACLF) is acute liver function decompensation on the basis of chronic liver disease. The progression of ACLF develops from advanced phase, plateau phase to remission phase. The pathophysiological basis of ACLF in different phases is various. In advanced phase, immune imbalance and systemic inflammatory reaction plays key roles. In this study, we try to assess the association between expression of NK cells and its receptors and prognosis of patients with ACLF in advanced phase. A total of 35 inpatients with HBV acute-on-chronic liver failure in advanced phase were recruited. They were divided into case group (n = 18) and control group (n = 17) according to whether the patients was dead in the 12 weeks. PBMC were detected for the frequency and expression of NK cell receptors by flow cytometric analysis. Our results demonstrated that patients who died had lower expression of NK cells and inhibitory receptor KIR3DL1, higher levels of FASL. During 12-week follow-up in those case alive, we found that NK cells increased, while expression of FASL decreased. High short-term mortality of ALCF was associated with NK cell, especially related to KIR3DL1 and FASL (PNK = 0.036, PKIR3DL1 = 0.0265, PFasL = 0.0008).
