ORIGINAL ARTICLECombination of MicroRNAs and Cytokines: a Method for Better Evaluation of Acute-on-Chronic Liver Failure by Chunwen Pu, Chunmeng Jiang, Lang Lang, Huang Hui, Zhidong Wang, Dapeng Ma, Yong Zhang

Background: The aim was to establish expression profiles of microRNAs (miRNAs) in Peripheral Blood Mononuclear Cells (PBMC) and of plasma cytokines from the patients with hepatitis B virus related acute-on-chronic liver failure (HBV-ACLF) and high-risk of acute-on-chronic liver failure (ACLF) patients as well as healthy people and to examine the relationships between these profiles and clinical features.
Methods: Herein, we collected PBMCs and plasma from peripheral blood of HBV-ACLF and ACLF patients as well as healthy people. Microarray, real-time qPCR, and ELISA assays were used.
Results: In this study, we found 39 miRNAs including miR-146a, miR-150, and miR-29a downregulated and 5 miRNAs elevated in PBMCs from HBV-ACLF patients compared to healthy controls. However, elevated plasma levels of cytokines such as TNF-α, IFN-α, and TGF-β were found in PBMCs from HBV-ACLF patients compared with the controls, but no significant difference was found between the high-risk and control groups. MiR-146a, miR-150, miR-29a, PTA, and anti-HBc were positively correlated with the survival of ACLF patients, while TNFα, IFN-α, INR, and TBiL were negatively correlated with the survival of these patients.
Conclusions: Combined examination of miRNAs in PBMCs and cytokines in plasma together is a better method for monitoring and evaluating HBV-ACLF patients.
