  •   Objective  To investigate the expression of myeloid-derived suppressor cells (MDSC), regulatory T cells (Treg), IL-17-producing CD4+ T cells (Th17), and CD8+ T cells (Tc17) in hepatitis B virus-related acute-on-chronic pre-liver failure (pre-ACHBLF), and to provide ideas for the early treatment of acute-on-chronic hepatitis B liver failure (ACHBLF).  Methods  A total of patients with pre-ACHBLF and 15 patients with ACHBLF who were hospitalized in Shijiazhuang Fifth Hospital, from August 2018 to May 2019 were enrolled as subjects, and 15 patients with chronic hepatitis B (CHB) and 15 healthy controls (HC) who underwent physical examination were enrolled as controls. Flow cytometry was used to measure the expression levels of MDSC and Th17, Treg, and Tc17 cells in peripheral blood; a blood analyzer was used to measure routine blood parameters and calculate neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), and systemic immune-inflammation index(SIRS) to evaluate the degree of inflammation, and the correlation between the expression of immune cells and the degree of inflammation was analyzed. An analysis of variance for independent samples was used for comparison of normally distributed continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups; the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups, and the Nemenyi test was used for further comparison between two groups. A Pearson linear correlation analysis or Spearman's rank correlation analysis was used to investigate the correlation between variables.  Results  Compared with the CHB group, the ACHBLF and pre-ACHBLF groups had significant increases in the expression levels of Th17, Treg, and Tc17 cells, and the pre-ACHBLF group also had a significant increase in the expression level of MDSC (all P < 0.05). The correlation analysis showed that in pre-ACHBLF patients, MDSC were positively correlated with leukocyte count, neutrophil count, NLR, MLR, and SII (r=0.775, 0.727, 0.571, 0.786, and 0.846, all P < 0.05), and Treg cells were only positively correlated with leukocyte count (r=0.618, P=0.043); Th17/Treg ratio and Tc17 cells were negatively correlated with the number of lymphocytes (r=-0.790 and -0.795, both P < 0.05).  Conclusion  Cellular immune dysfunction is observed in patients with pre-ACHBLF, and the expression of MDSC is closely associated with the degree of inflammation and should be taken seriously in the early stage.
