ABSTRACT
Background: T helper (Th) 17 cells participate in the pathogenesis of liver diseases but their exact role in acute-on-chronic hepatitis B liver failure (ACHBLF) still remains obscure. Aims: This present study was aimed to characterize the circulating Th17 cells and to analyze their association with disease progression in ACHBLF. Methods: This retrospective study consisted of 40 ACHBLF patients, 40 chronic hepatitis B (CHB) patients and 20 healthy controls. The frequency of peripheral Th17 cells and IL-17 mRNA level in peripheral blood mononuclear cells (PBMCs) were estimated by flow cytometry and relative quantitative real-time polymerase chain reaction. Results: We found that the frequency of peripheral Th17 cells, as well as the level of IL-17 mRNA in PBMCs, was significantly increased in ACHBLF patients compared with CHB patients and healthy controls. In ACHBLF patients, the frequency of Th17 cells was positively correlated with serum total bilirubin ( r = 0.392, P = 0.012) and model for end-stage liver disease scores ( r = 0.383, P = 0.015), but negatively correlated with prothrombin activity ( r = −0.317, P = 0.046). The same trend was observed as for relative expression of IL-17. Furthermore, the frequency of Th17 cells and IL-17 mRNA level were significantly elevated in non-survivors compared with survivors in ACHBLF patients. Conclusions: These results suggested that Th17 cells as well as IL-17 might be related with disease severity and prognosis in ACHBLF patients.
