SOCS1 methylation level is associated with prognosis in patients with acute-on-chronic hepatitis B liver failure

BACKGROUND: Glucocorticoids could greatly improve the prognosis of patients with acute-on-chronic hepatitis B liver failure (ACHBLF). Suppressor of cytokine signaling (SOCS) 1 methylation has been shown to be associated with mortality in ACHBLF. METHODS: Eighty patients with ACHBLF were divided into group glucocorticoid (GC) and group conservative medical (CM). Sixty patients with chronic hepatitis B (CHB), and Thirty healthy controls (HCs) served as control group. SOCS1 methylation levels in peripheral mononuclear cells (PBMCs) was detected by MethyLight. RESULTS: SOCS1 methylation levels were significantly higher in patients with ACHBLF than those with CHB and HCs (P < 0.01, respectively). Nonsurvivors showed significantly higher SOCS1 methylation levels (P < 0.05) than survivors in both GC and CM groups in ACHBLF patients. Furthermore, the survival rates of the SOCS1 methylation-negative group were significantly higher than that of the methylation-positive group at 1 month (P = 0.014) and 3 months (P = 0.003) follow-up. Meanwhile, GC group and CM group had significantly lower mortality at 3 months, which may be related to application of glucocorticoid. In the SOCS1 methylation-positive group, the 1-month survival rate was significantly improved, which may be related to GC treatment (P = 0.020). However, no significant difference could be observed between the GC group and CM group in the methylation-negative group (P = 0.190). CONCLUSIONS: GC treatment could decrease the mortality of ACHBLF and SOCS1 methylation levels might serve as prognostic marker for favorable response to glucocorticoid treatment.
