However, studies of the IL-33/ST2 pathway in HBV-related acute-on-chronic liver failure（HBV-ACLF） are lacking. The present study aimed to determine the prognostic role of serum IL-33/soluble ST2（s ST2） in HBV-ACLF.METHODS： Serum levels of IL-33 and sS T2 in healthy controls（HC, n=18）, chronic hepatitis B（CHB, n=27） and HBV-ACLF（n=51） patients at the 1st and 4th week after enrollment were detected using ELISA, and clinical data were collected. The follow-up of HBV-ACLF patients lasted for 6 months at least.RESULTS： There was no significant difference of serum IL-33 level among HC, CHB and HBV-ACLF patients at week 1.However, serum s ST2 level differed significantly among the three groups： highest in the HBV-ACLF group, moderate in the CHB group and lowest in the HC group. There was a reverse correlation between serum s ST2 level and the survival of HBV-ACLF patients. The level of serum s ST2 in HBV-ACLF survivors was significantly declined from week 1 to week 4 following the treatment, whereas that in HBV-ACLF nonsurvivors remained at a high level during the same period. Furthermore, serum sS T2 level was significantly correlated with laboratory parameters and the most updated prognostic scores（CLIF-C OF score, CLIF-C ACLF score and ACLF grades）. Thereceiver operating characteristics curves demonstrated that serum sS T2 level was a good diagnostic marker for predicting the 6-month mortality in HBV-ACLF patients, comparable to the most updated prognostic scores. Serum sS T2 cut-off points for predicting prognosis in HBV-ACLF patients were 76 ng/mL at week 1 or 53 ng/mL at week 4, respectively. HBV-ACLF patients with serum sS T2 level above the cut-off point often had a worse prognosis than those below the cut-off point.CONCLUSION： Serum s ST2 may act as a promising biomarker to assess severity and predict prognosis of patients with HBV-ACLF and help for the early identification and optimal treatment of HBV-ACLF patients at high risk of mortality.展开更多

METHODS: Eighty-eight patients with exudative AMD and 45 sex-and age-matched healthy controls were enrolled in this study conducted in China. Serum samples was obtained from the patients with exudative AMD and from the controls. Serum sCD146 and VEGFR2 protein levels were measured using an enzyme-linked immunosorbent assay.RESULTS: We found that serum sCD146 and VEGFR2 protein levels were significantly higher in the patients with exudative AMD group than in the controls(t=3.859, P<0.001 and t=3.829, P<0.001, respectively). Serum sCD146 levels were significantly higher in patients with classic choroidal neovascularization(CNV) than in those with occult CNV(t=9.899, P<0.001). There was a significant difference in the trend for exudative AMD in the highest versus lowest quartile of circulating sCD146 levels(χ2=10.29, P=0.001). The receiver operating characteristic curve analysis showed that the area under the curve was 0.696 for s CD146(95%CI: 0.601-0.791) with an optimum diagnostic cut-off value of 157.16 ng/mL, a sensitivity of 55.7%, and a specificity of 82.2%.CONCLUSION: The serum sCD146 level increases and may be a biomarker for exudative AMD.展开更多
