Serum thymosin beta4 levels in patients with hepatitis B virus-related liver failure.

ABSTRACT: AIM:To investigate whether serum thymosin beta4 can provide diagnostic or prognostic information in liver failure patients caused by chronic hepatitis B virus (HBV) infection. METHODS:Serum thymosin beta4 levels were measured in 30 patients with acute-on-chronic liver failure (ACLF), 31 patients with chronic liver failure (CLF), 30 patients with compensated liver cirrhosis (CR) and 32 patients with chronic hepatitis B and 30 healthy controls. Serum thymosin beta4 levels were measured by enzyme-linked immunosorbent assay and Child-Pugh and model for end-stage liver disease (MELD) scores were calculated for each patient on admission. RESULTS:Compared with healthy controls, serum thymosin beta4 levels in ACLF, CLF, CR and chronic hepatitis B patients were significantly lower, 6.5047 (4.7879-10.5314) microg/mL vs 0.4632 (0.2759-0.8768) microg/mL, 0.6981 (0.5209-1.2008) microg/mL, 1.8053 (0.8110-2.3397) microg/mL, 3.7803 (1.8570-6.4722) microg/mL, respectively (P < 0.001). The levels of thymosin beta4 in liver failure (ACLF or CLF) patients were markedly lower than that in CR (P < 0.001), and a difference was also found between CLF and ACLF patients (P = 0.038). In patients with chronic liver disease, there was a positive relationship between thymosin beta4 levels and albumin, choline esterase, and platelet (P < 0.001), and negative relationship with alanine aminotransferase (P = 0.020), aspartate aminotransferase, total bilirubin, international normalized ratio of prothrombin time, and Child-Pugh and MELD scores (P < 0.001). Of the 61 liver failure patients, the thymosin beta4 levels of non-survivors were significantly lower than that of survivors (P = 0.007). Receiver operating characteristics analysis identified a thymosin beta4 cutoff level of 0.5708 microg/mL for predicting poor prognosis in all liver failure patients. The serial thymosin beta4 values were observed in 13 liver failure inpatients. Lower initial values were observed in the death. While greater improvement in thymosin beta4 value was found in those who recovered from the disease. CONCLUSION:Serum thymosin beta4 can be used as an important potential predictor for liver failure caused by chronic HBV infection.

Project description:Purpose: Neutrophils and cytokines play a major role in the pathogenesis of acute-on-chronic liver failure (ACLF). We aimed to determine whether chemokine (CXC) ligand 1 (CXCL1), a key marker of neutrophil recruitment and activation, could predict the severity and prognosis of hepatitis B virus-related ACLF (HBV-ACLF). Methods: Hospitalized patients with HBV-ACLF were enrolled in a prospective study and stratified as survivors (alive at 28 days) and nonsurvivors (deceased at 28 days). Serum CXCL1 levels were measured in healthy controls, patients with chronic HBV, patients with HBV-related compensated cirrhosis, and patients with HBV-ACLF. Univariate and multivariable logistic analyses, Pearson correlation analysis, area under the receiver operating characteristic curve (AUROC), and Z tests were used to evaluate the performance of CXCL1 as a marker in HBV-ACLF. Results: Patients with HBV-ACLF had significantly higher serum levels of CXCL1 and neutrophil count than healthy controls and patients with chronic HBV or HBV-related compensated cirrhosis (P < 0.01, respectively). Among patients with HBV-ACLF, survivors had lower serum CXCL1 levels and neutrophil count than those of nonsurvivors (P < 0.001, P < 0.05, respectively). Serum CXCL1 level was positively correlated with neutrophil count (r = 0.256, P = 0.001), ACLF grade (r = 0.295, P < 0.001) and organ failure, including coagulation (r = 0.21, P = 0.005) and brain failure (r = 0.198, P = 0.008). Multivariable logistic analyses showed serum CXCL1 [OR (95% CI) = 1.017 (1.009-1.025), P < 0.001] was an independent risk factor for 28-day mortality in HBV-ACLF. Meanwhile, the AUROC analysis demonstrated that serum CXCL1 [0.741 (0.669-0.804)] might be a reliable prognostic biomarker for patients with HBV-ACLF. Conclusions: Overall, serum CXCL1 can serve as a biomarker indicating the severity of disease and prognosis for patients with HBV-ACLF. CXCL1 might also be a therapeutic target in this disease.

Project description:BackgroundThyroid dysfunction has been reported in severe liver diseases. The aim of this study was to analyze the impact of serum thyroid-stimulation hormone (TSH) levels on the prognosis of patients with hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF).MethodsThis retrospective cohort study included 1,862 patients with HBV-related ACLF. Risk factors associated with 30-day and 90-day survival, hazard ratios (HRs), and 95% confidence intervals (CIs) for TSH were estimated using Cox proportional hazards regression. The Area Under the ROC curve (AUROC) analysis was carried out, and the cut-off values were calculated. After grouping by the cut-off value, survival was compared between the groups using the log-rank test. This study data is from the "Survival Cohort Study (SCS)", which has been registered at ClinicalTrials.gov (NCT03992898).ResultsMultivariate analysis indicated that an elevated TSH level was a highly significant predictor for 30-day survival (HR = 0.743, 95% CI: 0.629-0.878, P < 0.001) and 90-day survival (HR = 0.807, 95% CI: 0.717-0.909, P < 0.001). The AUROC of TSH level for 30-day and 90-day mortality were 0.655 and 0.620, respectively, with the same best cut-off values of 0.261 µIU/mL. Log-rank test showed that the group with higher TSH level had higher 30-day (78.5%, 95% CI: 76.1%-80.9% vs. 56.9%, 95% CI: 53.4%-60.4%; P < 0.001) and 90-day survival rate (61.5%, 95% CI: 58.6%-64.4% vs. 42.8%, 95% CI: 39.3%-46.3%; P < 0.001). Similar findings were observed in subgroups analysis. After adjusting for age and other risk factors, the higher level of TSH remained associated with 30-day survival (HR = 0.602, 95% CI: 0.502-0.721, P < 0.001) and 90-day survival (HR = 0.704, 95% CI, 0.609-0.814, P < 0.001).ConclusionsSerum TSH level significantly correlate with HBV-related ACLF patients' survival and may be of value for predicting 30-day and 90-day survival of patients with HBV-related ACLF.
