BACKGROUNDThe Baveno VI criteria for predicting esophageal varices, i.e., liver stiffness measurement (LSM) < 20 kPa and platelet (PLT) count > 150 × 109/L, identify patients who can safely avoid gastroscopy screening. However, they require further refinement.AIMTo evaluate the utility of LSM and serum markers of liver fibrosis in ruling out high-risk varices (HRV) in patients who do not meet Baveno VI criteria.METHODSData from 132 patients with hepatitis B virus (HBV)-related compensated liver cirrhosis who did not meet the Baveno VI criteria were retrospectively reviewed. MedCalc 15.8 was used to calculate receiver operating characteristic (ROC) curves, and the accuracy of LSM, PLT count, aspartate aminotransferase (AST)-to-PLT ratio index, Fibrosis-4, and the Lok index in predicting HRV were evaluated according to the area under each ROC curve (AUROC). The utility of LSM, PLT, and serum markers of liver fibrosis stratified by alanine transaminase (ALT) and total bilirubin (TBil) levels was evaluated for ruling out HRV.RESULTSIn all patients who did not meet the Baveno VI criteria, the independent risk factors for HRV were LSM and ALT. Only the AUROC of Lok index was above 0.7 for predicting HRV, and at a cutoff value of 0.4531 it could further spare 24.2% of gastroscopies without missing HRVs. The prevalence of HRV was significantly lower in patients with ALT or TBil ≥ 2 upper limit of normal (ULN) (14.3%) than in patients with both ALT and TBil < 2 ULN (34.1%) (P = 0.018). In the 41 patients with ALT and TBil < 2 ULN, LSM had an AUROC for predicting HRV of 0.821. LSM < 20.6 kPa spared 39.0% of gastroscopies without missing HRVs. In the 91 patients with ALT or TBiL ≥ 2 ULN, the Lok index and PLT had AUROCs of 0.814 and 0.741, respectively. Lok index ≤ 0.5596 or PLT > 100 × 109/L further spared 39.6% and 43.9% of gastroscopies, respectively, without missing HRVs.CONCLUSIONIn HBV-related compensated cirrhosis patients who do not meet Baveno VI criteria, the LSM, PLT, or Lok index cutoff stratified by ALT and TBil accurately identifies more patients without HRV.
Background: The aim of this study was to explore the effects of endoplasmic reticulum (ER) stress on hepatitis B virus (HBV) replication and the antiviral effect of entecavir (ETV).Methods: Thapsigargin (TG) and stearic acid (SA) were used to induce ER stress in HepG2.2.15 cells and HepAD38 cells that contained an integrated HBV genome, while ETV was used to inhibit HBV replication. The expression levels of glucose-regulated protein 78 (GRP78) and phosphorylated eukaryotic translation initiation factor 2 subunit alpha (p-eIF2α) were measured by western blotting. Intracellular HBV DNA was determined by qPCR; HBsAg by western blotting; HBV RNA by real-time RT-qPCR; HBsAg and HBeAg in supernatants by enzyme-linked immunosorbent assay (ELISA); and HBV DNA in supernatants by qPCR.Results: TG and SA induced ER stress in HepG2.2.15 cells and HepAD38 cells from 12 to 48 h post treatment. However, 4-phenylbutyric acid (PBA) partly alleviated the TG-induced ER stress. Moreover, TG inhibited HBsAg, HBeAg, and HBV DNA secretion from 12 to 48 h, while different concentrations of SA inhibited HBsAg and HBV DNA secretion at 48 h. TG promoted intracellular HBV DNA and HBsAg accumulation and the transcription of the HBV 3.5-kb mRNA and S mRNA. PBA treatment restored the secretion of HBsAg and HBV DNA. Finally, ER stress accelerated extracellular HBV DNA clearance but delayed intracellular HBV DNA clearance after ETV treatment.Conclusions: Hepatocyte ER stress promoted intracellular HBV DNA and HBsAg accumulation by inhibiting their secretion. Our study also suggested that hepatocyte ER stress delayed intracellular HBV DNA clearance after ETV treatment.
Background/purpose Associations between the disturbances in glucose homeostasis and prognosis in patients with hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF) remain unclear. This study was conducted to investigate the clinical characteristics of disturbances in glucose homeostasis and their associations with 90-day mortality in patients with HBV-related ACLF. Methods Ninety-six patients with HBV-related ACLF without pre-existing diabetes were prospectively included. Glucose abnormalities were diagnosed based on fasting plasma glucose and oral glucose tolerance test results on admission and during follow-up. Homeostasis model assessment was used to establish insulin resistance (HOMA2-IR), insulin sensitivity (HOMA2-IS) and HOMA2-β-cell function (HOMA2-β). Multivariate Cox proportional hazards analysis was used to identify independent risk factors for death within 90 days after admission. Results Among 96 patients with ACLF, 51 (53.1%) had diabetes, 29 (30.2%) had impaired glucose tolerance (IGT), and 17 (17.7%) had hypoglycemia. Patients with diabetes had significantly lower levels of HOMA2-β than did patients with normal glucose tolerance. Of 22 patients with diabetes or IGT and without anti-hyperglycemic treatment, 8 (36.4%) exhibited regression of their glucose metabolism disorders after a follow-up of 32.8 ± 28.8 days, and higher platelet levels were associated with regression. Twenty-five patients (25.0%) with ACLF died of liver failure within 90 days. Diabetes [odds ratio (OR) 3.601, 95% confidence interval (CI) 1.342–9.661] and age (OR 1.045, 95% CI 1.010–1.082) were the independent risk factors associated with mortality. Conclusion Impaired pancreatic β-cell function is related to diabetes development, and diabetes is associated with high mortality in patients with chronic HBV-related ACLF.

In the past decade, numerous studies have evaluated the roles of noninvasive methods for diagnosing or excluding varices and high-risk varices in patients with liver cirrhosis. The Baveno VI criteria recommend the use of a simple algorithm based on a liver stiffness measurement < 20 kPa through transient elastography and a platelet count > 150 × 10 9 / L for ruling out high-risk varices in patients with compensated advanced chronic liver disease. A large number of studies have validated the clinical usefulness of Baveno VI criteria for excluding high-risk varices. Several strategies have been proposed to refine the Baveno VI criteria; however, currently there is no review to summarize the diagnostic accuracy and limitations of the Baveno VI criteria after extensive validation. In this review, we summarize the diagnostic accuracy and limitations of the Baveno VI criteria after extensive validation. We also discuss methods to refine these criteria.
