BACKGROUND/AIMS: Cirrhotic patients with liver stiffness measurement (LSM) <20 kPa and platelet count ≥150×109/L (Baveno VI criteria), otherwise spleen stiffness measurement (SSM) ≤40 kPa (Baveno VI-SSM criteria) can avoid endoscopy screening; however, no prospective data for their hepatic outcomes. METHODS: Compensated cirrhosis with HBV were prospectively enrolled from April 2019 to April 2022 and followed until July 2023. All patients underwent LSM, SSM and esophagogastroduodenoscopy assessment. RESULTS: Among 1,224 patients enrolled with median follow-up of 30 months (interquartile range, 21-42), the incidence of decompensation was greater in 560 patients with unfavored Baveno VI criteria (0.5 vs. 20.4 per 1,000 person-years, P=0.0004) than that in 664 patients with favored Baveno VI-SSM criteria. The Baveno VI-SSM model identified more patients (54.2%) as low-risk for decompensation than Baveno VII-SSM model (single cutoff) (48.4%, P=0.004) and than Baveno VI criteria (34.6%, P<0.0001) did. Patients with high-risk varices diagnosed via endoscopy following Baveno VI-SSM model assessment had greater probability of decompensation compared to those identified by the Baveno VII-SSM model (single cutoff) (42.8 vs. 21.1 per 1,000 person-years, P=0.0088). Additionally, among the 493 patients who underwent endoscopic re-assessment, 242 patients with favored Baveno VI-SSM criteria had much lower incidence of EV progression (2.6 vs. 99.5 per 1,000 person-years, P=0.0004) and lower risk of decompensation compared to 140 patients with unfavored Baveno VI-SSM model (0 vs. 34.2 per 1,000 person-years, P=0.0256). CONCLUSION: Baveno VI-SSM model could identify HBV-related cirrhosis patients at low risk of decompensation, which was greatly improved upon Baveno VI-SSM reassessment.
BACKGROUND AND AIMS: The Baveno VII consensus recommends spleen stiffness measurement (SSM) for the detection of clinically significant portal hypertension (CSPH) in patients with compensated advanced chronic liver disease (cACLD). We aimed to evaluate the performance of SSM-based algorithms. METHODS: Consecutive cACLD individuals who underwent hepatic venous pressure gradient measurement, liver stiffness measurement (LSM), and SSM measured with the dedicated 100-Hz probe by vibration-controlled transient elastography were prospectively enrolled. RESULTS: From July 2021 to August 2024, a total of 395 patients were screened, and 185 cACLD cases were enrolled, of which 101 patients had CSPH. An SSM > 50 kPa demonstrated a positive predictive value (PPV) of 98.0% and a specificity of 98.8% for ruling in CSPH, correctly identifying 47.5% (48/101) of CSPH cases. Sensitivity analysis revealed that in 60 patients with aetiology removal or suppression, SSM > 50 kPa achieved both a PPV and specificity of 100%. Among the 125 patients with ongoing aetiologies, the PPV and specificity were 96.4% and 98.3%, respectively. Across HBV (with or without viral suppression) and non-HBV subgroups, the PPV and specificity consistently exceeded 90%. In decision curve analysis, SSM > 50 kPa provided the highest net benefit compared with other elastography-based algorithms when threshold probabilities exceeded 0.8. CONCLUSIONS: We prospectively validated that SSM > 50 kPa, measured using the spleen-dedicated probe, is sufficient for identifying CSPH in individuals with cACLD. TRIAL REGISTRATION: NCT04820166.
