BACKGROUND/AIMS: The utility of Baveno-VII criteria of clinically significant portal hypertension (CSPH) to predict decompensation in compensated advanced chronic liver disease (cACLD) patient needs validation. We aim to validate the performance of CSPH criteria to predict the risk of decompensation in an international real-world cohort of cACLD patients.
cACLD patients were stratified into three categories (CSPH excluded, grey zone, and CSPH). The risks of decompensation across different CSPH categories were estimated using competing risk regression for clustered data, with death and hepatocellular carcinoma as competing events. The performance of "treating definite CSPH" strategy to prevent decompensation using non-selective beta-blocker (NSBB) was compared against other strategies in decision curve analysis.
One thousand one hundred fifty-nine cACLD patients (36.8% had CSPH) were included; 7.2% experienced decompensation over a median follow-up of 40 months. Non-invasive assessment of CSPH predicts a 5-fold higher risk of liver decompensation in cACLD patients (subdistribution hazard ratio, 5.5; 95% confidence interval, 4.0-7.4). "Probable CSPH" is suboptimal to predict decompensation risk in cACLD patients. CSPH exclusion criteria reliably exclude cACLD patients at risk of decompensation, regardless of etiology. Among the grey zone, the decompensation risk was negligible among viral-related cACLD, but was substantially higher among the non-viral cACLD group. Decision curve analysis showed that "treating definite CSPH" strategy is superior to "treating all varices" or "treating probable CSPH" strategy to prevent decompensation using NSBB.
Non-invasive assessment of CSPH may stratify decompensation risk and the need for NSBB in cACLD patients.
背景/目的:Baveno-VII 临床显著门静脉高压(CSPH)标准预测代偿期慢性肝病(cACLD)患者失代偿的效用需要验证。我们旨在验证 CSPH 标准在国际真实世界的 cACLD 患者队列中预测失代偿风险的性能。
cACLD 患者分为三组(排除 CSPH、灰色地带和 CSPH)。使用聚类数据竞争风险回归估计不同 CSPH 类别中的失代偿风险,以死亡和肝细胞癌为竞争事件。在决策曲线分析中,比较了使用非选择性β受体阻滞剂(NSBB)治疗明确 CSPH 策略预防失代偿与其他策略的效果。
纳入 1159 例 cACLD 患者(36.8%存在 CSPH);中位随访 40 个月时,7.2%的患者发生失代偿。CSPH 的非侵入性评估可预测 cACLD 患者肝脏失代偿的风险增加 5 倍(亚分布危险比,5.5;95%置信区间,4.0-7.4)。“可能存在 CSPH”对预测 cACLD 患者的失代偿风险并不理想。CSPH 排除标准可可靠地排除有失代偿风险的 cACLD 患者,而与病因无关。在灰色地带,病毒性 cACLD 患者的失代偿风险可以忽略不计,但非病毒性 cACLD 患者的风险显著更高。决策曲线分析表明,与“治疗所有静脉曲张”或“治疗可能存在的 CSPH”策略相比,使用 NSBB 治疗明确 CSPH 策略可更有效地预防失代偿。
CSPH 的非侵入性评估可分层预测 cACLD 患者的失代偿风险和 NSBB 的需求。
