Acute variceal hemorrhage is a major decompensating event in patients with cirrhosis and is associated with high 6-week mortality risk. Many prognostic models based on clinical and laboratory parameters have been developed to risk stratify patients on index bleeding presentation, including those based on the Model for End-Stage Liver Disease (MELD) and Child-Turcotte-Pugh (CTP). However, consensus on model performance remains unclear.
Using a large US multicenter cohort of hospitalized patients with cirrhosis who presented with acute variceal hemorrhage, this study evaluates, recalibrates, and compares liver severity index-based models, including the more recent MELD 3.0 model, to investigate their predictive performance on 6-week mortality. Models were also recalibrated and externally validated using additional external centers.
All recalibrated MELD-based and CTP-based models had excellent discrimination to identify patients at higher risk for 6-week mortality on initial presentation. The recalibrated CTP score model maintained the best calibration and performance within the validation cohort. Patients with low CTP scores (Class A, score 5-6) were strongly associated with < 5% mortality, while high CTP score (Class C, score > 9) were associated with > 20% mortality.
Use of liver severity index-based models accurately predict 6-week mortality risk for patients admitted to the hospital with acute variceal hemorrhage and supports the utilization of these models in future clinical trials as well as their use in clinical practice.
急性静脉曲张出血是肝硬化患者失代偿的主要事件,与 6 周高死亡率风险相关。许多基于临床和实验室参数的预后模型已被开发出来,用于对指数出血表现的患者进行风险分层,包括基于终末期肝病模型(MELD)和 Child-Turcotte-Pugh(CTP)的模型。然而,对于模型性能的共识仍不清楚。
本研究使用美国多中心住院肝硬化患者的大型队列,这些患者因急性静脉曲张出血而就诊,评估、重新校准和比较了基于肝严重程度指数的模型,包括最近的 MELD 3.0 模型,以调查它们在 6 周死亡率方面的预测性能。还使用其他外部中心重新校准和外部验证了模型。
所有重新校准的 MELD 基础和 CTP 基础模型在初始表现时对识别 6 周死亡率较高的患者均具有极好的区分能力。重新校准的 CTP 评分模型在验证队列中保持最佳校准和性能。CTP 评分低的患者(A级,评分 5-6)与<5%的死亡率强烈相关,而 CTP 评分高的患者(C 级,评分>9)与>20%的死亡率相关。
使用基于肝严重程度指数的模型可以准确预测因急性静脉曲张出血而住院的患者 6 周死亡率风险,支持在未来临床试验中使用这些模型,并在临床实践中使用这些模型。
