BACKGROUND/AIMS: In acute variceal bleeding (AVB) hepatic venous pressure gradient (HVPG) is associated with prognosis. However, this has not been studied in patients receiving the currently recommended therapy. We evaluate here the performance of early HVPG measurement as a predictor of treatment failure in patients with acute variceal bleeding managed with the current standard treatment and whether clinical variables might be of similar predictive accuracy.
We included 117 patients with AVB in whom HVPG was measured within 48 h of admission. The main endpoint was 5-day failure, a composite of uncontrolled bleeding, early rebleeding or death within 5 days.
Eighteen patients (15%) had 5-day failure. Multivariate analysis identified three variables independently associated with 5-day failure: HVPG 20, systolic blood pressure at admission <100 mmHg and non-alcoholic cause of cirrhosis. The discriminative capacity of this model was good (c statistic: 0.79). When only clinical variables were included in the analysis, Child-Pugh class, systolic blood pressure at admission and etiology were the independent predictors. This model had also a good discriminative ability (c statistic: 0.80).
HVPG independently predicts short-term prognosis in patients with acute variceal bleeding treated with pharmacologic and endoscopic therapy, but similar predictive accuracy can be achieved using only simple clinical variables that have universal applicability.
背景/目的:在急性静脉曲张出血(AVB)中,肝静脉压力梯度(HVPG)与预后相关。然而,目前尚未在接受当前推荐治疗的患者中对此进行研究。我们在此评估早期测量HVPG作为接受当前标准治疗的急性静脉曲张出血患者治疗失败预测指标的性能,以及临床变量是否可能具有相似的预测准确性。
我们纳入了117例AVB患者,这些患者在入院后48小时内测量了HVPG。主要终点是5天内治疗失败,定义为5天内出现无法控制的出血、早期再出血或死亡的综合情况。
18例患者(15%)出现5天内治疗失败。多变量分析确定了三个与5天内治疗失败独立相关的变量:HVPG≥20、入院时收缩压<100 mmHg和非酒精性肝硬化病因。该模型的判别能力良好(c统计量:0.79)。当分析中仅纳入临床变量时,Child-Pugh分级、入院时收缩压和病因是独立预测因素。该模型也具有良好的判别能力(c统计量:0.80)。
HVPG可独立预测接受药物和内镜治疗的急性静脉曲张出血患者的短期预后,但仅使用具有普遍适用性的简单临床变量也可达到相似的预测准确性。
