Prophylactic treatment of variceal bleeding in cirrhotic patients with beta-blockers is effective in only some patients. Our aim was to determine whether the response of the hepatic venous pressure gradient (HVPG) to the intravenous administration of propranolol predicts the response after chronic oral propranolol treatment.
We included prospectively cirrhotic patients with esophageal varices under primary prophylaxis (PP) and secondary prophylaxis (SP). The HVPG was measured at baseline and after a propranolol bolus (0.15 mg/kg intravenous). A patient was considered a good-responder if HVPG decreased to 12 mmHg or 20% from baseline. Patients then received oral propranolol (heart rate titrated). Poor-responders under SP were also included in a variceal band ligation program. After at least 3 months, a second hemodynamic study was conducted.
Fifty-six patients were included (36 SP and 20 PP). Response rate was similar (32.1 and 41.9%, P=0.7) and the Pearson's correlation coefficient was 0.61 (P=0.001). In 81.4% patients, the first study predicted the response status of the second. Six patients rebled on follow-up between the studies, all of them were poor responders to intravenous propranolol.
A single hemodynamic study using intravenous propranolol seems to predict chronic response to propranolol.
在肝硬化患者中使用β受体阻滞剂预防静脉曲张出血仅对部分患者有效。我们的目的是确定肝静脉压力梯度(HVPG)对普萘洛尔静脉注射的反应是否可预测慢性口服普萘洛尔治疗的反应。
我们前瞻性纳入了正在接受原发性预防(PP)和二级预防(SP)的食管静脉曲张的肝硬化患者。在基线时和普萘洛尔推注(0.15 mg/kg 静脉内)后测量 HVPG。如果 HVPG 从基线下降至 12 mmHg 或 20%,则认为患者是良好反应者。然后,患者接受普萘洛尔口服治疗(根据心率调整剂量)。SP 下的不良反应者也被纳入静脉曲张带结扎计划。至少 3 个月后,进行第二次血流动力学研究。
共纳入 56 例患者(SP 36 例,PP 20 例)。反应率相似(32.1%和 41.9%,P=0.7),Pearson 相关系数为 0.61(P=0.001)。在 81.4%的患者中,第一次研究预测了第二次研究的反应状态。两次研究之间有 6 例患者出现随访再出血,他们均为静脉内普萘洛尔不良反应者。
单次使用静脉内普萘洛尔的血流动力学研究似乎可预测普萘洛尔的慢性反应。
