Abstract

To assess the effectiveness of propranolol in the prevention of initial variceal hemorrhage, a double-blind, randomized trial was carried out in three centers. Patients with cirrhosis (78% alcoholic), hepatic venous pressure gradients greater than 12 mm Hg and endoscopically proven esophageal varices were randomly assigned to propranolol (51 patients) or placebo (51 patients). Of the 102 patients, 58% were Child's class A, 34% were Child's class B and 8% were Child's class C. Daily dosage was determined by the administration of progressively increasing doses of propranolol with the hepatic vein catheter in place to achieve a 25% decrease in hepatic venous pressure gradient, a decrease in hepatic venous pressure gradient to less than 12 mm Hg or a decrease in resting heart rate to less than 55 beats/min. During a mean follow-up period of 16.3 mo, 11 patients in the placebo group (22%) bled from esophageal varices compared with 2 in the propranolol group (4%) during a mean period of 17.1 mo (p less than 0.01). Three additional patients (6%) in the placebo group bled from portal hypertensive gastropathy compared with none in the propranolol group. Propranolol appeared effective in preventing bleeding from large varices. Eleven deaths (22%) occurred in the placebo group compared with eight deaths (16%) in the propranolol group (NS). The mean dose of propranolol was 132 mg/day, and the median dose was 80 mg/day. Using a compliance index (pill count, clinic attendance, alcohol and propranolol levels and alcohol history), 81% of the propranolol patients and 77% of the placebo patients were considered compliant. Complications severe enough to require cessation of therapy occurred in eight patients (16%) in the propranolol group and four in the placebo group (8%) (NS). We conclude that propranolol effectively prevents the first variceal hemorrhage in patients with alcoholic cirrhosis and large esophageal varices but does not improve survival.

摘要

为评估普萘洛尔预防初次静脉曲张出血的有效性,在三个中心开展了一项双盲随机试验。入选患者为肝硬化患者(78%为酒精性肝硬化),肝静脉压力梯度大于12 mmHg且经内镜证实有食管静脉曲张,将其随机分为普萘洛尔组(51例)和安慰剂组(51例)。102例患者中,58%为Child's A级,34%为Child's B级,8%为Child's C级。每日剂量通过在放置肝静脉导管的情况下逐步增加普萘洛尔剂量来确定,以实现肝静脉压力梯度降低25%,或肝静脉压力梯度降至小于12 mmHg,或静息心率降至小于55次/分钟。在平均16.3个月的随访期内,安慰剂组有11例患者(22%)发生食管静脉曲张出血,而普萘洛尔组在平均17.1个月的观察期内有2例患者(4%)出血(P<0.01)。安慰剂组另有3例患者(6%)发生门静脉高压性胃病出血,而普萘洛尔组无此情况。普萘洛尔似乎对预防大静脉曲张出血有效。安慰剂组有11例患者死亡(22%),普萘洛尔组有8例患者死亡(16%)(无显著性差异)。普萘洛尔的平均剂量为132 mg/天,中位剂量为80 mg/天。根据依从性指标(药片计数、门诊就诊情况、酒精和普萘洛尔水平以及饮酒史),81%的普萘洛尔组患者和77%的安慰剂组患者被认为依从性良好。普萘洛尔组有8例患者(16%)出现严重到需要停药的并发症,安慰剂组有4例患者(8%)出现此类并发症(无显著性差异)。我们得出结论,普萘洛尔可有效预防酒精性肝硬化和大食管静脉曲张患者的首次静脉曲张出血,但不能提高生存率。
