We report here the final analysis of a multicentre randomized, single-blind trial of propranolol for prophylaxis of first bleeding in cirrhosis. One hundred and seventy-four consecutive patients with large esophageal varices were randomly assigned to either propranolol in doses reducing the resting heart rate by 25% (85 patients) or to a placebo (vitamin K: 89 patients). Three were lost to follow-up and 26 had to be withdrawn from propranolol because of side effects (n = 23) or low compliance (n = 3). The cumulative value over 42 months of patients free of bleeding was 74% (95% confidence interval = 85%-63%) in the propranolol and 59% (95% CI = 79%-43%) in the control group and the corresponding survival figures were 51% (95% CI = 63%-39%) and 59% (95% CI = 75%-43%): neither of the differences was significant. A retrospective analysis according to the presence of ascites at randomization showed that in the subset without ascites the proportion of patients free of bleeding was significantly higher in the propranolol group than in the control group (83% vs. 61%; 95% CI = 97%-69% and 78%-44%, respectively; P = 0.028); this difference was even more evident in the ascites-free period (94% vs. 58%; 95% CI = 100%-86% and 76%-40%, respectively; P = 0.002). No differences were found in patients with ascites at randomization. Survival was not significantly affected by treatment in any subgroup, although it was shorter in the ascitic patients given propranolol than in controls (33% vs. 49%; 95% CI = 51%-15% and 71%-27%, respectively; P = 0.07).(ABSTRACT TRUNCATED AT 250 WORDS)
我们在此报告一项关于普萘洛尔预防肝硬化首次出血的多中心随机单盲试验的最终分析。174例连续性大食管静脉曲张患者被随机分为两组,一组给予能使静息心率降低25%的剂量的普萘洛尔(85例患者),另一组给予安慰剂(维生素K:89例患者)。3例失访,26例因副作用(n = 23)或依从性差(n = 3)而不得不停用普萘洛尔。普萘洛尔组42个月无出血患者的累积比例为74%(95%置信区间 = 85% - 63%),对照组为59%(95%置信区间 = 79% - 43%),相应的生存数据分别为51%(95%置信区间 = 63% - 39%)和59%(95%置信区间 = 75% - 43%):两者差异均无统计学意义。根据随机分组时腹水的情况进行的回顾性分析显示,在无腹水亚组中,普萘洛尔组无出血患者的比例显著高于对照组(分别为83%对61%;95%置信区间分别为97% - 69%和78% - 44%;P = 0.028);在无腹水期这种差异更为明显(分别为94%对58%;95%置信区间分别为100% - 86%和76% - 40%;P = 0.002)。随机分组时有腹水的患者未发现差异。尽管给予普萘洛尔的腹水患者的生存期比对照组短(分别为33%对49%;95%置信区间分别为51% - 15%和71% - 27%;P = 0.07),但在任何亚组中治疗对生存均无显著影响。(摘要截断于250字)
