We conducted a prospective, randomized single-blind trial of propranolol for the prevention of recurrent variceal bleeding. Seventy-nine patients shown to have variceal hemorrhage at endoscopy were included in the study within 72 hr following diagnosis. Fifty-seven patients had alcoholic cirrhosis, 10 cryptogenic cirrhosis, 6 posthepatitic cirrhosis, 4 biliary cirrhosis, 1 portal vein thrombosis without cirrhosis and 1 idiopathic portal hypertension. The severity of liver disease at inclusion was assessed according to the Pugh modification of the Child-Turcotte classification: 9 (11%) had Class A; 41 (52%) Class B, and 29 (37%) Class C disease. Patients were randomly assigned by sealed envelope to the propranolol group (42 patients) or the placebo group (37 patients). Propranolol dosage was titrated in order to produce plasma concentrations of propranolol of 50 to 150 ng per ml. beta-blockade was also confirmed by isoproterenol testing. The cumulative percentages of patients free of rebleeding 1 and 2 years after inclusion were 31 and 21% in the propranolol group, and 25 and 17% in the placebo group; both differences were not significant. Cumulative 1 and 2 years survival were also comparable: 64 and 54% in the propranolol group vs. 70 and 63% in the placebo group. There was no evidence for a therapeutic effect of propranolol after adjusting for potential confounding variables by multiple logistic regression. We conclude that propranolol is not effective for the prevention of variceal rebleeding, when administered early following the initial bleed, in cirrhotics unselected with respect to the severity of the liver disease.
我们进行了一项前瞻性、随机单盲试验,以研究普萘洛尔预防静脉曲张再出血的效果。79例经内镜检查显示有静脉曲张出血的患者在诊断后72小时内纳入本研究。其中57例为酒精性肝硬化,10例为隐源性肝硬化,6例为肝炎后肝硬化,4例为胆汁性肝硬化,1例为无肝硬化的门静脉血栓形成,1例为特发性门静脉高压。根据Child-Turcotte分类法的Pugh改良版评估入组时的肝病严重程度:9例(11%)为A级;41例(52%)为B级,29例(37%)为C级。患者通过密封信封随机分配至普萘洛尔组(42例)或安慰剂组(37例)。滴定普萘洛尔剂量以使血浆普萘洛尔浓度达到每毫升50至150纳克。通过异丙肾上腺素试验也证实了β受体阻滞。入组后1年和2年无再出血患者的累积百分比在普萘洛尔组分别为31%和21%,在安慰剂组分别为25%和17%;两组差异均无统计学意义。1年和2年的累积生存率也相当:普萘洛尔组为64%和54%,安慰剂组为70%和63%。通过多因素logistic回归调整潜在混杂变量后,没有证据表明普萘洛尔有治疗效果。我们得出结论,对于未根据肝病严重程度进行选择的肝硬化患者,在首次出血后早期给予普萘洛尔对预防静脉曲张再出血无效。
