The use of intravenous proton-pump inhibitors (PPIs) has shown to reduce recurrent bleeding and improve patient outcome after endoscopic hemostasis on patients with peptic ulcer. However, the efficacy of oral PPI is uncertain. Studies from Asia indicated that even oral PPI can achieve the same therapeutic effect. This study is designed to compare the efficacy of high-dose intravenous PPI to oral PPI in preventing recurrent bleeding after endoscopic hemostasis.
This is a single-center, randomized-controlled, double-blind, and double-dummy study. Patients had Forrest IA/IB or IIA/IIB peptic ulcer bleeding and received endoscopic hemostasis before recruitment into the study. They were randomized to receive either (i) esomeprazole IV bolus at a dose of 80 mg plus infusion at 8 mg/h for 72 h and oral placebo every 12 h (IVP group), or (ii) IV placebo bolus plus infusion for 72 h and high-dose oral esomeprazole at a dose of 40 mg every 12 h (ORP group). Patients were followed up for 30 days after index bleeding. The primary end point was defined as the 30-day recurrent bleeding after successful endoscopic hemostasis.
A total of 118 patients were randomized to the IVP group and 126 to the ORP group in this study. In all, 39.8% in the IVP and 42.9% in the ORP group used non-steroidal anti-inflammatory drug and/or aspirin before bleeding. In the IVP group (vs. ORP), Forrest IA represented 1.7% (5.6%), IB 41.5% (38.1%), IIA 52.5% (50.8%), and IIB 4.2% (5.6%). Recurrent bleeding in 30 days was reported in 7.7% of patients in the IVP group and 6.4% of patients in the ORP group, and the difference of recurrent bleeding was -1.3% (95% CI: -7.7%, 5.1%). There was no difference in blood transfusion, repeated endoscopic therapy, and hospital stay between the two groups.
High-dose oral esomeprazole at 40 mg BID may be considered as a useful alternative to IV bolus plus infusion of esomeprazole in the management of ulcer bleeding in patients who are not candidates for high-dose IV infusion. However, as this study was stopped prematurely and was not designed as an equivalency trial, a much larger study would be necessary to document whether there is equivalency or non-inferiority of the two treatments in a heterogeneous patient population.
静脉注射质子泵抑制剂 (PPI) 的使用已被证明可以减少消化性溃疡内镜止血后再出血的风险并改善患者的预后。然而,口服 PPI 的疗效尚不确定。亚洲的研究表明,即使是口服 PPI 也可以达到相同的治疗效果。本研究旨在比较高剂量静脉注射 PPI 与口服 PPI 在预防内镜止血后再出血方面的疗效。
这是一项单中心、随机对照、双盲、双模拟研究。患者存在 Forrest IA/IB 或 IIA/IIB 型消化性溃疡出血,并在招募入组前接受了内镜止血。他们被随机分为两组:(i)静脉注射艾司奥美拉唑 80mg 推注,随后以 8mg/h 的速度输注 72 小时,每 12 小时口服安慰剂(IVP 组),或(ii)静脉注射安慰剂推注和输注 72 小时,然后每 12 小时口服高剂量艾司奥美拉唑 40mg(ORP 组)。患者在指数性出血后接受 30 天的随访。主要终点定义为内镜止血成功后 30 天内再出血。
本研究共纳入 118 例患者随机分配至 IVP 组,126 例患者随机分配至 ORP 组。IVP 组和 ORP 组分别有 39.8%和 42.9%的患者在出血前使用非甾体抗炎药和/或阿司匹林。IVP 组(vs. ORP 组)中 Forrest IA 型占 1.7%(5.6%),IB 型占 41.5%(38.1%),IIA 型占 52.5%(50.8%),IIB 型占 4.2%(5.6%)。IVP 组和 ORP 组在 30 天内再出血的患者比例分别为 7.7%和 6.4%,再出血差异为-1.3%(95%CI:-7.7%,5.1%)。两组间输血、重复内镜治疗和住院时间无差异。
对于不适合高剂量静脉输注的溃疡出血患者,高剂量口服艾司奥美拉唑(40mg,bid)可作为静脉注射艾司奥美拉唑推注和输注的替代方案。然而,由于本研究提前停止且并非设计为等效性试验,因此需要进行更大规模的研究来证实两种治疗方案在异质患者人群中的等效性或非劣效性。
