One Week of Esomeprazole Triple Therapy vs. 1 Week of Omeprazole Triple Therapy Plus 3 Weeks of Omeprazole for Duodenal Ulcer Healding in <Emphasis Type="Italic">Helicobacter pylori</Emphasis>-Positive Patients

In this randomized, double-blind, multicenter study, H. pylori-positive patients with an active duodenal ulcer (DU) received esomeprazole, 20 mg twice daily (bid), or omeprazole, 20 mg bid, with amoxicillin, 1000 mg bid, and clarithromycin, 500 mg bid, for 1 week (EAC and OAC, respectively). Patients received an additional 3 weeks of either placebo or omeprazole, 20 mg once daily (od), in the EAC and OAC groups, respectively. The intent-to-treat population included 374 patients (EAC, 186; OAC, 188). Four-week DU healing rates were similar in the EAC+placebo and OAC+omeprazole groups: 74% and 76%, respectively. DU healing rates at 8 weeks were 87% for EAC+placebo and 88% for OAC+omeprazole. H. pylori eradication rates were 75% and 79% for EAC and OAC, respectively. Both regimens were well tolerated. A 1-week regimen of esomeprazole-based H. pylori eradication triple therapy was as effective for DU healing and eradication of H. pylori as omeprazole-based triple therapy followed by an additional 3 weeks of monotherapy.     

One week of treatment with esomeprazole-based triple therapy eradicates Helicobacter pylori and heals patients with duodenal ulcer disease.

BACKGROUND: Proton pump inhibitor (PPI) monotherapy is commonly continued for 3 weeks after Helicobacter pylori eradication with PPI-based triple therapy regimens to ensure duodenal ulcer (DU) healing. This randomized, double-blind, multicentre study evaluated whether only 1 week of triple therapy with the new PPI esomeprazole was sufficient to ensure high rates of ulcer healing and H. pylori eradication. METHODS: A total of 446 H. pylori-positive patients with active DU received twice daily treatment with esomeprazole 20 mg (n = 222) or omeprazole 20 mg (n = 224) in combination with amoxicillin 1 g and clarithromycin 500 mg for 1 week (EAC and OAC, respectively). Patients in the OAC group then received 3 weeks' monotherapy with omeprazole 20 mg once daily; those treated with EAC received placebo. Ulcer healing was assessed by endoscopy on completion of therapy and H. pylori status was assessed by (13)C-urea breath testing and histology 4-6 weeks later. RESULTS: Ulcer healing rates (95% CI) for intention-to-treat and per-protocol populations were: EAC + placebo 91% (87-95%) and 94% (90-97%); OAC + omeprazole 92% (88-95%) and 96% (92-98%). Corresponding H. pylori eradication rates were: EAC + placebo 86% (81-90%) and 89% (84-93%); OAC + omeprazole 88% (83-92%) and 90% (85-93%). Both eradication regimens were well tolerated, and patient compliance was high. CONCLUSIONS: A 1-week regimen of esomeprazole-based triple therapy is sufficient for DU healing and H. pylori eradication in patients with DU disease.

Role of anti-secretory treatment in addition to Helicobacter pylori eradication triple therapy in the treatment of peptic ulcer]

BACKGROUND/AIMS: It is not clear whether the anti-secretory therapy should be continued for symptomatic relief and ulcer healing before or after the eradication of H. pylori in patients with peptic ulcer disease. The aim of this study was to evaluate the effectiveness of additional anti-secretory therapy before or after H. pylori eradication in peptic ulcer disease. METHODS: Thirty eight patients with H. pylori-positive active peptic ulcer were included. Patients were randomly allocated into 3 groups; standard 1-week triple therapy followed by omeprazole (20 mg, qd) for 3 weeks (group A), standard 1-week triple therapy only (group B), and omeprazole (20 mg, qd) for 3 weeks followed by 1-week triple therapy (group C). Endoscopy with the rapid urease test and histology for H. pylori was performed 4-8 weeks after the completion of treatment. The symptom was scored by a visual analog scale. RESULTS: Of the 38 patients, 10 were excluded from the per-protocol analysis of this study. The H. pylori eradication rates were 87.5% (group A), 80.0% (group B) and 90.0% (group C) respectively. The peptic ulcer healing rates were 100% in group A, 70.0% in group B, and 90.0% in group C. There was no difference in H. pylori eradication rates and ulcer healing rates among three groups (p>0.05). Symptom score differences between pre-treatment and post-treatment group were not significantly different (p>0.05). CONCLUSIONS: The standard one week triple therapy with or without 3-weeks anti-secretory treatment with omeprazole before or after the therapy does not affect H. pylori eradication rates, peptic ulcer healing rates, and symptom score improvement.     

Twice-daily, 10-day triple therapy with omeprazole, amoxicillin, and clarithromycin for Helicobacter pylori eradication in duodenal ulcer disease: results of three multicenter, double-blind, United States trials

Objective: We assessed the safety and efficacy of 10-day twice-daily triple therapy for Helicobacter pylori ( H. pylori ) in three double-blind, controlled trials in patients with duodenal ulcer disease.
Methods: H. pylori -infected patients with one or more duodenal ulcer(s) at endoscopy (studies 1, 2) or with a documented duodenal ulcer history and no duodenal ulcer or erosions at endoscopy (study 3) were randomly assigned to 10-day courses of omeprazole 20 mg b.i.d . plus amoxicillin 1 g b.i.d . plus clarithromycin 500 mg b.i.d . (OAC) or placebo plus amoxicillin 1 g b.i.d . plus clarithromycin 500 mg b.i.d . (AC). In studies 1 and 2, patients received an additional 18 days of omeprazole 20 mg q.d . (OAC group) or placebo (AC group). Endoscopy was repeated 4 wk after therapy in studies 1 and 2 and 4–6 wk after therapy in study 3. At baseline, H. pylori was diagnosed by CLOtest plus histology, or by culture. Eradication was defined as no positive biopsy test and two or more negative tests. Patients were defined as compliant if they took 75% or more of each study drug and missed ≤ 3 consecutive days of the 10-day therapy.
Results: Intent-to-treat populations of the three studies combined were 241 patients for OAC and 266 for AC. Of all OAC patients combined, 2% stopped study medications due to adverse events, and 93% were compliant. Per-protocol cure rates were 78% to 90% (all studies combined, 84%) for OAC vs 33% to 45% (combined, 39%) for AC (   p < 0.001  , OAC vs AC); intent-to-treat eradication rates were 69% to 83% (combined, 75%) for OAC vs 32% to 37% (combined, 35%) for AC; (   p < 0.001  , OAC vs AC).
Conclusion: Rigorously designed studies indicate that 10 days of twice-daily triple therapy with omeprazole, amoxicillin, and clarithromycin achieves per-protocol eradication rates of approximately 80% to 90% in the U.S.     

Eradication therapy with rabeprazole versus omeprazole in the treatment of active duodenal ulcer

BACKGROUND: Rabeprazole has been demonstrated to be a potent antisecretory agent and has been shown to be clinically effective in the treatment of acid-related diseases. AIMS: It was to determine the efficacy of rabeprazole at 20 and 40 mg in addition to amoxicillin and clarithromycin in the treatment of active Helicobacter pylori-positive duodenal ulcers compared with omeprazole 40 mg. PATIENTS AND METHODS: One hundred and twenty-seven patients were randomised into three treatment groups: 40 patients were treated with rabeprazole 40 mg daily, 42 patients with rabeprazole 20 mg daily and 45 patients with omeprazole 40 mg daily for 10 days. All patients received amoxicillin 1 g twice a day and clarithromycin 500 mg twice a day for 5 days. All patients were re-assessed at least 4 weeks after the end of the treatment. RESULTS: According to the intention-to-treat (ITT) protocol, ulcer healing was observed in 90% of patients in the rabeprazole 40 group, in 85.7% in the rabeprazole 20 group and in 93.3% in the omeprazole 40 group. We observed H. pylori eradication in 90% ITT in the rabeprazole 40 group, in 80.9% ITT in the rabeprazole 20 group and in 88.8% ITT in the omeprazole 40 group. Statistical analysis did not show significant differences among the three groups.

目的评价基于莫西沙星的三联疗法作为幽门螺杆菌（Hp）感染二线治疗的疗效和安全性。方法将74例经标准三联疗法治疗失败的Hp感染患者随机分为A组和B组,两组均为37例。A组给予口服雷贝拉唑10mg＋阿莫西林1g＋莫西沙星400mg,均为2次/d;B组给予口服雷贝拉唑10mg（2次/d）＋枸橼酸铋钾300mg（4次/d）＋甲硝唑（400mg,3次/d）＋四环素（500mg,3次/d）。两组均治疗7d,疗程结束后4周复查~（14）C尿素呼气试验。结果按意向治疗分析A组和B组的Hp根除率分别为78.4%和56.8%,差异有统计学意义（P=0.047）;按符合方案分析A组和B组的Hp根除率分别为85.3%和70.0%,差异无统计学意义（P=0.140）。两组的不良反应率分别为10.8%和27.0%,差异无统计学意义（P=0.075）。结论含莫西沙星的三联方案优于含铋剂的四联方案,是一种疗效好且安全性高的Hp根除二线疗法。     

雷贝拉唑钠治疗消化性溃疡的多中心临床研究

目的：评价雷贝拉唑钠10mg/d在消化性溃疡治疗中的疗效及安全性,并与奥美拉唑20mg/d进行比较。方法：采用随机开放对照临床研究,患者随机进入雷贝拉唑钠组（治疗组）或奥美拉唑组（对照组）,共有137例病人完成治疗,其中治疗组70例,对照组67例;治疗组口服雷贝拉唑钠片每次10mg,每日1次;对照组口服奥美拉唑胶囊每次20mg,每日1次。十二指肠球部溃疡疗程为4周,胃溃疡为6周。结果：两组治疗前后疼痛症状的改善及疼痛时间的消失,差异无显著性（P＞0．05）。十二指肠溃疡病人中,治疗组痊愈率和愈合率分别为38．5％和98．1％,对照组分别为26．0％和94．0％,两组间差异无显著性（P均＞0．05）。胃溃疡 病人中,治疗组痊愈率和愈合率分别为50．0％和100．0％,对照组分别为35．3％和94．1％,两组间差异无显著性（P均＞0．05）。整个试验过程中,治疗组和对照组不良反应率分别为4．3％和4．5％,两组间不良反应发生率相似（P＝1．000）。结论：雷贝拉唑钠10mg能安全、有效地治疗消化性溃疡,其缓解疼痛、促进溃疡愈合的疗效与奥美拉唑20mg相当。
