Efficacy of omeprazole and amoxicillin with either clarithromycin or metronidazole on eradication of Helicobacter pylori in Chinese peptic ulcer patients

AIM: One-week triple therapy with proton pump inhibitors, clarithromycin and amoxicillin has recently been proposed as the first-line treatment for Helicobacter pylori (H pylori) infection; however, data regarding the effects of this regimen in China are scarce. The aim of this prospective and randomized study was to compare the efficacy of clarithromycin and metronidazole when they were combined with omeprazole and amoxicillin on eradication of H pylori and ulcer healing in Chinese peptic ulcer patients. METHODS: A total of 103 subjects with Hpylori-positive peptic ulcer were randomly divided into two groups, and accepted triple therapy with omeprazole 20 mg, amoxicillin 1 000 mg and either clarithromycin 500 mg (OAC group, n = 58) or metronidazole 400 mg (0AM group, n - 45). All drugs were given twice daily for 7 d. Patients with active peptic ulcer were treated with omeprazole 20 mg daily for 2-4 wk after anti-H pylori therapy. Six to eight weeks after omeprazole therapy, all patients underwent endoscopies and four biopsies (two from the antrum and two others from the corpus of stomach) were taken for rapid urease test and histological analysis (with modified Giemsa staining) to examine H pylori. Successful eradication was defined as negative results from both examination methods. RESULTS: One hundred patients completed the entire course of therapy and returned for follow-up. The eradication rate of H pylori for the per-protocol analysis was 89.3% (50/56) in OAC group and 84.1% (37/44) in 0AM group. Based on the intention-to-treat analysis, the eradication rate of H pylori was 86.2% (50/58) in OAC group and 82.2% (37/45) in 0AM group. There were no significant differences in eradication rates between the two groups on either analysis. The active ulcer-healing rate was 96.7% (29/30) in OAC group and 100% (21/21) in 0AM group (per-protocol analysis, P>0.05). Six patients in OAC group (10.3%) and five in OAM group (11.1%) reported adverse events (P>0.05). CONCLUSION: One-week triple therapy with omeprazole and amoxicillin in combination with either clarithromycin or metronidazole is effective for the eradication of H pylori. The therapeutic regimen comprising metronidazole with low cost, good compliance and mild adverse events may offer a good choice for the treatment of peptic ulcers associated with H pylori infection in China.

Omeprazole 40 mg o.m. Combined with Amoxycillin Alone or with Amoxycillin and Metronidazole in the Eradication of Helicobacter pylori

Objectives: Our objectives were to determine the effect of dual therapy with omeprazole and amoxicillin and of triple therapy with omeprazole, amoxicillin, and metronidazole in the eradication of Helicobacter pylori (HP) and to study the long-term results of eradication in these patients. Methods: A prospective, randomized, controlled trial was performed. Patients who were recruited had unequivocal evidence of HP infection based on culture, histology, rapid urease test, and Gram's stain of a tissue smear. Eradication was defined as the absence of bacteria in all tests performed on both corpus and antral biopsies. Results: The infection was eradicated in 15 of 19 (78.9%) patients randomized to receive dual therapy and in 19 of 22 (86.4%) patients who received triple therapy. We followed the course of 30 patients in whom HP had been eradicated for a prolonged term (up to 12 months). All remained clear of HP. Twenty-five of 28 patients (89.3%) with duodenal ulcers in whom HP was successfully eradicated remained healed at 12 months. Fewer side effects were reported among patients who received the dual therapy. Conclusions: Combination therapy with omeprazole and amoxicillin with or without metronidazole is effective in the eradication of HP. In particular, the dual therapy regimen with amoxicillin is not only effective but is also well tolerated by patients.     

Amoxicillin plus omeprazole versus triple therapy for eradication of Helicobacter pylori in duodenal ulcer disease: a prospective, randomized, and controlled study.

Treatment with amoxicillin and omeprazole resulted in encouraging Helicobacter pylori eradication rates in pilot studies that included medium term follow up. These results were evaluated in a prospective, randomised and controlled study. Forty patients with active duodenal ulcer disease and H pylori colonisation of the gastric mucosa were randomly assigned to receive either omeprazole (20 mg twice daily) and amoxicillin suspension (500 mg four times daily) for two weeks (group I) or bismuth subsalicylate (600 mg three times daily), metronidazole (400 mg three times daily), tetracycline (500 mg three times daily), and ranitidine (300 mg in the evening) for two weeks (group II). Study medication was followed in both groups by a four week treatment course with 300 mg ranitidine up to the final examination. One patient from each group was lost to follow up. H pylori was eradicated in 78.9% of group I and 84.2% of group II (p = 1.00). All ulcers in patients on omeprazole plus amoxicillin healed but in the triple treatment group four patients had residual peptic lesions after six weeks (ulcer healing rate: 78.9%, p = 0.11). Complete pain relief occurred after a median duration of 1 day in group I and of 6 days in group II (p = 0.03). There were no major complications in either group but minor side effects were more frequently recorded in patients on triple therapy (63.2% v 15.8%, p < 0.01). In conclusion, two weeks of treatment with omeprazole plus amoxicillin is as good as triple therapy plus ranitidine in eradicating H pylori but seems better with regard to safety, pain relief, and ulcer healing. Thus, amoxicillin plus omeprazole should be recommended as the treatment of choice in eradicating H pylori in patients with duodenal ulcer disease.     

The impact of Helicobacter pylori eradication on peptic ulcer healing

Objective: Current literature was reviewed analyzing the outcome of peptic ulcer healing in relation to the results of the posttherapeutic Helicobacter pylori (HP) status.
Methods: Literature was reviewed along with an analysis of 60 studies, comprising a total of 4329 patients.
Results: Successful Helicobacter pylori eradication was found to induce a better response in peptic ulcer healing, regardless of diagnosis: gastric ulcer 88% vs 73% (odds ratio [OR] 2.7,   p < 0.01  ), duodenal ulcer 95% vs 76% (OR 5.6,   p < 0.0001  ), and peptic ulcer 95% vs 76% (OR 6.6,   p < 0.0001  ), for patients having their HP infection successfully cured versus those remaining HP-positive, respectively (Fisher's exact test). For all evaluated time points (≤ 6, 7–8, and 10–12 wk after beginning treatment), HP-negative patients had higher healing rates than HP-positive patients (95% vs 82%, 94% vs 69%, and 96% vs 78% with corresponding OR of 4.2, 6.5, and 7.4, all   p < 0.0001  , Fisher's exact test). The use of concomitant acid suppression therapy during initial HP eradication provided a benefit on peptic ulcer healing only for patients with persistent HP infection (improved healing rates of 78% vs 67%; otherwise rates were 94–96%). Likewise, prolonged acid inhibition in HP treatment failures after the initial HP treatment phase resulted in 7–20% improved healing rates, whereas patients becoming HP-negative did not profit.
Conclusion: Successful HP eradication therapy accelerates peptic ulcer healing even without concomitant acid suppression.     

A pilot study to evaluate a new combination therapy for gastric ulcer: Helicobacter pylori eradication therapy followed by gastroprotective treatment with rebamipide

Background and Aim: Controversies remain over the need for antiulcer treatment following 1‐week eradication triple therapy for Helicobacter pylori‐positive peptic ulcers. The usefulness of combination therapy for gastric ulcers in Japanese patients, which consists of H. pylori eradication followed by gastroprotective therapy with rebamipide, was therefore evaluated. Methods: The study was conducted in 52 H. pylori‐positive patients with an endoscopically‐proven open gastric ulcer. All patients received 1‐week triple therapy (lansoprazole, amoxicillin and clarithromycin) followed by 7‐week rebamipide therapy. After completion of the combination therapy, all patients underwent evaluation of ulcer healing by endoscopy, gastric ulcer symptoms and H. pylori eradication by rapid urease test and ¹³C‐urea breath test. Results: The ulcer healing rates were 85.7% (36/42) at 8 weeks, 83.3% (30/36) in eradicated patients and 100% (6/6) in non‐eradicated patients. The overall gastrointestinal symptom‐free rate improved from 19.0% at baseline to 88.1% at 8 weeks. H. pylori was effectively eradicated in 85.7% (36/42) of patients. Conclusions: The results suggested that the combination therapy for open gastric ulcer was safe, well‐tolerated and effective. However, data from a double‐blind placebo‐controlled study is necessary to confirm these findings.     

Efficacy of the dosing regimen of pantoprazole 40 mg, amoxicillin 1000 mg and clarithromycin 500 mg, twice daily for 7 days, in the eradication of Helicobacter pylori in patients with peptic ulcer

AIM: This is an open label, multicenter trial to determine the efficacy of the association of pantoprazole, clarithromycin and amoxicillin to eradicate Helicobacter pylori in patients with peptic ulcer. MATERIAL AND METHODS: Seventy-one patients (36 females, 35 males, average age 41.9 years) from three Brazilian university centers (located in the cities of Belo Horizonte and Porto Alegre), with peptic ulcers confirmed by endoscopy, and infections by H. pylori proven by at least two diagnostic testings were admitted in the trial. An association of pantoprazole 40 mg, clarithromycin 500 mg and amoxicillin 1.0 g was administered to patients twice daily for 7 days. RESULTS: By the end of treatment all patients were examined for digestive symptoms, presence of adverse events, and treatment adherence. Sixty days after the end of the treatment a new endoscopy with biopsies and respiratory function testing with 13C-urea breath test was performed in order to determine the eradication rates of that microorganism. Patients showing negative results at least in the 13C-urea breath test and in one other test (urease or histology) were considered H. pylori-negative. By the end of the trial, 60/69 (87%, CI 95% = 78.9-94.8) patients had the H. pylori eradicated in the per protocol analysis and 60/71 (84.5%, CI 95% = 76-92.9) in the intention-to-treat analysis. One patient was withdrawn from the trial due to a diarrhea. Twelve (16.9%) patients showed adverse symptoms that were deemed as mild symptoms. CONCLUSION: Our conclusion is that the association of pantoprazole, amoxicillin and clarithromycin administered during 7 days is an effective and well-tolerated alternative as regards the eradication of H. pylori in patients with peptic ulcer in Brazil.
