Background: The eradication rates of Helicobacter pylori (H. pylori) with standard treatments are decreasing worldwide as in Greece. Studies with new antibiotic combinations are needed to find better methods of eradication. Therefore, the aim of this study was to evaluate efficacy and tolerability of a 10‐day, four‐drug, three‐antibiotic, nonbismuth–containing concomitant regimen. Materials and Methods: This is a prospective, open‐label, multicenter study that included 131 patients infected with H. pylori. All patients were diagnosed with peptic ulcer disease or nonulcer dyspepsia by endoscopy. H. pylori infection was established by at least two positive tests among rapid urease test, gastric histology, and 13C‐urea breath test. For 10 days, all patients received esomeprazole 40 mg, amoxycillin 1000 mg, clarithromycin 500 mg, and metronidazole 500 mg, all b.d. eradication was assessed with 13C urea breath test 8 weeks after the start of treatment. Intention‐to‐treat and per‐protocol eradication rates were determined. Results: One hundred and twenty‐seven of the 131 patients completed the study. At intention‐to‐treat analysis, the eradication rate was 91.6% (95% confidence interval (CI), 85.5–95.7%). For the per‐protocol analysis, the eradication rate was 94.5% (95% CI, 89–97.8%). Adverse events were noted in 42 of 131 (32.1%); drug compliance was excellent with 96.9% of the patients taking more than 90% of the prescribed medication. Conclusion: A 10‐day concomitant regimen appears to be an effective, safe, and well‐tolerated treatment option for first‐line H. pylori eradication in Greece. 相似文献

Background
The efficacy of Helicobacter pylori (H. pylori) eradication has steadily declined, primarily because of antibiotic resistance. This study aimed to evaluate the efficacy and safety of furazolidone eradication therapies as initial treatments for H. pylori infection.Methods
A national, multicenter, open‐label, randomized controlled trial was performed at 16 sites across 13 provinces in China to evaluate the efficacy and safety of furazolidone‐containing therapies for H. pylori infection. Treatment naïve patients were randomly assigned to: esomeprazole 20 mg, bismuth 220 mg, amoxicillin 1000 mg, and furazolidone 100 mg twice daily for 10 and 7 days (FAB 10 and FAB 7; the same therapy without bismuth (FA 10 and FA 7). The primary and secondary outcomes were the eradication rate and regimen safety, respectively. Treatment success was assessed by the 13C urea breath test at least 4 weeks after treatment completion.Results
Overall, according to intention‐to‐treat (ITT) analysis, the eradication rates for FAB 10 and FAB 7 were 86.6% (95% confidence interval [CI], 79.9%‐93.2%) and 83.6% (95% CI, 76.3%‐90.9%) and for FA 10 and FA 7 were 82.4% (95% CI, 74.9%‐89.8%) and 77.6% (95% CI, 69.4%‐85.8%), respectively. According to per‐protocol analysis, the overall eradication rates for FAB 10 and FAB 7 were 94.7% (95% CI, 90.3%‐99.1%) and 90.8% (95% CI, 85.1%‐96.5%) and for FA 10 and FA 7 were 90.6% (95% CI, 84.9%‐96.3%) and 85.1% (95% CI, 78.2%‐92.1%), respectively. The overall prevalence of side effects was 8.1%.Conclusions
Furazolidone‐containing therapies, particularly the tested 10‐day quadruple therapy, exhibited satisfactory efficacy and safety. This 10‐day quadruple therapy represents a promising initial treatment strategy for Chinese patients. 相似文献8.
Impact of furazolidone-based quadruple therapy for eradication of Helicobacter pylori after previous treatment failures 总被引:11,自引:0,他引:11
Background. One week of quadruple therapy including metronidazole is recommended for Helicobacter pylori treatment failures after first line therapy regardless of resistance status. This study investigated whether a quadruple regimen containing furazolidone could be effective as a third‐line (salvage) therapy. Methods. All patients with previous H. pylori treatment failure after a clarithromycin‐metronidazole ± amoxicillin combination plus acid suppression were given lansoprazole 30 mg twice a day (bid), tripotassiumdicitratobismuthate 240 mg bid, tetracycline 1 g bid, metronidazole 400 mg (PPI‐B‐T‐M) three times a day (tid) for 1 week. In the case of treatment failure with this second‐line therapy, the same regimen was applied for 1 week except for using furazolidone 200 mg bid (PPI‐B‐T‐F) instead of metronidazole (sequential study design). Results. Eighteen consecutive patients were treated with PPI‐B‐T‐M. Eleven of those 18 remained H. pylori positive (38.9% cured). Pretherapeutic metronidazole resistance was associated with a lower probability of eradication success (10% vs. 75%, p= .04). Ten of these 11 patients agreed to be retreated by PPI‐B‐T‐F. Final cure of H. pylori with PPI‐B‐T‐F was achieved in 9/10 patients (90%) nonresponsive to PPI‐B‐T‐M. Conclusions. In the presence of metronidazole resistance, PPI‐B‐T‐M as a recommended second‐line therapy by the Maastricht consensus conference achieved unacceptable low cure rates in our metronidazole pretreated population. In this population, metronidazole based second‐line quadruple therapy may be best suited in case of a metronidazole‐free first line‐regimen (e.g. PPI‐clarithromycin‐amoxicillin) or a low prevalence of metronidazole resistance. Furazolidone in the PPI‐B‐T‐F combination does not have a cross‐resistance potential to metronidazole and is a promising salvage option after a failed PPI‐B‐T‐M regimen. 相似文献

BACKGROUND AND AIMS: Although triple combination therapy containing a proton pump inhibitor (PPI) and two antibiotics is considered as a standard regimen for the first-line anti-Helicobacter pylori treatment, there are still debates on the ideal duration of treatment. The aim of this study was to compare the efficacies of 7-day and 14-day PPI-containing triple therapy. MATERIALS AND METHODS: This study was performed in a randomized, multicenter, prospective manner. After upper gastrointestinal endoscopy, H. pylori-infected patients with a gastric ulcer and/or a duodenal ulcer were randomly assigned to a PAC7 group (omeprazole 20 mg or equivalent dose of other PPIs, amoxicillin 1000 mg, and clarithromycin 500 mg twice daily for 7 days) or to a PAC14 group (the same regimen as the PAC7 group but for 14 days). H. pylori status was evaluated by (13)C urea breath test 5 weeks after anti-ulcer treatment completion. RESULTS: A total of 598 patients were enrolled; 337 were randomized to the PAC7 group and 261 to the PAC14 group. The two groups were comparable in terms of baseline characteristics. The eradication rates of the PAC7 group were not inferior to those of the PAC14 group in both intention-to-treat analysis (71.2% vs. 75.5%) and per-protocol analysis (83.6% vs. 86.6%). Incidences of adverse events were comparable. CONCLUSIONS: Although the 7-day PPI-containing triple anti-H. pylori therapy is not inferior to the 14-day therapy, neither treatment duration provides acceptable eradication rate reaching 90% in per-protocol analysis. New combination regimen with higher efficacy should be developed as a first-line eradication therapy for H. pylori in Korea. 相似文献

Low efficacy rate of moxifloxacin-containing Helicobacter pylori eradication treatment: in an observational study in a Turkish population 总被引:3,自引:0,他引:3
BACKGROUND: Standard triple therapy for Helicobacter pylori has an eradication rate of about 50% in Turkey. It may be due to an increased resistance of H. pylori to antibiotics. Therefore, we aimed to investigate the effectiveness of a new second-generation fluoroquinolone, moxifloxacin-containing triple therapy in H. pylori eradication. MATERIAL AND METHODS: This is an open-label, prospective, single-center, pilot study. We studied 71 dyspeptic patients infected with H. pylori diagnosed by both histology and rapid urease test. Out of 71 dyspeptic patients, 64 had non-ulcer dyspepsia and seven had peptic ulcer. Patients received pantoprazole (40 mg b.i.d.) plus moxifloxacin (400 mg/day) and amoxicillin (1000 mg b.i.d.) for 14 days. Eradication was assessed 4 weeks after completing the therapy by histology and rapid urease test. Per-protocol and intention-to-treat eradication rates were determined. RESULTS: The eradication rate was 42.2% for the intention-to-treat analysis and 47.6% for the per-protocol analysis. Of all patients included in the study, 29.5% had side-effects and only 2.8% of the patients discontinued the treatment because of side-effects. Most of the complications were mild and self-limiting. CONCLUSION: Triple therapy with pantoprazole, moxifloxacin, and amoxicillin for 14 days yielded unacceptably low eradication rates. However, using tests of susceptibility to antibiotics, further studies with larger sample sizes are needed to judge these eradication rates of moxifloxacin containing eradication treatment. 相似文献

BACKGROUND: The long-term benefit of Helicobacter pylori eradication treatment that includes metronidazole on peptic ulcer disease in Japan is unclear. We investigated the rate of H. pylori re-infection and ulcer relapse after H. pylori eradication. MATERIALS AND METHODS: A total of 266 patients with endoscopically confirmed peptic ulcer disease and H. pylori infection were treated with triple therapy of omeprazole 40 mg (20 mg b.i.d.), clarithromycin 800 mg (400 mg b.i.d.), and tinidazole 1000 mg (500 mg b.i.d.) for 7 days. Endoscopy with gastric biopsy was performed before and 1 month, 6 months, 1.5 years, and 3.5 years after therapy. H. pylori status was determined by H. pylori culture, rapid urease test, and histopathology. 13C-urea breath test was done at 6 months after eradication therapy. Treatment was deemed successful when all tests were negative at 6 months after therapy by endoscopic biopsy. RESULTS: Successful H. pylori eradication was achieved in 262/266 (98.5%) patients with peptic ulcer. Total relapse of peptic ulcer occurred in 8/262 (3%) patients after eradication, with 3/262 (1.1%) occurring within 1.5 years after treatment and 5/262 (1.9%) within 3.5 years. All relapsed patients were found to be H. pylori-positive at the time of relapse. Of the 262 patients who experienced eradication, 20 (7.6%) were subsequently re-infected, six (2.3%) within 1.5 years and 14 (5.3%) within 3.5 years. CONCLUSION: Triple therapy with omeprazole, clarithromycin, and tinidazole (OCT) is useful for H. pylori eradication in Japan, but there is an appreciable re-infection rate in this population. 相似文献

Aim. To test whether vitamin C and E supplements to triple therapy can improve the Helicobacter pylori eradication rate and gastric inflammation. Methods. A total of 104 H. pylori‐infected patients were randomized to receive: either lansoprazole, amoxicillin, and metronidazole twice daily for 1 week (triple‐only group) or lansoprazole, amoxicillin, metronidazole plus vitamin C (250 mg) and vitamin E (200 mg) twice daily for 1 week, followed immediately by vitamin C and E once daily for 6 consecutive weeks (triple‐plus‐vitamin group). Eight weeks after the completion of triple therapy, patients were assessed for the effectiveness of H. pylori eradication. The severity of gastric inflammation in histology was assessed for the acute and chronic inflammation scores. Results. Intention‐to‐treat and per‐protocol eradication rates were 59.1% and 64.4% in the triple‐only group, and 40% and 44% in the triple‐plus‐vitamin group. In the patients infected with metronidazole susceptible isolates, the triple‐only group had a higher intention‐to‐treat eradication rate than those in the triple‐plus‐vitamin group (80% vs. 53.1%, p < .01). However, for the metronidazole resistance isolates, the intention‐to‐treat eradication rates between the two groups were not different (26.3% vs. 21.7%, p = NS). The improvements of both acute and chronic inflammation scores in histology were not different between the two groups. Conclusion. Adding vitamin C and E to triple therapy cannot improve the H. pylori eradication rate and gastric inflammation. For patients with metronidazole susceptible strain infection, adding these vitamins may even reduce the eradication rate of triple therapy. 相似文献
