Tetracycline, metronidazole and amoxicillin-metronidazole combinations in proton pump inhibitor-based triple therapies are equally effective as alternative therapies against Helicobacter pylori infection

Background: A proton pump inhibitor (PPI)‐based triple therapy with clarithromycin (CAM) and amoxicillin (AMPC) is now a standard regimen for Helicobacter pylori (HP) eradication in Japan. However, the CAM‐resistant rate has increased recently and alternative therapies are sorely needed. Therefore the aim of the present study was to evaluate the effectiveness and safety of the PPI–tetracycline (TC)–metronidazole (MNZ) regimen (the PTM regimen) as an alternative therapy in comparison with the PPI–AMPC–MNZ (PAM) regimen. Methods: Sixty‐four HP‐positive patients visiting the HP‐eradication clinic in Tokai University Hospital from July 1998 to March 2003 were treated with either PTM or PAM as alternative therapies. The HP eradication was assessed by urea breath test (UBT), HP stool antigen test, or HP culture method more than 2 months after completion of the treatments. The drug resistances against CAM, AMPC, TC, and MNZ were assessed by the agar dilution method. Results: Fifty‐six patients (26 PTM and 30 PAM) completed medication and evaluation of the eradication. The eradication rates of PTM were 82.8% (24/29) and 92.3% (24/26), while those of PAM were 74.3% (26/35) and 89.7% (26/29) by intention‐to‐treat and per‐protocol analysis, respectively. The differences between the regimens were not statistically significant. There were no severe adverse effects observed in either of the regimens. The drug‐resistance analyses showed 15 CAM‐ and one MNZ‐resistant cases but no TC or AMPC resistance in the available 25 samples. Conclusion: The PTM and PAM regimens were equally effective and safe as alternative HP eradication therapies. And PTM would be particularly useful in penicillin allergy cases.

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.

Two new treatment regimens for Helicobacter pylori eradication: a randomised study

BACKGROUND: Several studies have found a fairly low Helicobacter pylori eradication rate using a standard 7-day triple therapy in Italy. Recently, two new therapeutic schedules have been proposed with an eradication rate higher than 90%. This study compared the efficacy of these two treatment regimens. PATIENTS AND METHODS: A total of 131 patients with Helicobacter pylori infection and either non-ulcer dyspepsia (73 patients] or peptic ulcer (58 patients) were enrolled. Helicobacter pylori infection was assessed by rapid urease test and histology on gastric biopsies. Patients were randomised to receive either a 5-day course of ranitidine bismuth citrate 400 mg bid, clarithromycin 500 bid, and tinidazole 500 bid, or a 10-day course of omeprazole 20 mg bid plus amoxycillin 1 g bid for the first 5 days, and omeprazole 20 mg bid, clarithromycin 500 mg bid and tinidazole 500 mg bid for the remaining 5 days. Eradication was assessed by endoscopy 4-6 weeks after therapy. RESULTS: Overall, 4 patients (2 for each treatment group) were lost to follow-up. Helicobacter pylori eradication rates were 67.2% (95% confidence interval: 55.7-78.7) and 65.2% (95% confidence interval: 53.7-76.6) at per protocol and intention-to-treat analyses, respectively, after the 5-day regimen, and 96.8% (95% confidence interval: 92.5-100) and 93.8% (95% confidence interval: 88-99.7) after the 10-day regimen (p<0.05). Both treatments were well tolerated, and no major side-effects were reported. CONCLUSIONS: The 5-day regimen gave disappointing results, while the eradication rate after the 10-day regimen was very high.     

我国幽门螺杆菌感染处理共识推荐的铋剂四联方案根除率分析

背景:随着幽门螺杆菌(Hp)耐药率的上升及其所导致的标准三联疗法根除率的下降,铋剂四联方案成为我国最新共识推荐的Hp感染根除治疗方案。目的:评价各共识推荐铋剂四联方案的根除治疗效果,为高效、价廉的根除治疗方案的选择提供参考。方法:检索CNKI、万方、维普数据库,纳入我国2011-2013年间公开发表,采用共识推荐的铋剂四联方案根除Hp感染的临床试验类文献。提取文献资料,根据Graham等提出的Hp根除率分级系统,对根除率进行分析。结果:共166篇文献入选,包括Hp感染根除试验192项。在全国范围内,含阿莫西林方案的根除率大部分可以接受,其中PAFB(PPI+阿莫西林+呋喃唑酮+铋剂)方案取得优异根除率(≥95%)的可能性最高。在华东和中南地区,相应的适宜根除治疗方案分别为PACB(PPI+阿莫西林+克拉霉素+铋剂)和PAFB方案。适宜疗程为14 d。结论:在各共识推荐铋剂四联方案中,PAFB方案具有明显的效益和成本优势。在全国范围内,非阿莫西林过敏个体行Hp感染根除治疗宜优先选用PAFB方案,建议疗程为14 d。     

Are twelve days of omeprazole, amoxicillin and clarithromycin better than six days for treating H. pylori infection in peptic ulcer and in non-ulcer dyspepsia?

BACKGROUND/AIMS: To evaluate whether omeprazole, amoxicillin and clarithromycin for 12 days is more effective for Helicobacter pylori eradication than the same regimen for only 6 days; and to verify whether these eradication regimens are more effective in peptic ulcer disease than in non-ulcer dyspepsia. METHODOLOGY: We studied 411 patients in whom a gastroscopy was carried out due to symptoms related to the upper gastrointestinal tract and who were diagnosed with duodenal ulcer (175 patients, 43%), gastric ulcer (42 patients, 10%), or non-ulcer dyspepsia (194 patients, 47%), and concomitant infection by H. pylori. At endoscopy, biopsies were obtained for rapid urease test, and a 13C-urea breath test was carried out. Urea breath test was repeated four weeks after completing eradication treatment with 1) omeprazole (20 mg b.i.d.), amoxicillin (1 g b.i.d.) and clarithromycin (500 mg b.i.d.) for six days (239 patients), or 2) the same regimen for 12 days (172 patients). RESULTS: H. pylori eradication was achieved in 73.6% (95% CI, 68-79%) of the patients treated during 6 days, and in 84.3% (79-90%) of those receiving 12 days of therapy (P < 0.01). The overall eradication rate with both regimens (6 plus 12 days), respectively in patients with duodenal ulcer, gastric ulcer and non-ulcer dyspepsia, was 84.6% (79-90%), 75.6% (61-86%), and 72.8% (67-79%) (P < 0.01 when comparing duodenal ulcer vs. non-ulcer dyspepsia). Twelve-day regimen was more effective than 6-day regimen only in non-ulcer dyspepsia (62% vs. 83%, P < 0.01), but not in duodenal or gastric ulcer. In the multivariate analysis the duration (6 vs. 12 days) of eradication therapy (odds ratio: 2.2; 1.3-3.7) and the type of disease (duodenal ulcer vs. non-ulcer dyspepsia; odds ratio: 2.3; 1.3-3.8) were the only variables which influenced on H. pylori eradication efficacy (chi 2 model, 17; P < 0.001). CONCLUSIONS: Efficacy with omeprazole-amoxicillin-clarithromycin regimen in patients with duodenal ulcer is higher than in those patients with non-ulcer dyspepsia. The increase of H. pylori eradication rate by 21% in our non-ulcer dyspepsia patients justifies the prolongation from 6 to 12 days of omeprazole-amoxicillin-clarithromycin therapy, whilst the increase of cure rates in duodenal or gastric ulcer patients with a 12-day therapy would not be cost-effective.     

Efficacy of Different Helicobacter pylori Eradication Regimens in Patients Affected by Insulin-Dependent Diabetes Mellitus

Background: Patients with insulin-dependent diabetes mellitus (IDDM) are often affected by chronic infections; antibiotic absorption, however, may be influenced by the disease. H. pylori eradication appears to be reduced in IDDM patients. The aim of the study was to evaluate the efficacy of the most common H. pylori eradication regimens in a population of IDDM-infected patients. Methods: One hundred and seventy-two IDDM patients were evaluated. H. pylori infection was assessed through the 13C-urea breath test. Infected patients were randomly assigned to three different standard 7-day eradication regimens: 1) amoxicillin, clarithromycin, pantoprazole; 2) tinidazole, clarithromycin, ranitidine bismuth citrate; or 3) tinidazole, clarithromycin, pantoprazole. Patients in whom eradication was not successful in the first cycle were subsequently submitted to a 7-day therapy with tinidazole, tetracycline, bismuth, and pantoprazole. Results: Thirty-seven per cent of IDDM patients were infected. None of the triple therapies used provided an eradication higher than 62%. Conversely, the quadruple regimen was successful in 88% of the patients. Ten per cent of the subjects undergoing the triple therapies showed minor side effects, without significant differences among groups, whereas side effects occurred in 25% of the patients treated with the quadruple therapy (P &lt; 0.05). Conclusions: IDDM patients show a low H. pylori eradication rate with a standard triple therapy regardless of the regimen utilized, the dosage and/or the duration of the therapy used appearing not to be sufficient to eradicate the infection efficiently. The use of a quadruple regimen leads to the cure of a large percentage of the infected patients in whom the eradication was unsuccessful in the first therapy, although it is accompanied by a greater incidence of minor side effects.

CONCLUSIONS: IDDM patients show a low H. pylori eradication rate with a standard triple therapy regardless of the regimen utilized, the dosage and/or the duration of the therapy used appearing not to be sufficient to eradicate the infection efficiently. The use of a quadruple regimen leads to the cure of a large percentage of the infected patients in whom the eradication was unsuccessful in the first therapy, although it is accompanied by a greater incidence of minor side effects.
