Helicobacter pylori eradication with either 7-day or 10-day triple therapies, and with a 10-day sequential regimen.

BACKGROUND: Helicobacter pylori eradication rates achieved by standard seven-day triple therapies are decreasing in several countries, while a novel 10-day sequential regimen has achieved a very high success rate. A longer 10-day triple therapy, similar to the sequential regimen, was tested to see whether it could achieve a better infection cure rate. METHODS: Patients with nonulcer dyspepsia and H pylori infection were randomly assigned to one of the following three therapies: esomeprazole 20 mg, clarithromycin 500 mg and amoxycillin 1 g for seven days or 10 days, or a 10-day sequential regimen including esomeprazole 20 mg plus amoxycillin 1 g for five days and esomeprazole 20 mg, clarithromycin 500 mg and tinidazole 500 mg for the remaining five days. All drugs were given twice daily. H pylori eradication was checked four to six weeks after treatment by using a 13C-urea breath test. RESULTS: Overall, 213 patients were enrolled. H pylori eradication was achieved in 75.7% and 77.9%, in 81.7% and 84.1%, and in 94.4% and 97.1% of patients following seven-day or 10-day triple therapy and the 10-day sequential regimen, at intention-to-treat and per protocol analyses, respectively. The eradication rate following the sequential regimen was higher than either seven-day (P=0.002) or 10-day triple therapy (P=0.02), while no significant difference emerged between the latter two regimens (P=0.6). CONCLUSIONS: The 10-day sequential regimen was significantly more effective than both triple regimens, while 10-day triple therapy failed to significantly increase the H pylori eradication rate achieved by the standard seven-day regimen.     

A 10-day levofloxacin-based therapy in patients with resistant Helicobacter pylori infection: a controlled trial.

BACKGROUND & AIMS: Antibiotic resistance is a major issue in anti- Helicobacter pylori treatment. This study was aimed at assessing the efficacy of 2 therapies in patients with resistant H pylori infection. METHODS: Patients who had failed 1 or more eradication regimens underwent upper gastrointestinal endoscopy and 2 antral and 2 corpus biopsy specimens were taken for histology and culture. Metronidazole, clarithromycin, and amoxicillin resistance were determined by E-test. Patients were randomly assigned to 2 therapies: 1 group received pantoprazole 40 mg, amoxicillin 1 g, levofloxacin 250 mg, all twice daily for 10 days, and the other group was treated with omeprazole 20 mg twice daily for the first week and omeprazole 20 mg twice daily, tetracycline 250 mg 4 times daily, metronidazole 500 mg twice daily, and bismuth subcitrate 240 mg twice daily for the second week. Therapeutic success was evaluated by 13C urea breath test after 4 weeks of treatment. RESULTS: We enrolled 44 patients in the levofloxacin-based regimen and 46 patients in the quadruple therapy. The former was successful in 31 of 44 (70%; 95% confidence interval: 53-87) and the latter in 17 of 46 (37%; 95% confidence interval: 23-47) patients, using intention-to-treat (ITT) analysis (P < .001). The rates of H pylori resistance to metronidazole, clarithromycin, and amoxicillin were 46%, 12%, and 0%, respectively. Resistance to both metronidazole and clarithromycin was found in 10% of cases. CONCLUSIONS: Triple therapy containing levofloxacin was better than quadruple therapy. The 70% success rate observed indicates that 10 days of pantoprazole, amoxicillin, and levofloxacin should be considered in patients who had failed 1 or more eradication regimens.     

Vitamin C inhibits corpus gastritis in Helicobacter pylori-infected patients during acid-suppressive therapy

BACKGROUND: Previous studies have shown that gastric acid suppression worsens corpus gastritis in Helicobacter pylori (H. pylori)-positive patients. We evaluated the effect of acid-suppressive therapy and vitamin C on H. pylori-associated gastritis. METHODS: Forty patients with reflux esophagitis were divided into three groups by the status of H. pylori and therapy: group A (n=15), H. pylori (+) and omeprazole 20 mg; group B (n=15), H. pylori (+) and omeprazole 20 mg + vitamin C 1200 mg; and group C (n=10), H. pylori (-) and omeprazole 20 mg. In all three groups, the mucosal interleukin (IL)-8 contents, H. pylori colonization density, neutrophil infiltration in the corpus, and serum gastrin were evaluated at entry and 2 weeks after starting therapy; in group B, serum vitamin C levels were also measured. RESULTS: In group A, the IL-8 contents and the degree of neutrophil infiltration during therapy exceeded those at entry, whereas in groups B and C, these values did not change significantly with treatment. Helicobacter pylori colonization density during therapy was similar to that at entry in all three groups. The serum gastrin (in all groups) and vitamin C levels (in group B) during therapy exceeded those at entry. CONCLUSIONS: Potent acid suppression worsens H. pylori-associated corpus gastritis, although such worsening gastritis may be inhibited by vitamin C.     

Comparison of Helicobacter pylori eradication rates of standard 14-day quadruple treatment and novel modified 10-day, 12-day and 14-day sequential treatments

Background & aimThis study aimed to compare the efficacy and safety of bismuth-included standard regimen and modified sequential treatments in Turkey, where the success rate of standard triple therapy is very low.MethodsOne-hundred and sixty patients with dyspeptic complaints and naïve Helicobacter pylori infection were randomized into four groups: 41 patients received standard 14-day quadruple treatment (STD) (Rabeprazole 20 mg-bid, bismuth subcitrate (120 mg-qid), Tetracycline 500 mg-qid, Metronidazole 500 mg-tid) for 2 weeks. The modified sequential therapy groups received 20 mg rabeprazole and 1 g amoxicillin, twice daily for the first 5 days, followed by Rabeprazole 20 mg-bid, bismuth subcitrate (120 mg-qid), Tetracycline 500 mg-qid, Metronidazole 500 mg-tid for the remaining 5 (10 day sequential therapy group-10S) (42 patients), 7 (12 day sequential therapy group-12S) (42 patients) and 9 (14 day sequential therapy group-14S) (41 patients) days.ResultsThe overall compliance and H. pylori eradication rate among the 160 patients who completed the H. pylori eradication regimens were 86.9% (139/160) and 78.1% (125/160), respectively. The results were not statistically different between groups in the eradication rates. Per-protocol eradication rates were 76.5% in STD, 71.4% in 10S, 82.4% in 12S and 83.3% in 14S groups (p = 0.7). Intention-to-treatment rates were 77.5% in STD, 72.5% in 10S, 82.5% in 12S and 80.0% in 14S groups (p = 0.5).ConclusionThe eradication rates of standard 14-day and different sequential quadruple treatment regimens are comparable and much more higher than with standard 14-day triple H. pylori eradication treatment that has been reported previously in Turkey.
