Effectiveness of 10 day-sequential therapy for Helicobacter pylori eradication in Korea

BACKGROUND/AIMS: Antibiotic resistance and poor compliance are the main causes of Helicobacter pylori (H. pylori) eradication failure. Proton pump inhibitor (PPI)-based triple therapy is the most preferred regimen in clinical practice. However, a critical fall in the H. pylori eradication rate has been observed in the recent years. A novel 10 day-sequential therapy consists of five days of dual therapy followed by five days of triple therapy regimen has recently been described. We aimed to evaluate whether 10 day-sequential therapy eradicated H. pylori infection better than the PPI-based triple therapy in Korea. METHODS: 158 patients with proven H. pylori infection were randomized to receive either 10 day-sequential therapy (20 mg of omeprazole, 1.0 g of amoxicillin, each administered twice daily for the first 5 days, followed by 20 mg of omeprazole, 500 mg of clarithromycin, 500 mg of metronidazole, each administered twice daily for the remaining 5 days) or PPI-based triple therapy (20 mg of omeprazole, 1.0 g of amoxicillin, 500 mg of clarithromycin, each administered twice daily for 1 week). Outcome of eradication therapy was assessed 8 weeks after the cessation of treatment. RESULTS: Eradication rates of 10 day-sequential therapy and PPI-based triple therapy were 77.9% (60/77) and 71.6% (58/81) by intention to treat analysis, respectively (p=0.361). By per protocol analysis, eradication rates of 10 day-sequential therapy and triple therapy were 85.7% (60/70) and 76.6% (58/76), respectively (p=0.150). There were no significant differences in adverse event rates and treatment compliance between two groups. CONCLUSIONS: The 10 day-sequential therapy regimen failed to achieve significantly higher eradication rates than PPI-based triple therapy.     

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.     

幽门螺杆菌感染治疗现状与展望

随着时间的变迁,幽门螺杆菌(Helicobacter pylori,H.pylori)对常用抗生素的耐药率逐渐增加,其根除率逐渐下降。四联疗法已成为当前治疗H.pylori的主要一线方案,另外欧州MaastrichtIV共识意见中还推荐了序贯疗法和伴同疗法。在H.pylori对常用抗生素耐药的情况下,对于如何提高H.pylori根除率,我国H.pylori学者正在进行H.pylori治疗新路径探索:(1)三联(或四联)联合中药治疗;(2)三联(或四联)联合益生菌治疗;(3)探索口腔H.pylori对H.pylori根除治疗的影响;(4)强调个体化治疗。今天的新思路也许会成为明天治疗H.pylori的新手段。

Efficacy of levofloxacin-based triple therapy as second-line Helicobacter pylori eradication]

BACKGROUND/AIMS: Bismuth-based quadruple therapy for second-line eradication treatment achieves the eradication rate ranging from 70% to 81% due to antimicrobial resistance and poor compliance. The aim of this study was to compare the eradication rate of levofloxacin-based triple therapy with that of bismuth-based quadruple therapy in second-line Helicobacter pylori (H. pylori) eradication therapy. METHODS: Seventy-six outpatients with persistent H. pylori infection after first-line triple therapy were enrolled in this prospective randomized trial. The subjects were randomized to receive levofloxacin 300 mg, amoxicillin 1 g, and pantoprazole 20 mg, given twice daily for 7 days (LAP group), or metronidazole 500 mg twice, tetracycline 500 mg four times, and pantoprazole 20 mg twice, bismuth subcitrate 600 mg twice daily for 7 days (MTPB group). Eradication was confirmed with (13)C-urea breath test or rapid urease test 4 weeks after the cessation of therapy. RESULTS: Among Seventy-six patients initially included, eleven were lost during follow-up. The eradication rates, expressed as intention to treat (ITT) and per protocol (PP) analyses, were 51.6% and 53.3% in the LAP group, and 48.9% and 62.9% in the MTPB group, respectively. There was no significant difference in H. pylori eradication rates between the two groups (p=0.815 by ITT, p=0.437 by PP). LAP regimen was better tolerated than MTPB regimen with lower incidence of side effects (10.0% versus 31.4%, p=0.03). CONCLUSIONS: H. pylori eradication rates of levofloxacin-based triple therapy and bismuth-based quadruple therapy were not significantly different in second-line H. pylori eradication therapy, and low incidence of side effects was observed in levofloxacin-based triple therapy.     

The efficacy of levofloxacin based triple therapy for Helicobacter pylori eradication]

BACKGROUND/AIMS: The failure rates of first and second line therapies of Helicobacter pylori (H. pylori) eradication range from 15 to 20%. This study was aimed to evaluate the efficacy and safety of levofloxacin based triple therapy compared with standard triple or quadruple therapy for H. pylori eradication in Korea. METHODS: We enrolled two hundred and sixty seven patients with presence of H. pylori infection. One hundred and forty-one patients were treated with levofloxacin based triple therapy (LAP; levofloxacin, amoxicillin, proton pump inhibitor; PPI), and 126 patients were treated with standard triple therapy (CAP; clarithromycin, amoxicillin, PPI). We retreated the patients who had failed in H. pylori eradication with standard quadruple second-line therapy (MTPB; metronidazole, tetracycline, PPI, bismuth subcitrate) or levofloxacin based therapy (LAP or LCP; levofloxacin, clarithromycin, PPI). RESULTS: In first line therapy of H. pylori eradication, the eradication rates of levofloxacin based triple therapy and standard triple therapy were 69.8% and 74.0% respectively (p=0.52). In second-line therapy, the eradication rate of levofloxacin based triple therapy and standard quadruple therapy were 62.5% and 40.0% respectively (p=0.34). CONCLUSIONS: Levofloxacin based triple therapy is effective as standard regimen to eradicate H. pylori infection and is useful for an alternative rescue therapy as well.     

Comparison of the effectiveness of quadruple salvage regimen for Helicobacter pylori infection according to the duration of treatment]

BACKGROUND/AIMS: At present, triple therapy schemes are recommended by national and international consensus conferences for the treatment of Helicobacter pylori (H. pylori) infection. However, even with the most effective current treatment regimens, about 10-20% of patients fail to eradicate H. pylori, necessitating alternative strategy to eradicate H. pylori in primary treatment failure. Therefore, we performed this study to evaluate the efficacy of quadruple therapy and to compare 1 and 2-week quadruple regimen as a second-line therapy. METHODS: The hospital records of 155 patients who failed to the standard triple therapy (proton pump inhibitor, amoxicillin, clarithromycin) were reviewed retrospectively, and divided the 1 or 2 weeks OBMT regimen (omeprazole 20 mg bid, bismuth salt 120 mg qid, metronidazole 500 mg tid, tetracycline 500 mg qid). Presence of H. pylori infection and side-effects of the treatment regimen were assessed 4 weeks after the cessation of treatment. RESULTS: One hundred and eight male and 47 female (mean age, 52.2+/-15.4) patients were enrolled. The overall eradication rate of H. pylori with quadruple therapy was 83.9% and the eradication rate was similar between 1 and 2 weeks of OBMT regimen (76.8% in OBMT 1 week, 87.9% in OBMT 2 weeks, respectively p=0.110). CONCLUSIONS: Quadruple therapy is an effective salvage regimen for H. pylori eradication after the failure of standard triple therapy. One week quadruple therapy is not significantly different from 2-weeks regimen as the second-line option for H. pylori eradication.

One-week quadruple therapy is an effective salvage regimen for Helicobacter pylori infection in patients after failure of standard triple therapy

Standard triple therapy remains an important option for eradicating Helicobacter pylori (Hp) in developing countries because of its relatively low cost. However, salvage therapies after failure of this regimen remain undefined. The authors therefore investigate the efficacy of 1-week quadruple therapy as a second-line treatment of Hp infection after failure of standard triple therapy. Seventy-eight patients who failed Hp eradication using a 2-week bismuth-based triple therapy were enrolled and received a course of 1-week quadruple therapy (lansoprazole, 30 mg twice daily; bismuth subcitrate, 120 mg four times daily; clarithromycin, 500 mg twice daily; and amoxicillin, 1,000 mg twice daily) as a salvage regimen. The Hp status was reassessed 7 weeks after cessation of therapy. Among the 78 patients, Hp eradication was achieved in 65 (83%, 95% confidence interval = 75-91%) by intention-to-treat analysis. Only five (6%) patients had side effects, and all (100%) showed good drug compliance. Multivariate analysis disclosed that coffee drinking was an independent factor for treatment failure (odds ratio = 5.3, 95% confidence interval = 1.2-23.6, p = 0.028). The authors therefore conclude that their 1-week quadruple therapy is an effective salvage regimen for Hp infection after failure of standard triple therapy in the population examined. The benefits of this regimen include the high eradication rate, the short duration of treatment, fewer side effects, and good drug compliance. Coffee consumption possibly is an important factor in failure of the rescue regimen. The mechanisms underlying the association between coffee drinking and eradication failure require further research.     

A 3-day anti-Helicobacter pylori therapy is a good alternative for bleeding peptic ulcer patients with Helicobacter pylori infection

BACKGROUND/AIMS: One-week triple therapy has been recommended as a standard regimen for eradicating Helicobacter pylori infection. The emergence of antibiotic-resistant strains, adverse drug effects, poor compliance and high cost of therapy add problems to the management of these patients. In this study, we assessed whether a 3-day triple therapy could be effective in eradicating Helicobacter pylori infection in bleeding peptic ulcer patients. METHODOLOGY: Peptic ulcer patients with Helicobacter pylori infection were enrolled in this study. Patients enrolled at the outpatient department (group A) received a 7-day oral regimen: bismuth subcitrate colloid 300 mg + amoxicillin 500 mg + metronidazole 250 mg four times per day. Patients who were admitted to the wards due to peptic ulcer bleeding (group B) received a 3-day regimen including omeprazole 40 mg intravenously every 6 hours, amoxicillin 500 mg + metronidazole 250 mg orally four times daily after hemostasis had been achieved. Patients of both groups received omeprazole 20 mg once per day or cimetidine 400 mg twice daily per os for at least-one month after anti-Helicobacter pylori therapy. We followed every patient endoscopically two months after anti-Helicobacter pylori therapy. RESULTS: From June 1997 to April 1999, a total of 57 patients (30 in group A and 27 in group B) with gastric or duodenal ulcer and Helicobacter pylori infection completed anti-Helicobacter pylori therapy. Two months after anti-Helicobacter pylori therapy, peptic ulcer was found to be healed with a scar in 26 (86.7%) of group A and 23 (85.2%) of group B (P > 0.1). The eradication rates of Helicobacter pylori in the two groups were not significantly different in an intention-to-treat analysis [group A: 78.8% (26/33), 95% CI: 64.9-92.7%; group B: 80% (24/30), 95% CI: 65.7-94.3%, P > 0.1] and in a per protocol analysis [group A: 86.7% (26/30), 95% CI: 74.5-98.9%, group B: 88.9% (24/27), 95% CI: 77.1-100.7%, P > 0.1]. Fewer side effects occurred in group B (3/30) than those in group A (7/33) (P > 0.1). CONCLUSIONS: In patients with peptic ulcer bleeding a 3-day anti-Helicobacter pylori therapy is a good alternative for eradicating Helicobacter pylori infection.
