Abstract
Helicobacter pylori infection is one of the most common infectious diseases worldwide. H. pylori is responsible for substantial gastrointestinal morbidity with a high disease burden. Since the revision of the H. pylori Clinical Practice Guidelines in 2013 in Korea, the eradication rate of H. pylori has gradually decreased with the use of a clarithromycin based triple therapy. According to a nationwide randomized controlled study by the Korean College of Helicobacter and Upper Gastrointestinal Research released in 2018, the intention-to-treat eradication rate was only 63.9%, which was mostly due to increased antimicrobial resistance to clarithromycin. The clinical practice guidelines for treatment of H. pylori were updated based on evidence-based medicine from a meta-analysis conducted on a target group receiving the latest level of eradication therapy. The draft recommendations developed based on the meta-analysis were finalized after expert consensus on three recommendations regarding the indication for treatment and eight recommendations on the treatment itself. These guidelines were designed to provide clinical evidence for the treatment of H. pylori to patients, nurses, medical school students, policymakers, and clinicians. These may differ from current medical insurance standards, and will be revised if more evidence emerges in the future.

Abstract
Helicobacter pylori infection is one of the most common infectious diseases worldwide. Although the prevalence of H. pylori is gradually decreasing, approximately half of the world's population still becomes infected with this disease. H. pylori is responsible for substantial gastrointestinal morbidity worldwide, with a high disease burden. It is the most common cause of gastric and duodenal ulcers and gastric cancer. Since the revision of the H. pylori clinical practice guidelines in 2013 in Korea, the eradication rate of H. pylori has gradually decreased with the use of a clarithromycin-based triple therapy for 7 days. According to a nationwide randomized controlled study conducted by the Korean College of Helicobacter and Upper Gastrointestinal Research released in 2018, the intention-to-treat eradication rate was only 63.9%, which was mostly due to increased antimicrobial resistance, especially from clarithromycin. The clinical practice guidelines for the treatment of H. pylori were updated according to evidence-based medicine from a meta-analysis conducted on a target group receiving the latest level of eradication therapy. The draft recommendations developed based on the meta-analysis were finalized after an expert consensus on three recommendations regarding the indication for treatment and eight recommendations for the treatment itself. These guidelines were designed to provide clinical evidence for the treatment (including primary care treatment) of H. pylori infection to patients, nurses, medical school students, policymakers, and clinicians. These may differ from current medical insurance standards and will be revised if more evidence emerges in the future.

Abstract
Background/Aims: As antibiotic resistance increases and new first-line therapies emerge, salvage therapies for <i>Helicobacter pylori</i> (<i>H. pylori</i>) eradication failures are becoming more common and complicated. This study aimed to systematically review overall salvage regimens after previous failure of <i>H. pylori</i> eradication.Materials and Methods: A systematic review of randomized clinical trials evaluating salvage therapies after previous <i>H. pylori</i> eradication failure was performed. A meta-analysis was conducted when an adequate number of studies suitable for grouping was found.Results: Overall, 36 studies with 77 treatment arms were identified, and they were highly heterogeneous regarding previously failed regimens and salvage regimens under comparison. Bismuth quadruple therapy after failure of standard triple therapy showed a pooled intention-to-treat (ITT) eradication rate of 75.5% (95% CI, 71.6~79.1%), and the rates were significantly higher with 14-day therapy than 7-day therapy by 9% (95% CI, 2~15%). Levofloxacin triple therapy after failure of standard triple therapy demonstrated a pooled ITT eradication rate of 73.3% (95% CI, 68.4~77.3%). In direct comparison, the two regimens were not significantly different in eradication rates. No study evaluated salvage regimens after the failure of bismuth or non-bismuth quadruple therapy.Conclusions: The current studies regarding salvage regimens are highly heterogeneous. Bismuth quadruple therapy and levofloxacin triple therapy may be a reliable option after failure of standard triple therapy, but the regional profile of antibiotic resistance should be considered. Further studies are needed for salvage regimens after failure of non-bismuth or bismuth quadruple therapy.

Abstract
Helicobacter pylori (H. pylori) infection is one of the most common infectious diseases worldwide. Although its incidence is gradually decreasing, about half of the world's population still get infected. H. pylori infection is responsible for substantial gastrointestinal morbidity worldwide. It is the most common cause of gastric and duodenal ulcers as well as gastric cancer. Since the revision of the H. pylori Clinical Practice Guidelines in 2013, the eradication rate of H. pylori has gradually decreased with the use of classical triple therapy, wherein amoxicillin, clarithromycin, and proton pump inhibitors are administered, for 7 days. According to a nationwide randomized controlled study conducted by the Korean College of Helicobacter and Upper Gastrointestinal Research released in 2018, the intention-to-treat eradication rate was only 63.9%, which was due to increased antimicrobial resistance induced by the use of antibiotics, especially clarithromycin. The update of clinical practice guideline for treatment of H. pylori was developed based on evidence-based medicine by conducting a meta-analysis. The draft recommendations were finalized after expert consensus on three recommendations regarding the indication for treatment and eight recommendations on the treatment itself. These guidelines are designed to provide patients, nurses, medical school students, policymakers, and clinicians with clinical evidence to guide primary care and treatment of H. pylori infection. These may differ from current medical insurance standards and will be revised further, if necessary, based on research-based evidence.

Abstract
Third generation of quinolones, such as levofloxacin and moxifloxacin, -containing regimens are often used in second-line or rescue treatment of Helicobacter pylori infection. However, the increasing antibiotic resistance to quinolones affects the efficacies of quinolones-containing therapies in recent years. Therefore, there is a need to enhance the effectiveness of quinolones-containing therapies. Sitafloxacin, a fourth-generation quinolone, and vonoprazan, a novel potassium-competitive acid blocker, are now available as more effective treatment options. The aim of this paper is to summarize the current evidence of quinolone-containing therapies in rescue treatments, and to discuss the importance of drug sensitivity tests or analysis of gyrA mutation before treatments.

Abstract
Background/Aims Hybrid therapy was successful in eradicating Helicobacter pylori (H. pylori) according to previous reports. However, to the best of our knowledge, there have only been a few studies evaluating the optimal choice after hybrid failure. Hence, we aimed to evaluate the efficacy of moxifloxacin-containing triple therapy after hybrid therapy failure in H. pylori eradication. Methods Between January 2013 and March 2016, we retrospectively reviewed patients who underwent failed hybrid therapy, as first line treatment, in eradicating H. pylori (rabeprazole and amoxicillin b.i.d for 14 days, in addition to clarithromycin and metronidazole b.i.d for final 7 days). Then, we investigated the eradication rates of moxifloxacin-containing triple therapy (rabeprazole, amoxicillin b.i.d and moxifloxacin qd) as the second line of treatment. Intention-to-treat (ITT) and per-protocol (PP) analyses were used to determine the eradication rate. We evaluated the status of H. pylori by using 13C-urea breath test 6 weeks after the final treatment. Moreover, compliance and adverse effects of each patient were analyzed. Results Among those who failed the initial hybrid therapy, 11 patients received moxifloxacin-containing triple therapy. The overall eradication rates, as determined by ITT and PP, were 72.7% (n=8/11) and 80% (n=8/10), respectively. The compliance rate was 100%, and there were no serious adverse effects. Conclusions Moxifloxacin-containing triple therapy can be used as a second line therapy in case of hybrid therapy failure. A large scale study is necessary to confirm the findings of this study and establish clinical evidence.

Abstract
BACKGROUND/AIMS Bismuth-containing quadruple and moxifloxacin-based triple regimens are recommended as second-line therapy for Helicobacter pylori infection. The aim of this study was to compare the efficacy of each regimen. METHODS From August 2004 to October 2012, a total of 949 patients (mean age, 54.32±12.08 years; male, 49.4%) who failed H. pylori eradication with a standard triple regimen were included. Patients treated with a bismuth-containing quadruple regimen for 7 and 14 days were designated as 7-BMT and 14-BMT, respectively, and those treated with a moxifloxacin-based triple regimen for 7 and 14 days were designated as 7-MA and 14-MA, respectively. H. pylori eradication was confirmed using the (13)C-urea breath test, rapid urease test or histology. RESULTS The eradication rates by 7-BMT, 14-BMT, 7-MA, and 14-MA were 66.4% (290/437), 71.1% (113/159), 53.1% (51/96), and 73.5% (189/257), respectively, by intention-to-treat analysis (ITT) and 76.5% (284/371), 83.8% (109/130), 55.6% (50/90), and 80.6% (187/232), respectively, by per-protocol analysis (PP). The eradication rates were higher in 14-BMT than 7-BMT by the ITT and PP analyses (p=0.277 and p=0.082, respectively). The 14-BMT and 14-MA treatments showed similar efficacies by ITT and PP (p=0.583 and p=0.443, respectively). CONCLUSIONS The 7-BMT, 14-BMT, and 14-MA treatments showed similar and suboptimal efficacies. In both regimens, extending the duration of treatment may be reasonable considering the high level of antibiotic resistance in Korea.

Abstract
Background/Aims Retreatment after initial treatment failure for Helicobacter pylori is very challenging. The purpose of this study was to evaluate the efficacies of moxifloxacin-containing triple and bismuth-containing quadruple therapy. Methods A total of 151 patients, who failed initial H. pylori treatment, were included in this retrospective cohort study. The initial regimens were standard triple, sequential, or concomitant therapy, and the efficacies of the two following second-line treatments were evaluated: 7-day moxifloxacin-containing triple therapy (rabeprazole 20 mg twice a day, amoxicillin 1,000 mg twice a day, and moxifloxacin 400 mg once daily) and 7-day bismuth-containing quadruple therapy (rabeprazole 20 mg twice a day, tetracycline 500 mg 4 times a day, metronidazole 500 mg 3 times a day, and tripotassium dicitrate bismuthate 300 mg 4 times a day). Results The overall eradication rates after moxifloxacin-containing triple therapy and bismuth-containing quadruple therapy were 69/110 (62.7%) and 32/41 (78%), respectively. Comparison of the two regimens was performed in the patients who failed standard triple therapy, and the results revealed eradication rates of 14/28 (50%) and 32/41 (78%), respectively (p=0.015). The frequency of noncompliance was not different between the two groups, and there were fewer adverse effects in the moxifloxacin-containing triple therapy group (2.8% vs 7.3%, p=0.204 and 25.7% vs 43.9%, p=0.031, respectively). Conclusions Moxifloxacin-containing triple therapy, a recommended second-line treatment for initial concomitant or sequential therapy failure, had insufficient efficacy.

Abstract
PURPOSE To determine the inclusion of women and the sex-stratification of results in moxifloxacin Clinical Trials (CTs), and to establish whether these CTs considered issues that specifically affect women, such as pregnancy and use of hormonal therapies. Previous publications about women's inclusion in CTs have not specifically studied therapeutic drugs. Although this type of drug is taken by men and women at a similar rate, adverse effects occur more frequently in the latter. METHODS We reviewed 158 published moxifloxacin trials on humans, retrieved from MedLine and the Cochrane Library (1998-2010), to determine whether they complied with the gender recommendations published by U.S. Food and Drug Administration Guideline. RESULTS Of a total of 80,417 subjects included in the moxifloxacin CTs, only 33.7% were women in phase I, in contrast to phase II, where women accounted for 45%, phase III, where they represented 38.3% and phase IV, where 51.3% were women. About 40.9% (n=52) of trials were stratified by sex and 15.3% (n=13) and 9% (n=7) provided data by sex on efficacy and adverse effects, respectively. We found little information about the influence of issues that specifically affect women. Only 3 of the 59 journals that published the moxifloxacin CTs stated that authors should stratify their results by sex. CONCLUSIONS Women are under-represented in the published moxifloxacin trials, and this trend is more marked in phase I, as they comprise a higher proportion in the other phases. Data by sex on efficacy and adverse effects are scarce in moxifloxacin trials. These facts, together with the lack of data on women-specific issues, suggest that the therapeutic drug moxifloxacin is only a partially evidence-based medicine.

The efficacy of moxifloxacin-based triple therapy in treatment of Helicobacter pylori infection: a systematic review and meta-analysis of randomized clinical trials. Braz J Med Biol Res 2013; 46:607-13. [PMID: 23903685 PMCID: PMC3859334 DOI: 10.1590/1414-431x20132817] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2012] [Accepted: 04/25/2013] [Indexed: 12/18/2022] Open
Abstract
Recent evidence shows that moxifloxacin could exert an antimicrobial effect
against Helicobacter pylori in both in vitro
and in vivo models. To systematically evaluate whether
moxifloxacin-containing triple therapy could improve eradication rates and
reduce side effects in first-line or second-line anti-H. pylori
treatment, eligible articles were identified by searches of electronic
databases. We included all randomized trials comparing moxifloxacin-based triple
therapy with standard triple or quadruple therapy during H.
pylori eradication treatment. Statistical analysis was performed
with Review Manager 5.0.10. Subanalysis/sensitivity analysis was also performed.
We identified seven randomized trials (n=1263). Pooled H.
pylori eradication rates were 79.03% (95%CI: 75.73-82.07) and
68.33% (95%CI: 64.44-72.04) for patients with moxifloxacin-based triple therapy
or with standard triple or quadruple therapy, respectively (intention-to-treat
analysis). The odds ratio (OR) was 1.82 (95%CI: 1.17-2.81), the occurrence of
total side effects was 15.23% (95%CI: 12.58-18.20) and 27.17% (95%CI:
23.64-30.92) for groups with or without moxifloxacin, and the summary OR was
0.45 (95%CI: 0.26-0.77). In subgroup analyses, we noted that the second-line
eradication rate in the moxifloxacin group was significantly higher than that in
the quadruple therapy group (73.33 vs 60.17%, OR: 1.78, 95%CI:
1.16-2.73, P<0.001). However, there was no difference in first-line
eradication treatment. Findings from this meta-analysis suggest that
moxifloxacin-based triple therapy is more effective and better tolerated than
standard triple or quadruple therapy. Therefore, a moxifloxacin-based triple
regimen should be used in the second-line treatment of H.
pylori infection.

Abstract
BACKGROUND Triple therapy with a proton pump inhibitor, moxifloxacin, and amoxicillin has been proven effective in first-line treatment of Helicobacter pylori infection. AIM To explore 1, the value of triple therapy with esomeprazole, moxifloxacin, and amoxicillin in second-line or rescue treatment of Caucasian patients and 2, the impact of treatment duration on eradication success. METHODS H. pylori-infected patients with at least one previous treatment failure were randomized to oral esomeprazole 20 mg b.i.d., moxifloxacin 400 mg o.d., and amoxicillin 1000 mg b.i.d. for either 7 (EMA-7) or 14 days (EMA-14). Eradication was confirmed by 13C urea breath test. Antimicrobial susceptibility testing was performed in all patients at baseline and in patients who failed treatment. RESULTS Eighty patients were randomized, and 60% had ≥ 2 previous treatment failures. Pretreatment resistance against clarithromycin and metronidazole was found in 70.5 and 61.5% of cases, respectively. The intention-to-treat eradication rate was significantly higher after EMA-14 compared with EMA-7 (95.0 vs 78.9%, p = .036). No independent risk factor for treatment failure could be identified. There were no serious adverse events. Five of the EMA-14 patients (12.5%) compared with none of the EMA-7 patients discontinued prematurely because of adverse events (p = .031). Post-treatment resistance against moxifloxacin was found in one of seven patients with isolated organisms (14.3%). CONCLUSION Second-line/rescue H. pylori eradication therapy with esomeprazole, moxifloxacin, and amoxicillin is very effective and well tolerated. Fourteen days of treatment significantly increase the eradication rate but also the rate of adverse events.

Abstract
BACKGROUND Moxifloxacin-containing triple therapy has been suggested as an alternative second-line therapy for Helicobacter pylori infection. AIMS To systematically review the efficacy and tolerance of moxifloxacin-containing triple therapy in second-line H. pylori eradication, and to conduct a meta-analysis of studies comparing this regimen with bismuth-containing quadruple therapy. MATERIALS AND METHODS Electronic databases including Medline, Embase, Cochrane controlled trials register, Web of Science, PubMed, Chinese Biomedical Literature Database (updated to December 2010), and manual searches were conducted. A meta-analysis of all randomized controlled trials (RCTs) comparing moxifloxacin-containing triple therapy to bismuth-containing quadruple therapy in the second-line treatment of H. pylori infection was performed. RESULTS Seven RCTs including 787 patients were assessed. The meta-analysis showed that the eradication rate in the moxifloxacin group was significantly higher than that in the quadruple therapy group (74.9 vs 61.4%, OR 1.89, 95% CI: 1.38-2.58, p < .0001); besides, the rates of side effects and discontinuing therapy because of side effects in the moxifloxacin group were significantly lower than those in the quadruple therapy group (side effects: 10.1 vs 27.8%, OR 0.27, 95% CI: 0.18-0.41, p < .00001; discontinuing therapy because of side effects: 1.4 vs 8.2%, OR 0.18, 95% CI: 0.08-0.40, p < .0001). These results were constant in the sensitivity analyses. CONCLUSION Moxifloxacin-containing triple regimen is more effective and better tolerated than the bismuth-containing quadruple therapy in the second-line treatment of H. pylori infection.

Abstract
New generations of fluoroquinolones, like levofloxacin and moxifloxacin, exhibit a broad-spectrum activity against Gram-positive and Gram-negative bacteria, and have been successfully introduced into the treatment of Helicobacter pylori infection. Based on a large body of evidence, current guidelines recommend the use of levofloxacin- or moxifloxacin-containing proton-pump inhibitor (PPI) triple therapies in second-line or rescue treatment of H. pylori infection. The efficacy of standard PPI triple therapies has substantially declined during the last decade, mainly due to increasing resistance against the key antibiotics clarithromycin and metronidazole. Therefore, alternative strategies for first-line therapy of H. pylori infection have been evaluated in a considerable number of clinical trials including sequential regimens, nonbismuth quadruple regimens, and quinolone-containing PPI triple therapy regimens. The aim of this paper is to summarize the current body of evidence of levofloxacin- and moxifloxacin-containing regimens in first-line treatment of H. pylori infection, and to discuss the risks and benefits of these strategies in the light of increasing resistance of H. pylori to quinolones.

Abstract
OBJECTIVE The main aim of this meta-analysis was to compare the efficacy and safety of clarithromycin and second-generation fluoroquinolone-based triple therapy vs. bismuth-based quadruple therapy for the treatment of persistent Helicobacter pylori infection. METHODS A systematic literature search was conducted for articles and abstracts from 1981 to March 2009 using Medline, PubMed, EMBase, Google Scholar and CNKI (Chinese), Wanfang (Chinese) digital database and recent Digestive Disease Week, United European Gastroenterology Week, and European Helicobacter Study Group conferences were also performed. Boolean operators (NOT, AND, OR) were used in succession to narrow and widen the search. Sixteen articles and four abstracts met the inclusion criteria, and were included in the meta-analysis by using Review Manager 4.2.8. RESULTS The eradication rates demonstrated that clarithromycin-based triple therapy is inferior to bismuth-based quadruple therapy (OR = 0.53, 95% CI: 0.35-0.80, P = 0.002). Thirteen RCTs compared levofloxacin-based triple therapy vs. bismuth-based quadruple therapy, the eradication rates of the two regimens were shown to have no significant difference (OR = 1.43, 95% CI: 0.82-2.51, P = 0.21). But the eradication rates demonstrated superiority of the 10-day levofloxacin-based triple therapy over 7-day bismuth-based quadruple therapy (OR = 4.79, 95% CI: 2.95-7.79, P < 0.00001). Levofloxacin-based triple therapy was better tolerated than bismuth-based quadruple therapy with lower rates of side effects (OR = 0.41, 95% CI: 0.27-0.61, P < 0.0001), and lower rates of discontinuation of therapy due to adverse events (OR = 0.13, 95% CI: 0.06-0.33, P < 0.0001). Furthermore, our meta-analysis suggested that the eradication rates of the moxifloxacin-based triple therapy has a slight superiority to bismuth-based quadruple therapy, but there was no significant difference between them. CONCLUSION Second-generation fluoroquinolone-based triple therapy can be suggested as the regimen of choice for rescue therapy in the eradication of persistent H. pylori infection especially 10-day levofloxacin-based triple therapy.

Abstract
UNLABELLED Moxifloxacin has been used in the first-line treatment of Helicobacter pylori infection. The optimal dosage and duration have not been assessed. AIM To evaluate the effectiveness of moxifloxacin, amoxicillin and esomeprazole in four regimens, in previously untreated patients infected by H. pylori. METHODS AND PATIENTS Patients were randomly assigned to: esomeprazole 20 mg b.i.d., amoxicillin 1g b.i.d., and one of each of the four following dosages of moxifloxacin: moxifloxacin 400 mg b.i.d. for 10 days (EAM800x10), moxifloxacin 400 mg b.i.d. for 7 days (EAM800x7), moxifloxacin 400 mg b.i.d. for 5 days (EAM800x5), moxifloxacin 400 mg o.i.d. for 10 days (EAM400x10). Eradication was assessed by the Urea Breath Test (UBT) 2 months following the end of therapy. RESULTS Ninety-four, 102, 92 and 105 patients were recruited in EAM800x10, EAM800x7, EAM800x5, and EAM400x10 respectively. The eradication rate was for Intention-To-Treat (ITT) and Per Protocol (PP) analyses: EAM800x10 group ITT: 90.4%, PP: 94.4%; EAM800x7 group ITT: 80.3%, PP: 86.3%; EAM800x5 group ITT: 71.4%, PP: 75.2%; EAM400x10 group ITT: 80.0%, PP 84.8%. A statistically significant difference was reached between EAM800x10 vs. EAM800x7 (ITT and PP: P<0.05), and between EAM800x10 vs. EAM800x5 (ITT and PP: P<0.01) and vs. EAM400x10 (ITT: P<0.05; PP: P<0.04). Thirty patients treated unsuccessfully with EAM800x5 and EAM400x10 were re-treated with EAM800x10 with an eradication rate of 86.7% (ITT) and 92.2% (PP). Nineteen patients with positive UBT after EAM800x10 and EAM800x7 underwent a second-line rifabutin-based therapy with an eradication rate of 84.2% (ITT and PP). CONCLUSION A triple therapy with 800 mg of moxifloxacin a day for 10 days is more effective than the same treatment for 5 or 7 days and a treatment with 400mg of moxifloxacin a day for 10 days for the first-line eradication of H. pylori infection. The high cost of moxifloxacin-based treatment however, may limit its wide use as first-line treatment of H. pylori infection.

Abstract
Peptic ulcer disease had a tremendous effect on morbidity and mortality until the last decades of the 20th century, when epidemiological trends started to point to an impressive fall in its incidence. Two important developments are associated with the decrease in rates of peptic ulcer disease: the discovery of effective and potent acid suppressants, and of Helicobacter pylori. With the discovery of H pylori infection, the causes, pathogenesis, and treatment of peptic ulcer disease have been rewritten. We focus on this revolution of understanding and management of peptic ulcer disease over the past 25 years. Despite substantial advances, this disease remains an important clinical problem, largely because of the increasingly widespread use of non-steroidal anti-inflammatory drugs (NSAIDs) and low-dose aspirin. We discuss the role of these agents in the causes of ulcer disease and therapeutic and preventive strategies for drug-induced ulcers. The rare but increasingly problematic H pylori-negative NSAID-negative ulcer is also examined.

Abstract
BACKGROUND AND AIM The aim of this study was to evaluate the efficacy of a moxifloxacin-containing triple therapy as second-line treatment for Helicobacter pylori infection. We also investigated the effect of treatment duration and antibiotic resistance on the eradication rate of this therapy. METHODS We prospectively enrolled patients found to have persistent H. pylori infections after failure of first-line proton-pump inhibitor-based triple therapy. Patients took moxifloxacin (400 mg q.d.), amoxicillin (1000 mg b.i.d.), and esomeprazole (20 mg b.i.d.). The eradication rate, drug compliance, and adverse event rates were evaluated. Minimal inhibitory tests were performed for moxifloxacin and amoxicillin by the agar dilution method. RESULTS In 2004, 41 patients were treated for 7 days. The intention-to-treat and per-protocol eradication rates (ITT/PP) were 75.6/83.8%. Moxifloxacin resistance was 5.6%. Therapy was extended to 10 days during 2005-2006 and 139 patients were treated. The ITT/PP eradication rates were 71.9/82.6%; moxifloxacin resistance had increased to 12%. The final group of 181 patients in 2007-2008 who were treated for 14 days also had low eradication rates (68/79.9%), but there was no statistical significance in the efficacy among the treatment periods. Moxifloxacin resistance in 2007-2008 was 28.2%. Side-effect increased with treatment duration (i.e., 9.8, 12.2, and 25.4% at 7, 10, and 14 days, respectively, p = .001). CONCLUSION The 7-day moxifloxacin-containing triple therapy produced an unacceptably low eradication rate. Increasing the duration of therapy was expected to increase the eradication rate, but the expected increased did not materialize, most likely because of coincident marked increase in the prevalence of resistance to moxifloxacin. Tailored treatment based on antibiotic susceptibility testing might be more effective in the achievement of high eradication rate when rapid antibiotic resistance such as moxifloxacin is occurring.
