Background: The increasing of antibiotic resistance in H. pylori has become a main cause for treatment failure. A 10-day levofloxacin containing sequential therapy is efficient and safe in eradication H. pylori infection in an area with high prevalence of clarithromycin resistance. Aims: To evaluate the efficacy of 10day levofloxacin containing sequential therapy as first-line treatment for H. pylori eradication, side effects, symptoms and endoscopic responses and improvement of histological features in Centre Vietnam. Patients and methods: 120 Naïve H. pylori positive patients were received levofloxacin containing sequential therapy (rabeprazole 20mg twice daily, amoxicillin 1g twice daily for 5 days followed by rabeprazole 20mg, levofloxacin 500mg, and tinidazole 500mg, twice daily for 5 more days). These patients tested positive for H. pylori by urease test and gastric mucosal biopsy presented mononuclear cell infiltrating in lamina propria. Results: Intention to treat (ITT) eradication rates of RA-RLT was 73.5%. Per protocol (PP) eradication rates were 81.5%. Overall, 33.7% experienced mild to moderate adverse events. No patient stopped the treatment because of side effects. 6 months after H. pylori eradication clinical symptoms and only edema undergoing endoscopy significantly improved. Grade of activity inflammation and stage of gastritis significantly decreased at 6 months. Intestinal metaplasia and dysplasia did not change significantly at 6 months. Conclusion: 10day levofloxacin containing sequential therapy may be considered as one of the first choices in H. pylori eradication in Central Vietnam. H. pylori eradication may improve clinical symptoms, inflammative activity and stage of gastritis in histology. Key words: H. pylori, gastritis, levofloxacin

The aim of our study was to evaluate the efficacy and tolerability of a ciprofloxacin-based regimen forH. pylorieradication failures as an alternative to bismuth based quadruple therapy.Methods.Design:prospective single-center study. Patients in whom a first eradication trial with omeprazole/esomeprazole, clarithromycin plus amoxicillin or tinidazole/metronidazole had failed were included.H. pylori status:established by histology, rapide urease test and polymerase chain reaction.Intervention:esomeprazole 20 mg, ciprofloxacin 500 mg, and metronidazole 500 mg, administered together before breakfast and dinner for 10 days. Susceptibility testing was performed by the Epsilometer test. Ciprofloxacin resistance was defined as a MIC of ≥1 μg/mL. Eradication was established by a negative 13C-UBT and 4–6 weeks post-therapy. Efficacy and side effects were determined.Results. 34 patients were enrolled, 32 completed the study. Compliance was excellent (100%). Side effects were mild. Ciprofloxacin-based therapy cured 65% (22/34) of patients by intention to treat and 69% (22/32) per protocol analysis. The prevalence of ciprofloxacin resistance was 8%.Conclusions. The effectiveness of ciprofloxacin-based therapy was greatly reduced despite the high prevalence of ciprofloxacin sensitiveH. pyloristrains. Bismuth based quadruple therapy still remain the best choice as a “rescue” regimen in our region.

Aim. To compare 10-day standard triple therapy versus sequential therapy as first-line treatment in patients infected withH. pylori.Methods. One hundredH. pyloripositive patients (diagnosed by rapid urease test and histology), with average age of 47.2, M/F = 28/72, were randomized to receive either standard triple treatment (TT) as follows: lansoprazole 30 mg, clarithromycin 500 mg, and amoxicillin 1 g, b.i.d. for ten days, or sequential treatment (ST) as follows: lansoprazole 30 mg, amoxicillin and placebo 1.0 g b.i.d for the first five days, followed by lansoprazole 30 mg, clarithromycin 500 mg, and tinidazole 500 mg b.i.d, for the remaining five days. Eradication rates were determined 60 days after treatment by urease, histology, or13C-urea breath test.Results. In intention to treat (ITT) analysis, the rate ofH. pylorieradication in the TT and ST groups was the same for both regimens as follows: 86% (43/50), 95% CI 93,3 to 73.4%. In Per protocol (PP) analysis, the rate ofH. pylorieradication in the TT and ST groups was 87.8% (43/49), 95% CI 94,5 to 75.3% and 89.6% (43/48), 95% CI 95,8 to 77.3%, respectively.Conclusions. In Brazil, standard triple therapy is as equally effective as sequential therapy in eradicatingHelicobacter pyloripatients. This study was registered under Clinical Trials with numberISRCTN62400496.

Abstract Background Increasing clarithromycin resistance has led to the need for an alternative first-line therapy for the eradication of Helicobacter pylori (H. pylori) in Korea, and bismuth containing quadruple therapy (BQT) and tailored therapy (TT) have been proposed as alternative regimens. The aim of this study was to compare the eradication rates of BQT and TT as first-line H. pylori eradication therapies. Methods H. pylori infection was diagnosed using the rapid urease test or dual-priming oligonucleotide-based multiplex polymerase chain reaction (DPO-PCR) during endoscopy. Patients positive for H. pylori were divided into two groups; those tested using the rapid urease test received empirical BQT (the BQT group) whereas those tested by DPO-PCR received TT (the TT group). Eradication rates, adverse events, and overall medical costs, which included diagnostic test and eradication regimen costs, were compared. Results Three hundred and sixty patients were included in the study (TT group 178, BQT group 182). The modified intention-to-treat eradication rates of BQT and TT were 88.2% (142/161) and 80.3% (118/147), respectively (p=0.055), and corresponding eradication rates in the per-protocol population were 88.8% (142/160) and 81.4% (118/145) (p=0.07). Compliance and adverse event rates were similar in the two groups. Average medical costs were $ 90.3 per patient in the TT group and $ 75.5 in the BQT group (p=0.000). Conclusions Empirical BQT and tailored therapy were similar in terms of H. pylori eradication rate, safety, and tolerability, but BQT was more cost-effective.

Objective. The eradication rate ofHelicobacter pylori(H. pylori) following standard triple therapy has declined over the past few decades. This study has determined whether high dose dual therapy (PPI and amoxicillin) is adequate for eradicatingH. pyloriin Korea.Methods. This was an open-labeled study ofH. pyloriinfected treatment-naive patients. Subjects received dual therapy for 14 days: ilaprazole 40 mg tablets given twice a day and amoxicillin 750 mg tablets given 4 times a day. At the end of the therapy, the subjects visited the clinic to confirm compliance and monitor for any side effects. Subjects visited again after 4–6 weeks to confirmH. pyloristatus through a urea breath test.Results.The cure rate ofH. pyloriwas 79.3% (23 of 29) (95% confidence interval: 61.6–90.2) in the intention-to-treat analysis and 82.1% (23 of 28) in the per-protocol analysis. Compliance rates were high (96.6%) and side effects were minimal and tolerable.Conclusion.A high dose of ilaprazole + amoxicillin was ineffective as the first-line therapy for eradicatingH. pyloriin Korea. Future studies should focus on intragastric pH measurements and assess amoxicillin resistance.

Background & Aim: Standard 10-day sequential therapy is advised as first-line therapy for Helicobacter pylori (H. pylori) eradication by current Italian guidelines. Some data suggested that a 14-day regimen may achieve higher eradication rates. This study compared the efficacy of sequential therapy administered for either 10- or 14-days.Methods: This prospective, multicenter, open-label study enrolled patients with H. pylori infection without previous treatment. Patients were receiving a sequential therapy for either 10 or 14 days with esomeprazole 40 mg and amoxicillin 1 g (5 or 7 days) followed by esomeprazole 40 mg, clarithromycin 500 mg and tinidazole 500 mg (5 or 7 days), all given twice daily. Bacterial eradication was checked using 13C-urea breath test. Eradication cure rates were calculated at both Intention-to-treat (ITT) and per-protocol (PP) analyses.Results: A total of 291 patients were enrolled, including 146 patients in 10-day and 145 in the 14-day regimen. The eradication rates were 87% (95% CI = 81.5-92.4) and 90.3% (95% CI = 85.5-95.1) at ITT analysis with the 10- and 14-day regimen, respectively, and 92.7% (95% CI = 88.3-97) and 97% (95% CI = 94.2-99.9) at PP analysis (p =0.37). Among patients, who earlier had interrupted therapy, bacterial eradication was achieved in 8 out of 9 who completed the first therapy phase and performed at least ≥3 days of triple therapy in the second phase.Conclusion: This study found that both 10- and 14-day sequential therapies achieved a high eradication rate for first-line H. pylori therapy in clinical practice.

As high clarithromycin resistance (>20%) in the Split-Dalmatia region of Croatia hinders the treatment of H. pylori infection, the primary objective of this study was to compare concomitant quadruple with the tailored, personalized therapy as first-line eradication treatment of H. pylori. In an open-label, randomized clinical trial, 80 patients with H. pylori infection were randomly assigned to either concomitant (esomeprazole 40 mg, amoxicillin 1 gr, metronidazole 500 mg, clarithromycin 500 mg, twice daily for 14 days) or tailored therapy in accordance with the results of the antimicrobial susceptibility testing. Eradication status was assessed 4 weeks after treatment. Eradication rates were significantly higher in tailored group than in concomitant group both in intention-to-treat (70 vs. 92.5%, p = 0.010) and per-protocol (87.5 vs. 100%, p = 0.030) analysis in the setting of increasing antibiotic resistance (clarithromycin 37.5%, metronidazole 17.5%, dual resistance 10%). Adverse effects were more frequent in the concomitant group (32.5 vs. 7.5%, p = 0.006). Tailored therapy achieves higher eradication with a lower adverse events rate. With the increasing resistance of H. pylori strains to antibiotic treatment, eradication regimes with such characteristics should be strongly considered as a reasonable choice for first-line treatment.

This prospective study was to assess the efficacy of nonbismuth containing quadruple therapy as first-lineH. pyloritreatment and to determine the clinical factors influencing patient outcome. We enrolled 200H. pylori-infected naïve patients. They were prescribed either a 7-day nonbismuth containing quadruple therapy group (EACM, esomeprazole 40 mg twice daily, amoxicillin 1 g twice daily, metronidazole 500 mg twice daily, and clarithromycin 500 mg twice daily) or a 7-day standard triple therapy group (EAC, esomeprazole 40 mg twice daily, amoxicillin 1 g twice daily, and clarithromycin 500 mg twice daily). Follow-up studies to assess treatment responses were carried out 8 weeks later. The eradication rates attained by EACM and EAC groups were 95.6% (95% confidence interval [CI] = 89.4%–98.3%) and 79.3% (95% CI = 70%–86.4%) in the per-protocol analysis (P< 0.001) and 88% (95% CI = 80.2%–93.0%) and 73% (95% I = 63.6%–80.3%) in the intention-to-treat analysis (P= 0.007). Clarithromycin resistance, metronidazole resistance, and dual clarithromycin and metronidazole resistances were the clinical factors influencingH. pylorieradication in EACM group. Clarithromycin resistance and dual clarithromycin and metronidazole resistances were the influential factor for EAC treatment. In conclusion, the results suggest that 7-day nonbismuth containing quadruple therapy could achieve a grade “A” report card for first-lineH. pyloritreatment.

Helicobacter pylori eradication remains a challenge for physicians. Sequential, concomitant and the hybrid regimens have been proposed as novel, more effective therapies. We compare the efficacy of these therapies. Dyspeptic patients referred for upper endoscopy with H. pylori infection were enrolled. Patients were randomized to receive: (a) sequential therapy – 20 mg omeprazole and 1 g amoxicillin for 5 days, followed by 20 mg omeprazole, 500 mg clarithromycin and 500 mg tinidazole for the successive 5 days; (b) concomitant therapy – 20 mg omeprazole, 1 g amoxicillin, 500 mg clarithromycin and 500 mg tinidazole for either 5 days (5 day concomitant) or 14 days (14 day concomitant); or (c) hybrid therapy – 20 mg omeprazole and 1 g amoxicillin for 7 days, followed by 20 mg omeprazole, 1 g amoxicillin, 500 mg clarithromycin and 500 mg tinidazole for the successive 7 days. All drugs were given twice daily. Bacterial eradication was checked by using a [13C]urea breath test. In ‘intention-to-treat’ analysis, sequential therapy achieved the highest eradication rate, which was higher than that of 5 day concomitant therapy (90  vs 78.1 %; P = 0.02). The success rate did not statistically differ among the sequential and either 14 day concomitant (90  vs 86.3 %; P = not significant) or hybrid therapies (90  vs 82.7 %; P = not significant). The 10 day sequential, 14 day concomitant and 14 day hybrid therapies, but not the 5 day concomitant regimen, achieved similarly high eradication rates. The lower therapeutic cost coupled with the lower number of tablets needed would favour the sequential therapy as the first-line H. pylori treatment in clinical practice.
