Introduction: Helicobacter pylori eradication remains a problematic issue. We are in an urgent need for finding a treatment regimen that achieves eradication at a low cost and less side effect. Recent published results showing a high rate of resistance and with clarithromycin-based treatment regimens. The aim of the study was to compare moxifloxacin therapy and classic clarithromycin triple therapy in H. pylori eradication. Methods: This was a pilot study that enrolled 60 patients with helicobacter pylori associated gastritis. Diagnosis was done by assessment of H. pylori Ag in the stool. The patients were randomly assigned to receive either moxifloxacin based therapy (Group A), or clarithromycin based therapy (Group B) for two weeks. We stopped the treatment for another two weeks then reevaluation for cure was done. Results: 90 % of patients had negative H. pylori Ag in the stool after 2 weeks of stoppage of the treatment in group A versus 66.7 % in Group B. None of the patients in both groups had major side effects. Conclusion: Moxifloxacin-based therapy showed higher eradication power and less resistance when compared to clarithromycin triple therapy.

Current clinical treatment of Helicobacter pylori infection, the main etiological factor in the development of gastritis, gastric ulcers, and gastric carcinoma, requires a combination of at least two antibiotics and one proton pump inhibitor. However, such triple therapy suffers from progressively decreased therapeutic efficacy due to the drug resistance and undesired killing of the commensal bacteria due to poor selectivity. Here, we report the development of antimicrobial polypeptide-based monotherapy, which can specifically kill H. pylori under acidic pH in the stomach while inducing minimal toxicity to commensal bacteria under physiological pH. Specifically, we designed a class of pH-sensitive, helix–coil conformation transitionable antimicrobial polypeptides (HCT-AMPs) (PGA)m-r-(PHLG-MHH)n, bearing randomly distributed negatively charged glutamic acid and positively charged poly(γ-6-N-(methyldihexylammonium)hexyl-l-glutamate) (PHLG-MHH) residues. The HCT-AMPs showed unappreciable toxicity at physiological pH when they adopted random coiled conformation. Under acidic condition in the stomach, they transformed to the helical structure and exhibited potent antibacterial activity against H. pylori, including clinically isolated drug-resistant strains. After oral gavage, the HCT-AMPs afforded comparable H. pylori killing efficacy to the triple-therapy approach while inducing minimal toxicity against normal tissues and commensal bacteria, in comparison with the remarkable killing of commensal bacteria by 65% and 86% in the ileal contents and feces, respectively, following triple therapy. This strategy renders an effective approach to specifically target and kill H. pylori in the stomach while not harming the commensal bacteria/normal tissues.

BACKGROUND: Optimal anti-Helicobacter pylori treatment has not yet been established. AIM: To evaluate H. pylori eradication using tetracycline and furazolidone versus amoxicillin and azithromycin in lansoprazole based triple therapy in northeastern of Brazil. PATIENTS AND METHODS: One hundred and four patients with H. pylori infection, as determined by rapid urease testing and histology, were randomly assigned to receive either: lansoprazole (30 mg q.d.), tetracycline (500 mg q.i.d.), and furazolidone (200 mg t.i.d.) for 7 days (LTF; n = 52); or lansoprazole (30 mg b.i.d.) and amoxicillin (1 g b.i.d.) for 1 week, plus azithromycin (500 mg q.d.) for the first 3 days (LAAz; n = 52). H. pylori eradication was assessed 3 months following completion of therapy by means of rapid urease testing, histology and a 14C-urea breath test. RESULTS: H. pylori eradication was achieved in 46 of 52 (88.4%, 95% CI: 77.5%-95.1%) patients in LTF group and in 14 of 52 (26.9%, 95% CI: 16.2%-40,1%) patients in LAAz group. On a per-protocol analysis, eradication rates were 91.8% (95% CI: 81.4%-97.3%) and 28.5% (95% CI: 17.2%-42.3%), respectively in LTF and LAAz groups. CONCLUSION: The LAAz regimen yielded unacceptably low eradication rates. On the other hand, the LTF scheme represents a suitable alternative for H. pylori eradication.

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.

Objective. To assess efficacy and safety of 14-day triple nifuratel-based therapy compared to 14-day standard triple therapy in adult patients with symptomatic H. pylori infection. Materials and Methods. A total of 70 patients with dyspepsia and microbiologically confirmed H. pylori infection were enrolled into the open-label, randomized, comparative clinical trial. The study group (n = 35) received a 14-day triple nifuratel-based therapy: esomeprazole (20 mg BID), nifuratel (400 mg BID) and amoxicillin (1000 mg BID). The comparator group (n = 35) received 14-day conventional clarithromycinbased triple therapy: esomeprazole (20 mg BID), clarithromycin (500 mg BID) and amoxicillin (1000 mg BID). Eradication of H. pylori was assessed using stool antigen test. Results. Eradication rates for 14-day nifuratel-based triple therapy and 14-day clarithromycin-based triple therapy in the intent-to-treat (ITT) population were 82.9% and 74.3% (p = 0.561), respectively. In the per-protocol (PP) population, eradication rates were 90.6% and 89.7% (p = 1.00), respectively. Adverse events were reported in 17.1% of patients in the study group and 34.3% of patients in the comparator group (p > 0.05). Conclusions. The 14-day triple nifuratel-based therapy has demonstrated a high H. pylori eradication rate (above 90%). Nifuratel triple therapy may be considered as an alternative to clarithromycin-based triple therapy for patients with a history of the prior macrolide exposure or macrolide intolerance.

Aim. Evaluation of the efficacy and safety of quadrupletherapy without bismuth (concomitant therapy) in patients with Helicobacter pylori - associated gastric ulcer and duodenal ulcer in the framework of a comparative research in the population of patients in Russia. Materials and methods. A prospective randomized trial was conducted, which included 210 patients with H. pylori - associated gastric/duodenal ulcer without complications. During the process of randomization, the patients were divided into three equal groups (n=70) depending on the prescribed 10-day scheme of eradication therapy (ET): the first group received the classic triple scheme (Omeprazole 20 mg 2 times a day, Amoxicillin 1000 mg 2 times a day and Clarithromycin 500 mg 2 times a day); the second group received quadruple therapy with bismuth drugs (Omeprazole 20 mg 2 times a day, Tetracycline 500 mg 4 times a day, Metronidazole 500 mg 3 times a day, Bismuth subcitrate potassium 120 mg 4 times a day); the third group received quadruple therapy without bismuth - concomitant therapy (Omeprazole 20 mg 2 times a day, Amoxicillin 1000 mg 2 times a day, Clarithromycin 500 mg 2 times a day and Metronidazole 500 mg 2 times a day). Diagnostics of H. pylori infection during screening and control of eradication was carried out via the fast urease biopsy sample test and urea breath test system. Control of the effectiveness of ET of the microorganism was carried out not earlier than 4 weeks after the end of the treatment. During the course of therapy, the frequency of development of side effects was assessed using a special questionnaire. Results and discussion. The effectiveness of triple therapy was 72.8% (ITT; 95% CI of 62.17-83.54) and 78,4% (PP; 95% CI 68.19-88.72); quadruple therapy with the preparation of bismuth - 80.0% (ITT; 95% CI 70.39-89.6) and 84,8% (PP; 95% CI, 75.96-93.73); quadruple therapy without bismuth - concomitant therapy - 84.2% (ITT; 95% CI 75.54-93.02) and 92.1% (PP; 95% CI 85.43-98.94). Quadruple therapy without bismuth was reliably more effective than the classical triple therapy in the PP selection (p=0.044883). Statistical analysis showed a tendency to poorer effectiveness of ET in patients who had previously used antibiotic therapy (OR 0.4317; 95% CI 0.1776-1.049), and in individuals with a rapid metabolism genotype - CYP2C19*1/*1 (OR 0.12; 95% CI 0.005848-2.4624). The frequency of development of side effects during the use of triple therapy was 18.5% (95% CI of 9.23-27.91), when using quadruple therapy with bismuth - 20.0% (95% CI 10.39-29.6), and with the use of quadruple therapy without bismuth - concomitant therapy - 24.2% (95% CI 13.98-34.58). Conclusion. This prospective randomized study demonstrated the high efficiency of quadruple therapy without bismuth (concomitant therapy) in the framework of eradication of H. pylori infection in Russia.
