A Comparison of Doxycycline and Amoxicillin Containing Quadruple Eradication Therapy for Treating Helicobacter pylori-Infected Duodenal Ulcers: A Multicenter, Opened, Randomized Controlled Trial in China. Pathogens 2022; 11:pathogens11121549. [PMID: 36558883 PMCID: PMC9783029 DOI: 10.3390/pathogens11121549] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 11/28/2022] [Accepted: 12/14/2022] [Indexed: 12/23/2022] Open
Abstract
Background: Increased antibiotic resistance is one of the major factors contributing to the failure of H. pylori eradication. This study aimed to compare the efficacy and safety of doxycycline and amoxicillin, both critical components for bismuth-based quadruple therapy, for the first-line treatment of H. pylori-infected duodenal ulcers. Methods: An open, randomized case-controlled, multicenter trial was conducted in seven hospitals in China. A total of 184 eligible participants were divided into an IDFB (ilaprazole 5 mg, doxycycline 100 mg, furazolidone 100 mg, and bismuth 220 mg bid) or IAFB (ilaprazole 5 mg, amoxicillin 1000 mg, furazolidone 100 mg, and bismuth 220 mg bid) group for 14 days. Both groups were administrated with ilaprazole 5 mg qd for another 14 days. The main outcome was an H. pylori eradication rate; secondary outcomes were ulcer healing, relief of symptoms, and incidence of adverse effects. Results: The H. pylori eradication rates were 85.9% (95% CI 78.6−93.9) in the IDFB vs. 84.8% (95% CI 77.3−92.3) in the IAFB group in ITT analysis (p > 0.05), and 92.9% (95% CI 87.4−98.5) vs. and 91.8% (95% CI 85.8−97.7) in PP analysis (p > 0.05). The overall ulcer healing rates of IDFB and IAFB were 79.1% and 84.7% (p > 0.05), both effective in relieving symptoms. Only nine participants had adverse reactions in this trial (4/92 in IDFB and 5/92 in IAFB). Conclusion: A bismuth quadruple regimen containing doxycycline or amoxicillin could be an effective and safe treatment for H. pylori eradication, while doxycycline replacement is an alternative for participants with penicillin allergy.

Abstract
BACKGROUND Bismuth has antimicrobial activity and can improve the efficacy of triple Helicobacter pylori (H. pylori) therapy. Allicin added to conventional therapy for H. pylori infection also improves H. pylori eradication rates. Thus, this study aims to evaluate and compare the efficacy, safety and tolerability of allicin-containing quadruple therapy and bismuth-containing quadruple therapy and to investigate the factors that affect the eradication rates. METHODS Two hundred twenty H. pylori-infected patients were included and randomly (1:1) assigned to 14-day quadruple therapy: ilaprazole (5 mg bid), doxycycline (100 mg bid), and furazolidone (100 mg bid) with an allicin soft capsule (40 mg of DATS tid) (IDFA) or colloidal bismuth tartrate (220 mg of elemental bismuth bid) (IDFB). Eradication was confirmed by urea breath tests. Symptom improvement, adverse events, and adherence were assessed by a questionnaire. RESULTS In the intention-to-treat and per-protocol analysis, the eradication rates for IDFA and IDFB groups were 87.5% (70/80) vs. 86.3% (69/80, P = 0.815) and 91.9% (68/74) vs. 91.8% (67/73, P = 0.980) as first-line therapies; 83.3% (25/30) vs. 83.3% (25/30, P = 1) and 89.3% (25/28) vs. 88.9% (24/27, P = 1) as second-line therapies. Symptom improvement rates were 96.1% and 97.0% for IDFA and IDFB (P = 1). The adverse event rates were 10.9% in IDFA and 14.5% in IDFB groups (P = 0.418). Nausea occurred frequently in IDFB than IDFA (1.8% vs. 8.2%, P = 0.030). Smoking and sharing utensils significantly affected the efficacy. CONCLUSION Allicin-containing quadruple therapy might be regarded as a promising alternative to bismuth-containing quadruple therapy in H. pylori eradication.

Abstract
BACKGROUND Different bismuth quadruple therapies containing proton-pump inhibitors, bismuth salts, metronidazole, and a tetracycline have been recommended as third-line Helicobacter pylori eradication treatment after failure with clarithromycin and levofloxacin. AIM To evaluate the efficacy and safety of third-line treatments with bismuth, metronidazole, and either tetracycline or doxycycline. METHODS Sub-study with Spanish data of the "European Registry on H pylori Management" (Hp-EuReg), international multicenter prospective non-interventional Registry of the routine clinical practice of gastroenterologists. After previous failure with clarithromycin- and levofloxacin-containing therapies, patients receiving a third-line regimen with 10/14-day bismuth salts, metronidazole, and either tetracycline (BQT-Tet) or doxycycline (BQT-Dox), or single capsule (BQT-three-in-one) were included. Data were registered at AEG-REDCap database. Univariate and multivariate analyses were performed. RESULTS Four-hundred and fifty-four patients have been treated so far: 85 with BQT-Tet, 94 with BQT-Dox, and 275 with BQT-three-in-one. Average age was 53 years, 68% were women. Overall modified intention-to-treat and per-protocol eradication rates were 81% (BQT-Dox: 65%, BQT-Tet: 76%, BQT-three-in-one: 88%) and 82% (BQT-Dox: 66%, BQT-Tet: 77%, BQT-three-in-one: 88%), respectively. By logistic regression, higher eradication rates were associated with compliance (OR = 2.96; 95% CI = 1.01-8.84) and no prior metronidazole use (OR = 1.96; 95% CI = 1.15-3.33); BQT-three-in-one was superior to BQT-Dox (OR = 4.46; 95% CI = 2.51-8.27), and BQT-Tet was marginally superior to BQT-Dox (OR = 1.67; 95% CI = 0.85-3.29). CONCLUSION Third-line H pylori eradication with bismuth quadruple treatment (after failure with clarithromycin and levofloxacin) offers acceptable efficacy and safety. Highest efficacy was found in compliant patients and those taking 10-day BQT-three-in-one or 14-day BQT-Tet. Doxycycline seems to be less effective and therefore should not be recommended.

Bovine lactoferrin enhances the efficacy of levofloxacin-based triple therapy as first-line treatment of Helicobacter pylori infection: an in vitro and in vivo study. J Antimicrob Chemother 2020; 74:1069-1077. [PMID: 30668729 PMCID: PMC6419617 DOI: 10.1093/jac/dky510] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2018] [Revised: 10/24/2018] [Accepted: 11/12/2018] [Indexed: 12/11/2022] Open
Abstract
Objectives To evaluate the in vitro antimicrobial/antivirulence action of bovine lactoferrin and its ability to synergize with levofloxacin against resistant Helicobacter pylori strains and to analyse the effect of levofloxacin, amoxicillin and esomeprazole with and without bovine lactoferrin as the first-line treatment for H. pylori infection. Methods The bovine lactoferrin antimicrobial/antivirulence effect was analysed in vitro by MIC/MBC determination and twitching motility against six clinical H. pylori strains and a reference strain. The synergism was evaluated using the chequerboard assay. The prospective therapeutic trial was carried out on two separate patient groups, one treated with esomeprazole/amoxicillin/levofloxacin and the other with esomeprazole/amoxicillin/levofloxacin/bovine lactoferrin. Treatment outcome was determined with the [13C]urea breath test. Results In vitro, bovine lactoferrin inhibited the growth of 50% of strains at 10 mg/mL and expressed 50% bactericidal effect at 40 mg/mL. The combination of levofloxacin and bovine lactoferrin displayed a synergistic effect for all strains, with the best MIC reduction of 16- and 32-fold for levofloxacin and bovine lactoferrin, respectively. Bovine lactoferrin at one-fourth MIC reduced microbial motility significantly for all strains studied. In the in vivo study, 6 of 24 patients recruited had treatment failure recorded with esomeprazole/amoxicillin/levofloxacin (75% success, 95% CI 57.68%–92.32%), and in the group with esomeprazole/amoxicillin/levofloxacin/bovine lactoferrin, 2 out of 53 patients recruited had failure recorded (96.07% success, 95% CI 90.62%–101.38%). Conclusions Bovine lactoferrin can be considered a novel potentiator for restoring susceptibility in resistant H. pylori strains. Bovine lactoferrin added to a triple therapy in first-line treatment potentiates the therapeutic effect.

Abstract
GOALS The goal of this study was to examine the impact of prior treatment with a nitroimidazole antibiotic on the success of Helicobacter pylori treatment. BACKGROUND Prior nitroimidazole exposure may increase the likelihood of nitroimidazole-resistant H. pylori. Current H. pylori treatment guidelines recommend that, in the absence of susceptibility testing, patients with prior nitroimidazole exposure should not be treated with a nitroimidazole antibiotic. Data to support this recommendation are lacking. STUDY We searched the Clalit Health Services database to identify subjects 25 to 60 years old who underwent a first-ever C-urea breath test between 2010 and 2015. Patients who underwent a previous H. pylori stool antigen test or gastroscopy were excluded. Pharmacy dispensation data were retrieved. RESULTS A total of 1386 subjects (34.8% male individuals, age 40.7±10.7 y) received a nitroimidazole-containing regimen including 282 (20.4%) with prior nitroimidazole exposure. Successful eradication was achieved in 58.9% and 73.8% of subjects with and without prior nitroimidazole exposure, respectively (odds ratio, 0.51; 95% confidence interval, 0.39-0.67; P<0.0001). Nitroimidazole exposure adversely impacted the success of triple therapy with nitroimidazole, proton pump inhibitor, and amoxicillin or clarithromycin (39.4% vs. 63.4% and 54.4% vs. 73.6%, P<0.01, respectively), but not quadruple therapy. Following multivariate analysis, nitroimidazole exposure was significantly associated with eradication failure (odds ratio, 1.89; 95% confidence interval, 1.43-2.50; P<0.0001). A greater time elapsed from nitroimidazole exposure, and a lower cumulative nitroimidazole dose were observed in subjects with successful eradication (P<0.0001 for both). CONCLUSION Nitroimidazole exposure may adversely impact the success of nitroimidazole-based triple therapy, but not quadruple therapy. Clinicians should conduct a thorough patient drug history before administering empiric treatment for H. pylori infection.

Abstract
BACKGROUND Bismuth-containing quadruple therapy (BQT) is a recommended alternative first-line therapy for Helicobacter pylori (H. pylori) infection. We aim to evaluate the efficacy and safety of a new BQT with amoxicillin and doxycycline as a first-line treatment for H. pylori infection in clinical practice. METHODS An open, prospective pilot clinical study including H. pylori-positive outpatients who had never received eradication treatment was carried out. An RADB regimen (10 mg rabeprazole, 1000 mg amoxicillin, 100 mg doxycycline, and 220 mg colloidal bismuth tartrate, all given bid for 14 days) was prescribed by gastroenterologists. H. pylori eradication was confirmed by a 13 C-urea breath test performed at least 6 weeks after the end of treatment. Regimen efficacy was evaluated by per-protocol (PP) and intention-to-treat (ITT) analyses. RESULTS One hundred eighteen patients were included in the study. The eradication rate of RADB was 93.8% (105/112; 95% CI 89.2%-98.3%) in PP analysis and 89.8% (106/118; 95% CI 84.3%-95.4%) in ITT analysis. The patient compliance rate was 97.5% (115/118). The adverse event rate was 6.8% (8/118). Adverse events included asthenia, loss of appetite, dry mouth, heartburn, diarrhea, and abdominal pain. All adverse events disappeared after completion of therapy. CONCLUSION Our results suggest that 14-day BQT with amoxicillin and doxycycline can be an effective and safe eradication regimen for first-line therapy against H. pylori infection in clinical practice.

Abstract
BACKGROUND The efficacy of Helicobacter pylori (H. pylori) eradication has steadily declined, primarily because of antibiotic resistance. This study aimed to evaluate the efficacy and safety of furazolidone eradication therapies as initial treatments for H. pylori infection. METHODS A national, multicenter, open-label, randomized controlled trial was performed at 16 sites across 13 provinces in China to evaluate the efficacy and safety of furazolidone-containing therapies for H. pylori infection. Treatment naïve patients were randomly assigned to: esomeprazole 20 mg, bismuth 220 mg, amoxicillin 1000 mg, and furazolidone 100 mg twice daily for 10 and 7 days (FAB 10 and FAB 7; the same therapy without bismuth (FA 10 and FA 7). The primary and secondary outcomes were the eradication rate and regimen safety, respectively. Treatment success was assessed by the 13 C urea breath test at least 4 weeks after treatment completion. RESULTS Overall, according to intention-to-treat (ITT) analysis, the eradication rates for FAB 10 and FAB 7 were 86.6% (95% confidence interval [CI], 79.9%-93.2%) and 83.6% (95% CI, 76.3%-90.9%) and for FA 10 and FA 7 were 82.4% (95% CI, 74.9%-89.8%) and 77.6% (95% CI, 69.4%-85.8%), respectively. According to per-protocol analysis, the overall eradication rates for FAB 10 and FAB 7 were 94.7% (95% CI, 90.3%-99.1%) and 90.8% (95% CI, 85.1%-96.5%) and for FA 10 and FA 7 were 90.6% (95% CI, 84.9%-96.3%) and 85.1% (95% CI, 78.2%-92.1%), respectively. The overall prevalence of side effects was 8.1%. CONCLUSIONS Furazolidone-containing therapies, particularly the tested 10-day quadruple therapy, exhibited satisfactory efficacy and safety. This 10-day quadruple therapy represents a promising initial treatment strategy for Chinese patients.

Abstract
OBJECTIVE Helicobacter pylori (H. pylori) infection is difficult to cure, mainly due to antibiotic resistance. This study aimed to determine the efficacy and safety of 7-day bismuth-containing concomitant quintuple regimen for H. pylori eradication. METHODS Conducted from August 2015 to February 2016 at the First Affiliated Hospital of Nanchang University, this prospective trial enrolled 70 untreated patients who were positive for H. pylori. The patients received 7-day quintuple therapy consisting of bismuth subcitrate 220 mg, esomeprazole 20 mg, clarithromycin 500 mg, amoxicillin 1 g and metronidazole 400 mg, each was given twice daily. All patients underwent a 13 C-urea breath test at 4 weeks after treatment. RESULTS A total of 70 patients at a mean age of 43.5 years, including 36 men, were included in this trial. One person who violated the protocol was further excluded. The treatment compliance rate was 99.6%. The overall eradication rates of the 7-day bismuth-containing concomitant quintuple therapy were 75.4% (intention-to-treat analysis) and 86.7% (per-protocol analysis). The prevalence of side effects was 31.9%, including a bitter taste (23.2%), nausea (4.3%), dizziness (2.9%), diarrhea (2.9%), limb asthenia (2.9%), skin rash (1.4%), numbness of the tip of the tongue (1.4%) and insomnia (1.4%). CONCLUSIONS The 7-day bismuth-containing concomitant quintuple therapy may not be superior to traditionally widely accepted therapy due to its lack of acceptable efficacy and high rate of side effects.

Abstract
Many interesting articles have been published from different parts of the world over the last year assessing various issues around Helicobacter pylori eradication therapy. This article will address the published literature over the last year pertaining to the topic of treatment of H. pylori infection. The main themes that emerge are assessing the efficacy of standard triple therapy, as well as exploring new first-line treatments, mainly optimized nonbismuth-containing and bismuth-containing quadruple therapies with some promising data also emerging on dual therapy. There was also considerable progress in investigating antibiotic resistance rates with much more data emerging from varied parts of the world compared to recent years. Advances in the use of adjunctive therapies, especially probiotic therapies have also been made. Undoubtedly, the eradication of H. pylori remains a worthwhile goal to alleviate the burden of diseases caused by the complications of this infection, including dyspepsia, peptic ulcer disease, and gastric cancer.

Abstract
Helicobacter pylori (H. Pylori) is a leading cause of gastroduodenal disease, including gastric cancer. H. pylori eradication therapies and their efficacy are summarized. A number of current treatment regimens will reliably yield >90% or 95% cure rates with susceptible strains. None has proven to be superior. We show how to predict the efficacy of a regimen in any population provided one knows the prevalence of antibiotic resistance. As with other infectious diseases, therapy should always be susceptibility-based. Susceptibility testing should be demanded. We provide recommendations for empiric therapies when that is the only option and describe how to distinguish studies providing misinformation from those providing reliable and interpretable data. When treated as an infectious disease, high H. pylori cure rates are relatively simple to reliably achieve.

Abstract
Over three decades have passed since the discovery of Helicobacter pylori (H. pylori), and yet many questions about its treatment remain unanswered. For example, there is no certainty regarding continued use of current antibiotic therapy against H. pylori. The bad news is that even combined regimens are also unable to eradicate bacterial colonization. The worst problem with H. pylori chemotherapy is that even if we identify the most successful regimen, it cannot eliminate the risk of re-infection. This problem is further complicated by the fact that clinicians have no information as to whether probiotics are useful or not. Moreover, to date, we have no large scale produced vaccine effective against H. pylori. Due to the relatively rapid and abundant dissemination of guidelines globally reported concerning management of gastric cancer prevention and therapeutic regimens, clinicians may choose a vaccine as better effective weapon against H. pylori. Therefore, a radical shift in adopted strategies is needed to guide ultimate decisions regarding H. pylori management. In light of failures in vaccine projects, we should identify better vaccine design targeting conserved/essential genes. The unique character and persistence of H. pylori pose obstacles to making an effective vaccine. Preferably, in developing countries, the best reasonable and logical approach is to recommend prophylactic H. pylori vaccine among children as an obligatory national program to limit primary colonization. Trying to produce a therapeutic vaccine would be postponed until later. In reality, we should not forget to prescribe narrow spectrum antibiotics. In the current review, I draw a route to define the best adopted strategy against this rogue bacterium.

Abstract
OBJECTIVE Helicobacter pylori expresses an increased resistance in respect to antimicrobials currently used in therapy. The aim of this study was to evaluate the antimicrobial profiles of H. pylori isolates to nine conventional antibiotics used in a Central Region (Abruzzo) of Italy. MATERIALS AND METHODS Biopsies were taken from antrum and fundus of 112 adult and 3 children with Urea Breath Test positive with dyspeptic symptoms and analyzed for H. pylori culture and antibacterial activity. Antimicrobial susceptibility tests were performed for clarithromycin, metronidazole, levofloxacin, moxifloxacin, ciprofloxacin, tetracycline, amoxicillin, ampicillin, and rifabutin by a modified agar dilution susceptibility test. RESULTS Bacterial culture was successful in 100 out of 115 patients. Helicobacter pylori strains were isolated from 98 antrum and 83 fundus samples. The rate of recovery of H. pylori strains was 90.50% (181/200). The percentages of resistance were as follows: clarithromycin 72.44% antrum, 72.28% fundus; metronidazole 34.69% antrum, 42.16% fundus; levofloxacin 42.85% antrum, 53.01% fundus; moxifloxacin 37.35% antrum, 46.57% fundus; ciprofloxacin 39.47% antrum, 44.28% fundus; tetracycline 2.63% antrum, 2.85% fundus; amoxicillin 1.02% antrum, 1.20% fundus; ampicillin 0% antrum and fundus and rifabutin 0% antrum, 1.20% fundus. A total of 35 subjects harbored multi-resistant strains. CONCLUSIONS This study underlines the high rate of resistance to clarithromycin, metronidazole and quinolones, which may reflect an overuse of them. Culture and susceptibility test, should be performed to prevent the emergence of multi-resistance and to assess an efficacious regimen.

Abstract
Bismuth triple therapy was the first effective Helicobacter pylori eradication therapy. The addition of a proton pump inhibitor helped overcome metronidazole resistance. Its primary indication is penicillin allergy or when clarithromycin and metronidazole resistance are both common. Resistance to the primary first-line therapy have centered on complexity and difficulties with compliance. Understanding regional differences in effectiveness remains unexplained because of the lack of studies including susceptibility testing and adherence data. We discuss regimen variations including substitutions of doxycycline, amoxicillin, and twice a day therapy and provide suggestions regarding what is needed to rationally and effectively use bismuth quadruple therapy.
