Abstract
OBJECTIVES Furazolidone containing regimen is effectivefor Helicobacter pylori (H. pylori) infection, but its safetyremains controversial. To assess the safety of furazolidone containing regimenin H. pylori infection. DESIGN A systematic review and meta-analysis. DATA SOURCES PubMed, Embase, Cochrane Library, Web of Science and Scopus databases were systematically searched for eligible randomised controlled trials. ELIGIBILITY CRITERIA Studies comparing furazolidone with non-furazolidone-containing regimen, variable durations or doses of furazolidone were included. DATA EXTRACTION AND SYNTHESIS Two reviewers independently selected studies and extracted data. Primary outcomes were the risk of total adverse events (AEs), serious AEs and severe AEs, expressed as relative risk (RR) with 95% CI. Secondary outcomes contained the incidence of individual adverse symptoms, AE-related treatment discontinuation and compliance. RESULTS Twenty-six articles were identified from 2039 searched records, of which 14 studies (n=2540) compared furazolidone with other antibiotics. The eradication rates of furazolidone-containing regimen were higher than those of other antibiotics in both intention-to-treat (RR 1.06, 95% CI 1.01 to 1.12) and per-protocol analysis (RR 1.05, 95% CI 1.00 to 1.10). Only two serious AEs were reported in furazolidone group (2/1221, 0.16%). No significant increased risk was observed for the incidence of total AEs (RR 1.04, 95% CI 0.89 to 1.21) and severe AEs (RR 1.81, 95% CI 0.91 to 3.60). Twelve studies (n=3139) compared different durations of furazolidone, and four studies (n=343) assessed variable doses. Elevated risk of total AEs and severe AEs were only found in a high daily dose of furazolidone rather than prolonged duration. The incidence of AE-related treatment discontinuation and compliance of patients were all similar, irrespective of dose and duration adjustments. CONCLUSION Furazolidone-containing regimen has a similar risk of AEs and compliance as non-furazolidone-containing regimen. A low daily dose of 200 mg is well-tolerated for 14 day regimen and should be first considered. PROSPERO REGISTRATION NUMBER CRD42019137247.

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
Antibiotic resistance is a major cause of Helicobacter pylori (H. pylori) treatment failures. Because the resistance rate of H. pylori to furazolidone is low, we aimed to assess the efficacy and safety of furazolidone. We searched the PubMed, Web of Science, Cochrane Library, and Embase databases and included randomized controlled trials (RCT) that either compared furazolidone to other antibiotics or changed the administered dose of furazolidone. A total of 18 articles were included in the meta-analysis. According to the intention-to-treat (ITT) analysis, the total eradication rates of furazolidone-containing therapy were superior to those of other antibiotic-containing therapies (relative risk [RR] 1.07, 95% confidence interval [CI] 1.01-1.14) (13 RCTs). Specifically, the eradication rates of furazolidone-containing therapy were better than those for metronidazole-containing therapy (RR 1.10, 95% CI: 1.01-1.21 for ITT). The eradication rate of furazolidone-containing bismuth-containing quadruple therapy was 92.9% (95% CI: 90.7%-95.1%) (PP). In addition, a higher daily dose of furazolidone increased the eradication rate (RR 1.17, 95% CI: 1.05-1.31). And the incidence of some adverse effects, such as fever and anorexia, was higher in the furazolidone group than in the control group, the overall incidences of total side effects and severe side effects showed no significant differences between the groups. Furazolidone-containing treatments could achieve satisfactory eradication rates and did not increase the incidence of total or severe adverse effects, but the incidence of milder side effects, such as fever and anorexia, should be considered when prescribing furazolidone-containing treatments to patients.

Abstract
BACKGROUND The success rates of therapies for treating Helicobacter pylori vary greatly worldwide and the ideal treatment has yet to be clearly established. AIMS A systematic review was carried out to evaluate the effectiveness of current first and second-line therapies in treating H.pylori infection. METHODS Two researchers independently carried out Internet search engine reviews (PUBMED, EMBASE, MEDLINE) of clinical trials on adults published between 1990 and 2012 in both English and Spanish. RESULTS Forty-three (n=8,123) clinical trials were evaluated that included first and second-line triple, quadruple, and sequential therapies. The eradication rates of the standard triple therapy are unacceptable (≤80%) in countries where H.pylori is highly resistant to clarithromycin and metronidazole. Administration of the standard triple therapy for more than 7 days does not improve its effectiveness. No statistically significant differences were observed between the eradication rates of the quadruple therapy with bismuth and the standard triple therapy. Even though the sequential and concomitant therapies are equally successful regimens, the triple therapy with levofloxacin offers the best results as first and second-line treatment, but quinolone resistance can diminish its effectiveness. The triple therapy with levofloxacin and the sequential and concomitant treatments were superior to the standard triple regimen as first-line therapy. CONCLUSIONS Currently there is no ideal first or second-line treatment for achieving 100% eradication. The therapeutic order should be carried out according to the initial treatment and local antimicrobial resistance studies.

Abstract
UNLABELLED Failure of Helicobacter pylori treatment is a growing problem in daily practice. AIM To evaluate the efficacy of two new regimes as second-line options in a randomized and prospective study. METHODS Patients in whom a first eradication regime containing clarithromycin had failed were included. After performing gastroscopy and a 13C-urea breath test (UBT), the patients were randomized to receive a combination of 20 mg of rabeprazole, 500 mg of levofloxacin, and 200 mg (two tablets) of furazolidone administered once daily for 10 days (RLF) or the combination of 20 mg of rabeprazole, 120 mg (two tablets) of bismuth subcitrate, 100 mg of doxycycline, and 200 mg of furazolidone, administered twice daily for 10 days (RBDF). Clinical examinations and new UBT were performed 60 days after therapy. RESULTS Sixty patients were included (mean age, 46 years, 57% females). Two patients were excluded: one because of adverse effects and another as a result of protocol violation. Compliance was similar in both groups (90% took all medications correctly). Side-effects (96% mild) were observed in 87% of the patients and were comparable between groups, except diarrhea, which was more frequent in group RLF (p= .025). Intention-to-treat cure rates were 77% (95% confidence interval (CI): 62-93%) in the RLF group and 83% (95% CI: 68-97%) in the RBDF group (p= .750). Per-protocol cure rates were 80% (95% CI: 65-95%) in the RLF group and 82% (95% CI: 67-96%) in the RBDF group (p= 1.0). CONCLUSIONS Both once-daily triple (rabeprazole, levofloxacin, and furazolidone) and twice-daily quadruple therapy (rabeprazole, bismuth subcitrate, doxycycline, and furazolidone) for 10 days achieved encouraging results. Subsequent studies should be performed to evaluate antibiotic resistance, doses, dosing intervals, duration of treatment, and safety of these two regimes.

Abstract
AIM: To evaluate the patterns of use of clarithromycin for gastrointestinal disease treatment and promote its rational use.
METHODS: Using a structured pro forma, we conducted a two-month survey of the electronic prescriptions containing immediate-release (IR) or sustained-release (SR) product of clarithromycin for outpatients with gastrointestinal diseases in a 2200-bed general hospital. Suitability of the prescription was audited retrospectively.
RESULTS: One hundred and sixty-four prescriptions of SR product and 110 prescriptions of IR product were prescribed for gastrointestinal disease treatment. Among prescriptions for anti-Helicobacter pylori (H pylori) therapy, triple therapy take the dominant position (91.8%), followed by quadruple therapy (4.3%) and dual therapy (3.9%). Amoxicillin was the most frequently co-prescribed antibiotic. Furazolidone and levofloxacin are used more widely than metronidazole or tinidazole. Clarithromycin SR was administered at inappropriate time points in all prescriptions. Fifty percent of all prescriptions of clarithromycin SR, and 6.4% of prescriptions of clarithromycin IR, were prescribed at inappropriate dosing intervals. Surprisingly, disconcordance between diagnoses and indications was observed in all prescriptions of clarithromycin SR which has not been approved for treating H pylori infection although off-label use for this purpose was reported in literature. On the contrary, only one prescription (0.9%) of clarithromycin IR was prescribed for unapproved indication (i.e. gastro-oesophageal reflux disease). 1.4% of prescriptions for chronic gastritis or peptic ulcer treatment were irrational in that clarithromycin was not co-prescribed with gastric acid inhibitors. Clinical significant CYP3A based drug interactions with clarithromycin were identified.
CONCLUSION: There is a great scope to improve the quality of clarithromycin prescribing in patients with gastrointestinal disease, especially with regard to administration schedule, concordance between indications and diagnoses and management of drug interactions.

Abstract
Several aspects of Helicobacter pylori eradication have been meta-analyzed; however, nitrofuran-based therapies constitute an exception. The aim of this study was the systematic review and meta-analysis of the effect of furazolidone- and nitrofurantoin-based regimens in the eradication of infection. Studies evaluating the effects of nitrofurans on H. pylori were identified from Medline, EMBASE, the Cochrane Controlled Trials Register and congress abstracts. The studies were classified into groups based on first-, second- and third-line regimens. The pooled eradication rates and combined odd ratios of the individual studies were calculated and compared with the published meta-analysis. The factors influencing the efficiency of the regimens were also analyzed. Side-effects of nitrofuran-based regimens were also analyzed. The pooled eradication rate of primary proton pump inhibitor-based regimens containing furazolidone was 76.3% (CI 67.8-84.2). The odds ratio for furazolidone-based regimens versus standard triple therapies was 2.34 (CI 0.76-3.92). Ranitidine bismuth citrate + furazolidone-based triple regimens were equally efficient (83.5%, CI 74.0-93.0, P = 0.06 versus triple therapies). Schedules including a H(2) antagonist + furazolidone + one other antibiotic achieved pooled eradication rates of 79.9% (CI 67.8-89.9, P = 0.04). Bismuth-based triple therapies achieved 84.5% (CI 72.6-93.0, P = 0.002). Primary quadruple regimens containing furazolidone were superior to triple therapies (83.4%, CI 69.7-92.3, P = 0.01). Second-line schedules containing furazolidone obtained eradication rates of 76.1% (CI 66.4-85.0, P = 0.28 versus primary regimens). Third-line 'rescue' therapies were efficient in 65.5% of the cases (CI 56.3-75.5, P = 0.0001). Side-effects of the regimens containing furazolidone were more frequent than in standard therapies (P = 0.02). The combined odds ratio of side-effects for furazolidone-based versus standard therapies was 0.74 (CI 0.32-1.98). The duration of treatment, but not the furazolidone dose, influenced the treatment outcome. Primary triple regimens containing furazolidone are slightly less efficient than the standard primary combinations; primary quadruple regimens were more efficient than triple therapies. Furazolidone is also efficient as a component of second-line or rescue therapies.

Abstract
Clarithromycin extended-release (ER) is a second-generation macrolide with bactericidal activity against a broad group of pathogens. It allows for convenient once-daily dosing (2 x 500 mg/day), and has less severe adverse effects than the immediate-release (IR) formulation of the drug, which may result in improved patient compliance. Clarithromycin ER has been approved for the treatment of community-acquired pneumonia, acute maxillary sinusitis and acute bacterial exacerbation of chronic bronchitis. In comparison to the IR formulation, clarithromycin ER demonstrates prolonged absorption from the gastrointestinal tract, allowing for once-daily dosing with improved gastrointestinal tolerability. Various double-blind, randomised clinical trials and group studies have found clarithromycin ER to be an efficacious treatment option, comparable with clarithromycin IR, or its other competitors.

Abstract
BACKGROUND Primary antibiotic-resistance and poor compliance are the main causes of Helicobacter pylori eradication failure of standard regimens. AIM To investigate eradication rate, patient compliance and tolerability of a 1-week once-daily levofloxacin plus azithromycin triple therapy versus the standard twice-daily triple therapy. PATIENTS AND METHODS A total of 164 H. pylori-positive patients were randomised to either esomeprazole 20mg, levofloxacin 500 mg and azithromycin 500 mg once-daily (ELAz) or esomeprazole 20mg, clarithromycin 500 mg and amoxycillin 1g twice-daily (ECA) for 1 week. H. pylori infection was defined at entry by histology and urea breath test; cure of infection was determined both by negative urea breath test and H. pylori stool antigens. RESULTS H. pylori eradication rates of ELAz and ECA were similar at intention-to-treat (both 65%) and per-protocol analyses (70% versus 76%, respectively). Incidence of poor compliance was lower, although not significantly, in patients randomised to ELAz than to ECA (4% versus 10%); tolerability was significantly higher for ELAz than for ECA (88% versus 70%; P=0.01). CONCLUSIONS Once-daily levofloxacin plus azithromycin-based triple therapy achieves an H. pylori eradication rate comparable to that of standard twice-daily triple therapy, but is associated with higher patient compliance and might even be better tolerated.

Abstract
BACKGROUND Helicobacter pylori treatment failure is a growing problem in daily practice. AIM To determine the efficacy of the combination of rabeprazole, levofloxacin and furazolidone as a rescue therapy. METHODS Duodenal ulcer patients previously submitted, without success, to at least two H. pylori treatment regimens were included. Gastroscopy (urease test, histological examination and culture) and (13)C-urea breath test were performed. All patients received a combination of rabeprazole 20 mg, levofloxacin 500 mg and furazolidone 200 mg (two tablets) administered in a single dose in the morning for 10 days. Clinical examination and a new (13)C-urea breath test were performed 90 days after therapy. RESULTS Twelve patients (eight females and four males), mean age 43 (30-58) years were included. Two patients failed to complete the treatment because of nausea and vomiting. Ten patients completed the study and took all the medications as advised. Culture was obtained in six patients: 100 and 83% of the samples were sensitive to furazolidone and levofloxacin, respectively. Per-protocol and intention-to-treat eradication rates were 100 and 83% (P = 0.019). CONCLUSIONS the combination of rabeprazole, levofloxacin and furazolidone in a single daily dose for 10 days constitutes a highly-effective and low-cost alternative as a third-line therapy in patients infected with H. pylori.

Abstract
BACKGROUND Optimal management approach is not well defined for subjects who fail initial first- and second-line Helicobacter pylori eradication attempts and are dealt on a case-by-case basis by the specialists. AIM To evaluate the efficacy and safety of standard and 'rescue' eradication therapies at primary and secondary care levels. METHODS H. pylori infected dyspepsia patients referred to our C13 urea breath testing laboratory between January 1999 to February 2002 were included. Eradication failure at secondary care level was treated using strategies including antibiotic sensitivity testing and the use of rifabutin- and furazolidone-based therapies. RESULTS 3280 patients received standard first-line eradication therapy, which was successful in 2530 (77%) patients. Second-line therapy (bismuth-based 'quadruple') or triple therapy (altering constituent antibiotics) was successful in 56% of 270 treated patients. Subsequent eradication attempts using rifabutin-based (n = 34) and furazolidone-based (n = 10) regimens were successful in 38% and 60% patients respectively. H. pylori eradication rates were significantly different for guidelines compliant (94.8%) and non-compliant (82%) groups (P = 0.0001). H. pylori eradication rates for non-ulcer dyspepsia (40%) and peptic ulcer disease (36%) were not significantly different. CONCLUSIONS Available H. pylori eradication therapies remain very effective and compliance to guidelines achieves high success rates. Furazolidone-based 'rescue' regimen achieved high eradication rates after failure of the standard first-line, second-line and rifabutin-based therapies.

Abstract
BACKGROUND AND AIM Despite a similar Helicobacter pylori prevalence, peptic ulcer is more frequent in cirrhotic patients than in controls. We evaluated whether cirrhotic patients had an increased bacterial density and/or a higher prevalence of H. pylori cagA-positive strains than controls. METHODS A total of 36 dyspeptic cirrhotic patients with H. pylori infection and 72 matched controls were enrolled. H. pylori infection was detected at histology on Giemsa staining, bacterial density was assessed using difference over baseline (DOB) values at 13C urea breath test, and cagA status was established at serology. RESULTS Overall, both DOB values and prevalence of cagA did not significantly differ between cirrhotic patients and controls. However, peptic ulcer controls showed significantly higher DOB value (27.9 +/- 17.4 vs 19.4 +/- 9.3, respectively; P = 0.009) and cagA positive rate (85%vs 48%; P = 0.01) than non-ulcer dyspepsia patients. Although not statistically significant, a similar trend was observed in cirrhotic patients with peptic ulcer for DOB values (26.5 +/- 16.3 vs 18.3/1000 +/- 9.2, respectively; P = 0.07), whereas the cagA-positive rate was similar between peptic ulcer and non-ulcer dyspepsia patients (60%vs 50%; P = 0.30). CONCLUSIONS The present data showed that both bacterial density and cagA prevalence did not differ between cirrhotic patients and controls.

Abstract
OBJETIVO: Estudo multicêntrico, aberto, delineado para determinar a eficácia da associação de pantoprazol, claritromicina e amoxicilina, na erradicação do Helicobacter pylori em pacientes portadores de úlcera péptica. MATERIAL E MÉTODOS: Setenta e um pacientes (36 mulheres, 35 homens, idade média 41,9 anos) provenientes de três centros universitários brasileiros (Belo Horizonte e Porto Alegre) com úlcera péptica confirmada à endoscopia e infecção por H. pylori comprovada por, no mínimo, dois testes diagnósticos. Os pacientes foram tratados com a associação de pantoprazol 40 mg, claritromicina 500 mg e amoxicilina 1,0 g, administrada duas vezes ao dia, durante 7 dias. RESULTADOS: Ao final do tratamento, os pacientes foram reexaminados para avaliação dos sintomas gastrointestinais, presença de eventos adversos e aderência ao tratamento. Nova endoscopia com biopsias e teste respiratório com 13C-uréia foram repetidos 60 dias após o término do tratamento para determinação das taxas de erradicação do microrganismo. Foram considerados H. pylori negativos os pacientes com, pelo menos, o teste respiratório com 13C-uréia e mais um teste (teste da urease ou histologia) negativos. Ao final do estudo 60/69 (87%, 95% = 78,9-94,8) pacientes erradicaram o H. pylori na análise por protocolo e 60/71 (84,5%, 95% = 76-92,9) na análise por intenção de tratamento. Um paciente interrompeu o tratamento devido à diarréia. Doze pacientes (16,9%) apresentaram sintomas adversos e considerados de leve intensidade. CONCLUSÃO: A associação de pantoprazol, amoxicilina e claritromicina por 7 dias constitui alternativa eficaz e bem tolerada para a erradicação do H. pylori em portadores de úlcera péptica no Brasil.

Abstract
Review of the recently published data on Helicobacter pylori management highlights various interesting aspects. Current H. pylori eradication guidelines generally suggest a noninvasive 'test and treat' strategy for all dyspeptic patients with certain age limits depending on the local gastric neoplasia risk. According to the 'Maastricht 2-2000 Consensus Report' treatment should be thought of as a 'package' considering first- and second-line eradication therapies together. Various centres have published their results using novel antimicrobial formulations and 'rescue' and 'sequential' therapies. Review suggests that care at the specialist level remains a challenge and guidelines are deficient particularly as regards the selection and duration of eradication therapies. Results indicate that differences for CYP2C19 genotype and the selection of proton pump inhibitors have no significant role in determining eradication rates whereas antibiotic resistance and socio-economic factors play a variable role according to different geographical areas. Compliance remains an important factor in determining clinical outcome at the primary and secondary levels worldwide.
