| 1 | Resistance of Helicobacter pylori to antibiotics from 2000 to 2009 in Shanghai显示文摘AIM: To investigate the resistance of Helicobacter pylori (H. pylori ) to 6 commonly used antibiotics from 2000 to 2009 in Shanghai. METHODS: A total of 293 H. pylori strains were collected from 2000 to 2009 in Shanghai and tested for their susceptibility to metronidazole, clarithromycin, amoxicillin, furazolidone, levofloxacin and tetracycline using agar dilution. RESULTS: The resistant rates of H. pylori to clarithromycin (8.6%, 9.0% and 20.7%) and levofloxacin (10.3%, 24.0% and 32.5%) increased from 2000 to 2009 in Shanghai. The resistant rate of H. pylori to metronidazole remained stable (40%-50%). Only one strain of H. pylori isolated in 2005 was resistant to tetracycline. All strains were sensitive to amoxicillin and furazolidone.The resistant rate of H. pylori to antibiotics was not related with the sex, age and clinical outcome of patients. CONCLUSION: Resistance of H. pylori to antibiotics plays an important role in making treatment strategies against H. pylori -associated diseases. | Qin-Juan Sun Xiao Liang Qing Zheng Wei-Qi Gu WenZhong Liu Shu-Dong Xiao Hong Lu | 2010 | World Journal of Gastroenterology2010，16，40： | 90 |
| 2 | Furazolidone-based triple and quadruple eradication therapy for Helicobacter pylori infection显示文摘AIM: To evaluate the efficacy of furazolidone-based triple and quadruple therapy in eradicating Helicobacter pylori(H. pylori) in a multi-center randomized controlled trial.METHODS: A total of 720 H. pylori positive patients with duodenal ulcer disease were enrolled at 10 different hospitals in Jiangxi province in China. The patients were randomly assigned to four treatment groups as follows: patients in Groups 1 and 3 received rabeprazole(10 mg), amoxicillin(1000 mg) and furazolidone(100 mg) twice daily for 7 and 10 d, respectively; patients in Groups 2 and 4 received rabeprazole(10 mg), bismuth(220 mg), amoxicillin(1000 mg) and furazolidone(100 mg) twice daily for 7 and 10 d, respectively. The primary outcome measure was H. pylori eradication rate 4 wk after treatment by intention-to-treat and per protocol analysis, while the secondary outcome measures were symptom and sign changes at the end of treatment and 4 wk after the end of treatment, as well as the proportion of patients who developed adverse events.RESULTS: The demographic data of the four groups were not significantly different. Overall, 666 patients completed the scheme and were re-assessed with the 13C-urea breath test. The intention-to-treat analysis of the H. pylori eradication rates in Groups 1, 2, 3 and 4 were 74.44%, 82.78%, 78.89% and 86.11%, respectively. The H. pylori eradication rate in Group 4 was significantly higher than that in Group 1. According tothe per protocol analysis, the H. pylori eradication rates in Groups 1, 2, 3 and 4 were 81.21%, 89.22%, 85.54% and 92.26%, respectively. The H. pylori eradication rate in Group 4 was significantly higher than that in Group 1. The number of adverse events was 15(8.3%), 16(8.9%), 15(8.3%) and 17(9.4%) in Groups 1, 2, 3 and 4, respectively, including dizziness, vomiting, diarrhea, nausea, skin rash, itchy skin, and malaise. The symptoms were relieved without special treatment in all of the patients.CONCLUSION: Both 7- and 10-d quadruple furazolidone-based therapies achieve satisfactory H. pylori eradication rates. | Yong Xie Yin Zhu Hong Zhou Zhi-Fa Lu Zhen Yang Xu Shu Xiao-Bai Guo Hui-Zhen Fan Jian-Hua Tang Xue-Ping Zeng Jian-Bo Wen Xiao-Qing Li Xing-Xing He Jiu-Hong Ma Dong-Sheng Liu Cai-Bin Huang Ning-Jian Xu Nong-Rong Wang Nong-Hua Lu | 2014 | World Journal of Gastroenterology2014，20，32： | 24 |
| 3 | Outcomes of furazolidone-and amoxicillin-based quadruple therapy for Helicobacter pylori infection and predictors of failed eradication显示文摘AIM To evaluate the outcomes of furazolidone-and amoxicillin-based quadruple therapy for treatment of Helicobacter pylori(H. pylori) infection and identify predictors of failed eradication.METHODS Patients with H. pylori infection treated with furazolidone, amoxicillin, bismuth, and proton pump inhibitor therapy(January 2015 to December 2015) who received the ^(13)C-urea breath test > 4 wk after treatment were evaluated. Demographic and clinical data including prior H. pylori treatment attempts, medication adherence, alcohol and cigarette consumption during therapy, and treatment-related adverse events were recorded by reviewing medical records and telephone surveys. H. pylori eradication rates for overall and subgroups were evaluated. Multivariate analysis was performed to identify independent predictors of failed H. pylori eradication.RESULTS Of the 992 patients treated and retested for H. pylori infection, the overall eradication rate was 94.5% [95% confidence interval(CI): 94.1%-95.9%]. H. pylori eradication rate of primary therapy was 95.0%(95%CI: 93.5%-96.5%), while that of rescue therapy was 91.3%(95%CI: 86.8%-95.8%). Among the 859 patients who completed the study protocol, 144(17%) reported treatment-related adverse events including 24(3%) leading to premature discontinuation. On multivariate analysis, poor medication adherence [adjusted odds ratio(AOR) = 6.7, 95%CI: 2.8-15.8], two or more previous H. pylori treatments(AOR = 7.4, 95%CI: 2.2-24.9), alcohol consumption during therapy(AOR = 4.4, 95%CI: 1.5-12.3), and possibly smoking during therapy(AOR = 1.9, 95%CI: 0.9-4.3) were associated with failed H. pylori eradication. CONCLUSION Furazolidone-and amoxicillin-based quadruple therapy for H. pylori infection in an area with a high prevalence of clarithromycin resistance demonstrated high eradication rates as primary and rescue therapies with a favorable safety profile. Patient education targeting abstinence from alcohol during therapy and strict medication adherence may further optimize H. pylori eradication. | Ya-Wen Zhang Wei-Ling Hu Yuan Cai Wen-Fang Zheng Qin Du John J Kim John Y Kao Ning Dai Jian-Min Si | 2018 | World Journal of Gastroenterology2018，24，40： | 18 |
| 4 | Resistance of Helicobacter pylori to furazolidone and levofloxacin: A viewpoint显示文摘In their review, Arslan et al[1] did not describe the status of Helicobacter pylori(H. pylori) treatment with furazolidone and the resistance to this antibiotic. We have presented different surveys showing the resistance of H. pylori to furazolidone from Asia and South America. The resistance rates varied but were mostly low(< 5%). There are not enough data on its efficacy and resistance in the United States and Europe. H. pylori mutations occurring in the oor D gene, including A041 G, A122 G, C349A(G), A78 G, A112 G, A335 G, C156 T and C165 T, and in the por D gene, including G353 A, A356 G, C357 T, C347 T, C347 G and C346 A, have been indicated to be possibly related to the observed resistance. Additionally, to complete Arslan et al 's statement regarding levofloxacin resistance, it should be noted that compound mutations of N87 A, A88 N and V65 I at codon Asn-87 were recently observed in the gyr A gene for the first time. However, the results on these topics are not sufficient, and more worldwide studies are suggested. | Mohammad Zamani Arash Rahbar Javad Shokri-Shirvani | 2017 | World Journal of Gastroenterology2017，23，37： | 10 |
| 5 | Quadruple therapy for eradication of Helicobacter pylori显示文摘AIM:To investigate quadruple therapy with rabeprazole,amoxicillin,levofloxacin and furazolidone for the eradication of Helicobacter pylori (H.pylori) infection.METHODS:A total of 147 patients were divided into the experimental treatment group (n=78) and the standard triple treatment group (n=69).The experimental treatment group received rabeprazole 20 mg,amoxicillin 1.0 g,levofloxacin 0.2 g and furazolidone 0.1 g,twice daily.The standard triple treatment group received omeprazole 20 mg,amoxicillin 1.0 g and clarithromycin 0.5 g,twice daily.RESULTS:One month after treatment,the 13 C urea breath test was carried out to detect H.pylori.The eradication rate using per-protocol analysis was 94.3% in the experimental treatment group and 73% in the standard triple treatment group (P < 0.05),and using intention to test analysis,these figures were 86% and 67% in the two groups,respectively.Side effects were observed in 34 patients,and included mild dizziness,nausea,diarrhea and increased bowel movement.Eleven of the 34 patients needed no treatment for their side effects.CONCLUSION:Rabeprazole,amoxicillin,levofloxacinand furazolidone quadruple therapy is a safe method for the eradication of H.pylori with high efficacy and good tolerability. | Hai-Jun Ma Jin-Liang Wang | 2013 | World Journal of Gastroenterology2013，19，6： | 5 |
