METHODS Major literature databases(Pub Med, EMBASE and the Cochrane Central Register of Controlled Trials) were searched for relevant articles published prior to February 2018. We performed a meta-analysis of all randomized clinical trials that examined the efficacy of h. pylori eradication therapies and included fourthgeneration quinolones in the experimental arm. Subgroup analyses by regions and different types of fourth-generation quinolones were also performed.RESULTS Ten studies including a total of 2198 patients were assessed. A meta-analysis of randomized controlled trials showed that the eradication rate of therapies containing non-fourth-generation quinolones was significantly lower than that of therapies containing fourth-generation quinolones by intention-to-treat(ITT) analysis [75.4% vs 81.8%; odds ratio(OR) = 0.661; 95% confidence interval(CI): 0.447-0.977; P = 0.038]. This analysis also showed that the eradication rate of the therapies containing non-fourth-generation quinolones was inferior to that of therapies containing fourth-generation quinolones by perprotocol analysis(79.1% vs 84.7%; OR = 0.663; 95%CI: 0.433-1.016; P = 0.059). Moreover, the occurrence of side effects was significantly different between the control and experimental groups by ITT analysis(30.6% vs 19.5%; OR = 1.874; 95%CI: 1.120-3.137; P = 0.017). The sub-analyses also showed significant differences in moxifloxacin therapies vs other fourth-generation quinolone therapies(84.3% vs 71.9%) and in Asian vs European groups(76.7% vs 89.1%).CONCLUSION Therapies containing fourth-generation quinolones achieved a poor eradication rate in the treatment of h. pylori infection. Such regimens might be useful as a rescue treatment based on antimicrobial susceptibility testing. Different antibiotics should be chosen in different regions.展开更多

Among 200 patients assessed in this study, 49 had received PIPC/TAZ and 151 4th Cephs. Patient background characteristics were comparable between the two treatment groups. The overall efficacy rate in those receiving 4th Cephs and PIPC/TAZ was 57.0% (86/151 patients) and 59.2% (29/49 patients), respectively, with no significant difference detected between the two treatment regimens (P = 0.78). Treat-ment did not need to be discontinued or interrupted due to development of adverse drug reactions in any of the patients. Therefore in this study the efficacy and safety of PIPC/TAZ as initial antimicrobial treatment for FN in patients with hematological malignancies were not inferior to those of 4th Cephs. Based on the preliminary data obtained in this study, we propose to conduct a multicenter, prospective, controlled study to compare PIPC/TAZ versus CFPM given as empirical antimicrobial treatment against FN in patients with hematological malignancies.展开更多
