This prospective study aimed to evaluate the eradication efficacy of high-dose dual therapy (HDDT) with esomeprazole and amoxicillin in a region with high resistance rates to clarithromycin, metronidazole, and levofloxacin.Methodology: A total of 82 patients with active H. pylori infection, confirmed by either a rapid urease test or a ¹³C urea breath test, were enrolled at our hospital. All participants received esomeprazole (40 mg) and amoxicillin (1,000 mg), 3 times daily for 14 days. Treatment success was assessed using a ¹³C urea breath test 4-6 weeks post-treatment. Safety was evaluated based on reported adverse effects.Results: Gastritis, gastric ulcer, and duodenal ulcer were present in 80.5%, 10.4%, and 9.1% of cases, respectively. The eradication rates according to intention-to-treat (ITT) and per-protocol (PP) analyses were 76.8% (63/82) and 81.8% (63/77), respectively. In the PP analysis, the eradication rate was 86.0% (49/57) in first-line treatment, and 70.0% (14/20) in patients with prior H. pylori treatment failure. Mild side effects, including nausea, abdominal discomfort, pruritus, diarrhea, and fatigue, were reported in 22.1% (17/77) of patients.Conclusions: This study demonstrates that a 14-day HDDT regimen provides relatively high efficacy and a favorable safety profile for first-line H. pylori eradication. Given the widespread resistance to clarithromycin, levofloxacin, and metronidazole in Vietnam; HDDT may serve as an alternative first-line therapy for H. pylori eradication in this region.","PeriodicalId":49160,"journal":{"name":"Journal of Infection in Developing Countries","volume":"19 3","pages":"404-408"},"PeriodicalIF":1.4,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143765710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the safety of quinolone use in pediatric patients remains inadequately established, with limited recommended applications. This study aimed to investigate the escalating consumption of quinolones among Brazilian children aged 0-10 years.Methodology: An interrupted time series analysis was conducted to examine fluctuations in quinolone consumption within the pediatric population. Data were sourced from the Brazilian National Controlled Products Management System (SNGPC). Analysis of variance and joinpoint regression were employed to assess yearly variations in commercial unit sales of quinolones.Results: Brazil witnessed the consumption of approximately 93 million commercial units of quinolones by the entire population, with 1 million units prescribed for children (0-10years). The surge in quinolone utilization among children during this period exceeded 50% (p < 0.05), a statistically significant increase compared to the 24% growth observed in the entire population. Regression analysis indicated an annual linear growth of around 9% (year on year) in Brazil for quinolone use among children.Conclusions: Our study revealed a concerning rise in quinolone prescriptions for Brazilian children aged 0-10 years, underscoring the imperative for cautious use due to limited safety data and acknowledged risks, such as musculoskeletal damage. Healthcare providers should prioritize safer alternatives when possible, focusing on children`s well-being and combating antimicrobial resistance. Advocacy for prudent prescribing practices and increased awareness is crucial, along with further research to comprehensively understand long-term effects and establish evidence-based guidelines for quinolone use in pediatric populations.","PeriodicalId":49160,"journal":{"name":"Journal of Infection in Developing Countries","volume":"19 3","pages":"418-423"},"PeriodicalIF":1.4,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143764396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There have been reports of colistin-resistant (Col-R) and heteroresistant (hR) MDR and XDR-GNB strains worldwide. Therefore, we aimed to ascertain the rate of colistin resistance, certain potential resistance mechanisms, and heteroresistance in colistin-susceptible (Col-S) clinical isolates.Methodology: Identification and Antibiotic susceptibility test (AST) for all isolates were determined by Vitek-2 automated system. The Col-S strains were evaluated for heteroresistance using the population analysis profiling (PAP) method, while the Col-R strains were tested for mcr-1 gene activity by combined disk test (CDT) and colistin minimum inhibitory concentration reduction (CMR) test. The efflux pump mechanism was identified using cyanide 3-chlorophenylhydrazone (CCCP).Results: Out of 60 isolates enrolled in the study, AST revealed that 60% were MDR-GNB and 40% were XDR-GNB. Ten isolates were colistin resistant (16.6%). The mcr-1 gene was detected in five (5/10) Col-R isolates by PCR. CDT test detected mcr-1 gene activity in four (4/5) of mcr-1 gene positive isolates, while CMR test detected all. Efflux pump inhibition by CCCP showed a reduction of MICs by ≥ 8-folds in four Coli-R isolates. The frequency of carbapenem resistance (CR) within Col-hR strains was 75%, while ESBL was 25%.Conclusions: The alarmingly high occurrence of colistin resistance and heteroresistance in hospital care settings is of major concern and necessitates a reassessment of recommended AST methods since it can result in colistin therapy failure.","PeriodicalId":49160,"journal":{"name":"Journal of Infection in Developing Countries","volume":"19 3","pages":"431-438"},"PeriodicalIF":1.4,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143765542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to examine patterns of infections and associated antibiotic use in children attending Primary Health Centers (PHCs), including an explanatory analysis of antibiotics for non-pneumonia acute respiratory infections (ARIs), pneumonia, and diarrhea.Methodology: An observational study used records of all children  5 years of age prescribed antibiotics from January 2019 to December 2020 in selected PHCs in Surabaya and Banjarmasin, Indonesia. Data on children's characteristics, diagnoses, and antibiotics prescribed, were collected from patient records. The explanatory analysis was based on national guidelines. A descriptive analysis was used to summarize the data.Results: A total of 1053 and 1463 children's records with antibiotics were located at Surabaya and Banjarmasin PHCs, respectively. ARIs were the most common indications for antibiotic prescribing in both settings, either non-pneumonia ARIs (60.6% versus 33.8%, respectively) or pneumonia (20.2% versus 25.2%, respectively). High conformity with guidelines were evident for antibiotics used for pneumonia (i.e., amoxicillin/cotrimoxazole/erythromycin - 89.3%) or specified upper ARIs (e.g., amoxicillin for pharyngitis - 73.9%), and for diarrhea (i.e., cotrimoxazole - 73.1%).
