Filter by:This study aims to validate a novel antibiotic susceptibility test (InSignia) for gonorrhoea in patient clinical samples. The hypothesis is that the InSignia test will be able to detect transcriptional responses after incubation in antibiotic for susceptible strains and not resistant strains. Furthermore, this study will also add to our understanding on the performance of this test in various clinical specimens.
This is an experimental study without drug and device, non-profit, on biological samples stored at the Tropica Biobank of the DITM. The aim of the project is to verify the performance of NGS-based assays, which can be used in the field of microbiology. The clinical evaluation investigations of NGS technology will be conducted on an adequate number of clinical blood samples and rectal swabs. The analyzes will be compared with the standard microbiology methods used in the DITM diagnostic routine.
The misuse, irrational, or overuse of antibiotics, antibiotic/antimicrobial resistance (AMR) is a global threat to human health. Even though the awareness of the potential threat from AMR is widespread, studies and monitoring programs describing the present situation are lacking. The presence of a 'pluralistic' health system and a large informal sector involving unqualified drug dispenser/providers/practitioners in Bangladesh is a matter of grave concern for the rising antimicrobial resistance situation in the country. An estimated 63% of antibiotic prescriptions are from unqualified providers. Besides, misconception about antibiotics is very common in Bangladesh. Meanwhile, the use of antibiotics in animal food production with insufficient veterinary supervision for therapeutic purposes which poses the risk of antimicrobial resistance transmission in the food chain. Without adherence to national regulations, unnecessary and inappropriate prescriptions become common practice, particularly in rural areas. Domestic drug industries contribute to easily accessible and affordable drugs. To tackle this problem, prescriptions and sales of antibiotics need to be regulated and integrated in a national HMIS. Awareness programs for antibiotic providers that promote understanding of antibiotics and antibiotic resistance through tailored interventions may be helpful in changing current antibiotic sales practices. Therefore, this study will attempt to identify the underlying causes of irrational anti-microbial usage in Bangladesh, which were grouped into four interlinked areas - lack of awareness among patients/ consumers (demand side), perverse incentives and lack of knowledge among providers (supply side), poorly regulated pharmaceutical marketing and retail sales (regulatory side) and lack of data and research evidence to support awareness raising and policymaking (enabler). A before-after designed quasi experimental study will be conducted in urban areas. Data will be collected in both qualitative and quantitative methods. Multi-cluster sampling method will be used to select study locations. Pharmacists or drug sellers and patients aged more than 18 years and located within selected intervention areas will be our target population. A baseline survey will be conducted among the pharmacy volunteers to evaluate their knowledge, perception, and practice of rational use of anti-microbials prior to any intervention. Additionally, a household survey will be conducted among community members applying systematic random sampling where one adult from every selected household will be approached maintaining gender equality. After collecting the baseline data, intervention will be given to the community people through awareness building campaign and distributing leaflets and posters on rational use of anti-microbials. After three months, a follow-up survey will be conducted among the same participants with the same questionnaire. For quantitative portion of the study, all the medicine shops in the selected study areas will be included in the study sample alongside a total of anticipated 6240 community dwellers. For qualitative part, the sample will be selected purposively until data saturation and a total of 20 experts will be interviewed. Two sets of questionnaires for pharmacy volunteers and the community dwellers will be prepared based on literature review that will include health literacy questions regarding anti-microbial use. The questionnaire for the follow-up data collection will include some additional questions regarding acceptability, adoption, feasibility, and cost of the intervention. The study is expected to bring light upon a comprehensive understanding of the current level of knowledge, perception and practice of irrational use of anti-microbials among target population. Furthermore, a digital intervention design will be produced to reduce irrational use of anti-microbials after considering its effectiveness. The wide range of the study findings will aid in assessing the acceptability, adoption, feasibility and cost of the intervention to make recommendations on sustainability and scaling up of the intervention programs.
The MORDOR trial found that biannual distribution of azithromycin to children 1-59 months old reduced child mortality. The World Health Organization (WHO) released conditional guidelines for this intervention, which include targeting azithromycin distributions to children 1-11 months of age in high mortality settings. The proposed trial aims to demonstrate and evaluate large-scale implementation of azithromycin to children aged 1-11 months old in the context of a programmatic setting while monitoring mortality and resistance antimicrobial resistance.
The purpose of this study is to evaluate the safety and effectiveness of the T2Resistance Panel by validating clinical performance in three study arms: 1. Prospective arm: positive percent agreement (PPA) and negative percent agreement (NPA) against genetic determinants of resistance detected in whole blood clinical samples or isolates collected from positive blood cultures prospectively collected clinical samples of whole blood. 2. Contrived arm: positive percent agreement (PPA) and negative percent agreement (NPA) against samples with known status, via spiking healthy whole blood samples with bacterial strains harboring the resistance gene targets on the T2Resistance Panel. 3. Healthy donor arm: negative percent agreement (NPA) with presumed negativity of healthy donor whole blood samples. The data from all arms of the study will be used to support the Premarket Notification for the T2Resistance Panel to the U.S. Food and Drug Administration. Primary Endpoints The primary endpoints of this study with the T2Resistance Panel are estimated sensitivity, specificity, and safety.
The aim of this study is to determine the effectiveness of rifabutin triple therapy for the treatment of H. pylori infection in the Israeli population. Patients with or without a prior history of H. pylori eradication failure will be randomized to receive one of three possible treatments: Group 1-amoxicillin 1000mg bd and rifabutin 150 mg bd and esomeprazole 40 mg bd Group 2- amoxicillin 1000mg bd and rifabutin 150 mg d and esomeprazole 40 mg bd Group 3- standard of care
The Cepheid Xpert MTB/XDR cartridge, which runs on the same platform as Xpert MTB/RIF Ultra, has been developed to detect additional resistance to isoniazid, fluoroquinolones and second-line injectable anti-tuberculosis drugs and provides results within 2 hours and on primary samples. An evaluation of the the Xpert MTB/XDR assay is currently underway in clinical settings in South Africa, India and Moldova. The TB-CAPT MTB/XDR Study will add further diagnostic accuracy and feasibility data to the evidence base for the Xpert MTB/XDR assay.
The MORDOR trial found that biannual distribution of azithromycin to children 1-59 months old reduced child mortality. The World Health Organization (WHO) released conditional guidelines for this intervention, which include targeting azithromycin distributions to children 1-11 months of age in high mortality settings.Targeting treatment to children 1-11 months old could reduce antimicrobial resistance by limiting antibiotic distributions while treating children at the highest mortality risk. However, this targeted intervention has not yet been tested. The AVENIR mortality/resistance trial aims to assess the efficacy of age-based targeting of biannual azithromycin distribution on mortality as well as determine the impact of age-based targeting on antimicrobial resistance.
Colonization by Multiple Drug Resistant Organisms (MDROs) during patient hospitalization requires expensive isolation measures and renders the return or transfer to other departments or institutions often impossible. Currently there is no specific treatment available. Patients have to wait for spontaneous clearance which can take months or does not happen at all. The study will test the effect of Fecal Microbiota Transfer (FMT) on gut MDRO colonization. The focus will be on patients with a long-term colonization by Gram-negative bacteria for which isolation is warranted. Participants will be randomized into two treatment groups; allogenic FMT versus autologous FMT. A third group of participants will be monitored but will not receive an FMT. Decolonization rate will be compared one month after treatment. Additionally gut microbial composition will be studied up to one year after FMT.
Eurobact II will investigate the mortality and morbidity of hospital-acquired blood stream infections in patients treated in intensive care units (ICU). It will investigate the effects of the micro-organism and its characteristics, such as type and resistance to antibiotics on the infection and its consequences. It will also investigate the effects of the antibiotics and other treatments on survival of patients. Eurobact II will include patients from multiple ICUs in multiple countries.
