Filter by:A prospective, open-label, randomized controlled trial will be conducted to evaluate a novel TDM-guided therapy in management of DT-GNB infections. We hypothesize that TDM-guided antibiotic therapy will reduce 14-day all-cause mortality by 6% (absolute risk reduction) in septic patients with DT-GNB infections, when compared to standard therapy. TDM for 11 antibiotics will be performed for all trial patients although test information will be withheld for the standard therapy arm. The primary aim is to compare the 14-day all-cause mortality rates of novel TDM-guided antibiotic dosing versus standard therapy.
Ocular rosacea is an inflammatory disease of the eyelids and ocular surface. Like the facial disease, the ocular condition is chronic and recurrent. Sequelae of ocular rosacea vary from mild to severe. Ocular rosacea may cause chronic eye redness, blepharitis, recurrent chalazia, dry eye, corneal erosion, corneal vascularization, and corneal ulceration. Rosacea affecting the cornea can result in vision loss. Prescription eye drops and ointments can be used topically to control mild ocular rosacea. However, severe disease, or rosacea that is not well controlled with local treatments is treated systemically. The most commonly used systemic treatment for rosacea is the bacteriostatic antibiotic doxycycline. Rosacea treatment doses of doxycycline vary widely. Treatment-dose doxycycline for systemic infections is 100mg twice a day. However, as rosacea is considered an inflammatory disease, doxycycline is often dosed at what is termed, sub-microbial dose doxycycline (SDD). Initially introduced in the oral medicine literature, SDD are doses 40mg and lower because systemic administration at this dose does not appear to alter the oral mucosa flora or increase resistance rates when given long-term for periodontal disease. Whereas 100mg doxycycline, even when given short term, may increase the percentage of culturable nasopharyngeal flora that is resistant to doxycycline. The FDA does not categorize SDD an antibiotic, stating this dosing is expected to exhibit only anti-inflammatory activity.
In Sub-Saharan Africa (SSA), fever remains a major public health problem in children. The introduction of malaria rapid diagnostic tests (RDTs) in routine healthcare has greatly improved the management of malaria. However, despite the good attitude of healthcare workers to adhere to malaria RDT test results, persisting hrp2antigen and low sensitivity of pLDH RDT negatively affect antimalarials and antibiotics prescriptions practices. This is one of the main causes of antimicrobial resistance (AMR) and inappropriate management of febrile diseases. To improve the diagnosis of febrile diseases and subsequent prescription of antimicrobials, it is hypothesized that the implementation of an algorithm including a two-step malaria RDT PfHRP2/pLDH supported by point-of-care tests (POCTs) for C-reactive protein, oximetry, and bacterial infection such as Group A Streptococcus, and Salmonella/Shigella, will significantly improve the management of febrile diseases and thereby tackling AMR. To assess the value of the proposed algorithm, an open-label randomized controlled trial with three arms, enrolling febrile children under 5 years is proposed. - In the control arm, febrile children will benefit from a complete clinical examination. Treatment will be done according to the national guideline. - In RDTs decisional algorithm (RDT-DA) arm (intervention), the complete clinical examination will be supported by two-step malaria RDT and bacterial infections RDTs. Prescription will be left to the discretion of the healthcare workers. - In e-algorithm arm (intervention), the complete clinical examination and the outcomes of RDTs (malaria and bacterial infections) will be digitalized. Diagnostic and prescription will be done by the algorithm. A final follow-up visit (day7) will be scheduled for all participants. Patients will be asked to return to the health facilities in case of no improvement. Primary study outcomes will be the proportion of curative case and antimicrobial(s) prescribed in each arm. Secondary outcomes include: (i) adherence of healthcare workers to the algorithm; (ii) adherence of parents/guardian to treatment; (iii) accuracy of the algorithm for the diagnostic of malaria. This project will serve as a path of policy change in the management of febrile diseases and AMR. By relying on existing RDTs available, the implementation of this algorithm will tackle AMR and provide better care. If successful, the project will equip the lead applicant to establish himself as an independent researcher with ability to further build his own research team. The project will also offer training opportunities to young scientists, and further strengthen already existing capacities of the home institute.
There are significant variations in antimicrobial consumption across Canadian Neonatal Intensive Care Units (NICUs). Inappropriate and overuse of antibiotics can result in antimicrobial resistance and adverse outcomes among vulnerable neonatal populations. There are limited data on broad-spectrum antimicrobial use, multi-drug resistant organisms (MDRO) prevalence, and effective NICU-specific antimicrobial stewardship strategies. The aim of this study is to develop and implement NICU-specific antimicrobial stewardship strategies at both national and individual unit levels to promote optimal antimicrobial use and decrease the incidence of MDROs.
The main objective of the project is to evaluate the efficiency and cost-effectiveness of different strategies aiming at optimizing antibiotic prescribing in hospitals. In the first section of the project, the project team intend to map the different antimicrobial stewardship programs in French hospital, by investigating a sample of 30 healthcare facilities, and determine the strategies to be evaluated by the model. The investigators will also evaluate physicians' adherence to the intervention to promote better use of antibiotics and explore potential barriers and facilitators to the implementation of effective strategies.
