Filter by:This study is a human challenge study to assess the feasibility and safety of controlled human malaria infection (via P. vivax sporozites) in healthy volunteers, and to develop a bank of P. vivax-infected blood for use in future controlled human P. vivax malaria infection studies. Additional objectives are to obtain data on host immune response to P. vivax infection and pre-treatment gametocytaemia. This study is funded by the UK Wellcome Trust. The grant reference number are Oxford/MORU: 212336/Z/18/Z and 212336/Z/18/A, and Mahidol University: 212336/A/18/Z and 212336/A/18/A.
The current study is a pilot study to assess the feasibility of a superordinate project. The final objective of this superordinate project is to describe and model the pharmacokinetic behaviour of a small number of standard antimicrobials used in the treatment of frequent blood stream infections, and to link this via pharmacodynamic models to (inhibition of) bacterial or fungal growth as well as to clinical outcomes in patients.
Diabetic foot problems, especially infections (DFI), require multiple resources including iterative surgeries and amputations, long-lasting antibiotic therapies, education, off-loading and eventually revascularization and appropriate foot-ware. Treatment is complicated, multidisciplinary, and marked with a high risk of recurrences. This is a retrospective and prospective cohort with side studies of pathologies and academic research questions that cannot be separated from each other. The investigators establish a retro-and prospective cohort of diabetic foot problems (ambulatory and hospitalized patients) and perform side studies to reduce the incidence of complications, and to reduce recurrences of DFI, cost and adverse events related to therapies. Cohort: Prospective and retrospective cohort of all diabetic foot problems with emphasis on surgical and infectious variables. Trial 1 (Randomized trial on residual infection after amputation): Determination of the level of amputation per MRI followed by a randomization concerning the duration of post-amputation systemic antibiotic therapy, if there is residual bone infection. Trial 2 (Randomized trial on infection without amputation): Determination of the duration of systemic antibiotic therapy in diabetic foot infections without Amputation of the infection.
Valacyclovir has replaced acyclovir in many clinical scenarios. Pharmacokinetic data support the use of oral valacyclovir in children, but practical problems exist in children having to take adult-dose tablets. A formulation with acceptable palatability, good pharmaceutical quality and possibility of flexible dosing is developed. Pharmacokinetic data of this formulation is missing. The present study investigates the pharmacokinetics of valacyclovir oral solution in children by determine the area under the curve (AUC0-12), time above critical concentration (Ccrit), Cmax and Tmax of acyclovir. Secondary, the safety profile of a single dose of valacyclovir oral solution will be determined.
242 patients (121 patients in each of the two treatment arms) will be included with a confirmed diagnosis of HIV-1 infection and with a stable antiretroviral treatment during more than 48 weeks with dual therapy (DTG + 3TC)
The aim of this study is to see if multiplex strip PCR will detect the pathogen that causing eye infection from the corneal scraping samples with higher sensitivity and specificity than the current gold standard.
The main hypothesis of the study is that Bezlotoxumab is well tolerated and effective in reducing the recurrence of ICD (Clostridium Difficile infection) in patients with a high risk of recurrence in the first episode of ICD. As a consequence, the number of readmissions and hospital stays, will be reduced in patients treated with Bezlotoxumab.
Septicaemia is a potential complication of nasogastric (NG) tube feeding contamination (Leanne, 2014; Anderton, 2000) and a major cause of morbidity and mortality in residential care home for elders ( RCHEs) (Leanne, 2014). Although health workers (HWs) and personal care workers (PCWs) are responsible for NG tube feeding and direct care to the residents who are fed by NG tube feeding under supervision of registered nurses (RNs) and enrolled nurses (ENs) in RCHEs, HWs and PCWs unfortunately receive limited training regarding infection control (Ho et al., 2012; NICE, 2012; Duckro et al., 2009; Bankhead et al., 2009). A multimodal ICP could reduce the incidence of NG tube feeding contamination by improving the knowledge and skills of RCHE staff members regarding NG tube feeding (Ho et al., 2012). However, because the intervention described by Ho et al. (2012) was not administered in a randomised manner, potential confounders that could affect the outcomes of interest were not adjusted. To overcome that limitation, the proposed work will establish a well-designed multimodal ICP and explore the effectiveness of this intervention in terms of enhancing the knowledge and skills regarding NG tube feeding of RCHE staff members and consequently reducing NG tube feeding contamination after adjusting for potentially important baseline factors. The proposed research objectives are as follows: 1. To explore the effectiveness of a multimodal ICP for reducing bacterial contamination, as measured by the total bacterial counts on NG tube hubs and fingertips on both hands of RCHEs staff, as well as in enteral milk; and 2. To investigate the effectiveness of a multimodal ICP for improving the knowledge and skills of RCHEs staff members regarding infection control measures during NG tube feeding in RCHEs setting.
Prospective, multicenter, observational study on the evaluation of efficacy of appropriate monotherapy vs combination treatment for non-complicated Enterococcus faecalis bloodstream infection (EF-BSI). The aims of our study are: Primary: To compare the efficacy of appropriate monotherapy vs combination treatment for EF-BSI, according to standard of care. Secondary: 1. To compare the impact on clinical outcome of the initial combination therapy in the subgroup of patients with enterococcal endocarditis. In this case we will evaluate only the antibiotic treatment administered before the diagnosis of endocarditis assuming that any case of endocarditis will be treated with a combination therapy. 2. To compare the efficacy of combination treatment (vs monotherapy) in the following subgroup of patients: A. Patients with low versus high risk of endocarditis according with the "Number of positive blood cultures, Origin of the bacteremia, previous Valve disease, Auscultation of heart murmur (NOVA) score". B. Patients with metastatic septic localizations. C. Patients with catheter-related BSI. D. Patients with indwelling cardiovascular device or prosthetic valve. 3. To validate the NOVA score as a predictor of enterococcal endocarditis in a large multicentre cohort of patients with EF-BSI. 4. To estimate optimal duration of treatment of EF-BSI in patients without endocarditis. 5. To evaluate the rate of 90-day development of Clostridium difficile infection. The promoting center is S. Orsola-Malpighi Hospital is a 1,420-bed tertiary care University Hospital in Bologna with an average of 72,000 admissions per year. A dedicate team of Infectious Diseases (ID) specialists is active in the promoting center. Investigators of this team have already coordinated multicenter studies on infections topics. Centers from other countries will be invited to participate by email, they will be ask to fulfil an agreement form. All consecutive, unselected patients with monomicrobial EF-BSI will be screened for study inclusion. We expect to enroll about 500 patients. Period of data collection will be from september 2019 to 31th December 2020.
This is a single center collection of discarded biological samples and electronic medical review (EMR) data on patients who are hospitalized with clostridium difficile infections and treated with Fidaxomicin
