Filter by:Babies and children have an increased risk of getting an infection with a bacteria in the bloodstream (sepsis). It is often difficult for the doctor to determine whether a child has an infection of the bloodstream, because the symptoms are often unclear and can also occur in children who are not sick. To determine whether there is an infection, a little blood is currently taken for a blood test (the blood culture) to investigate whether there is a bacteria in the blood. However, it often takes at least 36 hours before the results of this blood culture are available. That is why antibiotics are usually started immediately to treat the possible infection. However, it often turns out that the blood culture is negative after 36 hours, which means that no bacteria have been found in the blood. Usually the antibiotics are then stopped because it turns out that there was no infection at all. There is currently no good test that can predict whether (newborn) children have an infection or not. That is why too many children are currently wrongly receiving antibiotics. These antibiotics can damage the healthy bacteria in the intestines. There are many billions of 'beneficial bacteria' in the intestine. These play an important role in the digestion of food and protect against external infections. Antibiotics aim to kill bacteria that cause inflammation or infection. Unfortunately, antibiotics also kill some of these beneficial bacteria. In addition, unnecessary use of antibiotics contributes to antibiotic resistance. The aim of this research is to investigate whether Molecular Culture, a PCR based test that can identify bacterial pathogens in bodily fluids within 4 hours, has greater accuracy than traditional culturing techniques for bacteria in blood. If proven, this could lead to faster identification or exclusion of sepsis in children.
The Virtual Antimicrobial stewardship Team (VAT) study aims to evaluate, in a randomized controlled trial (RCT), the effect of a weekly virtual antimicrobial stewardship (AMS) intervention on the appropriateness of prescribing antibiotics for nursing home (NH) residents with urinary tract infections (UTI), respiratory tract infections (RTI) or skin and soft tissue infections (SSTI) compared to standard care for NH residents in Dutch NHs in the provinces of North-Holland and Flevoland. The secondary aim is to identify barriers and facilitators to implement a stewardship intervention and subsequently develop an implementation guide.
Severe infections can be caused by various organisms, such as bacteria or viruses, and lead to otherwise healthy people getting very unwell, sometimes needing treatment in hospital or even intensive care. For the treatment of bacterial infections to be successful, the correct antibiotics need to be given promptly. Early in the course of illness, clinicians often do not know exactly which bacteria are causing the infection. Furthermore, patients differ in terms of how their bodies process the antibiotics they are given; this means that some may get too much and others too little. This can in turn lead to some patients not being fully cured, and others coming to harm due to side effects of higher doses of these drugs. For certain types of antibiotics, clinicians are able to measure their levels in the bloodstream, which can help guide dosing. This is called therapeutic drug monitoring, and is commonly used in clinical practice. One of the problems with therapeutic drug monitoring is that it is often not available outside of regular working hours, is costly, and most importantly, provides clinicians with useful information only after a few days of treatment have already been completed. This may be too late to treat these severely ill patients with life-threatening infections, where early and appropriate treatments matter. The aim of our study, called TDM-TIME, is to look at how long it takes for blood samples to get from the patient to the laboratory to be measured, with the results then communicated back to clinicians. We are further looking to investigate whether steps can be taken to improve these timings, which would lead to shorter times until treatments can be improved. As our study is observational, we will not change anything about the treatment of our patients, but will only be measuring levels of antibiotics in their blood.
The goal of this prospective study is to compare rapid molecular technique BioFire Pneumonia Panel Filmarray and conventional culture-based methods in the microbiologic diagnosis on bronchoalveolar lavage of lung transplant patients. The main questions it aims to answer are: - determine the microbiological concordance between molecular diagnostic and conventional culture techniques on donor's bronchoalveolar lavage before lung transplantation - determine the microbiological concordance between molecular diagnostic and conventional culture techniques on recipient's bronchoalveolar lavage, performed 72 hours after lung transplantation - determine the microbiological concordance between molecular diagnostic and conventional culture techniques in detecting molecular resistance patterns - determine the difference in time to microbiological results between molecular diagnostic and conventional culture techniques - determine time to clinical decision based on molecular diagnostic techniques compared to conventional culture techniques
The investigators designed an observational multicenter explorative in vivo study to investigate the changes in ceftriaxone pharmacokinetics in blood and ascites. The investigators will include a total of 20 patients with liver cirrhosis admitted to the ward of participating hospitals. Patients are eligible when receiving ceftriaxone and concomitantly receive paracentesis. The investigators will collect all available waste blood samples of each participant, starting from study entry up until 48 hours after the last dosing interval of ceftriaxone. The investigators will collect all available waste ascites samples of each participant up until 48 hours after the last dosing interval of ceftriaxone. Duration of the trial: The study duration is variable and depends on the duration of ceftriaxone treatment and duration of hospital admission, which both are determined by the treating physician and is not influenced by study participation. Patients will be eligible for study inclusion when patients received (a single dose of) ceftriaxone treatment and undergo paracentesis during ceftriaxone treatment. The study will end 48 hours after the last dosing interval of ceftriaxone or until hospital discharge, whichever comes first. Study timeline: The investigators expect to enrol 1-2 participants every month. The total enrolment time will thus be approximately 12 months.
Getting the right dose of antibiotic promptly is an important part of treating infections. Unfortunately, when an infection is severe (sepsis) the body changes how it processes antibiotics. Consequently, some people with severe infection retain antibiotics for too long (risking adverse effects), whilst others excrete antibiotics too quickly (risking under-treatment). Mathematical models can help researchers understand drug handling variability (known as pharmacokinetics) between people. These models require very accurate information about drug administration and drug blood concentration timings. Researchers usually rely on someone recording these timings, but recording errors can make models inaccurate. We would like to understand if using data from routinely used electronic drug infusion devices (recording the exact time of administration) can improve the accuracy of pharmacokinetic models. We intend to investigate this with an antibiotic (vancomycin) that clinicians already routinely monitor blood concentrations for. Adults and children treated at St George's Hospital intensive care units will be invited to participate in the study which will last for 28-days within a 14-month period. Participants will donate a small amount of extra blood and provide researchers access to their clinical data. Blood will be taken at special times during vancomycin treatment from lines placed as part of standard treatment, minimising any pain or distress. There will be no other changes to patient's treatment. In the future, data from this study might help change the way we dose antibiotics. The National Institute for Health and Care Research and Pharmacy Research UK are supporting the study with funding.
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.
Specific Aim : The specific aim is to conduct a randomized prospective clinical trial to determine whether no antibiotics in OHCA patients in the ED with very low likelihood of infection is non-inferior to early antibiotic treatment. Hypothesis a: 28-day all-cause mortality will be non-inferior in OHCA patients with very low likelihood of infection who do not receive antibiotic therapy compared with those who receive early antibiotic therapy Hypothesis b: There will be no difference in subsequent incidence of proven infections in the no antibiotics vs, early antibiotics groups Hypothesis c: There will be no difference in the length of ICU stay and overall hospital stay in the early antibiotics vs. no antibiotics groups
Value of TDM for teicoplanin is not well defined. In this single-center low-interventional randomized trial the investigators aim to investigate the superiority of teicoplanin TDM-optimized using Model-Informed-Precision-Dosing (MIPD) of unbound concentrations versus the standard of care (dosing based on antibiotic guidelines) in target attainment.
External ventricular drain infections are difficult to identify with current diagnostic methods. Initiation of antibiotic treatment is usually supported by indirect methods of bacterial infection, such as clinical signs or cerebrospinal fluid cell counts (CSF). As such, excessive treatment with antibiotics is common in these patients due to suspected infection while the incidence of true culture confirmed infections are less common. This study will evaluate three novel diagnostic methods for rapid direct bacterial detection in CSF, in order to assess if these can be used to guide antibiotic treatment in neurocritically ill patients, compared to CSF bacterial cultures.
