Bone and joint infections (BJI), although infrequent (prevalence of 70 per 100,000 in France), have a significant economic and clinical impact. Between 2008 and 2013, the prevalence of BJI increased and infections involving joint prosthesis (PJI) represent a third of BJI in France. They are most often post-operative and more expensive than native IOAs. This study aims to describe PJI and understand the failure mechanisms of PJI in order to improve their management.
One of the major causes of prosthetic joint failure is infection. Recently, coagulase-negative Staphylococci (CoNS) have been identified as emergent, nosocomial pathogens involved in subclinical prosthetic joint infections (PJIs). The diagnosis of PJIs mediated by CoNS is complex and demanding due to the absence of clear clinical signs derived from the host immune system response. In this scenario, the key to successful surgical treatment is the capability to differentiate between aseptic implant loosening and septic failure. Hence, the central hypothesis of this study is that proteomic analysis of the secretome of CoNS clinical isolates associated with the characterization of patient synovial fluids will reveal a panel of putative biomarkers tightly linked to PJIs. The confirmation of the presence of bacterial PJI biomarkers in synovial fluids of infected patients will pave the way for the development of a new reliable test capable of aiding in the diagnosis of subclinical PJIs.
This is a multi- centre trial of children with bone and joint infections (BJIs) at eight major paediatric hospitals in Australia and New Zealand. The primary objective is to establish if in children with acute, uncomplicated BJIs, entirely oral antibiotic treatment is not inferior to initial intravenous (IV) treatment for 1 to 7 days followed by an oral antibiotic course in achieving full recovery 3 months after presentation. Children will be randomly allocated to the 'entirely oral antibiotic' group or the 'standard treatment' group.
Ofloxacin is a gold standard antibiotic for the treatment of bone and joint infections due to sensible staphylococcus strains. However, in the elderly, inter-individual variability of the pharmacokinetics may reduce the efficacy or increase toxicity. The occurrence of ofloxacin side effects is likely to be increased in case of higher exposition. However, the serum concentration-toxicity relationship has not yet been determined. The purpose of this project is to assess the association between the residual serum concentration of ofloxacin at day 3 and the occurrence of at least one adverse effect attributable to ofloxacin, and determine a threshold toxicity concentration if this association exists.
The overall purpose of this clinical treatment research project is to explore novel diagnostics that can guide the treatment of infections associated to orthopaedic implants, in order to improve patient outcomes and reduce the development of antibiotic resistance. The project aims are: (i) To improve the current diagnostic approaches and treatments of periprosthetic joint infections (PJI) (ii) To investigate the pathogenesis of PJI through the characterization of the virulence carried by the causative pathogens This multidisciplinary project addresses implant-associated infection and its contribution to increasing antibiotic resistance. Both lead to longer hospital stays, higher medical costs and increased morbidity and mortality. Antibiotic resistance is globally considered as one of the greatest and most urgent risk in medicine. Implant-associated infections are commonly caused by biofilms. Biofilms can be described as 'a community of bacterial cells connected by their secreted extracellular matrix'. Since antibiotics are designed to fight planktonic free-living bacteria, studying antibiotic resistance in biofilm communities poses a paradigm shift. Furthermore, bacteria in biofilms are up to 1000 times more resistant to antibiotics than planktonic bacteria. Mechanisms involved in a biofilm infection also play a crucial role in the development of antibiotic resistance. Hospital-acquired infections are the fourth leading cause of disease and 70% are associated with medical implants and caused by staphylococcal biofilms. In addition, the level of antimicrobial resistance in bacteria causing implant-associated infections has increased worldwide, leaving patients with fewer treatment options. In this study the investigators will randomize patients with PJI to either standard MIC susceptibility or MIC and MBEC susceptibility guided treatment with oral antibiotic combinations; (i) Non cell wall active standard of care antibiotic combination (MIC-guided) for 6 weeks. (ii) Or; non cell wall active antibiotic combination according to a MBEC-based decision algorithm for 6 weeks. In this pilot project, the primary endpoint is how often treatment changes with the MBEC susceptibility testing compared to only MIC-susceptibility testing.
It is not known in the literature how much sonication affects the patient's treatment. Another important issue is that the place of this method in diagnosis is not clear. The aim of this study is to contribute to the literature on this issue and to determine the sensitivity and specificity of sonication prospectively using the new definition and effect of sonication on the treatment strategy in terms of infection in patients with PJI.
Lactate levels are rapidly available and may potentially aid in diagnosing septic arthritis in a native joint. This study will determine the utility of synovial lactate in discriminating septic from aseptic arthritis.
Patients who are admitted to hospital with serious infections, such as those in bone, joints or spine, require a long course of intravenous (IV) antibiotics. After an initial treatment course in hospital or through a dedicated outpatient antibiotic program many patients can complete their treatment course at home. Such infections are often caused by bacteria called Staphylococci, and currently there are three antibiotic options used routinely. A fourth antibiotic, ceftriaxone, is a promising alternative; it is also effective against Staphylococci, and is more convenient, less costly and easier to give at home, however, it has not been studied thoroughly in a prospective manner. This study will compare ceftriaxone to routinely used antibiotics (cloxacillin, cefazolin or daptomycin) to see if ceftriaxone is equally as safe and efficacious in curing deep-seated Staphylococcal infections in patients receiving home IV antibiotics. Patients with deep-seated infections caused by methicillin-susceptible Staphylococcus aureus (MSSA) or coagulase-negative Staphylococcal species will be randomly assigned home IV treatment with ceftriaxone OR one of the three other antibiotics before leaving the hospital. Patients will then receive usual care from an Infectious Disease physician and Home IV team. The study team will assess whether cure has been achieved by the end of the IV treatment, follow-up at 6 months to see if patients remain infection-free, and record any side-effects of treatment. The overall goal is to determine whether ceftriaxone can be considered non-inferior to usual antibiotic treatment in treating Staphylococcal infections in a home IV setting.
The number of arthroplasties is expected to grow in the next few years. Staphylococcus aureus (SA) is a primary cause of prosthetic joint infection (PJI) with serious consequences. This microorganism is frequently associated with treatment failure, hospitalizations and need of prosthesis removal, leading to an important morbidity and an increase in healthcare costs. ARTHR-IS is a retrospective multi-center study which aims to estimate the burden of SA-PJI after a hip or knee arthroplasty and their risk factors. Other objectives are to quantify the costs, the number of hospitalizations and the surgical procedures needed to treat and control the infection and finally the factors influencing therapeutic failure. Through a case-control design, ARTHR-IS will group 20 hospitals across 5 European countries in order to include 150 cases and 450 controls. The results of this study will provide critical information to develop strategies to prevent and treat SA-PJI and reduce treatment failures. Also, the results from ARTH-IS study will help in the design of future clinical trials in prosthesis infections by providing reliable estimates on the incidence of SA-PJI and the subsequent burden on health care services.
