Filter by: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.
Open-label, multicentre, prospective cohort, observational clinical trial with a retrospective control group to evaluate the effectiveness and safety of CERAMENTTM| G or V used for filling of bone defects in the tibia and / or femur shaft and/or acetabulum in patients scheduled for two-stage hip or knee prosthesis re-implantation for PJI or aseptic loosening. The results will be compared to a cohort of patients, which have been treated before the introduction of CERAMENTTM|G or V for the same indication. Due to the observational character of the study, there will be no patient randomization and the clinicians in the study will remain entirely free to decide on the treatment of the patients according to established clinical practice. Only patients for whom therapeutic strategy for the use of the product for filling bone defects is already planned according to local clinical practice, at the time of informed consent form signature, will be enrolled in this study. Thus, the decision for the choice of the surgical treatment, will not be influenced by the inclusion of the patient in this study.
