Filter by:Prosthetic Joint Infection (PJI) is one of the severe complications following arthroplasty. With the global aging population, the number of patients undergoing primary joint replacement surgeries is increasing, leading to a rise in PJI cases. Although the incidence of PJI is generally low, the impact on patients can be catastrophic. Once an infection occurs, it is further complicated by the rising global antibiotic resistance, imposing a significant economic burden on patients. Therefore, improving the diagnostic rate of PJI is crucial. Currently, various infection markers are used in the diagnosis of PJI. However, there is still a lack of highly sensitive and specific markers to effectively diagnose PJI, necessitating the exploration of new infection markers. This study aims to investigate novel infection markers for the diagnosis of PJI, providing evidence for its diagnosis and subsequent treatment. In this research, we will prospectively collect data from patients undergoing primary joint replacement and those developing PJI from June 2024 to December 2026. These patients will be categorized into non-infection and infection groups. By collecting and analyzing general patient data, surgery-related information, and infection-related indicators from preoperative joint fluid and blood samples, we aim to further evaluate the predictive value of these infection markers for PJI.
This is a single-patient, phase I/II clinical trial that aims to evaluate the potential of a bacteriophage cocktail to treat and prevent the recurrence of a methicillin-susceptible Staphylococcus aureus prosthetic joint infection of the hip. The patient has exhausted all conventional therapies, both surgical and medical, at considerable detriment to his quality of life. The treatment involves a one time, intra-operative injection of bacteriophages into the joint and 14 days of intravenous phage therapy. The goal is to eliminate the infection and prevent further complications, providing a potential new treatment avenue for patients with difficult-to-treat infections.
The eradication of biofilms from infected implants is still an unsolved challenge. The high-energy light beam of an Er:YAG laser causes rapid heating and explosive ablation of tissue. In this study we test the suitability of this laser for the removal of biofilms from infected implant surfaces.
In the US, if you get an infection in your artificial knee joint that doesn't heal with antibiotics alone, the standard treatment is a two-stage revision of the artificial knee. In the first stage, your surgeon will remove your artificial knee and clean out the area around the knee. They will then place an antibiotic spacer. An antibiotic spacer is a type of artificial joint that will release antibiotics in to the knee space continuously over time. The spacer allows only very basic function of the knee. You may need to use crutches or a walker while the antibiotic spacer is in place. After surgery to place the antibiotic spacer, your surgeon may prescribe a course of antibiotics as well. Because the antibiotic spacer is not as durable as a regular artificial joint, after the infection is gone, another surgery is required to take the spacer out and put a new artificial knee joint in. There is another way for artificial joint infections to be treated. This is a one-stage revision. In this treatment, the surgeon will remove your artificial knee and clean out the area around the knee. Then they will place a new artificial knee in using a special kind of cement that contains antibiotics. The cement will release antibiotics in to the knee space continuously over time (your surgeon may prescribe a course of antibiotics as well). The new artificial joint with antibiotic cement will function almost the same as your original artificial knee. This means that while the infection is healing you will be able to do most of your regular daily activities. However, the antibiotic cement is not as durable as what is normally used to implant an artificial knee. The artificial knee with the antibiotic cement may need to be replaced with a regular artificial knee. When replacement will need to be done is dependent on your weight, bone strength and activity level, among other things. When it is time to replace the antibiotic cement artificial knee, you will have another surgery where the surgeon will take the antibiotic cement artificial knee and but a new artificial knee joint in. We know that both the one- and two-stage revision work equally well to heal the infection, but we don't know which patients prefer or which provides better function after many years. This study will randomly assign patients to receive either a one-stage or two-stage revision and then follow them for 5 years to ask them about pain, function, and satisfaction.
Background. Infection is the most common complication of complications after joint arthroplasty. During the COVID-19 pandemic increased used antibacterial drugs by adults, this could change the spectrum of infectious agents and their antimicrobial resistance. The purpose of the study is to evaluate the microbial diversity of pathogens of periprosthetic infection in the pre- and post-Covid period, determining the sensitivity of the leading pathogens to antibiotics. Materials and methods. A comprehensive comparative retrospective study was carried out on 342 cases of monomicrobial and polymicrobial periprosthetic infection (PPI) of limb joints with microbiological growth of microorganisms in the pre-Covid (2018-2019) and post-Covid (2021-2022) periods.
Purpose: C-reactive protein to albumin ratio (CAR) has emerged as a novel marker of inflammation. However, almost no research has evaluated the role of CAR in septic arthritis (SA). There is currently controversy over the timing of surgery. Our aim is to explore the application of the CAR in predicting the treatment choice for SA in children under 4 years of age. Methods: Retrospective analysis of the clinical data from children under four years of age admitted to the Department of Orthopedics at Children's Hospital of Soochow University between January 2016 and December 2022 due to SA. Patients were divided into surgery group and conservative group based on whether they underwent surgery. The clinical data of the two groups were compared. Multivariate logistic regression analysis was performed to determine the independent predictors for SA requiring surgical intervention. Receiver operating characteristic (ROC) curves were plotted for the independent predictive indicators, and the area under curve (AUC) was determined. The cut-off value was determined using Youden index, and diagnostic accuracy indicators such as sensitivity (SEN), specificity (SPE), positive predictive value (PPV) and negative predictive value (NPV) were calculated.
In this Dutch multicenter clinical trial, patients with a staphylococcal prosthetic joint infection, will, in the oral antibiotic treatment phase, be randomized between clindamycin monotherapy and rifampicin / levofloxacin combination therapy. The clinical endpoint will be treatment success one year after finishing antimicrobial treatment.
Bone and joint infections (BJI) with and without prosthetic material (knee, hip and shoulder) are complex to diagnose and treat, justifying the creation of expert centers by the French Ministry of Health (CRIOAc). In case of BJI with material, the diagnosis is based on a set of clinical, bacteriological, cytological and radiological criteria known as the EBJIS 2021 (European Bone & Joint Infections Society) criteria. For septic arthritis, diagnosis is based on bacteriology and cytology. Microbiology remains essential, and the delay of obtention of microbiological results is crucial to adapt the antibiotic treatment. Although, culture-based microbiology remains the most common diagnosis of BJI, its regular failure to identify the causative pathogen as well as its long-term modus operandi motivates the development of rapid and accurate molecular methods. The DendrisCHIP®OA platform has demonstrated its ability to offer routine molecular identification of the current micro-organisms involved in BJI, in less than 5 hours, with the detection of mecA resistance genes on series of 16 to 64 samples . The DendrisCHIP®OA is CE-marked and has already been the subject of an initial publication evaluating its performance in a single center. The main objective of this study is to evaluate the diagnostic performances of the DendrisCHIP®OA in detecting the pathogens recognized in its panel and the detection of the mecA gene compared with the routine microbiological techniques used in the inclusion centers participating to the study. The study aims to include 100 patients during 6 months in five inclusion centers in the Ile de France region.
The objectiveof this of a prospective, multicentre study is to evaluate the performance of shotgun metagenomics in the diagnosis of chronic Prosthetic joint infection (PJI) in comparison with the adapted MSIS diagnostic score.. The main questions it aims to answer are: - To evaluate the performance of shotgun metagenomics in the diagnosis of chronic PJI in comparison with culture. - To describe the epidemiology of bacterial species responsible for chronic PJI in Western France and their potential resistance to antibiotics. - Analyzing the diagnostic performance of shotgun culture and metagenomics as a function of potentially administered antibiotic treatments A total of 143 patients sampled will be included. Six intraoperative samples will be taken for each patient, as part of routine care. In addition to the standard preoperative check-up, an extra volume of blood will be taken for CRP measurement at inclusion.
Patients presenting with prosthetic joint infections of a total knee replacement who are treated with an antibiotic spacer will be observed prospectively for their response to treatment and antibiotic elution profiles will be measured post-operatively utilizing mass spectrometry from synovial fluid acquired as part of standard of care in the management of prosthetic joint infection. Secondary outcomes including post-operative complications, re-operation rates, and re-admission rates will also be compared.
