Active clinical trials for "Arthritis, Infectious"

On joint orthopaedic hardware infections are one of the most frequently encountered complications in orthopaedic surgery. However 6% of the cultures remain sterile, etiological diagnosis cannot be established despite obvious signs of infection. As part of this research project, we have developed a new strategy diagnosis including directly the use of PCR to reduce the number of negative results. This should have a major therapeutic impact in terms of timeliness and specificity of antibiotic. Primary: Evaluate the effectiveness of the new diagnostic strategy on etiological identification of prosthesis infections. Hypothesis: Minimum 6 percent increase in the number of patients with an etiological diagnosis of infection on prosthesis.

Gut dysbiosis is an intestinal disorder that is characterized by accumulation of microbiota imbalance, host-microbiota crosstalk dysfunction and inflammation. As part of its clinical development, MaaT (Microbiota as a Therapy) Pharma is particularly interested in patients with Bone and Joint Infections (BJI). These patients are treated with antibiotics having significant consequences on their intestinal flora, causing intestinal discomfort, which can be manifested by diarrhea. MaaT Pharma wishes to carry out a clinical study, OSIRIS, in collaboration with Prof. Tristan Ferry, member and coordinator of CRIOAc (Centre de Référence des Infections Ostéo-Articulaires Complexes) Lyon, Center of Reference of Bone and Joint Infections (BJI). The objective of this study is to follow patients with treated BJI in order to characterize intestinal dysbiosis and the future relevance of an autologous Fecal Microbiota Transplantation (aFMT) intervention. To do this, patients will be monitored according to the current CRIOAc recommendations, with the aim of taking biological samples from patients at the same time as scheduled visits, routine monitoring patients. Only one additional consultation will be carried out 15 days after stopping the antibiotics in order to better evaluate the dysbiosis evolution. Thus biological samples (blood, stool, nasal, rectal) will be taken during the follow-up consultations over a period of 6 months.

This is a study to evaluate the efficacy of Ceftaroline in the treatment of bone and joint infections.

For more than fifty years, vancomycin has been cited as a nephrotoxic agent. Reports of vancomycin induced kidney injury (a.k.a vancomycin induced nephrotoxicity or VIN), have waxed and waned throughout the years for various reasons. Recently, VIN has reemerged as a clinical concern. This may be due to various reasons, including new dosing recommendations as well as an increased prevalence of risk factors associated with vancomycin induced nephrotoxicity. This study aims to evaluate a strategy which attempts to reduce kidney damage from vancomycin use.

To establish a new protocol in order to increase ultrasound diagnostic accuracy of pediatrics presented with signs of septic hip .

Testing and comparison of a novel point-of-care electrochemical assay to detect and help diagnose periprosthetic joint infection on the hip and knee to the standard of care test

This study aim to explore cellular responses of bone and immune cells to bacterial infections observed in patients with prosthetic joint infections. The investigators will analyze clinical data and tissue samples collected from patients undergoing surgery as part of their usual care for prosthetic joint infections. These research will be conducted on three different hospitals in Paris: Lariboisière (AP-HP), Cochin (AP-HP) and Croix Saint-Simon.

The aim of this trial is to study the interest of ultrasonography among patients with septic arthritis. Currently, ultrasonography is useful for detecting small fluid effusions, for examining otherwise inaccessible joints, such as the hip and for helping the joint aspiration. Accurate assessment of disease activity and joint damage in septic arthritis is important for monitoring treatment efficiency and for prediction of the outcome of the disease. Nowadays, magnetic resonance imaging (MRI) provides better resolution than radiography or tomography for the detection of joint effusion and for differentiation between bone and soft tissue infectious. The sensibility is reported to be nearly 100% with a specificity of more than 75%. However, MRI is expensive and not rapidly accessible. Therefore, ultrasonography, a non invasive, painless, inexpensive, and non radiating exam can be used to assess the presence and extent of inflammation, destruction, and tissue response. The objective is to describe, using ultrasonography, the abnormalities joint structure influenced the septic arthritis evolution and prognosis. The investigators hope, at the end of this study, to evaluate ultrasonography interest in septic arthritis and to establish ultrasonography prognosis factors to predict treatment efficiency and functional outcome.

The goal of this study is to figure out the best doses for two antibiotics (called cefadroxil and cephalexin) when they are used to treat bone, joint, or muscle infections in children. In order to do this, the study will collect data about children admitted to Children's Hospital Colorado who have these types of infections. During the study, these patients will receive doses by mouth of each of these antibiotics, in addition to an IV antibiotic (given through a vein) used to treat their infection. After the dose of the first antibiotic, blood samples will be drawn every few hours to measure how much of the drug is still in their body, until it is all gone. After the first antibiotic is out of the patient's body, the same will be done for the second antibiotic. Measurements, in the lab, of how much of these antibiotics are needed to kill the most common bacteria causing these infections, which is a type of "Staph" bacteria called "MSSA", will be taken. Finally, the blood levels of the antibiotics and the information from the lab tests about the Staph bacteria will be used to calculate how much and how often of the antibiotic should be given to children with bone, joint, or muscle infections. Currently, these types of infections are treated with an antibiotic that children have to take four times every day. The goal of this study is to find an antibiotic that children can take only two or three times per day.

The PROOF Study is an open prospective interventional non-randomized study which aim is to determine the outcome / effect and safety of fosfomycin in patients with hip, knee or shoulder PJI.
