Active clinical trials for "Prosthesis-Related Infections"

The purpose of this study is to examine the efficacy of a dilute betadine solution in reducing infectious complications in revision total knee arthroplasty. The investigators will enroll patients who are scheduled to undergo a revision total knee arthroplasty. Patients will be randomized into two groups. The treatment group will receive a dilute betadine lavage prior to surgical closure for 3 minutes followed by 2000ml of sterile saline irrigation and the control group will receive the 2000ml sterile saline lavage alone.

To evaluate the efficacy of a castor bean-based solution (Ricinus communis) for removal of complete denture biofilm, comparing it with two products available on the market (sodium hypochlorite and alkaline peroxide). Fifty complete maxillary denture-wearers were instructed to brush their dentures after meals and once a day, for a period of 07 days, immerse them in the following solutions: A - Control: Physiological solution(20 minutes). B - Polident alkaline peroxide(3 minutes). C - 1% sodium hypochlorite(20 minutes). D - castor bean-based solution(20 minutes). The participants immersed their dentures in each of the solutions, according to a randomized sequence. For biofilm quantification, before (Baseline) and after the use of each product, the internal surfaces of maxillary complete dentures were revealed (1% neutral red), photographed and the stained biofilm was quantified with the aid of software (Image Tool 3.0). After concluding measurements of the areas (total and biofilm), the percentage of surface covered by biofilm of the complete denture was calculated .

Joint replacement is a valuable surgical intervention that improves quality of life, provides pain relief, and restores function of patients. However, some patients need revision surgery due to failure of the implant, with periprosthetic joint infection (PJI) remaining a rare but serious complication following total hip (THA) and knee (TKA) arthroplasty. Diagnosing PJI is a major challenge as no diagnostic test with absolute accuracy exists. The diagnosis is based on a combination of clinical findings, laboratory results from peripheral blood and synovial fluid, microbiological culture, histological evaluation of periprosthetic tissue, and intraoperative findings. However, the preoperative diagnosis can be inconclusive and operative criteria are required for the definitive diagnosis. Therefore, novel diagnosing tools for identification of PJI are necessary. A recent study using a gene reporter assay, identified biomarkers in synovial fluid that define joint states in patients with osteoarthritis.However, no previous studies have investigated cellular signaling in synovial fluid of patients with PJI. With this study we want to explore the potential of a reporter gene assay of synovial fluid in patients with PJI and without PJI of their TKA and THA. Also, flow cytometry analysis of biological fluids has recently received increased attention as a potentially valuable method in diagnosing infections. For example, the method is already used to analyze urine samples for urinary tract infections. Recently, researchers have now also used this method to screen for the presence of bacteria. The most important limitation of flow cytometry analysis of synovial fluids for bacteria to date is that it is unclear as to which bacteria count value - the cutoff value - represent patients with PJI and which represent patients without PJI. With this study we want to explore the potential of flow cytometry analysis of synovial fluid in categorizing patients with PJI and without PJI. Our primary objective is to explore the value of synovial fluid analysis using a reporter gene assay and flow cytometry in the detection of a periprosthetic joint infection.

The number of patients requiring joint replacement is increasing due to its success in restoring function and pain relief, and the growing population of the elderly. One of the most serious complications of arthroplasty is joint prosthesis infection. Due to the absence of prospective, randomized, controlled studies, there is no consensus concerning diagnosis and treatment of prosthetic joint infections. The main objective of this trial is to evaluate the clinical efficacy of rifampin combination therapy versus monotherapy using cloxacillin or vancomycin in early staphylococcal infections after total hip and knee arthroplasty.

The primary purpose of this study is to compare the re-infection rates in patients undergoing 2-stage revision arthroplasty who receive additional oral antibiotic therapy to those patients who received in-hospital perioperative antibiotic only. Patients will be monitored for re-infection following hospital discharge, defined as deep infection of the joint space/capsule that requires return to the operating room within 24-months of the re-implantation procedure.

The aim of this retrospective observational study is to evaluate the efficacy of antibiotic therapy with dalbavancin in patients presenting with infection on prosthetic devices. The main questions the study aims to answer are: What is the proportion of patients with early discontinuation of dalbavancin therapy? What are the reasons for early discontinuation of antibiotic treatment? What adverse events do patients report? The study is based on data collected as part of routine care practices.

Total knee arthroplasty (TKA) infection is a complication requiring multiple hospitalizations, operations, and outpatient visits placing a significant burden on both patient and treating surgeons. When revision surgery is needed, two kinds of treatment can be applied----one-stage and two-stage reimplantation procedure. The two-stage reimplantation procedure is considered the gold standard for treatment of subacute and chronic deep periprosthetic infections. Placement of antibiotic-loaded spacer is a standard procedure for eradication of peri-prosthetic joint infection. For better patient outcome, the purpose of this study was to determine the success rate of total knee infection patients treating with two-stage reimplantation procedure.

Infections often occur after ventricular assist devices (VADs) are placed. These infections can be very serious. The goal of this study is to understand why these infections occur. Bacteria (germs) normally live on our skin and in our noses. After surgery, they can infect the VAD. The investigators will collect cultures of your skin and nose before and after surgery. The investigators will compare these bacteria to bacteria that cause infections. Their genes will be compared to see which ones help the bacteria cause infection.

The purpose of the study is to evaluate the concentrations of antibiotics used as empirical treatment in serum and periprosthetic tissues during reimplantation of infected hip and knee prostheses

This is a prospective, randomized, blinded clinical trial to determine if the Air Barrier System device reduces the incidence of surgical site infection after total hip replacement, acetabular repair, posterior spinal fusion, and prosthetic vascular graft procedures.
