Active clinical trials for "Bone Diseases, Infectious"

The purpose of this European, multicentric, prospective, non-interventional study is to document and evaluate the efficacy and safety of the treatment of severely infected patients with intravenously administered fosfomycin, including patients with osteomyelitis, complicated urinary tract infection, nosocomial lower respiratory tract infection, bacterial meningitis/central nervous system infection, bacteraemia/sepsis, skin and soft tissue infection, endocarditis or other infections, each as far as covered by the respective nationally relevant SmPC.

Currently the diagnosis of OA is based on radiographs and clinical findings, which is limited to detecting late-stage disease. There is a pressing, unmet clinical need for robust assessment of early changes in cartilage health. Towards this goal, extensive efforts are ongoing to develop quantitative MRI for cartilage matrix analysis. MR T1ρ and T2 relaxation times have shown to be promising imaging biomarkers for early cartilage degeneration and prediction of disease progression. However, many challenges remain to clinically applying these techniques, including lack of standardized acquisition and quantification methods, and long acquisition times. The study aims to develop novel, fast and reproducible MR T1ρ and T2 relaxation time imaging methods on MR systems from multiple vendors and establish a platform for standardization and cross validation of these measures as a tool for clinical trials using such techniques. Following method validation, patients at risk for osteoarthritis will be tested.

Tuberculosis (TB) is one of the top ten causes of death worldwide with approximately 10 million cases globally and 1.2 million deaths. Sub-Saharan Africa carries the highest burden of TB. South Africa has one of the highest HIV and TB rates worldwide with an HIV prevalence rate in adults of 19% and a TB case notification rate of 615/100,000 in 2019. Over many years, focus has been paid to pulmonary TB and extrapulmonary TB (EPTB) has received only little attention even though it accounts for almost a quatre of all TB cases. The diagnosis of EPTB remains challenging simply because sample collection requires invasive procedures in the absence of a blood-based diagnostic test. Spinal TB (spondylitis or spondylodiscitis caused by Mycobacterium tuberculosis) - often known as Pott's disease - accounts for up to 10% of EPTB and affects young children, people with HIV-coinfection and elderly, and often leads to lifelong debilitating disease due to devastating deformation of the spine and compression of neural structures. Little is known with regards to the extent of disease and isolated TB spine as well as a disseminated form of TB spine have been described. The latter presents with a spinal manifestation plus disseminations to other organs such as the lungs, pleura, lymph nodes, the GIT or urinary tract or even the brain. In the Spinal TB X cohort, the investigators aim to describe the clinical phenotype of spinal TB using whole body PET/CT and identify a specific gene expression profile for the different stages of dissemination and compare findings to previously described signatures for latent and active pulmonary TB. A blood-based test for spinal TB would lead to earlier diagnosis and treatment in all settings globally and improve treatment outcome of this devastating disease.

Debio 1450 is being developed for the treatment of staph (staphylococcal) infections. How fast and completely an antibiotic penetrates into bone is used to determine how effective it might be to treat infections related to bones or joints. Since bone has fewer blood vessels than other tissue (for example lung tissue or the skin), drugs have a harder time getting into them. It is important to find out how much of the antibiotic can get into the bone to help patients with bone infections.

Background. Bone infections can involve the vertebral column, intervertebral disc space, spinal canal and soft tissues, can generate neurological deficit in addition to the destruction of the bone that causes functional disability. Vertebral osteomyelitis is the most frequent, affecting 2 to 7 patients per 100,000 habitants. Management is bone debridement and bone reconstruction. Objective. Demonstrate that the use of bone allograft is a functional method to stabilize the spine after a bone spinal infection Material and methods. Patients with vertebral bone destruction are included in two groups. Bone allograft group will receive bone structural allograft; Auto and allograft group will receive bone structural allograft plus autograft. The bone reconstruction will be performed in a one-time surgical procedure. Bone consolidation, pain, functionality, and spine deformity will be evaluated.

Treatment of bone and joint infections remains difficult and variable according to centres and countries. Clindamycin given intravenously and followed by an oral route is recommended for the treatment of staphylococcal, streptococcal and anaerobes bone and joint infections by the French Society for Infectious Diseases. For staphylococcal bone and implant infections, rifampin is a major drug, as it remains active in bacterial biofilm and on quiescent staphylococci. For that reasons, clindamycin-rifampin combination therapy is frequently used in these infections.Clindamycin is metabolized by the P450 3A4 cytochrome, an enzyme strongly inducible by rifampin. A retrospective study published in 2010 on 70 patients treated for bone and joint infections showed that clindamycin serum concentrations were significantly lower when clindamycin was combined with rifampin (5.3 mg/liter vs 8.9 mg/liter; p<0.02). This drug interaction could even be stronger with the oral route, because of hepatic first-past effect, ending up with very low clindamycin serum concentration, a risk of selecting resistant microorganisms and treatment failure. This latter point is an important issue, because clindamycin has an excellent oral bioavailability and is frequently used in oral regimens. In the above study, a wide variability of clindamycin serum concentration was observed in the group of patients treated with combination therapy (1-12mg/l) suggesting interindividual variability. Rifampin induction of CYP 450 3A4/A5 depends on different receptor (PXR, RXR, LXRalpha) submitted to genetic polymorphism. Hypothesis: Plasma clearance of clindamycin (CLclin) combined with rifampicin (CLclinrif) is higher when clindamycin is administered by the oral route (CLclinrif OR) compared with IV administration (CLclinrif IV).

Multicenter study allowing to include the first sixty patients implanted with a custom-made corpectomy implant (UNiD 3D VBR): 30 patient implanted in cervical region and 30 patients implanted in thoracolumbar region. The main objective is to confirm feasibilty and safety of patient-specific implants for one or multi-level corpectomy and fusion. This study was approved in March 2016 allowing to include retrospectivley all patients since the first implantation in January 2015 and prospectively all patients after the approval.

Only 24 cases of Campylobacter bone and joint infection (BJI) have been reported worldwide between 1955 and 2008. Between 2010 and 2012, 7 cases were observed in two University hospitals in France. This increasing number of cases raises several issues. Are they the consequences of better detections and reporting, or are they reflecting any epidemiologic changes? For answering these questions, we performed a 10 year (2002-2012) retrospective multicenter (6 centers) study on BJI (native and implanted joints) due to Campylobacter species.

Pressure ulcer represents a frequent clinical condition in patient with spinal cord injury or after prolonged Intensive Care Unit (ICU) stay. Osteomyelitis constitutes a severe complication with a poorly known management, and is associated with a high rate of relapse, leading to a high-burden in hospital bed-days, financial cost, surgical intervention, antibiotic use, morbidity and mortality, and nursing care. In our reference center for bone and joint infection management, the medical and surgical strategies are systematically discussed during pluridisciplinary meetings. Most patients benefit from a two-stage surgical strategy (debridement with initiation of vacuum-assisted closure therapy until reconstruction using muscular flap) with prolonged antimicrobial therapy. In this context, our study aims to evaluate this complex approach and to determine risk factors of treatment failure in order to improve patient management, focusing on optimization of empirical antimicrobial therapy after each surgical stage, delay between the two surgical stage, and duration of antimicrobial therapy.
