Active clinical trials for "Infections"

The purpose of this study is to better estimate the prevalence of urinary tract infections (UTI) in kidney transplant (KIT) recipients, and especially multidrug resistant (MDR) bacteria. KIT recipients have a higher risk of UTI over the 6 first months following the transplantation. Urine culture was done in a city lab or at hospital. Current data on bacteriuria and candiduria lead mostly to hospital data that are incomplete..

Patients undergoing elective abdominal surgery will be included prospectively. Informed consent will be obtained. Preoperatively baseline health data is collected and a skin swab and rectal swab for baseline skin and gut microbiota is taken. During the surgery additional clinical data and additional samples will be obtained. Additional samples include: rectal swab, biopsies of the resected specimen (lymph node, peritoneum, intestinal content, mucosa), venous blood sample (7.5ml) at the end of the operation, liver biopsy and skin biopsy. Postoperative health data is recorded. If a surgical site infection occurs a swab is taken too. With 16 sRNA (small ribonucleic acid) based sequencing the investigators will quantify the abundance of the different bacterial species in all samples. Primary outcome will be to assess a difference of 16sRNA signal in the liver and lymph node biopsies between patients with and patients without surgical site infection. Secondary outcomes include variables predicting the occurence of surgical site infections and a model describing the way bacteria may take to cause wound infection.

This study is to establish an accurate, robust and easily scalable COVID-19 viral nucleic acid analysis platform from, but not limited to, saliva to help enable and support contact tracing in the canton of Baselland/ Switzerland. To achieve this, crude ribonucleotide acid (RNA) extraction from saliva is validated in combination with next-generation sequencing (NGS) diagnostics and loop mediated amplification (LAMP) assays as well as point of care test (POCT) for rapid detection of viral antigens on patients' samples.

Strengthening outpatient low respiratory tract infection surveillance to document the burden of Respiratory Syncytial Virus (RSV)

The SARS-Cov2 pandemic remains associated with many concerns. One of the them is the real frequency of likely re-infection and subsequently the level of protection conferred by the acquired immunity following primary-infection. We propose to analyze a large set of laboratory data produced since the early beginning of the SARS-Cov2 spread in the French population to identify recurrent infection events and, more generally, gain insight about infection kinetics.

After 7 then 13 valent pneumococcal conjugate vaccine implementation in France in children, we will evaluate the impact of this vaccination on invasive pneumococcal disease (IPD). We will describe the clinical characteristics of IPD, pneumococcus serotyping, underlying conditions and vaccination status.

Lower Respiratory Tract infections are a common cause of admission to the intensive care unit. Children routinely receive antibiotics until the tests confirm whether the infection is bacterial or viral. The exclusion of bacterial infection may take 48 hours or longer for culture tests on biological samples to be completed. In many cases, the results may be inconclusive or negative if the patient has already received antibiotics prior to the sample being taken. A rapid assay to detect the most likely cause of infection could improve the speed with which antibiotic therapy is rationalised or curtailed. This study aims to assess whether a new genetic testing kit which can identify the presence of bacteria and viruses within hours rather than days is a feasible tool in improving antibiotic prescribing and rationalisation of therapy in critically ill children with suspected lower respiratory tract infection.

A prospective multicenter cohort study on all types of revision knee arthroplasty procedures performed due to infection.

The focus of this prospective observational study is to (1) establish the range and variation associated with bone/soft tissue perfusion in fracture patients, using ICG fluorescence imaging; (2) examine the relationship between perfusion and complications such as surgical site infection (SSI), persistent SSI, and fracture nonunion; (3) to determine whether the quantitative ICG fluorescence can be used to guide bony debridement in the setting of infected fracture to minimize complications.

This prospective, multicenter, non-interventional trial aims to study the association between TTV viral load and the occurrence of rejection or infection during the first year after transplantation. The TTV viral loads, taken once a month during the first year after the transplant, will be measured at the end of the study.
