Active clinical trials for "Communicable Diseases"

The microbiome of 80 orthopedic-device related infection (ODRI) patients treated with antibiotics and 10 healthy controls will be investigated. Samples (blood, stool, saliva, skin-swab) are collected 4x within 6 months. Composition and diversity of the microbiome will be assessed by 16sRNA sequencing, skins swabs are screened for rifampicin-resistant staphylococci onto Mannitol-salt-agar plates supplemented with rifampicin, inflammation markers and antibodies in blood and saliva are monitored to track changes in the immune response. For further analysis patients are assigned to one of two groups: 1) antibiotic therapy including rifampicin and 2) non-rifampicin antibiotic therapy.

Background Rapid European COVID-19 Emergency Research response (RECoVER), is a project involving 10 international partners that has been selected for funding by the European Union under the Horizon 2020 research framework responding to call topic SC1-PHE-CORONAVIRUS-2020: Advancing knowledge for the clinical and public health response to the SARS-CoV-2 epidemic. MERMAIDS 2.0 is the hospital care study within RECOVER. Rationale Detailed patient-oriented studies are needed to determine the spectrum of SARS-CoV-2 disease and the combined influences of age, comorbidities and pathogen co-infections on the development of severe disease, together with virological and immunological profiles. This research is key to understanding the pathophysiology and epidemiology of this new disease, as well as to identifying potential targets for therapeutic or preventive interventions. Objective To establish the prevalence, disease spectrum and severity, clinical features, risk factors, spread and outcomes of novel 2019 coronavirus infection (SARS-CoV-2) in Hospital Care. Study design Prospective observational cohort study in selected European countries. Study population Children and adults with 1) acute respiratory illness (ARI) presenting to hospital care during the SARS-CoV-2 epidemic (including both COVID-19 and non-COVID-19 patients) and 2) patients with confirmed COVID-19 infection, but with atypical presentation (non-ARI) or with nosocomial acquisition. Sites can optionally participate in the following tiers: Tier 1 (Clinical data and biological sampling) - Clinical samples and data will be collected on enrolment day and then at scheduled time points. Tier 2 (Clinical data an extended biological sampling). - incl. PBMC collection Optional add-on study In a subset of sites and patients, COVID-19 positive patients will be followed post-discharge for 6 months to study clinical recovery and long-term sequelae Main study parameters/endpoints: Prevalence of COVID-19 among patients with acute respiratory illness. COVID-19 disease spectrum and host and pathogen risk factors for severity. Long-term sequelae of COVID-19 requiring hospital care. Proportion hospital-acquired COVID-19 infections and characteristics of nosocomial transmission. Study Duration Scheduled 2 years and based on COVID-19 dynamics. Nature and extent of the burden associated with participation, benefit and group relatedness This study is observational in nature. There will be no direct benefit to research participants. The study may include biological sampling in addition to sampling required for medical management. The results of the tests done on these samples may not contribute to improving the participant's health. Minimal inconvenience and discomfort to the participant may arise from study visits and biological sampling.

Retrospective laboratory-based data collection study of surgical site infections: Surveillance of Healthcare-Associated Infections in Orthopaedic and Trauma Surgery Unit in Sosnowiec, Poland;

The aim of this pilot study is to demonstrate the feasibility of viral biomolecular diagnosis in sputum compared to nasopharyngeal swab in cystic fibrosis acute respiratory infection.

This study will analyze gene expression data (HostDx Sepsis test) from blood samples collected from participants with suspected infections. The primary endpoint of the study is to prospectively validate the HostDx Sepsis test for infections. As a secondary endpoint the correlation of participant prognosis and gene expression results in the HostDx Sepsis test will be validated. Participants presenting to the emergency departments of enrolling sites with a suspected infection and 1 vital signs OR suspected sepsis and 2 vital sign changes as stated in the protocol are meeting enrollment criteria

One-step exchange arthroplasty is more and more used in the treatment of chronic infections, especially in patients at risk anesthetic. This strategy is not recommended in patients infected with multidrug-resistant organisms or difficult to treat because of a risk of bacterial persistence on the new implant. Antibiotic pretreatment by a narrow-spectrum molecule and for which resistance acquisition is difficult might be of interest to try to reduce the inoculum and avoid contamination of the new implant.

Study setting: Medellin and Bello municipalities, Colombia Health condition(s) studied: Dengue, Zika and chikungunya virus infection Intervention: Deployment of Wolbachia-infected Aedes aegypti mosquitoes in Medellin and Bello. Study design: An interrupted time-series analysis utilising routine disease surveillance data collected by the Medellín and Bello Health Secretariats, which aims to compare incidence of dengue, chikungunya and Zika pre- and post-Wolbachia release. A test-negative study using an incident case-control design, which aims to quantify the reduction in disease incidence among people living within a Wolbachia-treated zone compared with an untreated zone that has a similar dengue risk profile at baseline.

The Geneva Blood Virome Project is a longitudinal observational study. The main objective is to describe the kinetics of the plasmatic viral load of a selection of at least 21 DNA and RNA viruses of the blood virome in allogeneic hematopoietic stem cell transplant recipients, over a one-year period after transplantation. Secondary objectives are: 1) to assess the prevalence of DNA and RNA viruses plasmatic detections and co-detections, 2) to assess the cumulative incidence of DNA and RNA viruses plasmatic detection. The population of the study consists in adult patients receiving allogeneic stem cell transplantation at the University Hospitals of Geneva, enrolled in an already existing monocentric cohort, and for which clinical specimens are collected and stored at the time and after transplantation. The investigators plan to include 120 patients whose plasma samples are collected from March 2017 and to systematically use plasma samples collected on the day of transplantation and several time points after transplantation to screen DNA and RNA viruses by qualitative and quantitative real-time PCR and RT-PCR.

The aim is to explore the human urine composition and its relation to urine tract infections

The aim of the cohort prospective observational study is to define the major factors influencing the course of COVID-19 infections and its prognosis in hospitalised patients. The investigators plan to include 300 patients hospitalised with COVID-19 infection. The phone contacts with patients are due after 90 and 180 days after discharge.
