Active clinical trials for "Infections"

Interferon gamma release assays (IGRA) have been shown to be more specific and sensitive for the detection of tuberculosis (latent or active infection) than the tuberculin skin test (TST) in immunocompetent individuals. However, very little data are available concerning the relative performance of IGRA and TST in immunosuppressed individuals from other causes than HIV. The investigators hypothesize that IGRAs would be more sensitive and specific than the TST in a group of renal transplant recipients under chronic immunosuppressive treatment for detecting latent tuberculosis infection.

This is a prospective cohort study of persons tested for latent tuberculosis infection at either high risk for exposure to Mycobacterium tuberculosis or high risk for progression to tuberculosis disease. The study will assess the relative performance and cost of three diagnostic tests for latent tuberculosis infection (tuberculin skin test, QuantiFERON-TB Gold In-Tube, and T-SPOT.TB) and will examine the rates of positive results among the cohort. This study will also determine the risk and rate of progression to active TB disease, overall and by the results of the three tests.

The investigators want to find out if there is any difference between the microbiotic flora lining the conjunctiva of medical staff that work in the hospital and others who do not work in the hospital.

This prospective observational study examines the associations of presence, duration, type, number and location of surgical drains with the risk of surgical site infections in a contemporary and multicentric cohort of general, orthopedic trauma and vascular surgery procedures.

This study is designed to identify the burden associated with HIV and its treatment, and assess their health-related quality of life (HRQoL) by measuring key HRQoL domains, including satisfaction with treatment and care, and internalised stigma (ISAT). The study will also explore data for various important subpopulations such as subjects who are virally suppressed; who we anticipate will be the majority of study subjects. The study design is an observational, cross sectional study employing subjects' own mobile phone devices for data entry.

Data extraction from bacteriological laboratory of Martinique University hospital to determine the frequency and the distribution of nosocomial infections due to Achromobacter xylosoxidans (ACHX), an emerging multi-resistant environmental bacteria. The specific tropical environment and climatic conditions in Martinique may favor ACHX development and the investigators suppose that this new opportunistic pathogen can represent a danger for hospitalized patients. The aim of our study is to describe the most affected population and try to identify the main environmental sources of contamination.

Implantation of joint prostheses is currently the second largest diagnosis-related group in the Danish health service, and in view of the demographic development and spread of lifestyle diseases, this type of intervention is expected to continue to increase. Unfortunately, 5% of patients experience significant discomforts and complications. The second most frequent and serious complication is infection. While the established laboratory analyses (culture of tissue biopsies) are good at diagnosing acute infections, they are not satisfactory to diagnose a large group of patients especially with chronic infections. This can lead to prolonged diagnosing time and even to wrong diagnosis. Several studies have shown that analyses of prosthetic parts and the use of molecular biological methods for detecting infecting microorganisms can significantly improve diagnostics accuracy. The purpose of this project is primarily to demonstrate that analyses of bacterial specific DNA (16S rRNA genes) can confirm or rule out infection as fast (or faster) as cultivation methods. Rapid clarification can promote targeted treatment and in order to demonstrate this, the trial is conducted as a randomized study. .

Web-based survey to colorectal surgeons assessing knowledge, beliefs and practices regarding the use of preventative measures for SSI.

Prospective, multi-site, study to evaluate the diagnosis rate of DNA and RNA sequencing of cerebrospinal fluid for identification of pathogens directly in patients who have already had a spinal tap to evaluate for infection and were found to have a pleocytosis. Diagnostic rate and clinical utility of concurrent standard testing will be compared to diagnostic rate and clinical utility of DNA and RNA sequencing.

The main objective of this project is to evaluate the agreement between nasopharyngeal and sputum specimens in terms of detection of viral infection in Cystic Fibrosis (CF) participants.This is a 12-month national, multicenter prospective study (7 centers). Inclusions concern CF participants (children or adults) with signs of acute respiratory infection seen in consultation or hospitalized in their CF Research Center. A molecular viral multiplex search is performed on both nasopharyngeal and expectoration collected samples for each included participant. Determination of viral detection agreement between the two CF respiratory samples is then performed.
