Active clinical trials for "Infections"

This study is a prospective, single center, observational, cohort study of patients to determine whether the Mologic Biomarker Panel can identify patients with infection from those without, including those with other reasons for inflammation (e.g. post-operative). It will also assess whether it has the potential to judge the severity of illness, prognosticate outcome and guide antibiotic therapy. The aim is to recruit patients who are "representative" of patients with suspected sepsis, uncomplicated infection, or non-infection related critical illness that require critical care intervention and assessment. This study is observational and will not alter patient management or the standard of care. The results from the investigational Mologic Biomarker Panel and associated research assays will not be provided to treating clinicians, or used in any manner to affect patient care. The study will take place over approximately an 18-month period and it is anticipated that approximately 600 patients will be collectively enrolled. The study aims to recruit patients from three environments within UCLH: The Emergency Department. Critical Care Unit Patients undergoing major surgery

To establish a pathology reference laboratory for the consultation on the diagnosis of infectious diseases and lymphoma. To study the specific pathogens on 100 cases of unexplained death due to infectious diseases in the files of Taiwan CDC and the Forensic Institutes of Department of Law and Justice. To study the distribution of children lymphoid lesions in Vietnam and Taiwan and their virus association. To establish a tissue bank for infectious diseases and lymphoma.

Re-infection of the liver graft occurs universally following liver transplantation for HCV-induced end stage liver disease. Interestingly, the manifestation of HCV infection ranging from an asymptomatic carrier state to rapid progression to liver cirrhosis is extremely variable from one patient to another. The host and viral factors being responsible for the different course of HCV infection are poorly understood. Our study will focus on dendritic cells which are known to play a critical role in the control of viral infection. Viral factors (quasispecies evolution) will also be analysed and Th1 Th2 cytokines produced in the serum evaluated.Thirty liver transplanted patients will be included : 20 patients transplanted for HCV-related disease and 10 controls transplanted for non HCV-related disease. Blood samples will be taken just before transplantation and at different time -points up to 5 years after transplantation. Function of blood monocyte-derived DC will be evaluated. Circulating blood plasmacytoid (pDC) and myeloid DC (mDC) sub-populations will be enumerated. HCV quasispecies evolution will be analysed. This study may help to define prognostic markers on progression of hepatitis C in liver transplantation and allow the development of new immunotherapeutic drugs

The purpose of this study is to assess the cut-off value of GM/G test in Chinese patients after hematopoietic stem cell transplantation, and evaluate GM/G test and real-time PCR for diagnosis of IFI in Chinese patients.

Purpose of the study is to investigate and quantify known and possible new riskfactors for nosocomiel infection and death in the intensive care setting. As new riskfactors Mannose Binding Lechtin and Procalcitonin are chosen and compared to established riskfactors.

Our study involved 142 children with EV71 CNS infections that included 61 (43%) with viral meningitis, 53 (37%) with severe CNS involvement including encephalitis, polio-like syndrome and encephalomyelitis, and 28 (20%) with cardiopulmonary failure after CNS involvement. These children were subjected to physical and neurological examinations 2.85 (range 1.0-7.39) years after disease onset. Those below the age of 6 years took the Denver developmental screening test, while those 4 years and over took the intelligence quotient (IQ) test.

Focusing on patients with diabetes complicated with pulmonary infection, the purpose of this study is: 1) to identify the epidemiology, etiologic spectrum and status of diagnosis and treatment; 2) to develop a symptom score scale , clarify the risk factors and create a precise warning model; 3) to develop a rapid detection of pathogen of lower respiratory infection, to establish clinical pathways of early diagnosis and treatment of diabetes complicated with pulmonary infections (including bacterial, tuberculosis and fungal infections) and then make an application in clinic.

Antibiotic resistance is a serious and increasing worldwide threat to global public health. One of antibiotic stewardship programmes' objectives is to reduce inappropriate broad-spectrum antibiotics' prescription. Selective reporting of antibiotic susceptibility test (AST) results, which consists of reporting to prescribers only few (n=5-6) antibiotics, preferring first-line and narrow-spectrum agents, is one possible strategy advised in recommendations. However, selective reporting of AST has never been evaluated using an experimental design. This study is a pragmatic, prospective, multicentre, controlled (selective reporting vs usual complete reporting of AST), before-after (year 2019 vs 2017) study. Selective reporting of AST is scheduled to be implemented from September 2018 in the ATOUTBIO group of 21 laboratories for all E. coli identified in urine cultures in adult outpatients, and to be compared to the usual complete AST performed in the EVOLAB group of 20 laboratories. The main objective is to assess the impact of selective reporting of AST for E. coli positive urine cultures in the outpatient setting on the prescription of broad-spectrum antibiotics frequently used for urinary tract infections (amoxicillin-clavulanate, third generation cephalosporins and fluoroquinolones). The primary endpoint is the after (2019) - before (2017) difference in prescription rates for the previously mentioned antibiotics/classes that will be compared between the two laboratory groups, using linear regression models. Secondary objectives are to evaluate the feasibility of selective reporting of AST implementation by French laboratories and their acceptability by organising focus groups and individual semi-structured interviews with general practitioners and laboratory professionals.

The purpose of this study is to evaluate the clinical significance of community-acquired respiratory virus (CARV) infection in patients with lung transplantation;Explore the lung microbiome dynamics within one year after lung transplantation;Find the relationship between lung microbiome and chronic lung allograft dysfunction(CLAD).

The present research aims to collect virological and clinical data on hepatitis E virus (HEV) infections, either in acute or chronic forms of HEV infection in North-Eastern France, with liver- or non liver-related symptoms, plus data on HEV circulation in the outside environment. The purpose of this study is to improve the diagnosis and care of HEV-infected patients, as well as the preventive features to take into account in order to avoid food- and environment-borne infections. At last, we will investigate HEV molecular characteristics, with the hypothesis that some advantageous HEV strains coul be more pathogenic for some tissues and/or organs.
