Active clinical trials for "Communicable Diseases"

The IDIS study aims to develop a new rapid diagnostic test for invasive salmonellosis using samples (blood, urine) collected from patients with fever and healthy controls at the Institute of Tropical Medicine (ITM) and collaborating centers. The samples are collected after informed consent and/or assent is given by the participant and are stored in a -80 ⁰C freezer after processing (centrifugation and/or aliquoting). Basic information regarding the patient and the samples are coded and stored in a protected Microsoft Access database. The samples will be shipped to Belgium for proteomic analysis. Identification of Salmonella specific proteins in the samples will hopefully support the development of a rapid diagnostic test. Once this test has been developed, the samples will also be used for validation and evaluation of this test.

Cervical cancer is due to a persistent infection with a group of viruses known as high-risk Human Papillomaviruses (hrHPV). Viral DNA can be easily detected in a cervical sample by a procedure called 'HPV testing', which can be used as a relevant screening test. A pilot screening program called START-HPV has been set up in the Ardennes, a French administrative area localized in the North of France, with HPV testing as a primary screening test.This observational study aimed to evaluate hrHPV genotypes repartition in the population who participate in the START-HPV screening program. This study will allow a better knowledge of hrHPV infection epidemiology in a screened population.

Corynebacterium spp have been considered as innocuous commensals of human skin, but are now accepted as important opportunistic pathogens responsible for various nosocomial infections, especially implicating foreign materials. In particular, they accounted for up to 10% of prosthetic joint infection (PJI), and are mostly identified in chronic forms of bone and joint infections (BJI). However, little is known about the pathophysiological pathway implicated in Corynebacterium BJI, species distribution and antimicrobial susceptibility, and the management of these difficult-to-treat clinical entities. This study aims to report a retrospective cohort of patients with Corynebacterium spp BJI, aiming to : i) describe microbiological characteristics of the implicated clinical isolates, including species identification and antimicrobial susceptibility (and especially according to previous antimicrobial exposure); ii) assess pathophysiological mechanisms associated with BJI chronicity, including biofilm formation and bone cell invasion, to better understand mechanisms of Corynebacterium spp and to evaluate their ability to distinguished colonizing and infective isolates; iii) describe the medical (nature and duration of antimicrobial therapy) and surgical management of these patients; and iv) evaluate the patient outcome according to this management strategy, and highlight risk factor for treatment failure in order to improve patient's management.

The determinants associated with severe outcome and death from Escherichia coli bloodstream infections (BSI) remain poorly understood. The epidemiology of E. coli BSI has recently changed dramatically with the global emergence of multiresistant strains producing extended-spectrum ß-lactamases (ESBL). Outcome is worse in case of ESBL-E. coli, which may be due to the intrinsic virulence of ESBL-E. coli or to a delayed adequate empirical antibiotic therapy because of multiresistance. Predicting the severity of an infection as soon as the initial clinical assessment is of major importance to provide the best care, while limiting unnecessary hospitalizations and costs. Yet, no simple clinical score exists to predict the severity of E. coli infections. In a translational approach, the investigators will include during a maximum of one year 500 adults with E. coli BSI hospitalized in 7 hospitals in the Paris area, France. Precise clinical data will be collected at inclusion and 28 days after inclusion or upon patient's discharge (if before day 28). The primary endpoint of the study is death from E. coli BSI at day 28. The first aim is to determine risk-factors for death at day 28, including clinical and bacteriological factors (determined by WGS) in the era of the global emergence of ESBL producing E. coli. The second aim is to determine virulence characteristics of ESBL strains both at the genome and phenotypic level thanks to a mouse model of septicaemia, and compare them to the clinical data. The third aim, will establish and evaluate a simple clinical severity score (named COLISCORE), in order to help clinician evaluate patients' severity upon initial clinical evaluation and particularly to detect patients at risk of severe outcome. The ultimate goal of this work is to have a clinical impact on patients' management, by understanding the determinants of patient severity due to E. coli BSI in the context of current major epidemiological changes.

Epidemiology of Helicobacter Pylori Infection Among Shanghai Children.

primary purpose:Evaluate the prevalence and incidence of HPV infection and related diseases in subjects. Secondary purpose:Analyze risk factors of HPV infection and related diseases.

The Transplant Infectious Diseases Prospective Cohort Study facilitates the prospective identification and collection of data of infectious disease complications in order to determine the epidemiology, risk factors, and outcomes of patients who receive solid organ or stem cell or plastic surgery transplants at Johns Hopkins and other transplant centers. It is essential for the care and treatment of this population to employ a mechanism for investigators to centralize these datasets, using standardized definitions of infectious complications. This protocol outlines the procedures to be utilized in order to prospectively follow the diagnosis and treatment of infectious complications in transplant patients.

This trial studies hepatitis B screening strategies of new cancer patients scheduled to undergo chemotherapy. Patients with cancer and hepatitis B virus infection are at risk of reactivation of infection after chemotherapy. Hepatitis B virus infection reactivation can be prevented by starting antivirals before chemotherapy in patients who are hepatitis B virus infection positive. Hepatitis B screening may help doctors prevent the reactivation of hepatitis B virus infection after chemotherapy.

A non-interventional study to assess incident rates of Osteonecrosis of the Jaw and Infections leading to hospitalization in Cancer patients treated with XGEVA™ in Sweden, Denmark and Norway.

This is a pilot study which aims to show the temperatures measured on body surface with an infrared thermometer on inpatients who need a central venous catheter (CVC) for medical care. Because the local temperature could be altered, at least during local infectious processes, seems to be reasonable to think that this approach could be helpful to its early diagnosis.
