Active clinical trials for "Communicable Diseases"

The aim of this retrospective observational study is to evaluate the efficacy of antibiotic therapy with dalbavancin in patients presenting with infection on prosthetic devices. The main questions the study aims to answer are: What is the proportion of patients with early discontinuation of dalbavancin therapy? What are the reasons for early discontinuation of antibiotic treatment? What adverse events do patients report? The study is based on data collected as part of routine care practices.

Kidney transplantation is the best method of renal replacement in patients with irreversible renal failure. One of the biggest problems today is premature loss of function of the transplanted kidney. This occurs most often on the basis of chronic humoral rejection. This is the immune response to the kidney, in which the specific antibodies play a crucial role (both against the HLA and the non-HLA system). The aim of this study is to analyze one of the situations where the production of antibodies can begin to occur. This is a serious acute infection (bacterial, viral, or fungal), where it is necessary to significantly reduce doses of immunosuppressives. At the time of reduced immunosuppression, the immune system can recognize the transplanted kidney as foreign to the human body and begin to fight against it. In this study, the investigators will monitor antibodies against the transplanted kidney in patients with severe acute infection. A serious infection in this study is one that requires acute hospitalization and reduced doses of immunosuppressive drugs. The researchers will measure the antibodies in the blood upon admission and then in 5 weeks.

Retrospective, regional, multicenter study (including the Annecy-Genevois Hospital Center, the Chambéry Métropole Savoie Hospital Center, and the Grenoble University Hospital Center), comparing a cohort of patients treated with Cefazolin with a cohort of patients treated with Penicillin M

A retrospective, observational analysis of the first one hundred consecutive cases of bacteriophage therapy of difficult-to-treat infections, facilitated by a Belgian consortium.

The aim of this cohort study is to validate Viture®, a continuous temperature telemonitoring system, evaluating the level of agreement with a standard commercially available digital axillary thermometer. The study also aims to evaluate the safety and comfort of the system and to evaluate the impact that the introduction of Viture has on the health care practice of a HaH unit. Furthermore, the advantages of Viture compared to the standard method will be evaluated.

Multicentre, observational, retrospective study to analyze the differences in CMVi pattern and recurrences between two groups of allogeneic HSCT patients (haplo vs no haplo HSCT), with intervention both postransplant cyclophosphamide as GvHD prophylaxis, using a database with information from historical clinic data.

Infection with Streptococcus pneumoniae (the pneumococcus) is the leading cause of pneumonia, bacterial meningitis and bacteraemia worldwide in the very young and the elderly. Although pneumococcal vaccines exist, they do not provide complete protection and new strategies to combat this pathogen are urgently needed. Asymptomatic infection of S. pneumoniae in the human nasopharynx precedes the development of pneumococcal disease. Previously, an Experimental Human Pneumococcal Carriage (EHPC) model has been developed at the Liverpool School of Tropical Medicine (LSTM). The current study entails to establish this model in healthy adults living in the Netherlands using the inoculation dose currently used at LSTM. Healthy adult participants (M/F) will be inoculated intranasally with strain BHN418, a penicillin sensitive serotype 6B strain of S. pneumoniae that was previously isolated from a healthy carrier. Following inoculation, participants will be monitored and blood and nasal samples will be collected over a period of 28 ± 3 days. Participants will receive a course of amoxicillin to eradicate infection on or shortly after the last visit at day 28 ± 3, unless S. pneumoniae is not detected on both day 14 and 28 ± 3 post-inoculation.

Lower respiratory tract infection(LRTI) is a prevalent disease that threatens the health of older people worldwide. Anemia is also a common disorder in the elderly, and its prevalence increases significantly with age. Most factors that contribute to the development of anemia are improvable. Therefore, we investigated whether anemia was a risk factor for LRTI-caused readmission and death in the elderly occurring within 1 year of discharge from the hospital.

Progress in the diagnosis of infectious pathogens depends on the development of effective methods and the discovery of suitable biomarkers. There are several kinds of methods that have been used in diagnosis of various pathogens, such as microscopic examination, culture, serologic diagnosis or molecular approaches, etc. However, these methods have similar limitations, that is, the single detection of reagents. More importantly, physicians seldom consider infections with rare pathogens. Recently developed metagenomic next-generation sequencing (mNGS) has the capability to overcome limitations of traditional diagnostic tests. This new technology could identify all pathogens directly from sample with a single run in a hypothesis-free and culture-independent manner. Studies have shown that mNGS is more sensitive than traditional culture method in clinical conditions such as blood stream, respiratory and general infections. More importantly, due to unbiased sampling, mNGS is theoretically able to identify not only known but also unexpected pathogens or even discovery novel organisms. It should be noted that mNGS also has some limitations such as human genome contamination and possibly environmental microbial contamination. The vast majority of reads in mNGS are derived from human host. This would impede the overall analytical sensitivity of mNGS for pathogen detection. Host depletion methods or targeted sequencing may help to partially mitigate this disadvantage. As mNGS could not, by itself, define whether the detected microbe is the causative pathogen or environmental microorganism, a multidisciplinary discussion by clinicians, microbiologists as well as the lab technicians is required to interpret the result.

This post-marketing surveillance (PMS) study for Sovaldi® tablets (sofosbuvir, SOF) administered in combination with Copegus® tablets (ribavirin, COPE) will evaluate the safety and efficacy of SOF administered in combination with ribavirin under real world use in Japan. Among adult patients with chronic genotype 2 hepatitis C virus (HCV) infection and treated with SOF+ribavirin in routine clinical use, the primary objective of this study is to evaluate the incidence of adverse drug reactions (ADRs) under real world settings.
