Active clinical trials for "Communicable Diseases"

Aortic or large arterial vessel infections are rare but serious infections. Their management is based on French and American expert opinions. The quality of evidence supporting these guidelines is low because most publications on the subject correspond to case series and few interventional studies have been performed to validate their management. However, referral centres for vascular surgery are frequently solicited to give their opinion on patients suffering from mycotic aneurysms. In addition, the last few decades have seen the improvement of vascular surgery techniques allowing the management of more and more patients, often elderly and comorbid. There has therefore been an increase in the incidence of infectious complications associated with this care. It is therefore essential to participate in research on aortic and large arterial vessel infections. For this, a monocentric cohort study seems to be an essential first step to better understand the polymorphism and complexity of these patients.

The BK virus (BKV) belongs to the Polyomaviridae family. The primary infection, generally asymptomatic, occurs during childhood. The virus then persists in latent form in the body, mainly in the epithelial cells of the kidney and urinary tract. Cellular immunosuppression favors BKV replication. It is responsible for pathologies of the renal-urinary tract such as BKV-associated nephropathy (BKVAN) in kidney transplant recipients, hemorrhagic cystitis (HC) in hematopoietic stem cell (HSC) recipients or ureteral stenosis. To date, there is no specific antiviral treatment against BKV. The management of patients is essentially symptomatic and requires a multidisciplinary approach. It is therefore necessary to identify early prognostic markers for the occurrence of CH and to develop new therapeutic strategies.

To assess Family-unit Helicobacter Pylori Infection rates and antimicrobial resistance rates in Jiangsu,China

Cefiderocol is a new antibiotic from the siderophore cephalosporin family for which there are few real-life data on its use in the treatment of infections with multidrug-resistant Gram-negative bacilli. The circulation of bacterial strains multi-resistant to antibiotics is important at the Strasbourg University Hospital, so the investigators wish to report their local experience of the 1st uses of Cefiderocol in the treatment of infections with multi-resistant Gram-negative bacilli to antibiotics in order to better clarify the use of this antibiotic (therapeutic indication, method of administration)

The purpose of this study is to find differences in rates of surgical site infections following emergency laparotomy with the use of two different incisional negative pressure wound therapy (iNPWT)devices.

This study is observational, retrospective and prospective study in pediatric patients hospitalized with invasive streptococcal A infection

This study is a cross-sectional study that examines the prevalence of Latent Tuberculosis Infection [LTBI], defined as individuals infected with Mycobacterium tuberculosis with no clinical evidence of disease, and the possible risk factors of LTBI in a large cohort of health care workers (HCWs) and students.

The microbiome, the collection of microorganisms that live in our gut, plays an important role in maintaining our health, proper nutrient absorption, nutrient turnover and immunity. After birth, a symbiotic relationship develops with the strains of bacteria that colonise our gut, and the presence and proportion of bacteria is individualised and highly variable. A healthy bacterial flora is essential for the cells of the intestinal mucosa. Glycoproteins in the cell surface mucus coat are important nutrients for bacteria, while some bacterial strains supply mucosal cells with nutrient molecules (e.g. short-chain fatty acids) that are their essential energy source. An abnormal change in the proportion of bacterial strains that make up the microbiome, dysbacteriosis, in which pathogenic bacteria proliferate at the expense of members of the normal flora, can cause a number of pathologies. Nutrient supply to the cells of the mucosa is reduced, making them more vulnerable and leading to various pathological conditions. The microbiome and the essential nutrients they produce have also been found to play an important role in wound healing. A decrease in the diversity of the microbiome, an increase in the relative number of pathogenic bacteria and a decrease in the proportion of 'beneficial' bacteria increases the risk of surgical complications of infection and suture failure.

Relying on fever clinics, this project evaluates the clinical diagnostic efficiency of the three-level pathogen diagnostic system, monitors changes in respiratory pathogens, and realizes real-time monitoring and early warning of acute respiratory infectious diseases in Shanghai.

This is the protocol that formalizes the establishment of the TROPICA-BIOBANK biobank
