View clinical trials related to Enterobacteriaceae Infections.
Filter by:Enterobacteriaceae, more specifically Escherichia coli and Klebsiella pneumoniae, are the bacteria most often responsible for neonatal infections in low-income countries. Infections caused by multidrug-resistant Enterobacteriaceae: Extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-E), are more often associated with an unfavorable outcome of the infection. Enterobacteriaceae colonize the digestive tract which is the first step in developing a potential infection. Very few studies have been carried out at the community level. Colonization of the mother with ESBL-E is generally considered to be a major route of acquisition. The carrying of ESBL-E by other family members and other potential sources of transmission (food, objects and surfaces in contact with the newborn) have never been documented. In addition, with a view to offering an intervention adapted to the local context, the local cultural determinants which govern the interactions of the newborn with his environment are important to understand.
Infections caused by carbapenemase-producing Enterobacteriaceae are frequent and often associated with high rates of mortality. Colonized patients are at increased risk of infection for these microorganisms. Moreover, they can act as a reservoir facilitating the transmission to other patients. To date, decolonization strategies with antibiotics have not obtained convincing results. For that reason our main objective is to investigate the efficacy of fecal microbiota transplantation (FMT) for selective intestinal decolonization of patients colonized by KPC-producing Klebsiella pneumoniae (Kp-KPC) at 30 days after FMT. Our hypothesis is that FMT is effective and safe for selective intestinal decolonization in patients colonized by Kp-KPC. The design of the study is a randomized, superiority, double blind controlled with placebo clinical trial. The main variable is the percentage of patients with intestinal decolonization at 30 days after FMT in intention to treat population (all randomized patients). Decolonization will be considered as the abscence of isolation of Kp-KPC in culture from rectal swab together with the abscence of detection of carbapenemase by mean of polymerase chain reaction. Secondary objectives are: - To evaluate the safety of FMT. - To determine if FMT is associated with decrease in the amount of bacteria at 7 days after FMT and 30 days after FMT. - To evaluate if FMT is associated with persistent intestinal decolonization at 3 months after intervention. - To study if FMT is associated with decrease in the incidence of Kp-KPC infections at 3 months after intervention. - To evaluate if FMT is associated with decrease in mortality due to Kp-KPC infections at 3 months after intervention.
Rates of antimicrobial resistance are increasing worldwide. There is increasing evidence that physiological gut microbiota is a large reservoir of antibiotic-resistance genes. Healthy gut microbiota is known to prevent the colonization of the gastrointestinal tract by pathogens, the so-called mechanism of colonization resistance, but this protective mechanism can be altered by therapies that impair gut microbiota, including antibiotics or chemotherapeutics, with consequent colonisation of gut pathogens, including multi-drug resistant bacteria (MDRB). MDRB carriers represent an epidemiological threat to other hospitalized patients and to the whole community, but are also at risk of developing clinical consequences of this colonization, including bloodstream infections from these pathogens. Fecal microbiota transplantation (FMT) has shown high efficacy in the eradication of recurrent C. difficile infection, and initial evidence suggests that this procedure could be useful in eradicating also MDRB, mainly carbapenem-resistant Enterobacteriaceae. However, current evidence is mostly limited to case reports and case series, and to a single randomised trial, which was stopped early and did not draw clear conclusion. In a systematic review of 21 studies and 192 patients, eradication rates ranged from 0% to 100%, and authors concluded that larger, well designed randomised controlled trials are needed to further explore this therapy. The aim of this study is to investigate the efficacy of FMT, compared with placebo FMT, in eradicating gut colonisation from MDRB, focusing on CRE. The investigators will randomize patients colonized by CRE (diagnosed by rectal swab) to FMT from healthy donors or placebo, by colonoscopy. Then, patients will be followed up, rectal swabs will be repeated, and stool samples for culture and microbiome analysis will be collected, up to 3 months after FMT.
The purpose of this study is to assess the effect of fecal microbiota transplantation for the decolonization of carbapenem-resistant Enterobacteriaceae or vancomycin-resistant Enterococci in the gut.
Carbapenem-resistant Enterobacteriaceae (CRE) are increasingly identified in children in China. Pediatric intensive care unit (PICU) is the high-risk area. However, data on the epidemiology of CRE in hospitalized children in PICU are limited. The objectives of this study are to characterize the risk factors for colonization or infection with CRE and describe the microbiologic characteristics of pediatric CRE isolates. The investigators will perform a single retrospective study from January 2018 to December 2019 at PICU of Children's Hospital of Fudan University .
Antimicrobial resistance is a major threat worldwide and now concerns last-ressource antibiotics such as carbapenems. As the resistance to carbapenems is directly due to their use, their spare has become a public health emergency. Their efficacy in ventilator-associated pneumonia has never been compared to other classes of antibiotics such as piperacillin-tazobactam which can be an alternative to carbapenems.
The gut microbiota is critical to health and functions with a level of complexity comparable to that of an organ system. Dysbiosis, or alterations of this gut microbiota ecology, have been implicated in a number of disease states. Fecal microbiota transplantation (FMT), defined as infusion of feces from healthy donors to affected subjects, is a method to restore a balanced gut microbiota and has attracted great interest in recent years due to its efficacy and ease of use. FMT is now recommended as the most effective therapy for CDI not responding to standard therapies. Recent studies have suggested that dysbiosis is associated with a variety of disorders, and that FMT could be a useful treatment. Randomized controlled trial has been conducted in a number of disorders and shown positive results, including alcoholic hepatitis, Crohn's disease (CD), ulcerative colitis (UC), pouchitis, irritable bowel syndrome (IBS), hepatic encephalopathy and metabolic syndrome. Case series/reports and pilot studies has shown positive results in other disorders including Celiac disease, functional dyspepsia, constipation, metabolic syndrome such as diabetes mellitus, multidrug-resistant, hepatic encephalopathy, multiple sclerosis, pseudo-obstruction, carbapenem-resistant Enterobacteriaceae (CRE) or Vancomycin-resistant Enterococci (VRE) infection, radiation-induced toxicity, multiple organ dysfunction, dysbiotic bowel syndrome, MRSA enteritis, Pseudomembranous enteritis, idiopathic thrombocytopenic purpura (ITP), and atopy. Despite FMT appears to be relatively safe and efficacious in treating a wide range of disease, its safety and efficacy in a usual clinical setting is unknown. More data is required to confirm safety and efficacy of FMT. Therefore, the investigators aim to conduct a pilot study to investigate the efficacy and safety of FMT in a variety of dysbiosis-associated disorder.
This study evaluates the efficacy in achieving clinical cure in non-bacteremic urinary tract infections (UTI) caused by Escherichia coli or Klebsiella pneumoniae producers of extended-spectrum β-lactamases (ESBL) in adult patients. Half of participants will receive Piperacillin/Tazobactam as treatment, while the other half will receive Carbapenems. The investigators will verify that Piperacillin/Tazobactam is not inferior in achieving clinical cure, and that is not associated with a higher risk of adverse events in the directed treatment of non-bacteremic UTI compared to Carbapenems. The researchers hope to improve the use of antibiotics in the non-bacteremic UTI, reducing the "collateral damage" related to a deterioration in the prognosis of patients and the generation of resistant germs caused by the use of broad-spectrum antibiotics as carbapenems.
Data regarding optimal treatment for extended-spectrum beta-lactamase (ESBL) producing Enterobacteriaceae blood-stream infection are lacking. Observational studies show conflicting results when comparing treatment with combination beta-lactam-beta-lactamase inhibitor and carbapenems. The investigators aim to evaluate the effect of definitive treatment with meropenem vs. piperacillin-tazobactam on the outcome of patients with bacteremia due to cephalosporin-non-susceptible Enterobacteriaceae. The investigators hypothesize that piperacillin-tazobactam is non-inferior to meropenem.
This is an open-label dynamic whole-body PET/CT (positron emission tomography/computed tomography) study for investigation of radiation dosimetry, plasma pharmacokinetics, biodistribution, safety and diagnostic performance of 18F-FDS in healthy volunteers and patients with suspected infection. A single dose of nearly 370 MBq 18F-FDS will be intravenously injected into healthy volunteers and patients with suspected infection. Visual and semiquantitative method will be used to assess the PET/CT images. Changes of blood pressure, pulse, respiration, temperature, routine blood and urine tests, serum alanine aminotransferase, albumin, and creatinine, and any adverse events will be collected from the volunteers. Adverse events will also be observed in the patients.
