Filter by:The goal of this study is to evaluate the efficacy and safety of ceftazidime-avibactam(CAZ-AVI) in the treatment of critically ill patients with carbapenem-resistant organisms(CRO) infections (including dialysis patients and extracorporeal membrane oxygenation(ECMO) patients).
The emergence of multidrug-resistant organisms (MDROs) has become one of the major threats to the healthcare system in Hong Kong in recent years. The situation is particularly worrisome for carbapenem-resistant Enterobacteriaceae (CRE). Taking Queen Mary Hospital as an example, the number of CRE cases has surged from 24 in year 2014 to 625 in year 2021. The case burden in Hong Kong is therefore substantial when all 43 public hospitals and institutions in Hong Kong are considered. With the widespread use of broad-spectrum antibiotics and active case screening, the number of CRE cases is expected to further increase in an exponential manner. Given that colonization with MDROs is due to gut dysbiosis from antibiotic use, a normal intestinal microbiota is apparently crucial in protecting hosts from colonization with MDROs including CRE. Fecal microbiota transplantation (FMT), which involves the infusion of stool from a healthy donor to the gastrointestinal (GI) tract of a recipient, has gained popularity in recent years to restore colonic microbial diversity in various diseases associated with gut dysbiosis, e.g. Clostridium difficile (CD) infection, ulcerative colitis and even metabolic diseases. The investigators aim to conduct a double-blind randomized controlled trial to evaluate the benefit of FMT via lower GI delivery (enema) on CRE clearance.
Antibiotic resistance (AR) is a critical public health threat and one of the greatest challenges of the 21st century. In an estimate of 2019, nearly 700.000 infections and 33.000 attributable deaths from multi-drug-resistant bacteria (MDRB) have occurred in Europe in 2015. The gastrointestinal tract is a large reservoir for MDRB, and the gut microbiota can harbor a collection of AR genes, called gut resistome. Preliminary nonrandomized evidence suggests that fecal microbiota transplant (FMT) could be a promising treatment option to eradicate MDRB, but established evidence, as well as mechanisms that underpin this therapeutic pathway, are still unavailable. Leveraging our expertise in FMT (OU1), microbiome (OU2) and MDRB (OU3), we aim to evaluate the efficacy of FMT (from donors with limited presence of AR genes) in eradicating intestinal MDRB through a randomized controlled trial and identifying microbial features that are associated with clinical efficacy and clearance of AR genes
This is a randomized, open label, comparative Phase II trial being conducted to determine whether fecal microbiota transplant using Penn Microbiome Therapy (PMT) products helps standard therapy eradicate antibiotic-resistant bacteria.
Spread of extensively drug-resistant bacteria (XDR) such as carbapenemase-producing Enterobacterales (CPE) is a major public health problem. Various prevention and control interventions are implemented to limit the transmission of XDR but they are expensive and often disrupt hospital organization. In this study, a mathematical model will be used to study the effectiveness and cost-effectiveness of control strategies to limit the spread of CPE in a general hospital ward. A case-control study will be conducted to estimate the excess length of stay and mortality attributable to CPE colonisation or infection.
Worldwide emergence of extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-E) had become a major problem in ICU, with at least 10% of incidence at the admission in Europe. A systematic rectal swab is used in 70% of French ICU to detect intestinal ESBL-E carriage The relationship between intestinal carriage and ICU-acquired infection is not perfectly known. The investigators conducted a five years study monocentric retrospective observational cohort in patients with presence of extended-spectrum β-lactamase-producing Enterobacteriaceae in systematic rectal swabs to investigate which type of infections and which bacteria are involved. The investigators also collect data about antibiotherapy used to treat these infections.
Double-blinded, randomised controlled trial to evaluate the clinical efficacy of a single dose of oral capsule-administered faecal microbiota transplantation (FMT) for carbapenemase-producing Enterobacteriaceae (CPE) intestinal decolonisation compared with placebo. Primary outcome is the proportion of patients successfully decolonised of CPE intestinal carriage at 12 weeks after FMT treatment compared with placebo.
The purpose of this study is to evaluate the treatment outcomes in patients with CRE infections.
Extended-Spectrum Beta-Lactamases (ESBL)-Producing Enterobacteriaceae (PE) pose a major problem among antimicrobial resistance. The worldwide spread of theses bacteria may be responsible for 10 million death in 2050. Infection with ESBL-PE are associated with a worse prognosis because of delay in the start of adequate antibiotic treatment, especially for severe infections. It has been proposed to identify colonized patients to predict the risk of infection and the risk of nosocomial cross transmission. This qualitative approach has limit as only 5 to 20% of patients will develop an infection with ESBL-PE. The fecal relative abundance (RA) of ESBL-PE is a ratio of ESBL-PE among enterobacteriaceae that could identify high-risk patients of infection or cross transmission. ESBL-PE RA may be highly variable in patient with antibiotic exposure depending on the molecule received but dynamic data is missing. The aim of this study is to identify the factor that influence the fecal RA of ESBL-PE in ICU and to evaluate the association between different level of fecal RA and infection or cross transmission with an ESBL-PE.
This study explores the effect of probiotic administration to decrease colonization by Carbapenem resistant Enterobacteriaceae (CRE) in at-risk populations. Colonized patients will be randomized to receive probiotics or placebo for 14 days and reevaluated for colonization in follow up.
