Filter by:The goal of this observational study is to learn about the risk factors of mortality for CRKP infected patients, and to compare the clinical outcomes between hvCRKP infection and cCRKP infection. The main question it aims to answer is • Whether hypervirulence would add value to cCRKP infection and cause worse outcomes? Participants data will be collected through medical records.
In this study, the tetravalent bioconjugate candidate vaccine Kleb4V will be tested to obtain first-time-in-human (FTIH) data on its safety and immunogenicity in healthy adults.
Carbapenem-resistant Klebsiella pneumonia (CRKp) blood stream infections (BSI) cause substantial mortality among hospitalized patients. Treatment options for CRKp infections are limited and increasing resistance rates to few available drugs, i.e., colistin, is a big concern. This prospective multicenter observational study is designed to describe clinical characteristics and outcomes of patients with CRKp bacteremia in an oxacillinase-48 (OXA-48) endemic country to define predictors of mortality with a focus on the impact of mono versus combination therapies on mortality. The study will also investigate risk factors associated with colistin-resistant CRKp BSI.
An observational two-center case-control study exploring the clinical impact of double-carbapenem use in a population of critically il patients with severe carbapenem-resistant Klebsiella pneumoniae infection
The identification of all cases (44 patients) was carried out from the database of microbiology, University Hospital Reina Sofía and the University Hospital of Jerez. For the identification of controls, in case of neutropenic patients, all colonized patients that were included during the study period did not receive any decolonitation treatment; in case of non-neutropenic patients it was studied a paired control by the presence of risk factors that indicated the beginning of decolonitation treatment.
Background: Klebsiella pneumoniae liver abscess is the most common etiology of liver abscess in Singapore and much of Asia, and its incidence is increasing. Current management includes prolonged intravenous antibiotic therapy, but there is limited evidence to guide oral conversion. The implicated K1/K2 capsule strain of Klebsiella pneumoniae is almost universally susceptible to ciprofloxacin, an antibiotic with high oral bioavailability. Our primary aim is to compare the efficacy of early (<1 week) step-down to oral antibiotics, to continuing 4 weeks of intravenous antibiotics, in patients with Klebsiella liver abscess. Methods/Design: The study is designed as a multi-centre randomised open-label active comparator-controlled non-inferiority trial, with a non-inferiority margin of 12%. Eligible participants will be inpatients over the age of 21 with a CT or ultrasound scan suggestive of a liver abscess, and Klebsiella pneumoniae isolated from abscess fluid or blood. Randomisation into intervention or active control arms will be performed with a 1:1 allocation ratio. Participants randomised to the active control arm will receive IV ceftriaxone 2 grams daily to complete a total of 4 weeks of IV antibiotics. Participants randomised to the intervention arm will be immediately converted to oral ciprofloxacin 750mg twice daily. At week 4, all participants will have abdominal imaging and be assessed for clinical response (CRP <20 mg/l, absence of fever, plus scan showing that the maximal diameter of the abscess has reduced). If criteria are met, antibiotics are stopped; if not, oral antibiotics are continued, with reassessment for clinical response fortnightly. If criteria for clinical response are met by week 12, the primary endpoint of clinical cure is met. A cost analysis will be performed to assess the cost saving of early conversion to oral antibiotics, and a quality-of-life analysis will be performed to assess if treatment with oral antibiotics is less burdensome than prolonged IV antibiotics. Discussion: Our results would help inform local and international practice guidelines regarding the optimal antibiotic management of Klebsiella liver abscess. A finding of non-inferiority may translate to the wider adoption of a more cost-effective strategy that reduces hospital length of stay and improves patient-centered outcomes and satisfaction.
There has been a great increase in the incidence of infections caused by bacteria that are resistant to antibiotic agents. Many of these infections result in worse outcomes of patients and increased costs to the healthcare system. The study aims to survey two germs that are resistant to a wide range of antibiotics used today. The investigators are particularly interested in studying the potential to stop the spread and prevent outbreaks of these germs through contact isolation of patients affected by these germs. Patients will be included in the study if they have an antibiotic resistant infection caused by any of the 2 bacteria: E. coli and K. pneumoniae. The research team will then perform rectal, skin (armpit, groin, umbilicus), throat, urine, and, if applicable, wound cultures to determine other sites where the germ may be present but not causing an infection. The study coordinator will furthermore examine the patient's medical record and conduct a short interview in order to evaluate specific information about the bacteria that have been recovered. This research does not involve any interventions beyond collection of specimens and there are no added risks to the patients from the conduction of the study. Neither will there be a benefit at the patient level. The benefit will be at the level of the patient population, i.e. at a larger scale once the information collected is analyzed. Only the principal investigator and study coordinators will have access to all patient-specific information. Once all information is collected, all patient identifiers, such as name and medical record number, will be deleted.
Klebsiella pneumonia, inhabitant of the digestive tract, is a frequent nosocomial pathogen. It is currently the fourth most common cause of pneumonia and fifth most common cause of bacteremia in intensive care patients (1-3). The aim of the present randomized controlled trial is to assess the efficacy of non-absorbable oral antibiotics in the eradication of the KPC carrier state.
This is a retrospective descriptive study on the clinical and microbiological features of Klebsiella Pneumoniae Necrotizing Fasciitis.
This is a retrospective chart review. This proposed study aims to document the risk factors for quinolone resistance in bloodstream isolates of Klebsiella species. Additionally, the adequacy of empiric antibiotic therapy for Klebsiella bloodstream infections will be assessed.
