Active clinical trials for "Klebsiella Infections"

The purpose of this study is to review patients with E. coli infections at the University of Pittsburgh Medical Center (UPMC) from September 1, 2006 to August 31, 2007 to determine if these infections have arisen in the community rather than in hospitals or nursing homes. The occurrence of such resistant isolates could be devastating if they were associated with bloodstream infection, such as sometimes accompanies a urinary tract infection, since antibiotic resistant E. coli is not suspected in isolates coming from the community. Therefore, the aims of this study are to: Review whether extended-spectrum beta-lactamase (ESBL)-producing organisms (E. coli, Klebsiella species and Proteus species) are hospital-acquired, healthcare-associated, or community-associated. Investigate the prevalence of ESBL-positive E. coli in foodstuffs (beef, poultry, turkey, and pork), as a potential source for ESBL producers in the community. Compare the clonal relationship of the genome and resistance plasmids carried by the ESBL-producing isolates (healthcare-associated, community-associated, and of animal origin) and study the associations of ESBL-mediated resistance with resistance to other classes of antimicrobials.

To determine whether the restriction of 3rd generation cephalosporins and carbapenems contribute to the reduction of intestinal colonization or infection with vancomycin-resistant enterococci (VRE) in a medical intensive care unit (MICU).

COMBAT trial was contemplated to elucidate unknown clinical relevance of carbapenem heteroresistance among Klebsiella pneumoniae species. Bloodstream infections, type of frequently seen invasive infections that pathogen isolation, identification of antimicrobial resistance mechanisms can be performed efficiently, with carbapenem resistant Klebsiella pneumoniae (CRKp) and carbapenem hetero-resistant Klebsiella pneumoniae will be compared in terms of relevant clinical outcomes such as 30-day mortality rate, 14-day clinical cure rate, 7-day microbiological eradication rate and 90-day relapse/re-infection rate. In addition, underlying molecular resistance mechanisms causing carbapenem hetero-resistance among Klebsiella pneumoniae isolates will be investigated by using whole genome sequences.

Klebsiella pneumoniae is one of the most common pathogens causing both community-onset and nosocomial infection. More worse, the emergency of Carbapenem-Resistant Klebsiella pneumoniae (CRKP) had cause the clinical therapy be very difficult. However, there is not much empirical data as to the prevalence, risk factors, characteristics,outcomes and the rationality of the current therapy for the Klebsiella pneumoniae infection in China.Thus, the study was aimed to investigate the epidemiology and risk factors, characteristics, outcomes and the rationality of the current therapy for the Klebsiella pneumoniae infection in China.

Klebsiella pneumoniae is one of the most common pathogens causing nosocomial infection. Recently, the emergency of Carbapenem-Resistant Klebsiella pneumoniae (CRKP) had cause the clinical therapy be very difficult. However, there is not much empirical data as to the prevalence, risk factors, characteristics, and the rationality of the current therapy for the CRKP infection. Thus, the study was aimed to investigate the epidemiology and risk factors, characteristics, and the rationality of the current therapy for the CRKP infection.

Nosocomial infections are increasing rapidly both internationally and domestically, especially carbapenem-resistant Klebsiella pneumoniae infections. However, there were still lack of evidence about the risk and prognosis in Taiwan. The choice of drug and related sensitivity test was also limited. We would analyze the infection risk, prognosis, and drug sensitivity of Klebsiella pneumoniae and focus on strategy to manage carbapenem-resistant Klebsiella pneumoniae infections.
