About

Pyogenic liver abscess (PLA) is a complication of infectious disease, and the most common pathogen of PLA is Klebsiella pneumoniae, while PLA caused by Carbapenem-resistant Klebsiella pneumoniae (CRKP) has become a threat to public health. For achieving a better therapeutic outcome of CRKP related PLA, it is very important to figure out the basic characteristics and risk factors of CRKP-PLA.

A retrospective cohort study was performed in which 15 PLA patients carriage of K pneumoniae were screened at the Xiangya hospital of central south university (changsha, China). The colonization and clinical infection isolates were analyzed by antimicrobial susceptibility testing to identify CRKP. All admission patients diagnosed with PLA who developed CRKP were included, 5 adults PLA patients with CRKP infected and 10 adults PLA patients with Carbapenem sensitive Klebsiella pneumoniae (CSKP) infected were conducted. Univariate and multivariate logistic regression was carried out using a stepwise selection method to compare prognostic factors between CRKP and CSKP groups.

Enrollment: 15 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• 18 years of age or older. at least one positive culture reported by the clinical microbiology laboratory for CRKP or CSKP during the hospital length of stay.

Klebsiella pneumoniae were isolated and identified in the blood or pus with antibiotic drug sensitivity results.

Exclusion criteria

• Less than 18 years old. patients with missing data without a drug sensitivity results.

Trial design

15 participants in 2 patient groups

CRKP-PLA

Description:

Klebsiella pneumoniae were isolated from pyogenic liver abscess patients' blood or pus and the antibiotic drug sensitivity results shows it is carbapenem-resistant Klebsiella pneumoniae.

Treatment:

Diagnostic Test: drug sensitivity results

CSKP-PLA

Description:

Klebsiella pneumoniae were isolated from pyogenic liver abscess patients' blood or pus and the antibiotic drug sensitivity results shows it is carbapenem-sensitive Klebsiella pneumoniae.

Treatment:

Diagnostic Test: drug sensitivity results
