Risk Factors for Pyogenic Liver Abscess With Carbapenem-resistant Klebsiella Pneumoniae: A Matched Case-control Study

Completed

• Conditions: Liver Abscess
• Interventions: Diagnostic Test: drug sensitivity results

• Registration Number: NCT05521139
• Lead Sponsor: Xiangya Hospital of Central South University

Brief Summary

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.
