Poor glycemic control and smoking and drinking history rather than bacterial virulence contribute to the development of invasive Klebsiella pneumoniae liver abscess: a case–control study in Northeast China
Case-control study examined glycemic control and lifestyle factors in liver abscess patients, indicating impact on disease severity.
Key Points
Invasive K. pneumoniae liver abscess is influenced by factors like diabetes and smoking history, not just bacterial virulence.
Independent risk factors identified include poor glycemic control, with a longer hospital stay for invasive cases compared to noninvasive.
Whole-genome sequencing and antimicrobial resistance testing were conducted on 50 strains, showing no significant differences in virulence between KPLA types.
Analysis suggests lifestyle and health conditions significantly affect the development of invasive liver abscesses from K. pneumoniae.
