Antibiotic heteroresistance in Klebsiella pneumoniae : Definition, detection methods, mechanisms, and combination therapy
Copyright © 2024 Elsevier GmbH. All rights reserved..
Klebsiella pneumoniae is a common opportunistic pathogen that presents significant challenges in the treatment of infections due to its resistance to multiple antibiotics. In recent years, K. pneumoniae has been reported for the development of heteroresistance, a phenomenon where subpopulations of the susceptible bacteria exhibit resistance. This heteroresistance has been associated with increased morbidity and mortality rates. Complicating matters further, its definition and detection pose challenges, often leading to its oversight or misdiagnosis. Various mechanisms contribute to the development of heteroresistance in K. pneumoniae, and these mechanisms differ among different antibiotics. Even for the same antibiotic, multiple mechanisms may be involved. However, our current understanding of these mechanisms remains incomplete, and further research is needed to gain a more comprehensive understanding of heteroresistance. While the clinical recommendation is to use combination antibiotic therapy to mitigate heteroresistance, this approach also comes with several drawbacks and potential adverse effects. In this review, we discuss the definition, detection methods, molecular mechanisms, and treatment of heterogenic resistance, aiming to pave the way for more effective treatment and management in the future. However, addressing the problem of heteroresistance in K. pneumoniae represents a long and complex journey that necessitates comprehensive research efforts.
