Introduction:
Management of antimicrobial resistance in multi-drug-resistant-Klebsiella pneumoniae (MDR-KP) is a major challenge for clinicians. The optimal treatment option for MDR-KP infections is still not well established. Combination therapies including high-dose meropenem, colistin, fosfomycin, tigecycline, and aminoglycosides are widely used, with suboptimal results. New antimicrobials targeting MDR-KP have been developed during the last decades and are now at various stages of clinical research. Areas covered: The PubMed database was searched to review the most significant literature on the topic, with a special consideration for articles coming from endemic countries. Expert commentary: We reviewed the currently available treatment options, discussing the characteristics of new antibiotics with activity against MDR Gram-negative bacteria and the strategies for preventing the spread of MDR-KP. While we wait for real-world data from novel compounds, coordinated strategies and common efforts in infection control and stewardship programs remain the cornerstone for limiting, or potentially reversing, conditions that favor the spread of MDR-KP.
Insights
Managing multi-drug-resistant Klebsiella pneumoniae (MDR-KP) infections is challenging. Current treatments yield suboptimal results, necessitating new strategies and infection control to combat antimicrobial resistance.
Area of Science:
- Microbiology
- Infectious Diseases
- Pharmacology
Background:
- Antimicrobial resistance in multi-drug-resistant Klebsiella pneumoniae (MDR-KP) presents a significant clinical challenge.
- Optimal treatment strategies for MDR-KP infections remain poorly defined, with current combination therapies showing suboptimal efficacy.
Purpose of the Study:
- To review current treatment options for MDR-KP infections.
- To discuss novel antibiotics with activity against MDR Gram-negative bacteria.
- To explore strategies for preventing the spread of MDR-KP.
Main Methods:
- A comprehensive literature search of the PubMed database was conducted.
- Emphasis was placed on studies from countries where MDR-KP is endemic.
- The review focused on significant literature regarding MDR-KP management.
Main Results:
- Existing combination therapies (meropenem, colistin, fosfomycin, tigecycline, aminoglycosides) offer limited success.
- New antimicrobials targeting MDR-KP are in various stages of clinical development.
- Effective infection control and stewardship programs are crucial for limiting MDR-KP spread.
Conclusions:
- Coordinated strategies and robust infection control are essential for managing MDR-KP.
- Novel compounds show promise, but real-world data are pending.
- Stewardship programs play a vital role in mitigating the conditions favoring MDR-KP proliferation.
