Management of Intra-abdominal Infections due to Carbapenemase-Producing Organisms

Area of Science:

• Infectious Diseases
• Microbiology
• Surgical Infections

Background:

• Increasing bacterial resistance to carbapenem antibiotics is a significant global health concern.
• Metallo-β-lactamases (MBL) are a primary mechanism driving resistance, leading to carbapenemase-producing organisms (CPO).
• Carbapenem-resistant Enterobacteriaceae (CRE) are a growing cause of complex infections, including intra-abdominal infections (IAIs).

Purpose of the Study:

• To summarize current and emerging multimodal strategies for managing IAIs caused by CRE.
• To review existing data on combined interventions aimed at reducing the burden of CRE infections.
• To highlight the need for updated international guidelines endorsed by surgical and infectious disease societies.

Main Methods:

• Review of updated international treatment guidelines for IAIs and CRE-related IAIs.
• Synthesis of data on multimodal management approaches for CRE infections.
• Analysis of evidence for combination therapies in combating CRE.

Main Results:

• Updated guidelines provide a framework for managing IAIs due to CRE.
• Multimodal approaches and combination therapies show promise in reducing CRE.
• Further research is needed to evaluate novel antimicrobial therapies and infection control effectiveness.

Conclusions:

• Management of IAIs due to CRE requires a comprehensive, multimodal approach.
• Combination interventions and updated guidelines are crucial for effective treatment.
• Future research should prioritize novel therapies, infection control quantification, and rapid diagnostics.
