The Combination of Aztreonam-Avibactam in Multidrug-Resistant Gram-Negative Infections

Annals of Pharmacotherapy
Objective: Aztreonam-avibactam (ATM-AVI) is used for difficult-to-treat gram-negative infections. The objective of this review is to analyze the pharmacology, safety, and clinical application of ATM-AVI.

Aztreonam-avibactam: a new combination with activity against multidrug-resistant Klebsiella pneumoniae complex

The Journal of Antibiotics
Klebsiella pneumoniae complex (KPc) is a group of opportunistic pathogens that pose a serious threat to public health. Multidrug resistance is increasing, and limiting therapeutic options. Aztreonam-avibactam (AZA) is a combination of an established β-lactam with a new β-lactamase inhibitor.

Multiple mechanisms mediate aztreonam-avibactam resistance in Klebsiella pneumoniae: driven by KPC-2 and OmpK36 mutations.

International Journal of Antimicrobial Agents
Aztreonam-avibactam (ATM-AVI) is a promising β-lactam/β-lactamase inhibitor combination with an antimicrobial spectrum covering serine carbapenemase- or metallo-β-lactamase-producing Enterobacterales. Although ATM-AVI has not been widely used in clinical

Reduced susceptibility to aztreonam-avibactam conferred by acquired AmpC-type β-lactamases in PBP3-modified Escherichia coli.

European Journal of Clinical Microbiology & Infectious Diseases
Carbapenemase-producing Enterobacterales are a growing threat, and very few therapeutic options remain active against those multidrug resistant bacteria. Aztreonam is the molecule of choice against metallo-beta-lactamases (MBL) producers since it is not hydrolyzed by those enzymes, but the co-production of acquired plasmidic cephalosporinases or ...

Evaluation of the MTS™ aztreonam-avibactam strip (Liofilchem) on New Delhi metallo-β-lactamase-producing Enterobacterales

European Journal of Clinical Microbiology & Infectious Diseases
The combination of ceftazidime-avibactam (CAZ-AVI) and aztreonam (ATM) is used to treat MBL-producing Enterobacterales-related infections. The new combination aztreonam-avibactam (AZA) is currently in development. We compared results obtained with the new MIC test strip (MTS) AZA (Liofilchem) with broth microdilution method (BMD) on 41 MBL-producing ...

Hijacking a small plasmid to confer high-level resistance to aztreonam–avibactam and ceftazidime–avibactam

International Journal of Antimicrobial Agents, 2023
Acquired β-lactamase-encoding genes are typically carried by large plasmids in Gram-negative bacteria, which also commonly carry multi-copy small plasmids. This study found that mobile genetic elements carrying antimicrobial resistance genes are capable of hijacking small plasmids. This study focused on aztreonam-avibactam (ATM-AVI) as this combination
