Cefiderocol for Infections Caused by Multidrug-Resistant Gram-Negative Bacteria

Nursing for Women's Health, 2020
In 2019, the U.S. Food and Drug Administration approved cefiderocol, a new treatment option for individuals with complicated urinary tract infections. Cefiderocol is a cephalosporin antibiotic indicated for use in adults 18 years or older who have minimal treatment options due to resistance for complicated urinary tract infections caused by Escherichia

EnvZ mutation-driven downregulation of catecholate siderophore receptors and concurrent TonB complex repression confer cefiderocol resistance in a KPC-Producing ST11-KL64 Hypervirulent Klebsiella pneumoniae.

International Journal of Antimicrobial Agents
Cefiderocol is an ultimate antibiotic option for Carbapenem-resistant hypervirulent Klebsiella pneumoniae (CR-hvKP). While resistance often involves metallo-β-lactamases, mechanisms in KPC-producing strains are unclear. This study used in vitro evolution

Emergence of cefiderocol resistance mediated by blaAFM-1 overexpression and FptA mutations in clinical Carbapenem-Resistant Pseudomonas aeruginosa isolates.

Clinical Microbiology and Infection
OBJECTIVES This study evaluated the in vitro activity of cefiderocol against clinical carbapenem-resistant Pseudomonas aeruginosa (CRPA) isolates in China prior to its clinical introduction, and investigated the mechanisms underlying resistance ...

Pharmacokinetic evaluation of cefiderocol for the treatment of multidrug resistant Gram-negative infections

Expert Opinion on Drug Metabolism & Toxicology, 2022
Cefiderocol is a siderophore cephalosporin antibiotic and first of its kind approved by the Food and Drug Administration for the treatment of complicated urinary tract infections (cUTI) and hospital-acquired and ventilator-associated bacterial pneumonia (HABP/VABP) in patients 18 years or older caused by susceptible organisms.

Unexpected natural cefiderocol resistance in Stenotrophomonas maltophiliaassociated to the genogroup 4 genetic background.

Clinical Microbiology and Infection
OBJECTIVES Stenotrophomonas maltophilia (Sm) is responsible for infections among immunocompromised and hospitalized patients. Its genomic diversity led to the description of a large complex including numerous genogroups.

Spanish nationwide survey of Pseudomonas aeruginosa cefiderocol susceptibility and resistance mechanisms

International Journal of Antimicrobial Agents
Cefiderocol is a new siderophore-cephalosporin showing potent activity against Pseudomonas aeruginosa, including isolates showing extensively drug-resistant (XDR) or difficult-to-treat resistant (DTR) phenotypes. However, there is still a limited understanding of the potential resistance mechanisms.

Cefiderocol: A Comprehensive Review of Chemistry, Mechanisms of Resistance, and Clinical Applications in the Era of Multidrug Resistance

Current Microbiology
The global spread of multidrug-resistant (MDR) Gram-negative bacteria, particularly carbapenem- and colistin-resistant strains, represents a critical public health crisis with limited therapeutic options. Cefiderocol, a first-in-class siderophore cephalosporin, addresses this challenge through an innovative Trojan horse mechanism.
