Abstract
This review provides an overview of recent research and advancements in infection prevention and the treatment of drug-resistant bacterial diseases. Cefiderocol, a novel siderophore cephalosporin, has demonstrated effectiveness against carbapenem-resistant bacteria such as Pseudomonas aeruginosa and Acinetobacter baumannii. Clinical trials, including APEKS-NP and CREDIBLE-CR, affirm its efficacy for hospital-acquired pneumonia (HAP) but highlight concerns over increased mortality due to severe renal complications. Cefiderocol has shown superior outcomes in complicated urinary tract infections (cUTI) compared to imipenem-cilastatin. A comparison of colistin monotherapy versus combination therapy with meropenem for carbapenem-resistant infections revealed no significant improvement in clinical outcomes with combination therapy but noted delays in resistance development. Colistin-rifampicin combination therapy showed potential benefits for colistin-resistant Acinetobacter baumannii, although results were not statistically significant. SPR206, a polymyxin derivative, and durlobactam, a β-lactamase inhibitor, show promise in addressing these resistant strains, with durlobactam demonstrating efficacy in combination with sulbactam and imipenem-cilastatin. Additional studies investigated antibiotic strategies for resistant infections, including cefoperazone-sulbactam versus combination therapy with tigecycline, and examined infection-prevention strategies in surgical settings, comparing chlorhexidine-alcohol and povidone-iodine. This research highlights the importance of optimizing treatment regimens and infection-control measures across various healthcare settings, including neonatology and surgical care.
