Resumen de Cefiderocol
Mari Cruz Soriano, Jessie Montufar, Aaron Blandino Ortiz
Cefiderocol is a new siderophore cephalosporin with potent in vitro activity against gram-negative bacilli including Enterobacterales that produce all kinds of carbapenemases and non-fermenting Gram-negative with difficult-to-treat resistance. As a β-lactam, its efficacy is optimized in extended-perfusion and requires dose adjustment in renal dysfunction and hyperclearance. Its efficacy has been validated in three clinical trials, one of them in the treatment of hospital-acquired pneumonia and ventilator-associated pneumonia. The clinical trial aimed at difficult-to-treat gram-negatives achieved the clinical and microbiological target, but the increase in mortality observed in the cefiderocol arm makes it necessary to demonstrate efficacy in real clinical practice. Cefiderocol is a good option among the new β-lactams for the treatment of pneumonia caused by Gram-negative bacilli carbapenem-resistant.
