Reduce susceptibility to cefiderocol in gram negative bacteria in children: Is hope already lost before it's even arrived? J Infect Public Health 2024; 17:624-631. [PMID: 38422857 DOI: 10.1016/j.jiph.2024.02.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2023] [Revised: 01/28/2024] [Accepted: 02/07/2024] [Indexed: 03/02/2024] Open
Abstract
BACKGROUND In last years the diffusion of carbapenem resistance in Gram-negative bacteria (CR-GNB) is increasing worldwide, mainly due to the expression of carbapenemases. Cefiderocol has molecular characteristics that ideally confers activity against all CR-GNB, but resistant strains have already been identified. We describe cefiderocol susceptibility profile among multi-drug resistant Gram-negative isolated from pediatric patients. METHODS Prospective, single pediatric center study, 1st January 2020-15th June 2023. All GNB carbapenemases producers or phenotypically carbapenem-resistant isolated in the study period were tested for cefiderocol susceptibility. Clinical and microbiological data were collected. A descriptive analysis was performed, comparing the groups of cefiderocol-resistant vs. cefiderocol-susceptible Enterobacterales and non-fermenting Gram-negative bacteria (NF-GNB). RESULTS Forty-seven GNB were tested for cefiderocol susceptibility; 38% were cefiderocol-resistant: 16/30 (52%) among Enterobacterales and 2/17 (12%) among NF-GNB. None of the patients were previously exposed to cefiderocol. Looking at Enterobacterales, resistance to ceftazidime/avibactam was higher among cefiderocol-resistant vs. cefiderocol-susceptible strains (62% vs 36%, respectively), as MBL expression (67% vs. 36%, respectively). Too few NF-GNB were cefiderocol-resistance to draw any conclusion. No difference in ICU admission and mortality was identified comparing cefiderocol-resistant vs. susceptible strains. Patients colonized/infected by cefiderocol-resistant strains had been previously hospitalized more frequently. CONCLUSION In our cohort cefiderocol resistance was mostly registered among Enterobacterales, and especially among MBL producers' strains (that were alongside resistant to ceftazidime/avibactam). This could be explained by the known possible cross resistance mechanism among ceftazidime/avibactam and cefiderocol. Also, correlation of cefiderocol-resistance with previous hospitalization could be associated with horizontal resistance transmission. Looking at our data, we believe that cefiderocol should be use cautiously, especially empirically and in monotherapy, due to the high resistance rate.

[PMID: 38419283 PMCID: PMC10913069 DOI: 10.1002/cnr2.1982] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 12/06/2023] [Accepted: 12/28/2023] [Indexed: 03/02/2024] Open
Abstract
BACKGROUND Stenotrophomonas maltophilia is a bacterial pathogen that can be fatal in hospitalized and immunocompromised patients with mortality as high as 69%. Pediatric cancer patients often have risk factors that are common for this infection, making them particularly susceptible. Managing S. maltophilia is especially challenging as it has inherent resistance to several antibiotics. Furthermore, soft tissue infections in neutropenic patients may deviate from the typical clinical presentation of S. maltophilia. CASE DETAILS This case series describes an in-depth examination of three cases involving immunocompromised pediatric patients with S. maltophilia infections. Each case exhibited a distinct clinical presentation, encompassing infection of the blood, lung, and skin, which highlights the variability in which S. maltophilia manifests in immunocompromised pediatric patients. These patients were treated at MD Anderson Cancer Center (MDACC) from 2020 to 2023, unfortunately resulting in fatality. CONCLUSIONS The study aims to provide valuable insights and guidance for the management of patients with S. maltophilia infections. Emphasizing a heightened clinical suspicion will potentially lead to early initiation of directed therapy against S. maltophilia. Timely intervention may play a pivotal role in improving patient outcomes and reduce further burden to the healthcare system.

Real-Life Data on the Effectiveness and Safety of Cefiderocol in Severely Infected Patients: A Case Series. Infect Dis Ther 2023; 12:1205-1216. [PMID: 36943617 PMCID: PMC10029777 DOI: 10.1007/s40121-023-00776-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2022] [Accepted: 02/08/2023] [Indexed: 03/23/2023] Open
Abstract
INTRODUCTION Real-life data about cefiderocol use to treat extensively drug-resistant bacteria are scarce. We aim to report our early experience in patients with difficult-to-treat infections and limited therapeutic options. METHODS Patients treated with cefiderocol from March 2018 to April 2022 in a tertiary-care hospital in Spain were included. Demographic, clinical, and microbiological data were collected up to 90 days after the end of treatment or until death. Survival status was recorded at 30 and 90 days. RESULTS Ten patients were included, seven of them critically ill. Ventilator-associated pneumonia (40%) and bacteremia (40%) were the main infections. Multidrug-resistant or extensively drug-resistant P. aeruginosa was the most frequently isolated pathogen (70%, of which six patients were infected with bacteria with difficult-to-treat resistance), followed by A. baumannii, E. coli, and A. xylosoxidans (10% each). Seven patients received combination therapy. Clinical and microbiological cures were achieved in 90% and 80% of patients, respectively. Two previously susceptible strains (20%) developed resistance to cefiderocol. Overall, 30-day and 90-day mortality rates were 10% and 50%, respectively, although two out of five patients died due to the infection. No serious adverse events were reported, except for one patient who developed thrombocytopenia. CONCLUSION Cefiderocol seems to be an effective and safe rescue therapy for patients infected with difficult-to-treat pathogens, although there is a definite risk of the emergence of resistance.

Current and Potential Therapeutic Options for Infections Caused by Difficult-to-Treat and Pandrug Resistant Gram-Negative Bacteria in Critically Ill Patients. Antibiotics (Basel) 2022; 11:antibiotics11081009. [PMID: 35892399 PMCID: PMC9394369 DOI: 10.3390/antibiotics11081009] [Citation(s) in RCA: 18] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2022] [Revised: 07/15/2022] [Accepted: 07/24/2022] [Indexed: 11/18/2022] Open
Abstract
Carbapenem resistance in Gram-negative bacteria has come into sight as a serious global threat. Carbapenem-resistant Gram-negative pathogens and their main representatives Klebsiella pneumoniae, Acinetobacter baumannii, and Pseudomonas aeruginosa are ranked in the highest priority category for new treatments. The worrisome phenomenon of the recent years is the presence of difficult-to-treat resistance (DTR) and pandrug-resistant (PDR) Gram-negative bacteria, characterized as non-susceptible to all conventional antimicrobial agents. DTR and PDR Gram-negative infections are linked with high mortality and associated with nosocomial infections, mainly in critically ill and ICU patients. Therapeutic options for infections caused by DTR and PDR Gram-negative organisms are extremely limited and are based on case reports and series. Herein, the current available knowledge regarding treatment of DTR and PDR infections is discussed. A focal point of the review focuses on salvage treatment, synergistic combinations (double and triple combinations), as well as increased exposure regimen adapted to the MIC of the pathogen. The most available data regarding novel antimicrobials, including novel β-lactam-β-lactamase inhibitor combinations, cefiderocol, and eravacycline as potential agents against DTR and PDR Gram-negative strains in critically ill patients are thoroughly presented.
