The role of colonization with resistant Gram negative bacteria in the treatment of febrile neutropenia after stem cell transplantation.
Introduction: Febrile neutropenia (FN) is one of the most common complications of stem cell transplantation. The aim of this analysis was to evaluate the frequency of sepsis in patients with FN colonized with resistant Gram negative bacteria (Extended spectrum β-lactamase positive, multidrug resistant (MDR) P. aeruginosa) and the choice of primary antibiotic in colonized patients.
Patients and methods: This was a retrospective study analyzed data from patients who underwent hematopoietic stem cell transplantation from 01/2018 to 09/2022. Data were extracted from the hospital information system.
Results: Carbapenem as the primary antibiotic of choice was chosen in 10.9% of non-colonized +/-AmpC patients, 31.5% of ESBL+ patients, and 0% of MDR P. aeruginosa patients. Patients with FN and MDR P. aeruginosa colonization had a high prevalence of sepsis (namely 100%, p = 0.0197). The spectrum of sepsis appeared to be different, with Gram negative bacilli predominating in the ESBL+ group (p = 0.0123, OR 5.39 [95% CI 1.55-18.76]). Colonizer sepsis was present in 100% of sepsis with MDR P. aeruginosa colonization (p=0.002), all in allogeneic transplantation (p=0.0003), with a mortality rate of 33.3% (p=0.0384). The incidence of sepsis in patients with ESBL+ colonization was 25.9% (p=0.0197), with colonizer sepsis in 50% of sepsis cases (p=0.0002), most in allogeneic transplantation (p=0.0003).
Conclusion: The results show a significant risk of sepsis in FN with MDR P. aeruginosa colonization, this state is almost exclusively caused by the colonizer. At the same time, a higher risk of Gram negative sepsis has been demonstrated in patients colonized with ESBL+ bacteria.
期刊介绍:
The Journal of Hospital Infection is the editorially independent scientific publication of the Healthcare Infection Society. The aim of the Journal is to publish high quality research and information relating to infection prevention and control that is relevant to an international audience.
The Journal welcomes submissions that relate to all aspects of infection prevention and control in healthcare settings. This includes submissions that:
provide new insight into the epidemiology, surveillance, or prevention and control of healthcare-associated infections and antimicrobial resistance in healthcare settings;
provide new insight into cleaning, disinfection and decontamination;
provide new insight into the design of healthcare premises;
describe novel aspects of outbreaks of infection;
throw light on techniques for effective antimicrobial stewardship;
describe novel techniques (laboratory-based or point of care) for the detection of infection or antimicrobial resistance in the healthcare setting, particularly if these can be used to facilitate infection prevention and control;
improve understanding of the motivations of safe healthcare behaviour, or describe techniques for achieving behavioural and cultural change;
improve understanding of the use of IT systems in infection surveillance and prevention and control.
