ABSTRACT
Background: Febrile neutropenia is a life-threatening condition commonly observed in patients with hematologic malignancies. The aim of this article is to provide updated knowledge about bloodstream infections in febrile neutropenia episodes within the Andean region of Latin America. Method: This retrospective study was based in 6 hospitals in Chile, Ecuador, and Peru and included adult patients with acute leukemia or lymphoma and febrile neutropenia between January 2019 and December 2020. Results: Of the 416 febrile neutropenia episodes, 38.7% had a bloodstream infection, 86% of which were caused by gram-negative rods, with Klebsiella pneumoniae, Escherichia coli, and Pseudomonas aeruginosa being the most frequently identified bacteria. K pneumoniae isolates were more frequently resistant than E coli to cefotaxime (65% vs 39.6%), piperacillin-tazobactam (56.7% vs 27.1%), and imipenem (35% vs 2.1%) and were more frequently multidrug resistant (61.7% vs 12.5%). Among P aeruginosa, 26.7% were resistant to ceftazidime, piperacillin-tazobactam, and imipenem, and 23.3% were multidrug resistant. Overall 30-day mortality was 19.8%, being higher with vs without a bloodstream infection (26.7% vs 15.3%, P = .005). Fever duration was also significantly longer, as well as periods of neutropenia and length of hospital stay for patients with bloodstream infection. Additionally, the 30-day mortality rate was higher for episodes with inappropriate vs appropriate empirical antibiotic therapy (41.2% vs 26.6%, P = .139). Conclusions: Considering the high rates of bacteria-resistant infection and 30-day mortality, it is imperative to establish strategies that reduce the frequency of bloodstream infections, increasing early identification of patients at higher risks of multidrug bacteria resistance, and updating existing empirical antibiotic recommendations.
ABSTRACT
La Red de Atención Primaria Metropolitana es una unidad ejecutora de ASSE del primer nivel de atención que brinda cobertura a 340.000 usuarios de Montevideo y zona metropolitana, a través de 14 Centros del Primer Nivel y 112 policlínicas. Se presenta como un espacio donde, no solo se cumplen actividades asistenciales de primer nivel, interdisciplinarias y complejas, sino como un espacio propicio para la adquisición, transferencia y perfeccionamiento de conocimientos, y para la investigación en salud. Esta investigación debe ser aplicada a las necesidades del primer nivel, detectadas conjuntamente por la comunidad y el equipo de salud a través de los Análisis de Situación de Salud (ASIS) correspondientes- Pero además debe ser de alta calidad ya que es la fuente natural para la optimización del proceso de gestión y de prestación de servicios de atención sanitaria.

Introduction: Febrile neutropenia (FN) is a common complication of patients undergoing chemotherapy (QMT). Clinical presentation is varied, from mild fever to severe sepsis with invasive bacterial infection (IBI) or invasive fungal infection (IFI), with great impact on prognosis and patient mortality. Patients and Methods: Prospective cohort study of FN episodes in adult patients with acute leukemia (AL) or lymphoma (L), diagnosed and treated at the Hospital Clínico Universidad Católica and Hospital Dr. Sótero del Río in Santiago from April 2010 to January 2012. Results: 130 patients were included with 105 episodes of NF, with an incidence of 0.65 per 100 days of observation, higher in AL than L (1.31 vs 0.25, p = 0.001). Etiology or clinical focus was documented in 67 (63.8%) episodes, with IBI in 33 (31.4%) and IFI in 21 (20%) cases. Mortality related to infection occurred in 4 (6.2%) patients. Conclusions: This study reports that the FN incidence and frequency of IBI and IFI during episodes are higher in AL vs. L. It is necessary to evaluate the impact of interventions to reduce its incidence, including the benefit and risk of using antibacterial and antifungal prophylaxis in high-risk subgroups.
Introducción: La neutropenia febril (NF) es una complicación frecuente de pacientes sometidos a quimioterapia (QMT). Su presentación clínica es amplia, desde cuadros leves a sepsis grave con infección bacteriana invasora (IBI) o infección fúngica invasora (IFI), con gran impacto en el pronóstico y mortalidad de los pacientes. Pacientes y Métodos: Estudio prospectivo de episodios de NF en cohorte de pacientes adultos con leucemia aguda (LA) o linfoma (L) diagnosticados y tratados en el Hospital Clínico Pontificia Universidad Católica de Chile y Hospital Dr. Sótero del Río en Santiago, desde abril de 2010 hasta enero de 2012. Resultados: Se reclutaron 130 pacientes que presentaron 105 episodios de NF, con incidencia de 0,65 por 100 días de observación, mayor en LA que en L (1,31 vs 0,25, p: 0,001), documentándose etiología o foco infeccioso en 67 (63,8%) de los episodios, con 33 (31,4%) IBI y 21 (20%) IFI. Hubo mortalidad relacionada a infección en 4 (6,2%) pacientes. Conclusiones: Se define la incidencia de NF (LA > L) y frecuencia de IBI e IFI durante el episodio (LA > L). Es necesario evaluar el impacto de intervenciones destinadas a disminuir la incidencia de NF, entre las que se debe incluir el beneficio y riesgo del uso sistemático de profilaxis antibacteriana y antifúngica en los subgrupos de mayor riesgo.
