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
Listeriosis infection is a severe disease, with high morbidity and mortality in the immunocompromised patient, especially with disseminated and fatal presentations in cancer patients. A descriptive study was developed to describe the clinical and epidemiologic characteristics in oncologic patients with listeriosis in the Instituto Nacional de Enfermedades Neoplásicas between the years 2005-2015. A total of 29 patients were included; 23 (79.3%) of the listeriosis cases showed up in patients with hematological neoplasia, of which 52.1% was acute lymphatic leukemia and 39.1% non-Hodgkin's lymphoma. The 72.4% of the isolated species correspond to Listeria monocytogenes. Twenty-seven (93.1%) patients met sepsis criteria and twenty-four (82.7%) had neurologic affection. Bacteremia was the most common presentation, followed by meningoencephalitis (20.6%). Global mortality was 75.8%. In conclusion in cancer patients, listeriosis implies high morbidity and mortality. Therefore, the suspicion of this entity is mandatory in onco-hematologic patients with sepsis and acute neurologic symptoms.
La listeriosis es una infección severa de elevada morbimortalidad en el paciente inmunocomprometido, existen formas diseminadas y fatales en el paciente oncológico. Se realizó un estudio descriptivo de las características clínico-epidemiológicas de los pacientes oncológicos con listeriosis atendidos en el Instituto Nacional de Enfermedades Neoplásicas entre 2005 y 2015. Se incluyeron 29 pacientes, 23 (79,3%) casos de listeriosis se presentaron en pacientes con neoplasia hematológica, de los cuales el 52,3% fueron leucemia linfática aguda y 39,1% linfoma no Hodgkin. Listeria monocytogenes representó el 72,4% de las especies aisladas. Veintisiete (93,1%) tuvieron criterios de sepsis y veinticuatro (82,7%) compromiso neurológico al ingreso. La presentación más común fue la bacteriemia, seguida de la meningoencefalitis (20,6%). La mortalidad global fue del 75,8%. Se concluye que la listeriosis conlleva elevada morbimortalidad en el paciente oncohematológico, por lo que debe sospecharse en el paciente admitido con sepsis y/o compromiso neurológico agudo.
