Objective:

to describe the demographic, clinical, therapeutic and microbiological characteristics of patients with hematological malignancies undergoing chemotherapy who develop febrile neutropenia during treatment, as well as the mortality at discharge.

Methods:

a retrospective cohort study of patients with hematologic neoplasms who developed febrile neutropenia and were seen at the Hospital Universitario San Vicente Fundación in Medellín.

Results:

records of 110 episodes of febrile neutropenia were obtained. The mean age was 45 years. In 55.4%, a microbiological diagnosis was obtained; bacteremia was documented in 83.8% of these. The most common microorganisms wereK.pneumoniae(30%) andE. coli(18%). Antibiotic resistance due to ESBLs or carbapenemases ingram negativebacilli was 33%. Death occurred in 17% of patients. Acute lymphocytic leukemia (ALL) and acute myeloid leukemia (AML) were the most prevalent underlying diagnoses; the most prevalent clinical focus was bacteremia (24.5%).

Conclusion:

in our case series, there are significant differences in the percentage of patients with bacteremia, as well as in global mortality, compared to the rest of the cohorts in the region. A new research study needs to be carried out to clarify the source of these differences.(Acta Med Colomb 2020; 45. DOI:https://doi.org/10.36104/amc.2020.1386).
