Objective: In this study, we aimed to investigate the distribution of microorganisms isolated from febrile neutropenic patients in the adult hematology clinic and their antimicrobial susceptibilities for six years.


Methods: The results of culture samples taken during 598 febrile episodes of 556 neutropenic patients admitted to the adult hematology clinic between January 2010 and December 2015 were retrospectively evaluated. Bactec™ 9120 (Becton Dickinson, Sparks, MD, USA) automated system for blood cultures from patients. Conventional diagnostic methods for identification and antibiogram, and VITEK® 2 (bioMérieux, Marcy l'Etoile, France) automated system was used if necessary.


Results: During the six-year study period, 556 neutropenic patients were evaluated in 299 (53.7%) male patients. As the underlying diseases, 233 (42%) acute myeloid leukemia, 122 (22%) acute lymphoblastic leukemia, and 112 (20%) lymphoma were mostly seen. Gram-negative bacteria were the most frequent cause and their distribution were Escherichia coli, Klebsiella, Acinetobacter and Pseudomonas in order of frequency. Extended-spectrum β-lactamase positivity in E. coli was 51%, while in Klebsiella spp. it was 55%. Coagulase-negative staphylococci (21%), E. coli (19%) and Klebsiella spp. (16%) were the most frequently isolated microorganisms. Enterococci were the most frequently isolated Gram-positive bacteria in 2012, exceptionally.


Conclusions: In febrile neutropenia, a problem with frequent occurrence and fatality potential, we should closely monitor the resistance surveillance in organisms isolated, and review the antibacterial drugs frequently used for success of empirical therapy protocols.
