Objective:

To describe the demographic and clinical characteristics, as well as frequency and type of bacterial isolate and resistance patterns in patients with hematological neoplasms complicated by febrile neutropenia at San Ignacio University Hospital

Methods:

This is a retrospective observational study. Data were collected from medical records of adult patients admitted in the Hemato-oncology and Bone Marrow Transplant Unit. Inclusion criteria was presence of febrile neutropenia in the setting of a hematological neoplasm from January 2013 to December 2014.

Results:

345 episodes of febrile neutropenia from 193 patients were studied. An infectious focus was identified in 68.1% of episodes, and a bacterial isolate was obtained in 62.9% of episodes. The predominant microorganisms were gram-negative rods, gram-positive cocci, and fungi with a frequency of 63.7%, 27.9%, and 4.9% respectively. In term of resistance patterns, Escherichia coli and Klebsiella peumoniae isolates had a frequency of ESBL susceptibility pattern of 17.5% and 13.8% respectively; and a frequency of KPC susceptibility pattern of 1.25% and 2.8% respectively. The frequency of methicillin resistant Staphylococcus aureus was 6.8%. Death associated to infection ocurred in 16.5% of episodes.

Conclusions:

In patients with hematological neoplasms complicated by febrile neutropenia at San Ignacio University Hospital, we found a high rate of documentation of infectious focus, with a predominance of gram-negative rods, specially Enterobacteriacea; with a similar pattern in receptors of hematopoietic stem cell transplantation.
