Levofloxacin prophylaxis in neutropenic patients
Abstract
Fluorquinolone-prophylaxis has proven useful in preventing infections in high risk neutropenic patients. The objective of this study was to describe the clinical, microbiological and therapeutic characteristics, and outcome of patients in the first episode of febrile neutropenia, comparing those who received levofloxacin prophylaxis with those who didn't. It was a prospective observational study that included all the episodes of inpatients with febrile neutropenia (February 1997- November 2014), also including the first episode in a same patient in different hospitalizations. Of 946 episodes here included, 821 presented high risk febrile neutropenia. A total of 264 cases (27.9%) received levofloxacin prophylaxis. This group consisted of a higher proportion of high risk febrile neutropenia (99.2% vs. 82.3%, p = 0.0001) and patients that had received an hematopoietic stem cell transplant (67.8% vs. 29.3%, p = 0.0001) compared to those who didn't receive prophylaxis. Those who received levofloxacin prophylaxis presented a similar frequency of clinically diagnosed but a lower proportion of microbiologically documented infections (28.8% vs. 37.5%, p = 0.012) than those who didn't receive prophylaxis. The episodes of bacteremia that occurred in the first group were more frequently caused by multidrug resistant bacteria (MDRB) (34.5% vs. 17.3%, p = 0.007) and by extended spectrum beta lactamase producing Enterobacteriaceae (19% vs. 3.8%, p = 0.0001). The group that received…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence.
