Fluconazole and levofloxacin prophylaxis are ineffective strategies for preventing infections in acute myeloid leukemia patients undergoing chemotherapy
Abstract
INTRODUCTION
Acute myeloid leukemia patients are at high risk for infections, which contribute to increased mortality rates of up to 70%. The use of antimicrobial prophylaxis has been shown to significantly lower rates of infection. Therefore, this retrospective study aimed to evaluate the effect of two agents that showed effective results in the literature, levofloxacin and fluconazole, as prophylaxis strategies in AML patients.
METHODOLOGY
A total of 85 AML patients' medical records treated with a 7+3 induction chemotherapy protocol in the Cancer Hospital of Uberlândia from 2017 to 2021 were screened and their data was collected. Within these patients, groups for analysis were created based on whether the acting physician included an antibacterial or antifungal prophylaxis protocol during induction. Contingency tables with χ² and odds ratio tests were realized to verify associations between prophylaxis and infection. Additionally, Kaplan-Meier curves with Cox regression were developed to analyze survival.
RESULTS
The use of prophylaxis with either fluconazole or levofloxacin did not lower rates of infection, as those who with prophylaxis did not demonstrate significant differences when compared to those without (20.3-29.7%, and 12.3-23.3%, respectively). Patients who suffered a bacterial infection during induction were shown to have lower overall survival, with a similar trend seen in fungal infections.
CONCLUSION
Bacterial and fungal infections were associated with higher…
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. Reported size: 85 participants or records.
