Akut Myeloid Lösemi Hastaları İçin Kinolon Profilaksisinde Levofloksasin ve Moksifloksasin Kullanımının Prospektif Değerlendirmesi.

Objective: The study aimed to evaluate the clinical effects of levofloxacin (LEVO) and moxifloxacin (MOXI) prophylaxis during the treatment of acute myeloid leukemia (AML). Methods: This study had a prospective observational design and included AML patients who were scheduled for standard remission-induction (RI) or consolidation (C) chemotherapy. Prophylactic LEVO or MOXI was started at a ratio of 1:1 when neutropenia developed, and two groups were created. The primary endpoint was the frequency of febrile neutropenia (FN) and the time to FN. Results: 120 patients (60 patients in each group) were enrolled in the study. The frequency of FN tended to be higher in the LEVO group but was statistically insignificant (82.1% vs. 75.5%; p=0.702). The time to FN was 10.8±5.7 days and 10.1±5.7 days in the LEVO and MOXI groups, respectively (p=0.393). Microorganisms were izolated in 50.8% of patients who developed FN. The documented infection and bacteremia rate tended to be higher in the MOXI group (71.1% vs. 56.6%; p=0.331 and 87.5% vs. 80.5%; p=0.906). The rates of quinolone resistance were 69.2% and 75% in the LEVO and MOXI groups, respectively (p=0.451). The frequency of FN was higher during the RI phase than the C phase (89.1% vs. 70%; p=0.010). The frequency of documented infection was higher during the C phase than during the RI phase (77.1% vs. 49.1%; p=0.008). Conclusion: This study showed that prophylactic MOXI and LEVO have similar efficacy in AML patients. [ABSTRACT FROM AUTHOR]
