Efficiency of Antibacterial Prophylaxis in Azacitidine Treated Patients (AZABAC)

Efficiency of Antibacterial Prophylaxis (Levofloxacin) in Azacitidine Treated Patients

Infections are a major life-threatening complication in patients with myelodysplastic syndrome (MDS) or acute myeloid leukaemia (AML). Currently there is no guidelines about antibacterial prophylaxis to prevent infections in patients with myelodysplastic syndrome or acute myeloid leukaemia. The investigators will conduct a randomized prospective study to evaluate the benefit of prophylactic antibacterial by levofloxacin on febrile episode in Azacytidine treated patients (MDS and AML).

Study Overview

• Status: Completed
• Conditions: Acute Myeloid Leukemia; Myelodysplastic Syndromes
• Intervention / Treatment: Drug: Levofloxacin

Detailed Description

This is a randomized prospective study with 2 arms to evaluate the efficacy of Levofloxacin prophylaxis in Azacytidine treated patients (MDS and AML) Levofloxacin will be given 500mg/d p.o. for the first three cycles of Azacytidine in patients randomized in arm antibacterial prophylaxis. In control arm patients will not received levofloxacin.

The expected duration of subject participation is one year after randomization.
