Prevention of bacterial and fungal infections in acute leukemia patients: a new and potent combination of oral norfloxacin and amphotericin B.
The effect of a combination regimen using norfloxacin (NFLX) and amphotericin B (AMPH-B) for prevention of infections in patients with acute leukemia being treated by remission-induction chemotherapy in a randomized, controlled trial was studied. One hundred and six consecutive, evaluable patients were randomly assigned to receive orally 200 mg of norfloxacin two or four times daily and 200 mg of amphotericin B four times daily, or amphotericin B only. A smaller percentage of patients with bacteriologically-documented infections was observed in the study group compared with the control group (34.6% vs 56.9%; P < 0.05). The mean number of days that the patients received empirical antibiotic therapy was shorter in the study group (23 days vs 30 days; P < 0.05). The percentage of patients with a gram-negative bacterial infection (9.6% vs 27.5%; P < 0.05) or a fungal infection (17.3% vs 37.3%; P < 0.05) was decreased in the study group. This new combination antimicrobial regimen is safe and effective for prevention of gram-negative bacterial as well as fungal infections in patients with acute leukemia being treated with cytotoxic remission-induction chemotherapy.
