Randomized double blind trial of ciprofloxacin prophylaxis during induction treatment in childhood acute lymphoblastic leukemia in the WK-ALL protocol in Indonesia. OBJECTIVES: Toxic death is a big problem in the treatment of childhood acute lymphoblastic leukemia (ALL), especially in low-income countries. Studies of ciprofloxacin as single agent prophylaxis vary widely in success rate. We conducted a double-blind, randomized study to test the effects of ciprofloxacin monotherapy as prophylaxis for sepsis and death in induction treatment of the Indonesian childhood ALL protocol. METHODS: Patients were randomized to the ciprofloxacin arm (n = 58) and to the placebo arm (n = 52). Oral ciprofloxacin monotherapy or oral placebo was administered twice a day. All events during induction were recorded: toxic death, abandonment, resistant disease, and complete remission rate. RESULTS: Of 110 patients enrolled in this study, 79 (71.8%) achieved CR. In comparison to the placebo arm, the ciprofloxacin arm had lower nadir of absolute neutrophil count during induction with median of 62 (range: 5-884) versus 270 (range: 14-25,480) × 10(9) cells/L (P < 0.01), greater risks for experiencing fever (50.0% versus 32.7%, P = 0.07), clinical sepsis (50.0% versus 38.5%, P = 0.22), and death (18.9% versus 5.8%, P = 0.05). CONCLUSION: In our setting, a reduced intensity protocol in a low-income situation, the data warn against using ciprofloxacin prophylaxis during induction treatment. A lower nadir of neutrophil count and higher mortality were found in the ciprofloxacin group.
