title: Prolonged ciprofloxacin administration does not accelerate neutrophil recovery after autologous bone marrow transplantation.
abstract: OBJECTIVE
  To determine whether prolonged ciprofloxacin administration following autologous bone marrow transplantation (ABMT) accelerates neutrophil recovery.
  
  
  METHODS
  Retrospective analysis of 40 consecutive patients undergoing ABMT.
  
  
  METHODS
  Tertiary care bone marrow transplant program.
  
  
  METHODS
  Two sequential arms of 20 consecutive patients with Hodgkin's disease or non-Hodgkin's lymphoma undergoing ABMT.
  
  
  METHODS
  The first arm received ciprofloxacin from the day of transplantation until initiation of broad-spectrum antibiotic therapy (median 5 days) while the second arm continued ciprofloxacin until recovery of the neutrophil count (median 15 days).
  
  
  RESULTS
  Neutrophil recovery was similar in the two groups (16 vs 14 days; p = 0.41). There were no differences in platelet recovery, bacteremia, or treatment-related mortality.
  
  
  CONCLUSIONS
  Prolonged ciprofloxacin administration does not significantly accelerate neutrophil recovery following ABMT.
