Background: Polyoma BK virus (BKV) is associated with hemorrhagic cystitis during hematopoietic stem cell transplantation (HSCT). The objective of this study was to test whether standard-dose ciprofloxacin might suppress reactivation of BKV infection during HSCT.
Methods: Sixty-eight patients received ciprofloxacin or a cephalosporin as antibiotic prophylaxis after undergoing allogeneic HSCT.
