Chemoprophylaxis of bacterial infections in granulocytopenic patients with ciprofloxacin vs ciprofloxacin plus amoxicillin.

Ciprofloxacin was compared to ciprofloxacin plus amoxicillin as antibacterial prophylaxis in 53 evaluable patients with neutropenic episodes, because an oral penicillin may help to decrease the incidence of gram-positive infections. The two groups were randomized and evaluated in a number of febrile episodes, in days at fever/at risk, in mean interval of first febrile episode, in duration of antibiotic therapy and in causative organisms in febrile episodes. In conclusion, no significant difference was observed between the two groups in prevention of gram-positive bacteremias.
