title: [Chemoprophylaxis of bacterial infections in granulocytopenic patients with new quinolone: a comparison of trimethoprim-sulfamethoxazole (ST) alone with ST plus ciprofloxacin].
abstract: Fifty-three granulocytopenic patients were studied in a randomized trial comparing trimethoprim-sulfamethoxaxole (ST) alone with ST + ciprofloxacin (CPFX) for prevention of bacterial infections. Seventeen febrile episodes occurred in 24 patients receiving ST alone, and 9 febrile episodes occurred in 29 patients receiving ST + CPFX. ST + CPFX was significantly effective than ST alone (p < 0.005). Although ST alone was effective to prevent infections in moderately granulocytopenic patients, it could not prevent infections in severely granulocytopenic patients whose minimal granulocyte count was less than 250/microliters during prophylactic treatment. In contrast, ST + CPFX was effective in severely as well as in moderately granulocytopenic patients. Clinically significant adverse reactions were not observed in both regimens. These results suggest that combination with ST and CPFX is more efficacious than ST alone for the prevention of bacterial infections in granulocytopenic patients.
