Prospective randomized clinical trial of teicoplanin for empiric combined antibiotic therapy in febrile, granulocytopenic acute leukemia patients.
The increasing prevalence of bacteremia caused by gram-positive bacteria in granulocytopenic acute leukemia patients prompted us to evaluate, in a prospective randomized trial, the role of teicoplanin, a new glycopeptide antibiotic, when it was added to amikacin plus ceftazidime, as an empiric therapy of fever in these patients. Of 47 evaluable episodes, 22 were treated with the teicoplanin regimen and 25 were treated with the combination of amikacin and ceftazidime. The overall response to therapy of patients treated with teicoplanin was slightly better (82% improvement) than that obtained with amikacin plus ceftazidime (52%). The response rate of patients with gram-positive bacteremias was 80% (4 of 5) to the regimen that included teicoplanin; 25% (1 of 4) of the patients treated with amikacin plus ceftazidime responded to treatment; and for patients with gram-negative bacteremias, the response rates were, respectively, 100% (4 of 4) and 70% (7 of 10). The better results obtained with amikacin-ceftazidime-teicoplanin treatment were most evident in patients with profound (less than 100/mm3) and persistent neutropenia (83 versus 30% improvement). Furthermore, a good response rate of patients with gram-positive bacteremias (seven of eight; 87% improvement) was achieved in a small group of bone marrow transplant patients who were all treated with amikacin-ceftazidime-teicoplanin. No severe side effects were documented in any patient. Teicoplanin, as a drug administered as a single daily dose, seems to be a safe and useful anti-gram-positive agent when used in combination with amikacin-ceftazidime as an empiric therapy of febrile episodes in granulocytopenic acute leukemia patients.
