Isepamicin once daily plus ceftriaxone versus amikacin plus ceftriaxone in febrile neutropenic patients.
Isepamicin is a new aminoglycoside with in-vitro activity superior to amikacin. It is a poor substrate for the 6'-aminoacetyltransferase-I enzyme which inactivates amikacin and therefore organisms possessing this enzyme are not resistant to isepamicin. The aim of this study was to compare the efficacy and safety of co-administration of isepamicin once daily plus ceftriaxone to amikacin twice daily plus ceftriaxone to amikacin twice daily plus ceftriaxone in febrile neutropenic cancer patients. Febrile episodes in 235 patients (156 in isepamicin group and 79 in amikacin group) were treated in this study. They occurred in 218 different patients. Fifteen patients were enrolled twice and one three times. Response rates to the two treatment regimens for microbiologically documented episodes, clinically documented episodes and further unexplained fever were similar. Tolerance of the treatment regimens, as measured by serum creatinine levels, hypoaccousia and cutaneous allergy was also similar in both treatment groups. In conclusion, isepamicin given once daily when combined with ceftriaxone in the treatment of febrile episodes in neutropenic cancer patients was as effective and no more toxic than amikacin.
