Therapeutic drug monitoring of aminoglycosides in acute myeloid leukaemia patients.

Abstract

International guidelines limit the use of aminoglycosides in febrile neutropenia to severe situations. We retrospectively reviewed the use of aminoglycosides in adult acute myeloid leukaemia patients admitted in 2009. Our guidelines include precise indications (severe sepsis, shock, drug resistance), dosing regimens (once-daily 20 mg/kg/day amikacin, 5 mg/kg/day gentamicin), durations of treatment, drug monitoring timing, and target C(max) concentrations (40 mg/l amikacin, 20 mg/l gentamicin). Thirty-one patients received 46 aminoglycoside courses: 31 amikacin and 15 gentamicin. The mean prescribed dosage was 19 ± 2.8 mg/kg/day for amikacin and 4.7 ± 0.9 mg/kg/day for gentamicin. The mean duration of use was 2.9 days for both drugs. The mean C(max) for amikacin was 47 ± 13 mg/l and for gentamicin was 13.6 ± 7.5 mg/l. In compliant regimens, all amikacin patients and a third of gentamicin patients had adequate C(max). Among 23 isolated pathogens, 65.5% were susceptible to both drugs and 11.5% to amikacin only. This vindicates the 20 mg/kg/day amikacin dosage and suggests a need to increase the gentamicin dosage.
