title: [Aminoglycosides in patients with mucoviscidosis and pulmonary exacerbation. Comparison of once or three times daily administration].
abstract: Twenty-six patients with cystic fibrosis and pulmonary exacerbations were enrolled in a prospective randomized study to compare the efficacy of aminoglycosides (tobramycin or netilmicin) administered once daily (21 episodes, 5 with netilmicin, 16 with tobramycin) and thrice daily (23 episodes, 2 with netilmicin, 21 with tobramycin), respectively. In addition, the patients received an anti-pseudomonal beta-lactam antibiotic. In the single-dose group the total daily dosage was 4.97 +/- 1.12 mg/kg (total dosage per exacerbation: 74.55 mg/kg), compared to 9.60 +/- 2.70 mg/kg in the triple-dose group (total dosage per exacerbation: 165.12 mg/kg). The mean peak and trough serum levels of the aminoglycoside were 8.31 +/- 1.76 mg/l and 0.18 +/- 0.10 mg/l, respectively in the single dose group compared to 6.12 +/- 1.30 mg/l and 0.58 +/- 0.31 mg/l in the triple dose group. Success of treatment, defined as decrease in leucocyte counts, normalization of elevated CRP-values, number of days in hospital and interval until next admission to hospital, was not different between both groups. We conclude that single daily dose of aminoglycosides was as efficacious as triple dose in our patients.
