Ceftriaxone kinetics after a single intravenous dose in leukemic children with fever and granulocytopenia.

Ceftriaxone (CFX) is a new third-generation cephalosporin with interesting characteristics as regards both its antibacterial spectrum and kinetics which make it potentially useful in the empiric treatment of infections in neutropenic cancer patients. However, since its kinetic characteristics in children with leukemia are not known and its pharmacokinetics are reported to be altered in such patients, we studied ceftriaxone's activity in ten leukemic children with fever and neutropenia. Our findings seem to be confirm the potential efficacy of the drug also in this particular type of patient.

Pharmacokinetics and bacteriological effect of ceftazidime in experimental Streptococcus pneumoniae, Haemophilus influenzae, and Escherichia coli meningitis.

The pharmacokinetics and bacteriological effect of ceftazidime were evaluated in rabbits experimentally infected with Streptococcus pneumoniae, Haemophilus influenzae type b, and Escherichia coli K1. The mean penetration of ceftazidime into cerebrospinal fluid after single-dose or constant-infusion administration ranged from 7.8 to 14.9%. The median cerebrospinal fluid bactericidal titers were 1:64 against S. pneumoniae and H. influenzae and 1:128 against E. coli. The bacterial colony counts in cerebrospinal fluid were reduced by 58% to 100% (-2.3 to -3.9 log10 CFU/ml) in 3 h and by 100% (-3.2 to -5.1 log10 CFU/ml) in 9 h of constant infusion, whereas in untreated infected animals, bacterial counts increased from +1.4 to +2.1 log10 CFU/ml in 9 h. These data on ceftazidime compare favorably with those on penicillin, chloramphenicol, netilmicin, and moxalactam in this experimental meningitis model.

Comparison of the concentrations of ceftazidime in the serum of newborn infants after intravenous and intramuscular administration.

The concentrations of ceftazidime in serum were studied in 16 preterm and term neonates to whom a single dose of 50 mg/kg had been administered intramuscularly or intravenously. After intramuscular injection, concentrations of ceftazidime in serum were comparable to those obtained with the intravenous dose, although they were more variable. Peak serum levels ranging from 50 to 102 micrograms/ml were reached 30 to 60 min after intramuscular injection. The concentrations declined monoexponentially after the peak, with a mean half-life of 3.8 +/- 1.1 h. Concentrations of ceftazidime in serum declined biexponentially after intravenous injection, with a terminal half-life of 4.7 +/- 1.5 h.

Control of antibiotic therapy in paediatric patients. II. Appropriateness of antibiotic choice in selected diseases.

The adequacy of antibiotic choice and the importance of the physician's knowledge of antibiotic use in causing errors in prescribing were investigated. A prospective three-month study was conducted in nine Italian pediatric hospital wards, involving every patient admitted to hospital for otitis, pneumonia or pharyngotonsillitis. The suspected aetiology and the antibiotic prescribed were recorded on a special form by the physician in charge. Each choice of antimicrobial agent was judged as adequate, justifiable or not justified. Out of 314 prescriptions 56.1% were assessed as adequate, 4.1% as justifiable and 39.8% as not justified. Analysis of the suspected bacteria, and of the correlation between the presumed aetiological agent and the prescribed antibiotic, demonstrates that inadequate knowledge of the physician plays a major role in producing a high percentage of unjustified prescriptions.

Control of antibiotic therapy in pediatric patients. I. A computer system to collect and analyze antibiotic prescriptions in hospitals.

A computer system to record and analyze antibiotic prescriptions in hospitalized children is described. This system is especially organized in order to obtain simultaneously a quantitative evaluation of antibiotic use and a qualitative analysis of the process by which the physician makes his decision for therapy. The practical employment of this program has been demonstrated by analyzing 765 prescriptions given in nine different pediatric hospital wards. Many errors of prescription have been demonstrated: antibiotic therapy was based on the clinical impression alone in 31.5% of the prescriptions, antibiotic choice was rational in 20.1% and the posology prescribed complied with the usually applied schemes in 22.4%. Finally, the physician's attitude regarding laboratory monitoring of side effects was adequate in 52.8% before treatment and 33.4% during antibiotic treatment.

[Amoxicillin-clavulanic acid combination in bacterial infections of the upper respiratory tract in childhood. Controlled clinical study].

A comparative clinical trial of amoxycillin - clavulanic acid combination versus erythromycin was carried out in a case series of 20 pediatric patients, suffering from upper respiratory tract infections with a proven bacterial etiology and different localization (tonsils, nasal and paranasal sinuses and ear). The results have confirmed the highly innovative efficacy of amoxycillin - clavulanic acid combination: the clinical judgement was in fact favourable, with eradication of the pathogenic agent in 90% of cases. The tolerability of the combination was globally good from both the general and local point of view.
