[Retrospective survey of fluoroquinolone use in children].
BACKGROUND
Fluoroquinolones (FQ) are contraindicated in children because of the risk of cartilage damage.


METHODS
A retrospective survey concerning the use of FQ in children during the first 6 months of 1993 was organized in 1994. One hundred and sixty-seven Heads of pediatric departments were questioned.


RESULTS
One hundred and fifty (90%) of those surveyed responded: 62 (41.3%) were FQ prescribers, 83 (55.3%) were non prescribers and five (3.4%) were not able to answer. Among the 62 prescribers of FQ, 17 departments (27%) were not able to indicate the number of prescriptions and 45 departments (73%) reported one to 75 prescriptions during the study period. Twenty-one departments out of the 45 were not able to identify the children treated with FQ. We obtained a group of 104 children aged 9.0 +/- 5.0 years (mean +/- standard deviation [SD]), treated with 165 courses of FQ during 20 +/- 45 days (1-535 days) with concomitant treatments for 132/165 courses (80%). Fifty children (48%) were suffering from cystic fibrosis, 37 children (36%) were not, and, in 17, the diagnosis was not determined (16%). The FQ treatment administered either orally (73%) or intravenously (26%) was ciprofloxacin in 69% of the courses with a 25.1 +/- 7.0 mg/kg/day oral dose (mean +/- SD dose), and a 23.5 +/- 11.4 mg/kg/day intravenous dose, pefloxacin in 23 courses/165 (14%) with a 17.2 +/- 3.8 mg/kg/day dose, ofloxacin in 15 courses/165 (9%) with a 21.0 +/- 11.9 mg/kg/day dose, norfloxacin in 13 courses/165 (8%) with a 25.6 +/- 7.5 mg/kg/day dose. Twenty-one adverse events were reported in 17 children (16%) (11 of them with cystic fibrosis). These were cutaneous events (photosensitivity, cutaneous eruption) in eight courses, rheumatologic events (arthralgia, arthritis) in seven courses and gastrointestinal events (nausea, vomiting, diarrhea) in three courses.


CONCLUSIONS
This survey shows that FQ are prescribed in children although their use is not approved in this age group and that numerous side effects have been recorded. The absence of exhaustive information (due to the retrospective nature of the survey) and the difficulties in interpreting the side effects for which validity and causal assessment have not been worked out according to a standardized method and in the absence of a control group stress the need for a prospective study.
