METHODS
Twenty-eight children were previously enrolled as part of a prospective, controlled, randomized study to assess rhG-CSF therapy in neonates with presumed sepsis.1 These newborn infants (26 to 40 weeks gestational age) with presumed bacterial sepsis within the first 3 days of life were random assigned to receive placebo or varying doses of rhG-CSF (1.0, 5.0, or 10.0 μg/kg every 24 hours or 5.0 or 10.0 μg/kg every 12 hours) for 3 days. Patients were enrolled in this
follow-up study after informed
Demographics
Families of infants who received rhG-CSF or placebo in the neonatal period were contacted for follow-up evaluation (median age 24.6 months, range 15.5 to 36 months). Twenty-one of 28 patients (18 boys) were available for evaluation. Mean chronologic age was 24.6 ± 1.7 months with a range of 15.5 to 36 months.
Hematologic screening
The hematologic profile of infants previously treated with rhG-CSF for presumed neonatal sepsis was evaluated by routine complete blood counts, manual differential, calculation of the
DISCUSSION
Treatment with rhG-CSF in adults and children with various congenital neutropenia syndromes or with acquired, chemotherapy-induced neutropenia results in a dose-dependent increase of the neutrophil count. Use of rhG-CSF has been generally well tolerated in children.4 Although therapeutic doses of rhG-CSF range from 2.5 to 10 μg/kg per day, doses of more than 100 μg/kg have been given without dose-limiting toxic effects.4
The delays in gross motor and perceptual/fine motor development seen were
