ABSTRACT
Administration of filgrastim (recombinant human granulocyte colony-stimulating factor [rhG-CSF]) (Neupogen) in healthy donors to mobilize hematopoietic stem cells (HSCs) is a widespread practice in adults. Application of peripheral blood stem cell (PBSC) collection in normal pediatric donors is scarce due to ethical issues. Hence, there are insufficient data on the long-term impact of PBSC procedure in healthy children. This retrospective study aimed to evaluate the early and late adverse effects of PBSC donation in pediatric donors. Bone marrow and PBSC procedures and known adverse events of each technique were completely explained to parents and when applicable to children and written informed consent was obtained. rhG-CSF was administered for 4 days. HSCs were collected on the fifth day through continuous-flow apheresis and donors were followed for 30 days. Manual chart review was performed to collect short-term complications. Donors' health status was assessed via a questionnaire. A total of 145 healthy pediatric donors with a median age of 10 years at the time of donation (2 to 15 years) were followed for a median of 4.8 years (range, 1.2 to 14.2 years). The most frequent symptoms of rhG-CSF administration were fatigue (5%) and headache (3%). Thirty-five (24%) donors experienced hypocalcaemia during apheresis procedure that quickly responded to treatment. Two pregnancies occurred after rhG-CSF administration that resulted in normal births. We did not encounter any serious adverse events, including neoplastic disorders and death in this study. rhG-CSF and leukophresis procedure were well-tolerated in this study and all children completed the donation process without interruption or reduction of rhG-CSF dosage. Our results suggest that rhG-CSF is a safe drug in healthy children for the purpose of HSC mobilization.
