Donor age‐related differences in PBPC mobilization with rHuG–CSF

Abstract
BACKGROUND: Data on the administration of rHuG–CSF to normal donors 6 per kg of donor′s body weight in Group A and B, respectively. Fifty‐six percent of Group A donors needed only one apheresis to achieve ≥4 × 106 CD34+ cells per kg versus 39 percent of Group B donors (p = 0.01). Side effects were more common in Group B (71% vs. 41%; p<0.001). CONCLUSION: The administration of rHuG–CSF to donors <18 years old leads to CD34+ cell mobilization in a pattern similar to that observed in adults. Greater age was associated with a more frequent requirement for more than one apheresis to achieve a similar number of CD34+ cells.
