[Short-term effects of hemogram in healthy donors after peripheral blood stem cell collection].
2015
To observe the short- term effects of hemogram in donors after peripheral blood stem cell(PBSC)collection and donors' tolerance.A total of 166 related allogeneic donors were selected from The First Affiliated Hospital of Medical School of Zhejiang University between January 2013 and December 2014, including 86 male and 80 female. All donors accepted granulocytecolony- stimulating factor(G-CSF)5-10 μg·kg⁻¹·d⁻¹ until collection finished and were measured by blood cells count before and after PBSC collection.After PBSC collection, the hemoglobin level decreased from 145(94-181)g/L to 138(93-167)g/L, and the platelet counts decreased in all donors from 231(105- 490)× 10⁹/L to 95(39- 210)× 10⁹/L. The amount of hemoglobin contamination in collection products was weak correlated with the decreased hemoglobin in peripheral blood(r=0.297, P=0.017), and the platelet contamination was high correlated with that decreased in peripheral blood(r=0.719, P 0.05). In addition, the decline of hemoglobin level after once and twice PBSC collection was of a significant difference between four groups in different body mass index(BMI)(P=0.003 and P 0.05).The hemoglobin level decreased mildly in healthy allogeneic hematopoietic stem cell donors after PBSC collection and it is better to adjust parameters every time to ensure their safety for thinner donors. However, it will increase the risk of platelet decline, which is unrelated with ages and BMI and can be tolerated.
