ABSTRACT
Apheresis platelets are extensively utilized in clinical practice due to high purity and minimal side effects. These platelets are primarily obtained from regular blood donors. However, there is no consensus on whether plateletpheresis leads to iron deficiency among blood donors. In recent years, increasing attention has been given to the impact of plateletpheresis on the iron nutritional status of these donors. Numerous studies have indicated a prevalence of iron deficiency among plateletpheresis donors. The process of plateletpheresis involves the loss of red blood cells, which can accumulate over time and disrupt iron metabolism, ultimately resulting in iron deficiency anemia. This condition not only affects the physical well-being of the donors but also leads to a decline in their willingness to donate blood. Blood collection and supply institutions should enhance their focus on the iron nutritional status of plateletpheresis donors and implement various measures, such as intensifying health education regarding the significance of iron supplementation, implementing programs for testing iron deficiency, considering the provision of iron supplements and extending blood donation intervals. It is crucial to prevent iron deficiency in plateletpheresis donors. These institutions should explore calculation models that can predict personalized blood donation intervals and iron supplementation strategies, and seek a balanced approach that is optimal for maintaining adequate collections while safeguarding donor health. The article comprehensively reviews literature at home and abroad on the etiology and hazards of iron deficiency in plateletpheresis donors, as well as detection methods and response measures. It serves as a foundation for developing scientific and reasonable care measures for blood donation, while also achieving personalized and scientific management and recruitment strategies for blood donors.
ABSTRACT
【Objective】 To investigate the variation of hematological parameters in male plateletpheresis donors. 【Methods】 A total of 194 male plateletpheresis donors from Fujian Blood Center were divided into two groups according to the frequency of blood donation: Group 1 (n=107), with the number of plateletpheresis donation less than or equal to 12 per year; Group 2 (n=87), with the number of plateletpheresis donation more than 12 per year. Serum ferritin (SF) and related iron metabolism indexes, red blood cell count (RBC), hemoglobin (Hb), hematocrit(Hct), platelet count (Plt) and other blood routine indexes, as well as percentage of reticulocyte counts (RET%), immature reticulocyte fraction(IRF) and other reticulocyte indexes were measured before blood donation and analyzed by statistical methods. 【Results】 Compared with Group 2, the RBC, Hb, Hct, SF in Group 1 were significantly higher, while Plt, RET%and IRF were significantly lower(P<0.05), and the probability of ferritin decrease in Group 1 was lower, with significant difference(P<0.05). 【Conclusion】 As the number of donation increased, male plateletpheresis donors were prone to iron deficiency, and the bone marrow hematopoiesis were obviously enhanced. We should be more concerned about male plateletpheresis donors who donated more than 12 times per year, further more, SF monitoring should be conducted and the blood donation interval should be appropriately extended.
