Decreased levels of ferritin, mild thrombocytosis, and increased erythropoietin are sequential events among frequent plateletpheresis donors: Implication for a ferritin screen.

Background: It is generally recognized that repeat apheresis increases the risk for iron deficiency, thus may impact on the blood homeostasis. With regard to donor vigilance, we clarified the mid- to long-term effects of plateletapheresis by comparing the most frequent donors with the first-time ones in hematological and biochemical tests.

Methods: Levels of erythropoietin (EPO), hemoglobin (Hb) and ferritin were analyzed in double-unit (500 mL whole blood or 6 × 10 apheresis platelets) donations in three male cohorts, with identifiers of first-time whole-blood donors (n = 30), first-time platelet donors transited from maximal whole blood to apheresis (n = 30) and frequent donors subjected to extreme plateletpheresis (n = 90), respectively.

Evaluating the Effect of Inert Recruiting on Blood Donations Immediately After the Consecutive Earthquakes.

Objective: Disasters can have impact on the demand and supply of blood, with such a difficult perspective, planning of an appropriate response to counterbalance the need for blood is of paramount importance. The primary objective of this study was to evaluate how the impact of blood imbalances may be absorbed by inert recruitment of donors during 2 life-threatening earthquakes that shook Taiwan on the same date in 2016 and 2018.

Method: A retrospective database search from blood bank registries was developed.
