Several reports have demonstrated that during a single plateletpheresis procedure, platelets may form heterotypic aggregates which may predispose certain donors to thrombotic complications. In this study, changes in the expression of neutrophil adhesion molecules (CD11b/CD18, CD50/54, CD62L) and platelet–neutrophil complex (PNC) formation were investigated by a flow cytometric method in healthy donors following a double dose plateletpheresis (DDP) procedure. Our results show that DDP which are carried out by the Fresenius AS.TEC 204 and Haemonetics MCS+ cause a significant increase in PNC formation in donors. Additionally, the Fresenius AS.TEC 204 device caused a decrease in CD62L expression which is a sign of mild neutrophil activation. Although the clinical significance of these laboratory changes is not clear, the occurrence of neutrophil activation and increased PNC formation might predispose certain donors to thrombotic complications following DDP.
