Evaluation of the post-transfusion platelet increment and safety of riboflavin-based pathogen reduction technology (PRT) treated platelet products stored in platelet additive solution for 5 days or less versus 6-7 days.

Background And Objectives: Platelets are stored routinely for 5 days or less and extended platelet storage time could improve product availability. This study compared platelet count increments (CI24hs) of riboflavin plus UV-light (PRT) treated platelet products in platelet additive solution stored for 5 days or less to products stored for 6-7 days.

Material And Methods: This was a retrospective study comparing CI24hs between two groups.

Mobilization of hematopoietic progenitor cells from allogeneic healthy donors using a new biosimilar G-CSF (Zarzio®).

Peripheral blood progenitor cells (PBPCs) have become the major source of hematopoietic progenitor cells for allogeneic transplantation. In February 2008, Zarzio® was approved by the European Medicine Agency for PBPCs mobilization, but this authorization was not based in trials analyzing safety and efficacy for PBPCs mobilization. Since August 2011, Zarzio® has been used at our institution for PBPCs mobilization.
