inline extracorporeal photopheresis evaluation of cell collection efficiency

xtracorporeal photopheresis (ECP) therapy has proved to be an effective and safe treatment for graft‐versus‐host‐disease (GvHD), an important complication after hematopoietic stem cell transplantation. In 2016, we acquired Therakos CellEx, a dedicated inline ECP device to accomplish a significant increase in ECP activity. In literature, we found few data reporting CellEx performance evaluated in terms of collection efficiency to qualify the device. Hence, we decided to collect and analyze our data in order to build a reference in terms of expected results of the procedure. Here we report our data of ECP performed using CellEx in a 12‐month period focusing on collection efficiency assessment, as well as procedural and apheretic product characteristics
