Title: Collection of peripheral hematopoietic stem/progenitor cells
Author: V. Rimajova Dihenescikova, M. Mistrik, J. Martinka, M. Zwiewka, I. Bizikova, A. Batorova


Objectives: Several variables possibly affecting collection of peripheral hematopoietic stem/progenitor cells (PBSC) were evaluated: type of apheresis machine (Amicus version 2.5, Baxter vs Cobe Spectra version 7.0, Terumo BCT), venous access (peripheral vein vs central venous catheter, i.g. CVC), and apheresis regimen (standard vs large volume leukapheresis, i.g. SVL vs LVL) with the objective to increase collection efficacy at the site.
Background: Peripheral blood represents the currently preferred source of hematopoietic stem/progenitor cells (HSCs) for transplantation.
Methods: Data regarding 169 collection procedures performed in healthy donors and patients between January 2008 and December 2011 at the Clinics of Haematology and Transfusiology in St Cyril and Method Hospital in Bratislava (Slovakia) were analysed.

Results: With Cobe Spectra apheresis machine it was possible to process larger blood volumes per procedure with higher CD34+ cell collection efficiency (p = 0.0229) and lower RBC contamination of the harvest than with Amicus (p = 0.0116).

On the other hand, Amicus helped to limit PLT contamination of the harvest (p < 0.0001), thus minimizing post-procedural decrease in patient´s PLT count. The highest detected advantage of CVC usage was higher flow rate of procedure, thus processing larger blood volumes per unit of time. Interesting finding was the tendency to lower harvest PLT contamination (p = 0.054).

When LVL was performed, significantly higher HSCs yields were collected, even in “poor mobilizers” when the pre-run parameters were low.
Conclusion: Management of PBSC collection requires a particular approach in each subject. Institutionally and individually optimized collection may help to improve the transplantation outcome and decrease the financial costs (Tab. 8, Ref. 15).

Keywords: peripheral hematopoietic stem/progenitor cells, apheresis collection, central venous catheter.
