ABSTRACT
To evaluate the hematopoietic stem/progenitor cell apheresis effect of Cobe Spectra (Version 6.1) and Fenwal CS 3000 Plus cell separators, fourty-two procedures on twenty donors using Cobe Spectra cell separator and twenty-two procedures on sixteen donors using Fenwal CS 3000 Plus cell separator were retrospectively analyzed. The number of CD34(+) cells collected, the collection efficiency (CE) of CD34(+) cells and the contaminations of red blood cell and platelet in the stem/progenitor cell products of two devices were compared. The results showed that there were no significant differences in the total number of CD34(+) cells collected and the CD34(+) cell CE between the two devices. There were positive correlations between the count of peripheral blood cells including leukocyte, monocyte, hematopoietic progenitor cell and CD34(+) cell after mobilization and the total number of CD34(+) cells collected. The stepwise multiple variable analyses revealed the peripheral blood stem/progenitor cell count emerged as the only significant independent predictive factor for CE. A negative correlation was seen between the peripheral blood monocyte count and the CD34(+) cell CE for the Fenwal CS 3000 Plus. The Fenwal CS 3000 Plus product contained more red blood cells than that of the Cobe Spectra. The decrease in the peripheral platelet count after Fenwal CS 3000 Plus apheresis was also greater. It is concluded that collection efficacy of Cobe Spectra (Version 6.1) and Fenwal CS 3000 Plus was similar. Cobe Spectra shall be used preferably to assure higher CD34(+) cell CE at a high peripheral blood monocyte count. The Cobe Spectra cell separator is better for the donors with mismatched blood type and the donors with thrombocytopenia.
