Abstract:
BACKGROUND: Use of single donor apheresis platelets and concerning for the quality of apheresis platelets has been rapidly increased. Apheresis platelets depleted white blood cell(WBC) are used to prevent or to reduce febrile non-hemolytic transfusion reactions, alloimmunization and cytomegalovirus infection. We compared COBE Spectra LRS (leukoreduction system) and COBE Spectra with PALL PXL 8 in terms of the yield predictors, processing times, and WBC contamination. METHOD: Seventy-two single donors who visited Apheresis Unit(APU) in St. Mary s hospital were prospectively randomized into COBE Spectra LRS and COBE Spectra followed by PALL PXL 8 between September 1997 and October 1998. We used Coulter counting for platelet and Nageotte hemocytometer for WBC count. Data were analyzed by independent t-test. RESULTS: The mean platelet yield per unit was 3.6+ 1.0 x 10 ' with COBE spectra LRS compared to 2.9+ 1.1 X 10 with COBE Spectra(p=0.002), and the mean WBC content per unit with COBE spectra LRS was 4.1 x 104(0.4-23.5) compared to 3.7 x 104(0.43-17.9) with PALL PXL""8(p=0.0728). CONCLUSIONS: This study shows that COBE Spectra LRS has higher platelet yields than that of COBE Spectra, and similar WBC contamination compared to PALL PXL 8. Therefore, this data suggests that COBE Spectra LRS is conveient than COBE Spectra with PALL PXL 8 in clinical practice. (Korean J Blood Transfusion 10(1): 43-51, 1999)
