We intended to answer two questions: (1) Does storage time of platelet concentrates (PCs) influence the efficacy of leucocyte depletion by filtration? (2) Does pre-storage leucocyte depletion by filtration of PCs improve the post-storage quality? To this end we tested in parallel the halves of 10 double-sized PCs, one half stored after filtration through a polyester filter (PL 50, Pall), the other half filtered after a 5-day storage period. Efficacy of leucocyte depletion showed to be independent of the age of PCs, and pre-storage leucocyte depletion of PCs was not able to improve the quality of PCs stored for 5 days, as long as the leucocyte contamination of unfiltered PCs was lower than 0.5 x 10(8)/unit.
(1)血小板浓缩物(PCs)的储存时间是否会影响过滤去除白细胞的效果?(2)对PCs进行储存前过滤去除白细胞是否能改善储存后的质量?为此,我们对10个双倍量的PCs进行了平行测试,一半在通过聚酯过滤器(PL 50,颇尔公司)过滤后储存,另一半在储存5天后进行过滤。结果表明,去除白细胞的效果与PCs的储存时间无关,并且只要未过滤的PCs中的白细胞污染低于0.5×10⁸/单位,对PCs进行储存前过滤去除白细胞并不能改善储存5天的PCs的质量。
