在围移植期清除血液中的抗A/B抗体有助于ABO血型不合移植,并显著增加供体库。我们一直在开发与全血灌注兼容的抗A/B免疫吸附装置(BSAF)。BSAF基于集成的微滤中空纤维,其中抗体捕获珠均匀分布在纤维间隙空间内。在这项研究中,我们制造了BSAF原型,从概念性临床规模设备适当缩小。然后,我们首次测量了通过缩小的BSAF装置再循环的血液样本中抗A捕获的时间过程。我们观察到IgM(96% ± 5%,n = 5,p< 0.001)和IgG(81% ± 18%,n = 5,p< 0.05)抗A抗体滴度在2 h内显著降低。在5次实验中,我们未观察到红细胞压积、总血浆蛋白浓度、血浆游离血红蛋白浓度和抗B抗体滴度的初始值和最终值之间的显著变化。总之,我们表明BSAF模块在简单的一步过程中选择性地从血液中去除抗A抗体,而不需要单独的血浆置换装置。© 2012 Wiley Periodicals,Inc.

Anti‐A/B antibody removal from blood in the peritransplantation period facilitates ABO‐incompatible transplantation and significantly increases the donor pool. We have been developing an anti‐A/B immunoadsorption device (BSAF), compatible with whole blood perfusion. The BSAF is based on integrated microfiltration hollow fibers with antibody capturing beads uniformly distributed within the fiber interstitial space. In this study we fabricated BSAF prototypes, appropriately scaled down from a conceptual clinical scale device. We then, for the first time, measured the time course of anti‐A capture from blood samples recirculating through the scaled down BSAF devices. We observed a significant reduction in IgM (96% ± 5%,n= 5,p< 0.001), and IgG (81% ± 18%,n= 5,p< 0.05) anti‐A antibody titers within 2 h. We did not observe a significant change between the initial and final values of hematocrit, total plasma protein concentration, plasma free hemoglobin concentration, and anti‐B antibody titer over five experiments. In conclusion we showed that the BSAF modules selectively removed anti‐A antibodies from blood in a simple one step process, without requiring a separate plasmapheresis unit. © 2012 Wiley Periodicals, Inc.
