Removal of serological interference in the treatment of multiple myeloma with CD38 monoclonal antibody using polybrene method / 中国输血杂志

ABSTRACT

【Objective】 To investigate the clinical feasibility of polybrene method to remove serological interference in patients receiving anti-CD38 monoclonal antibody for the treatment of multiple myeloma, and its detection performance of alloantibodies. 【Methods】 For patients receiving anti-CD38 monoclonal antibody for the treatment of multiple myeloma, unexpected antibody screening and cross-matching blood test were performed by polybrene method. 【Results】 The polybrene method can remove the interference of anti-CD38 monoclonal antibodies on blood group serology; both methods can effectively remove anti-CD38 monoclonal antibody to detect anti-E, anti-D, anti-Fya and anti-S antibodies.The titers of anti-D, anti-E, anti-Fya and anti-S alloantibodies, yielded by enhanced polybrene method, were higher than those of the polybrene method.Seven patients received K-antigen-negative blood transfusion without any adverse reactions to blood transfusion. 【Conclusion】 For the treatment of multiple myeloma using CD38 monoclonal antibody, the polybrene method can quickly and effectively remove the interference of daratumumab with blood group serology.
