Highly expressed in almost all myeloma cells, CD38 is an attractive treatment target.
Anti-CD38 monoclonal antibodies have been approved for first-line treatment in non-transplantable multiple myeloma (MM) patients.
However, it has been found in clinical use that anti-CD38 monoclonal antibodies bind to CD38 on red blood cells (RBCs) and cause panagglutination in indirect antiglobulin test (IAT), resulting in false positives of IAT (Transfusion, 55, 2015 and 1545; Transfusion, 55, 2015 and 1555).
Thereby, interfering with blood bank testing and leading to the delay of further diagnosis and treatment.
With more and more patients receiving anti-CD38 treatment, it is of great importance to recognize this problem and optimize relevant diagnosis and treatment procedures to prevent RBC transfusion delays and reduce laboratory costs.
CD38 在几乎所有骨髓瘤细胞中高表达,是一种有吸引力的治疗靶点。
抗 CD38 单克隆抗体已被批准用于不可移植多发性骨髓瘤 (MM) 患者的一线治疗。
然而,在临床应用中发现,抗 CD38 单克隆抗体与红细胞 (RBC) 上的 CD38 结合,并在间接抗球蛋白试验 (IAT) 中引起全凝集,导致 IAT 假阳性 (Transfusion, 55, 2015 and 1545; Transfusion, 55, 2015 and 1555)。
从而干扰了血库检测,并导致进一步诊断和治疗的延迟。
随着越来越多的患者接受抗 CD38 治疗,认识到这一问题并优化相关诊断和治疗程序以防止红细胞输注延迟和降低实验室成本非常重要。
