摘要
抗体介导排斥反应(AMR)已经成为导致移植物丢失的主要原因。C4d在管周毛细血管(PTC)部位沉积是肾移植体液免疫活跃的标志,单纯C4d阳性不能确诊为AMR,当临床上出现循环供者特异性抗体(DSA)、病理特征和/或移植肾功能不全时必须考虑AMR。C4d和DSA检测阳性与移植物存活率下降密切相关,特别是在检测时就出现移植物功能不全者。本文主要围绕C4d和DSA检测在肾移植AMR中的应用研究作一综述。
Antibody-mediated rejection( AMR) has become a main reason in graft loss. The detection of C4 d deposition in peritubular capillarie( PTC) is a valuable marker of humoral activity in the renal allograft. C4 d positivity alone is nondiagnostic for antibody-mediated rejection. Presence of circulating HLA donor-specific antibody( DSA),histologic features,and/or graft dysfunction must be considered in the context of the clinical scenario. C4 d positivity and DSA,particularly complement fixing,are associated with decreased allograft survival,particularly when detected in the setting of graft dysfunction.
