概括

在ABO不相容的移植后进行2周的异凝素标位测试,可能无法检测晚期抗体中介排斥. 建议扩展监测,以改善ABOi-KT接受者的移植结果.

科学领域:

腎臟病學 (nephrology) 是一種醫學專業.
免疫学免疫学免疫学
移植医学移植医学

背景情况:

由于已经存在的抗ABO抗体,ABO不兼容移植 (ABOi-KT) 具有独特的挑战.
监测异凝素标位对于检测抗体介导排斥 (AMR) 是至关重要的.
目前的协议往往侧重于移植后的短期监测.

研究的目的:

为了评估ABOi-KT.后2周的异凝聚素标位测试期的充分性.
为了确定这种监测持续时间是否足以检测急性AMR.
在特定患者病例中倡导扩大监测.

主要方法:

对接受治疗性血交换 (TPE) 的ABOi-KT患者进行回顾性审查,以提高ABO抗体标位和疑似AMR.
数据收集包括实验室结果,临床信息,成像和移植活检.
分析的重点是2022年1月至2023年12月的病例.

主要成果:

在移植后2周内,发现了3例急性AMR病例.
这些病例同时显示出异凝素标位,肌素和C-反应蛋白的增加.
脏移植活检证实AMR;两名患者需要移植切除术,一名患者用TPE恢复.

结论:

在ABOi-KT后,对异凝素标位进行为期2周的监测期可能不足以检测晚期AMR.
建议延长监测时间,以改善长期移植存活率.
对于高风险患者,建议考虑终身新鲜冷血和定期标位检测.

关键词:

Blood Transfusion and Agglutination

Blood Transfusion and Agglutination

Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

Blood Transfusion

Blood Transfusion

Blood transfusion is a critical medical procedure that saves lives and treats various medical conditions. It involves transferring blood from a donor to a recipient. This process requires a thorough understanding of the ABO blood group system and its associated antigens and antibodies.
Blood Transfusion Overview
A blood transfusion is a medical procedure used to replace blood lost due to injury, surgery, or to treat conditions such as anemia or cancer. During a transfusion, donor blood is...
