概括
治疗后持续的慢性活跃T细胞中介排斥 (CA-TCMR) 表明代移植损失的风险较高. 然而,过渡性CA-TCMR与更好的移植存活率有关,突出显示了组织学反应的重要性.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學.
- 移植免疫学 移植免疫学
- 病理学 病理学 病理学
背景情况:
- 慢性活性T细胞中介排斥 (CA-TCMR) 是移植的一个重要问题.
- 虽然治疗可以改善CA-TCMR组织学,但其对长期病预后的影响尚未确立.
研究的目的:
- 为了研究CA-TCMR治疗的组织学反应与移植异位移植存活率之间的关联.
- 为了确定治疗后持续的CA-TCMR是否预测了较差的移植结果.
主要方法:
- 在2018年至2023年期间诊断出CA-TCMR的37名患者的回顾性审查.
- 基于随访活检,将其分为持久性 (11名患者) 和短暂性 (26名患者) 的CA-TCMR组.
- 复合移植终点定义为血清肌素的翻倍或末期脏疾病.
主要成果:
- 在治疗后的两组中都没有观察到血清肌素,EGFR或蛋白尿的显著变化.
- 过渡性CA-TCMR组在间歇性纤维化和管管缩 (IFTA) 和班夫分数方面显著改善.
- 持续的CA-TCMR与显著更差的移植存活率 (p = 0.002) 和经过对临床因素进行调整后的风险增加 (HR: 11.4, p = 0.043) 有关.
结论:
- 治疗后CA-TCMR组织病理的持续性是代移植损失的重要危险因素.
- 过渡性CA-TCMR表明对全移植存活的预后更为有利.

Tissue Transplantation

Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.
