科学领域:

  • 移植免疫学 移植免疫学
  • 器官保护科学 器官保护科学
  • 手术方面的创新.

背景情况:

  • 胰腺和小岛移植面临器官短缺,限制了患者的获取.
  • 由于缺血-再输液损伤的担忧而丢弃移植,特别是来自DCD捐赠者的移植,加剧了短缺.
  • 目前的静态冷库对接种子的保存有重大限制.

研究的目的:

  • 审查胰腺和小岛移植的新保存技术.
  • 评估这些技术在改善移植结果和扩大捐赠池方面的潜力.
  • 为了应对利用来自循环死亡 (DCD) 后捐赠者的移植所面临的挑战.

主要方法:

  • 审查器官保存技术的最新进展,包括机器输液 (低温和正常热).
  • 使用新的保存方法分析胰腺利用率和移植存活率的数据.
  • 评估与先进的保存策略相关的临床前和临床发现.

主要成果:

  • 在DCD捐赠者中,正常热区域输液增加了胰腺利用率,移植后一年的存活率与脑死亡 (DBD) 捐赠者捐赠后的存活率相当.
  • 低温机器输液证明了维持组织完整性的临床前前期承诺.
  • 氧化低温机器输液成功地恢复了ATP水平而无损伤;正常热机器输液显示了可行性评估的潜力.

结论:

  • 先进的保存技术为移植评估,恢复和治疗干预提供了平台.
  • 临床转换需要就优化 perfusion 参数和 perfusate 组成达成共识.
  • 未来的努力必须专注于敏感的评估方法,包括β细胞生物标志物,用于选择边缘移植.
