摘要
背景 依据国际复合组织移植大会的交流经验和猪异体肢体移植研究成功经验,我们制定了一个人类异体手移植计划。方法 通过全面的移植术前评估和患者的同意,选择移植物大小、性别、皮肤弹性相配的一个58岁的尸体供者的左手移植到一个失去左手13年的男性受者。免疫抑制治疗包括Simulect(一种新型免疫抑制剂,为竞争性IL-2受体阻断剂)诱导治疗和普乐可复、骁悉、强的松龙的维持治疗。结果 供手的冷缺血时间为310分钟。无术中或术后并发症。移植物皮肤在第6、20、27周发生了中等程度的排斥反应。通过静注甲基强的松龙,局部使用普乐可复(FK506)和氯倍他索(Clobetasol)缓解。温度觉、痛觉、压力觉在一年时到达手和手指。在术后一年,患者可以使用左手进行许多假肢没有的功能,例如投掷垒球、翻报纸、写字和系鞋带。结论 利用新型免疫抑制剂获得了异体手移植的早期成功。
Background On the basis of positve results in studies of the transplantation of pig extremities and posium on composite-tissue transplantation, we developed a protocol for human hand transplantation. Methods After a comprehensive pretransplantation evaluation and informed-consent process, the left hand of a 58-year-old cadaveric donor, matched for size, sex, and skin tone, was transplanted to a 37-year-old man who had lost his dominant left hand 13 years earlier. Immunosuppression consisted of basiliximab for induction therapy and tacrolimus, my-cophenolate mofetil, and prednisone for maintenance therapy. Results The cold-ischemia time of the donor hand was 310 minutes. There were no intraoperative or early postoperative complications. Moderate acute cellular rejection of the skin of the graft developed 6, 20 and 27 weeks after transplantation. All three episodes resolved completely after treatment with intravenous methylprednisolone and topical tacrolimus and clobetasol. Temperature, pain, and pressure sensation had developed in the hand and fingers after one year. At one year, the patient could perform many functional activities with his left hand that he had not been able to perform with his prosthesis, such as throwing a baseball, turning the pages of a newspaper, writing, and tying his shoelaces. Conclusions Early success has been achieved in hand transplantation with the use of currently available immunosuppressive drugs.
