Graft versus host disease (GVHD) following transplantation of an intestine-containing graft occurs more frequently than with other solid organ transplants and is known to have a poor outcome. The presentation differs from other solid organ transplants, as the gastrointestinal tract is not involved following intestinal transplant. Diagnosis is based on clinical symptoms arising due to native tissue damage and the detection of donor T lymphocytes in circulating blood (T-cell chimerism). The ideal treatment strategy has not been defined, with advocates for both increased and decreased immunosuppression. We reviewed all cases of GVHD in an adult intestinal transplant center in the United Kingdom and report on management strategies of five cases and methods of detecting T-cell chimerism. The practice in our center has evolved with experience. The first two patients received an increase in immunosuppression, which was only successful in one case. Subsequently, reducing immunosuppression has been more effective. However, patients with bone marrow involvement have a poorer prognosis. We demonstrate successful treatment of GVHD after multivisceral transplant with a reduction in immunosuppression. This should be followed by vigilant graft surveillance and serial monitoring of the level of T-cell chimerism, with reintroduction of immunosuppression at the earliest sign of graft dysfunction.
移植物抗宿主病(GVHD)在肠移植后比其他实体器官移植更为常见,且预后不良。其临床表现与其他实体器官移植不同,因为肠移植后不会涉及胃肠道。诊断基于因自身组织损伤引起的临床症状和循环血液中供者 T 淋巴细胞(T 细胞嵌合体)的检测。目前尚未确定理想的治疗策略,有人主张增加或减少免疫抑制。我们回顾了英国一家成人肠移植中心的所有 GVHD 病例,并报告了 5 例的治疗策略和 T 细胞嵌合体检测方法。我们中心的做法随着经验的积累而发展。前两名患者接受了增加免疫抑制治疗,但只有一例成功。随后,减少免疫抑制更为有效。然而,骨髓受累的患者预后较差。我们证明了通过减少免疫抑制治疗多器官移植后 GVHD 的成功治疗。这应该伴随着密切的移植物监测和 T 细胞嵌合体水平的连续监测,并在移植物功能障碍的最早迹象时重新引入免疫抑制。
