【摘要】:目的探讨肝移植术后急性移植物抗宿主病(aGVHD)的诊断和治疗。方法选取2011年4月-2016年8月北京佑安医院肝移植中心收治的8例肝移植术后aGVHD患者,总结其诊断要点和治疗经验。结果肝移植术后aGVHD诊断要点:(1)好发时间为肝移植术后2周~2个月;(2)典型临床表现为发热、皮疹、腹泻以及全血细胞水平下降;(3)供体T淋巴细胞比例>10%;(4)有典型的组织病理学表现。治疗经验:类固醇的总反应率约为20%~50%,建议应用甲基泼尼松龙1.5 mg·kg-1·d-1,用药时间为1周。不推荐使用大剂量糖皮质激素,以避免提升感染的发生率;大剂量的免疫抑制剂是导致aGVHD发生的原因之一,临床应注意避免过量应用免疫抑制剂;预防呼吸道感染和消化道感染十分重要;重视肠内营养;siplizumab、抗胸腺细胞球蛋白和TNFα抑制剂等二线疗法可能发挥一定的治疗作用;血液净化可有效清除体内细胞因子和炎症介质有助于aGVHD的治疗。结论发病时间、临床症状、外周血T淋巴细胞嵌合率和组织病理是肝移植术后aGVHD的诊断要点,激素冲击、减低免疫抑制剂剂量可能是有效的治疗手段。
【Abstract】:ObjectiveTo investigate the diagnosis and treatment of acute graft-versus-host disease (aGVHD) after liver transplantation. MethodsThis report included 8 patients treated with liver transplantation who were admitted to the Liver Transplantation Center of Beijing YouAn Hospital from April 2011 to August 2016. The key points in the diagnosis of aGVHD and the experience in the treatment of this disease were summarized. ResultsThe key points in the diagnosis of aGVHD after liver transplantation were as follows: (1) aGVHD usually occur at two weeks to two months after liver transplantation; (2) fever, rash, diarrhea, and reduced whole blood cell count are typical clinical symptoms; (3) the percentage of donor T lymphocytes in peripheral blood is more than 10%; (4) there are typical histopathological manifestations. The experience in the treatment of aGVHD after liver transplantation were as follows: the overall steroid response rate is 20%-50%, and methylprednisolone (1.5 mg·kg-1·d-1, one week) is recommended; high-dose glucocorticoids are not recommended, thus avoiding increased infection risk; high-dose immunosuppressant is one of the causes of aGVHD, and excessive application of immunosuppressant should be avoided in clinical practice; the prevention of respiratory infection and digestive tract infection was very important; enteral nutrition should be considered; second-line therapies such as siplizumab, antithymocyte globulin, and tumor necrosis factor-alpha inhibitor may play a certain therapeutic role; blood purification can be used to effectively eliminate cytokines and inflammatory mediators, which is helpful to the treatment of aGVHD. ConclusionThe diagnostic criteria for aGVHD after liver transplantation are mainly based on time of onset, clinical symptoms, peripheral blood T lymphocyte chimerism rate, and histopathology. Hormone shock and reducing the dose of immunosuppressant may be effective treatments.
