背景 急性移植物抗宿主病(GVHD)是异基因造血细胞移植的常见并发症。本报告描述了自体移植后的肝脏移植物抗宿主病。 方法 我们回顾了连续116例自体移植受者。GVHD的诊断依据是组织学(胆管上皮细胞节段性至近全破坏,伴有细胞凋亡和淋巴细胞浸润)、临床标准(血清碱性磷酸酶升高)、对免疫抑制治疗的反应,以及未发现其他导致胆汁淤积性肝病的原因。 结果 2例患者发展为胆汁淤积性肝病(碱性磷酸酶水平超过正常上限的5倍),肝活检显示典型的移植物抗宿主病典型的凋亡和变形的导管上皮细胞。另外三名患者出现胆汁淤积和肠道症状,但只有胃活检,显示典型的移植物抗宿主病的隐窝上皮细胞凋亡和隐窝细胞脱落。 结论 两名接受自体造血细胞移植的患者在同种异体移植后出现了小胆管的组织学异常和类似GVHD的淤胆性肝病。这种情况下胆管损伤的机制可能涉及与外周血干细胞重建免疫相关的免疫失调。
BACKGROUND Acute graft-versus-host disease (GVHD) of the liver is a frequent complication of allogeneic hematopoietic cell transplantation. This report describes hepatic GVHD following autologous transplantation. METHODS We reviewed 116 consecutive autologous transplant recipients. A diagnosis of GVHD was based on histology (segmental to subtotal destruction of bile ductal epithelial cells with apoptosis and lymphocytic infiltrates), clinical criteria (elevated serum alkaline phosphatase), a response to immunosuppressive therapy, and finding no other cause for cholestatic liver disease. RESULTS Two patients developed cholestatic liver disease (alkaline phosphatase levels over five times the normal upper limit) and had liver biopsies showing apoptotic and dysmorphic ductular epithelial cells typical of GVHD. Three additional patients developed cholestasis and intestinal symptoms but had gastric biopsies only, showing apoptotic crypt epithelial cells and crypt cell drop-out typical of GVHD. CONCLUSION Two recipients of autologous hematopoietic cells developed histologic abnormalities of small bile ducts and cholestatic liver disease resembling GVHD of the liver after allogeneic transplant. The mechanisms of bile duct damage in this setting may involve immune dysregulation related to reconstitution of immunity with peripheral blood stem cells.
