目的 探讨自体外周造血干细胞移植治疗成人皮肌炎的疗效.方法 1例21岁皮肌炎患者接受自体外周造血干细胞移植,随访6年.采用重组人粒细胞集落刺激因子动员外周造血干细胞后,予以环磷酰胺、甲泼尼龙、环孢素预处理,干细胞回输第3天开始使用兔抗人T淋巴细胞免疫球蛋白.观察症状体征、生化指标、造血重建及免疫恢复情况.结果 出院时皮疹明显好转,后逐渐消退;四肢肌力由移植前Ⅳ级转为Ⅴ级并持续至今;移植后肌酸激酶显著下降,但又逐渐恢复到移植前水平;回输当天开始出现白细胞下降,第8天恢复正常造血功能.移植前后免疫功能均正常.结论 对复杂难治性重症皮肌炎,可选择白体外周造血干细胞移植治疗.

Autologous peripheral hematopoietic stem cell transplantation in the treatment of adult dermatomyositis: a case report

Objective To investigate the efficacy of autologous peripheral hematopoietic stem cell transplantation in the treatment of adult dermatomyositis. Methods A 21-year-old patient with dermatomyositis received autologous peripheral hematopoietic stem cell transplantation and was followed up for 6 years. Autologous peripheral hematopoietic stem cells were mobilized by recombinant human granulocyte colony stimulating factor (rhG-CSF) before the transplantation, and the conditioning regimens consisted of cyclophosphamide,methylprednisolone and cyclosporin. Rabbit anti-human T lymphocyte immunoglobulin began to be applied on day 3 after retransfer of stem cells. The improvement in symptoms, physical signs and biochemical indicators was observed, and hematopoietic restructuration and immunity resurrection were evaluated after the transplantation. Results After the transplantation, skin eruption greatly improved and gradually subsided. The muscle force of extremities restored from level Ⅳ before transplantation to level Ⅴ. The level of creatine kinase declined sharply after transplantation, but gradually returned to previous level. Leucocyte count began to decrease on the day of retransfer, and returned to the normal level on day 8. Immune function remained normal before and after the transplantation. Conclusion Autologous peripheral hematopoietic stem cell transplantation is an alternative treatment for severe and refractory dermatomyositis.
