摘要:

背景:原位肝移植是目前治疗终末期肝病的最有效手段,但是供肝来源匮乏、免疫排斥、无法有效控制反复感染等问题限制了其应用。干细胞移植技术的应用为该病种的治疗提供了新的思路和研究方法,许多研究证实可以通过各种不同的方法在体外成功诱导脐血来源的间充质干细胞向肝细胞转化。
目的:探讨人脐血单个核细胞移植治疗失代偿期肝硬化的临床疗效及可行性。
方法:异体人脐血单个核细胞移植治疗23例肝硬化失代偿期患者,检测移植后2,4,8,24周的血清丙氨酸氨基转移酶、白蛋白、胆碱酯酶、总胆红素和凝血酶原时间,并观察患者临床症状体征改善情况以及不良反应。
结果与结论:人脐血单个核细胞移植后2周,肝功能各项指标较治疗前无明显改善(P > 0.05);移植后4周,谷丙转氨酶有显著改善(P < 0.05)、其余指标无明显改善;移植后12周肝功能各项指标均有改善(P < 0.05),且肝脏硬度有所改善(P < 0.05);移植后24周各项指标有显著性改善(P < 0.01)。移植后4周时患者临床症状有明显改善,20例乏力好转(87%)、21例食欲改善(91%)、19例腹水减轻(83%);所有患者移植期间及治疗后随访24周无严重不良反应。结果显示异体人脐血单个核细胞移植治疗肝硬化失代偿期患者临床疗效肯定,安全性好,可作为中晚期肝硬化患者的临床治疗手段。

Abstract:

BACKGROUND: Orthotopic liver transplantation is the most effective therapy for the treatment of end-stage liver diseases, but the lack of donor source, immune rejection, and repeated infections limit its application. Stem cell transplantation technology provides a new idea for the treatment of end-stage liver diseases. A variety of methods have been confirmed to successfully induce umbilical cord blood mesenchymal stem cells converted into liver cells in vitro.
OBJECTIVE: To explore the clinical efficacy and feasibility of human umbilical cord blood mononuclear cells transplantation in the treatment of decompensated cirrhosis.
METHODS: Twenty-three patients with decompensated cirrhosis received allogeneic human umbilical cord blood mononuclear cell transplantation. Serum alanine aminotransferase, albumin, cholinesterase, total bilirubin and prothrombin time were detected at post-transplantation weeks 2, 4, 8 and 24. Improvement in clinical signs and symptoms as well as adverse reactions was observed.
RESULTS AND CONCLUSION: Liver function had no changes at 2 weeks after human umbilical cord blood mononuclear cell transplantation (P > 0.05). At 4 weeks after cell transplantation, serum alanine aminotransferase was improved significantly (P < 0.05), but the other indexes still had no changes. Until 12 weeks after cell transplantation, there were significant improvements in all the liver function indicators (P < 0.05) and the liver stiffness (P < 0.05). By the end of 24 weeks, all the test results were improved significantly (P < 0.01). Clinical symptoms were alleviated, including fatigue improvement in 20 cases (87%), improved appetite in 21 cases (91%), and relieved ascites in 19 cases (83%). No severe adverse reactions were found during the transplantation and 24-week follow-up. These findings suggest that human umbilical cord blood mononuclear cells transplantation is effective and safe for the treatment of decompensated cirrhosis, which can be considered as a clinical therapy for patients with advanced cirrhosis.
