胰岛细胞及肾联合移植治疗胰岛素依赖型糖尿病合并尿毒症四例

目的　观察成人胰岛细胞及肾联合移植治疗胰岛素依赖型糖尿病合并尿毒症的临床效果。方法　对 4例胰岛素依赖型糖尿病合并尿毒症的患者施行成人胰岛细胞及肾联合移植。肾移植为常规术式 ,在移植肾开放血液循环后 ,将分离、纯化、培养好的胰岛细胞注入门静脉中。移植后监测患者的空腹血糖、基础C 酞、糖化血红蛋白及肾功能的变化 ,并与其术前各项指标比较。结果　 4例患者术后在观察期间内胰岛素的用量均较术前减少超过 2 5 % ,且持续 3个月以上 ;空腹血糖基本保持在正常水平 ,基础C 酞也基本维持在正常水平 ,糖化血红蛋白于术后降至正常水平 ;4例患者的移植肾功能良好 ,3例患者已恢复正常工作。结论　成人尸体胰岛细胞及肾联合移植治疗胰岛素依赖型糖尿病合并尿毒症的临床效果较好 ,具有操作简单、安全等优点

Combined kidney and islet cell transplantation in the treatment of 4 patients with type I diabetes agsociated with end-stage renal failure

Objective To observe the clinical effects of combined islet cell and kidney transplantation in the treatment of insulin-dependent diabetes mellitus associated with end-stage renal failure.Methods Four patients with type I diabetes and ESRD received combined renal and islet cells transplantation.Clinical and metabolic data were studied during the follow-up.Results The cultured human adults islet cells were infused into the portal vein system of the 4 patients.Immunosuppression included CsA.azathioprine and prednisone.Metabolic follow-up comprised assessment of daily fasting and non-fasting blood glucose,basal C-peptide secretion,HbAIc,renal function and blood cell counts.Islet isolation yielded 25 000～48 000 equivalents(single or multiple donors).No adverse effects were seen subsequent to islet transplantation.Basal C-peptide secretion maintained at normal levels.and blood glucose and HbAIc levels were normalized throughout the observation period.The dosage of insulin were decreased by over 25% in all 4 patients after transplantation.Conclusions Combined adult islet cells and renal transplantation has a good effect in the treatment of the patients with type Ⅰ diabetes and ESRD and can be used as an effective way for treating ESRD secondary to the type Ⅰ diabetes.Postoperative efficacy is related not only to the quantlty and quality of the islet cells,but also to the rejection of the grafts.
