脑内胰岛移植治疗Ⅰ型糖尿病

INTRACEREBRAL PANCREAS ISLET TRANSPLANTATION FOR THE TREATMENT OF TYPE I DIABETES MELLITUS

本研究采用培养的人胎儿胰岛组织脑内移植治疗Ⅰ型糖尿病患者10例,其中7例已完全撤离胰岛素治疗达2～13个月,2例每日胰岛素剂量较移植前分别减少37％和64％,病情控制良好,无效者1例。本研究结果表明,脑内胰岛移植治疗Ⅰ型糖尿病临床效果显著,移植物可能在患者脑内成活。

Ten cases of type I diabetes mellitus were treated with intracerebral pancreas islet transplantation. In 7 cases insulin has been totally stopped for 2 to 13 months, in other 2 cases the dosages of insulin had a decrease of 37% and 64% than that before transplantation respectively, and good control was achieved in those 9 patients. Only one case had not any improvement. The results showed that it is an effective therapy for type I diabetes mellitus and indicated that the pancreas islet was survived in patient's cerebrum and secreted insulin. No evidence of immunological rejection was found. Long-term follow-up is necessary to find how long the allogenic graft can survive.
