背景 近期开发的1型糖尿病治疗技术包括多种胰岛素泵以及带有葡萄糖传感器的胰岛素泵。 方法 在这项为期1年的多中心、随机、对照试验中,我们对485例(329名成人和156名儿童)血糖控制不佳的1型糖尿病患者进行了传感器增强型胰岛素泵治疗(泵治疗)与每日多次胰岛素注射方案(注射治疗)疗效的比较。患者接受重组胰岛素类似物治疗,并由专业临床团队进行指导。主要终点是糖化血红蛋白水平较基线的变化。 结果 1年后,泵治疗组的糖化血红蛋白基线平均水平(两组研究对象均为8.3%)降至7.5%,而注射治疗组为8.1%(P<0.001)。泵治疗组的糖化血红蛋白水平达到7.5%或更低的患者比例为47%,而注射治疗组为27%(P<0.001)。严重低血糖发作的频率在泵治疗组为每100患者年31.9次,在注射治疗组为每100患者年36.7次(P = 0.17)。糖尿病酮症酸中毒发作的频率在泵治疗组为每100患者年2.6次,在注射治疗组为每100患者年3.3次(P = 0.44)。 结论 在1型糖尿病患者中,与每日多次胰岛素注射相比,传感器增强型胰岛素泵治疗在改善血糖控制方面更有效,且不会增加严重低血糖或糖尿病酮症酸中毒发作的频率。
BACKGROUNDRecently developed technologies for the treatment of type 1 diabetes mellitus include a variety of pumps and pumps with glucose sensors.METHODSIn this 1-year, multicenter, randomized, controlled trial, we compared the efficacy of sensor-augmented pump therapy (pump therapy) with that of a regimen of multiple daily insulin injections (injection therapy) in 485 patients (329 adults and 156 children) with inadequately controlled type 1 diabetes. Patients received recombinant insulin analogues and were supervised by expert clinical teams. The primary end point was the change from the baseline glycated hemoglobin level.RESULTSAt 1 year, the baseline mean glycated hemoglobin level (8.3% in the two study groups) had decreased to 7.5% in the pump-therapy group, as compared with 8.1% in the injection-therapy group (P
