JCEM:长期1型糖尿病患者从连续血糖监测获益几何?

2017-12-01 MedSci MedSci原创

大家都知道长期的1型糖尿病患者(T1D)由于葡萄糖反调节和低血糖症状识别的缺失,其严重低血糖的风险也在增加。近日在JCEM上发表的一篇文章则旨在确定为规避低血糖发生而采用的实时连续血糖监测(CGM),能否提高并发未察觉低血糖的长期T1D患者的葡萄糖反调节。

大家都知道长期的1型糖尿病患者(T1D)由于葡萄糖反调节和低血糖症状识别的缺失,其严重低血糖的风险也在增加。近日在JCEM上发表的一篇文章则旨在确定为规避低血糖发生而采用的实时连续血糖监测(CGM),能否提高并发未察觉低血糖的长期T1D患者的葡萄糖反调节。

研究人员对11例病程长达31年的T1D患者在CGM开始之前、6个月和18个月后进行了纵向研究,并与12例非糖尿病对照。主要的测量结果是内源性葡萄糖生成对于配对高胰岛素阶梯的低血糖和正常血糖钳夹技术联合注入6,6-2H2-葡萄糖的反应。

研究结果显示T1D患者的低血糖意识(克拉克评分)和严重程度上升(低评分和严重事件;两者p<0.01),而HbA1c没有变化(基线水平7.2± 0.2%)。对胰岛素诱导的低血糖反应,内源性葡萄糖生成在CGM之前和之后6个月并没有改变(0.42 ± 0.08 vs. 0.54 ± 0.07 mg·kg-1·min-1),但是在18个月之后得到改善(0.84 ± 0.15 mg·kg-1·min-1; P <0.05 vs. CGM之前),尽管小于对照组(1.39 ± 0.11 mg·kg-1·min-1; P ≤0.01 vs. 所有)。

由上述研究结果可以看出实时CGM能提高长期T1D患者的意识及减少其低血糖问题的负担,但是在内源性葡萄糖生成方面仅有轻微改善,这就需要防止或及时纠正低血糖。
