Diabetes Care:低血糖与认知功能障碍

2018-11-14 xing.T MedSci原创

由此可见,低血糖并未增加11495名血糖异常的中年人发生认知功能障碍的风险。

流行病学研究报道了中年和老年2型糖尿病患者严重低血糖、认知功能障碍和痴呆之间的关系。然而,尚不清楚严重或非严重低血糖是否发生在认知功能障碍之前。近日,糖尿病领域权威杂志Diabetes Care上发表了一篇研究文章,该研究的目的是通过前瞻性收集甘精胰岛素干预结果(ORIGIN试验)的数据分析了一组精心随访的患者低血糖与认知功能障碍之间的关系。

这项前瞻性队列分析的数据来自随机对照试验,纳入了具有额外血管危险因素和迷你精神状态检查(MMSE)评分≥24(N=11495)的血糖异常个体。在中位随访6.2年期间,研究人员前瞻性地收集了严重和非严重的低血糖事件。认知功能障碍被定义为报告的痴呆或MMSE评分<24。在调整基线血管疾病、糖尿病状态、治疗分组和任何一种低血糖倾向评分后,研究人员使用Cox比例风险模型估计至少一次严重或非严重低血糖事件对于认知功能障碍(即因变量)的风险。

这项分析在调整严重的低血糖倾向之前( HR为1.16,95%CI为0.89-1.52)或之后(HR为1.00; 95%CI为0.76-1.31)均未发现严重低血糖与认知缺损之间存在关联。相反,非严重低血糖与调整之前(HR为0.59; 95%CI为0.52-0.68)和之后(HR为0.58; 95%CI我0.51-0.67)认知障碍之间呈负相关。

由此可见,低血糖并未增加11495名血糖异常的中年人发生认知功能障碍的风险。
