强化血糖控制降低糖尿病视网膜病变的风险

2016-06-17 MedSci MedSci原创

ACCORDION研究显示,2型糖尿病患者若控制血糖,则发生糖尿病性视网膜病变的风险减少一半。Emily Chew博士指出,这表明糖尿病患者控制血糖对其眼睛健康及视力有重要作用。 Chew和同事对1310名参与ACCORD研究(2003-2009)的民众进行了调查。参与者被随机分配到实验组和对照组(糖化血红蛋白目标值:<6%:7%、收缩压:<120mmhg:140mmhg、血脂:非诺贝

ACCORDION研究显示,2型糖尿病患者若控制血糖,则发生糖尿病性视网膜病变的风险减少一半。Emily Chew博士指出,这表明糖尿病患者控制血糖对其眼睛健康及视力有重要作用。 


Chew和同事对1310名参与ACCORD研究(2003-2009)的民众进行了调查。参与者被随机分配到实验组和对照组(糖化血红蛋白目标值:<6%:7%、收缩压:<120mmhg:140mmhg、血脂:非诺贝特+辛伐他汀160mg或安慰剂加辛伐他汀)。2010年研究人员检查了参与者的眼睛和眼底情况,2014年对参与者的眼睛和眼底情况进行再次评估(2010-2014)。 

ACCORD研究进行的第8年,研究人员发现,相比血脂对照组,血脂实验组患者出现糖尿病视网膜病变的发生率较低(11.8%:10.2%,调整OR=1.13,95%CI:0.71-1.79)。相比血糖对照组,血糖实验组患者出现糖尿病视网膜病变的发生率较低(5.8%:12.7%,aOR=0.42;95% CI:0.28-0.63)。相比血压对照组,血压实验组患者出现糖尿病视网膜病变的发生率较高(7.5%:6%,aOR=1.21,95%CI:0.61-2.4)。

研究结果提供的证据表明,强化血糖控制有利于减少糖尿病性视网膜病变的进展,2型糖尿病患者尤其明显。并可进一步减少患者发生眼睛、肾脏和神经系统并发症出现的风险。但研究人员表示仍需进一步探究加以证实。
