JCEM:GH/IGF-I轴与长寿有什么关系?

2016-11-14 MedSci MedSci原创

多种疾病可以解释生长激素/胰岛素样生长因子r-I (GH/IGF-I)轴与长寿之间的联系。 研究目的是调查循环GH/IGF-I系统蛋白水平和主要健康事件之间的联系。研究纳入2268名≥65岁、没有糖尿病和心血管疾病的参与者。 我们评估了参与者的胰岛素样生长因子结合蛋白-1(IGF-1)水平、空腹和口服葡萄糖耐量试验(OGTT)后2小时的胃饥饿素水平,以及空腹IGF-I和IGFBP-3水

多种疾病可以解释生长激素/胰岛素样生长因子r-I (GH/IGF-I)轴与长寿之间的联系。

研究目的是调查循环GH/IGF-I系统蛋白水平和主要健康事件之间的联系。研究纳入2268名≥65岁、没有糖尿病和心血管疾病的参与者。

我们评估了参与者的胰岛素样生长因子结合蛋白-1(IGF-1)水平、空腹和口服葡萄糖耐量试验(OGTT)后2小时的胃饥饿素水平,以及空腹IGF-I和IGFBP-3水平。复合终点包括首发心肌梗死卒中心衰、髋部骨折或死亡。

在13930人年的随访过程中,48.1%的参与者出现至少一件复合终点事件,31.8%的个体死亡。空腹和餐后2小时胃饥饿素水平最高四分位数者与最低四分位数者比较,复合终点的风险更高(27%,95% CI: 6%, 53%;39%,95% CI: 14%, 71%)。最高四分位数2小时IGFBP-1水平与复合终点风险高出35%有关(95% CI: 1%, 52%)。同样,更高的死亡率与跟高的空腹和餐后2小时胃饥饿素水平、更高的2小时IGFBP-1水平有关。OGTT后2小时IGFBP-1水平和胃饥饿素水平与空腹时这些指标比较,能更高的预测结局。

OGTT后2小时测定循环中IGFBP-1和胃饥饿素水平,能预测老年人群的重大健康事件,这也许可以解释GH-IGF轴对寿命和健康的影响。
