ADA 2016:生活压力会增加遗传风险儿童的糖尿病风险

美国糖尿病协会科学会议上称,生活压力会增加HLA-DR3/4基因型儿童的胰岛自身免疫和糖尿病风险。

佛罗里达州立大学医学院杰出的研究教授Suzanne B. Johnson博士和同事对来自TEDDY研究的6岁以上儿童进行了研究,评估负性生活事件与胰岛自身免疫之间的关系。

TEDDY研究对3个月-15岁的8676名遗传风险儿童进行了胰岛自身免疫与1型糖尿病风险的研究。研究者们对影响父母和影响孩子的负面生活事件进行了区分。负性生活事件分为三类:纳入研究后1年内发生的早期负性生活事件;胰岛自身免疫前一年的最近的负性生活事件;累积的负性生活事件。

数据显示,在任何一年中,约有25%的儿童经历负性生活事件;年复一年约有10%的儿童经历了持续的负性生活事件。HLA-DR3/4基因型儿童经历的累积负性生活事件与胰岛自身免疫风险增加独立相关(P < .003);对其他HLA风险的儿童而言,联系不存在(相互作用P值 < .009)。

“我们现在知道压力对一些遗传风险儿童的1型糖尿病的发展是很重要的,但我们还不知道压力是如何导致这些儿童出现抗体阳性,”Johnson说,“我们确实知道应激会影响免疫功能,但这是如何转化为对胰腺β细胞的自身免疫性攻击仍是未知的。当然压力增加了其他疾病的风险反过来导致抗体阳性也是可能的。虽然我们不知道答案,但这项研究结果为进一步的研究提供了一个重要的方向。”
